This code does provide me the values I am wanting in my comboBox, but I am wondering if there is a way to get the viewColumn ID, viewColumnHeader ID, and number of columns in the viewPanel programmatically. The viewPanel is using a JDBCQuery as the datasource.
var itemList:java.util.Vector = new java.util.Vector;
var colID = "viewColumn"; //default id assigned
var colHeaderID = "viewColumnHeader"; //default id assigned
var end = 10; //max # of viewPanel columns
itemList.add("Select Column");
for(x=1;x<end;x++) {
try {
if(getComponent(colID + x) == null) {
throw ("Only " + (x-1) + " columns in ViewPanel");
x=end;
} else {
var disColID = getComponent(colID + x).getColumnName();
}
var disColHeaderID = getComponent(colHeaderID + x).getValue();
itemList.add(disColHeaderID + "|" + disColID);
} catch (e) {
dBar.info(e.toString());
}
}
itemList
The current way is obviously restricted to only 9 columns and ensuring the viewColumn ID and viewColumnHeader ID have a specific naming structure which would be nice to get away from.
All the columns of a view panel can be accessed by getting the child components of view panel using viewPanelObj.getChildren(). The column headers are a part of view column and after you get the handle of view column you can access the header using viewColumnObj.getHeader().
So a sample SSJS code to access all the view columns and view headers would look something like this:
var viewPnl:com.ibm.xsp.component.xp.XspViewPanel = getComponent("viewPanel1");
var list:java.util.List = viewPnl.getChildren();
for (var i=0 ; i<list.size() ; i++) {
var viewCol:com.ibm.xsp.component.xp.XspViewColumn = list.get(i);
var viewHdr:com.ibm.xsp.component.xp.XspViewColumnHeader = viewCol.getHeader();
// Perform required operations on objects of viewCol & viewHdr
}

How do I get the selected items is a list, combobox etc?
I found this bit of code here:
/*****
*** getSelectableValues()
*** prints all selectable values for a given component, f.e. comboboxes, listboxes etc.
***
*** #params id of component
*****/
function getSelectableValues( id ) {
var ComboBox = getComponent( id );
var ChildrenList:java.util.ListIterator;
ChildrenList = ComboBox.getChildren().listIterator();
while (ChildrenList.hasNext()) {
var Child = ChildrenList.next();
/*** process computed / multiple values ***/
if( typeof( Child ) == 'com.ibm.xsp.component.UISelectItemsEx' ){
var hlp = Child.getValue();
for( var i=0; i< hlp.length; i++ ){
/*** print to server console ***/
print( hlp[i].getLabel() + "|" + hlp[i].getValue() );
}
}
/*** process single values ***/
if( typeof( Child ) == 'com.ibm.xsp.component.UISelectItemEx' ){
/*** print to server console ***/
print( Child.getItemLabel() + "|" + Child.getItemValue() );
}
}
}
/*** get all selectable values for element 'comboBox1' ***/
getSelectableValues( 'comboBox1' );
But it seems to get ALL of the items in a list box and not just the selected ones. Any ideas how to modify it to get just the selected values?
Instead of asking the component, ask the data model. For instance, if the list box is bound to:
#{someDoc.someItemName}
...then you can retrieve the selected values by asking the data source:
var selectedValues = someDoc.getValue("someItemName");
If the component is instead bound to a scoped variable:
#{viewScope.selectedValues}
...then just ask that variable:
var selectedValues = viewScope.get("selectedValues");
You can access the selected values with SSJS:
getComponent('comboBox1').value
If you are working with a list box and multiple selection is enabled, you can use Explode to get an array of strings:
#Explode(getComponent('listBox1').value)
Hi can some one please tell me how to copy one data store to another in dojo. I tried it in following way but it doesn't work. Here I'm try to copy data from jsonStore to newGridStore.
jsonStore.fetch({query:{} , onComplete: onComplete});
var onComplete = function (items, request) {
newGridStore = null;
newGridStore = new dojo.data.ItemFileWriteStore({
data : {}
});
if (items && items.length > 0) {
var i;
for (i = 0; i < items.length; i++) {
var item = items[i];
var attributes = jsonStore.getAttributes(item);
if (attributes && attributes.length > 0) {
var j;
for (j = 0; j < attributes.length; j++) {
var newItem = {};
var values = jsonStore.getValues(item, attributes[j]);
if (values) {
if (values.length > 1) {
// Create a copy.
newItem[attributes[j]] = values.slice(0, values.length);
} else {
newItem[attributes[j]] = values[0];
}
}
}
newGridStore.newItem(newItem);
}
}
}
}
Based on the comments asked above. You are trying to copy values to a new Store for the single reason to be able to detect which values have changes and then save them individually, without having to send the entire store.
This approach is totally wrong.
Dojo has isDirty() and offers you the ability to revert() a store back to it's original values. It knows which values have changed and you don't need to do this.
Take a look at the bog standard IFWS here: http://docs.dojocampus.org/dojo/data/ItemFileWriteStore
Make sure you read everything from here: http://docs.dojocampus.org/dojo/data/ItemFileWriteStore#id8
What you want to do is create your own _saveCustom method which you will override your store with, and then when you save, you will be able to see which values have changed.
Click on the demo at the very bottom of the page. It shows you EXACTLY how do to it using _saveCustom
Using sharepoint build in lookup column and it set to required field. SharePoint automatically selects the first item in the dropdown box (kinda misleading for the end users).
Is there a way to display blank or Null for the first row of this drop down box?
(I am open to any solution. I prefer javascript type solution)
For Choice fields, the default value is configured in the column settings. If the "Default value" input box is populated, delete the value in order to use no default value.
Edit
For Lookup fields, the field seems to change dramatically if it is required. Fields that are NOT required have a "(None)" value by default. However, toggling the field to required will remove the "(None)" value and the first value is selected automatically.
One thing I found, is that if you use JavaScript to add the null value to the dropdown and then try to press OK you get an error page: "An unexpected error has occurred." As a workaround, I wrote some more code to do a quick validation that the field has a value before the form is submitted. If the field has no value, then it will prompt the user and cancel the submit. (Note: this code is only attached to the OK buttons so you may get errors while editing EditForm.aspx.. just choose a value for your lookup field and you'll be able to edit like normal)
Anyways, onto the code... I think the only line you'll need to change is var fieldTitle = 'Large Lookup Field'; to update it to the name of your field.
<script type="text/javascript">
function GetDropdownByTitle(title) {
var dropdowns = document.getElementsByTagName('select');
for (var i = 0; i < dropdowns.length; i++) {
if (dropdowns[i].title === title) {
return dropdowns[i];
}
}
return null;
}
function GetOKButtons() {
var inputs = document.getElementsByTagName('input');
var len = inputs.length;
var okButtons = [];
for (var i = 0; i < len; i++) {
if (inputs[i].type && inputs[i].type.toLowerCase() === 'button' &&
inputs[i].id && inputs[i].id.indexOf('diidIOSaveItem') >= 0) {
okButtons.push(inputs[i]);
}
}
return okButtons;
}
function AddValueToDropdown(oDropdown, text, value, optionnumber){
var options = oDropdown.options;
var option = document.createElement('OPTION');
option.appendChild(document.createTextNode(text));
option.setAttribute('value',value);
if (typeof(optionnumber) == 'number' && options[optionnumber]) {
oDropdown.insertBefore(option,options[optionnumber]);
}
else {
oDropdown.appendChild(option);
}
oDropdown.options.selectedIndex = 0;
}
function WrapClickEvent(element, newFunction) {
var clickFunc = element.onclick;
element.onclick = function(event){
if (newFunction()) {
clickFunc();
}
};
}
function MyCustomExecuteFunction() {
// find the dropdown
var fieldTitle = 'Large Lookup Field';
var dropdown = GetDropdownByTitle(fieldTitle);
if (null === dropdown) {
alert('Unable to get dropdown');
return;
}
AddValueToDropdown(dropdown, '', '', 0);
// add a custom validate function to the page
var funcValidate = function() {
if (0 === dropdown.selectedIndex) {
alert("Please choose a value for " + fieldTitle + ".");
// require a selection other than the first item (our blank value)
return false;
}
return true;
};
var okButtons = GetOKButtons();
for (var b = 0; b < okButtons.length; b++) {
WrapClickEvent(okButtons[b], funcValidate);
}
}
_spBodyOnLoadFunctionNames.push("MyCustomExecuteFunction");
</script>
In response Kit Menke, I've made a few changes to the code so it will persist previous value of the dropdown. I have added the following lines of code to AddValueToDropdown()....
function AddValueToDropdown(oDropdown, text, value, optionnumber){
var selectedIndex
if (oDropdown.options.selectedIndex)
selectedIndex = oDropdown.options.selectedIndex;
else
selectedIndex = -1;
// original code goes here
// changed last line of code (added "selectedIndex+1")
oDropdown.options.selectedIndex = selectedIndex+1;
}
To improve on top of Aaronster's answer: AddValueToDropdown can be done that way:
var injectedBlankValue = false;
function AddValueToDropdown(oDropdown, text, value, optionnumber) {
for (i = 0; i < oDropdown.options.length; i++) {
option = oDropdown.options[i];
if(option.getAttribute('selected')) // If one is already explicitely selected: we skip the whole process
return;
}
var options = oDropdown.options;
var option = document.createElement('OPTION');
option.appendChild(document.createTextNode(text));
option.setAttribute('value', value);
if (typeof (optionnumber) == 'number' && options[optionnumber]) {
oDropdown.insertBefore(option, options[optionnumber]);
}
else {
oDropdown.appendChild(option);
}
// changed last line of code (added 'selectedIndex+1')
oDropdown.options.selectedIndex = 0;
injectedBlankValue = true;
}
This is needed for document libraries where "add" and "set properties" are two distinct pages.
And funcValidate starts with:
var funcValidate = function () {
if (!injectedBlankValue)
return true;
All these changes is to make the whole thing work with document libraries.
I need to show the ID field in the Edit Form of a sharepoint list.
There is a way to do it ? I tried a calculated field and nothing.
I know that I can see the ID field in the view, and if I show as a Access Mode.
I'm using WSS3.0
You can add the ID field to the form using some JavaScript in a CEWP.
<script type="text/javascript"
src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js">
</script>
<script type="text/javascript">
$(function() {
// Get the ID from the query string
var id = getQueryString()["ID"];
// Find the form's main table
var table = $('table.ms-formtable');
// Add a row with the ID in
table.prepend("<tr><td class='ms-formlabel'><h3 class='ms-standardheader'>ID</h3></td>" +
"<td class='ms-formbody'>" + id + " </td></tr>");
})
function getQueryString() {
var assoc = new Array();
var queryString = unescape(location.search.substring(1));
var keyValues = queryString.split('&');
for (var i in keyValues) {
var key = keyValues[i].split('=');
assoc[key[0]] = key[1];
}
return assoc;
}
</script>
There is an alternative method that doesn't use the jQuery library if you prefer to keep things lightweight.
You can do this by creating a custom edit form quite easily. I usually stick it into an HTML table rendered within a webpart. There may be a better way of doing that but it's simple and it works.
The key line you'll want to look at is spFormField.ControlMode. This tells SharePoint how to display the control (Invalid, Display, Edit, New). So what you'll want to do is check if your spField.InternalName == "ID" and if it is, set the ControlMode to be Display.
The rest is just fluff for rendering the rest of the list.
Hope this helps.
HtmlTable hTable = new HtmlTable();
HtmlTableRow hRow = new HtmlTableRow();
HtmlTableCell hCellLabel = new HtmlTableCell();
HtmlTableCell hCellControl = new HtmlTableCell();
SPWeb spWeb = SPContext.Current.Web;
// Get the list we are going to work with
SPList spList = spWeb.Lists["MyList"];
// Loop through the fields
foreach (SPField spField in spList.Fields)
{
// See if this field is not hidden or hide/show based on your own criteria
if (!spField.Hidden && !spField.ReadOnlyField && spField.Type != SPFieldType.Attachments && spField.StaticName != "ContentType")
{
// Create the label field
FieldLabel spLabelField = new FieldLabel();
spLabelField.ControlMode = _view;
spLabelField.ListId = spList.ID;
spLabelField.FieldName = spField.StaticName;
// Create the form field
FormField spFormField = new FormField();
// Begin: this is your solution here.
if (spField.InteralName == "ID")
{ spFormField.ControlMode = SPControlMode.Display; }
else
{ spFormField.ControlMode = _view; }
// End: the end of your solution.
spFormField.ListId = spList.ID;
spFormField.FieldName = spField.InternalName;
// Add the table row
hRow = new HtmlTableRow();
hTable.Rows.Add(hRow);
// Add the cells
hCellLabel = new HtmlTableCell();
hRow.Cells.Add(hCellLabel);
hCellControl = new HtmlTableCell();
hRow.Cells.Add(hCellControl);
// Add the control to the table cells
hCellLabel.Controls.Add(spLabelField);
hCellControl.Controls.Add(spFormField);
// Set the css class of the cell for the SharePoint styles
hCellLabel.Attributes["class"] = "ms-formlabel";
hCellControl.Attributes["class"] = "ms-formbody";
}
}
On custom edit page of list item, I want to do the following
- On clicking Form Action Hyperlink [DataView Control], custom form action will fire to update
a item hidden field [Status].
I already tried the following
- Passing #ID to the work flow but didnt work
- Create a duplicate ID column and updated it with the ID on Item Creation. and then tried to access in "Update Item in" Action but getting "An unexpected error has occurred" while running it.
[Remember i can only use sharepoint designer]
Try to use these javascript functions:
function GetQueryVariable(variable) {
var query = window.location.search.substring(1);
var vars = query.split("&");
for (var i = 0; i < vars.length; i++) {
var pair = vars[i].split("=");
if (pair[0] == variable) {
return pair[1];
}
}
}
function GetCurrentItem() {
var itemId = GetQueryVariable("ID");
try {
var context = new SP.ClientContext.get_current();
var web = context.get_web();
var list = web.get_lists().getByTitle('list-title');
this.currItem = list.getItemById(itemId);
context.load(currItem);
context.executeQueryAsync(Function.createDelegate(this, this.funcSuccess), Function.createDelegate(this, this.funcFailed));
}
catch (e) {
alert(e);
}
}
function funcSuccess() {}
function funcFailed() {}
