How do I read the value of context menu checkbox? - google-chrome-extension

I'm trying to create a Chrome extension that a user might want to frequently enable/disable. To facilitate this, I'd like to add a checkbox to the context menu that basically says "extension enabled". When a page loads, it would check to see if there was a check by the context menu item. I have created the menu item, and it stays persistent throughout page loads, but I don't know how to read its value. Can anyone help me out?
Here is the code that I'm using to add the checkbox to the context menu.
var checkbox1 = chrome.contextMenus.create({
"title": "Enable",
"type": "checkbox",
"onclick":enableAutofilter
});

From the Chrome docs, it appears that there is no way to read information about a context menu item. There are create, update, and remove functions, but no read function (so it has only three of the CRUD operators). This means that you'll have to maintain the on/off state elsewhere, e.g., on your background page and/or in localStorage, and toggle it when you fire enableAutoFilter.

Is it possible to attach event on the *opening* of the context menu?

I am developing a WebExtension and as you know it is impossible to inject content script on chrome://* pages and https://chrome.google.com/webstore/*. I have a buttons in a context menu and for correct UX I would like to drop my item from context menu on such protected page.
According to the documentation I can handle click on my context menu item, but looks like no way to check the url of the page on the moment of right mouse click without trying to inject content script into every page?
As a workaround I have a code that checks url after click to the menu item.

CRM 2011 Sub-Grid: Call JavaScript On-Click or On-Focus

How can JavaScript execute when a sub-grid receives focus?
I have a sub-grid that shows all Cases associated with an Account.
I would like to disable some fields on the form when the sub-grid receives focus.
RibbonDiffXML action for a ribbon button:
<Actions>
<JavaScriptFunction Library="$webresource:mda_convertemailtocaselib" FunctionName="ConvertEmailToCaseLib.addToCase">
<CrmParameter Value="SelectedControlSelectedItemIds" />
</JavaScriptFunction>
</Actions>
This passes the sub-grid select items to a ribbon button, but I would like the JavaScript to execute before the ribbon button is pressed.
I haven't tried either of these out, but hopefully one of them should work for you.
Although it is a subgrid, there still is a control on the form. Unfortunately there is no "supported" way to know when a control gets focus since there aren't any OnFocus/OnBlur methods exposed via the CRM JS API. However you should be able to add your own JS event handler for that control and disabled the fields via the API Xrm.Page.getControl("fieldname").setDisabled(true)
I'm not 100% sure if this way would work, but it would be pretty sweet. Create a CustomRule EnableRule. In this CustomRule you call your own JS. In this create a function where you disable the fields and then return true to make the button enabled. It would look something like this:
function disableFieldsEnableRule() {
Xrm.Page.getControl().setDisabled(true);
...
...
return true; // so the button is enabled
}
The only reason I'm not sure if this will work is because I'm not sure if the Enable rules are checked each time you click on the subgrid or just the first time (I think it should be every time). Also I'm not sure if you want those fields re-enabled once you click off. If you do you might have to do something similar to this with a button on the native form, or something else.

XPages remove documents on server and trigger partial refresh

I am struggling with the following.
On my XPage I have a viewpanel component, but it is not bound to a notesview datasource, but to a hashmap stored in viewScope. Reasons for this is beyond scope of my question.
Since the lines in my view are not actually linked to the documents I cannot use the standard checkboxes and the related getSelectedDocIds. I do however want a way to remove the selected documents. I have a column with checkboxes containing the unid of the corresponding row.
So long story short. I have an array of unids and want to perform an action that does the following:
Display a dijit.Dialog asking for confirmation
If OK clicked call a function that does the following:
Remove the documents based on the unids
Refresh the viewpanel
I am thinking of the following 2 solutions, but in doubt what would be best (maybe a third, even simpler solution?)
Have the OK button of the dojo dialog call a function that does an XmlHttpRequest to an XAgent or plain old LS agent
Have the OK button trigger an eventhandler that runs on the server as described by JeremyHodge here. But how would I pass the unids as parameter and refresh the view afterwards?
Thanks!
Cant you just make use of the extension library dialog with the dialog button control. In this button control you can then
A third option would be to add a column to your datatable/view which contains checkboxes. On the onchange event of these boxes you add an eventhander which adds the value to a viewScope variable.
A button on the bottom (or top.) of the page you add the code you need to remove the selected items from the hashmap, delete the documents associate with the selected id's. this button can be a ordinary button with a partial refresh on the viewpanel. When you run into the bug that you cant use buttons in a dialog please use the extension library dialog control because this fixes that issue for you.
If the current user does not have the correct access level to delete documents you could use the sessionAsSigner global (assuming the signer of the design element has the correct access levels).
This way you dont need to go call an xAgent by xmlthttprequest and can stay with the default xpage methodology.
I hope this helps in some way
I would second #jjbsomhorst in the use of the extension library for the dialog box - if you use one at all. Usually users don't read dialog boxes. So the approach would be add the column with the checkboxes, but don't bother with an event handler, but bind them ALL with their value to ONE scopeVariable. On submission that variable will then hold an array with the selected UNID.
Then render a page that lists these documents and have a confirm button. While the new page affords a server round-trip the likelihood, that users actually pay attention is way higher. What you can do:
Have the normal page that renders the dialog with editable checkboxes and when the user clicks "Delete" you set something like viewScope.confirmDeleteMode=true; and use that as condition for the checkboxes and make them read-only AND set the class of the selected rows to "morituri" which in your CSS would have something like .morituri { color: white; background-color : red; font-weight: bold } and a new button "Confirm Delete" (and hide the Delete button).
This way you only have one page to deal with.
I went for option 2, which has the possibility to provide the partial refresh id. I passed the unids as a submitvalue like:
function doRemove(unids){
XSP.executeOnServer(ISP.UI.removeEventID, ISP.UI.removeRefreshID, {
params: {
'$$xspsubmitvalue': unids
},
onComplete : function() {
//alert('test')
}
});
}
The ISP.UI.removeEventID performs the following code:
var unids = context.getSubmittedValue();
removeDocuments(unids); //SSJS function performing the actual delete
viewScope.reload = 'reload' //triggers the hashmap to be rebuild based on new documentcollection

Extension-Specific Context Menu

I'm trying to add an item to the right-click menu on my extension. I've tried to find a method which would work, but a lot of the results seem to deal with context menus on the actual page, not the extension icon itself. The contextMenus API doesn't seem to work for this, unfortunately.
There is currently no API for that. Head for Chromium Issue 78631 and click the star to cast your vote for it and receive updates by e-mail. In the meantime, you could create a popup with a menu that lists both the primary action and the actions you would have put in the context menu.
(I assume you're trying to add the context menu item to your browser action. Your question is a little ambiguous.)

Can Popup page use DOM elements created in Background Page

Actually, I want to store some data in background page and the popup page just show that part of data say Data as a div element created in background page document.createElement("div"). Here, the background page will register some listeners to the tab update and change the Data elements accordingly. What the popup will do is to get that Data and appendit use the document.appendChild(Data).
(The purpose I intend is this will cause the popup changes immediately while the tab updage is triggered.)
However, the elements are shown as usual, what I am facing very headache is I have registered the onclick for the div object in backgroundpage as onclick="chrome.extension.getBackgroundPage().somefunc()". However, the first time, all the click will triger the right behavior but after the popup loses foucs and get focus again, all the click won't work.
I try to put something like change the onclick="somefunc()" and leave the func within the script of popup page. And there I want to log whether it is called by console.log("clicked"). Here, something unbelievable happens, the function is succefully trigerred BUT the console is null here, I cannot even call chrome.extension.getBackgroundPage() as well.
Here are a list of questions, maybe very hard to express for me...
1. Whether I can reuse the DOM element from the background page to the popup page directly by appendChild(chrome.extension.getBackgroundPage().getElementById()?
2.Will the onclick event registered in the background page still work in the popup pages?
3. What's the problem with the problem I am encountering? I have tried many ways to find out the reason but all in vain at last...
Best Regards,
If you need any more information, please let me know.
(PS: I am wonderning if it is called something like the event propogation, however, I am not an expert in this two pages communicating...)
