I want to ask a question that how can i get the parent id of child node in aciTree. If uservchecked the child node then i want to save its id with its parent id.
Any help in this regard will be highly appreciated.
I have gone through aciTree documentation http://acoderinsights.ro/source/aciTree/documentation.html# but didn't found any method to get the parent id on child selection.
if (eventName == 'checked') {
if (bankUsers.indexOf(api.getId(item)) == -1) {
if (api.getId(item) == -2 || api.getId(item) - 3) {
bankUsers = new Array();
bankUsers[0] = api.getId(item);
} else {
bankUsers.push(api.getId(item));
}
}
} else if (eventName == 'unchecked') {
if (bankUsers.indexOf(api.getId(item)) != -1) {
if (api.getId(item) == -2 || api.getId(item) - 3) {
bankUsers = new Array();
} else {
bankUsers.splice(bankUsers.indexOf(api.getId(item)), 1);
}
}
}
you can use this function :
var parentID = api.itemData(api.parent(item)).id;
as simple as this.
if .id give undefiend you can use the following:
var parentID = api.getId(api.parent(item));

I have written quite a few different add-ins now but I keep struggling to get a windows form working on Revit. The program builds fine and I have the dll set up for Revit to access.
Here are the different sections of my code. The program is more extensive than what is seen but I believe that the problem is a reference issue or a problem with my ADDIN file. Maybe there is a different way I need to set up my ADDIN file since I have a windows form in it?? Let me know.
Here is a Dropbox folder with the screenshots in it.
Let me know if there is anything else you need to see. The error in Revit says it has to do with the FullName but I believe I put it in the ADDIN file correctly, and I did it the same as I had for other ADDINs.
Thank you for your help!

This code is having the functionality in the 'main class.' I have since moved the functionality to the form class as konrad suggested but am still receiving the FullClassName error in Revit. Please Help!
The schedule data add-in provides a full Visual Studio solution demonstrating how to display a Windows form in a Revit add-in, including the generation of the Windows form on the fly:
http://thebuildingcoder.typepad.com/blog/2012/05/the-schedule-api-and-access-to-schedule-data.html
Here's how I usually set up my Windows Forms based External Commands. Remember that you have to create an External Command, and your addin manifest must point at this class. Then from this class you can launch the Form like so:
[Transaction(TransactionMode.Manual)]
public class SomeCommand : IExternalCommand
{
public Result Execute(
ExternalCommandData commandData,
ref string message,
ElementSet elements)
{
// Get application and document objects
UIApplication uiApp = commandData.Application;
Document doc = uiApp.ActiveUIDocument.Document;
UIDocument uidoc = uiApp.ActiveUIDocument;
try
{
SomeNamespace.SomeForm form = new SomeNamespace.SomeForm(doc);
form.ShowDialog();
return Result.Succeeded;
}
// Catch any exceptions and display them
catch (Autodesk.Revit.Exceptions.OperationCanceledException)
{
return Result.Cancelled;
}
catch (Exception ex)
{
message = ex.Message;
return Result.Failed;
}
}
}
So I have a Form class that I instantiate from my ExternalCommand and pass Document to its constructor. That way I have access to document when I am interacting with the form later. I wire up all functionality in code behind of the Form.
Agree, the OP's question is why doesn't the addin work...
From looking at the images, it seems like the issue is that Revit is not properly finding the full class name of the command.
It's a little unusual that you don't have your command class wrapped in a namespace (your form class is, for example).
I would recommend wrapping it in a namespace like "circuitchecker" - like your form class.
Then the "full name" in the addin file would become "circuitchecker.circuitchecker"
(the namespace.classname) - this helps Revit distinguish different classes that might have the same name.
side note: I don't believe that putting a URL into the Image/LargeImage fields in the addin will work - but not positive.
Is there a way in Intern that I can poll until an element is visible? A lot of elements in my website are in the dom but are hidden, so every time I do a "find for" element X after it is supposed to appear, it fails because the element clearly breaks one of the visible attributes that selenium checks.
I've tried the helper function "pollUntil" but I can't seem to get that to work. Dojo seems to not like document.getElement*()
Helper Function that is passed into pollUntil
//this is a helper function for pollUntil
//first we want to find an element by class name and text
var elementVisibleAndText = function(elems, innerText){
elems = document.getElementsByClassName(elems);
//if we can't even find it, we return null
//but if we do find it, we want to return a
//not null element
if (!elems || elems.length == 0){
return null;
}
//now let's look at all of the elements found by
//in elems, and see if the innerHTML matches. If it
//does then we want to return that it was found
var each;
for(each in elems){
if(elems[each].innerHTML == innerText)
return (elems[each].offsetWidth > 0 && elems[each].offsetHeight > 0) ? elems[each] : null;
}
//else return null if nothing is found in the elements
return null;
};
Check out https://theintern.github.io/leadfoot/pollUntil.html. Intern uses leadfoot - so you should have access to this functionality.
var Command = require('leadfoot/Command');
var pollUntil = require('leadfoot/helpers/pollUntil');
new Command(session)
.get('http://example.com')
.then(pollUntil('return document.getElementById("a");', 1000))
.then(function (elementA) {
// element was found
}, function (error) {
// element was not found
});
To use the function within one of your tests - you would import it using the following path:
'intern/dojo/node!leadfoot/helpers/pollUntil'
I run into this issue all the time and we used the pollUntil functionality of intern to write a few helper utilities. In our tests we use something like .then(pollUntil(util.element_visible_by_class(), ['toast_notification'], 22000))
In a separate util.js file we have
/**
* Our shared utility for unit testing
*/
define([
'intern!object',
'intern/chai!assert',
'require',
'intern/dojo/node!leadfoot/helpers/pollUntil'
], function (registerSuite, assert, require, util, pollUntil) {
return {
element_visible_by_class: function(elem) {
return function(elem) {
elem = document.getElementsByClassName(elem);
if (!elem || elem.length == 0) { return null; }
elem = elem[0];
return (elem.offsetWidth > 0 && elem.offsetHeight > 0) ? elem : null;
}
},
element_visible_by_id: function(elem) {
return function(elem) {
elem = document.getElementById(elem);
if (!elem) { return null; }
return (elem.offsetWidth > 0 && elem.offsetHeight > 0) ? elem : null;
}
},
element_hidden_by_id: function(elem) {
return function(elem) {
elem = document.getElementById(elem);
if (!elem) { return null; }
return (elem.offsetWidth > 0 && elem.offsetHeight > 0) ? null : elem;
}
},
element_hidden_by_class: function(elem) {
return function(elem) {
elem = document.getElementsByClassName(elem);
if (!elem || elem.length == 0) { return null; }
elem = elem[0];
return (elem.offsetWidth > 0 && elem.offsetHeight > 0) ? null : elem;
}
},
}
})
I have created a custom layout and i planned to hide products only for those custom layout assigned pages.
Is there any way to get current layout id ?
For example, Let's say my custom layout_id is 10, I planned to use some looping like below to hide/show products
if (current_layout_id != 10) {
// Display products
}else {
// Hide Products
}
find layout id of current displayed module page
if (isset($this->request->get['route'])) {
$route = $this->request->get['route'];
} else {
$route = 'common/home';
}
$layout_id = 0;
if (substr($route, 0, 16) == 'product/category' && isset($this->request->get['path'])) {
$path = explode('_', (string)$this->request->get['path']);
$layout_id = $this->model_catalog_category->getCategoryLayoutId(end($path));
}
if (substr($route, 0, 16) == 'product/product' && isset($this->request->get['product_id'])) {
$layout_id = $this->model_catalog_product->getProductLayoutId($this->request->get['product_id']);
}
if (substr($route, 0, 16) == 'product/information' && isset($this->request->get['information_id'])) {
$layout_id = $this->model_catalog_information->getInformationLayoutId($this->request->get['information_id']);
}
if (!$layout_id) { $layout_id = $this->model_design_layout->getLayout($route); }
if (!$layout_id) { $layout_id = $this->config->get('config_layout_id'); }
end of layout id finding

The solution is that I have to check, if the string-values are empty strings and in this case to set null. On this way, all is working.
I'm trying to create a simple chrome extension using the following google RSS reader sample,
http://code.google.com/chrome/extensions/samples.html#597015d3bcce3da693b02314afd607bec4f55291
I can add links in the pop-up window that open tabs, but not from the feeds themselves.
Looping through the items in the feed, grabbing title tags and link tags, I want the title to link the the appropriate sites
var entries = doc.getElementsByTagName('item');
var count = Math.min(entries.length, maxFeedItems);
for (var i = 0; i < count; i++) {
item = entries.item(i);
// Grab the title for the feed item.
var itemTitle = item.getElementsByTagName('title')[0];
if (itemTitle) {
itemTitle = itemTitle.textContent;
} else {
itemTitle = "Unknown title";
}
// Grab the link for this feed item
var itemLink = item.getElementsByTagName('link')[0];
if (itemLink) {
itemLink = itemLink.textContent;
} else {
itemLink = "Unknown link";
}
var title = document.createElement("a");
title.className = "item_title";
title.innerText = itemTitle; //display title in iframe
title.addEventListener("click", titleLink); // should open link when clicking on title, but does not.
}
// -------------------------------------------------------------------
// Show |url| in a new tab.
function showUrl(url) {
// Only allow http and https URLs.
if (url.indexOf("http:") != 0 && url.indexOf("https:") != 0) {
return;
}
chrome.tabs.create({url: url});
}
function moreStories(event) {
showUrl(moreStoriesUrl);
}
function titleLink(event) {
showUrl(itemLink);
}
Any thoughts on why this is not working.
If I replace title.addEventListener("click", titleLink); with title.addEventListener("click", moreStories); each title will link to moreStories, I cannot get each title to link to itemLink.
Thanks
Its a bit hard to answer your question without the whole code, but Ill give it a shot ;)
First up, titleLink() isnt going to work because itemLink isnt known. When you create title (the link) you should of attached it to that...say title.href=itemLink then in tiltleLinks you could access that href with showUrl(event.currentTarget.href)
Also did you fix the error in that example?...if not then change frameLoaded to....
function frameLoaded() {
var links = document.getElementsByTagName("A");
for (i = 0; i < links.length; i++) {
var clssName = links[i].className;
if (clssName != "item_title" && clssName != "open_box") {
links[i].addEventListener("click", showStory);
}
}
window.addEventListener("message", messageHandler);
}
If you still have probs could you attach the whole code so I can see what your doing and Ill give you a hand.
Thank you very much for your help.
code title.href=itemLink and code showUrl(event.currentTarget.href) was exactly what I needed.
For completeness, here is the full code,
<script id="iframe_script">
function reportHeight() {
var msg = JSON.stringify({type:"size", size:document.body.offsetHeight});
parent.postMessage(msg, "*");
}
function frameLoaded() {
var links = document.getElementsByTagName("A");
for (i = 0; i < links.length; i++) {
var class = links[i].className;
if (class != "item_title" && class != "open_box") {
links[i].addEventListener("click", showStory);
}
}
window.addEventListener("message", messageHandler);
}
function showStory(event) {
var href = event.currentTarget.href;
parent.postMessage(JSON.stringify({type:"show", url:href}), "*");
event.preventDefault();
}
function messageHandler(event) {
reportHeight();
}
