Posted on by zaub

Hi hope you guys are fine.

I have one html web resource and I have JAVASCRIPT in this html web resource plus I have IFrame in this html web resource as well. I have inserted this html web resource on custom entity form using web resource icon menu on main form of entity.

On Page load when i try to access IFrame like this document.getElementById("iframeid") I get IFrame control but when I try to get IFrame using Xrm.Page.ui.controls.get("iframeid") or Xrm.Page.getControl("iframeid") i always get null.

In IFrame I am loading my Canvas app, my canvas app is embeded in model driven app via iframe.

just to let you know , I have html iframe in html web resource like this

I have 3 tabs on form and iframe is on first tab which opens bydefault on page load.

I do not want to use document.getElementById because MS does not recommend it when when try to publish our app to MS app source.

Any idea what i am doing wrong using XRM api ?

1. Try either window.parent.Xrm.Page (not recommended) or parent.Xrm.Page (better, but the below may be recommended instead)
2. Use this example of getting form context first using this as a guide:
//Get the value of an option set attribute var formContext = executionContext.getFormContext(); var value = formContext.getAttribute("new_pagechooser").getValue(); var newTarget = ""; //Set the target based on the value of the option set switch (value) { case 100000001: newTarget = https://myServer/test/pageOne.aspx; break; default: newTarget = https://myServer/test/pageTwo.aspx; break; } //Get the default URL for the IFRAME, which includes the // query string parameters var IFrame = formContext.ui.controls.get("IFRAME_test"); var Url = IFrame.getSrc(); // Capture the parameters var params = Url.substr(Url.indexOf("?")); //Append the parameters to the new page URL newTarget = newTarget + params; // Use the setSrc method so that the IFRAME uses the // new page with the existing parameters IFrame.setSrc(newTarget);
use executionContext.getFormContext(); to get the context first for example.

@zaina Does using Xrm.Page.context instead work?
