I have a external HTML web resource which is placed onto contact form. During the on-load event of contact form, the below statement of the code does not work ( it should alert the HTML document object)

it throws an error as below.

Unable to get property 'contentWindow' of undefined or null reference

function Contact_OnLoad() {

showHidePostalAddressWebResource();

}

Function showHidePostalAddressWebResource(){

var htmlcontent = Xrm.Page.getControl('WebResource').getObject().contentWindow.document;

alert(htmlcontent);

}

it only happens in Unified Interface not in Web Client. Can anyone please suggest any alternative statement for above code ?

Hi,

Accessing the dom object is not supported so no surprise that its not working. What exactly are you trying to achieve?

Hi ,

As Ravi already mentioned , that this is not supported. However did you tried executing below line whether object is getting or not ?

Xrm.Page.getControl('WebResource_name').contentWindow;

Thanks Ravi. I want to make invisible the HTML web resource's all the fields based on one field (SameAsAddressCheckbox) changes in contact form. See the complete javascript as below

function Contact_OnLoad() {

showHidePostalAddressWebResource();

}

function showHidePostalAddressWebResource() {

var SameAsAddressCheckbox = Xrm.Page.getAttribute("addresssameasresidential").getValue();

//access the Postal Address field

var htmlcontent = Xrm.Page.ui.controls.get('WebResource_ContactPostal').getObject().contentWindow.document;

alert(htmlcontent);

//var htmlcontent = Xrm.Page.getControl('WebResource_ContactPostal').getObject().contentWindow.document;

if (htmlcontent.getElementById("allfields") != null) {

if (SameAsAddressCheckbox) {

htmlcontent.getElementById("allfields").style.visibility = "hidden";

htmlcontent.getElementById("addline1").value = null;

}

else {

htmlcontent.getElementById("allfields").style.visibility = "visible";

}

}

else {

setTimeout(showHidePostalAddressWebResource, 500);

}

}

Hi,

why dont you put the checking (JS) inside the html, while the form field changed, call the html again, and show hide the fields in html based on the form field value. You can avoid to use unsupported code in this case.

Agree with Alex, instead of doing the show hide from crm script, perform the show hide within the HTML.

Also, it is always better to just try it with simple field and simple logic instead of building the complex logic...try that if doesn't work, share the sample code here to assist further.

Hi Ravi and Alex, The Issue is that HTML webresource is third party one and will be replaced every time when we upgrade or change the solution.
Is there no other alternative ways of doing this other than this ?

Hi,

I don't thik there is any supported way but if this is your requirement, I will see if this can be achieved. So just to confirm, you have a HTML web resource embedded in a contact form and you want to retrive the fields from that HTML using the CRM script (on load)?
