HTML Web Resource loaded twice

Posted on by Community Member

I customized a Form in CRM by adding a web resource (HTML). On the load of the weg page, i'm calling a javascript function.

For some unknow reason, CRM is loading the web resource twice causing the Javascript function to be called twice as well. Is this a bug and is there a way to prevent that to happen?

I noticed that this behavior is only happening on a CRM Online SANDBOX instance. I tried that exact same code on different CRM (2013, 2015, 2016, Online) and thw web resource is only loaded once.

Any ideas?

Hi Yannic,

do you happen to have a javascript function registered twice on the onload event?

Or does the javascript function you use call another function that loads the resource?

Nothing is registered twice. With a break point in my web resource, i validated that the body=onload is called twice by CRM. What is strange is that this is only happening in one environment (CRM Online Sanbox). I tested the exact same thing in at least 3-4 other enviroments and the web resource is only loaded once.

body=onload?

have you tried window.onload?

probably the same result though, but could be worth a try. there's also document.onload I guess.

Hi Yannic,

one question: have you compared the form rendering methods between environments. I mean are you using turbo forms or legacy forms?

Good catch. I didn't thought of that. The "faulty" CRM is still using the Legacy Forms while i'm testing with the new form rendering.

Thanks for the hint !

I'll confirm soon if it "fixes" the issue.

So this is an old post, but I came across this recently in version 9 unified interface. Interestingly enough, the issue only happens when the resource has a self-executing function for the window.onload event. I'm not sure why this would be happening, but I hope this helps others that might be having the same issue.

onload fires twice:

<script type="text/javascript">

(window.onload = function () {

debugger;

alert("Web resource initialized");

})();

</script>

onload fires once:

<script type="text/javascript">

window.onload = function () {

alert("I'm initialized!! YAY!");

};

</script>
