Javascript errors when embedding a form in an iframe

asked on February 17, 2016

I'm using the embed code example found here (obviously, swapping out the generic values for my site-specific details):

<script type="text/javascript" src='FormsServerURL/Forms/js/forms-embed.js?v=9.2'></script>
<script type="text/javascript">
var title = document.getElementById('title').innerHTML;
var lf = new LaserficheForms.Form(document.getElementById('myform'), {
bpid: 'ID', host: 'FormsServerURL/Forms', params: 'Topic_Name=' + title,
onloadCallback: function () {
var s = lf.getFrmDocument().getElementsByName('action');
if (s.length > 0) {
s[0].onclick = function () {
document.getElementById('myform').style.display = 'none';
};
}
}
});
</script>;

But when I load the page I get the following javascript errors

IE 11
Object doesn't support property or method 'getFrmDocument'
Chrome
Uncaught TypeError: lf.getFrmDocument is not a function
Firefox
TypeError: lf.getFrmDocument is not a function

These errors point to the var s = lf.getFrmDocument().getElementsByName('action'); line.

What is the updated method name that allows for grabbing the action button in Laserfiche forms?

are you including this javascript file?

FormsServerURL/Forms/js/forms-embed.js

in this JS file i can see function called getFrmDocument

Yes. As mentioned, I've swapped out FormsServerURL for the actual server name on which Forms is running.

Do you use this example without javascript errors?

Nevermind. I'm a liar.

I had added .getFrm(); to the end of that sample code to experiment with adjusting the options. This certainly changed what var lf was and prevented grabbing the action button.

I further complicated the issue by using this in an iframe on a different server, so the Blocked a frame with origin ____ from accessing a cross-origin frame error got me too. But that's something completely different.

Thanks for the response. It nudged me in the right direction of actually reading what I wrote :)
