[JavaScript]Accessing Iframe with IE/FireFox

Grumble!


Trying to set the contents of a hidden input field of a form inside an iframe to the value of a textbox. In IE I have to use,
document.frames[0].document.forms[0].sender.value = document.getElementById('txtName').value;

Which doesn't work in FireFox, but for the FireFox method to work I have to do,

document.getElementById('sendmessage').contentDocument.frmSend.sender.value = document.getElementById('txtName').value

Which doesn't work in IE.

Is there a right or wrong method or something else I've completely missed here?

Different browsers, different methods. You have to perform a check for the browser before calling the code. You can check for document.all or document.layers.

Is it possible to do something like,

if(navigator.appName == "IE") {
include 'externaliescript.js';
} else {
include 'scriptthatworksforeveryoneelse.js';
}

Atm, all I can find is importing using the <script> tag which means I can't really deliver the different .JS files.

Edit: Ahh ok, I can just do document.write to include the file. :thumb:
