Javascript help (Greasemonkey Script)

[aha2095]

I'm extremely bad with javascript so I need help getting information from a HTML table that is in an iframe and turning it into a variable.

The frame is opened with JS if that could affect it.

Thankies for taking the time to read this post!

Hmmmm, if i remember correctly you can get the contents of a Frame/iFrame with window.frames..

I am going to assume the iframe has an ID of "myIframe", in the iFrame is a form with an id of "myForm" and a hidden input with the id "myInput"..

I cannot guarantee this will work, but try this..

 

var myValue = window.frames['myIframe'].document.forms['myForm'].elements['myInput'].value

 

And of course you should be able to set a value within an iFrame too.

 

window.frames['myIframe'].document.forms['myForm'].elements['myInput'].value = "Boobies";

 

Give that a try. :thumbup:

Ok, I'm confused now I thought it was in an iframe as it's the way it was always done but its just the pages being loaded with javascript on click I think (I did say I'm bad with JS right?).

So I just need to get information from a HTML table and turn it into a variable.

Okay, well the table's <td> will need ID's if you want to get the value from it.

 

<table><tr><td id="td1">Meh Value!</td></tr></table>

 

Using the ID, you can get the value as such;

 

<script type="text/javascript">
   // Get the value
   var val = document.getElementById('td1').innerHTML; // Meh Value!

   // Change the value
   document.getElementById('td1').innerHTML = 'Meh new value!';
</script>

Theres no id, but is there a battleship kind of system so it can get row and then the cell value?
