Assign <TD> ID to a Javascript Variable

[dlebowski]

I am using AJAX to populate a <td> value.  I want that <td> value to update a javascript variable on that same page.  Something like the example below.  Is this possible?

 

<td id="test1"</td>

<script>
var testvariable = (id ="test1")
</script>

you will want to use document.getElementById("test1") to reference the table cell, and use one of the appropriate properties for that object to access its value. it'll most likely be innerHTML that you're looking to use.

Thank you for the quick reply.  I don't think I have it right, but here is what I have.

 

var name = document.getElementById('test1').innerHTML;
document.write(name);

[akitchin]

what code are you using to populate the <td> element?

[dlebowski]

document.getElementById('test1').innerHTML = decodeURIComponent(raw.data.test1);

[akitchin]

and is that code working for you? if so, then you should have no problem assigning that innerHTML to a local variable.

[dlebowski]

So this should technically work.  Correct?  I know very little about javascript.

 

Thank you for the quick reply.  I don't think I have it right, but here is what I have.

 

var name = document.getElementById('test1').innerHTML;
document.write(name);

[akitchin]

it should - have you tried running it?

[dlebowski]

Yeah.  No luck.  I will keep working with it.  Thanks.

[akitchin]

if you're not calling that chunk of code after updating the <td> element with AJAX, then it won't have a value, because the element's innerHTML hasn't been updated yet. it would be helpful to see the whole script if you want more help.

[dlebowski]

Well, let me mess with it.  It's using AJAX Push so that complicates things for me.  Thanks again.
