通过PHP设置ID

Question

I have the following code but it cannot be directly edited

<div class="slide-content">
<iframe src="sdsdsds" width="640" height="360" frameborder="0" title="Bing"     webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
</div>
</li>
<li class="slide" data-thumb="sdsdsdsd">
<div class="slide-content">
<iframe src="sdsdsdsd" width="640" height="360" frameborder="0" title="Walmart"     webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

</div>
</li>

I want to set IDs for the iframes so they become like so

 <iframe id="IFRAME1" src="sdsdsds" width="640" height="360" frameborder="0" title="Bing"     webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

I'm somewhat proficient in PHP but don't know how to do this; this would have to be in the code and set through some way.

Help! :-)

If you know the src= attributes, you can do this with JavaScript. I know that's not what you asked for, but I believe it'll work.

You can get a collection of iframe elements with document.getElementsByTagName('iframe'). A collection behaves like an array, so you can iterate over it. Check the src= attribute (available in the .src property), figure out the ID you want to use, and use setAttribute("id", "whatever"); to set an ID on each iframe. You can hook this to onload and the iframes will have IDs when you need them.
