Unable to replace text Using Jquery

Question

I have an iframecode . There is a [UID] word. I want that word to be replaced with my desired word.

<iframe class="ofrss" src="https://wall.superrewards.com/super/offers?h=asacgrgerger&uid=[UID]" frameborder="0" width="100%" height="550px"></iframe>

I want to pass the UID from jquery .

$("body:contains('UID')").html('15');

But this code doesn't give me the exact thing I want. It's not replacing the UID with 15

Answer 1

:contains looks within the text of the DOM, not attributes.

To do what you require you can use prop() or attr(), like this:

$('iframe.ofrss').prop('src', function(i, src) {
 return src.replace('[UID]', '15');
});

One thing to note here is that changing the src after the DOM loads will cause the iframe to be reloaded.
