如何在jQuery中删除img标签的URL？

Question

I need to empty an img tag from it is own image but keeping the img tag empty on the page.

I use this code with no success. Any idea what is wrong here?

var img = $('<img id="'+ scope.elmItem +'">');
    img[0].src = '';

Answer 1

Combining jQuery object and pure JS properties in such manner can result in many things, most of them not working the way you want it... Try something like this:

$('img#'+ scope.elmItem).attr('src', '');

Or the pure JS approach:

document.getElementById(scope.elmItem).src = ''

Just stick to one and you'll be good to go.
