finding all iframe srcs with jquery
提问by Martin
is there a way, with jquery, to for exapmle on click, find all iframe elements, remove their src= tag, and give it back? sort of, refresh :)
有没有办法，使用 jquery，例如单击时，找到所有 iframe 元素，删除它们的 src= 标记，然后将其返回？有点，刷新:)
Was looking for foreach function or something like that, but I'M rather hopeless at this :(
正在寻找 foreach 函数或类似的东西，但我对此很无望:(
Thanks for your time, Mart

$(document).ready(function() {
$('#somebuttonid').click(function() {
$("iframe").each(function() {
var src = $(this).attr('src');
$(this).attr('src', src);
});
});
});

You can pass a function to .attr()[docs](or .prop()[docs]):
您可以将函数传递给.attr()[docs]（或.prop()[docs]）：
$('iframe').attr('src', function(index, val) {
return val;
});
This function is executed for each element. It's a bit more concise than using an explicit .eachloop.
该函数针对每个元素执行。它比使用显式.each循环更简洁一些。

You don't even need jQuery:
你甚至不需要 jQuery：
for(var i = 0; i < frames.length; i++) {
frames[i].src = frames[i].src;
}
