JQuery Check if Div html has a certain character

Question

I am trying to check with JQuery if a Div #id has a certain character or not.

Here's the code I'm trying:

if ($("#mydiv").html('0')) {

  alert'zero character was found';

}

The alert is not popping up.

I'm I doing it wrong?

Answer 1

尝试使用contains

$("#mydiv:contains(0)")

Answer 2

if ($("#mydiv:contains(0)")) {

  alert('zero character was found'); // do not forget also `(`

}

Answer 3

If I read your question correctly and you're looking for a div whose id contains the string 0 then this should work for you:

 if ($("div[id*='0']").length>0) {
     alert('zero character was found');
 }

Answer 4

try using native javascript

var str = $("#mydiv").text();
if (str.indexOf('0') !== -1) {
  alert('zero character was found');
}
