jquery 1.4.1 change() on textarea 在 IE 8 中不起作用

所以我的jquery（1.4.1）代码是这样的：

$(document).ready(function () {  
    $("#Pattern").focus();  
    $("textarea").change(function () { Match(); });  
    ...  
    var Match = function () {
             ...
          };  
  })

Pattern是一个textarea。所有地方都工作正常 - 除了 IE 8。而且 IE 8 的行为很奇怪 - 它有时第一次不起作用，后来似乎可以工作。我所说的不起作用是指当我在文本区域中键入内容并失去焦点时 - 不会调用匹配函数。我环顾四周，但我所有的努力都是徒劳的。

编辑：解决方案

所以，没有任何效果，我必须使用 .focusout 事件手动完成

    var previousPattern = '';
    $(document).ready(function () {
        $("#Pattern").focus();
        $("#Pattern").focusout(
                function () {
                   if ($("#Pattern").val() != previousPattern) {
                      previousPattern = $("#Pattern").val();
                      Match();
                   }
                });
       ...
    }

，现在它按预期工作。

原文

So my jquery (1.4.1) code is something like this:

$(document).ready(function () {  
    $("#Pattern").focus();  
    $("textarea").change(function () { Match(); });  
    ...  
    var Match = function () {
             ...
          };  
  })

Pattern is a textarea.
And all works fine everywhere - except IE 8. And behavior of IE 8 is weird - it doesn't work sometimes for the first time and seems to work later. By not working I mean when I type something in textarea and lose focus - Match function is not called.
I looked around but all I tried was in vain.

EDIT: solution

So, nothing worked and I had to do it by hand using .focusout event

    var previousPattern = '';
    $(document).ready(function () {
        $("#Pattern").focus();
        $("#Pattern").focusout(
                function () {
                   if ($("#Pattern").val() != previousPattern) {
                      previousPattern = $("#Pattern").val();
                      Match();
                   }
                });
       ...
    }

And now it works as expected.
