单击按钮后，jQuery Ready功能不起作用

问题描述

我有一个JQuery Ready函数

I have a JQuery Ready function

 $(document).ready(function () {
   $('#<%= txtBlockAmount.ClientID %>').keyup(function (e) {
   $(this).val(addCommasOnKeyPress($('#<%= txtBlockAmount.ClientID %>').val()));
  });

});


function addCommasOnKeyPress(nStr) {
    nStr = nStr.replace(/\,/g, '')
    nStr += '';
    var x = nStr.split('.');
    var x1 = x[0];
    var x2 = x.length > 1 ? '.' + x[1] : '';
    var rgx = /(\d+)(\d{3})/;
    while (rgx.test(x1)) {
        x1 = x1.replace(rgx, '$1' + ',' + '$2');
    }
    return x1 + x2;
}

在页面加载时效果很好.它有一些文本框.它还具有下拉列表.当我想通过选定的下拉列表更改"加载以前的值时，它不起作用.有人知道吗?请回复.

it works nice on the page load. It has some textbox. It has also Dropdown List. When I want to Load Previous Value by Selected DropDown Change then it doesn't work. Have Anybody known?? Please Reply.

推荐答案

可能是它在回发后失去了keyup事件.最好的选择是将其绑定到.cs page_load方法中，例如

Probably, its loosing the keyup event after postback. The best bet would be to bind it in .cs page_load method, something like

txtBlockAmount.Attributes.Add("onKeyUp", "javascript:onkeyupmethod()");

您的js函数将类似于

function onkeyupmethod()
{
$('#<%=txtBlockAmount.ClientID'%>).val(addCommasOnKeyPress($('#<%= txtBlockAmount.ClientID %>').val();
}
