在Textbox控件中输入用户名生成异常错误 [英] Entering Username into Textbox Control Generating Exception error

问题描述

Hello Guys

我想在Clientbox控件中显示客户端名称。数据来自数据库。但我面临的问题是每当我编辑该客户名称时

例如假设默认名称是Rajesh但如果我编辑它像< rajesh>那么它会生成异常错误位置0处没有排。现在我的方案是我想在文本框中显示可编辑的客户端名称。那么我该如何执行这项任务呢。请帮忙。谢谢













好​​的，这是我的代码：

Hello Guys

For example Suppose default name is "Rajesh" but if i edit it like " < rajesh >", It generates an exception error "There is no Row At Position 0". Now my scenario is that i want to display the client name inside textbox which is editable. So how can i perform this task. Please help. Thanks

推荐答案

(document).ready(function () {
CharCount();

(document).ready(function () { CharCount();

('#<%=txtMessageText.ClientID %>').keyup(function (e) {
CharCount();
}）;

function CharCount() {
var tbLength =

('#<%=txtMessageText.ClientID %>').keyup(function (e) { CharCount(); }); function CharCount() { var tbLength =

('#<%=txtMessageText.ClientID %>').val().length;

('#<%=txtMessageText.ClientID %>').val().length;
