使用javascript验证asp.net中的文本框时出现错误 [英] error coming while validating textboxes in asp.net using javascripts

问题描述

我将以下代码用于文本框验证.


这是我在javascript文件中定义的函数.我这样做是为了确保文本框不应为null，并且文本框应仅包含字母.

i used the following code for textbox validation..


this is the function which i defined in the javascript file.i done this to ensure the textbox should not be null and the textbox should contain only alphabets.

function RegainFocus() 
        { 
            if((document.getElementById("TextBox1").value).length == 0 || 
            (document.getElementById("TextBox2").value).length == 0 ||
            (document.getElementById("TextBox3").value).length == 0||
            !document.getElementById("TextBox1").value.match(/^[a-zA-Z]+$/)||
            !document.getElementById("TextBox2").value.match(/^[a-zA-Z]+$/)||
            !document.getElementById("TextBox3").value.match(/^[a-zA-Z]+$/)) 
             { 
               alert ("please enter a valid data");
             }            
        }

在表单加载事件中，我将javascript文件称为

in the form load event i called the javascript file as

Page.RegisterClientScriptBlock("MyScript", "<SCRIPT     Language='JavaScript' src='JScript.js'></SCRIPT>");
Button1.Attributes.Add("OnClick", "RegainFocus()");

这对我来说是引发错误....."Microsoft JScript运行时错误:必需的对象"

任何人都可以帮我做到这一点..........???

this is throwing error for me....."Microsoft JScript runtime error: Object required"

can anyone plss help me in doing this..........???
