Javascript验证在usercontrol中无效 [英] Javascript validation is not working inside usercontrol

问题描述

我正在尝试在UserControl中实现JavaScript验证&在另一个.aspx页面中调用那个UserControl



我尝试过：



Valiate.js

-----------

函数ValidateCustomerName（）{< br /> 
调试器;< br /> 
 var AptName = document.forms [form1] [count_txtAptName];< br /> 
 // var AptName = document.forms [ form1] [txtAptName];< br /> 
 var lblAptName = document.getElementById（'<％= WebForm1.FindControl（Label1）。ClientID％>'）// document.getElementById （'<％= Label1.ClientID％>'）; // document.getElementById（count_Label1）; //< br /> 
 if（AptName.value.length == 0）{< ; br /> 
 AptName.focus（）;< br /> 
 lblAptName.innerHTML =请填写申请人姓名2;< br /> 
返回false;< br / > 
}< br /> 
 else if（！AptName.value.match（/ ^ [A-Za-z] + $ /））{< br /> 
 AptName .focus（）;< br /> 
 lblAptName.innerHTML =申请人姓名续ain only alphabet2;< br /> 
返回false;< br /> 
}< br /> 
 else {< br /> 
 lblAptName.innerHTML =;< br /> 
}< br /> 
}< br /> 

解决方案

/））{< br />
AptName.focus（）;< br />
lblAptName.innerHTML =申请人姓名仅包含alphabet2;< br />
返回false;< br />
}< br />
else {< br />
lblAptName.innerHTML =;< br />
}< br />
}< br />

不要引用html元素，例如：



document.forms [form1] [txtAptName];



改为使用：



var txt = document.getElementById（<％= txtAptName.ClientID％>）。value;



希望这有帮助！

I Am Trying To Implement JavaScript Validation Inside a UserControl & calling That UserControl In An Another .aspx page

What I have tried:

Valiate.js
-----------

function ValidateCustomerName() {<br />
    debugger;<br />
    var AptName = document.forms["form1"]["count_txtAptName"];<br />
   // var AptName = document.forms["form1"]["txtAptName"];<br />
    var lblAptName = document.getElementById('<%=WebForm1.FindControl("Label1").ClientID %>')//document.getElementById('<%=Label1.ClientID%>');//document.getElementById("count_Label1");//<br />
    if (AptName.value.length == 0) {<br />
        AptName.focus();<br />
        lblAptName.innerHTML = "Please fill Applicant Name2";<br />
        return false;<br />
    }<br />
    else if (!AptName.value.match(/^[A-Za-z ]+$/)) {<br />
        AptName.focus();<br />
        lblAptName.innerHTML = "Applicant Name contain only alphabet2";<br />
        return false;<br />
    }<br />
    else {<br />
        lblAptName.innerHTML = "";<br />
    }<br />
}<br />

解决方案

/)) {<br /> AptName.focus();<br /> lblAptName.innerHTML = "Applicant Name contain only alphabet2";<br /> return false;<br /> }<br /> else {<br /> lblAptName.innerHTML = "";<br /> }<br /> }<br />

do not refer html elements like :

document.forms["form1"]["txtAptName"];

instead use :

var txt = document.getElementById("<%= txtAptName.ClientID %>").value;

hope this helps!
