I want to check that user has fill the required fields or not on SignUP button click. But actually I don't know how to do that through JavaScript.

My asp button ID's are username, password, email. These are mandatory fields to fill when user click on SignUp button it should check that these are fill. How can I accomplish that through javascript with asp.net.

You can use OnClientClick event as:

ASP.NET

<asp:button id="btn1" runat="server" onclick="btn1_Click" onclientclick="javascript:return fun();" xmlns:asp="#unknown" />

for this write a javascript function:

HTML

function fun1()
{
if(document.getelementbyId(''<%=btn1.ClientId%>').value==0)
alert("Please Enter jkhkjhkj";
return false;
}

if(userid.value=="")
{
alert("Please Enter UserID");
userid.focus();

C#

<script type="text/javascript">
function Validate()
{
    if(document.getElementById('<%=ddlCountry.ClientID%>').value=="0")
    {
        alert('Please Select Country');
        return false;
    }
   else if(document.getElementById('<%=ddlState.ClientID%>').value=="0")
    {
        alert('Please Select State');
        return false;
    }
   else if(document.getElementById('<%=txtcityName.ClientID%>').value=="")
    {
        alert('Please Enter City Name');
        return false;
    }
        return true;
}
</script>

button should be like this

<asp:button id="imbBtnSubmit" runat="server" onclick="imbBtnSubmit_Click" onclientclick="javascript:return Validate();" xmlns:asp="#unknown" />

you are asking for this script i think plz check this

function Validate()
{

var test="";
    if(document.getElementById('<%=ddlCountry.ClientID%>').value=="0")
    {
        
        test="country,";
        
    }
   if(document.getElementById('<%=ddlState.ClientID%>').value=="0")
    {
    test=test+"state,";
    
    }
   if(document.getElementById('<%=txtcityName.ClientID%>').value=="")
    {
      test=test+"city,";
       
    }
    if(test=="")
    return true;
    else
    {
    if(test.length>0)
    test= test.substr(0,test.length-1);
    alert(test +" field(s) are mandatory please fill those");
    return false;
    }
           
}
