I want the validation message to be displayed under the text box in red color when the submit button is clicked.I added span, but it is not working....
The code is given below:

Java

function validation()
{
  var valfirst= document.getElementById("FirstName").value;
  var valsecond=document.getElementById("SecondName").value;
    
  if(valfirst == null || valfirst == "")
  {
    document.getElementById("spnFirstName").value=
    "First Name is required";
    return false;
  }
  else if (valsecond == null || valsecond == "")
  {
    document.write("Second Name is required");
    return false;
  } 
}

XML

<html>
<body>
<script type="text/javascript" src="External.js">
</script>
<form id="frm1" method="get">
First Name: <input type="textbox" id="FirstName"/>
<span id="spnFirstName" ></span>
Second Name:<input type="textbox" id="SecondName"/>
<input type="button" value="Submit" onClick="return validation()"/>
<input type="button" value="Clear"  onClick="reset()"/>

It seems you voted it a 2 which is not a good vote.
1 is the lowest, 5 - the highest.

Solution 2

Use innerHTML property to add a text to the span.

JavaScript

document.getElementById("spnFirstName").innerHTML = "some text";

And, input type should be "text" and not "textbox".

Since value is entered in a text box, Input type is Text box not text

Ankur^\m/ 13-Jan-11 5:36am

input is an HTML element. input type text is used for rendering a textbox on the browser.
Or use, ASP.NET control: <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
