    Hi all,

    I want to validate a form having multiple textboxes with samename using javascript to ensure that the user is entering values in all the textboxes before submitting the form. The following is my html code.

    <form method="post" action="addfeedetails.php" name="addfee" id="addfee" onSubmit="return Competetiorsfee();">
         <table align="center" style="font-size:11px" class="tblborder">
         <tr align="center">
             <td colspan="4" class="logintablehdr">Fee Details</td>
         </tr>
            <tr align="center">
                <td colspan="2">Center Name
                <select name="centername" id="centername" style="width:150px;text-align:center">
                <option value=""> ---SELECT--- </option>
                </select>
                </td>
            </tr>
            <tr><td></td></tr>
            <tr><td></td><td>Per Batch</td></tr>
            <tr>
                <td>ME</td>
                <td><input type="text" name="me" id="me" size="6"></td>
            </tr>
            <tr><td><hr></td><td><hr></td></tr>
            <tr>

            </tr>
            <tr>

    following code will give you idea about how to achieve it..

    
<html>
<head>

<script type="text/javascript">
function doValidate(fname)
{
	var e = document.getElementsByName(fname);
	for(var i = 0; i < e.length; i++)
	{
		if(e[i].value == "")
		{
			alert("Please input values");
			return;
		}
	}
	alert("all fields have some value");
}
</script>

</head>

<body>
	<input type="text" name="ip[]" value="" />
	<input type="text" name="ip[]" value="" />
	<input type="text" name="ip[]" value="" />
	<input type="button" name="Do" value="Do" onclick="doValidate('ip[]');" />
</body>
</html>
