Hi dear,,

this is my first post in this forum,

I am facing an issue with the last if statement, it is being ignored ,

your kind help is highly appreciated.

<script type="text/javascript">
function ValidateMobNumber(mobno) {
var fld = document.getElementById(mobno);

if (fld.value == "") {
alert("You didn't enter a phone number.");
fld.value = "";
fld.focus();
return false;
}
if (isNaN(fld.value)) {
alert("The phone number contains illegal characters.");
fld.value = "";
fld.focus();
return false;
}
if (!(fld.value.length == 8)) {
alert("The phone number is the wrong length. \nPlease enter 8 digit mobile no.");
fld.value = "";
fld.focus();
return false;
}
if (fld.charAt(0)!="9"){
alert("Cell no should start with 9");
fld.value = "";
fld.focus();
return false;
}
}
</script>

if you are looking for an actual number, I believe you need to do something like:

Code:

if(fld.charAt(0)!==9){
//run your code.....
}

your code turns 9 into a string because you surrounded it with dbl quotes.

thank you for your quick response.

I've tried what you said but it is still having the same issue.

below is the complete code :

if (fld.value == "") {
alert("You didn't enter a phone number.");
// fld.value = "";
// fld.focus();
return false;
}
if (isNaN(fld.value)) {
alert("The phone number contains illegal characters.");
// fld.value = "";
// fld.focus();
return false;
}
if (!(fld.value.length == 8)) {
alert("The phone number is the wrong length. \nPlease enter 8 digit mobile no.");
// fld.value = "";
// fld.focus();
return false;
}
if(fld.charAt(0)!=9){
alert("Cell no should start with 9");
// fld.value = "";
// fld.focus();
return false;
}
}
</script>

You should be using fld.value.charAt(0). You need to access the value before you try and get it's first character.
