How to validate array input field?Please help me to solve this issue.
<form action="" method="post" name="frmPayPal1" id="frmPayPal1" onsubmit="return validateForm()"/>
<input type='text' name='txt_jobid[]' id='txt_jobid' >
<input type="submit" value="submit"/>
</form>
<script>
function validate(job)
{
if(job.elements['txt_jobid[]'].length == 0)
{
alert(" Please Enter Value!");
return false;
}
}
</script>
Maybe this...
<form action="" method="post" name="frmPayPal1" id="frmPayPal1">
<input type="text" name="txt_jobid[]" id="txt_jobid">
<input type="submit" value="submit">
</form>
<script>
$(document).ready(function(){
$('#frmPayPal1').on('submit', function(){
var lngtxt=($(this).find('input[name="txt_jobid[]"]').val()).length;
console.log(lngtxt);
if (lngtxt==0){
alert('please enter value');
return false;
}else{
//submit
}
});
});
</script>
You need to pass this
onsubmit="return validateForm(this)"
Also, return true if validation succeeds
function validate(job)
{
if(job.elements['txt_jobid[]'].length == 0)
{
alert(" Please Enter Value!");
return false;
}
return true;
}
function validateForm(){
if((document.getElementById("txt_jobid").value).length == 0){
alert(" Please Enter Value!");
return false;
}
} <form action="" method="post" name="frmPayPal1" id="frmPayPal1" onsubmit="return validateForm()">
<input type='text' name='txt_jobid[]' id='txt_jobid'>
<input type="submit" value="submit"/>
</form>Please let me know if you have any query.
