Show Conditional Error On A Submission Page If Entered Data Is Less Than A ...

[Master]

How can I show an error message if the amount entered in a submission page is less than a certain value?

[pavitra2410]

Just add the following JavaScript in a footer of the submission form to validate for that field. Replace XXX with your value.

 

<script>

var num=XXX;

function chk_num(){

var mynum = document.getElementById('InsertRecordFIELDNAME').value;

if ( mynum < num ) {

alert('Enter your message here');

return false;

}

}

document.getElementById('caspioform').onsubmit=chk_num;

</script>

Thank you CaspioEnthusiast!

 

Basically we can use "return false;" to prevent form from being submitted

I tried using this method today (mynum > num (instead of mynum < num)) but I came across the following problem. 

Instead of defining var num as a predifined number, I want to use an authentication field. Depending on this field var num will be 100/1000/1500. When I test this and enter a number higher than the limitation it gives me the error message, but when I fill in a lower number (after the error message) it will give me the same message. When I submit a correct value in the first place it works perfectly. How do i fix this?

I figured it out already.

 

By using parseFloat(document.getElementById("cbParamVirtual2").value) i was able to compare it to my authentication field, which i put into Virtual2.
