Numeric digit restriction

[Vaka Krishna]

Hi Community,

I have a requirement where single line text field shouldn't contain more than four numeric digits and it should allow characters.

example:

Krishn12_krishn43: single line text should allow this string

Krishn123_krishn43: single line text shouldn't allow this string as it is having 5 digits.

Hi,

Please use the below script

var noChars = current.string_field_name;
var regexp = /^(?!(.*\d){6,})[a-zA-Z\d]*$/;
if(regexp.test(noChars)){

}
else{
//add error message
}

You can use below onChange client script:

var str = newValue; 
// Using match with regEx
var matches = str.replace(/[^0-9]/g, "");
if(matches.length >4){
g_form.showFieldMsg("your_field_name", "More than 4 digits","error");
g_form.clearValue("your_field_name");
}
