sLimit special characters and spaces

[Arka Banerjee]

Hi Team,

Suppose I have a single line text field on a ritm. How to limit special characters and spaces input on that so that it accepts only numbers and alphabets

Hi @Arka Banerjee 

Can you give the following a try-

^[a-zA-Z0-9]*$

Regards,

This just limits special characters, not spaces

Hi @Arka Banerjee 

Strange as the same is working in background script. 

var pattern = /^[a-zA-Z0-9]*$/;
var testStrings = [
    "HelloWorld123", // Should match
    "12345", // Should match
    "Test String", // Should not match (contains a space)
    "Special!Char", // Should not match (contains a special character)
    "Another_Test" // Should not match (contains an underscore)
];

for (var i = 0; i < testStrings.length; i++) {
    var inputString = testStrings[i];
    var isMatch = pattern.test(inputString);
    gs.info("Input String: " + inputString + ", Matched: " + isMatch);
}

Please mark my answer helpful and correct.

Regards,

Amit

Hi @Arka Banerjee ,

An alternative is - you can use OnChange client script on Requested Item table for the particular field which you are looking at and apply this script.

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue === '') {
return;
}

// Regular expression to match only numbers and alphabets
var regex = /^[A-Za-z0-9]+$/;

if (!newValue.match(regex)) {
alert("Please enter only numbers and alphabets.");
g_form.setValue(control.name, oldValue); // Reset the field value to the old value
}
}
