Field validation restrict field length and should not allow special characters except hyphen

[sony8]

Hi 

I am working on Onchange client script.

there is a field called description.

description should not allow special character but should allow hyphen.

it should only allow length = 32 char.

below is the script i have written.

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

    var regExp = /^[a-zA-Z0-9]+$/;
    if (!regExp.test(newValue)) {
        alert("Please Enter alpha-numeric value only");
        g_form.clearValue('description');
    }


}

 how to restrict length and allow hyphen ?

Hi @sony8 
Below script can be used to fulfill your requirement.

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

    var regExp = /^[a-zA-Z0-9-]{32}$/;
    if (!regExp.test(newValue)) {
        alert("Please Enter alpha-numeric value only");
        g_form.clearValue('short_description');
    }

}

Explanation:

• ^ asserts the position at the start of the string.
• [a-zA-Z0-9-] matches any alphanumeric character or a hyphen.
• {32} ensures that the previous character set is matched exactly 32 times.
• $ asserts the position at the end of the string.

try this

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

    // Regular expression to allow alphanumeric characters and hyphens
    var regExp = /^[a-zA-Z0-9-]+$/;

    // Check if the new value matches the regular expression and has a length of 32 characters
    if (!regExp.test(newValue) || newValue.length != 32) {
        alert("Please enter an alphanumeric value with hyphens allowed, and ensure it is exactly 32 characters long.");
        g_form.clearValue('description');
    }
}
