Client Script remove White Space from fields

purdue · ‎05-05-2025

Hello,

I have a requirement to remove whitespace from Asset tag and Serial Number on Alm_asset via Client Script. I was given regex

cleanedName = cleanedName.replace(/^\u200B+/, '').replace(/\u200B+$/, '');

Any assistance is appreciated.

function onSubmit() {

var tag = g_form.getValue('asset_tag');

if(tag != '') {

var trimmedValue = tag.replace(/\u200B+$/, '');

tag = trimmedValue;

}

@purdue

you should use onChange client script rather than onSubmit script

something like this in onSubmit if you still require that

function onSubmit() {
    // Get the values of the asset_tag and serial_number fields
    var assetTag = g_form.getValue('asset_tag');
    var serialNumber = g_form.getValue('serial_number');

    // Check if asset_tag is not empty and trim whitespace
    if (assetTag != '') {
        var trimmedAssetTag = assetTag.replace(/^\s+|\s+$/g, '');
        g_form.setValue('asset_tag', trimmedAssetTag);
    }

    // Check if serial_number is not empty and trim whitespace
    if (serialNumber != '') {
        var trimmedSerialNumber = serialNumber.replace(/^\s+|\s+$/g, '');
        g_form.setValue('serial_number', trimmedSerialNumber);
    }
}

It would be same. Create separate On change client script for both the fields as below.

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

    if (newValue != '') {
        var trimmedAssetTag = newValue.replace(/^\s+|\s+$/g, '');
        g_form.setValue('asset_tag', trimmedAssetTag);
    }

}

That's what I thought. Ok Thanks!

Hi @purdue

If your requirement is to just remove whitespaces from start and end of string then JavaScript standard TRIM function would be enough.

Here is working example:

var cleanedName="        THIS IS TEXT with WHITE SPACE AT START and END     ";
gs.print("Before:"+cleanedName);
var result =cleanedName.trim();
gs.print("After:"+result);
