Getting SyntaxError: Invalid regular expression error on a field with an OnChange Client Script

[JLaue1]

Hello - 

I have a string field that I am using for a rate percentage and I am using a Client Script to ensure that the field value has a decimal with 2 numbers to the right of the decimal.  I have done something similar on a catalog variable string field and it works there, but I cannot get it to work on non-catalog form on a custom table.  

Here is my OnChange client script on the effective_tax_rate_st field:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    
    var nbrwn = g_form.getValue('effective_tax_rate_st').replace(/,/g, '.');        
    
    // Check if it is a valid value    
    
    if (isNaN(nbrwn) == true) {
        
        // If not, alert the user and blank the field value
        
        alert("This field must contain a number with maximum 2 decimals separated by a period");        
        g_form.setValue('warehouse_commissions_rate', '');        
    }    
    
    else{
        
        // Set the field value with the number of decimals required        
        
        nbrwn = parseFloat(nbrwn);
        nbrwn = nbrwn.toFixed(2);        
        g_form.setValue('effective_tax_rate_st', nbrwn);        
    }    
}

After putting any type of value in there and then leaving the field, I get the following error:

onChange script error: RangeError: Maximum call stack size exceeded function () { [native code] }

Essentially, I am trying to create a 'percentage' field, so if there is a better approach, please advise.

Any help/guidance is appreciated!

Thanks!!

Hi,

Since you are using custom table does your field name starts with u_?

Validate the field names with actual field name in custom table

You can also try regex replace(/\,/g, '.')

Thank you,

Hello - thanks for your response.  Yes, the field name is correct, it is a field on a custom table, not a custom field on a platform table.  

I'll try the regex change and see if that helps.

Thanks.
