To show validation on a field using Regex Expression
In this blog, I am going to show how we can display a validation on the field if the entered text is not in the required format Let’s consider a use case, We have a field name ‘DMV Initial License’ which is a single line of text field. When text is entered the Date format for this field should be MM/YYYY Let’s have a look at JavaScript where the magic is making this possible. Step 1: Regex Expression for Date in the required format MM/YYYY – date_regex = /^(0[1-9]|1[0-2])\/[/]?([0-9]{4})$/ Step 2: Below is the entire code of JS For Table/Entity Main Form customization, select ‘Form Properties’ to include JavaScript function as below, On Change of field ‘ DMV Initial License ’: oCustomerFormCustomization.checkDateFormat Note: Pass the execution context for calling the JS function. Hope this helps!!
