Hi All, 

I have used g_form.getControl() method in client script, as it's not a best practice. If there is any alternative for DOM manipulation, reply back on the post. It will be really helpful.

 

Thank you!

@prerna_pandey According to ServiceNow best practices

 

"Avoid Document Object Model (DOM) manipulation if possible. It can cause a maintainability issue when the instance is updated. when using DOM manipulation methods, you have to reference an element in the DOM by id or using a CSS selector. When referencing out-of-box DOM elements, there is a risk that the element ID or placement within the DOM could change thus causing the code to stop working and/or generate errors."

Hence there is no good/bad approach when it comes to DOM manipulations. It is not recommend to do DOM manipulations at all in ServiceNow.
