Hi, we have a requirement to show an alert message when use enters the maximum length of the field that it is set to.

We have a multiple lines of text field and its limit we have currently set to is 5000 characters and when users reaches 5000 characters, I want to show an alert message. Please advise how can this be achieved.Thanks.

Hi James,

You could change the control of multiple lines of text field, such as change it to Rich Text Editor Control.

And if users reach 5000 characters, it will automatically alert this error message:

Hi,

Try below code

function AlertWhenLengthExceeded(executionContext)

{

Var formContext= executioncontext.getFormContext();

Var value = formContext.getAttribute("yourfieldschemanane").getValue();

if(value.length>500)

alert("your message");

}

Add this function on onchange of your field
