Jquery remove text from span

Question

I\'m new to JQuery and really struggling how to perform the query I want.

I\'m using SharePoint, and the when using the External Data Column and set it to required field

Answer 1

Here's more optimised and faster approach:

$(".ms-usereditor span[class^='ms-error']:contains('External Data')").hide()

And additionally, this syntax works as a charm when you require a sort of regex pattern to find all matching nodes or nodes with similar classnames. Suppose, you need to find something .ms-error-1 .ms-error-abc. So, same syntax works and even better you could do like this:

$(".ms-usereditor span[class^='ms-error-']:contains('External Data')").hide()
