jquery Selector Special Character issues

Scenario: $ ("#" + AAA + ""), AAA represents a form ID

When AAA is a normal string, OK;

When the AAA contains a special symbol (EG:A.B), the object is not obtained;

Cause: The special symbol is escaped, and the ID cannot be obtained in that way.

// Does not work: $( "#some:id" ) // Works! $( "#some\\:id" ) // Does not work: $( "#some.id" ) // Works! $( "#some\\.id" )
Solve:The following function takes care of escaping these characters and places a ' # ' at the beginning of the ID string: function jq( myid ) { return "#" + myid.replace( /(:|\.|\[|\]|,)/g, "\\$1" ); }The function can be used like so:$ (JQ ("Some.id"))http://learn.jquery.com/using-jquery-core/faq/ how-do-i-select-an-element-by-an-id-that-has-characters-used-in-css-notation/
