Add the tim method to js

When I deployed my website today, I found an error in the js trim method,

My computer is win7 IE10 without any problems, so it is positioned as an IE compatibility problem.

Baidu, indeed, IE10 uses the new JS version containing the TRIM method), while IE earlier than version 9) does not use this method.

Add a method to string.

String. prototype. trim = function (){

Return this. replace (/^ \ s */, ''). replace (/\ s * $ /,'');

}
