How to solve this problem??

The idea is that we use the regular match to the so-called space, and then replace the null character, we need to use the STR's replace API

The code is as follows:

1 <!DOCTYPE HTML>2 <HTMLLang= "en">3 <Head>4     <MetaCharSet= "UTF-8">5     <title>Document</title>6 </Head>7 <Body>8     <Script>9         //remove spaces at the beginning and end of a stringTen         functiondelate (str) { One             //match the space to the beginning, and then replace it with a blank, returning a new string str1 A Let str1=Str.replace (/\s+$/,"');  -             //back to str2 -              the Let str2=Str1.replace (/^\s+/,"') -             returnstr2; -         } - Console.log (Delate ('text')); + Console.log ('text'); -     </Script> + </Body> A </HTML>

Note: Replace is replaced by the previous one, and then the null character is replaced with \s, and then with what starts with ^.
