Summary of Chinese and space methods in the JavaScript filter string, javascript string

How does js filter Chinese characters or spaces in strings? There are many methods. We can use replacement and regular expressions to implement them. This article introduces two simple examples. If you are interested, refer to them.

1. javascript filter space:

function moveSpace() {var str = " abc defg";alert(str.replace(/[ ]/g, ""));}moveSpace(); 

2. Filter Chinese characters using javascript:

Var title = "string zifuchuan" var reg =/[u4E00-u9FA5]/g; var result = title. replace (reg, ''); alert (result );

3. Remove spaces at both ends of the string in javascript.

String.prototype.trim=function (){return this.replace(/(^/s*)|(/s*$)/g,'');} 

4. javascript removes the string and therefore spaces.

String.prototype.trim=function (){return this.replace(/(^/s*)|(/s*$)/g,'');}
