从jquery / javascript中的字符串中获取特定单词

Question

I have string, for example:

$string = 'username1, username2 and username3 like this posts';

I want to get only text contains 'username' and delete everything else. So after delete it will be only 'username1 username2 username3' .

Answer 1

You can use the /username\\d/g to match the username followed by a digit which will give you the array of matched words then use join(' ') , join with a space to get the desired output:

 var string = 'username1, username2 and username3 like this posts'; var res = string.match(/username\\d+/g).join(' '); console.log(res); 

Answer 2

it will help you to get your character. var str = 'username1, username2 and username3 like this posts'.replace('username1, username2 and username3 like this posts','username') alert(str);
