Use regular expression to remove all html tags and keep only text

If the backend returns the content in the rich text editor to the front end, you can use this method to retain only the text.

There are several formats for labels

1.<div class="test"></div>

2.<img />

3. Custom tags<My-Tag></My-Tag>

For the above tags, the regular rules determined are reg=/<\/?.+?\/?>/g

<Denote angle brackets

The first \/? indicates the situation of this tag </div>

.+? means that everything in the middle is replaced

The second \/? means <img/>

/g means global replacement

The code is as follows:

&lt;!DOCTYPE html&gt;
&lt;html lang="en"&gt;
&lt;head&gt;
  &lt;meta charset="UTF-8"&gt;
  &lt;title&gt;Remove all tags&lt;/title&gt;
&lt;/head&gt;
&lt;script&gt;
  function matchReg(str){
    let reg=/&lt;\/?.+?\/?&gt;/g;
    ((reg,''));
  }
  matchReg(`&lt;p&gt;Remove allhtmlLabel,&lt;img/&gt;&lt;My-Tag class="abc" value="test"&gt;自定义Label也可以去除哦&lt;/My-Tag&gt;&lt;/p&gt;`);
&lt;/script&gt;
&lt;body&gt;
&lt;/body&gt;
&lt;/html&gt;
