JS replaces characters in strings that replace all instead of the first one

Sometimes when replacing strings with JS, replyText= replyText.replace("aa","");

In this way, you can only replace the first aa in the string. Sometimes you need to replace all aa, and this method cannot be used. .

You can use the following methods as reference:

The code copy is as follows:

function del_html_tags(str,reallyDo,replaceWith) {

var e=new RegExp(reallyDo,"g");

words = str.replace(e, replaceWith);

return words;

}

str is the target string

Who is reallyDo to replace

What is replaceWith replaced?

var replyText="<p>Respectful and respectful</p><p><br /></p><p>Respectful and respectful</p><p><br /></p><p>Respectful and respectful</p><p><br /></p>";

eg:

The code copy is as follows:

replyText= del_html_tags(replyText,"<br />"," ");

replyText= del_html_tags(replyText,"<p>","");

replyText= del_html_tags(replyText,"</p>","");

You can get it

"Respectful and respectful and respectful and respectful"
