javascript

JS replaces all characters in a string instead of the first

Sometimes when replacing a string with JS, replyText= replytext.replace (“aa”,"");

This can only replace the first aa in the string, sometimes need to replace the whole aa, this method is not used.

The following methods can be used for reference:


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

ReallyDo is the replacement

ReplaceWith is what you replaceWith.

Var replyText = ”< P> To be respectfully respectfully < / p> < P> < Br / > < / p> < P> To be respectfully respectfully to be respectfully respectfully < / p> < P> < Br / > < / p>” ;

Eg:


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

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

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

You can get

“With all due respect. With all due respect. With all due respect.”
