Asking about get text and replace text in Javascript

Hello

Im still learning a little Javascript language but after failed to install this add-on to my site, I came up with an idea.

For example I have a hyperlink text

Code:

<a id="xyz" href="/profile?friend='ABC'&mode=editprofile&page_profil=friendsfoes"><img src="/smiley.png" /></a>

I wanna write a script that can get and return text from link, then replace 'ABC' by text I just get.

Code:

var getname = '{postrow.displayed.POSTER_NAME}'; // <a href="http://domain.com/u1">Volunteer</a>
var gettext = getname.text; // return Volunteer
var result = replace(/'ABC'/gi, "gettext");


Why do I must use a variable?
- Cuz '{postrow.displayed.POSTER_NAME}' will only work in viewtopic_body template and return a text with link included itself. Example : https://help.forumotion.com/u1, not a simple text.

So my complete hyperlink html code will be like this

Code:

<a id="xyz" href="/profile?friend=Volunteer&mode=editprofile&page_profil=friendsfoes"><img src="/smiley.png" /></a>

I would appreciate any help.
Thank you for reading.

Thank you for your quick respond! Could you tell me the way how this script works?

He used the string's replace method with regular expressions.

In the example below, I will replace all digits with

Code:  [D]

:

Code:

var str = 'I can count from 1 to 10.';

str = str.replace(/\d/g, ' [D] ');

console.log(str); // I can count from  [D]  to  [D]  [D] .

... And so on:

Code:

var str = 'I can count from  [D]  to  [D]  [D] .';

str = str.replace(/\s\[D\]\s/gi, function () {
  return Math.floor(Math.random() * 20);
});

console.log(str); // I can count from 14 to 193.
                  // The numbers are ramdom!
