Replace characters [duplicate]

This post may seem duplicated, but I have tried several ways and the problem is not solved.

I have a DataTable in which I dynamically load HTML tags.

These labels, instead of being like this:

<img src="ruta" />

they look like this:

&lt;img  src="ruta"/&gt;

I have made a jquery script that replaces the characters < and > with < and > respectively.

The problem is that only the first appearance replaces me, leaving a message like this:

 <img  src="ruta"/> &lt;img  src="ruta"/&gt; &lt;img  src="ruta"/&gt; &lt;img  src="ruta"/&gt;

My Jquery code is as follows

$(".message").each(function(){
            var $this = $(this);
            var t = $this[0].innerHTML;
            $this.html(t.replace('&lt;','<').replace('&gt;', '>'));
        });

My HTML looks like this:

<div class="message">&lt;img  src="ruta"/&gt; &lt;img  src="ruta"/&gt; </div>

That div is part of a row of a datatable.

How could I make Datatable render the HTML tags or have JQUERY replace the characters in ALL the messages instead of just the first one.

Thank you.

You have almost done it, what you were missing was to use a regular expression with the global modifier ( g )

const original='&lt;img  src="ruta"/&gt; &lt;img  src="ruta"/&gt; ';

const cambiado=original.replace(/&lt;/g,'<').replace(/&gt;/g,'>');
console.log(cambiado)

Small explanation: The replace method supports as a first parameter a string causing the substitution of the first match or a regular expression. In the case of regular expression, you can define certain modifiers.

Here is an example:

const miExpReg= /a/gi;

console.log('Aquí hay letras mAyúsculas y minúsculas'.replace(miExpReg,'_'));

g - > global ( all matches ) i - > ignore uppercase / lowercase
