Bootstrap get glyphicon code

Question

My task is to get code from bootstrap glyphicon element (for example "\\e020").

I've tried the following approach:

html:

<div id="glyph" class="glyphicon glyphicon-trash"></div>

js:

$( document ).ready(function() {
    console.log(window.getComputedStyle($('#glyph')[0], ':before').content);
});

but here I can achieve only the character itself, not the original code.

Is there a way to get the string of "\\e020"?

Answer 1

You can use toString method with 16 parameter to transform char to HEX:

var content = window.getComputedStyle($('#glyph')[0], ':before').content
var result = '\\' + content.charCodeAt(1).toString(16);    
alert(result);
