JavaScript Test for special & html code [duplicate] html text special characters

This question already has an answer here:
Answer:1

because ▸ is actually this character

When you do $('#xxx').text() you'll get

Try doing it this way:

if ($("#xxx").text() == "▸")
     alert("hello");

From looking at the other questions linked in this one. Looks like the way to do what you're looking for is:

if ($("#xxx").text().charCodeAt() == '9656')
     alert("hello");
Answer:2

"&#9656‌;" is a that applies only to HTML and not to the Javascript. In HTML its' called an Entity, and it gets replaced with the literal character (▸). But it doesn't do this in JavaScript.

To check for the character in JavaScript, just put character in literally:

if ($("#xxx").text() == "▸")
    alert("hello");

You can get the character by copying it in your browser (select the ▸, and hit cmd-c or ctrl-c), and then pasting it in the JavaScript file.

The reason HTML uses entities is because it has some characters (like < and >) that can be parsed as actual parts of the code (try writing <text> in HTML; it won't be visible because HTML thinks you want an element); the entities allow these values to be parsed literally even when they look like code. Here is a working snippet, where the JavaScript successfully checks the contents of the element:

if ($("#xxx").text() == "▸")
    alert("hello");
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span id="xxx">&#9656;</span>
