如何在Javascript中转义PHP变量？

Question

I am trying to create a Javascript function that echoes out a Wordpress function called the_title() which just returns the title of the a blog. Through PHP it echoes out fine but when I do it through Javscript, however, quotes seem to be unescaped (specifically single quotes). Any help or explanation why this is happening?

THE CODE:

function createSliderTabs() {   
    var para = document.createElement("li");
    var strings = "<?php the_title(); ?>";
    var post_string = strings.replace(/"/g, "").replace(/'/g, "").replace(/\(|\)/g, "");
    var node = document.createTextNode(post_string);
    para.appendChild(node);
    var element = document.getElementById("control-navigation");
    element.appendChild(para);
}

    createSliderTabs();

THE RESULT:
Macy&#8217 ;s Herald Square (had to include space or it would've changed to single quote)

WHAT IT SHOULD BE:
Macy's Herald Square

Any help or guidance on why this is happening? Thx in advance...

Answer 1

You can use html_entity_decode:

I'm not really familiar with wordpress, but I suppose you would use it inside the_title():

function the_title()
{
   $str = 'Macy’s Herald Square';
   echo html_entity_decode ($str, ENT_COMPAT , "UTF-8");
}

If you need to use json_encode() you should be able to do

$json = html_entity_decode(json_encode($array), ENT_COMPAT , "UTF-8");

EDIT: added ENT_COMPAT , "UTF-8"
