PHP Preg_match_all in Javascript

Question

I've got this php code that works perfectly:

preg_match_all(
    '/<div style="display:block; float:left; height:240px; width:150px;'
    . ' text-align:center; margin:5px; overflow:hidden;">.*?'
    . '<span class="card-text">(.*?)'
    . '<span class="instruction">\((.*?)\)<\/span>/s',
  $html,
  $students,
  PREG_SET_ORDER
);

foreach($students as $student) {
  echo($student[1].",".$student[2]."<br />");
}

How would I do this in javascript? Thanks!

in javascript do you have a string with the html or are you traversing the DOM properly? If you are doing this with the DOM (what I would suggest), you would use a completely different method where you would use DOM functions like document.getElementById and parent.getElementsByTagName then loop through those results. — Jonathan Kuhn

Frankly you should not do this using JavaScript. You should not be trying to parse so much HTML using regular expressions either.

Instead you should consider looking at something like Simple HTML Dom parser

As for a JavaScript solution - JS is a DOM parser!

var student1 = document.getElementsByClassName('card-text')[0];
var student2 = document.getElementsByClassName('instruction')[0];
//echo out

A better solution would be to use jQuery, since you'll have fewer problems with DOM manipulation (its selector engine is fantastic!) see rough example here.

I'm actually using jquery for other parts of the project, thanks for the quick example, I'll take a look at it.
