javascript - Call JSON.stringify on all pre elements -


i'm trying json.stringify json text in <pre> elements in document specified class, , use google-code-prettify add syntax colouring. since don't know javascript or jquery i'm struggling - far have following:

<body onload="prettyprint()">     ...     <pre class="prettyprint lang-js">{...}</pre>     ... </body> <script>     $('[class="prettyprint lang-js"]').next().text("test"); // call json.stringify()? </script>

the pretty-printing works, don't know how call json.stringify or select correct elements.

more specifically, want <pre> elements in document "prettyprint lang-js" class, i'd replace text content results of calling json.stringify on text, , call
google-code-prettify `prettyprint()' syntax colour it.

you can use class selector select element class name. try this.

$('.prettyprint.lang-js').each(function(){     var $this = $(this);     $this.text(json.stringify($this.text())); });  //now can call prettyprint prettyprint();
