Question

I am trying to create a if statement that triggers a alert box if there is text in the div.

My Jsfiddle: http://jsfiddle.net/D7cPT/21/

My HTML:

<div id="post-preview">aasasdasd</div>

MY JQUERY:

$(document).ready(function() {
    // Bind it to some action.
    if{$('#post_body_html').html();) {
       alert('asdasda');
      }
});

Answer 1

OH DEAR GOD:

//why is there a bracket after the if and a semicolon in there?
if{$('#post_body_html').html();) { 

How about:

//change if{ to if( and remove semicolon
if($('#post_body_html').html()) {

Also your selector doesn’t match the ID of your element. Change #post_body_html to #post-preview

jsFiddle

Edit:

To those who land here later on, a better way to accomplish the same test is written:

if($('#post_body_html')[0].childNodes.length) {

instead.
