Question

I want to be able to hide list items that have less than 3 characters, how do I do this? What is wrong with my code below?

I am a JavaScript/jQuery newbie.

jQuery().ready(function () {
    if (jQuery('ol li').length < 3) {
        jQuery(this).hide();
    };
});

Answer 1

Your code is saying

if (jQuery('ol li').length < 3) {  //If I have less than 3 li elements
    jQuery(this).hide();   //hide the window object
};

What you want to use is filter

$('ol li').filter( function(){ return $(this).text().length<3; } ).hide();

EDIT – Based on your comment in my post: If it is a span tag that could have other data around it:

$('ol li span').filter( function(){ return $(this).text().length<3; } ).parent().hide()

Fiddle running the span example
