Why Does This Work In Jsfiddle But Not In My Document

I found a wonderful jsfiddle that someone has made and wanted to use part of it in my project: http://jsfiddle.net/manuel/29gtu/ It works on the jsfiddle but not in my HTML documen

Solution 1:

You should wrap your whole code within $(document).ready(function() {...});

So.

<script type="text/javascript">

    $(document).ready(function() {
        $("button").click(function() {
            var id = $("#id").val();
            var text = "icon-" + id;
            // update the result array
            var result = JSON.parse(localStorage.getItem("result"));
            if (result == null) result = [];

            result.push({
                id: id,
                icon: text
            });
            // save the new result array
            localStorage.setItem("result", JSON.stringify(result));

            // append the new li
            $("#bxs").append($("<li></li>").attr("id", "item-" + id).html(text));
        });

        // on init fill the ul
        var result = JSON.parse(localStorage.getItem("result"));
        if (result != null) {
            for (var i = 0; i < result.length; i++) {
                var item = result[i];
                $("#bxs").append($("<li></li>").attr("id", "item-" + item.id).html(item.icon));
            }
        }

    });

</script>

Note

In jsfiddle onLoad mode do that for you, i.e. when you select onLoad from left side panel drop down, then all js code execute after all resources become appeared in the DOM.

Solution 2:

Put in $(document).ready like this, Also give type of script tag

<script type="text/javascript">
$(document).ready(function() {   

    $("button").click(function() {
        var id = $("#id").val();
        var text = "icon-" + id;
        // update the result array
        var result = JSON.parse(localStorage.getItem("result"));
        if (result == null) result = [];

        result.push({
            id: id,
            icon: text
        });
        // save the new result array
        localStorage.setItem("result", JSON.stringify(result));

        // append the new li
        $("#bxs").append($("<li></li>").attr("id", "item-" + id).html(text));
    });

    // on init fill the ul
    var result = JSON.parse(localStorage.getItem("result"));
    if (result != null) {
        for (var i = 0; i < result.length; i++) {
            var item = result[i];
            $("#bxs").append($("<li></li>").attr("id", "item-" + item.id).html(item.icon));
        }
    }
})​;    
 </script>
