Search filter by data

I try to filter data by using jQuery/HTML selector like

$("li[data-filter*='keyword']")

But this cannot filter and get same result "keyword1 keyword2" and "keyword2 keyword1" , Do you understand ?

I will give you demo..

HTML :

<input>

<li data-filter="apple pie gummi bears gummi bears john">
    Apple pie gummi bears gummi bears John
</li>

<li data-filter="oat cake chocolate bar chupa chups dessert tootsie">
    Oat cake chocolate bar chupa chups dessert tootsie
</li>
<li data-filter="jujubes cookie sugar plum lemon drops candy">
    Jujubes cookie sugar plum lemon drops candy
</li>

jQuery :

var filter_timer;
$("input").keypress(function() {
    clearTimeout(filter_timer);
    filter_timer=setTimeout(function(){
        filter();
    },500);
});

function filter() {

var keyword = $("input").val();

if($("li[data-filter*='"+keyword+"']").length) {
    $("li").animate({opacity:0.4}).css({"text-decoration":"line-through"});
    $("li[data-filter*='"+keyword+"']").animate({opacity:1}).css({"text-decoration":"blink"});
}else{
    $("li").animate({opacity:1},function(){$("li").removeAttr("style")});}
}

What you're trying to do can't be accomplished with attribute selectors. [data-filter*="apple pie"] matches only elements whose data-filter attribute contains exactly the string apple pie.

You should use .filter() instead:

$("input").keypress(function() {
    var keywords = $(this).val().split(' ');

    $('li').removeClass('matched');
    $("li[data-filter]").filter(function() {
        var filters = $(this).data('filter').split(' ');

        for (var i = 0; i < keywords.length; i++) {
            var keyword = keywords[i];

            if (filters.indexOf(keyword) == -1) {
                return false;
            }
        }

        return true;
    }).addClass('matched');
});​

You could optimize this a little more by creating the filters array for each element on page load:

$("li[data-filter]").filter(function() {
    var $this = $(this);

    $this.data('filter', $this.data('filter').split(' '));
});
