Jquery/Javascript regex: filter, allow multiple tags to be typed in to select that category, jsfiddle -

-

http://jsfiddle.net/nicktheandroid/atknw/

the goal take value of textbox, have multiple keywords in seperated space, filter list show item(s) contain of keywords. right now, can type keywords in listed in <span class="tags">.

i able type them in, out of order, , have still keep item keywords visible item. think might have use .split(" ") somewhere in here... hmm...

<li>entertainment     <span class="tags">tv radio dance opera</span>       </li>

jquery:

$("#filter").keyup(function () {     var filter = $(this).val(), count = 0;     var length = $(this).val().length;     if (length > 1) {         $(".filtered li").each(function () {             if ($(this).text().search(new regexp(filter, "i")) < 0) {                 $(this).addclass("hidden");             } else {                 $(this).removeclass("hidden");                 count++;             }         });     } else {         $('.filtered li').removeclass("hidden")             count++;     }     $("#filter-count").text(count); });

would know how accomplish this?

exactly suspected, you'll need use string.split() split user input, , match words one-by-one against tags.

modified code as:

$("#filter").keyup(function() {     var filter = $(this).val(),         count = 0;     var length = $(this).val().length;     if (length > 1) {         var filter_tags = filter.split(" "); // split user input spaces         $(".filtered li").each(function() {             var $this = $(this);             var matches = true;             // match each splitted string against whole tags string             $.each(filter_tags, function(i, a_filter) {                   if ($this.text().indexof(a_filter) === -1) {                     matches = false;                 }             });             if (matches) {                 $this.removeclass("hidden");                 count++;             } else {                 $this.addclass("hidden");             }         });             } else {         $('.filtered li').removeclass("hidden")         count++;     }      $("#filter-count").text(count); });

you might need pass smart regexp split allow both spaces , commas separators.
