Why Does My JQuery Filter Only Work Once On This Select Element?

I'm trying to filter results based on what a user selects in a select form. Here is my HTML:

Colour Options ); $("#product-multiple-1").change(function(){ var matches = $options.filter('.'+$(this).val()).clone(); $("#product-multiple-2").html(matches); }); Copy Now you can go back to the well as often as needed . Trying to hide options does not work in IE Solution 2: you are removing all elements that have a different class than the selected options value: $("#product-multiple-2").empty().html(matches); Copy the line is effectively removing all options first, then adds the ones that matched on the line before. you could instead hide everything: (approximately) $("#product-multiple-2 option").hide(); matches.show(); Copy Solution 3: When you do the first empty(), you don't have any other options any more, only the red ones. So, for example, when you run it for the first time, selecting Red on select1, you get only the red options in select 2 - FOREVER! When you run the second time, Green for example, there are no Green options in select2, so you get an empty nodelist. you should use jQuery's hide() and show(), like this: $("#product-multiple-1").change(function(){ var matches = $("#product-multiple-2 option." + $(this).val()); $("#product-multiple-2 option").not('.'+ $(this).val()).css('display', 'none'); matches.css('display', 'block')) return matches; }); Copy Solution 4: It's because you are removing the items that don't match so when you select a different colour, the items for that colour are gone. Save the originals and reload them instead like this: var productMultiple2 = $("#product-multiple-2"); productMultiple2.data('originalOptions', productMultiple2.html()); $("#product-multiple-1").change(function(){ var val = $(this).val(); productMultiple2.html(productMultiple2.data('originalOptions')); if (val !== "Choose Option") { $("#product-multiple-2 > option").filter(function() { return !$(this).is("." + val) && $(this).val() !== "Choose Option"; }).remove(); } });​ Copy http://jsfiddle.net/uazKL/5/ Fixed to not break with "Choose Option" Solution 5: The reason this is happening is because you're removing all the options from the second select tag in order to display the ones with a class that matches the first select's value. There's two (maybe more?) things you can do: You can keep a copy of the option elements in a variable and then grab the elements you want like so: var $options = $("#product-multiple-2 > option"); $("#product-multiple-1").change(function(){ var $matches = $options.filter("." + $(this).val()); $("#product-multiple-2").empty().html($matches); console.log($matches); }); Copy You can disable the options that are not available in the second select like so: $("#product-multiple-1").change(function(){ $("#product-multiple-2 > option").each(function(index, elem) { if ($(elem).is("." + $(this).val())) { elem.disabled = false; } else { elem.disabled = true; } }); console.log($matches); }); Copy Share Post a Comment for "Why Does My JQuery Filter Only Work Once On This Select Element?"
