Searching for multiple items from a list in a second list

I have the following code...
1. if ($("#filter_chemistry").val() != "") {
2. $("td.polymerTypel").not(":contains('" + $("#filter_chemistry").val().toLowerCase() + "')").parent().hide();
3. }
Where #filter_chemistry is a form text field, and the td's with the polymerTypel class will contain a list of items similar to st,ac,bde,va for example.
If I enter "ac" into my text box, all table rows NOT containing ac in the list will be correctly hidden, all good so far.

What I want is to be able to enter ac,va into the text box and have both of these items required, but not in any specific order or location.

I assume some sort of $("#filter_chemistry").val().split(",") will be required to create an array but it is beyond me. Can anyone help please?

Thanks.

Using URL Parameters

I am using some URL parameters in my jQuery and have come across a bug. Since JS is not my primary (or even secondary if I'm honest) language I am at a loss to know why.

I have the following function.
1. function urlParam(name){
2. var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
3. if (results == null) {
4. return null;
5. } else {
6. return results[1] || 0;
7. }
8. };
I then call this with the following lines (much reduced for debugging)...
1. var urlProduct = urlParam('product');
2. if (urlProduct != null) {
3. alert(urlProduct);
4. };
if I go to http://mysite/dir/?product=xxx then all seems to work unless the string xxx contains a lower-case a, m or p. any of these 3 letters will interrupt the string so...

"?product=123a456" will be "123"

but

"?product=123b456" will correctly return "123b456"
As far as I can tell it is only these 3 letters, upper-case works fine so 123A456 will work. It also make no diference where in the string they occur.

I assume the issue is being caused by some faulty regex, specifically in this bit...
1. '=([^&#]*)'
but can someone with more knowledge than help me fix it?
Thanks.

I have the following working line of code...
1. $("td.xlink").not(":contains('" + $("#filter_xlink").val() + "')").parent().hide();
and I need to make it case insensitive. I have tried the following
1. $("td.xlink").toLowerCase().not(":contains('" + $("#filter_xlink").val().toLowerCase() + "')").parent().hide();
and several variations with no success. Can anyone help me out?

Hiding page elements based on form "select"

Lets say I have a select in a form...
1. <select name="selector" id="selector">
2. <option value="1">Option 1</option>
3. <option value="2">Option 2</option>
4. <option value="3">Option 3</option>
5. </select>
I want to show and hide some table rows based on the option selected so that the following table...
1. <tr id="row1">Some Content</tr>
2. <tr id="row2">Some Content</tr>
3. <tr id="row3">Some Content</tr>
will only show the row corresponding to the selected option.
I know I can use $("#selector").val() to get the value of the select box but I'm not sure how to use that value to do anything useful...

Getting the value for a text string

I have the following HTML table
1. <tr><td align="right"><span class="jqSelector">1234</span></td></tr>
2. <tr><td align="right"><span class="jqSelector">4567</span></td></tr>
and separate form
1. <input type="number" id="NumberField">
I want to use something like
1. $(".jqSelector").click(function(){
2. $("#NumberField").val(this.val());
3. $("#NumberField").focus();
4. });
To set the form field to the clicked value and focus the field. As I understand it the .val() won't work here, but will anything else? Can I even select the "1234" without it being in a form field?

I have a select box with the id weekSelect having the following format...

<option value="21/01/2013|27/01/2013">2013 - 4</option>

So far I have the following jquery setting test values to two text fields.

$("#weekSelect").change( function() {
$("#startDate").val("Test 1");
$("#endDate").val("Test 2");
});

The question is how do I take the value from the selected option and put the two dates into the two text fields?
