Hi All,
Relatively new to jQuery, and loving it so far. Hopefully you can help
me with this one...
I have a "quote page", which has "line items" that fetch various pieces
of info (via ajax) from the server as the user starts "drilling down".
There are a variable number of "line items", of 4 different types. I
have the code to create a new line item of a given type whenever the
user selects that type from a selection box.
Let's say one of the "line items" looks like this:
Type: <select box: ceramic or metal>
Material: <filled by ajax, depending on selection above>
Description: <filled by ajax, depending on material selected>
Quantity: <standard input field>
I've got the code to insert the HTML necessary for the above working so
far. Only big problem here was generating a "unique id field" for the
fields, which I did by having a JavaScript global "item count", which is
incremented every time a new line item is added, and which is appended
to each field ID, ie type_1, material_1, desc_1, qty_1, etc. When they
create a second line item (of any type) it's fields are appended with
_2, etc.
OK, now I have to "activate" the type_1 field, so that on a change,
it will fire off an ajax request to fetch the desired list of materials
for that "type" and fill in the (currently empty) material <div>.
Is this possible?
I *think* that I can do something like:
$("#type_1").change(function() {
var type = $("#type_1").val();
$.post("/ajax/get_material_list.php", {type:type}, function(xml) {
... function body to process the xml results here...
)};
)};
except, of course that "#type_1" above needs to be a Javascript variable
string, rather than a constant. Of course, the function body for
fetching the results must also "enable" an ajax call on a change to the
(new) material selection field, to fetch the description.
Am I even close to on the right track, or is there a better way to do
this? Should I be generating the html on the server, with the
Javascript, and passing it back, instead of generating the html with
jQuery in the client? ANY suggestions would be welcomed!
