[jQuery] Cascade plugin help
I am new to jquery and I need to make a form that allows a user to
select a state and a city that they go to school in. I am using the
cascade juqery plug-in (http://plugins.jquery.com/project/cascade.
Which I think is a great plugin) The problem is there is a lot of data
and it takes a long time for it all to load (some 28,000 records).
What I want to do is split it up into different files and then load
only the file that contains the data for that start/region. A sample
of my code is blow:
My html:
<div class="container-1">
<label for="rsvp_state">State</label>
<select id="rsvp_state">
<option value="">Pick a State</option>
<option value="OR">Oregon</option>
<option value="WA">Washington</option>
<option value="CA">California</option>
</select>
</div>
<div class="container-2">
<label for="rsvp_city">Pick a City</label>
<select id="rsvp_city">
</select>
</div>
//below are the different loads that contain different data based on
the state
var OR = {
ajax: {url: ‘orData.js' },
template: commonTemplate,
match: commonMatch
};
var WA = {
ajax: {url: ‘waData.js' },
template: commonTemplate,
match: commonMatch
};
var opts = {
ajax: {url: ‘otherData.js' },
template: commonTemplate,
match: commonMatch
};
$(document).ready(function() {
var currentState;
// #rsvp_state refers to a dropdown menu that contains all the states
//what I want to do with this is determine what state is currently //
selected and store that in a variable
$('#rsvp_state').change(function(){currentState = $
('#rsvp_state').val();});
jQuery(".container-2 select").each(function() {
var child = jQuery(this);
child.parents(".container-2:first").siblings(".container-1").find
("select").each(function() {
//below I want to compare the verable to the different options I have
above
if(currentState == 'OR'){
child.cascade(jQuery(this),OR);
}
if(currentState == 'WA'){
child.cascade(jQuery(this),WA);
}
else{
child.cascade(jQuery(this),opts);
}
});
});
//below is a sample line from orData.js
{'When':'Portland','Value':'123','Text':'Benson Highschool'}]
Any help is greatly appreciated.
