The length property

[LAN MIND]

if (xmlhttp) {
var url = "/jsapi/";
var filters = ['location_id', 'time_id'];
for (var i=0; i<filters.length; i++) {
url += gid(filters).value + '/';
}

I see the length property a lot and I'm confused about how it works.
Here I believe it says: loop through: var i is equal to 0, if i is
less than filters.length then i plus 1.

Does the loop count the number of characters in location and based
upon the value (number) of characters assign a certain url?

No, with arrays, it returns the highest member number plus one.

var filters = ['location_id', 'time_id'];
alert(filters.length); // 2


this is the same as:

filters = new Array();
filters[0] = 'location_id';
filters[1] = 'time_id';
alert(filters.length); // 2

Read the specs and all shall be revealed.

You better read the specs.
