i am trying to create array from window.location.hash variable but i am failling.
My code is:
$.each(window.location.hash.replace("#", "").split("&"), function (i, value) {
value = value.split("=");
var my_item = {value[0] : value[1]};
form_data[i] = my_item;
});
console.log(form_data);
Thanks.

Reset to default 5Give this a try:
var hash = window.location.hash.slice(1);
var array = hash.split("&");
var values, form_data = {};
for (var i = 0; i < array.length; i += 1) {
values = array[i].split("=");
form_data[values[0]] = values[1];
}
console.log(form_data);
...Of course I suspect you may be wanting the search property, rather than hash, but I don't know your specific use case.
your code is correct only error is
$.each(window.location.hash.replace("#", "").split("&"), function (i, value) {
value = value.split("=");
var _formItem={};
var my_item={};
my_item[value[0]]= value[1];
form_data[i] = my_item;
});
JavaScript doesn't support the following notation:
var my_item = {value[0] : value[1]};
Try this instead:
var my_item = {};
my_item[value[0]] = value[1];
This will create an array, where each element has a key and a value, for example:
[{name: jason}, {age: 23}, {location: pacific}] //array of single keys
Using a hash probably makes more scene in your case, so you can call form_data['age'], and won't have to look though the array:
initialize form_data to an object:
form_data = {};
Add keys directly to it:
form_data[value[0]] = value[1];
So the result is:
{name: jason, age: 23, location: pacific} //associative array with properties
To get associative array from url hash:
function readUrlHashParams() {
var result = {};
var hashParam = window.location.hash.substring(1);
var params = hashParam.split("&");
$.each(params, function (index, set) {
var paramSet = set.split("=");
if (typeof (paramSet[1]) !== "undefined") {
result[paramSet[0]] = decodeURIComponent(paramSet[1]);
} else {
result[paramSet[0]] = "";
}
});
return result;
}
Example URL
http://localhost/Index.html#Param1=test1&Param2=Test2&Param3=
Result
var test = readUrlHashParams();
console.log(test);
Object {Param1: "test1", Param2: "Test2", Param3: ""}
Undeclared form_data is not an object, so it can't have any properties, so form_data[i] = ... will fail. Run this script in a decent browser and the console should show you a message amounting to what I just said.
edit - no it won't because the bogus object literal syntax will trip it up first as Kobi mentions. Both issues should be fixed.
Here's a sample based on the following URL:
http://www.someUrl.com/Index.htm#foo=bob&moo=alice
<!DOCTYPE html>
<html lang="en">
<head>
<title>hash me long time</title>
</head>
<body>
<p>Hello World!</p>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
<script type="text/javascript">
$(function () {
var hash = window.location.hash.replace('#', '').split('&');
var myArray = new Array();
for (var x = 0; x < hash.length; x++) {
var itemArray = hash[x].split('=');
var item = new Object();
item.key = itemArray[0];
item.value = itemArray[1];
myArray.push(item);
}
for (var x = 0; x < myArray.length; x++)
console.log(myArray[x].key + ' is ' + myArray[x].value);
});
</script>
</body>
</html>
Perfect Object.
location.hash = location.hash ? location.hash : "#!";
$.each((location.hash ? location.hash.split("#!") : [""])[1].split("&"), (function () {
y = this.split("=");
$hash[y[0]] = y[1];
}));
If you are not yet using #! you can change it to #
#. The url will get read along, which I think is not what you want. – syockit Commented Aug 25, 2010 at 6:39
