Readme
Arg.js gives you quick and easy access to parameters in the URL.
&&&&
Arg.query()
in IE 8 #19hasOwnProperty
when looping though argumentsArg(key)
shorter interface as well as Arg.get(key)
.Arg.coerceMode = false
Arg.url(path, params, anchorString)
(i.e. no longer assumes they're variables if it's a string)The examples here assume this path:
page.html?name=Mat&address[0].city=London&address[0].country=UK&address[1].city=Boulder&address[1].country=US#?fromhash=true
Arg("name")
//= "Mat"
It will get the value from both the query segment, and the hash segment.
Arg("fromhash")
//= "true"
Arg("address")
//= [
// { city: "London", country: "UK" },
// { city: "Boulder", country: "US" }
// ]
Arg("address[0]")
//= { city: "London", country: "UK" }
Arg("address[0].city")
//= "London"
Arg("address[0].something", "Unknown")
//= "Unknown"
Arg.all()
Arg.all()
//= {
// address: [
// { city: "London", country: "UK" },
// { city: "Boulder", country: "US" }
// ],
// fromhash: "true",
// name: "Mat"
// }
Arg.all()
gets all parameters (from the query and hash segments) in one object. Optionally, you can use the query
or hash
methods to be specific.Arg.query()
Arg.query()
gets an object made up of all the values in the query segment of the URL. The query segment is everything following the initial ?
, but before the #
(if there is one.)
Arg.query()
//= {
// address: [
// { city: "London", country: "UK" },
// { city: "Boulder", country: "US" }
// ],
// name: "Mat"
// }
fromhash
value is missing.Arg.hash()
Arg.hash()
gets an object made up of all the values in the hash segment of the URL. The hash segment is anything following the #
.
Arg.hash()
//= {
// fromhash: "true"
// }
Arg.parse()
Instead of using the current URL, you can be explicit by using the Arg.parse
method.
var myArgs = "name=Mat&company=Stretchr";
Arg.parse(myArgs);
//= {
// name: "Mat",
// company: "Stretchr"
// }
Arg.url()
helperThe Arg.url()
function builds a URL, and has a few overloaded versions.
Arg.url(params)
- just the paramsPassing just an object will generate a URL based on the current location, just changing the parameters.
Arg.url({name: "Mat", company: "Stretchr"});
//= "path/to/current/page?name=Mat&company=Stretchr"
If you set Arg.urlUseHash = true
, then the parameters will be placed in the hash segment of the new URL following the #?
seperator:
Arg.urlUseHash = true;
Arg.url({name: "Mat", company: "Stretchr"});
//= "path/to/current/page#?name=Mat&company=Stretchr"
Arg.url(path, params)
- explicit pathBeing explicit about a path in the first argument will use that location instead.
Arg.url("http://www.stretchr.com/", {name: "Mat", company: "Stretchr"});
//= "http://www.stretchr.com/?name=Mat&company=Stretchr"
Arg.url(path, query, hash)
- explicit query and hash parameters in one URLIf you want to use query and hash paremeters, pass a path and two objects.
Arg.url("http://www.stretchr.com/", {name: "Mat", company: "Stretchr"}, {comment: 123});
//= "http://www.stretchr.com/?name=Mat&company=Stretchr#?comment=123";
Arg.stringify
The Arg.stringify
method lets you easily encode an object into a query string.
Arg.stringify({ name: "Mat" });
//= name=Mat
Arg.stringify({ one: { two: { three: 3 }}});
//= one.two.three=3
Arg.stringify({list:["one","two","three"]});
//= list[0]=one&list[1]=two&list[2]=three
