[英]Getting values from query string in an URL using AngularJS $location
Regarding $location.search
, the docs say,关于
$location.search
,文档说,
Return search part (as object) of current url when called without any parameter.
不带任何参数调用时,返回当前 url 的搜索部分(作为对象)。
In my URL, my query string has a param ?test_user_bLzgB
without a value.在我的 URL 中,我的查询字符串有一个没有值的参数
?test_user_bLzgB
。 Also $location.search()
returns an object.另外
$location.search()
返回一个对象。 How do I get the actual text?我如何获得实际文本?
Not sure if it has changed since the accepted answer was accepted, but it is possible.不确定自接受的答案被接受以来它是否已经改变,但这是可能的。
$location.search()
will return an object of key-value pairs, the same pairs as the query string. $location.search()
将返回一个键值对对象,与查询字符串相同。 A key that has no value is just stored in the object as true.没有值的键只是作为真存储在对象中。 In this case, the object would be:
在这种情况下,对象将是:
{"test_user_bLzgB": true}
You could access this value directly with $location.search().test_user_bLzgB
您可以直接使用
$location.search().test_user_bLzgB
访问此值
Example (with larger query string): http://fiddle.jshell.net/TheSharpieOne/yHv2p/4/show/?test_user_bLzgB&somethingElse&also&something=Somethingelse示例(具有更大的查询字符串): http : //fiddle.jshell.net/TheSharpieOne/yHv2p/4/show/?test_user_bLzgB&somethingElse&also&something=Somethingelse
Note: Due to hashes (as it will go to http://fiddle.jshell.net/#/url , which would create a new fiddle), this fiddle will not work in browsers that do not support js history (will not work in IE <10)注意:由于哈希(因为它会转到http://fiddle.jshell.net/#/url ,这会创建一个新的小提琴),这个小提琴在不支持 js 历史的浏览器中不起作用(将不起作用在 IE <10)

As pointed out in the comments by @Naresh and @DavidTchepak, the $locationProvider
also needs to be configured properly: https://code.angularjs.org/1.2.23/docs/guide/$location#-location-service-configuration正如@Naresh 和@DavidTchepak 在评论中指出的那样,还需要正确配置
$locationProvider
: https ://code.angularjs.org/1.2.23/docs/guide/$location#-location-service-configuration
如果您只需要将查询字符串视为文本,则可以使用: $window.location.search
$location.search()
returns an object, consisting of the keys as variables and the values as its value. $location.search()
返回一个对象,由作为变量的键和作为其值的值组成。 So: if you write your query string like this:所以:如果你这样写你的查询字符串:
?user=test_user_bLzgB
You could easily get the text like so:你可以很容易地得到这样的文本:
$location.search().user
If you wish not to use a key, value like ?foo=bar, I suggest using a hash #test_user_bLzgB ,如果您不想使用键值,例如 ?foo=bar,我建议使用哈希 #test_user_bLzgB ,
and calling并打电话
$location.hash()
would return 'test_user_bLzgB' which is the data you wish to retrieve.将返回“test_user_bLzgB”,这是您希望检索的数据。
Additional info:附加信息:
If you used the query string method and you are getting an empty object with $location.search(), it is probably because Angular is using the hashbang strategy instead of the html5 one... To get it working, add this config to your module如果您使用了查询字符串方法,并且使用 $location.search() 获得了一个空对象,则可能是因为 Angular 使用的是 hashbang 策略而不是 html5 策略...要使其正常工作,请将此配置添加到您的模块
yourModule.config(['$locationProvider', function($locationProvider){
$locationProvider.html5Mode(true);
}]);
First make the URL format correct for getting the query string use #?q=string that works for me首先使 URL 格式正确以获取查询字符串使用对我有用的#?q=string
http://localhost/codeschool/index.php#?foo=abcd
Inject $location service into the controller将 $location 服务注入控制器
app.controller('MyController', [ '$location', function($location) {
var searchObject = $location.search();
// $location.search(); reutrn object
// searchObject = { foo = 'abcd' };
alert( searchObject.foo );
} ]);
So the out put should be abcd所以输出应该是abcd
you can use this as well你也可以使用这个
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
var queryValue = getParameterByName('test_user_bLzgB');
If your $location.search()
is not working, then make sure you have the following:如果您的
$location.search()
不起作用,请确保您具有以下内容:
1) html5Mode(true)
is configured in app's module config 1)
html5Mode(true)
在app的module config中配置
appModule.config(['$locationProvider', function($locationProvider) {
$locationProvider.html5Mode(true);
}]);
2) <base href="/">
is present in your HTML 2)
<base href="/">
存在于您的 HTML 中
<head>
<base href="/">
...
</head>
References:参考:
Angular does not support this kind of query string. Angular 不支持这种查询字符串。
The query part of the URL is supposed to be a &
-separated sequence of key-value pairs, thus perfectly interpretable as an object. URL 的查询部分应该是一个
&
分隔的键值对序列,因此可以完美地解释为一个对象。
There is no API at all to manage query strings that do not represent sets of key-value pairs.根本没有 API 来管理不代表键值对集的查询字符串。
In my NodeJS example, I have an url "localhost:8080/Lists/list1.html?x1=y" that I want to traverse and acquire values.在我的 NodeJS 示例中,我有一个 url "localhost:8080/Lists/list1.html?x1=y",我想遍历并获取值。
In order to work with $location.search() to get x1=y, I have done a few things为了使用 $location.search() 得到 x1=y,我做了一些事情
my list1.js has我的 list1.js 有
var app = angular.module('NGApp', ['ngRoute']); //dependencies : ngRoute
app.config(function ($locationProvider) { //config your locationProvider
$locationProvider.html5Mode(true).hashPrefix('');
});
app.controller('NGCtrl', function ($scope, datasvc, $location) {// inject your location service
//var val = window.location.href.toString().split('=')[1];
var val = $location.search().x1; alert(val);
$scope.xout = function () {
datasvc.out(val)
.then(function (data) {
$scope.x1 = val;
$scope.allMyStuffs = data.all;
});
};
$scope.xout();
});
and my list1.html has我的 list1.html 有
<head>
<base href=".">
</head>
<body ng-controller="NGCtrl">
<div>A<input ng-model="x1"/><br/><textarea ng-model="allMyStuffs"/></div>

My fix is more simple, create a factory, and implement as one variable.我的修复更简单,创建一个工厂,并作为一个变量实现。 For example
例如
angular.module('myApp', []) // This a searchCustom factory. Copy the factory and implement in the controller .factory("searchCustom", function($http,$log){ return { valuesParams : function(params){ paramsResult = []; params = params.replace('(', '').replace(')','').split("&"); for(x in params){ paramsKeyTmp = params[x].split("="); // Si el parametro esta disponible anexamos al vector paramResult if (paramsKeyTmp[1] !== '' && paramsKeyTmp[1] !== ' ' && paramsKeyTmp[1] !== null){ paramsResult.push(params[x]); } } return paramsResult; } } }) .controller("SearchController", function($scope, $http,$routeParams,$log,searchCustom){ $ctrl = this; var valueParams = searchCustom.valuesParams($routeParams.value); valueParams = valueParams.join('&'); $http({ method : "GET", url: webservice+"q?"+valueParams }).then( function successCallback(response){ data = response.data; $scope.cantEncontrados = data.length; $scope.dataSearch = data; } , function errorCallback(response){ console.log(response.statusText); }) })
<html> <head> </head> <body ng-app="myApp"> <div ng-controller="SearchController"> <form action="#" > <input ng-model="param1" placeholder="param1" /> <input ng-model="param2" placeholder="param2"/> <!-- Implement in the html code (param1={{param1}}¶m2={{param2}}) -> this is a one variable, the factory searchCustom split and restructure in the array params --> <a href="#seach/(param1={{param1}}¶m2={{param2}})"> <buttom ng-click="searchData()" >Busqueda</buttom> </a> </form> </div> </body>
Very late answer :( but for someone who is in need, this works Angular js works too :) URLSearchParams Let's have a look at how we can use this new API to get values from the location!很晚的答案:(但是对于有需要的人来说,这对 Angular js 也有效 :) URLSearchParams让我们看看我们如何使用这个新 API 从位置获取值!
// Assuming "?post=1234&action=edit"
// 假设“?post=1234&action=edit”
var urlParams = new URLSearchParams(window.location.search);
console.log(urlParams.has('post')); // true
console.log(urlParams.get('action')); // "edit"
console.log(urlParams.getAll('action')); // ["edit"]
console.log(urlParams.toString()); // "?post=1234&action=edit"
console.log(urlParams.append('active', '1')); // "?
post=1234&action=edit&active=1"
use this function from instead of URLSearchParams使用此函数 from 而不是URLSearchParams
urlParam = function (name) {
var results = new RegExp('[\?&]' + name + '=([^&#]*)')
.exec(window.location.search);
return (results !== null) ? results[1] || 0 : false;
}
console.log(urlParam('action')); //edit
