[英]How to get the Local Storage data into the view file Using Angular js
你好，我是平均堆栈的初学者。 我在localstorage中有数据，我想从本地存储中获取数据并在html文件中显示，但我不知道如何获取它。 在视图文件上。
$scope.useredit = function (d) {
var user_id = d._id;
var dataToModify;
angular.forEach($scope.dp, function (value, key) {
if (user_id == value._id) {
dataToModify = value;
$localStorage.userData = dataToModify;
console.log($localStorage.userData.name);
$location.path('/useredit');
}
});
}
当我输入localStorage时; 进入控制台它显示
ngStorage-userData
:
"{
"_id":"5846692617e0575c0e0c2211",
"password":123456,
"email":"montyy1981@gmail.com",
"name":"digvijay12","__v":0
}"
如何将它的值放入视图文件中。我用过
<div>{{userData.email}}</div>
但它没有显示data.please帮助我如何获取localstorage数据并显示到视图文件中。
您可以在没有ngStorage的情况下使用核心概念.... https://developer.mozilla.org/en-US/docs/Web/API/Storage/LocalStorage
localStorage.setItem("userData", $scope.Data);
$scope.storageData = localStorage.getItem("userData");
<p>{{storageData.email}}</p>
如何在任何地方获取localStoragedata这很简单我们必须将localStorage数据传递给控制器全局变量假设
我们将数据存入localstorage
$scope.useredit = function (d) {
var user_id = d._id;
var dataToModify;
angular.forEach($scope.dp, function (value, key) {
if (user_id == value._id) {
dataToModify = value;
$localStorage.userData = dataToModify;
console.log($localStorage.userData.name);
$location.path('/useredit');
}
});
}
我们必须在控制器启动后将pass $localStorage.userData定义到另一个变量中。
app.controller("usercontroller",function($scope,$http, $localStorage,$location){
$scope.registeruser = $localStorage.userData;
$scope.useredit = function (d) {
var user_id = d._id;
var dataToModify;
angular.forEach($scope.dp, function (value, key) {
if (user_id == value._id) {
dataToModify = value;
$localStorage.userData = dataToModify;
console.log($localStorage.userData.name);
$location.path('/useredit');
}
});
}
});
为了更好地理解，请单击此演示
在控制器中，您需要注入“ngStorage” angular.module('MyApp', ["ngStorage"]) 。 并添加依赖脚本链接<script src="https://cdn.jsdelivr.net/ngstorage/0.3.6/ngStorage.min.js"></script>
HTML
<html ng-app="MyApp">
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.1/angular.min.js"></script>
<script src="https://cdn.jsdelivr.net/ngstorage/0.3.6/ngStorage.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<div ng-controller="MyController">
<input type="button" value = "Save" ng-click = "Save()" />
<input type="button" value = "Get" ng-click = "Get()" />
</div>
</body>
</html>
的script.js
var app = angular.module('MyApp', ["ngStorage"])
app.controller('MyController', function ($scope, $localStorage, $sessionStorage, $window) {
$scope.Save = function () {
$localStorage.email = "xyz@gmail.com";
}
$scope.Get = function () {
$window.alert($localStorage.email);
}
});
