比较和插入Angular JSon数据
[英]Comparing and inserting Angular JSon Data
问题描述
我无法弄清楚为什么我拥有的比较功能和我拥有的插入功能不起作用。 我相信其中一部分可能是因为按钮从未调用过该函数吗？ 我怎么能说出来呢？ 似乎警报未在角度代码中起作用。
这是我的loginHandler.js
(function() {
var app = angular.module('loginHandler', []);
app.controller('LoginController', ['$http' ,function($http){
var database = this;
this.validated = false;
database.dbData = [];
$http.get('/resources/DatabaseObject.json').success(function(data){
database.dbData = data;
});
this.login = function(credentials){
loggedInUser = credentals.username;
validated = true;
$http.get('/resources/DatabaseObject.json').success(function(data){
$scope.dbData.push({"123":{"username":"meph","ip":"123","timeLastLogin":"123"}}, "session");
});
};
this.checkSession = function(){
var ip = "123456";
if(session.ip.equals(123456)){
return true;
}
};
}]);
})();
这两个功能均不起作用。...登录或checkSession不起作用。
DatabaseObject.json
[{
"users": {
"cra": {
"firstName": "Jn",
"lastName": "it",
"username": "dmph",
"email": "ran61@yahoo.com",
"ip": "192.168.1.1",
"password": "1234",
"computerName": "os",
"prviateKey": "1D3RW12390ASLEWRQ1235"
},
"mus": {
"firstName": "James",
"lastName": "mh",
"username": "ch",
"email": "j61@gmail.com",
"ip": "192.168.1.1",
"password": "11212",
"computerName": "ops",
"prviateKey": "1D3RW12390ASLEWRQ1235"
}
},
"session": {
"123456": {
"username": "crh",
"ip": "123456",
"timeLastLogin": "123456787654"
}
}
}]
这是我的html

我不确定该提交按钮是否正确...。B！ 抱歉...。我真的很讨厌这个东西！ 我希望有人能帮助我更好地理解它，我一直在尝试各种不同的方法而无济于事。

该push不起作用，因为您具有database.dbData ，但是尝试推送到$scope.dbData （不存在）中。
比较不起作用，因为您将其与session.ip （未在任何地方定义）进行比较。

我相信是因为您正在使用this. 而不是$scope.
另外，您没有将$scope传递给参数...
app.controller('LoginController', ['$http' ,function($http){
它应该是：
app.controller('LoginController', ['$http, $scope' ,function($http, $scope){
在下面，您应该使用：（不是this ）
$scope.login = function () { /* ... */ };
$scope.checkSession = function () { /* ... */ };
将JSON数据插入表
