单例模式:只允许实例化一次的对象类
这种在基本的编程中可能已经经常的用到,只是不知道是单例模式,就是将方法和属性封装到一个对象里。
比如config.js文件,service.js里都会经常用到:
app.factory(‘payInfo‘, function($location) {
// Might use a resource here that returns a JSON array
return {
getStatusMsg:function(Paystatus){
switch(Paystatus){
case 0:
return "支付成功!";
case 1:
return "支付失败!";
case 2:
return "取消支付!";
}
},
getPayType:function(type){
switch(type){
case ‘ticket‘:
return 0;
case ‘red‘:
return 1;
case ‘recharge‘:
return 2;
}
},
getHasPasswordFlag:function(){
return 1;
},
getHasRedFlag:function(){
return 1;
},
getPayPathType:function(type){
switch(type){
case ‘account‘:
return ‘/paymentAccount.html‘;
case ‘red‘:
return ‘/paymentRed.html‘;
}
},
getAccountTypeId:function(type){
switch(type){
case ‘UnionPay‘:
return 3;
case ‘Account‘:
return 1;
case ‘LianLian‘:
return 6;
}
},
clearSuccessLocalStrorage:function(){
localStorage.removeItem(‘paySuccessContent‘);
localStorage.removeItem(‘paySuccessContentSecond‘);
},
getPaySuccessUrl:function(){
return ‘×××?‘+$location.url().split(‘?‘)[1];
}
}
})
.factory(‘Request‘,function($http){
return{
sendRequest:function(form_data,successCallBack,exCallBack){
console.log(form_data);
var req = {
method: ‘POST‘,
url: ‘××ב,
data: form_data
}
$http(req).then(function(response_data){
successCallBack(response_data);
}, function(response_ex){
exCallBack(response_ex);
});
}
}
})
.factory(‘DECODE‘,function(){
return{
base:function(decodeurl){
for(var key in decodeurl){
decodeurl[key] = window.atob(decodeurl[key]);
}
}
}
})
