我正在进行离子应用。我有一个名为scope.win（）的函数，它应该在测验完成后触发，然后更新JSON文件以将该测验添加到完成的测验数量但它无法正常运行。它不会放弃任何错误。该功能在某个时刻停止运行，应用程序继续运行，没有任何事情发生 这是控制器的文件
angular.module('controllers', ['services'])
.controller('MainCtrl', function ($scope, $state, data) {
$scope.$on('$ionicView.enter', function () {
data.create();
});
$scope.chapter = data.chapterProgress();
})
.controller("BtnClick", function ($scope, lives, data, $cordovaFile, $ionicScrollDelegate) {
var live = 3;
var clickedOn = [];
var numQuestions;
$scope.part2Cred = false;
$scope.part3Cred = false;
$scope.part4Cred = false;
$scope.part5Cred = false;
$scope.part6Cred = false;
$scope.part7Cred = false;
$scope.part8Cred = false;
$scope.part9Cred = false;
$scope.part10Cred = false;
$scope.partQCred = false;
$scope.setNumQuestions = function(num){
numQuestions = num;
}
$scope.updatelives = function (){
//grabs the element that is called liv then updates it
var livesOnPage = document.getElementById('liv');
livesOnPage.innerHTML = live;
}
$scope.wrong = function (event){
var selec = document.getElementById(event.target.id);
if(clickedOn.includes(selec)){}
else{
selec.style.color = "grey";
clickedOn.push(selec);
live = live - 1;
if(live == 0){
$scope.gameover();
}
else{
$scope.updatelives();
}
}
}
$scope.right = function (event,chapter, section){
var selec = document.getElementById(event.target.id);
if(clickedOn.includes(selec)){}
else{
selec.style.color = "green";
clickedOn.push(selec);
numQuestions = numQuestions - 1;
if(numQuestions === 0){
$scope.win(chapter, section);
}
}
}
$scope.gameover = function(){
alert("game over please try again");
live = 3;
$ionicScrollDelegate.scrollTop();
$scope.partQCred = false;
$scope.part1Cred = !$scope.part1Cred;
for(i = 0; i< clickedOn.length;i++){
clickedOn[i].style.color = "rgb(68,68,68)";
}
}
$scope.win = function (chapter, section) {
alert("Well Done");
var data = data.chapterProgress(); // It is at this point that the //function stops running without giving off any error.
alert("Good Job");
var sectionsComplete = data[chapter].sectionsCompleted;
var totalsection = data[chapter].totalSections;
if (section === totalSection) {
window.location.href = "#/chapter1sections";
return;
}
if (section > sectionsComplete) {
data[chapter].sectionsCompleted += 1;
var url = "";
if (ionic.Platform.isAndroid()) {
url = "/android_asset/www/";
}
document.addEventListener('deviceready', function () {
$cordovaFile.writeFile(url + "js/", "chapters.json", data, true)
.then(function (success) {
// success
alert("Json file updated")
window.location.href = "#/chapter1sections";
}, function (error) {
// error
});
});
}
}
});
这是服务文件。它看起来运行正常，但在控制器中有问题的代码部分引用了很多，所以我认为有必要把它放在这里。
angular.module('services', [])
.service('lives', function () {
var live = 3;
return {
getlives: function () {
return live;
},
setlives: function (value) {
live = value;
}
};
})
.service('data', function ($cordovaFile, $http) {
var url = "";
if (ionic.Platform.isAndroid()) {
url = "/android_asset/www/";
}
return {
//Run this function on startup to check if the chapters.json file exists, if not, then it will be created
create: function () {
var init = {
"one": {
"sectionsCompleted": 0,
"totalSections": 4
},
"two": {
"sectionsCompleted": 0,
"totalSections": 1
}
};
$cordovaFile.writeFile(url + "js/", "chapters.json", init, false)
.then(function (success) {
// success
}, function (error) {
// error
});
},
chapterProgress: function () {
return $http.get(url + "js/chapters.json").success(function (response) {
var json = JSON.parse(response);
return json;
}, function (error) {
alert(error);
});
}
}
});
非常感谢您的帮助和时间。
