我正在使用带有cordova的angularJs。
我有一个ng-repeat,每个项目都有一个ng-click,它将每个项目的值放在一个数组中。此外,当我点击时,它正在删除并向div添加一个新类(使用ng-repeat的$ index)。像清单一样。
事实是,当我重新加载ng-repeat时,我丢失了我刚刚点击它时添加的类。 当我调用重新加载ng-repeat所示项目的函数时,我尝试(使用未更改的数组)重新添加类。但它没有添加类:/
以下是我的代码:
<div id="ami" class="list-group">
<div href="#" class="list-group-item" ng-repeat="ami in listeAmis"> {{ami.pseudo}}<i id="checkAmi{{$index}}" class="fa fa-circle-o pull-right" ng-click="mapCtrl.checkAmi(ami.pseudo, $index);"></i><i class="fa fa-user pull-left" ></i></div>
</div>
的Javascript
var amisNotifies = [];
mapCtrl.checkAmi = checkAmi;
function checkAmi(pseudo, id) {
var info = ({
pseudo: pseudo,
id: id
});
var getIndexOf = function (psdu) {
for (var i = 0; i < amisNotifies.length; i++) {
if (amisNotifies[i].pseudo === psdu) {
return i;
}
}
return -1;
};
if (amisNotifies.length > 0) {
var index = getIndexOf(pseudo);
if (index > -1) {
//so already exists. now remove it.
Array.prototype.splice.call(amisNotifies, index, 1);
$("#checkAmi" + id).addClass("fa-circle-o");
$("#checkAmi" + id).removeClass("fa-check-circle-o");
}
else {
//does not exist, now add it
amisNotifies.push(info);
$("#checkAmi" + id).removeClass("fa-circle-o");
$("#checkAmi" + id).addClass("fa-check-circle-o");
}
} else {
amisNotifies.push(info);
$("#checkAmi" + id).removeClass("fa-circle-o");
$("#checkAmi" + id).addClass("fa-check-circle-o");
}
console.log(amisNotifies);
}
所以,当我重新加载ng-repeat显示的数据时,我试图把它放进去,但它不会再改变这个类...
if (amisNotifies.length > 0) {
for (var i = 0; i < amisNotifies.length; i++) {
console.log(amisNotifies[i].id);
$("#checkAmi" + amisNotifies[i].id).removeClass("fa-circle-o");
$("#checkAmi" + amisNotifies[i].id).addClass("fa-check-circle-o");
}
}

HTML中包含动态ng-class的数组,其数量取决于索引:
<div id="ami" class="list-group">
<div href="#" class="list-group-item" ng-repeat="ami in listeAmis"> {{ami.pseudo}}
<i id="checkAmi{{$index}}" ng-class="isChecked[{{$index}}]" ng-click="mapCtrl.checkAmi(ami.pseudo, $index);"></i>
</div>
</div>
根据ng-repeat的大小声明变量数:
if ($scope.listeAmis.length > 0) {
for (var j = 0; j < $scope.listeAmis.length; j++) {
$scope.isChecked[j] = "fa fa-circle-o pull-right";
}
}
检查您刚刚点击的行并更改ng-class(此外,我存储了刚刚单击的行的索引,以便在我点击它时以不同方式声明$ scope.isChecked [j] ...
mapCtrl.checkAmi = checkAmi;
function checkAmi(pseudo, id) {
var info = ({
pseudo: pseudo,
id: id
});
var getIndexOf = function (psdu) {
for (var i = 0; i < amisNotifies.length; i++) {
if (amisNotifies[i].pseudo === psdu) {
return i;
}
}
return -1;
};
if (amisNotifies.length > 0) {
var index = getIndexOf(pseudo);
if (index > -1) {
//so already exists. now remove it.
Array.prototype.splice.call(amisNotifies, index, 1);
$scope.isChecked[id] = "fa fa-circle-o pull-right";
} else {
//does not exist, now add it
amisNotifies.push(info);
$scope.isChecked[id] = "fa fa-check-circle-o pull-right";
}
} else {
amisNotifies.push(info);
$scope.isChecked[id] = "fa fa-check-circle-o pull-right";
}
console.log(amisNotifies);
}
