我正在尝试使用 localStorage 制作一个简单的插入、删除、更新表单来存储我的数据。当我单击添加按钮时,它显示错误
TypeError: $scope.lstLaptop.push 不是一个函数。
如果我错了,我回到我的代码并检查语法,但我认为我的代码只有 3 行,看起来很平常。你能告诉我我遗漏了什么或者问题出在哪里吗?
只是忽略了我的其他代码并请检查我的控制器 lapCreateUpdateCtrl,我不知道我错了什么。
HTML 文件:
<div class="container">
<table class="table table-hover">
<tr>
<th>Laptop Model</th>
<th>Price($)</th>
<th>Option</th>
</tr>
<tr ng-repeat = "laptops in lstLaptop track by $index">
<td><p ng-bind = laptops.model></p></td>
<td><p ng-bind = laptops.price></p></td>
<td><button type="button" ng-click="remove1($index)"
class="btn btn-danger btn-xs">
Delete
</button>
<button type="button" ng-click="edit1($index)"
class="btn btn-warning btn-xs">
Edit
</button>
<button type="button" ng-click="update1($index)"
class="btn btn-info btn-xs">
Update
</button>
</td>
</tr>
</table>
<button type="button" class="btn btn-success btn-sm"
ng-click="save()">
Save
</button>
</div>
</div>
</body>
app.JS 文件:
routerApp.controller('lapCreateUpdateCtrl', ["$scope", function($scope){
$scope.laptop = {};
$scope.lstLaptop = [];
function init(){
var strLaptop = window.localStorage.getItem("LAPTOP_KEY");
if(strLaptop){
$scope.lstLaptop = JSON.parse(strLaptop);
}
}
init();
$scope.add1 = function(){
$scope.lstLaptop.push($scope.laptop);
$scope.laptop = {};
}
$scope.remove1 = function(index){
$scope.lstLaptop.splice(index,1);
alert("Deleted!");
}
$scope.edit1 = function(index){
$scope.laptop = angular.copy($scope.lstLaptop[index]);
}
$scope.update1 = function(index){
$scope.lstLaptop.splice(index, 1, $scope.laptop);
$scope.laptop = {};
}
$scope.save=function(){
window.localStorage.setItem("LAPTOP_KEY", JSON.stringify($scope.lstLaptop));
}
}]);
我想从文本框中输入内容
<input type="text" ng-model="laptop.model" id="model" name="model"
placeholder="Model" required />
<input type="number" ng-model="laptop.price" id="price" name="price"
placeholder="Price" required />
<button type="button" ng-click="add()">
Add Desktop
</button>
