我是 AngularJS 的新手，目前我正在嘗試創建一個用于跟蹤費用的水療中心作為一個簡單的專案，但我的代碼存在一些問題。
我設法完成了大部分功能，但我卡在了編輯按鈕和編輯功能上。我正在嘗試制作行內編輯功能，因為我已經有一個表單輸入。
這是html和js代碼：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Expenses Tracker</title>
<link rel="stylesheet" href="bootstrap.min.css">
<link href="style.css" rel="stylesheet">
</head>
<body>
<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
<div class="container">
<div class="navbar-header">
<span class="navbar-brand"><img src="logo.png" class="brand" height="40" />
Simple Expenses App Tracker</span>
</div>
</div>
</nav>
<div class="main" ng-app="myList" ng-controller="myListController">
<img src="logo.png" class="logo">
<form ng-submit="newItem()" class="form">
<input required type="number" placeholder="Amount" ng-model="amount">
<input required type="text" placeholder="Description" ng-model="description">
<input type="submit" value="Submit" class="btn btn-success">
</form>
<ul>
<li ng-repeat="item in items">
<span class="pull-left"> {{item.amount}} den.</span> {{item.description}}
<span class="buttons">
<input type="button" value="Edit" class="btn btn-primary" >
<input type="button" ng-click="deleteItem($index)" value="Delete" class="btn btn-danger">
</span>
</li>
<br>
<li><span class="total">{{totalPrice()}} den.</span> <span class="expense"> Total Expenses</span></li>
</ul>
</div>
<script src="bootstrap.min.js"></script>
<script src="angular.min.js"></script>
<script src="angular-route.min.js"></script>
<script src="app.js"></script>
</body>
</html>
var myApp = angular.module("myList", []);
myApp.controller("myListController", function($scope) {
$scope.items = [];
$scope.newItem = function() {
$scope.items.push({description:$scope.description, amount: $scope.amount});
$scope.description = '';
$scope.amount = 0
};
$scope.deleteItem = function(index) {
$scope.items.splice(index, 1);
}
$scope.totalPrice = function() {
var total = 0;
for(count=0; count<$scope.items.length;count ){
total = $scope.items[count].amount;
}
return total;
};
});
uj5u.com熱心網友回復：
您可以嘗試以下方法：
$scope.editItem = function(index) {
$scope.amount = $scope.items[index].amount;
$scope.description = $scope.items[index].description;
$scope.deleteItem(index);
}
我還建議您閱讀這本書： https ://www.newline.co/ng-book/modern-ng1/
盡量不要使用 $scope 進行系結和用戶組件。除非你真的不在乎這個專案的去向。
