一切正常,但是当我插入一条记录并尝试编辑同一条记录时,它不会被编辑,并且要编辑同一条记录,我必须刷新页面,更新中也会发生同样的情况,一旦更新记录,我必须刷新编辑同一条记录的页面

<html ng-app="crudApp">
<head>
<meta charset="UTF-8">
<title>Angular js</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
</head>

<body ng-controller="DbController">
<form id="form" name="employee">
First Name: <input type="text" ng-model="firstname"><br/><br/>
Last Name: <input type="text" ng-model="lastname"><br/><br/>
<input type="submit" name="btnInsert" id="Insert" value="Insert" ng-click='insertData()'/>
<input type="submit" name="btnUpdate" id="Update"value="Update" ng-click='UpdateData(currentUser)'/>
</form>

<div>
<table border="1">
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Delete</th>
<th>Edit</th>
</tr>
<tr ng-repeat="detail in details">
<td>{{detail.firstname}}</td>
<td>{{detail.lastname}}</td>
<td><input type="button" value="Delete" ng-click="deleteInfo(detail.id)"/></td>
<td><input type="button" value="Edit" ng-click="editInfo(detail.id)"/></td>
</tr>
</table>
</div>
<script>
var crudApp = angular.module('crudApp', []);
crudApp.controller("DbController", ['$scope', '$http', function ($scope, $http) {

getInfo();
function getInfo() {
$http.post('select.php').success(function (data) {
// Stored the returned data into scope
$scope.details = data;
});
}

$scope.deleteInfo = function (info) {
$http.post('delete.php', {del_id: info
}).success(function (result) {
getInfo()
console.log(result);
});
}

$scope.insertData = function () {
$http.post("insert.php", {
'firstname': $scope.firstname,
'lastname': $scope.lastname,
}).success(function () {
getInfo();
document.getElementById("form").reset();
});
}


$scope.editInfo = function (info) {
$scope.currentUser = info;
$http.post('edit.php', {edit_id: $scope.currentUser,
}).success(function (result) {
$scope.firstname = result[0]['firstname'],
$scope.lastname = result[0]['lastname'],
$("#Insert").hide();
$("#Update").show();
});
}

$scope.UpdateData = function (currentUser) {
$http.post("update.php", {
'firstname': $scope.firstname,
'lastname': $scope.lastname,
'update_id': currentUser,
}).success(function (result) {
getInfo();
$("#Insert").show();
$("#Update").hide();
document.getElementById("form").reset();
});
}

}]);

</script>

</body>

</html>

最佳答案

编辑后,您将把响应数据插入到新变量中。这不应该发生。您应该仅更新旧数据(即 $scope.detail )。

方法如下:

首先,在您的<table>中代码,您必须再传递 1 个参数,即 $index 。这个$index是我们必须更新的记录的键。我们需要它来更新 $scope.detail 中的记录.

<table border="1">
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Delete</th>
<th>Edit</th>
</tr>
<tr ng-repeat="detail in details">
<td>{{detail.firstname}}</td>
<td>{{detail.lastname}}</td>
<td><input type="button" value="Delete" ng-click="deleteInfo(detail.id)"/></td>
<td><input type="button" value="Edit" ng-click="editInfo(detail.id, $index)"/></td>
</tr>
</table>

其次,请参阅 editInfo() 的代码。而不是将响应数据分配给新变量。我们正在更新 $scope.detail 的旧数据仅有的。了解我们如何使用 index 找到我们的数据我们从上一步中获得的变量。

//info: this info is the detail.id that you've passed from the table
//index: this is the index of the record from $scope.detail that we want want to edit.
$scope.editInfo = function (info, index) {
$scope.currentUser = info;
$http.post('edit.php', {edit_id: $scope.currentUser,
}).success(function (result) {

$scope.detail[index] = result[0]['firstname'];
$scope.detail[index] = result[0]['lastname'];

$("#Insert").hide();
$("#Update").show();
});
}
