AngularJS SQL
在前面章節(jié)中的代碼也可以用于讀取數(shù)據(jù)庫(kù)中的數(shù)據(jù)。
使用 PHP 從 MySQL 中獲取數(shù)據(jù)
AngularJS 實(shí)例
<div ng-app="" ng-controller="customersController">
<table>
<tr ng-repeat="x in names">
<td>{{ x.Name }}</td>
<td>{{ x.Country }}</td>
</tr>
</table>
</div>
<script>
function customersController($scope,$http) {
var site = "http://www.w3cschool.cn";
var page = "/try/angularjs/data/Customers_MySQL.php";
$http.get(site + page)
.success(function(response) {$scope.names = response;});
}
</script>
ASP.NET 中執(zhí)行 SQL 獲取數(shù)據(jù)
AngularJS 實(shí)例
<div ng-app="" ng-controller="customersController">
<table>
<tr ng-repeat="x in names">
<td>{{ x.Name }}</td>
<td>{{ x.Country }}</td>
</tr>
</table>
</div>
<script>
function customersController($scope,$http) {
var site = "http://www.w3cschool.cn";
var page = "/try/angularjs/data/Customers_SQL.aspx";
$http.get(site + page)
.success(function(response) {$scope.names = response;});
}
</script>
PHP 讀取 MySQL 數(shù)據(jù)代碼
<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type: text/html; charset=UTF-8");
$conn = new mysqli("myServer", "myUser", "myPassword", "Northwind");
$result = $conn->query("SELECT CompanyName, City, Country FROM Customers");
$outp "[";
while($rs = $result->fetch_array(MYSQLI_ASSOC)) {
if ($outp != "[") {$outp .= ",";}
$outp .= '{"Name":"' . $rs["CompanyName"] . '",';
$outp .= '"City":"' . $rs["City"] . '",';
$outp .= '"Country":"'. $rs["Country"] . '"}';
}
$outp .="]";
$conn->close();
echo($outp);
?>
PHP 讀取 MS Access 代碼
<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type: text/html; charset=ISO-8859-1");
$conn = new COM("ADODB.Connection");
$conn->open("PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=Northwind.mdb");
$rs = $conn->execute("SELECT CompanyName, City, Country FROM Customers");
$outp = "[";
while (!$rs->EOF) {
if ($outp != "[") {$outp .= ",";}
$outp .= '{"Name":"' . $rs["CompanyName"] . '",';
$outp .= '"City":"' . $rs["City"] . '",';
$outp .= '"Country":"'. $rs["Country"] . '"}';
$rs->MoveNext();
}
$outp .= "]";
$conn->close();
echo ($outp);
