【问题描述】：
我正在使用此代码的一部分 http://www.jitendrazaa.com/blog/webtech/web/pagination-and-sorting-of-data-table-using-angularjs/ 对 AngularJS 进行分页，但我想使用名为“用户”的 MySQL 数据库表中的数据... 但我面临一个错误，即 valLists 未定义，因此它返回 null 并且什么也不显示....我认为数据类型来自 select.php 导致了这种情况，我不知道如何解决它..任何帮助！
HTML 代码：
<body>
<br />
<br />
<div ng-app="myApp">
<div ng-controller="TableCtrl">
<table class="table">
<thead>
<tr>
<th class="id">User Id
</th>
<th class="name">Name
</th>
<th class="phone">Phone
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="item in ItemsByPage[currentPage]">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.phone}}</td>
</tr>
</tbody>
</table>
<ul class="pagination">
<li><a href="#" ng-click="firstPage()">First</a>
</li>
<li ng-repeat="n in range(ItemsByPage.length)"> <a href="#" ng-click="setPage()" ng-bind="n+1">1</a>
</li>
<li><a href="#" ng-click="lastPage()">Last</a>
</li>
</ul>
</div>
</div>
</body>
JavaScript 代码：
var myApp = angular.module('myApp', []);
myApp.service('ListService', function () {
this.paged = function (valLists, pageSize) {
retVal = [];
for (var i = 0; i < valLists.length; i++) {
if (i % pageSize === 0) {
retVal[Math.floor(i / pageSize)] = [valLists[i]];
} else {
retVal[Math.floor(i / pageSize)].push(valLists[i]);
}
}
return retVal;
};
});
var TableCtrl = myApp.controller('TableCtrl', function ($scope, ListService) {
$scope.pageSize = 2;
$scope.allItems = getData();
$scope.resetAll = function () {
$scope.List = $scope.allItems;
$scope.newId = '';
$scope.newName = '';
$scope.newPhone = '';
$scope.currentPage = 0;
};
function getData1(){
return [{
id : 33,
name : 'hala',
phone: 12345
}]
};
var d = new Array();
function getData() {
$.ajax ({
url: "select.php",
type: 'POST',
//dataType: "json",
data: '',
success: function( data ) {
d = data;
// alert('succ');
},
error: function( ) {
alert('Error select');
}
});
// alert(d);
return d;
}
$scope.pagination = function () {
$scope.ItemsByPage = ListService.paged($scope.List, $scope.pageSize);
};
$scope.setPage = function () {
$scope.currentPage = this.n;
};
$scope.firstPage = function () {
$scope.currentPage = 0;
};
$scope.lastPage = function () {
$scope.currentPage = $scope.ItemsByPage.length - 1;
};
$scope.range = function (input) {
var ret = [];
for (var i = 0; i < input; i++) {
if (i != 0 && i != input - 1) {
ret.push(i);
}
}
return ret;
};
$scope.resetAll();
$scope.pagination();
});
select.php 代码
<?php
header('Content-Type: application/json');
include 'connect.php';
$db = new database();
$db->setDb_name('training');
$db->connect();
$db->select('user',"*");
$data = $db->getResult();
echo json_encode($data);
?>
这里是选择功能：
public function select($table, $rows, $where = null){
$case = 0;
if($this->tableExists($table))
{
$q = ' SELECT ' .$rows.' FROM '.$table;
$query = @mysql_query($q);
$this->numresults = mysql_num_rows($query);
for($i = 0; $i < $this->numresults; $i++)
{
$r = mysql_fetch_array($query);
$key = array_keys($r);
for($x = 0; $x < count($key); $x++)
{
// Sanitizes keys so only alphavalues are allowed
if(!is_int($key[$x]))
{
if(mysql_num_rows($query) > 1)
$this->result[$i][$key[$x]] = $r[$key[$x]];
else if(mysql_num_rows($query) < 1)
$this->result = null;
else
$this->result[$key[$x]] = $r[$key[$x]];
}
// $this->result[$i][$key[$x]] = $r[$key[$x]];
}
}
// print_r ($this->result)."<br/>";
}
else
return false;
}
和getResult()函数：
public function getResult() {
return $this->result;
}
注意1：使用函数 getData1() 而不是 getData() 时效果很好。 注意2：我确信选择功能运行良好并带来如下数据：
[{"id":"3","name":"newname","phone":"321"},
{"id":"4","name":"nnnnnnnnnnn","phone":"66555566"}, {"id":"10","name":"dss","phone":"45321"}, {"id":"11","name":"www","phone":"1234"}, {"id":"15","name":"fghjkl","phone":"34567890"}]
【问题讨论】：
-
这是因为你不知道
asynchronous在ajax中的含义 -
你能解释一下吗，或者告诉我该怎么做？
