Question

很好地通过ng-click传递一个php变量但是我怎么能通过ng-click函数传递完整的php对象我已成功通过JavaScript对象但我无法通过php对象任何帮助将不胜感激。这是我的剧本：

<ul>
   <!-- Retrieving of main products -->
                            <? 
                              if(isset($products)):
                                foreach($products as $row):  

                            ?>
                                <li>
                                    <a href="products/<?=$row->sub_c_id?>/<?=$row->pid?>" class="title colr"><?=$row->pname?></a>
                                    <a href="products/<?=$row->sub_c_id?>/<?=$row->pid?>" class="thumb">
                                     <img src="<?php echo base_url(); ?>uploads/<?=$row->product_pic?>" style="width:157px; height:181px;" alt="" />
                                    </a>

                                    <div class="prodbuttons">
                                        <p class="price bold"><?=$row->pprice?></p>
                                        <a class="cart upper" ng-click="addtocart(<?=$row->pid?>,'<?=$this->session->userdata('session_id'); ?>','<?=$row->pname?>',<?=$row->pprice?>,<?=$row->pquantity?>,<?=$row->sub_c_id?>,'<?=$row->product_pic?>','<?=$row->color?>','<?=$row->size?>',1)">Add to Cart</a>
                                        <a ng-click="check(<? json_encode($row) ?>)">email me</a>
                                    </div>
                                </li>
                             <? endforeach; endif; ?>  


                            </ul>

我也尝试过这样但它也给了我错误：

<a ng-click="check(<? echo json_encode($row) ?>)">email me</a>

Angular js脚本：

$scope.addtocart=function(pid,current_session_id,pname,pprice,pquantity,sub_c_id,product_pic,color,size,qty){
             $scope.errors.splice(0, $scope.errors.length); // remove all error messages
             $scope.msgs.splice(0, $scope.msgs.length);
             $http.post('/product/ng_insertincart', { pid : pid, current_session_id : current_session_id, pname : pname, pprice : pprice, pquantity : pquantity,sub_c_id : sub_c_id,product_pic : product_pic,color : color,size : size, qty : qty}
                        ).success(function(data, status, headers, config) {
                            if (data.msg != '')
                            {
                                $scope.msgs.push(data.msg);
                                console.log(data);
                            }
                            else
                            {
                                $scope.msgs.push(data.msg);
                            }
                        }).error(function(data, status) { // called asynchronously if an error occurs
                           // or server returns response with an error status.
                            $scope.errors.push(status);
                        });
        }
     $scope.check=function(argument) {
         console.log(argument);
     }

让人惊讶。既然你的客户端以某种方式迫使你这样做，那么至少将php内容移动到你的角度控制器。类似的东西：

var controller = function()
{
<?php 
    // Convert product objects to array then encode as json
    $items = array();
    foreach($products as $product) {
        $item = array(
            'pid' => $product->pid,
            'pprice' => $product->pprice,
            ...
        $items[] = $item;
     }
     $productsJson = json_encode($items);
?>
$scope.products = angular.fromJson('<?php echo $productsJson; ?>');

现在您的控制器中有一个合适的产品阵列，您可以在模板中使用良好的重复数据。但即使将$ products转换为json字符串也不需要在模板中完成。在你的主要PHP代码中执行它然后只是将字符串传递给模板。还有一些序列化程序可以帮助将php对象转换为数组：http://symfony.com/doc/current/components/serializer.html

您可能需要将对象输出为正在执行的json，但要确保将其作为字符串传递给作用域函数，方法是在其周围放置单引号：

<a ng-click="check('<? echo json_encode($row) ?>')">email me</a>

然后在你的函数中：

$scope.check = function(obj) {
obj = angular.fromJson(obj);
// do something
}
