Ajax响应方式错误

Sto*_*per 6 php ajax jquery post zend-framework

任务:当我从select tag customer(我有customer_id)中选择时,它必须得到DB的请求并返回所有客户字段.然后它必须自动填充一些输入.我尝试制作ajax + jQuery.Ajax很好.它现在正在工作!

这是JS:

我弄明白了:

<script>
$(document).ready(function() {
    $('#customer_load').change(function() {
        $.ajax({
            url: '<?= $this->url(array('action' => 'ajax', 'controller' => 'baza')) ?>',
            type: 'POST',
            dataType: 'json',
            data: {
                    // list of request parameters 
                    'customer_id':  $(this).attr('value')
            },
            success: function(data) {
                    //alert(data.current_discount);
                    $('#extra_discount').val(data.extra_discount);
                    $('#current_discount').val(data.current_discount);
                    $('#customer_number').val(data.customer_id);
            }
        });
    });
});

从您的帖子中很难理解问题是在客户端还是服务器端......在您的第一个示例中,您没有customer_id在ajax请求中使用,并且不需要将值转换为Numberjavascript。

使用下面的 AJAX 请求:

$(document).ready(function(){
   $.ajax({
     url: <?= $this->url(array('action' => 'add', 'controller' => 'baza')) ?>,
     type: 'POST',
     dataType: 'json',
     data: {
        // list of request parameters 
        'customer_id': $('select[name=customer_id] option:selected').val(),
     },
     success: function(results){
         // analyze your response and add custom logic
         console.debug(result);
     }
   });
});

根据您的 PHP 代码,您使事情变得过于复杂。在操作顶部添加检查,并在尝试使其工作时将其注释掉(这样您可以baza/add直接在浏览器中进行测试),一旦工作正常,请取消注释并进行测试。使用JSON 视图助手输出 json。

   public function addAction() 
   {
        // checks/validation/etc

        // do some processing...               
        $result = $this->_customers->fetchSelected($id);

        // Send the JSON response:
        $this->_helper->json($result);
   }
