我从php url获取数组格式的ajax响应.如何在jQuery中提取数组响应值？供参考:

PHP数组是:

$response = array('msg' => 'Hello', 'html' => '<b>Good bye</b>');

我在我的ajax响应中得到了$ response数组.即

var promo = "promo=45fdf4684sfd";
$.ajax({
    type: "POST",
    url: baseJsUrl + "/users/calc_discount",
    data: promo,
    success: function (msg) { // I am getting $response here as ajax response.
        //alert(msg);

        // Here I want to check whether response is in array format or not. if it is in array format, I want to extract msg here and want to use response array values.
    }
});

让我知道答案.谢谢.

我正在使用CakePHP进行开发,这是我的页面控制器:

<?php
class PagesController extends AppController
{
    var $name = 'Pages';
    var $helpers = array('Html', 'Session');
    var $uses = array();

    function display()
    {
        $path = func_get_args();

        $count = count($path);
        if (!$count) {
            $this->redirect('/');
        }
        $page = $subpage = $title_for_layout = null;

        if (!empty($path[0])) {
            $page = $path[0];
        }
        if (!empty($path[1])) {
            $subpage = $path[1];
        }
        if (!empty($path[$count - 1])) {
            $title_for_layout = Inflector::humanize($path[$count - 1]);
        }
        $this->set(compact('page', 'subpage', 'title_for_layout'));
        $this->render(implode('/', $path));

        $this->loadModel('Curso', 2);

        $select = $this->Curso->query("SELECT * FROM cursos ORDER …

当我在php中没有计算行数时,我确实喜欢这样

   $sql=mysql_query("select * from users where username='$email'") or die("select error".mysql_query());

   $no_rows=mysql_num_rows($sql);

但我不知道如何在蛋糕php中做到这一点,我的数据来自于此

[User] => Array
    (
        [first_name] => arjun
        [last_name] => tyagi
        [username] => arjun@gmail.com
        [phone_no] => 9569908024
        [mobile_no] => 9569908024
        [state_id] => 2
        [location_id] => 15
        [password] => cffa41a028807034b54b5849d5f4d3ca7532e701
        [confirm_password] => 12345
    )

我的员工表结构如下图所示

以下查询获得部门ID基于部门平均最高薪水

SELECT dep_id
FROM employee
GROUP BY dep_id
ORDER BY AVG( salary ) DESC
LIMIT 1 

产量

dep_id
2

但我在更新查询中有问题

UPDATE employee
SET salary = salary +1000
where dep_id = (
SELECT dep_id
   FROM employee
   GROUP BY dep_id
   ORDER BY AVG( salary ) DESC
   LIMIT 1
)

$('#button').live('click', function () {
    values_array = [];
    $('.field').each(function () {
        values_array.push = $(this).val();
    });
    $.ajax({
        url: 'page.php',
        data: {
            array_a: values_array
        },
        type: 'POST',

        success: function (data) {
            $('#div').html(data);
        }
    });
});


//page.php
echo $_POST['array_a'] . "<br/>"; //The line break echos, but nothing else

答:我是否需要迭代每个类$.each以创建一个正确的数组,和

B.)为什么不回复它？

我想更改宽度为41%宽度为的所有子div(parent div id = product_list)31%.

在jquery中是否有任何方法可以找到宽度为41%(仅在父div id = product_list下)的子div并将宽度更改为31%

注意:我无法设置代码子div id bocz那些随机更改的时间.

这是HTML代码

<div id="product_list" style="float:none;">
  <div id="row_4fec46be9210e" style="margin-right: 5px; width:31%; float:left;">
      <div id="row_4fec" style="margin-right: 5px; width:15%; float:left;"></div>
      <div id="row_4fec" style="margin-right: 5px; width:16%; float:left;"></div>
  <div>
  <div id="row_4fec46be92339" style="margin-right: 5px; width:31%; float:left;"></div>
  <div id="row_4fec46be92523" style="margin-right: 5px; width:31%; float:left;"></div>
  <div id="row_4fec46be92523" style="margin-right: 5px; width:41%; float:left;"></div>
  <div id="row_4fec46be92523" style="margin-right: 5px; width:41%; float:left;"></div>
 </div>
