小编gau*_*kum的帖子

我写了这样的代码. <img id='test_img' src='../../..' />

我想在图像加载上获得此图像的ID,如,

$(img).load(function() {
// Here I want to get image id i.e. test_img
});

你能帮我么？

谢谢.

我有一个用户模型.在其中,我设置了注册用户时使用的验证.这很好.但是当用户编辑他的个人资料信息时,我不想验证一些字段,如密码,电子邮件等.怎么可能.下面是代码.

<?php
class User extends AppModel{

    var $name = 'User';

    // used when user registers
    var $validate = array(

        'login' => array(
            'minLength' => array(
                'rule' => array('minLength', '6'),
                'field' => 'login', 
                'message' => 'mimimum 6 characters long'
                )
        ),
        'password' => array( // don't want to validate in edit profile page
            'minLength' => array(
                'rule' => array('minLength', '6'),
                'field' => 'password',
                'message' => 'minimum 6 characters long'
                )
        ),
        'email' => array(
            array(
            'rule' => 'email',
            'message' => 'please …

我有遵循UL - LI html.

<UL>
<LI><span id='select1'>Text</span></LI>
<LI><span id='select2'>Text</span></LI>
<LI><span id='select3'>Text</span></LI>
<LI><span id='select4'>Text</span></LI>
<LI><span id='select5'>Text</span></LI>
<LI><span id='select6'>Text</span></LI>
</UL>

如果我点击特定的<span>,它的背景颜色应该改变.即如果我点击跨度id='select3',它的背景颜色应该改变.

如何使用jQuery完成此操作？

有谁知道如何从型号名称获取表名？此外,我想获取该模型/表名称的所有列名称及其类型.是否有可能获得给定型号名称的详细信息？

谢谢.

我收到此错误:#1054 - 'on子句'中的未知列't.mobile'

SELECT t.*,v.name,v.contact_person_email,l.firstname as memname 
FROM transactions t , vendor v
LEFT JOIN loyalty_members l ON (t.mobile=l.mobile) 
WHERE t.vendor_id ='N1WU95' 
AND v.alert_mail = '2'
AND t.add_date  <= '2011-07-22 09:00:00'
AND t.add_date >= '2011-07-21 09:00:00'
AND t.vendor_id = v.id
AND t.type = '1' 
AND t.deleted != '1'
AND t.reference_id = '0'
GROUP BY t.mobile 
HAVING COUNT(t.mobile) > 1;

任何人都可以帮我解决这个问题吗？

谢谢.

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.

我有两个名为message.php和的模型user.php

在message.php中,我有以下方法计算已验证用户的消息的#no.

<?php
class Message extends AppModel {
   ...
   ...
   ...
   function getInboxCount($userId) {
      // Here I want to get list of ids of verified users. It means I need to use User model for this. How is it possible?
      // $ids = $this->User->find('list', array('conditions' => array('User.status' => 'verified'))); Will this work?
   }
}
?>

那么如何在Message模型中使用User模型呢？

我正在使用CakePHP 2.1

我在数据库中有以下字段.

id
views
max_views

我想获取views < max_views使用查询查询的记录.那么查询应该是什么呢？

谢谢.
