Json返回[object object]而不是array [英] Json Returning [object object] instead of array

问题描述

我将json数据输入Sencha touch应用程序。这是json：

I have json data being fed into a Sencha touch app. Here's the json:

http://pastie.org/2622260 - （当然是为一个例子而修改）

http://pastie.org/2622260 - (modified for an example, of course)

当我返回images和console.log时，它会返回以下内容：

When I return the "images" and console.log it, it returns the following:

images: "[object Object],[object Object],[object Object],[object Object],[object Object]"

而不是网址。

我的json编码器看起来像这样（我将数据从Wordpress网站中拉出来）：

My json encoder looks like this (I'm pulling the data out of a Wordpress site):

 case 'posts':
    foreach(get_posts('numberposts=50&category=') as $post) {

            $count = 0;
            $imgurl = array();
            foreach( get_group('Photo', $post->ID) as $images){
                $count++;
                $imgurl[] = array(
                    'count'=>$count,
                    'imageurl'=>get('photo_image_file', $count, 1, false, $post->ID),
                );
            }

      $json['posts'][] = array(
        'id'=>$post->ID,
        'title'=>$post->post_title,
        'body'=>apply_filters('the_excerpt', $post->post_content),
        'date'=>$post->post_date,
        'user'=>get_userdata($post->post_author)->user_firstname,            
    'images'=>$imgurl
      );

    }
}

    header('Content-type: application/json');

    echo json_encode($json);
    exit();

我正在寻找的是返回图片网址数组，而不是[我目前得到的对象对象。

What I am looking for it to do is to return the array of image urls, rather than the [object object] that I am currently getting.

编辑：这是我用来尝试拉出图像的sencha代码：

Here is the sencha code I'm using to try to pull the imageurl out:

    console.log(this.record.data);

    console.log(this.record.data.images);
    console.log(this.record.data.images.length);

    var numberOfPages = this.record.data.images.length;
    // Create pages for the carousel
    var pages = [];
    for (var i=0; i<numberOfPages; i++) {
        pages.push(new Ext.Component({
            id: 'page'+i,
            cls: 'page',
            tpl: '<tpl for=".">{imageurl}</tpl>',
            //html:'test',
        }));
    }

    // Create the carousel
    this.carousel = new Ext.Carousel({
        id: 'carousel',
        title:'Gallery',
        iconCls:'photos2',
        defaults: {
            cls: 'card'
        },
        items: pages,
    });

推荐答案

更新：对不起，对于不相关的例子我已经给了

你的页面在哪里[i] .update（this.record.data.images）; ？

您可以尝试以下操作 -

You can try the following -

var numberOfPages = this.record.data.length;
// Create pages for the carousel
var pages = [];
for (var i=0; i<numberOfPages; i++) {
    var tmp = new Ext.Component({
        id: 'page'+i,
        cls: 'page',
        tpl: '<tpl for=".">{imageurl}</tpl>'
    });
    tmp.update(this.record.data[i].images);
    pages.push(tmp);
}
