javascript数组只显示第一个字符

Question

我目前正在开发一个 ckeditor 插件，选择框从数据库中获取数据，我只能让第一个字符出现在选择框中。

get_pages.php

$query = selectQuery('
    SELECT title, pageID
    FROM  `page_info` 
    WHERE partnerID =?',array($partnerId));
$test = '';
foreach ($query as $key => $value) {
$test .= $value['title'].",";
}

Plugin.js

var pages = $.post(
        "/action/ac_select_pages.php",
        { pid: "1" },
        function(data) {
            return (data);         
    }
);

pages = pages.responseText.split(',');

我的变量:

pages: Array[31]  
    0: "Home"  
    1: "Control Panel"  
    2: "24/7 Support"  
    3: "Script / Databases"  
    4: "Last Announcment"  
    5: "E-mail: No Limit"  
    6: "Webmail & Push Mail"  

等等..

我如何制作我的选择框:

{
    type : 'select',
    id : 'moreinfo',
    label : 'Meerinfo Link',
    style : 'width:300px;',
    items : pages ,
    setup : function( element )
    {
    this.setValue( element.getAttribute( "moreinfo" ) );
    },
    commit : function( element )
    {
    var id = this.getValue();
    // If the field is non-empty, use its value to set the element's id attribute.
    if ( id )
    element.setAttribute( 'moreinfo', id );
    // If on editing the value was removed by the user, the id attribute needs to be removed.
    // http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.dom.element.html#removeAttribute
    else if ( !this.insertMode )
        element.removeAttribute( 'moreinfo' );
    }
}

如您所见，我只是将数组放在项目中，但它只显示第一个字符

那我做错了什么？

Answer 1

所以，总结一下......

split() 通过将字符串分成子字符串，将字符串对象拆分为字符串数组。

因此，大概您的 pages.responseText 看起来像这样:

Home,Control Panel,24/7 Support,Script / Databases,Last Announcment,E-mail: No Limit,Webmail & Push Mail

这意味着在执行 pages = pages.responseText.split(','); 之后，pages 看起来像这样(一个数组):

["Home", "Control Panel", "24/7 Support", "Script / Databases", "Last Announcment", "E-mail: No Limit", "Webmail & Push Mail"]

根据您的previous comment ，这有效:

var pages = [{0: 'Home', 1: 'Control Panel', ...}];

如您所见(具有多个值的数组):

["Home", "Control Panel", ...]

不与(一个对象具有多个属性的数组)相同:

[{0: 'Home', 1: 'Control Panel', ...}]

---

如果所有这些仍然正确，那么这样的事情应该可行:

var pagesObject = {};
for (var i=0, max=pages.length; i<max; i += 1) {
  pagesObject[i] = pages[i];
}

var correctPages = [ pagesObject ];
