ExtJS字符串到Combobox [英] ExtJS String to Combobox

问题描述

我有一个php文件返回一个这样的字符串

I have a php file that returns a string like this

["item1","item2","item3","item4"]

我需要使用ExtJS创建一个组合框。选项必须是4个选项的项目。如果php链接 items.php ，我该如何做。为了使事情清楚我需要组合框displayField 和 valueField 有相同的值，如 item1 将是 displayField 和 valueField 。提前感谢！

I need to create a combobox with ExtJS. The options must be the items like 4 options. How would I do this if the php link is items.php. Just to make things clear I need the combobox displayField and valueField have the same values, like the item1 will be the displayField and the valueField. Thanks in advance!

该字符串不是Json格式的，我想它是数组存储。

P.S. the string is not Json formatted, I guess it's array store.

推荐答案

首先，我想你必须修改你的php脚本它至少返回字符串 [[item1]，[item2]，[item3]，[item4]] 。否则你必须创建自己的extjs阅读器或重写Ext.data.reader.Array.read方法。

Firstly, I think you have to modify your php script so that it returns string at least like this [["item1"],["item2"],["item3"],["item4"]]. Otherwise you will have to create your own extjs reader or override Ext.data.reader.Array.read method.

其次，你的商店应该是这样：

Secondly, your store should look like this:

var store = Ext.create('Ext.data.Store', {
  fields: ['item'],
  proxy: {
    type: 'ajax',
    url: '/items.php',
    reader: {
      type: 'array'
    }
  }
}

第三，你的组合配置应该看起来像这样： / p>

Thirdly, your combo config should look like this:

Ext.create('Ext.form.ComboBox', {
  store: store,
  displayField: 'item',
  valueField: 'item'
});

你决定使用你的原始php脚本无论如何你可以看看如何定义自己的阅读器（讨论了json阅读器，但你可以弄清楚如何在数组阅读器中实现该代码）

If you decide to use your original php script anyway you can take a look at how to define your own reader (There is json reader discussed, but you can figure out how to implement that code in your array reader)
