ExtJs 4 Combobox缺少配置选项hiddenName [英] ExtJs 4 Combobox missing config option hiddenName

问题描述

我试图创建一个ExtJs版本4 ComboBox，它将发布valueField而不是displayValue。以前的版本将是在ComboBox的配置中设置'hiddenName'选项，但我似乎无法找到它在v 4或等效的东西。此外，这不是在ExtJs表单面板中。组合框以纯HTML形式呈现

I'm trying to create an ExtJs version 4 ComboBox that will post the valueField and not the displayValue. Prior version would be to set the 'hiddenName' option in the config of ComboBox, but I can't seem to find it in v 4 or something equivalent. Also, this is NOT in an ExtJs form panel. The combobox is being rendered inside a plain html form

//My Code

new Ext.form.ComboBox({
    renderTo: 'my_div',
    store: new Ext.data.SimpleStore({
        fields: ['value', 'name'],
        data: [['1', 'A'], ['2', 'B'], ['3', 'C']]
    }),
    name: 'letter',
    hiddenName: 'letter_id',
    hiddenValue : '0',
    displayField: 'name',
    valueField: 'value',
    mode: 'local'
});



//  The value of the form POST when I selected 'A'
"letter=A"

//  This is what I want
"letter=1"

推荐答案

只是为了信息.... Extjs团队改进了每个元素的配置。

和在 combobox 不再有< c $ c> hiddenName

您曾经阅读过这？尝试导航到第52页，都会产生类似的结果...

just for info.... Extjs team has improved the "configs" for every element.
And in combobox there is no longer hiddenName
have you ever read this? try to navigate to page 52, both will yield similar results...

var itemForm = Ext.create('Ext.form.FormPanel',{
    title: 'Simple Form',
    renderTo :Ext.getBody(),
    url :'test.php',
    items:[
        new Ext.form.ComboBox({
            store: new Ext.data.SimpleStore({
                fields: ['value', 'name'],
                data: [['1', 'A'], ['2', 'B'], ['3', 'C']]
            }),
            name: 'letter',
            displayField: 'name',
            valueField: 'value',
        })]
});

它发送 letter = 1 ..

可能是其他地方的错误。

when i run this itemForm.getForm().submit() it send letter = 1..
maybe the error is somewhere else ..
