我使用Extjs 3创建一个表单面板，我想创建一个字段来放置一个IP地址v4，就像我有4个方格来放4个数字。谢谢你的帮助

我已将Robert B. Williams版本用于IP领域。只需几个小时，您就可以将其更改为适合V4 IP。

这是代码：

/**
* @class Ext.ux.form.TimeField
* @extends Ext.ux.form.FieldPanel
* This class creates a time field using spinners.
* @license: BSD
* @author: Robert B. Williams (extjs id: vtswingkid)
* @constructor
* Creates a new FieldPanel
* @param {Object} config Configuration options
*/
Ext.namespace("Ext.ux.form");
Ext.ux.form.IpField = Ext.extend(Ext.ux.form.FieldPanel, {
border: false,
baseCls: null,
layout: 'table',
token: '.',
value: '192.168.0.1',
layoutConfig: {
    columns: 7
},
width: 180,
// private
defaults:{
    maskRe: /[0-9]/,
    maxLength: 3,
    listeners: {
        'focus': function(f){
            f.selectText();
        }
    }
},
initComponent: function()
{
    this.items = [{
        xtype:'numberfield',
        width:40,
        name: this.name + '0'
    }, {
        html: '.',
        baseCls: null,
        bodyStyle: 'font-weight: bold; font-size-adjust: .9',
        border: false
    }, {
        xtype:'numberfield',
        width:40,
        name: this.name + '1'
    }, {
        html: '.',
        baseCls: null,
        bodyStyle: 'font-weight: bold; font-size-adjust: .9',
        border: false
    }, {
        xtype:'numberfield',
        width:40,
        name: this.name + '2'
    }, {
        html: '.',
        baseCls: null,
        bodyStyle: 'font-weight: bold; font-size-adjust: .9',
        border: false
    }, {
        xtype:'numberfield',
        width:40,
        name: this.name + '3'
    }]
    Ext.ux.form.IpField.superclass.initComponent.call(this);
}
});
Ext.reg('uxipfield', Ext.ux.form.IpField);

带有Extjs的IP地址v4的表单字段
