使用ajax从sanchtouch调用SOAP Webservice

Question

我有一个用sencha touch 1.1实现身份验证的表格

我尝试使用SOAP从webservices发送和获取数据，看起来我应该用ajax来做，但我不知道该怎么做。

<script type="text/javascript">
Ext.setup({
icon: 'icon.png',
tabletStartupScreen: 'tablet_startup.png',
phoneStartupScreen: 'phone_startup.png',

onReady: function() {

    Ext.regModel('User', {
        fields: [
            {name: 'name',     type: 'string'},
            {name: 'password', type: 'password'},
            {name: 'rank',     type: 'string'}
        ]
    });

     Ext.regModel('Ranks', {
        fields: [
            {name: 'rank',     type: 'string'},
            {name: 'title',    type: 'string'}

     });

    var ranksStore = new Ext.data.JsonStore({
