Ext4.1 Grid 分页查询

转载：http://blog.csdn.net/zyujie/article/details/16362747

最近用Ext4.1自己做了做项目的练习：把一些知识点，在这里记录下来了！

上面一个form表单，用作添加用户信息，包含了一些验证技巧。下面是一个带查询参数的分页Grid。

/**预加载的组件**/
Ext.require([
    'Ext.grid.*',
    'Ext.data.*',
    'Ext.util.*',
    'Ext.toolbar.Paging',
    'Ext.ModelManager',
    'Ext.tip.QuickTipManager',
    'Ext.layout.container.Border'
]);

Ext.onReady(function(){

    Ext.Ajax.timeout = 60000; // 60秒

    var pageSize = 10;

    //自定义正则表达式验证
    Ext.apply(Ext.form.VTypes,{
        phonecheck : function(val) {
            return /(^[1][358][0-9]{9}$)/.test(val);
        },
        phonecheckText : "号码不匹配!"
    },{
        usercheck : function(val) {
            //var reg = /(^[1][358][0-9]{9}$)/;
            //if(reg.test(val)==false){
            //  return false;
            //}
            return /^[a-z]+$/.test(val);
        },
        usercheckText : "格式不正确，只接受小写字母！"
    });

    var form = Ext.create('Ext.form.Panel', {
