EasyUI比较常用，其中的datagrid比较复杂，它有其中有load,reload,loadData这三个方法，它们都有相同的功能，都是加载数据的，但又有区别。
load方法，比如我已经定义一个datagrid的id为grid，那这个方法的使用方式为
$(“#grid”).datagrid(“load”,{ });
它的参数为一个json对象，里面写的是你要传输的参数的键值对，调用这个方法来加载数据的时候，它传给后台的分页信息是从第一页开始的。
reload方法，使用方式也跟load的一样
$(“#grid”).datagrid(“reload”,{ });
看它的名字应该就可以知道它的做用了，没错，它跟load一样有加载数据功能，也一样的传参数，但它传给后台的分布信息是当前的页码，就是实现刷新当前页的功能。
loadData方法，这个方法有比较大的不同，首先它加载的本地数据，就是不会跟后台什么的有交互，它的使用方式是
$(“#grid”).datagrid(“loadData”,{ “total”:”30″,rows:[] });
看到没，它是比较灵活的，可以设置分页信息的，total就是行数嘛，当然你也可以设置它的当前页，而它那个rows属性设的就是你所要加载的行的集合。
var bbc="";
$(function(){
$("#test").datagrid({
loadFilter: function (data){bbc=data;return bbc;},
/*loadFilter: function (data) {
for (var i = 0; i < data.rows.length; i++) {
for (var att in data.rows[i]) {
if (typeof (data.rows[i][att]) == "string") {
data.rows[i][att] = data.rows[i][att].replace(/</g, "<").replace(/>/g, ">");
}
}
}
return data;

loadData ： 参数(data) 加载本地数据，旧的行会被移除。
loadFilter : 类型(function) 返回过滤的数据去显示。这个函数需要一个参数'data'，表示原始数据。你可以把原始数据变成标准数据格式，此函数必须返回标准数据对象，含有 'total' 和 'rows' 特性。
