页面在初始化加载数据较多时会非常耗时，如果只加载表格，用户再根据自己的需要通过条件查询数据，就会节约一些时间，提高用户体验，所以在初始化datagrid时想只加载表格不加载数据，做到数据与表格加载分离的效果。
经过实验发现，使用.datagrid（）方法时，参数中只要有URL存在，都会自动调用一次加载数据，可设置url参数为null，则加载表格时就不会向后台发出请求；但是此时如果用户想重置页面条件，重新加载页面时，由于没有请求后台，只加载表格，则会发生页面条件清空，表格数据还在或者表格数据为空分页展示的记录却不为0的现象，所以也需要重置数据和分页参数，具体代码如下：
[javascript] view plain copy
/**
* dataGrid初始化表格
* @param id datagrid的id
* @param column 展示的列名
* @param opt 设置自定义datagrid属性
*/
function commonInitDataGrid(id, column, opt){
var initData =
{
"code":100,
"msg":"",
"data":{"totalDataCount":0,"totalPageCount":0,"list":[],"properties":{"footer": []}}
}
//校验参数
if(isEmpty(id) || isEmpty(column)){
jQuery.messager.alert("系统提示", "系统错误，请联系技术人员！")
return
}
//默认属性
var defaultOpt= {
"url": null,
"method": 'POST', //请求方式
"columns": column,
"width": document.body.clientWidth < 756 ? 756 - 18 : document.body.clientWidth - 18,
"remoteSort": false,
"rownumbers": true,
"pagination": true,
"showFooter": true,
"fitColumns": true,
"pageNumber": 1,
"pageSize": 20,
"pageList": [10, 20, 30, 50, 100],
"singleSelect": true,
"striped": true,
"loadFilter": function (result) {
if (result.code == "100") {
//解析json结果集，返回给datagrid
var obj =
{
"total": result.data.totalDataCount,
"rows": result.data.list,
"footer": result.data.properties.footer
}
return obj
} else {
jQuery.messager.alert("系统提示", result.msg)
return false
}
}
}
if(!isEmpty(opt)){
//替换自定义属性
$.extend(defaultOpt, opt)
}
//把属性与事件放到表格中，进行初始化
$("#" + id).datagrid(defaultOpt)
$("#" + id).datagrid('loadData', initData)
}
说明：1.设置URL为null后，则每次调用此方法都只会加载表格，不加载数据，调用此方法时就不需要再调用此方法之前设置URL了；
2.pageSize的参数不在pageList之中时，页面分页会默认取pageList中的第一个参数，此时pageSize设置无效。
3.loadFilter方法是为了处理后台返回的结果，并自动传给datagrid进行处理然后展示在页面
如果要达到这个功能呢，必须学几个部分：1）：是html语言，至少得学会select怎么编。。<select id="lists"><option value="?">?</option></select>
2）：数据库语言，你得能够查询数据库，从数据库中选出与你内容相近的东东
3）：脚本语言(script)
4）：ajax 时时通信脚本
学会了这几个呢，基本上，其它的都不是问题了！
