easyui datagrid综合功能demo实现

实现功能：行内修改，批量行内添加，多条件查询；（查询当中不是联查）

JavaScript：

$(function(){

<span style="font-family: Arial, Helvetica, sans-serif;">                    initGrid8();</span>

<span style="font-family: Arial, Helvetica, sans-serif;">                     });</span>

//定义初始化方法
function initGrid8() {
//初始化comblbox数据
initComoboxData();
//给姓名录入框添加清楚图标
$('#txtname').textbox().textbox('addClearBtn', 'icon-clear');
//为日期组合框设置默认值
var now = new Date();
var time1 = now.getFullYear()-50 + "-" + (now.getMonth()+1).toString() + "-" + now.getDate().toString();
var time2 = now.getFullYear() + "-" + (now.getMonth() + 1).toString() + "-" + now.getDate().toString();
$("#datebox1").datebox('setValue', time1);
$("#datebox2").datebox('setValue', time2);
//各种查询
$("#btn_save").linkbutton({ onClick: function () { grid8Accept(); return false;  }});
//$("#btn_search").linkbutton({ onClick: function () { doSearch(); } });
$("#cmbGender").combobox({ onChange: function () { doSearch(); } });
//$("#deptCombobox8").combobox({ onChange: function () { doSearch(); } });
//$("#deptCombobox8").combobox({ onChange: function () { alert(); doSearch(); } });
//$("#datebox1").datebox({ onChange: function (nValue, oValue) { if (oValue != null && oValue != '') { doSearch(); }}});
//主体：
