//-------------------------------------------------------------------------------
// 当然页面文件中还需要引入的文件如下：
// easyui.css 和其它页面用到的CSS文件
// jquery-1-8-3-min.js, easyui-lang-zh_CN.js, jquery-easyui-min.js, datagrid-detailview.js, 和其它页面用到的JS文件
//-------------------------------------------------------------------------------
// 结合SHIFT,CTRL,ALT键实现单选或多选
//-------------------------------------------------------------------------------
var KEY = { SHIFT:16, CTRL:17, ALT:18, DOWN:40, RIGHT:39, UP:38, LEFT:37};
var selectIndexs = {firstSelectRowIndex:0, lastSelectRowIndex:0};
var inputFlags = {isShiftDown:false, isCtrlDown:false, isAltDown:false}
function keyPress(event){//响应键盘按下事件
var e = event || window.event;
var code = e.keyCode | e.which | e.charCode;
switch(code) {
case KEY.SHIFT:
inputFlags.isShiftDown = true;
$('#dataListTable').datagrid('options').singleSelect = false;
break;
case KEY.CTRL:
inputFlags.isCtrlDown = true;
$('#dataListTable').datagrid('options').singleSelect = false;
break;
/*
case KEY.ALT:
inputFlags.isAltDown = true;
$('#dataListTable').datagrid('options').singleSelect = false;
break;
*/
default:
}
}
function keyRelease(event) { //响应键盘按键放开的事件
var e = event || window.event;
var code = e.keyCode | e.which | e.charCode;
switch(code) {
case KEY.SHIFT:
inputFlags.isShiftDown = false;
selectIndexs.firstSelectRowIndex = 0;
$('#dataListTable').datagrid('options').singleSelect = true;
break;
case KEY.CTRL:
inputFlags.isCtrlDown = false;
selectIndexs.firstSelectRowIndex = 0;
$('#dataListTable').datagrid('options').singleSelect = true;
break;
/*
case KEY.ALT:
inputFlags.isAltDown = false;
selectIndexs.firstSelectRowIndex = 0;
$('#dataListTable').datagrid('options').singleSelect = true;
break;
*/
default:
}
}
2，HTML代码,在页面增加加载数据的位置和在body中增加响应键盘事件：
<body class="body01" onkeydown="javascript:keyPress(event);" onkeyup="javascript:keyRelease(event);">
<!-- 数据加载存放位置 -->
<div>
<table id="dataListTable"></table>
</div>
3，在datagrid请求代码的onClickRow事件中增加操作代码，onClickRow单击事件如下：
onClickRow:function(index,row){
//-------------for TEST 结合SHIFT,CTRL,ALT键实现单选或多选----------------
if(index != selectIndexs.firstSelectRowIndex && !inputFlags.isShiftDown ){
selectIndexs.firstSelectRowIndex = index; //alert('firstSelectRowIndex, sfhit = ' + index);
}
if(inputFlags.isShiftDown ) {
$('#dataListTable').datagrid('clearSelections');
selectIndexs.lastSelectRowIndex = index;
var tempIndex = 0;
if(selectIndexs.firstSelectRowIndex > selectIndexs.lastSelectRowIndex ){
tempIndex = selectIndexs.firstSelectRowIndex;
selectIndexs.firstSelectRowIndex = selectIndexs.lastSelectRowIndex;
selectIndexs.lastSelectRowIndex = tempIndex;
}
for(var i = selectIndexs.firstSelectRowIndex ; i <= selectIndexs.lastSelectRowIndex ; i++){
$('#dataListTable').datagrid('selectRow', i);
}
}
//-------------for TEST 结合SHIFT,CTRL,ALT键实现单选或多选----------------
}
4，参考的datagrid请求代码：
;
$(function(){
$('#dataListTable').datagrid({
url:'xpath/jsonData01.json',
height:(screen.height == 900 ? 660 : 950),
nowrap:true,

return dataCon;
},
onExpandRow:function(index,row){ //展开事件

rowStyler:function(index,row){
/*

},
onClickRow:function(index,row){ //单击行事件
//---------for TEST 结合SHIFT,CTRL,ALT键实现单选或多选------------

}
if(inputFlags.isShiftDown ) {
$('#dataListTable').datagrid('clearSelections');
selectIndexs.lastSelectRowIndex = index;
var tempIndex = 0;
if(selectIndexs.firstSelectRowIndex > selectIndexs.lastSelectRowIndex ){
tempIndex = selectIndexs.firstSelectRowIndex;
selectIndexs.firstSelectRowIndex = selectIndexs.lastSelectRowIndex;
selectIndexs.lastSelectRowIndex = tempIndex;
}
for(var i = selectIndexs.firstSelectRowIndex ; i <= selectIndexs.lastSelectRowIndex ; i++){
$('#dataListTable').datagrid('selectRow', i);
}
}
//---------for TEST 结合SHIFT,CTRL,ALT键实现单选或多选------------
},
onLoadSuccess:function(data){
$('#dataListTable').datagrid('clearSelections');
},
onLoadError:function(){
//alert('error....');
}
});
//other variables or event initialize here
//-------------------------------------------
var p = $('#dataListTable').datagrid('getPager'); //个性化设置分页对象
$(p).pagination({

afterPageText:' 页，共{pages}页',
displayMsg:'当前{from} - {to}条, 共{total}条'

});
function formatterDate(objDate){ //格式化日期函数
var strDate = objDate.year;
strDate += '-' + objDate.month;
strDate += '-' + objDate.date;
