1、页面中增加监听

2、引入JS

//-------------------------------------------------------------------------------// 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;  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;  break; default:    }}

3、在datagrid中加入

 onCheckRow :function(checked,data,rowid,rowdata){     //-------------for 结合SHIFT键实现单选或多选---------------     if(!inputFlags.isShiftDown ){      selectIndexs.firstSelectRowIndex = data.__index;     }     if(inputFlags.isShiftDown ) {      selectIndexs.lastSelectRowIndex = data.__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++){       grid.select(i);      }     }     //-------------for 结合SHIFT键实现单选或多选----------------   },
