Answer 1

如果你会jquery的话就很简单了，

$(document).ready(function(){

　　$('#cbTAll').bind("click",function(){

　　$("input[name='cbTeacher']").each(function(i,obj){

　　　　　　$(obj).attr("checked",$("#cbTAll").attr("checked"));

　　　　})

　　})

 

　　$('#cbSAll').bind("click",function(){

　　$("input[name='cbStudent']").each(function(i,obj){

　　　　　　$(obj).attr("checked",$("#cbSAll").attr("checked"));

　　　　})

　　})

 

})

Answer 2

每一个CheckBoxList组成生成客户端ID前掇都不一样，可以通过JS遍历ID名称是否包含当前组的。

Answer 3

怎么判断是否包含...当前组是指的什么。。。请问

Answer 4

@lovemc:你查看客户端生成的HTML源码，分析一个CheckBoxList生成的共同点。
