一、jsp頁面編寫`
check_btn：在相關check新增class屬性以便獲取相關的id值

<script>
function delManyStu(){
			var result="";
			var count=0;
			$(".check_btn").each(function(){    
			    if($(this).is(':checked')){
			    	result+=$(this).val();
			    	count++;
			    }else{}
			  });
			  //result=result.substring(0, result.length-1);
			//alert(result);
			window.location.href= "${ctx}/sys/delManyStu?ids="+result;
		}

</script>
 

二、Controller頁面

String delete = null;
			for(int i=0;i<ids.length();i++){//擷取id值得每個字元
			    String ss = String.valueOf(ids.charAt(i));
			    //System.out.println("字串擷取"+ss);
			    if (Character.isDigit(ss.charAt(0))) { //判斷是不是數字
			    	try {
						delete = studentService.delete(ss);
					} catch (Exception e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					}
			  }
			}
