JQuery实现选择的功能 ：全选、全不选、反选（代码）

这篇文章给大家介绍的文章内容是关于JQuery实现选择的功能 ：全选、全不选、反选，有很好的参考价值，希望可以帮助到有需要的朋友。

看重点就行了，最后面给一个网页完整的代码

代码实例：

    function selectStu() {
            $.ajax("StuList",{
                type:"post",
                data:{"method":"finList"},
                success:function(data){                    //循环遍历
                    $.each(data,function(index,obj){
                        $("#tab").append(                                "<tr>"+                                    //首先从数据库读出数据 因为数据库主键是学号，而且对学号进行操作
                                    //在input里面的值value添加数据中的学号
                                    "<td><input name=&#39;stu&#39; value=&#39;"+obj.stuNo+"&#39; type=&#39;checkbox&#39; /></td>"+
                                    "<td>"+obj.stuNo+"</td>"+
                                    "<td>"+obj.stuName+"</td>"+
                                    "<td>"+obj.stuSex+"</td>"+
                                    "<td>"+obj.stuAge+"</td>"+
                                    "<td>"+obj.score+"</td>"+
                                    "<td>"+obj.className+"</td>"+
                                "</tr>"
                        );
                    })
                }
            })
        }

全选：

///这个方法可以替代toggle()   toggle()在jQuery 1.9中已经移除
            //两个函数的绑定 
            var i=0;
            //全选
            $("#selectAll").on("click",function(){
                if(i==0){
                    //把所有复选框选中
                    $("#tab td :checkbox").prop("checked", true);
                    i=1;
                }else{
                    $("#tab td :checkbox").prop("checked", false);
                    i=0;
                }
                
            });

反选：

//反选
            $("#ReverseSelect").on("click",function(){
                
                $("#tab td :checkbox").each(function(){
                    //遍历所有复选框，然后取值进行 !非操作
                    $(this).prop("checked", !$(this).prop("checked"));
                })
            });

全选操作案例：

数据遍历出来：

点击全选：

反选操作案例：

首先选中几个

然后点击反选：
