                var text = $(this).text();
                var a1 = '.modal input[name="';
                var a2 = '"]';
                var temp = a1 + n + a2;
                $(temp).val(text);

    <style>
        .hide{
            display: none;

        $('.content').children("[b='"+ target + "']").removeClass('hide').siblings().addClass('hide');
    });
</script>
</body>
</html>

    4、标题

    　　　　内容：

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .header{
            background-color: black;
            color: wheat;
        }
        .content{
            min-height: 50px;
        }
        .hide{
            display: none;
        }
    </style>
</head>
<body>
    <div style="height:400px; 200px;border: 1px solid #dddddd">
        <div class="item">
            <div class="header">标题一</div>
            <div id="i1" class="content hide">内容</div>
        </div>
        <div class="item">
            <div class="header">标题二</div>
            <div class="content hide">内容</div>
        </div>

        <div class="item">
            <div class="header">标题三</div>
            <div class="content hide">内容</div>
        </div>
    </div>
    <script src="jquery-1.12.4.js"></script>
    <script>
        $('.header').click(function(){
            // 当前点击的标签 $(this)
            // 获取某个标签的下一个标签
            // 获取某个标签的父标签
            // 获取所有的兄弟标签
            // 添加样式和移除样式
            // $('.i1').addClass('hide')
            // $('#i1').removeClass('hide')
            // var v = $("this + div");
            // $("label + input")
            // console.log(v);
            //
            // $("afsldkfja;skjdf;aksdjf")

            // 筛选器
            /*
            $(this).next()      下一个
            $(this).prev()      上一个
            $(this).parent()    父
            $(this).children()  孩子
            $('#i1').siblings() 兄弟
            $('#i1').find('#i1') 子子孙孙中查找
            // . . .
            //
            $('#i1').addClass(..)
            $('#i1').removeClass(..)
            */

            // 链式编程
            // $(...).click(function(){
            //     this..
            // })


//            $(this).next().removeClass('hide');
//            $(this).parent().siblings().find('.content').addClass('hide')

            $(this).next().removeClass('hide').parent().siblings().find('.content').addClass('hide')

        })
    </script>
</body>
</html>

    5、jquery超链接

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <a onclick="return ClickOn()"  href="http://www.oldboyedu.com">走你1</a>

    <a id="i1" href="http://www.oldboyedu.com">走你2</a>
    <script src="jquery-1.12.4.js"></script>
    <script>
        function ClickOn() {
            alert(123);
            return true;
        }
        $('#i1').click(function () {
            alert(456);
            return false;
        })
    </script>
</body>
</html>

    6、有规则添加

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <input id="t1" type="text" />
    <input id="a1" type="button" value="添加" />

    <ul id="u1">
        <li>1</li>
        <li>2</li>
    </ul>
<script src="jquery-1.12.4.js"></script>
    <script>
        $('#a1').click(function () {
            var v = $('#t1').val();
            var temp = "<li>" + v + "</li>";
            $('#u1').append(temp);
        });

//        $('ul li').click(function () {
//            var v = $(this).text();
//            alert(v);
//        })

//        $('ul li').bind('click',function () {
//            var v = $(this).text();
//            alert(v);
//        })

//        $('ul li').on('click', function () {
//            var v = $(this).text();
//            alert(v);
//        })

        $('ul').delegate('li','click',function () {
            var v = $(this).text();
            alert(v);
        })

    </script>
</body>
</html>

    7、<div></div>鼠标可随意拖动

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
 <div style="border: 1px solid #ddd; 700px;position: absolute;">
        <div id="title" style="background-color: black;height: 40px;"></div>
        <div style="height: 500px;">
            <div class="ziti" style="float: left;margin-left: 200px"></div>
        </div>
 </div>
<script type="text/javascript" src="jquery-1.12.4.js"></script>
<script>
    $(function(){
        $('#title').mouseover(function(){
            $(this).css('cursor','move');
        });
        $("#title").mousedown(function(e){
            //console.log($(this).offset());
            var _event = e || window.event;
            var ord_x = _event.clientX;
            var ord_y = _event.clientY;

            var parent_left = $(this).parent().offset().left;
            var parent_top = $(this).parent().offset().top;

            $('#title').on('mousemove', function(e){
                var _new_event = e || window.event;
                var new_x = _new_event.clientX;
                var new_y = _new_event.clientY;

                var x = parent_left + (new_x - ord_x);
                var y = parent_top + (new_y - ord_y);

                $(this).parent().css('left',x+'px');
                $(this).parent().css('top',y+'px');

            })
        });
        $("#title").mouseup(function(){
            $("#title").off('mousemove');
        });
    })
</script>
</body>
</html>
