<script type="text/javascript" src="src/bootstrap-3.3.7-dist/js/script.js"></script>
</body>
</html>


第三部分：java script   (本人在连接java script时连接如两个javascript文件：1、jquery-1.9.1.min.js不用写直接下载       2、script.js自己写的下面给出代码)

$(document).ready(function() {
    nav();
})

var idx;
var arr_offsetX = [0, 144, 233, 345, 400, 450];

function nav() {

    $(".topNavList a").hover(function() {

        idx = $(".topNavList a").index(this);

        $(".subNavWrapper").show();
        $(".activeLeft").show();
        $(".activeRight").show();

        var offsetXArrow = $(".topNavList a").eq(idx).position().left - 455;
        var w = $(".topNavList a").eq(idx).width() + 22;

        $(".topNavList a").eq(idx).addClass("activeTopNav");
        $(".activeLeft").css("left", offsetXArrow+'px');
        $(".activeRight").css("left", offsetXArrow+w+'px');

        $(".subNavSet div").eq(idx).show();

        if (idx == 0 || idx == 1 || idx == 3 || idx == 5) {
            $(".subNavSet .subNav").eq(idx).find("ul").css("width", "132px");
            $(".subNavSet .features").eq(idx).css("left", "195px");
        } else {
            $(".subNavSet .subNav").eq(idx).find("ul").css("width", "292px");
            $(".subNavSet .features").eq(idx).css("left", "315px");
        };
    }, function() {
        $(".subNavWrapper").hide();
        $(".activeLeft").hide();
        $(".activeRight").hide();
        $(".topNavList a").eq(idx).removeClass("activeTopNav");
        $(".subNavSet div").eq(idx).hide();
    })

    $(".subNavSet div").hover(function() {
        $(".subNavWrapper").show();
        $(".topNavList a").eq(idx).addClass("activeTopNav");
        $(".activeLeft").show();
        $(".activeRight").show();
        $(this).show();
    }, function() {
        $(".subNavWrapper").hide();
        $(".activeLeft").hide();
        $(".topNavList a").eq(idx).removeClass("activeTopNav");
        $(".activeRight").hide();
        $(this).hide();

    })

}

本文有借鉴网上给的代码模板。代码中有些使用到图片我有在****下载上传，

链接地址http://download.****.net/detail/qq_35164169/9903538。

初学者记得看自己代码中用到的图片路径，路径不一样会报错。
