基于jQuery实现首页悬浮框，如下图所示
在页面中引入jQuery.bay-window.js，jQuery.bay-window.js的代码如下：
!function($){ $.fn.autoMove = function(args){ //先定义一些工具函数判断边距 function isTop(pos, w_w, w_h, d_w, d_h){//飘窗到达上边距 return (pos.top<=0) ? true : false; } function isBottom(pos, w_w, w_h, d_w, d_h){//飘窗到达下边距 return (pos.top>=(w_h-d_h)) ? true : false; } function isLeft(pos, w_w, w_h, d_w, d_h){//飘窗到达左边距 return (pos.left<=0) ? true : false; } function isRight(pos, w_w, w_h, d_w, d_h){//飘窗到达右边距 return (pos.left>=(w_w-d_w)) ? true : false; } return this.each(function(){ var w_w = parseInt($(window).width()), w_h = parseInt($(window).height()), d_w = parseInt($(this).width()), d_h = parseInt($(this).height()), d_l = (w_w-d_w)/2, d_t = (w_h-d_h)/2, max_l = w_w - d_w; max_t = w_h - d_h; //位置及参数的初始化 var setobj = $.extend({startL:d_l, startT:d_t, angle:Math.PI/4, speed:100}, args); $(this).css({position: 'fixed', left: setobj['startL']+'px', top: setobj['startT']+'px'}); var position = {left: setobj['startL'], top: setobj['startT']};//飘窗位置对象 var that = $(this); var angle= setobj.angle; var time = 10;//控制飘窗运动效果，值越小越细腻 var step = setobj.speed * (time/1000);//计算运动步长 var decoration = {x:step*Math.cos(angle), y:step*Math.sin(angle)};//计算二维上的运动增量 var mvtid; $(window).on('resize', function(){//窗口大小变动时重新设置运动相关参数 w_w = parseInt($(window).width()); w_h = parseInt($(window).height()); max_l = w_w - d_w; max_t = w_h - d_h; }); function move(){ position.left += decoration.x; position.top += decoration.y; if(isLeft(position, w_w, w_h, d_w, d_h)||isRight(position, w_w, w_h, d_w, d_h)){ decoration.x = -1*decoration.x; } if(isRight(position, w_w, w_h, d_w, d_h)){ position.left = max_l; } if(isTop(position, w_w, w_h, d_w, d_h)||isBottom(position, w_w, w_h, d_w, d_h)){ decoration.y = -1*decoration.y; } if(isBottom(position, w_w, w_h, d_w, d_h)){ position.top = max_t; } //that.css({left:position.left, top:position.top}); that.stop().animate({left:position.left, top:position.top}, time);//改用jquery动画函数使其更加平滑 mvtid = setTimeout(move, time);//递归调用，使飘窗连续运动 } move();//触发动作 that.on('mouseenter', function(){ clearTimeout(mvtid) });//添加鼠标事件 that.on('mouseleave', function(){ move() }); }); }; //end plugin definition}(jQuery);接口获取悬浮框相关的数据
http("POST", "/School/detail", {"id":s_id}, function (e) { vm.piaoc = e.data; vm.$nextTick(function () { $('.automv').autoMove({angle:-Math.PI/4, speed:50}); $("body").on("click",".automv span",function(){ $(this).parent().find("a").removeAttr("href"); $(this).parent().hide(); }) }) })html页面引入相关html代码
<template v-if="piaoc != null"> <template v-if="piaoc.is_open_float_win == '1'"> <div class="automv" :> <span>×</span> <a :href="piaoc.open_float_url" rel="external nofollow" > <template v-if="piaoc.open_float_image"> <img :src="piaoc.open_float_image_name+'!y'" alt=""> </template> <template v-else> <img src="../image/piaochuang.jpg" alt=""> </template> </a> </div> </template> <template v-else> <div class="automv" ></div> </template></template>相关悬浮框的css
.automv{ width: 200px; height: 150px; z-index: 1032; position: relative;}.automv a{ display: block; width: 100%; height: 100%;}.automv a img{ width: 100%; height: 100%;}.automv span{ position: absolute; right: 3px; top: 3px; font-size: 26px; color: #fff; cursor: pointer; display: block; width: 20px; height: 20px; line-height: 20px; text-align: center;}.automv:hover span{ color: #fc87a3;}以上就是关于“jQuery如何实现首页悬浮框”这篇文章的内容，相信大家都有了一定的了解，希望小编分享的内容对大家有帮助，若想了解更多相关的知识内容，请关注编程网行业资讯频道。
