本文实例为大家分享了jQuery实现首页悬浮框的具体代码,供大家参考,具体内容如下
基于jQuery实现首页悬浮框,如下图所示
1、在页面中引入jQuery.bay-window.js,jQuery.bay-window.js的代码如下:
!function($){
/**
* Description: jquery飘窗插件,可自适应浏览器宽高的变化
* Author: ddqre12345
* CreateTime: 2017.5.3
* param: args={startL:default, startT:default, angle:-Math.PI/4, speed: 125}
* 参数说名: startL飘窗初始时距离左边的距离, startT飘窗初始化距离顶部的距离, angle飘窗初始运动方向, speed运动速度(px/s)
*/
$.fn.autoMove = function(args){
//先定义一些工具函数判断边距
function isTop(pos, w_w, w_h, d_w, d_h){//飘窗到达上边距
return (pos.top<=0) ? true : false;
}
function isBottom(pos, w_w, w_h, d_w, d_h){//飘窗到达下边距
return (pos.top>=(w_h-d_h)) ? true : false;
}
function isLeft(pos, w_w, w_h, d_w, d_h){//飘窗到达左边距
return (pos.left<=0) ? true : false;
}
function isRight(pos, w_w, w_h, d_w, d_h){//飘窗到达右边距
return (pos.left>=(w_w-d_w)) ? true : false;
}
return this.each(function(){
var w_w = parseInt($(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($(window).height());
max_l = w_w - d_w;
max_t = w_h - d_h;
});
function move(){
position.left += decoration.x;
position.top += decoration.y;
if(isLeft(position, w_w, w_h, d_w, d_h)||isRight(position, w_w, w_h, d_w, d_h)){
decoration.x = -1*decoration.x;
}
if(isRight(position, w_w, w_h, d_w, d_h)){
position.left = max_l;
}
if(isTop(position, w_w, w_h, d_w, d_h)||isBottom(position, w_w, w_h, d_w, d_h)){
decoration.y = -1*decoration.y;
}
if(isBottom(position, w_w, w_h, d_w, d_h)){
position.top = max_t;
}
//that.css({left:position.left, top:position.top});
that.stop().animate({left:position.left, top:position.top}, time);//改用jquery动画函数使其更加平滑
mvtid = setTimeout(move, time);//递归调用,使飘窗连续运动
}
move();//触发动作
that.on('mouseenter', function(){ clearTimeout(mvtid) });//添加鼠标事件
that.on('mouseleave', function(){ move() });
});
}; //end plugin definition
}(jQuery);
2、接口获取悬浮框相关的数据
http("POST", "/School/detail", {"id":s_id}, function (e) {
vm.piaoc = e.data;
vm.$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();
})
})
})
3、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" :style="'display: block;height:'+piaoc.open_float_height+';width:'+piaoc.open_float_width">
<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" style="display: none;"></div>
</template>
</template>
4、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;
}
