這篇“jQuery如何實(shí)現(xiàn)首頁(yè)懸浮框”文章的知識(shí)點(diǎn)大部分人都不太理解,所以小編給大家總結(jié)了以下內(nèi)容,內(nèi)容詳細(xì),步驟清晰,具有一定的借鑒價(jià)值,希望大家閱讀完這篇文章能有所收獲,下面我們一起來(lái)看看這篇“jQuery如何實(shí)現(xiàn)首頁(yè)懸浮框”文章吧。
基于jQuery實(shí)現(xiàn)首頁(yè)懸浮框,如下圖所示
1、在頁(yè)面中引入jQuery.bay-window.js,jQuery.bay-window.js的代碼如下:
!function($){ /** * Description: jquery飄窗插件,可自適應(yīng)瀏覽器寬高的變化 * Author: ddqre12345 * CreateTime: 2017.5.3 * param: args={startL:default, startT:default, angle:-Math.PI/4, speed: 125} * 參數(shù)說(shuō)名: startL飄窗初始時(shí)距離左邊的距離, startT飄窗初始化距離頂部的距離, angle飄窗初始運(yùn)動(dòng)方向, speed運(yùn)動(dòng)速度(px/s) */ $.fn.autoMove = function(args){ //先定義一些工具函數(shù)判斷邊距 function isTop(pos, w_w, w_h, d_w, d_h){//飄窗到達(dá)上邊距 return (pos.top<=0) ? true : false; } function isBottom(pos, w_w, w_h, d_w, d_h){//飄窗到達(dá)下邊距 return (pos.top>=(w_h-d_h)) ? true : false; } function isLeft(pos, w_w, w_h, d_w, d_h){//飄窗到達(dá)左邊距 return (pos.left<=0) ? true : false; } function isRight(pos, w_w, w_h, d_w, d_h){//飄窗到達(dá)右邊距 return (pos.left>=(w_w-d_w)) ? true : false; } return this.each(function(){ var w_w = parseInt($(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; //位置及參數(shù)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']};//飄窗位置對(duì)象 var that = $(this); var angle= setobj.angle; var time = 10;//控制飄窗運(yùn)動(dòng)效果,值越小越細(xì)膩 var step = setobj.speed * (time/1000);//計(jì)算運(yùn)動(dòng)步長(zhǎng) var decoration = {x:step*Math.cos(angle), y:step*Math.sin(angle)};//計(jì)算二維上的運(yùn)動(dòng)增量 var mvtid; $(window).on('resize', function(){//窗口大小變動(dòng)時(shí)重新設(shè)置運(yùn)動(dòng)相關(guān)參數(shù) w_w = parseInt($(window).width()); w_h = parseInt($(window).height()); max_l = w_w - d_w; max_t = w_h - d_h; }); function move(){ position.left += decoration.x; position.top += decoration.y; if(isLeft(position, w_w, w_h, d_w, d_h)||isRight(position, w_w, w_h, d_w, d_h)){ decoration.x = -1*decoration.x; } if(isRight(position, w_w, w_h, d_w, d_h)){ position.left = max_l; } if(isTop(position, w_w, w_h, d_w, d_h)||isBottom(position, w_w, w_h, d_w, d_h)){ decoration.y = -1*decoration.y; } if(isBottom(position, w_w, w_h, d_w, d_h)){ position.top = max_t; } //that.css({left:position.left, top:position.top}); that.stop().animate({left:position.left, top:position.top}, time);//改用jquery動(dòng)畫函數(shù)使其更加平滑 mvtid = setTimeout(move, time);//遞歸調(diào)用,使飄窗連續(xù)運(yùn)動(dòng) } move();//觸發(fā)動(dòng)作 that.on('mouseenter', function(){ clearTimeout(mvtid) });//添加鼠標(biāo)事件 that.on('mouseleave', function(){ move() }); }); }; //end plugin definition }(jQuery);
2、接口獲取懸浮框相關(guān)的數(shù)據(jù)
http("POST", "/School/detail", {"id":s_id}, function (e) { vm.piaoc = e.data; vm.$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頁(yè)面引入相關(guān)html代碼
<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>
4、相關(guān)懸浮框的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; }
