前端网站html生成腾讯地图和卫星地图教程前端html生成网站地图，除了使用百度地图外还可以使用腾讯地图来生成。使用百度地图案例，参考：网站如何创建百度地图显示地理位置以下是前端网站html生成腾讯地图和卫星地图教程，供新手参考：1、首先打开腾讯地图坐标拾取器：https://lbs.qq.com/tool/getpoint/index.html2、复制坐标：23.124825,113.372164，如下图3、显示地图代码：<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>腾讯地图-地图参数使用示例</title> <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no" /> <script charset="utf-8" src="http://map.qq.com/api/js?v=2.exp&key=5WNBZ-2JYR6-SPUSL-M3WGH-U4KDT-K2FYV"></script> <style type="text/css"> /*#map span,#map a ,.smnoprint{ display: none!important; } */ #map{ width: 100%; min-height:600px; } </style> </head> <body onload="init()"> <div id="map"></div> <script> function init() { //腾讯坐标拾取器或得中心点 var center = new qq.maps.LatLng(23.124825,113.372164); var map = new qq.maps.Map(document.getElementById('map'),{ center: center, zoom: 16, //绽放控件 zoomControl: false, //平移控件 panControl: false, }); //创建一个Marker var marker = new qq.maps.Marker({ //设置Marker的位置坐标 position: new qq.maps.LatLng(23.124825,113.372164), //设置显示Marker的地图 map: map }); ////设置Marker自定义图标的属性，size是图标尺寸，该尺寸为显示图标的实际尺寸，origin是切图坐标，该坐标是相对于图片左上角默认为（0,0）的相对像素坐标，anchor是锚点坐标，描述经纬度点对应图标中的位置 var anchor = new qq.maps.Point(15, 10), size = new qq.maps.Size(32, 32), origin = new qq.maps.Point(0, 0), icon = new qq.maps.MarkerImage( "/images/map.svg", size, origin, anchor ); marker.setIcon(icon); //添加信息窗口 var detail = '<div >'+ '<h3>天河软件园</h3>电话：020-0000-0000<br>地址：广东省广州市天河区科韵路200号</div>'; var info = new qq.maps.InfoWindow({ map: map }); //获取标记的可拖动属性 info.open(); info.setContent(detail); info.setPosition(marker.getPosition()); //标记Marker点击事件 qq.maps.event.addListener(marker, 'click', function() { info.open(); info.setContent(detail); info.setPosition(marker.getPosition()); }); } </script> </body> </html>4、显示地图：如下，地图上显示的电话，地址，都可以根据自己的实际设置文字

H5微信9宫格抽奖+概率设置 9宫格抽奖百度找了很久也没有找到可以设置中奖概率的，后面找到一篇文章，结合后端PHP设置的中奖概率。以下是个例子，供大家参考和使用。1、抽奖界面代码：<!doctype html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta content="width=device-width,initial-scale=1.0,maximum-scale=1.0,user-scalable=0" name="viewport"> <meta content="yes" name="apple-mobile-web-app-capable"> <meta content="black" name="apple-mobile-web-app-status-bar-style"> <script type="text/javascript" src="https://libs.baidu.com/jquery/2.1.1/jquery.min.js"></script> <link rel="stylesheet" type="text/css" href="https://www.tpxhm.com/fdetail/index.css?" /> </head> <script type="text/javascript"> function fontSize(){ var deviceWidth=document.documentElement.clientWidth>640?640:document.documentElement.clientWidth; document.documentElement.style.fontSize=(deviceWidth/25)+"px"; } fontSize(); window.onresize=fontSize; </script> <body> <div class="p1"> <div id="lottery" class="wxicke"> <style> .wxicke{ position: relative; } .zpbg_04{ width: 100%; height: 100%; position: absolute; left: 0px; top: 0px;} </style> <table border="0" cellpadding="0" cellspacing="0"> <tr> <td class="lottery-unit lottery-unit-0"><span></span><div class="mask"></div></td> <td class="lottery-unit lottery-unit-1"><span></span><div class="mask"></div></td> <td class="lottery-unit lottery-unit-2"><span></span><div class="mask"></div></td> </tr> <tr> <td class="lottery-unit lottery-unit-4"><span></span><div class="mask"></div></td> <td colspan="2" class="btndon"><a><img src="https://www.tpxhm.com/fdetail/images/sz_03.png" alt="" class="c_stsn"></a></td> <td class="lottery-unit lottery-unit-5"><span></span><div class="mask"></div></td> </tr> <tr> <td class="lottery-unit lottery-unit-6"><span></span><div class="mask"></div></td> <td class="lottery-unit lottery-unit-7"><span></span><div class="mask"></div></td> <td class="lottery-unit lottery-unit-8"><span></span><div class="mask"></div></td> </tr> </table> </div> </div>  <div class="resful"> <div class="resfulbox"> <img src="https://www.tpxhm.com/fdetail/images/close.png" alt="" class="bigclose" onclick="bigclose()"> <h1>获得<span>【</span><span class="pronum"></span><span>】</span>一份</h1> <div class="forms"> <label for="">姓名：</label> <input type="text" class="txun_name" /> <label for="">手机：</label> <input type="text" class="txun_tel" /> <button type="button" class="wxapisub">登记领取</button> </div> </div> </div> <script> /* 抽奖 */ var lottery={ index:-1, //当前转动到哪个位置，起点位置 count:0, //总共有多少个位置 timer:0, //setTimeout的ID，用clearTimeout清除 speed:20, //初始转动速度 times:0, //转动次数 cycle:50, //转动基本次数：即至少需要转动多少次再进入抽奖环节 prize:-1, //中奖位置 prize:0, //中奖位置 prizes:0, //中奖位置自定义+ prizesName:'', //奖项自定义+ pass: [0,1,2], // 跳过的位置，从0开始 init:function(id){ if ($("#"+id).find(".lottery-unit").length>0) { $lottery = $("#"+id); $units = $lottery.find(".lottery-unit"); this.obj = $lottery; this.count = $units.length; $lottery.find(".lottery-unit-"+this.index).addClass("active"); }; }, roll:function(){ var index = this.index; var count = this.count; var lottery = this.obj; $(lottery).find(".lottery-unit-"+index).removeClass("active"); index += 1; if (index>count-1) { index = 0; }; $(lottery).find(".lottery-unit-"+index).addClass("active"); this.index=index; return false; }, stop:function(index){ this.prize=index; return false; } }; // 检查中奖位置是否可用 function check(index) { var result = true; for(var i = 0, len = lottery.pass.length; i < len; i++) { if (index == lottery.pass[i]) { result = false; break; } } return result; } function roll(){ lottery.times += 1; lottery.roll();//转动过程调用的是lottery的roll方法，这里是第一次调用初始化 // 中奖 lottery.prize =lottery.prizes if (lottery.times > lottery.cycle+5 && lottery.prize==lottery.index) { clearTimeout(lottery.timer); lottery.prize=-1; lottery.times=0; click=false; // console.log($('.active').text()) console.log(lottery.prize) console.log(lottery.prizesName) // 获得写入缓存 localStorage.setItem('awards',lottery.prizesName) setTimeout('swr()',1000); // swr() }else{ if (lottery.times<lottery.cycle) { lottery.speed -= 5; } // 基本转动已结束，开始计算中奖位置 else if(lottery.times==lottery.cycle) { var index = Math.random()*(lottery.count)|0; while(!check(index)) { index = Math.random()*(lottery.count)|0; } lottery.prize = index; }else{ // 转动次数大于基本次数+10，且（转动位置在最后一个中奖位置是第一个）或（下一个位置就是中奖位置）开始进入抽奖环节的最后阶段，转动速度更慢 if (lottery.times > lottery.cycle+5 && ((lottery.prize==0 && lottery.index==9) || lottery.prize==lottery.index+1)) { lottery.speed += 25; }else{ // 刚进入抽奖环节，减慢速度 lottery.speed += 5; } } if (lottery.speed<15) { lottery.speed=15; }; //console.log(lottery.times+'^^^^^^'+lottery.speed+'^^^^^^^'+lottery.prize); lottery.timer = setTimeout(roll,lottery.speed);//循环调用 } return false; } var click=false; window.onload=function(){ lottery.init('lottery'); $("#lottery a").click(function(){ if (click) {//click控制一次抽奖过程中不能重复点击抽奖按钮，后面的点击不响应 return false; }else{ $('.c_stsn').css('display','none') //点击抽奖关闭手指 lottery.speed=25; roll(); //转圈过程不响应click事件，会将click置为false click=true; //一次抽奖完成后，设置click为true，可继续抽奖 $.get("http://www.example.com/gl/", function(data) { //获取奖品 // console.log(data) lottery.prizes =data.id; lottery.prizesName = data.prize }, "json") return false; } }); }; function swr(){ var active=localStorage.getItem('awards'); $('.resful').css('visibility','visible') $('.pronum').text(active);//中奖结果 } </script> </body> </html>2、后端中奖概率设置。算法：计算总奖品概率，v即为概率，执行方法之后会返回中奖奖品名称及idpublic function gl(){ $prize_arr = [ '0' => ['id' => 1, 'prize' => '奖品1', 'v' => 20], '1' => ['id' => 2, 'prize' => '奖品2', 'v' => 10], '2' => ['id' => 3, 'prize' => '奖品3', 'v' => 20], '3' => ['id' => 4, 'prize' => '奖品4', 'v' => 5], '4' => ['id' => 5, 'prize' => '奖品5', 'v' => 19], '5' => ['id' => 6, 'prize' => '奖品6', 'v' => 5], '6' => ['id' => 7, 'prize' => '奖品7', 'v' => 10], '7' => ['id' => 8, 'prize' => '奖品8', 'v' => 10], ]; foreach ($prize_arr as $key => $val) { $arr[$val['id']] = $val['v']; } $rid = $this->get_prize($arr); //根据概率获取奖项id $data = $prize_arr[$rid-1]; return json($data); } public function get_prize($proArr) { $result = ''; //概率数组的总概率精度 $proSum = array_sum($proArr); //概率数组循环 foreach ($proArr as $key => $proCur) { $randNum = mt_rand(1, $proSum); if ($randNum <= $proCur) { $result = $key; break; } else { $proSum -= $proCur;
