iOS中的webView加载HTML_html/css_WEB-ITnose

Jun 21, 2016 am 08:57 AM

在日常开发中,我们为了效率会用到很多很多的 WebView,比如在做某个明细页面的时候我们返回给你的可能是一个 html字符串,我们就需要将当前字符串展示到 webView上面,所以我们对 HTML标签需要有一定的认识,下面我们来一起用 html标签和 JS写一个打地鼠游戏 ,这里我们主要讲解 HTML标签的书写,只要如何和 webView适配涉及到响应式布局我们下次讲解:

1、首先我们先新建一个 html文件

2 完整 html标签并且设置编码格式为 UTF-8

3 在 body里面增加十只老鼠图片,并且增加点击事件,当点击老鼠后触发 JS函数 onclick="addScore(this);",代码如下:

        <img  src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg'   style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >        <img  src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg'   style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >       <img  src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg'   style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >       <img  src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg'   style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >      <img  src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg'   style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >          <img  src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg'   style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >      <img  src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg'   style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >      <img  src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg'   style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >      <img  src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg'   style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >      <img  src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg'   style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >

4 先将所有的老鼠图片放入数组中,然后开启定时器,每秒调用两次该方法,并且随机显示八个老鼠图片

//展示老鼠                   function showMouse(){                                              //隐藏所有的老鼠                       hideAll();                       //控制点击次数                       times++;                       //超过20此结束点击                       if(times>20){                           window.clearInterval(timer);                           alert("游戏结束,得分"+score+"分");                           return;                       }                                              //获取所有的老鼠                       var imgs=document.getElementsByTagName("img");                                              //随机的显示八只老鼠                       for(var i=0;i<8;i++){                           var tem=Math.random()*10;                           tem= Math.round(tem);                           var node=imgs[tem]                                                      node.style.display="";                                                }                   }               //隐藏所有老鼠              function hideAll(){                  var imgs=document.getElementsByTagName("img");                                   for(var i=0 ;i<img s.length;i++){                      var tem=imgs[i];                      tem.style.display="none";                                   }              }</pre alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >    <p>5 每次点击我们需要隐藏当前的图片,并且增加分数,每点击一次老鼠增加一分</p>    <pre class='brush:php;toolbar:false;'>  //增加分数            function addScore(cell){                cell.style.display="none";                score++;                document.getElementById("label").innerHTML=score+"分数";            }
