本篇文章主要介紹了JS傳參及動(dòng)態(tài)修改頁(yè)面布局的相關(guān)知識(shí)。具有很好的參考價(jià)值。下面跟著小編一起來(lái)看下吧

一個(gè)關(guān)于JS傳參及動(dòng)態(tài)修改頁(yè)面布局的簡(jiǎn)單小例子。

HTML:

<!DOCTYPE HTML>
<html>
 <head>
  <meta charset="utf-8" />
  <title></title>
  <link rel="stylesheet" href="css/style.css" rel="external nofollow" />
 </head>
 <body>
  <div id="button"><h1>請(qǐng)為下面的DIV設(shè)置樣式：</h1><div>點(diǎn)擊設(shè)置</div></div>
  <div id="set">
   <div class="set1"><span>請(qǐng)選擇背景色：</span><span onclick="cl('red')">紅</span><span onclick="cl('yellow')">黃</span><span onclick="cl('blue')">藍(lán)</span></div>
   <div class="set2"><span>請(qǐng)選擇寬(px)：</span><span onclick="wd(200)">200</span><span onclick="wd(300)">300</span><span onclick="wd(400)">400</span></div>
   <div class="set2"><span>請(qǐng)選擇高(px)：</span><span onclick="hd(200)">200</span><span onclick="hd(300)">300</span><span onclick="hd(400)">400</span></div>
   <span class="btn" onclick="reset()">恢復(fù)</span>
   <span class="btn" onclick="apply()">確定</span>
  </div>
  <div id="box"></div>
  <script type="text/javascript" src="js/js.js"></script>
 </body>
</html>

CSS:

/*top:26%; left:40%;*/
#box{width:100px; height: 100px; border:4px black solid;margin-top:100px;}
#button div{background: red; width:100px; height:40px; float:left; color:white; text-align: center; line-height: 40px; cursor: pointer;}
#set{width:20%; height:28%; border:15px rgb(156,148,156) solid; background:white; position: absolute; top:300px; left:300px; box-shadow: 0 0 8px gray; display:none;}
#set div{height: 40px; margin: 20px auto;}
#set div span{width:45px; height:40px; display:block; float:left; margin-left:10px; color:white; line-height:40px; text-align:center; cursor:pointer;}
#set div span:hover{border:1px black solid}
#set div span:nth-of-type(1){width:auto; color:black; font:18px/40px "微軟雅黑"; margin-left:12%; border:none; cursor:auto;}  /*:nth-of-type()表示同級(jí)同容器下該種類(lèi)型的第幾個(gè)標(biāo)簽括號(hào)內(nèi)的數(shù)字即指第幾個(gè)，從1開(kāi)始*/
#set .set1 span:nth-of-type(2){background:rgb(230,46,0); margin-left:5px;}
#set .set1 span:nth-of-type(2):hover{background:red}
#set .set1 span:nth-of-type(3){background:rgb(239,189,0)}
#set .set1 span:nth-of-type(3):hover{background:yellow}
#set .set1 span:nth-of-type(4){background:rgb(90,148,239)}
#set .set1 span:nth-of-type(4):hover{background:blue}
#set .set2 span{border:1px rgb(198,198,198) solid; color:rgb(136,140,143)}
#set .set2 span:nth-of-type(1):hover{background:white;}
#set .set2 span:nth-of-type(2){background:rgb(239,239,239); margin-left:5px;}
#set .set2 span:nth-of-type(3){background:rgb(239,239,239)}
#set .set2 span:nth-of-type(4){background:rgb(239,239,239)}
#set .set2 span:hover{background:rgb(239,148,0)}
#set .btn{width:60px; height:30px; background:#002952; color:white; display:block; float:left; margin-left:10px; margin-top:10px; text-align:center; line-height:30px; cursor:pointer;}
#set span:nth-of-type(1){margin-left:32%;}

JS:

onload = function(){           //加載完畢給div添加點(diǎn)擊事件，可以不這么做，像下面的reset / apply一樣建立一個(gè)函數(shù)并在該div上寫(xiě)上Onclick點(diǎn)擊事件調(diào)用函數(shù)即可
 var btn = document.getElementById('button').getElementsByTagName('div');
 btn[0].onclick = function(){
  document.getElementById('set').style.display = 'block';
 }
}
var box = document.getElementById('box');     //建立全局變量獲取DIV對(duì)象
function wd(x){            //改變寬度
 box.style.width = x + 'px';
}

function hd(x){           //改變高度
 box.style.height = x + 'px';
}

function cl(x){            //改變顏色
 box.style.background = x;
}

function apply(){
 document.getElementById('set').style.display = 'none';
}

function reset(){            //恢復(fù)DIV原來(lái)的布局
 box.style.width = 100 + 'px';
 box.style.height = 100 + 'px';
 box.style.background = 'white';
}
