標題圖

歡迎到我的簡書檢視我的文集

前言:

提示密碼提示框

<head>
<style>
#div1 {width: 100px;height:50px;background:#FFCC99;border:1px solid #FF9900; dispaly: none;}
</style>
<title>dashucoding</title>
</head>
<body>
// get Element By Id
<input type="checkbox" onmouseover="" "doucument.getElementById('div1').style.dispaly='block';" onmouseout="document.getElementById('div1').style.display='none'; "/>自動登入
<div id="div1" " >
 達叔小生
</div>
</body>

<label>標籤是用來分組

<label onmouseover="" "doucument.getElementById('div1').style.dispaly='block';" onmouseout="document.getElementById('div1').style.display='none';>登入</label>
<div id="div1">
 不要在網咖上網
</div>

alert使用

元素獲取

// 元素的獲取
id
document.getElementById
// 屬性操作
obj.style.display = "block"
document.getElementById("div1").style.display="block"

<div id="div1" class="box"></div>

<style>
 div{width:100px; height:100px; background:red;}
 .box {width: 200px; height: 200px; background: green;}
</style>

<body>
<div id="div1 onmouseover="document.getElementById('div1').className="box"; " onmouseout="document.getElementById('div1').className="box";">
</div>
</body>

換膚

換css樣式表,調好相容,改變 href 的值

<link id="link1" href="css1.css" rel="stylesheet" type="text/css" >

<input id="btn1" type="button" value="面板1" onclick="document.getElementById('link1').href='css1.css';" />
<input id="btn2" type="button" value="面板2" onclick="document.getElementById('link1').href='css2.css';" />

#idv1 {width:100px; height:100px; background:red;}
<div id="div1" onmouseover="document.getElementById("div1").style.width="200px" ;
onmouseover="document.getElementById("div1").style.height="200px" ;
">

<div id="div1" onmouseover="toRead()" onmouseout="toRes()">
</div>

getElementsByTagName
this
if
for

下拉列表

<div id="box">
<p id="btn">輸入法</p>
<ul id="ul1" style="display:block;">
<li><a href="#">手寫</a></li>
<li><a href="#">拼音</a></li>

var oP=document.getElementById('btn');
var oUl=document.getElementById('ul1');
oP.onclick=function ()
{
if(oUl.style.display=='block')
{
oUl.style.display='none';
}
else//none
{
oUl.style.display='block';
}
};
};
</script>

全選

<p id="btn">全選</p>
<input type="checkbox"/><br/>
<input type="checkbox"/><br/>
<input type="checkbox"/><br/>

var aInput=document.getElementsByTagName("input");
aInput.length
aInput[0].checked=true;

for(i=0; i<5; i++){
 alert('dashucoding');
}

獲取

控制checkbox的狀態為checked
獲取一組元素為getElementsByTagName

for迴圈

重複執行操作
for迴圈的執行順序

<style>
 div{width: 100px; height: 100px; border: 1px solid black; }
</style>
<script type="text/javascript">
window.onload=function(){

全選

var i=0;
oBtn.onclick = function(){
 for(i=0;i<aInput.length;i++){
aInput[i].checked=true;
 }
}

響應按鈕

<script type="text/javascript>
 window.onload=function(){
var aBtn = document.getElementsByTagName('input');
var i = 0;
for(i=0; i<aBtn.length; i++){

</body>

for(i=0;i<aBtn.length;i++){
 aBtn[i].onclick=functiion(){
alert(this.value);
 };
}
