JS又上完了,还是感觉JS技巧性很强,需要多积累经验...看了一下PHP的内容,感觉搭建环境好麻烦,结果回来下了个wamp感觉好像就可以了.....
1.红绿蓝颜色条:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>网页背景颜色控制2</title>
<script type="text/javascript">
window.onload = function(){
//找对象
var inputsObj = document.getElementsByTagName("input");
//加时间
for(var i=0;i<inputsObj.length;i++){
inputsObj[i].onchange = function(){
//找对象
var red = document.getElementById("red").value;
var green = document.getElementById("green").value;
var blue = document.getElementById("blue").value;
//输出颜色
document.body.style.backgroundColor="rgb("+red+","+green+","+blue+")";
//找到span标记并写入内容
var spanObj = document.getElementsByTagName("span");
for(var j=0;j<spanObj.length;j++){
spanObj[j].innerHTML = inputsObj[j].value;
}
}
}
}
</script>
</head>
<body>
红：<input type="range" min="0" max="255" id="red" value="255"><span id="res_red">255</span><br>
绿：<input type="range" min="0" max="255" id="green" value="255"><span id="res_green">255</span><br>
蓝：<input type="range" min="0" max="255" id="blue" value="255"><span id="res_blue">255</span><br>
</body>
</html>
2.选项卡切换
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>选项卡切换</title>
<style type="text/css">
body,ul,li{margin: 0px;padding: 0px;}
ul li{list-style: none;}
.box{
width:298px;
height: 98px;
margin: 10px;
border: 1px solid #eee;
overflow: hidden;
}
.title{
height: 27px;
position: relative;
}
.title ul{
position:absolute;
width: 301px;
left:-1px;
}
.title ul li{
height: 26px;
line-height: 26px;
float: left;
width: 58px;
text-align: center;
overflow: hidden;
background: #fff;
border-bottom: 1px solid #eee;
padding:0px 1px;
background: #f7f7f7;
}
.title ul li.select{
background: #fff;
border-bottom-color: #fff;
border-left: 1px solid #eee;
border-right: 1px solid #eee;
padding:0px;
font-weight: bold;
}
.content .cont{margin: 10px 10px 10px 20px;}
.content .cont ul li{
float: left;
width: 133px;
height: 25px;
line-height: 25px;
overflow: hidden;
}
a:link,a:visited{text-decoration: none;color: #000;}
a:hover{color:#f90;}
</style>
<script type="text/javascript">
window.onload = function(){
var div_titleObj = document.getElementById("title");
var lisObj = div_titleObj.getElementsByTagName("li");

var divsObj = div_contentObj.getElementsByTagName("div");
for(var i=0; i<lisObj.length; i++){
lisObj[i].id = i;
lisObj[i].onclick = function(){
for(var j=0; j<divsObj.length; j++){
divsObj[j].style.display = "none";
