js综合代码段

1、屏蔽右键

<SCRIPT language=javascript> 　　 function Click(){ 　　 window.event.returnValue=false; 　　 } 　　 document.oncontextmenu=Click; 　　 </SCRIPT>  

 

2、设计为首页，添加收藏

 

<a href="#" mce_href="#" onClick="this.style.behavior='url(#default#homepage)';this.setHomePage('http://www.yaowomei.com');">设为首页</a> <a href="javascript:window.external.AddFavorite('http://www.yaowomei.com','要我美')" mce_href="javascript:window.external.AddFavorite('http://www.yaowomei.com','要我美')">收藏我们</a>

3、打印本页

<input id="btnPrint" type="button" value="打印" onclick="javascript:window.print();" />

打印区域 ：
 <script>
 function printarea(oper) {
if (oper < 10){
bdhtml=window.document.body.innerHTML;//获取当前页的html代码
sprnstr="<!--startprint-->";//设置打印开始区域
eprnstr="<!--endprint-->";//设置打印结束区域
prnhtml=bdhtml.substring(bdhtml.indexOf(sprnstr)+18); //从开始代码向后取html

prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));//从结束代码向前取html
window.document.body.innerHTML=prnhtml;
window.print();
window.document.body.innerHTML=bdhtml;

} else{
window.print();
}

} 
 </script>

4、复制链接

function copyToClipboard() 
	{ 
	var ch=document.location; 
	ch +='\r\n'; 
	<!--var ch=a.value;-->
	window.clipboardData.setData("Text",ch); 
	alert("已复制链接"); 
	} 

5、判断浏览器、

function getExplorer() {
var explorer = window.navigator.userAgent ;
//ie 
if (explorer.indexOf("MSIE") >= 0) {
alert("ie");
}
//firefox 
else if (explorer.indexOf("Firefox") >= 0) {
alert("Firefox");
}
//Chrome
else if(explorer.indexOf("Chrome") >= 0){
alert("Chrome");
}
//Opera
else if(explorer.indexOf("Opera") >= 0){
alert("Opera");
}
//Safari
else if(explorer.indexOf("Safari") >= 0){
alert("Safari");
}
}

6.即时时间

<input id="thedatebj" type="text" style="font-size: 9pt; border: 0; width: 75px; background:none; color:#FFF; " readonly="readonly" /> <input  id="thetimebj" type="text" style="font-size: 9pt; border: 0; width: 30px; background:none; color:#FFF;" readonly="readonly" />
<script language="javascript" type="text/javascript">

var timerID = null;
var timerRunning = false;
function stopclock (){
	if(timerRunning)clearTimeout(timerID);
	timerRunning = false;
}
stopclock();
showtime();

function showtime(){
	var now = new Date();
	var hours = now.getHours();
	var minutes = now.getMinutes();		
	var timeValue =hours; 	
	timeValue += ((minutes < 10) ? ":0" : ":") + minutes;	
	document.getElementById("thetimebj").value=timeValue;
	timerID = setTimeout("showtime()",1000);
	timerRunning = true;	
}

today=new Date();
function initArray(){
	this.length=initArray.arguments.length;
	for(var i=0;i<this.length;i++)this[i+1]=initArray.arguments[i];
}
document.getElementById("thedatebj").value=today.getFullYear()+"-"+(today.getMonth()+1)+"-"+today.getDate();
</script>
