js綜合程式碼片段

1、屏蔽右鍵

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

 

2、設計為首頁，添加收藏

 

<a href="#" mce_href="#" onClick="this.style.behavior='url(#default#homepage)';this.setHomePage('http://www.yaowomei.com');">設為首頁</a></p><p> <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')">收藏我們</a>

3、列印本頁

<input id="btnPrint" type="button" value="列印" onclick="javascript:window.print();" />列印範圍 ： <script> function printarea(oper) {if (oper < 10){bdhtml=window.document.body.innerHTML;//擷取當前頁的html代碼sprnstr="<!--startprint-->";//設定列印開始地區eprnstr="<!--endprint-->";//設定列印結束地區prnhtml=bdhtml.substring(bdhtml.indexOf(sprnstr)+18); //從開始代碼向後取htmlprnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));//從結束代碼向前取htmlwindow.document.body.innerHTML=prnhtml;window.print();window.document.body.innerHTML=bdhtml;} else{window.print();}}  </script>

4、複製連結

function copyToClipboard() { var ch=document.location; ch +='\r\n'; <!--var ch=a.value;-->window.clipboardData.setData("Text",ch); alert("已複製連結"); } 

5、判斷瀏覽器、

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.即時時間

<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>
