另外如果要兼容ie ,firefox netscapt三個瀏覽器，就不能用onkeypress事件。
而應該把onkeypress事件變成 onkeydown事件+onkeyup事件。
再keydown事件中檢查，并設置標志位，在onkeyup事件中返回，類似這樣
script language="javascript">
var tag;
function kd(evt) {
alert(evt.keyCode);
if (evt.keyCode >= 48 && evt.keyCode <= 57) {
tag=true;
return;
}else{
if (evt.keyCode==8){
tag=true;
return;
}
}
tag=false;
}
function kp(){
return tag;
}
</script>
至于為什么這樣，自己測試一下不這樣的結果吧
<script>function formatNumber(number,pattern){ var str = number.toString(); var strInt; var strFloat; var formatInt; var formatFloat; if(/\./g.test(pattern)){ formatInt = pattern.split('.')[0]; formatFloat = pattern.split('.')[1]; }else{ formatInt = pattern; formatFloat = null; } if(/\./g.test(str)){ if(formatFloat!=null){ var tempFloat = Math.round(parseFloat('0.'+str.split('.')[1])*Math.pow(10,formatFloat.length))/Math.pow(10,formatFloat.length); strInt = (Math.floor(number)+Math.floor(tempFloat)).toString(); strFloat = /\./g.test(tempFloat.toString())?tempFloat.toString().split('.')[1]:'0'; }else{ strInt = Math.round(number).toString(); strFloat = '0'; } }else{ strInt = str; strFloat = '0'; } if(formatInt!=null){ var outputInt = ''; var zero = formatInt.match(/0*$/)[0].length; var comma = null; if(/,/g.test(formatInt)){ comma = formatInt.match(/,[^,]*/)[0].length-1; } var newReg = new RegExp('(\\d{'+comma+'})','g'); if(strInt.length<zero){ outputInt = new Array(zero+1).join('0')+strInt; outputInt = outputInt.substr(outputInt.length-zero,zero) }else{ outputInt = strInt; } var outputInt = outputInt.substr(0,outputInt.length%comma)+outputInt.substring(outputInt.length%comma).replace(newReg,(comma!=null?',':'')+'$1') outputInt = outputInt.replace(/^,/,''); strInt = outputInt; } if(formatFloat!=null){ var outputFloat = ''; var zero = formatFloat.match(/^0*/)[0].length; if(strFloat.length<zero){ outputFloat = strFloat+new Array(zero+1).join('0'); //outputFloat = outputFloat.substring(0,formatFloat.length); var outputFloat1 = outputFloat.substring(0,zero); var outputFloat2 = outputFloat.substring(zero,formatFloat.length); outputFloat = outputFloat1+outputFloat2.replace(/0*$/,''); }else{ outputFloat = strFloat.substring(0,formatFloat.length); } strFloat = outputFloat; }else{ if(pattern!='' || (pattern=='' && strFloat=='0')){ strFloat = ''; } } return strInt+(strFloat==''?'':'.'+strFloat);}alert(formatNumber(0,''));alert(formatNumber(12432.21,'#,###'));alert(formatNumber(12432.21,'#,###.000#'));alert(formatNumber(12432,'#,###.00'));alert(formatNumber('12432.415','#,###.0#'));</script>

實現限制輸入大、小寫英文，數字，浮點小數，日期，中文，部分英文，部分中文等眾多功能。直接加入到html代碼中即可使用。

oSel.setEndPoint("StartToStart", srcRange)
var str = oSel.text + inputStr + srcRange.text.substr(oSel.text.length)
return reg.test(str)

2.不能展開右鍵，不能全選，不能復制的實現
<body oncontextmenu="window.event.returnvalue=false"
onkeypress="window.event.returnvalue=false"
onkeydown="window.event.returnvalue=false"
onkeyup="window.event.returnvalue=false"
ondragstart="window.event.returnvalue=false"
onselectstart="event.returnvalue=false">
...
</body>
3.禁止頁面正文內容被選取
<body oncontextmenu="return false" ondragstart="return false"
onselectstart ="return false" onselect="document．selection.empty()"
oncopy="document．selection.empty()" onbeforecopy="return false"onmouseup="document．selection.empty()">
4.避免別人把網頁放在框架中
<script language=“javascript”><!--if (self!=top){top.location=self.location;}-->< /script>
5.禁示查看源代碼
<frameset>
<frame src="你要保密的文件的URL">
</frameset>
6.關閉輸入法
<input style="ime-mode:disabled">
7.禁止圖片下載
在這里的最后加入：
oncontextmenu="return false" ondragstart="return false" onselectstart="return
false" scroll="auto"
8.禁止緩存
在HEAD里加入：
<meta http-equiv="Expires" CONTENT="0">
<meta http-equiv="Cache-Control" CONTENT="no-cache">
<meta http-equiv="Pragma" CONTENT="no-cache">
private functions:通過 var functionName=function(){}聲明
privileged methods: 通過this.methodName=function(){}聲明
privileged properties:通過 this.variableName來聲明
(有些地方把privileged properties叫做public properties，但我感覺無論是按照
定義寫法，還是為了便于理解都叫privileged properties更好些。更便于對比對稱記憶)
prototype methods :通過Classname.prototype.methodname=function(){}來聲明
(有些地方叫public method，同樣和上邊一樣的理由，這里改叫prototype method)
prototype properties:通過 classname.prototype.propertyName=somevalue來聲明
static properties: 通過classname.propertyName=somevalue定義
static method :通過classnamne.methodName來聲明
說明：有些地方（例如我看的文檔中）把privileged properties和prototype method叫成
public properties 和public method，不知道為什么這樣叫。這樣命名后造成的問題是
1,privileged method沒有對應的privileged properties
2,prototype properties沒有對應的prototype method
3,public method和public properties的定義方式又不對稱
下邊解釋一下幾種情況：
1,private：定義在類內部，只能被類內部的方法調用，例如privileged(見實例一中的(1)(2))
2,priviledged ：定義在類內部，能被任何調用，在調用上有點類似Java中
的非靜態public方法(見實例一中的(3))
3,prototype：這個概念不太好理解，在執行上有點像java的clone，只在類初始化的時候
執行一次。每次建立實例的時候不執行。能被繼承。
4,static： 有點類似java中的靜態。各實例共享，不能被繼承
實例一如下：
<script>
function Pet(name,color){
//priviledged properties this.name=name; this.color=color; //private properties var type="animal"; //private method
var run2 = function(){ run(type);
} var run = function(mType){ alert(color+" "+name+" is runing("+mType+")"); } //priviledged method this.callRun = function(){ /**//*(1)priviledged method can visit private properties and private method*/ run(type); }
} Pet.prototype.callPrivateRun =function(pet){ /**//*(2)can not call run*/ //pet.run2(); /**//*(3)can call priviledge method and priviledge properties*/ pet.callRun(); } function test(){ var pet = new Pet("pig","black"); pet.callRun(); alert("prototype"); pet.callPrivateRun(pet); } window.onload=test; </script>實例二演示了繼承、覆寫
另外javascript不支持多態性
<script> function Pet(){ //name this.name=null; this.getName = function() {return this.name;}; this.setName = function(newName) {this.name = newName;}; //abstract method this.eat = null; } /**//*cat inherit from Pet*/ Cat.prototype = new Pet(); function Cat(){ //implement the abstract method this.eat = function(food){ alert("The cat (" + this.name+ ") is eating " + food); } } /**//*dog inherit from Pet*/ function Dog(){ //implements the abstract method this.eat = function(food){ alert("The dog (" + this.name+ ") is eating " + food); } } Dog.prototype = new Pet(); /**//*Hound inherit from dog*/ Hound.prototype = new Dog() function Hound(){ //override this.eat = function(food){ alert("The Hound (" + this.name+ ") is eating " + food); } } function test(){ var cat = new Cat(); cat.setName("mimi"); cat.eat("fish"); var dog = new Dog(); dog.setName("wangwang"); dog.eat("bone"); var hound = new Hound(); hound.setName("hali"); hound.eat("rabbit"); } window.onload=test; </script>function alertInOne(){ alert('in one');}//注意這個地方document.write("<script language='javascript' src='one.js'></script>");function alertInTwo(){ alert("in Two");}<script language='javascript' src="two.js"></script><script language="javascript"> alertInOne(); alertInTwo();</script>應用場合：
在平時開發的時候，我們都會有一些js文件的積累，大部份場合是不需要重新寫的。
但我們會把js文件的功能盡可能的細分，以便引入的時候不引入無用的代碼，但這樣造成的問題是在jsp文件
中要寫大量的這樣的句子
<script language='javascript' src="two.js" charset="utf-8"></script>
如果你有100個jsp文件，都用到10個js文件，這個時候每個jsp文件寫10句引入，這個是個麻煩的事情
現在，通過js文件的引入可以解決這個問題。定義一個js文件用來引入一些組合，jsp文件則只需要引入1個
這樣的js文件就可以了。js代碼少了100*99行
另外引入的js文件時候最好加上charset,特別是你的js文件有非英文，數字的時候。
事例的代碼下載：http://www.aygfsteel.com/Files/dreamstone/importJs.rar
alert(parseInt("8"));
alert(parseInt("08"));
會看到什么結果 ？
首先是8,然后是0,為什么parseInt("08")會是0呢 ？
原因如下：
js在默認情況下是用的10進制，但是如果以0開頭的數字，默認就會變成8進制
所以才會出現8,9錯誤的情況。
解決方案：
解決方法如下 parseInt("08",10);
指定為10進制。
