DHTML實用指南

改進CheckBox：
<label for="check1">單擊我可以改變 CheckBox的狀態</lable>
<input type="checkbox" id="check1" value="often" name="checkoften">

使用Label實現快速鍵的功能：
<table width="400" border="0">
  <tr>
    <td><label for="name" accesskey="N">姓名(<u>N</u>)</label></td>
    <td><input type="text" id="name"></td>
  </tr>
</table>

文字框的提示和輸入
<input type="text" name="name" value="請輸入你的姓名" onfocus=this.select() onmouseover=this.focus()>

開啟和關閉一個新的視窗:
<button onClick="NewWindow=window.open('http://blog.csdn.net/zhoujian2003','這是一個新表單','toolbar=no,statusbar=no,width=200,height=200');">開啟我的Ｂｌｏｇ</button>
<button onClick="NewWindow.close()">關閉我的Ｂｌｏｇ</button>

數組中的方法：
join()是將數群組轉換成字串,括弧裡的欄位是指定的分隔字元．
<script>
array1=new Array("A","B","C");
document.write(array1.join()+"<br>");
document.write(array1.join(" ")+"<br>");
document.write(array1.join(" and "));
</script>

sort()是排序：

array1=new Array("A","B","C","Z","T","M");
document.write(array1.sort());
------對數字進行排序
array2=new Array("12","56","6","20");
function numSort(num1,num2)
{
 return num1-num2;
}
document.write(array2.sort(numSort));

reverse()是排列順序顛倒：
<script>
array1=new Array("A","B","C","Z","T","M");
document.write(array1.join()+"<br>");
document.write(array1.reverse());
</script>

slice()是截取數組：
<script>
array1=new Array("A","B","C","Z","T","M");
document.write(array1.join()+"<br>");
document.write(array1.slice(1,4).join());
</script>

concat()用來串連數組：
<script>
var array1=new Array("A","B","C","Z","T","M");
var array2=new Array("a","b","c","c");
var array3=array1.concat(array2);
document.write(array1.join()+"<br>");
document.write(array2.join()+"<br>");
document.write(array3.join()+"<br>");
</script>

delete 方法用於刪除數組中的元素：
<script>
var array1=new Array("A","B","C","Z","T","M");
document.write(array1.length+"<br>");
document.write(array1.join()+"<br>");
delete array1[3];
document.write(array1.length+"<br>");
document.write(array1.join()+"<br>");
</script>

這是一個對字串的外觀處理的樣本
<script>
document.write("這是一個對字串的外觀處理的樣本");
var strDemo="歡迎大家訪問我的Blog------http://blog.csdn.net/zhoujian2003";
document.write(strDemo.big()+"<br>");
document.write(strDemo.blink()+"<br>");
document.write(strDemo.bold()+"<br>");
document.write(strDemo.fixed()+"<br>");
document.write(strDemo.fontcolor("red")+"<br>");
document.write(strDemo.fontsize(5)+"<br>");
document.write(strDemo.italics()+"<br>");
document.write(strDemo.small()+"<br>");
document.write(strDemo.strike()+"<br>");
document.write(strDemo.sup()+"<br>");
document.write(strDemo.sub()+"<br>");
</script>

字串的link()方法：
<script>
document.write("我的Blog".link("http://blog.csdn.net/zhoujian2003"));
</script>
