简介：这是在Javascript中如何定义二维数组的详细页面，介绍了和javascript,有关的知识、技巧、经验，和一些javascript源码等。
在Javascript中如何定义二维数组，它的声明都有哪一些简洁的声明方法呢？下面是我收集的一些定义的方法。 
Javascript二维数组定义[一]：

JavaScript代码

    <script>     
      var   a=new   Array();     
      a[1]=new   Array(“a”,”b”);     
      </script>  

——————————————————————————–
Javascript二维数组定义[二]：

JavaScript代码

    <script   language=”JavaScript”>     
      <!–     
      var   a   =   new   Array();     
      a[0]   =   new   Array(“a”,”b”);     
      a[1]   =   new   Array(“c”,”d”);     
      alert(a[1][1]);     
      //–>     
      </script>   

——————————————————————————–
Javascript二维数组定义[三]：?

JavaScript代码

    var   arr   =   new   Array([1,2,3],[4,5,6],[7,8,9,10]);     
      for(var   e   in   arr)   alert(arr[e]);     
       

——————————————————————————–
Javascript二维数组定义[四]：?
先声明一个数组：  
 
JavaScript代码

    var a=new   arrray(first_num);     
      a[first_num]=new   array(number);     
      a[first_num]=new   array(number);     
       
      //first_name是维数，     
      //number可以根据你的需要来了。     
      //这样可以创造出多维数组了。    
    

——————————————————————————–
Javascript二维数组定义[五] ?

JavaScript代码

    <script>     
      T=new   Array;     
      T[1]=new   Array;     
      T[1][0]=”a”;     
      T[1][1]=”b”;     
      alert(T[1][0]);     
      </script>  

——————————————————————————–
Javascript二维数组定义[六]?

JavaScript代码

    <script>     
      var   result   =   new   Array(new   Array(“1″,”1111″),     
            new   Array(“2″,”2222″),   new   Array(“3″,”3333″),     
            new   Array(“4″,”4444″));     
      for(var   i=0;i<   result.length;i++){     
      alert(result[i][0]+”|”+result[i][1]);
