二维数组、字符串互相转换

以下是随便写的例子。

1.字符串转二维数组

var a="[["1","2","3","4","5"],["a","b","c","d","e"],["y1","y2","y3","y4","y5"]] ";

var str=eval(a);

alert(str[0][3]);

//结果：4

 

2.二维数组转字符串

var b=[["1","2"],["a","b"]];

function getString( objarr ){
　　var typeNO = objarr.length;
  　 var tree = "[";
 　　for (var i = 0 ;i < typeNO ; i++){
   　　　tree += "[";
   　　　tree +="""+ objarr[i][0]+"",";
   　　　tree +="""+ objarr[i][1]+""";
  　　　 tree += "]";
  　　　 if(i<typeNO-1){
    　　 　　tree+=",";
 　　　  }
  　 }
  　 tree+="]";
  　 return tree;
}

alert(getString(b));

//结果："[["1","2"],["a","b"]] "
