python字符串转二维数组_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 = ;

var tree = "[";

for (var i = 0 ;i < typeNO ; i++){

tree += "[";

tree +="'"+ objarr[i][0]+"',";

tree +="'"+ objarr[i][1]+"'";

tree += "]";

if(i

tree+=",";

}

}

tree+="]";

return tree;

}

alert(getString(b));

//结果："[['1','2'],['a','b']] "
