mycars['page1'][0] = new Array( "5.00", "5 items", "red" );
mycars['page1'][1]= new Array( "6.00", "6 items", "ed" );
mycars['page1'][2]= new Array( "7.00", "7 items", "d"

推荐答案

不，您不能通过字符串访问数组，那将是一本字典，我不认为js具有.但是2D数组很好.

No, you can''t have an array accessed by strings, that would be a dictionary, which I don''t think js has. A 2D array, however, is fine.

您可以按以下方式操作....

you can do it in the following way....

var mycars = new Array();
            mycars[0] = ["5.00", "5 items", "red"];
            mycars[1] = ["6.00", "6 items", "ed"];
            alert(mycars[0][2]);

使用两个循环，您可以遍历2d数组并找到满足您条件的元素.

using two loops you can go througth the 2d array and find the element that meets your condition.

var xlength = mycars.length;
var ylength = mycars[0].length;

您可以使用上面的代码使用两个维度的长度....

you can use the length of both dimensions using above code....
