在这种情况下如何使用javascript拆分功能

Question

I have a Name Value pair returned from Javascript array which will be in this format

var priceData = [[0,100.34],[1,108.31],[2,109.40],[3,104.87],[4,106.00]]

I need the last element in that array , so i used this way

var result = priceData[priceData.length-1];

alert(result);

But i am getting result as 4,106.00

I want to get only the 106.00 (That is the last elemenet)

Please tell me , how to do this ??

Answer 1

> x=[[1,2],[3,4],[5,6]]

> x.slice(-1)[0]
[5,6]

> x.slice(-1)[0].slice(-1)[0]
6

alternatively:

> x.slice(-1)[0][1]
6

Answer 2

这是另一个数组，因此索引第1个元素：

var result = priceData[priceData.length-1][1];

Answer 3

The last element of your array is indeed [4, 106.00]. The last element of the last element of your array is 106.00

Answer 4

var priceData = [[0,100.34],[1,108.31],[2,109.40],[3,104.87],[4,106.00]]
var result = priceData[priceData.length-1];
alert(result[result.length-1]);
