我有存储阵列的阵列。我需要从这个数组中提取特定的值。

I have an array of array stored. I need to extract the particular value from this arrays.

例如allarray包含数组列表allarray = [阵列[3]，阵列[3]，数组[3]是三阵列present

e.g allarray contain the list of arrays allarray= [Array[3],Array[3],Array[3]] are three arrays present in that.

0：数组[3] 0：A1 1：B1 2：C1

0:Array[3] 0:"a1" 1:"b1" 2:"c1"

1：数组[3] 0：A2 1：B2 2：C2

1:Array[3] 0:"a2" 1:"b2" 2:"c2"

3：数组[3] 0：A3 1：B3 2：C3

3:Array[3] 0:"a3" 1:"b3" 2:"c3"

我需要提取该C1，从上述阵列和显示在警报框c2和c3

I need to extract this c1,c2 and c3 from the above arrays and display in the alert box.

谁能告诉我，我该怎么办呢？

Can anyone tell me how i can do that?

我试着用$。每个可惜不工作。任何人都可以？

i tried with $.each but unfortunately doesn't work. Can anyone?

推荐答案

如果我理解正确，你的阵列看起来像这样

If I understand you correctly, your array looks like this

var allarray = [["a1","b1","c1"],["a2","b2","c2"],["a3","b3","c3"]];

要获得C1，C2和C3你可能只是做到这一点。

To get c1, c2, and c3 you could just do this

var c1 = allarray[0][2], c2 = allarray[1][2], c3 = allarray[2][2];

或你可以做一个循环来把所有的CS在自己的单个阵列

or you could do a loop to put all of the cs in a single array of its own

var cs = []; for(var i = 0; i < allarray.length; i++) { cs.push(allarray[i][2]); }
