需要关联数组帮助。 [英] Associative array help needed.

问题描述

我正在使用关联数组来模拟多维数组，例如

这个：


myArray [''00''] =" John" ;;

myArray [''01''] =" 35";

myArray [' '02''] =" 12345";

myArray [''03''] =" 01/01 / 1975" ;;


myArray [''10''] =" Sarah";

myArray [''11''] =" 29";

myArray [''12'' ] =" 56789";

myArray [''13''] =" 12/12/19" ;;


我正在尝试弄清楚如何循环整个数组，我有一些问题。


for（var i = 0; i< arrayCount ; i ++）

{

for（var j = 0; j< attribCount; j ++）

{

提醒（myArray [i + j]）;

}

}


现在这不行，因为它将i和j加在一起加入他们的是b $ b加入他们。当我做'我'和'''时，它不起作用，所以我想知道，是否实际可以循环通过阵列？

？


感谢您的帮助。

我正在使用一个关联数组来模拟多维数组，如
这个：

myArray [''00''] =" John" ;;
myArray [''01''] =" 35";
myArray [''02''] =" 12345";
myArray [''03''] =" 01 / 01/1975" ;;

myArray [''10''] =" Sarah" ;;
myArray [''11''] =" 29" ;;
myArray [''12''] =" 56789";
myArray [''13''] =" 12/12/19" ;;

我正在努力工作如何遍历整个数组，我有一些问题。

for（var i = 0; i< arrayCount; i ++）
{
for（var j = 0; j< attribCount; j ++）
{
alert（myArray [i + j]）;
}
}

现在这不起作用，因为它正在添加i和j一起而不是加入他们。当我做'我'和'''时它不起作用所以我很想知道，
它是否真的可以在数组中循环？

感谢您的帮助。

尝试：


for（var i = 0; i< arrayCount; i ++）

{

for（var j = 0; j< attribCount; j ++）

{

alert（myArray） [i * 10 + j]）;

}

}


可能为（var i = 0; i< arrayCount / 10; i ++）


但我不知道arraycount是什么....

尝试：

for（var i = 0; i< arrayCount; i ++）
{
for（var j = 0; j< attribCount; j ++）
{
警报（myArray [i * 10 + j]）;
}
}

for（var i = 0; i< arrayCount / 10; i ++）

但我不知道arraycount是什么....

这真的很聪明，我希望我能想到这一点。

>我正在使用关联数组来模拟像

这样的多维数组：

myArray [''00''] =" John" ;;
myArray [''01''] =" 35";
myArray [''02''] =" 12345";
myArray [''03''] =" 01/01 / 1975" ;;

myArray [''10''] =" Sarah" ;;
myArray [''11''] =" 29" ;;
myArray [ ''12''] =" 56789";
myArray [''13''] =" 12/12/19" ;;

我正在努力解决如何遍历整个数组，我遇到了一些问题。

对于这种数据有一个更好的表示：一个数组对象：


myArray = [{

name：" John"，

age：" 35"，br />
编号：" 12345"，

date：" 01/01 / 1975"}，

{

名称：莎拉，

年龄：29，

号码：56789，

日期：12/12/19} ;;

Hi,

I''m using an associative array to simulate a multidimensional array like
this:

myArray[''00''] = "John";
myArray[''01''] = "35";
myArray[''02''] = "12345";
myArray[''03''] = "01/01/1975";

myArray[''10''] = "Sarah";
myArray[''11''] = "29";
myArray[''12''] = "56789";
myArray[''13''] = "12/12/19";

I''m trying to work out how to loop through the entire array and I''m having
some problems.

for (var i = 0; i < arrayCount; i++)
{
for (var j = 0; j < attribCount; j++)
{
alert(myArray[i + j]);
}
}

Now this doesn''t work as it''s adding the i and j together rather than
joining them. And it doesn''t work when I do ''i'' and ''j'' so I''m wondering, is
it actually possible to loop through the array?

Thanks for any help.

try:

for (var i = 0; i < arrayCount; i++)
{
for (var j = 0; j < attribCount; j++)
{
alert(myArray[i*10 + j]);
}
}

maybe for (var i = 0; i < arrayCount/10; i++)

but I don''t know what arraycount is....

That''s really clever, I wish I''d thought of that.

There is a better representaion for this kind of data: an array of objects:

myArray = [{
name: "John",
age: "35",
number: "12345",
date: "01/01/1975"},
{
name: "Sarah",
age: "29",
number: "56789",
date: "12/12/19"}];
