怎么定义数组的数组？ [英] how define array of array?

问题描述

您好，


这可能是我遇到问题的答案 - 或者可能不是

可能吗？！


我可以将变量情况和计数的初始值定义为


var situation = 0;

var count = 0;


在应用程序期间的情况从0到7不等，数从0

到8，


并且有


值[情况] [计数]？


如果是，如何在阵列中定义数组？


谢谢


Geoff

解决方案

在Javascript Arrays中是flat，所以为了制作多个尺寸，你需要创建一个数组作为另一个数组的项目，因此： -


//一个阵列可以是另一个元素的元素ARRAY

var value = new Array（）;

value [0] = new Array（）;

value [0] [0] =" value00";

value [0] [1] =" value01";

value [1] = new Array （）;

value [1] [0] =" value10";

value [1] [1] =" value11";

alert（value [0] [1]）;

// SHORTHAND JSON NOTATION

var value = []; // SAME AS var value = new Array


//等价于上面

var value = [[" value00"，" value01"] ，[" value10"，" value11"]];

alert（value [0] [1]）;

你好，

这可能是我遇到的问题的答案 - 或者可能不是可能的？！


var count = 0;

何时在应用程序情况下将从0到7不等，数从0
到8，

值[情况] [数量]？

如果是，如何定义阵列数组？

谢谢

var value = new Array（8）;

for（var n = 0; n< value.length; n ++）{

value [n] = new Array（9）;

}

Dag，


谢谢你上面 - 它帮助我让应用程序正常运行，但是我已经不是很清楚怎么回事了？！


我使用的实际代码是


for（var n = 0; n< slider_value.length; n ++）{

slider_value [n] = new Array（8）;

}


你会看到我使用的是Array（8）而不是Array（9）。


我正在使用的数组收集一些滑块值，是


slider_value [situation_number] [count]


其中situation_number在0到6之间变化


和


计数在0到7之间变化。


上面的数组或数组的定义是否适合这个？


干杯

Hello,

This may be the answer to a problem I have - or it may not be
possible?!

Can I have initial values of variable situation and count defined as

var situation = 0;
var count = 0;

when during the app situation will vary from 0 to 7 and count from 0
to 8,

and have

value[situation][count] ?

If yes, how do I define the array if arrays?

Thanks

Geoff

解决方案

In Javascript Arrays are "flat", so to make multiple dimensions, you
create an Array as an item of another Array, thus:-

// AN ARRAY CAN BE AN ELEMENT OF ANOTHER ARRAY
var value=new Array();
value[0]=new Array();
value[0][0]="value00";
value[0][1]="value01";
value[1]=new Array();
value[1][0]="value10";
value[1][1]="value11";
alert (value[0][1]);
// SHORTHAND JSON NOTATION
var value=[]; // SAME AS var value=new Array

// EQUIVALENT TO THE ABOVE
var value=[ ["value00","value01"] , ["value10","value11"] ];
alert (value[0][1]);

var value = new Array(8);
for (var n = 0; n < value.length; n++ ) {
value[n] = new Array(9);
}

Dag,

Thanks for above - it has helped me to get the app working but I am
not quite clear how yet?!

The actual code I use is

for (var n = 0; n < slider_value.length; n++ ) {
slider_value[n] = new Array(8);
}

You will see I use Array(8) rather than Array(9).

The array I am using to collect some slider values, is

slider_value[situation_number][count]

where situation_number varies between 0 and 6

and

count varies between 0 and 7.

Does the defination of the array or arrays above fit in with this?

Cheers

Geoff
