javascript中的数组 [英] Array in javascript
问题描述
嗨。
是否有可能在javascript中操作阵列而不知道它有多少mamy
元素？
我想要做的是将一个数组发送到一个脚本，这个脚本应该
添加该数组中的所有值
你能告诉我一点吗例子怎么做？
谢谢。

Hi.
Is it possible in javascript to operate on an array without knowing how mamy
elements it has?
What i want to do is sending an array to a script, and this script should
add all values from that array
Could you show me a little example how to do this?
Thanks.

当然。这就是例如Array对象的`length''属性用于。

Of course. This is what the e.g. `length'' property of Array objects is for.

取决于你的意思是将数组发送到脚本 （哪个数组，
哪个脚本，客户端或服务器端，从何处发送？）和
脚本应该添加该数组的所有值 ; （从哪里加到
哪个？）

Depends on what you mean by "sending an array to a script" (which array,
which script, client-side or server-side, send from where to where?) and by
"script should add all values from that array" (add from where exactly to
which?)

JavaScript数组是Dynamic Sparse Jagged Array。这可能是一段时间的形容词太多了b / b：但是第一个意味着可以在没有ReDim / resize（）的情况下向数组中添加新的元数据。
var myArray = new Array（）; // 0元素
myArray [0] = 0;
....
....
myArray [1000] = 1000;

JavaScript array is Dynamic Sparse Jagged Array. That can be too much
of adjectives for one time :-) but the first one means that can add new
elements to array without ReDim / resize() it.
var myArray = new Array(); // 0 elements
myArray[0] = 0;
....
....
myArray[1000] = 1000;
About other adjectives (and about JavaScript arrays at whole) you can

正如所指出的那样取决于如何以及以何种形式你是获得数组的原始数据吗？
As it was pointed out it depends on how and in what form are you
getting the original data for your array.

我不认为，没有''map'这样的功能'或''申请''。然而，他们
并不难实现，因为你总是知道一个
数组的大小：array.length;
