JavaScript的 - 转换数组的字符串，而preserving支架 [英] javascript - Convert array to string while preserving brackets

问题描述

我有一个多维数组，看起来像这样：

  VAR myArray的= [1,2,3,4,5]
              [1,2,3,4,5]
              [1,2,3,4,5]
              [1,2,3,4,5]];
 

我希望把它的内容的div（这样就可以轻松地复制和粘贴）。

然而，当我这样做

  VAR X =的document.getElementById（结果）;
x.textContent = myArray的;
 

我只是得到

  1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,1,2,3,4，五
 

解决方案

使用<一个href=\"https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify\"><$c$c>JSON.stringify():

  VAR X =的document.getElementById（结果）;
x.textContent = JSON.stringify（myarray的）;
 

I have a multidimensional array that looks like this:

var myArray =[[1,2,3,4,5], 
              [1,2,3,4,5], 
              [1,2,3,4,5], 
              [1,2,3,4,5]];

I wish to put its contents in a div (so that one can easily copy and paste).

However, when I do

var x = document.getElementById("result");
x.textContent = myArray;

I just get

1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5

解决方案

Use JSON.stringify():

var x = document.getElementById("result");
x.textContent = JSON.stringify( myArray );
