问题描述
我有一个数组，我想转换为逗号分隔的字符串。 Array.toString（）有效，但是如果我有一个相当大的数组，它将不会换行，因为逗号后面没有空格：
I have an array that I want converted to a comma delimited string. Array.toString() works, but if I have a rather large array it won't wrap because there are no spaces after the commas:
document.body.innerHTML = ['css','html','xhtml','html5','css3','javascript','jquery','lesscss','arrays','wordpress','facebook','fbml','table','.htaccess','php','c','.net','c#','java'].toString();
// css,html,xhtml,html5,css3,javascript,jquery,lesscss,arrays,wordpress,facebook,fbml,table,.htaccess,php,c,.net,c#,java如何在逗号后面加上空格以允许换行/换行？
How can I have spaces after the commas in order to allow line/word wrapping?
示例输出：
css, html, xhtml, html5, css3, javascript, jquery, lesscss, arrays, wordpress, facebook, fbml, table, .htaccess, php, c, .net, c#, java
推荐答案
在JavaScript中有方法开启数组获取字符串，您可以提供分隔符。在你的情况下，它看起来像这样：
In JavaScript there's a .join() method on arrays to get a string, which you can provide the delimiter to. In your case it'd look like this:
var myArray = ['css','html','xhtml','html5','css3','javascript','jquery','lesscss','arrays','wordpress','facebook','fbml','table','.htaccess','php','c','.net','c#','java'];
var myString = myArray.join(', ');
