Join an array by a comma and a space
提问by Myles Gray
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:
我有一个要转换为逗号分隔字符串的数组。Array.toString()有效，但如果我有一个相当大的数组，它不会换行，因为逗号后没有空格：
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#,javaHow can I have spaces after the commas in order to allow line/word wrapping?
如何在逗号后有空格以允许换行/自动换行？
Example output:
示例输出：
css, html, xhtml, html5, css3, javascript, jquery, lesscss, arrays, wordpress, facebook, fbml, table, .htaccess, php, c, .net, c#, java

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:
在 JavaScript 中有一个.join()数组方法可以获取字符串，您可以为其提供分隔符。在你的情况下，它看起来像这样：
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(', ');

Use array.join(", ");and it should work
使用array.join(", ");它应该可以工作
回答by John xyz
string.Join(", ", new string[] { "css", "html", "xhtml", ..etc });
This prints the items with a comma and a space
这将打印带有逗号和空格的项目
[edit] I'm sorry, did not see it was for javascript. My code is c# :)
[编辑] 对不起，没有看到它是针对 javascript 的。我的代码是 c# :)
