Transform Javascript Array into delimited String
提问by Alex
I have a Javascript string array with values like A12, B50, C105 etc. and I want to turn it into a pipe delimited string like this: A12|B50|C105...
我有一个带有 A12、B50、C105 等值的 Javascript 字符串数组，我想把它变成一个像这样的管道分隔字符串：A12|B50|C105...
How could I do this? I'm using jQuery (in case that helps with some kind of builtin function).
我怎么能这样做？我正在使用 jQuery（以防它对某种内置函数有帮助）。

var pipe_delimited_string = string_array.join("|");
Array.joinis a native Arraymethod in Javascript which turns an array into a string, joinedby the specified separator (which could be an empty string, one character, or multiple characters).
Array.join是一个本地Array的Javascript方法果然阵列成一个字符串，加入由指定分离器（它可以是一个空字符串，一个字符或多个字符）。

不需要jQuery。使用Javascriptsjoin()方法。喜欢
var arr = ["A12", "C105", "B50"],
str = arr.join('|');
alert(str);

Use JavaScript 'join' method. Like this:
使用 JavaScript ' join' 方法。像这样：
Array1.join('|')Hope this helps.
希望这可以帮助。

For a native JavaScript array then myArray.join('|')will do just fine.
对于原生 JavaScript 数组myArray.join('|')，就可以了。
On the other hand, if you are using jQuery and the return value is a jQuery wrapped array then you could do something like the following (untested):
另一方面，如果您使用的是 jQuery 并且返回值是一个 jQuery 包装的数组，那么您可以执行以下操作（未经测试）：
jQuerySelectedArray.get().join('|')

我使用[email protected]。数组和对象非常好
_.join(['a', 'b', 'c'], '~');
// => 'a~b~c'
