javascript - 如何使用拆分？(How to use split?)

Question

I need to break apart a string that always looks like this:

(我需要分解一个始终如下所示的字符串：)

something -- something_else.

(东西-something_else。)

I need to put "something_else" in another input field.

(我需要在另一个输入字段中输入“ something_else”。)

Currently, this string example is being added to an HTML table row on the fly like this:

(当前，此字符串示例正被即时添加到HTML表行中，如下所示：)

tRow.append($('<td>').text($('[id$=txtEntry2]').val()));

I figure "split" is the way to go, but there is very little documentation that I can find.

(我认为“拆分”是可行的方法，但是几乎找不到文档。)
