Match string using regex

Question

I have the following variable:

var test = category~[330526|330519]^Size{1}~[m]

How do I match just to get category~[330526|330519] using regex.

This value can also change so it could be category~[3303226|333219]

Answer 1

只需尝试：

test.split('^')[0];

Answer 2

var test = 'category~[330526|330519]^Size{1}~[m]';

var result = test.split('^').shift();

Answer 3

你可以;

 result = test.substr(0, test.indexOf("]") +1);

Answer 4

应该这样做：

category~\[\d+\|\d+\]

Answer 5

If you insist on using a Regex, this one doesn't care about what the category is (.*~\\[\\d+\\|\\d+\\]) . Here is a Rubular to prove it . But I have to say, the answer by @hsz is really the most insightful. The split is probably the right tool for the job.

Answer 6

Yet another approach...

var test = 'category~[330526|330519]^Size{1}~[m]';

var result = test.replace(/\^.+/,"");

Answer 7

“ category〜[330526 | 330519] ^ Size {1}〜[m]”。replace（/（category〜[\\ d + \\ | \\\\ d +]）。* /，“ $ 1”），应该获取字符串，或者您也可以使用match。
