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]

In the spirit of teaching a man to fish... Have a look at regular-expressions.info/reference.html, you're probably looking for \d and +. — ohaal

Just try with:

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

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

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

You could;

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

This should do it:

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

I'm pretty sure the category text can be anything. I'm not down voting, just noting.

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.

Yet another approach...

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

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

"category~[330526|330519]^Size{1}~[m]".replace(/(category~[\d+\|\d+]).*/,"$1"), you should get the string, or you can use match as well.
