Question

I’m trying to clone input fields with JS and increment their id and name so I can validate them. Here’s an example:

<input type="text" id="work_company0" name="work[0][company]" />
<input type="text" id="work_company1" name="work[1][company]" />

<input type="text" id="work_title0" name="work[0][title]" />
<input type="text" id="work_title1" name="work[1][title]" />

So for the id, the regex would be:

/^(.*)(\d)+$/i

For id="work_company1", the match results in ["work_company1", "work_company", "1"] and I create the new ID by using match[1] + newID (work_company2).

What would be the regex for the name to get a similar match?

Answer 1

Do you mean this?

var s = 'work[1][title]';
var r = /\w+\[(\d+)\]\[(\w+)\]/;
var m = s.match(r);

// in m variable m[1] is id and m[2] is name

hope this makes sense.
