Question

Is there a way to call a function when an id matches a regex?

I have an app where I have about 20 or so divs calling the same function by onclick and I’m trying to get rid of the onclicks and just find those divs by id. The divs id’s start the same way for instance: sameId_xxx

This is what I have working but I was wondering if I could put the condition in the function call so it’s not being called for every div on the page.

$("div").click(function () {
    var id = this.id;
    if (id.match(/sameId_/)) {

    }
}

Answer 1

$('div[id^="sameId_"]').click(...)
