Question

What is the equivalent code in jQuery for the below JavaScript function?

function attachSomeHandler(in) {
    for(var i = 0; i < in.length; i++) {
        if(in[i].type == 'submit') 
            in[i].attachEvent("onclick", someFunc);
    }
}

Answer 1

Assuming the argument in is an array of DOM elements and you already have that array and you want to reproduce the exact same function attachSomeHandler(), you could do this using jQuery:

function attachSomeHandler(in) {
    $(in).filter('[type="submit"]').click(someFunc);
}

If you want to back up to a higher level in your code, you can create a single jQuery selector that would get the original array of DOM elements that was already filtered to only have ones with the appropriate type.
