I need to check, using jQuery, if any checkboxes on the page are checked. The particular checkbox set they are contained in doesn't matter, just any of them.

Any ideas?

Thanks!

var isChecked = $("input[type=checkbox]").is(":checked");

or

var isChecked = $('input:checkbox').is(':checked')

The following function returns true if there are any ticked checkboxes and false otherwise.

function anyCheckbox()
{
    var inputElements = document.getElementsByTagName("input");
    for (var i = 0; i < inputElements.length; i++)
        if (inputElements[i].type == "checkbox")
            if (inputElements[i].checked)
                return true;
    return false;
}

if($('checkbox:checked').length > 0)
    //Some checkbox is checked

This should find any checkboxes on the page that are checked

if you only want to look at checkboxes, not radio buttons: var isChecked = $("input:checkbox").is(":checked");

if you're ok with checkboxes or radio buttons: var isChecked = $("input").is(":checked");

This works:

var ischecked =$('input[type=checkbox]:checked').length;

so

if (ischecked > 0)

then at least one is checked.

function checkbox(){
    var ischecked =$('input[type=checkbox]:checked').length;
    if (ischecked <= 0){        // you can change your condition
    alert("No Record Selected");
    return false;
    }else
    {
      -------//your Action that you want
    }

}

Here is the modern JS way, without using jQuery:

Array.from(document.querySelectorAll('[type=checkbox]')).some(x => x.checked)

It will return true if at least one checkbox is checked, false otherwise.
