How do I check if any checkboxes at all on the page are checked?

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!

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.

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

or

var isChecked = $('input:checkbox').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
    }

}

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;
}

This works:

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

so

if (ischecked > 0)

then at least one is 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");

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

This should find any checkboxes on the page that are checked
