methods for toggling between states

Toggling Methods

//general toggling - use another variable
var x = 0;
$('#toggle-btn').click(function(e){
    if( x == 1 ){
        $(this).removeClass('clicked');
        x = 0;
    } else {
        $(this).addClass('clicked');
        x = 1;
    }
    e.preventDefault();
});

//checkboxes only - toggles between each checkbox's state
$('#select').click(function(){
    $('input[type=checkbox]').trigger('click');
});
$("#select").click(function(){
    $("input").each (function() {
        this.checked = !this.checked;
    });
});

//.prop( propertyName, valueToSet) - toggles selectAll and selectNone
$(document).ready(function() {
    $("button").click(function() {
        var checkBoxes = $("input[name=recipients\\[\\]]");
        checkBoxes.prop("checked", !checkBoxes.prop("checked"));
    });                 
});
