Check multiple checkbox selection using jquery

Question

I am trying to find the easiest way to get the checkboxes that are selected.

Here's my script:

$(document).ready(function() {
    $("input[name='chkTextEffects']").change(function() {
        if ($("#cbSolid").is(':checked') == true) {
            alert('Solid');
        } else if ($("#cbOutline").is(':checked') == true) {
           alert('Outline');
        } else if ($("#cbSolid", "#cbOutline").is(':checked') == true) {
            alert('SolidOutline');
        } else if ($("#cbSolid", "#cbOutline").is(':checked') == false) {
            alert('No Effects'); 
        }
    });
});​

HTML:

   <input type="checkbox" name="chkTextEffects" id="cbSolid" value="Solid" />Solid
   <input type="checkbox" name="chkTextEffects" id="cbOutline" value="Outline" />Outline
   <input id="TextEffectsSelection" type="hidden" />

I'm not sure about this line if ($("#cbSolid", "#cbOutline").is(':checked') == true) or should I use bind to get that worked.

Here is an example I created that demonstrates what I think you're attempting to achieve:

$('#getCheckboxesButton').live('click', function(event) {
    var checkboxValues = [];
    $('input[type="checkbox"]:checked').each(function(index, elem) {
        checkboxValues.push($(elem).val());
    });
    alert(checkboxValues.join(', '));
});

Let me know if that helps. Its basically using the ':checked' jQuery selector to retrieve checkboxes that are checked, then iterating through their values and printing it out.

You can use the :checked selector like this to get all checked checkboxes with the specified name:

$("input[name='chkTextEffects']:checked")
