How to get count with a selection like $(".... :checked")?

I need to get a count of checkboxes that are cu开发者_高级运维rrently checked.

How do I do that?

$(".... :checked").count() doesn't work.

---

$("input:checked").length;

---

Try this

$("input:checked").length

---

$(':checkbox:checked').length should give you the required count.

---

Try this instead:

$(":checked").length

---

Try .length; for example: $('#some_id input:checked').length.

---

try .length or .size() - they are essentially the same thing. Each results in the count of the number of elements in the matched set. Apparently .length is the preferred choice, as it is faster.

---

You need to use length.

$("#something:checked").length;

---

You can always assign a class to the check box elements and select them using the following syntax:

$('input[class="yourCheckBoxClass"]:checked').length;

This will give you the total of check boxes selected.
