how do you unselect all items from a listbox using jquery

is there a way to unselect al开发者_运维知识库l items of a listbox using jquery without looping through each item?

---

The shortest way is this method:

$("#myListBox").val([]);

This sets the value to an empty array, meaning select no values. .val() takes an array in the case of a <select multiple> element. Note that $("select").val('');​​​​​​​ also works here :)

jQuery is designed to work with multiple elements at the same time:

$(listboxSelector).find("option").attr("selected", false);

---

$('#myListbox option').attr('selected',false);

---

$("#mylistbox").options.attr("selected", false);
