Combobox

Selected text

Q: How can I get a dropdownlist/combobox selected text in jQuery? .
A: There are several possibilities which can be found on the Internet:

1. The most simple solution (and working solution), but imho very difficult to remember.

   $("#yourdropdownid option:selected").text();

2. A more optimized way, but not working for me.

   $("#yourdropdownid option").is("selected").text()

3. One stated this is the fastest. But imho not working anymore!

   $("#yourdropdownid").children("option").is("selected").text()

4. One stated is() should not be used because it is a boolean whether selected or not. Same problem does not work anymore.

   $("#yourdropdownid").children("option").filter(":selected").text()

So this leaves me to the conclusion the best way to get the values from a combobox are:

• To get the selected key-value of the combo box:

  $("#yourdropdownid option:selected").val();

• To get the selected text-value of the combo box:

  $("#yourdropdownid option:selected").text();

List box

A list box seems to be somewhat more complicated. For me the following construction works fine:

var cList = $("input[name=yourlistname]");
key = cList.filter(":checked").val();
text = cList.filter(":checked").text();
