JQuery ile SELECT elementine neler yapabiliriz


// Add options to the end of a select
$("#myselect").append("");
$("#myselect").append("");

// Add options to the start of a select
$("#myselect").prepend("");

// Replace all the options with new options
$("#myselect").html("");

// Replace items at a certain index
$("#myselect option:eq(1)").replaceWith("");
$("#myselect option:eq(2)").replaceWith("");

// Set the element at index 2 to be selected
$("#myselect option:eq(2)").attr("selected", "selected");

// Set the selected element by text
$("#myselect").val("Some oranges").attr("selected", "selected");

// Set the selected element by value
$("#myselect").val("2");

// Remove an item at a particular index
$("#myselect option:eq(0)").remove();

// Remove first item
$("#myselect option:first").remove();

// Remove last item
$("#myselect option:last").remove();

// Get the text of the selected item
alert($("#myselect option:selected").text());

// Get the value of the selected item
alert($("#myselect option:selected").val());

// Get the index of the selected item
alert($("#myselect option").index($("#myselect option:selected")));

// Alternative way to get the selected item
alert($("#myselect option:selected").prevAll().size());

// Insert an item in after a particular position
$("#myselect option:eq(0)").after("");

// Insert an item in before a particular position
$("#myselect option:eq(3)").before("");

// Getting values when item is selected
$("#myselect").change(function() {
alert($(this).val());
alert($(this).children("option:selected").text());
});
