jQuery获取Select选择的Text和Value:
语法解释:
$("#select_id").change(function(){ var checkText=$("#select_id").find("option:selected").text(); var checkValue=$("#select_id").val(); var checkIndex=$("#select_id ").get(0).selectedIndex; var maxIndex=$("#select_id option:last").attr("index");
语法解释:
$("#select_id ").get(0).selectedIndex=1; $("#select_id ").val(4); $("#select_id option[text='jQuery']").attr("selected", true); -
jQuery添加/删除Select的Option项:
语法解释:
-
$("#select_id").append("<option value='Value'>Text</option>"); -
$("#select_id").prepend("<option value='0'>请选择</option>"); -
$("#select_id option:last").remove(); -
$("#select_id option[index='0']").remove(); -
$("#select_id option[value='3']").remove(); -
$("#select_id option[text='4']").remove();
我的疑惑:
我设置Select的选中项:用“$("#select_id option[text='jQuery']").attr("selected", true);
