<selectid="mySelect"><optionvalue="1">one</option><optionvalue="2"selected="selected">two</option><optionvalue="3">three</option></select><inputtype="text"value="ooo"name="param2"id="param2"/><scriptsrc="jquery.min.js"></script><script>
$('#mySelect').change(function(){
alert($(this).children('option:selected').val());
var p1=$(this).children('option:selected').val();//这就是selected的值 var p2=$('#param2').val();//获取本页面其他标签的值
window.location.href="xx.php?param1="+p1+"m2="+p2+"";//页面跳转并传参
})
</script>
jquery获取select选择的文本与值
获取select 选中的 text :
$("#ddlregtype").find("option:selected").text();
运用newOption("文本","值")方法添加选项option :
var obj = document.getElementById("mySelect");
obj.add(newOption("4","4"));
删除所有选项option:
var obj = document.getElementById("mySelect");
obj.options.length = 0;
删除选中选项option:
var obj = document.getElementById("mySelect");
var index = obj.selectedIndex;
obj.options.remove(index);
修改选中选项option
var obj = document.getElementById("mySelect");
var index = obj.selectedIndex;
obj.options[index] = new Option("three",3); //更改对应的值
obj.options[index].selected = true; //保持选中状态
删除select:
var obj = document.getElementById("mySelect");
obj.parentNode.removeChild(obj); //移除当前对象
