使用jQuery获取下拉菜单项的选定值

function fundrp(){ var text_value = $("#drpboxid option:selected").text(); console.log(text_value); var val_text = $("#drpboxid option:selected").val(); console.log(val_text); var value_text = $("#drpboxid option:selected").attr("value") ; console.log(value_text); var get_att_value = $("#drpboxid option:selected").attr("id") console.log(get_att_value); } <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.2.3/jquery.min.js"></script> <select id="drpboxid"> <option id="1_one" value="one">one</option> <option id="2_two" value="two">two</option> <option id="3_three" value="three">three</option> </select> <button id="btndrp" onclick="fundrp()">Tracking Report1234</button>

var value = $('#dropDownId:selected').text()

应该工作得很好，请看这个例子:

$(文档)时函数(){ $ (' # button1 ') .click(函数(){ 警报($ #组合:选择)。text ()); })； })； < script src = " https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js " > < /脚本> <选择id = "组合" > <option value="1">Test 1</option> . </option> . <option value="2">Test 2</option> . </option> . < /选择> <input id="button1" type="button" value="点击!"/>

$("#selector <b>></b> option:selected").val()

Or

$("#selector <b>></b> option:selected").text()

以上代码对我来说工作得很好

还有一个经过测试的例子:

<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>
<script>
$(document).ready(function(){
    $('#bonus').change(function() {
    alert($("#bonus option:selected").text());
  });  
});
</script>
</head>

<body>
<select id="bonus">
<option value="1">-$5000</option>
<option value="2">-$2500</option>
<option value="3">$0</option>
<option value="4">$1</option>
<option value="5">We really appreciate your work</option>
</select>
</body>
</html>

这将提醒所选值。 JQuery代码…

$(document).ready(function () {

        $("#myDropDown").change(function (event) {
            alert("You have Selected  :: "+$(this).val());
        });
    });

HTML代码…

<select id="myDropDown">
        <option>Milk</option>
        <option>Egg</option>
        <option>Bread</option>
        <option>Fruits</option>
    </select>
