如何提醒所选选项的值属性

Question

我想提醒选择选项框的"值"属性的值

<select class="form-control" id="selet-city" required >
    <option selected disabled>Please select a City</option>
    <option vlaue="dsfsdfsd">bangalore</option>
    <option>2</option>
    <option>3</option>
    <option>4</option>
    <option>5</option>
    <option>6</option>
    <option>7</option>
</select>

我试过这个：-

alert($('#selet-city option:selected').attr('value'));

Answer 1

alert($("#selet-city option:selected").val())

你可以检查一下

$("#selet-city").change( function(){alert($("#selet-city option:selected").val());})
