推荐答案

例如，您可以在下拉值更改事件和设置元素href属性时使用jQuery函数来实现此目的.

For example You can achieve this with jQuery function on dropdown value change event and setting element href attribute.

如果需要，可以将<select />更改为@Html.DropDownListFor()或@Html.DropDownList()

If You want, change <select /> to @Html.DropDownListFor() or @Html.DropDownList()

<script type="text/javascript">
    $(document).ready(function () {
        $('.myClass').change(function () {
            $('.mbtn').attr('href', '/MyController/CityInfo?cityid=' + $(this).val());
        });
    })
</script>

<select class="myClass">
    <option value="1">Texas</option>
    <option value="2">Sao Paulo</option>
    <option value="3">Mexico</option>
</select>

@Html.ActionLink("More Info", "CityInfo", null, new { @class = "mbtn" })

更多参数您可以为每个下拉列表class='myClass'和不同的ID.有了它，您应该可以将其用作:

For more parameters You can for every dropdown set class='myClass' and different id. With it You should be able to use it as:

<script type="text/javascript">
    $(document).ready(function () {
        $('.myClass').change(function() {
            $('.mbtn').attr('href', '/MyController/CityInfo?cityid=' + $('#cityId').val() + '&userId=' + $('#userId').val());
        });
    })
</script>
