javascript - 使用 Bootstrap Dropdown 和 Jquery 更改 Bootstrap 表单

标签 javascript jquery html twitter-bootstrap user-interface

我想使用下拉菜单和 jquery 更改要显示的表单，但似乎不起作用。我确实尝试了一个简单的代码，只使用了几个 div 和一个段落，它起作用了，或者我认为是这样，因为当我把我的表单放进去时它不再起作用了。 顺便说一句，这是我的代码:

//this is the form

<div class="container">
    <h3>Choose the brand you want to input</h3> <br>
    <select id="brand-combox" class="custom-select col-sm-2" name="brand-combox">
        <option selected value="#">Select a Brand</option>
        <option value="qnap">Qnap</option>
        <option value="asustor">Asustor</option>
        <option value="nutanix">Nutanix</option>
        <option value="dji">DJI</option>
        <option value="wps">WPS Office</option>
    </select>
</div>

这是 jquery:

$('#brand-combox').on('change', function(){
                if (this.value == 'qnap') {
                    $('#qnap-form').show();
                    $('#asustor-form').hide();
                }
                else if(this.value == 'asustor'{
                    $('#qnap-form').hide();
                    $('#asustor-form').show();
                }
            });

我也尝试过任何不同的方法，但我还不能找出我遗漏了什么。 你愿意帮助我吗？

最佳答案

你的 else if 条件不符合 ) 并添加 jquery，检查它 

$('#brand-combox').on('change', function(){
                if (this.value == 'qnap') {
                    $('#qnap-form').show();
                    $('#asustor-form').hide();
                }
                else if(this.value == 'asustor'){
                    $('#qnap-form').hide();
                    $('#asustor-form').show();
                }
            });
