python - 如何在选择下拉列表中从 onchange 调用 url 链接

Question

通常我使用 url '/filterSelectedStatus/' 从 GET 按钮调用

<input type = "submit" value = "  Get  " align="center" onclick="javascript: form.action='/filterSelectedStatus/';"/>

但同样我需要从 django 模板中的 onchange 调用。但是下面的代码不起作用...

<select name = "selStatus" onchange = '/filterSelectedStatus/' method = 'get' >
    {% for list in statusList %}
        <option value = "{{ list}}"> {{ list }} </option>
    {% endfor %}
    <option selected= "{{ selStatus }}">{{ selStatus }} </option>
</select>

谢谢，拉梅什。

onchange 属性用于调用 javascript，如文档所述here .在您的 javascript 中，创建如下函数:

var filterSelectedStatus = function (e) {
    // Log the event e to the console to see what you can do with it
    console.log(e);
    // Do whatever you want here, like JavaScript GET requests
};

然后只需将您的html更改为

<select name = "selStatus" onchange = 'filterSelectedStatus()'>
    {% for list in statusList %}
        <option value = "{{ list}}"> {{ list }} </option>
    {% endfor %}
    <option selected= "{{ selStatus }}">{{ selStatus }} </option>
</select>
