flaskPython按钮

为两个按钮指定相同的名称和不同的值：

<input type="submit" name="submit_button" value="Do Something"><input type="submit" name="submit_button" value="Do Something Else">

然后，在Flask视图函数中，您可以知道使用了哪个按钮来提交表单：

def contact():    if request.method == 'POST':        if request.form['submit_button'] == 'Do Something': pass # do something        elif request.form['submit_button'] == 'Do Something Else': pass # do something else        else: pass # unknown    elif request.method == 'GET':        return render_template('contact.html', form=form)
