Question

尝试使用flask-sijax上传示例上传文件然后提交，但是由于呈现了upload.html，因此提交按钮不断被删除。解决这个问题的最佳方法是什么？

当前，需要单击两次“上传”按钮才能运行，然后代码将生成“提交”按钮，但是当单击“提交”按钮时，它将呈现upload.html，从而导致删除了“提交”按钮

        obj_response.html_append('#formTwoResponse', '<br />Finished!')
@flask_sijax.route(app, "/", methods=['GET','POST'])
def index():
    form_init_js = ''
    if request.method =='POST':
        if request.form.get('one') == 'Upload':
            print("upload")
            form_init_js += g.sijax.register_upload_callback('formOne', SijaxHandler.form_one_handler)
        elif request.form.get('two') == 'submit':
            print("submit")
            form_init_js += g.sijax.register_upload_callback('formTwo', SijaxHandler.form_two_handler)
    if g.sijax.is_sijax_request:
        # The request looks like a valid Sijax request
        # The handlers are already registered above.. we can process the request
        return g.sijax.process_request()
    return render_template('upload.html', form_init_js=form_init_js)

if __name__ == '__main__':
    app.run(debug=True, port=8080)

一键尝试使“上传”按钮起作用，而使提交按钮停留在页面上。
