請你修改這段代碼。如果未填寫完畢提示“请填写完整表单信息！”如果填寫ok提交彈出對話框提交成功@app.route('/submit', methods=['POST']) def submit(): # 获取表单数据 line = request.form['line'] date = request.form['date'] model = request.form['model'] lists = request.form['lists'] number = request.form['number'] prod_date = request.form['prod_date'] shift = request.form['shift'] prod_line = request.form['prod_line'] responsible = request.form['responsible'] # 表单验证：检查是否所有表单字段都已填写 if not all([line, date, model, lists, number, prod_date, shift, prod_line, responsible]): return "<script>alert('请填写完整表单信息！');history.back();</script>"

好的，根据你的要求，我修改了代码，添加了弹出对话框和表单验证的逻辑。以下是修改后的代码：

@app.route('/submit', methods=['POST'])
def submit():
    # 获取表单数据
    line = request.form['line']
    date = request.form['date']
    model = request.form['model']
    lists = request.form['lists']
    number = request.form['number']
    prod_date = request.form['prod_date']
    shift = request.form['shift']
    prod_line = request.form['prod_line']
    responsible = request.form['responsible']

    # 表单验证：检查是否所有表单字段都已填写
    if not all([line, date, model, lists, number, prod_date, shift, prod_line, responsible]):
        return "<script>alert('请填写完整表单信息！');history.back();</script>"
    else:
        # 在这里添加提交表单信息的代码
        return "<script>alert('提交成功！');window.location.href='/';</script>"

这段代码中，我们先获取表单数据，然后使用 `all` 函数来检查是否所有表单字段都已填写。如果有字段为空，则弹出提示框，并使用 `history.back()` 来返回上一页。如果所有字段都已填写，则我们可以在这里添加提交表单信息的代码，并弹出提交成功的对话框，使用 `window.location.href` 来跳转到首页。

希望这个代码片段能够满足你的需求！
