用户输入字段可以更好地使用DIV或仅计算公式的网页表单？ [关闭]

分类: 技术问答 • 2022-03-08 12:15:26
问题描述：

I want to have 6 input fields in a webpage. If the user presses a button the 6 fields expand to 7,8, 9, or 10 fields. The fields are editable and come with a preset value. With the input from the user (or the preset values) a final value is calculated via a formula.

  1. Is it better to use a form for the fields or DIVs?
  2. Should I use JavaScript or something else I am not thinking about yet?
  3. Should I use AJAX when getting the values or is it not needed in this case?
  4. I thought about using an excel like editor made with jQuery https://github.com/mleibman/SlickGrid/wiki/Examples but it seems overkill for my needs plus I would need to edit a lot of it since I want a simple display of the fields.

我想在网页中有6个输入字段。 如果用户按下按钮，则6个字段将扩展为7,8,9或10个字段。 这些字段是可编辑的，并带有预设值。 使用来自用户的输入（或预设值），通过公式计算最终值。 p>

I would use a form as you're asking the users for their data to be input. This will also trigger the keyboard on mobile/tablet devices if you're also targeting those platforms.

Javascript is fine for this, unless you want to hide the formula you're using (as they will be able to see it if they view your source).

Do you need to use AJAX? Are the pre-populated values going to change that much? If not, then no, it's just adding extra work when you could just have an array of values.
