javascript - 更改类型为“时间”的输入字段的值(Changing the value of an input field of type:“time”)

Question

This is about a system where users can enter their company open and closing times.(这是关于用户可以输入公司营业时间和营业时间的系统。)

I have 7 fields which are equal to 7 days <input type="time"> , these are populated with times from a database.(我有7个字段，它们等于7天<input type="time"> ，这些字段中填充了来自数据库的时间。) This input has a default display of --:-- but when you change it to that the value of the field is not adjusted.(此输入的默认显示为-：-，但将其更改为该字段的值不会被调整。) What I want is the following: Whenever a user submits the form and a field display consists of --:-- , I want to change the value of that field to -1 .(我想要的是以下内容：每当用户提交表单并且字段显示由-：-组成时，我都希望将该字段的值更改为-1 。) Why?(为什么？) Because -1 means that a company is closed on that day.(因为-1表示该公司在那一天关闭。) How can I achieve this?(我该如何实现？) Example:(例：)   ask by thomas translate from so

Answer 1

The explanation of the problem is not very clear but if you want to display a value from database you can disable the input field and display a value in it with the value=(问题的解释不是很清楚，但是如果您要显示数据库中的值，则可以禁用输入字段，并使用value=在其中显示value=)

Here an example:(这里是一个例子：) <form> <input type="time" name="time" value="09:30" disabled><br> </form>
