HTML5范围滑块的最小值和最大值

Question

I have an HTML5 slider within an ASP.NET MVC 5 application:

<input type="range" name="rangeInput" min="0.00" max="100" value="0" step="5">

How can I get the max value from an Microsoft SQL Server table?

Do I need to use Jquery/Ajax for this to access a controller action to then get the value from the database?

I have looked on the internet for answers but have had no luck so far.

Answer 1

You already have specified the Max value in the declaration of the slider.

If you mean how you can get the value of the slider from the database then, you need to query from the server side and set the value returned using jquery's val method in the Ajax call of get type.

Answer 2

Usually you don't access the database directly from the View (your HTML page), that is against the principle of the MVC architecture.

Besides the MVC architecture you can use other tiers, and use an ORM like Entity Framework to access the Database.

To learn ASP.Net MVC I would recommend you to read the book from Dino Esposito (Programming Microsoft ASP.NET MVC), get the latest edition.
