Show Loading gif on button click

I wanted to show a loading gif on a user button click, because the action would take a while. So this is the solution I found.

You make the div style.display = "none;" then on button click, you set the style.display = "";

HTML input checkbox

The html input tag 'checkbox' will beck checked no matter what value it is set to the attribute 'checked'.  For instance,

checked='' ... or ... checked='checked' ... or ... checked='true' ... or ... checked='false'

will all set the checkbox to checked.

The 'checked=[value]' needs to be totally removed from the attribute list if a non-checked checkbox is desired.

ASP.NET MVC HTML helpers attributes

In order to set attributes for html elements using

"Html.ActionLink(, , , )"

The attributes should be like

new { @attribute=value, ...})

an example of this would be:

new { @id=doneID, @class="invisible"})

The "doneID" is a string variable that was defined earlier in the ' ' of the page.

The @class value is just a string.
