Introducing interactivity with user input
The interactivity we saw previously with the dynamic data table works within the web browser itself using JavaScript, and it does not need to go through the server function to provide the interactivity, only to pass the table itself. However, many interesting interactivity features need to go through the server so that we can provide custom responses for them. In this section, we show how to add various types of inputs to our application.
Setting up static user inputs
First, we will show how to filter the timestamps in the data to only show observations that fall within a range defined by the user. To do this, we need to first define four timestamps: the minimum, the initial left limit, the initial right limit, and the maximum. These four values will be used by our date range widget to define the allowed range for the user (the minimum and maximum values are used for this), as well as the initial date range (the initial left and right limits are used...
