7.25. Bootstrap5 prompt box

7.25.1. How to create a prompt box ¶

By adding to elements


      data-bs-toggle="tooltip"

let’s create a prompt box.


      title

property is what is displayed in the prompt box:

<button type="button" class="btn btn-primary" data-bs-toggle="tooltip" title="I am the prompt content!">Move the mouse over to me</button>

Note: the prompt box should be written in the initialization code of JavaScript: then call on the specified element


      tooltip()

method.

The following examples can use prompt boxes anywhere in the document:

Example ¶

var tooltipTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]'))
var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) {
  return new bootstrap.Tooltip(tooltipTriggerEl)
})

7.25.2. Specify the location of the prompt box ¶

By default, the prompt box is displayed above the element.

You can use the ‘data bs placement’ attribute to set the direction of the prompt box display:

top


      bottom


      left


      right

Example ¶

<a href="#" data-bs-toggle="tooltip" data-bs-placement="top" title="I am the prompt content!">Move the mouse over to me</a>
<a href="#" data-bs-toggle="tooltip" data-bs-placement="bottom" title="I am the prompt content!">Move the mouse over to me</a>
<a href="#" data-bs-toggle="tooltip" data-bs-placement="left" title="I am the prompt content!">Move the mouse over to me</a>
<a href="#" data-bs-toggle="tooltip" data-bs-placement="right" title="I am the prompt content!">Move the mouse over to me</a>

In recent years, Geographic Information Systems (GIS) have undergone rapid development in both theoretical and practical dimensions. GIS has been widely applied for modeling and decision-making support across various fields such as urban management, regional planning, and environmental remediation, establishing geographic information as a vital component of the information era. The introduction of the “Digital Earth” concept has further accelerated the advancement of GIS, which serves as its technical foundation. Concurrently, scholars have been dedicated to theoretical research in areas like spatial cognition, spatial data uncertainty, and the formalization of spatial relationships. This reflects the dual nature of GIS as both an applied technology and an academic discipline, with the two aspects forming a mutually reinforcing cycle of progress.
