Description

The Prompt modal allows the users to take some actions on the displayed content. It uses the following methods −

myApp.prompt(text, [title, callbackOk, callbackCancel])

Or

myApp.prompt(text, [callbackOk, callbackCancel])

The above methods accept parameters that are listed below −

  • text − It displays the prompt modal with the text.

  • title − It is an optional method that displays the prompt modal with the title.

  • callbackOk − It is an optional method, which provides the callback function that executes when the "OK" button is clicked by the user on prompt modal.

  • callbackCancel − It is an optional method, which provides the callback function that executes when the "Cancel" button is clicked by the user on prompt modal.

Output

Let us carry out the following steps to see how the above given code works −

  • Save the above given HTML code as modal_prompt.html file in your server root folder.

  • Open this HTML file as http://localhost/modal_prompt.html and the output is displayed as shown below.

  • When the user clicks on the first option, it links to a popup window. When the user enters text into the box, it executes the callback function when OK is clicked.

  • When the user clicks on the second option, it links to a popup window, where it excutes the callback function when the user clicks on the Cancel button. It executes a callback function when the user enters the text into the box and clicks OK.

  • When the user clicks on the third option, it links to a popup window with the text and the title. When the user enters text into the box, it executes the callback function when OK is clicked.

  • When the user clicks on the last option, it links to a popup window with the text and the title and executes a callback function when the user clicks on cancel. It executes a callback function when the user enters the text and clicks OK.
