closeOnEscape option if set to true and the current dialog box is focused will close the dialog on pressing Escape key(esc). By default, value is true.
Syntax:
$( ".selector" ).dialog({
closeOnEscape : true
});
Approach: First, add jQuery UI scripts needed for your project.
<link href = “https://code.jquery.com/ui/1.10.4/themes/ui-lightness/jquery-ui.css” rel = “stylesheet”>
<script src = “https://code.jquery.com/jquery-1.10.2.js”></script>
<script src = “https://code.jquery.com/ui/1.10.4/jquery-ui.js”></script>
Example 1:
HTML
<!doctype html>
< html lang = "en" >
< head >
< meta charset = "utf-8" >
< link href =
rel = "stylesheet" >
< script src =
</ script >
< script >
$(function () {
$("#gfg").dialog({
closeOnEscape: true,
});
$("#geeks").click(function () {
$("#gfg").dialog("open");
});
});
</ script >
</ head >
< body >
< div id = "gfg" title = "GeeksforGeeks" >
Jquery UI| closeOnEscape dialog option
</ div >
< button id = "geeks" >Open Dialog</ button >
</ body >
</ html >
|
Output:
