jQuery UI Dialog closeOnEscape用法及代码示例

closeOnEscape选项(如果设置为true且当前对话框处于焦点状态)将在按Escape键(esc)时关闭对话框。默认情况下，值是true。

用法:

$( ".selector" ).dialog({
    closeOnEscape:true
});

方法：首先，添加项目所需的jQuery UI脚本。

<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>

<!doctype html> 
<html lang="en"> 
  
<head>
