问题描述

我想在HTML页面中禁用ESC键。我该怎么做？

I want to disable the ESC key in an HTML page. How can I do this?

我有一个表格显示为jQuery UI Dialog。如果我单击ESC键，表单将关闭。我想禁用它。

I have a form which is appearing as jQuery UI Dialog. Here if I click the ESC key, the form will close. I want to disable that.

推荐答案

浏览器（ Firefox ， Chrome ...）通常将 Esc 键绑定到停止加载当前页面操作。任何其他行为都需要使用JavaScript进行专门编码。

Browsers (Firefox, Chrome...) normally bind the Esc key to the "stop loading current page" action. Any other behaviour needs to be specifically coded with JavaScript.

jQuery UI对话框中有一个 closeOnEscape 设置。只需将其设置为 false ：

The jQuery UI Dialog has a closeOnEscape setting. Just set it to false:

• 使用closeOnEscape初始化对话框指定的选项：

• Initialize a dialog with the closeOnEscape option specified:

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

在init之后获取或设置closeOnEscape选项：

Get or set the closeOnEscape option, after init:

//getter
var closeOnEscape = $( ".selector" ).dialog( "option", "closeOnEscape" );
//setter
$( ".selector" ).dialog( "option", "closeOnEscape", false );
