Browsers (Firefox, Chrome...) normally bind the Esckey to the "stop loading current page" action. Any other behaviour needs to be specifically coded with JavaScript.
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用 JavaScript 专门编码。
The jQuery UI Dialog has a closeOnEscapesetting. Just set it to false:
jQuery UI 对话框有一个closeOnEscape设置。只需将其设置为false：
Initialize a dialog with the closeOnEscape option specified:
$( ".selector" ).dialog({ closeOnEscape: false });Get or set the closeOnEscape option, after init:
//getter var closeOnEscape = $( ".selector" ).dialog( "option", "closeOnEscape" ); //setter $( ".selector" ).dialog( "option", "closeOnEscape", false );
使用指定的 closeOnEscape 选项初始化对话框：
$( ".selector" ).dialog({ closeOnEscape: false });在 init 之后获取或设置 closeOnEscape 选项：
//getter var closeOnEscape = $( ".selector" ).dialog( "option", "closeOnEscape" ); //setter $( ".selector" ).dialog( "option", "closeOnEscape", false );

$(document).keydown(function(e) {
if (e.keyCode == 27) return false;
});

The best way to do this is to figure out which dialog library you are using (colorbox? jquery ui? shadowbox) and disable the esckey (for example, in Colorboxyou can set the escKeyoption to false).
最好的方法是找出您使用的是哪个对话框库（colorbox？jquery ui？shadowbox）并禁用该esc键（例如，在Colorbox 中您可以将escKey选项设置为 false）。
