在 <Enter> 上提交 jQuery UI 对话框 [英] Submit jQuery UI dialog on &lt;Enter&gt;

问题描述

我有一个带有表单的 jQuery UI 对话框.我想模拟对对话框按钮之一的单击，这样您就不必使用鼠标或标签.换句话说，我希望它像一个普通的 GUI 对话框一样模拟点击确定"按钮.

I have a jQuery UI dialog box with a form. I would like to simulate a click on one of the dialog's buttons so you don't have to use the mouse or tab over to it. In other words, I want it to act like a regular GUI dialog box where simulates hitting the "OK" button.

我认为这可能是对话框的一个简单选项，但我在 jQuery UI 中找不到它文档.我可以用 keyup() 绑定每个表单输入，但不知道是否有更简单/更干净的方法.谢谢.

I assume this might be a simple option with the dialog, but I can't find it in the jQuery UI documentation. I could bind each form input with keyup() but didn't know if there was a simpler/cleaner way. Thanks.

推荐答案

我不知道 jQuery UI 小部件 中是否有选项，但您可以简单地将 keypress 事件绑定到包含对话框的 div...

I don't know if there's an option in the jQuery UI widget, but you could simply bind the keypress event to the div that contains your dialog...

$('#DialogTag').keypress(function(e) {
    if (e.keyCode == $.ui.keyCode.ENTER) {
          //Close dialog and/or submit here...
    }
});

无论您的对话框中的哪个元素具有焦点，这都会运行，这取决于您想要什么，这可能是也可能不是一件好事.

This'll run no matter what element has the focus in your dialog, which may or may not be a good thing depending on what you want.

如果你想让它成为默认功能，你可以添加这段代码:

If you want to make this the default functionality, you can add this piece of code:

// jqueryui defaults
$.extend($.ui.dialog.prototype.options, { 
    create: function() {
        var $this = $(this);

        // focus first button and bind enter to it
        $this.parent().find('.ui-dialog-buttonpane button:first').focus();
        $this.keypress(function(e) {
            if( e.keyCode == $.ui.keyCode.ENTER ) {
                $this.parent().find('.ui-dialog-buttonpane button:first').click();
                return false;
            }
        });
    } 
});

以下是其外观的更详细视图:

Here's a more detailed view of what it would look like:

$( "#dialog-form" ).dialog({
  buttons: { … },
  open: function() {
    $("#dialog-form").keypress(function(e) {
      if (e.keyCode == $.ui.keyCode.ENTER) {
        $(this).parent().find("button:eq(0)").trigger("click");
      }
    });
  };
});
