问题描述

我试图在用户按下文本框中的 Enter 键时将焦点设置为按钮.但这是行不通的.我正在使用Internet Explorer 8浏览器.我想念什么吗?

I am trying to set the focus to a button while the user presses the Enter key in the text box. But it is not working. I am using the Internet Explorer 8 browser. Am I missing something?

$("input.Box").live('keydown', function(e) {
    if (e.keyCode == 13) {
        e.preventDefault(); 
        $("#button").focus(); // Not working?
    }
});

推荐答案

Microsoft决定他们不喜欢e.keyCode，而是使用自己的语法e.which.

Microsoft decided that they don't like e.keyCode and instead have their own syntax, e.which.

您必须同时检查两者:

$("input.Box").live('keydown', function(e) {
    var keyCode = (window.event) ? e.which : e.keyCode;

    if (keyCode == 13)
        e.preventDefault(); 
        $("#button").focus(); // Not working?
    }
});
