在Firefox中使用JavaScript捕获标签键 [英] Capturing the tab key using JavaScript in Firefox

问题描述

我使用以下内容限制用户只输入一些字符。
当我按Tab时，光标不指向下一个控件（在Mozilla中）。但它在IE中正常工作。

I use the following to restricts user to enter only some characters. When I press tab, the cursor does not point to next control (in Mozilla). But it works fine in IE.

// Restricts user to enter characters other than a to z, A to Z and white space( )
// Rauf K. 06.11.2010
$("input:text.characters_only").keypress(function(e) {
if (!((e.which >= 65 && e.which <= 90) || (e.which >= 97 && e.which <= 122) || e.which == 32 || e.which == 8 || e.which == 9)) {
        return false;
    }
});

推荐答案

我建议尝试 e .keyCode 而不是 e.which 。这是一个SO链接，它描述了一个很好的方法，可以将键击到单个变量： jQuery事件键：按下哪个键？

I would recommend trying e.keyCode instead of e.which. Here is a SO link that describes a good method of getting the key strike into a single variable regardless: jQuery Event Keypress: Which key was pressed?
