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.
我使用以下内容限制用户只输入一些字符。当我按Tab键时，光标不指向下一个控件（在Mozilla中）。但它在IE中运行良好。
// Restricts user to enter characters other than a to z, A to Z and white space( )

$("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;
}
});
