使用该代码阻止用户将数字价值输入文字箱:

$( input[type=text] ).keydown(function(event) {
    // Allow only backspace and delete
    if (event.keyCode == 46 || event.keyCode == 8 || event.keyCode == 190) {
        // let it happen, don t do anything
    }
    else {
        // Ensure that it is a number and stop the keypress
        if ((event.keyCode < 48 || event.keyCode > 57) && (event.keyCode < 96 || event.keyCode > 105)) {
            event.preventDefault();
        }
    }
});

然而,这从侧重于下一个文本箱的表格中删除了关键。 如果I 在钥匙down活动上添加这一代码,则表格关键工程,但用户根本无法在文本箱中输入任何价值,而表格钥匙将只侧重于下一个方框。 之后,它不去下个箱子,而把钥匙再次.。

var code = event.keyCode || event.which;
if (code == 9) {
    alert ("Tab key pressed");
}
return false;

if ((event.keyCode < 48 || event.keyCode > 57) && (event.keyCode < 96 || event.keyCode > 105))

该代码包括<代码>9(表格)。 如果您希望能提供<条码> 表格<<>><><>>>/代码>,则须添加<条码>;和

将您的法典与9条放在起职时的位置,并使执行守则在栏目<代码>上正确;
