仅允许输入控件中的某些字符

Question

我正在使用jquery不显眼的验证，我的输入看起来像。所以我的输入可以有

<input class="FormElement form-control input-validation-error" data-val="true" data-val-required="The ID field is required." 
id="ID" name="ID" value="6" data-val-regex-pattern="^\d{1,12}(\.\d{0,3})?$|^\.\d{1,3}$" data-val-regex="You are allowed up to 12 digits in front of the decimal and 3 behind." aria-required="true" aria-invalid="true" aria-describedby="ID-error">

有效样本：

12
12.44

无效的样本

12.3333333333333
12.
123456789045555.9
asdsadsadas
12.sw

问题是如何禁止用户在验证之前尝试输入除数字和句点（。）之外的值。

输入元素有一个type属性需要设置为＆＃34; number＆＃34;像这样：

＆＃13;

＆＃13;

<input type="number" class="FormElement form-control input-validation-error" data-val="true" data-val-required="The ID field is required." 
id="ID" name="ID" value="6" data-val-regex-pattern="^\d{1,12}(\.\d{0,3})?$|^\.\d{1,3}$" data-val-regex="You are allowed up to 12 digits in front of the decimal and 3 behind." aria-required="true" aria-invalid="true" aria-describedby="ID-error">

＆＃13;
