Javascript接受16个字符(所有数字),不少于或不多
<div class="col-xs-4">
<div style="text-align:left;" class="form-group">
<label for="credit0_number">Credit Card Number</label>
<input type="number" class="inp form-control" id="credit0_number" name="credit0[number]" >
</div>
</div>
我试过maxlength = '16'但是它也没用min="16" max = "16",我也做了,它也没有用,我该怎么办？
