我ng-pattern="/0-9/"用来设置price_field不接受decimal number.但是当我输入自然数(从0到9999999)时,ng-show会被激活Not valid number!.

我哪里做错了？.请帮忙.

<form name="myform" data-ng-submit="create()">
        <input type="number"
               name="price_field"
               data-ng-model="price"
               require
               ng-pattern="/0-9/"
        <span  ng-show="myform.price_field.$error.pattern">Not valid number!</span>
        <input type="submit" class="btn">
</form>
