但是,使用 jsfiddle http://jsfiddle.net/LcgnQ/2/我尝试了以下 html 和 javascript 片段:

<input type="button" id="testbutton" value="Test">
</form>
$('#testbutton').bind('click',function(){

Try:
尝试:
$('#profileform')[0].checkValidity()
When you select $('#profileform')
you get a jQuery object array. To access actual DOM properties you must select the first item in the array, which is the raw DOM element.
当您选择时,$('#profileform')
您将获得一个 jQuery 对象数组。要访问实际的 DOM 属性,您必须选择数组中的第一项,即原始 DOM 元素。
