我自己调用表单的submit时候,不和本身网页的行为一样,查了查资料说,submit 不会调用onsubmit handler, 自己fireevent可以做到是吧?但是 The IHTMLFormElement::submit method does not invoke the onsubmit event handler. Call the onsubmit event handler directly. When using Microsoft Internet Explorer 5.5 and later, you can call the IHTMLDocument4::fireEvent method with a value of onsubmit in the sEvent parameter. MSDN上最后一句话,看不懂
