onsubmit()是一个js事件,该事件会在表单提交时触发。想了解更多onsubmit()知识可以看这篇文章。

而submit是一个方法,该方法用于提交form表单。想了解更多submit知识可以看这篇文章。

由此可以看出二者操作的前后顺序,onsubmit()在前,submit在后。

下面是onsubmit()与submit()区别的实例。

<code class="language-html"><script>
function fun()
{
   alert("form_submit");
}
</script>

<form onsubmit="fun()">
<input type="submit" id="aaa" value="submit">   <!--能弹出form_submit-->
<input type="button" id="bbb" value="onCliCk_submit" onclick="doCument.forms[0].submit()">
<!--
表单会提交,但是不会运行fun() 原因是 onsubmit事件不能通过此种方式触发,直接用脚本doCumetn.formName.submit()提交表单是不会触发表单的onsubmit()事件的
-->
    <input type="button" id="bb1" value="onCliCk_onsubmit" onclick="doCument.forms[0].onsubmit()">

<!--会触发fun()参数-->
</form></code>
