You can't just do document.url.submit(), it doesn't work like that.
你不能只做 document.url.submit()，它不是那样工作的。
Try this:
尝试这个：
<form id="myForm" action="ht.php" method="post">
<input type="hidden" name="someName" value="helloworld" />
<a href="#" onclick="document.getElementById('myForm').submit();">Submit</a>
</form>
That should work!
那应该工作！

Using jQuery, its rather easy:
使用 jQuery，它相当简单：
$('form .submit-link').on({
click: function (event) {
event.preventDefault();
$(this).closest('form').submit();
}
});
Then you just code as normal, assigning the class submit-linkto the form submission links:
然后您只需像往常一样编码，将类分配给submit-link表单提交链接：
<form action="script.php" method="post">
<input type="text" name="textField" />
<input type="hidden" name="hiddenField" value="foo" />
<a href="#" class="submit-link">Submit</a>
</form>
I find this method useful, if you want to maintain an aesthetic theme across the site using links rather than traditional buttons, since there's no inline scripting.
我发现这种方法很有用，如果您想使用链接而不是传统按钮在整个网站上维护美学主题，因为没有内联脚本。
Here's a JSFiddle, although it doesn't submit anywhere.

You could add a hidden field on the page (set it's name property), set it's value to helloworld.
您可以在页面上添加一个隐藏字段（设置其名称属性），将其值设置为 helloworld。
Then in your hyperlink's onclick call form.submit()
然后在你的超链接的 onclick 调用 form.submit()
