looks like msgisn't what you expect. I think you want msg.responseText
看起来msg不是你所期望的。我想你想要msg.responseText
The reason you see [object Object] is because msgis of type object and you pass it into .htmlwhich will convert it to a string. And thus the html is filled with the string representation of object which in this case is "[object Object]"
您看到 [object Object] 的原因是因为它msg是 object 类型，您将其传递给.html它将转换为字符串。因此，html 填充了对象的字符串表示，在这种情况下是“[object Object]”

You will need to pass the value or the text of the #name object. Like this:
您将需要传递 #name 对象的值或文本。像这样：
var name = $("#name").val();
var name = $("#name").text();

msgappears to be a document object, rather than a string containing the appropriate name. It seems to me that you want $('#response').text($(msg).find('h1').text());
msg似乎是一个文档对象，而不是包含适当名称的字符串。在我看来你想要$('#response').text($(msg).find('h1').text());

The good-old IE expects to redirect somewhere when you use an anchor tag. If you have something like the following:
当您使用锚标记时，古老的 IE 期望重定向到某个地方。如果您有类似以下内容：
<a href="javascript: submit()">Submit</a>
IE will show you blank page with [Object object]when using JSON, even if submit()uses ajax.
IE 会[Object object]在使用 JSON 时显示空白页面，即使submit()使用 ajax。
You can use onClick instead or javascript:void sumbit()like this:
您可以改用 onClick 或javascript:void sumbit()像这样：
<a id="btn-submit">Submit</a>
<script>
$(document).on('click', '#btn-submit', function(event){
event.preventDefault();
submit();
});
</script>
I didn't test the void solution but a coworker of mine says that's the one he uses.
我没有测试 void 解决方案，但我的一位同事说这是他使用的解决方案。
