I have a question about javascript and jquery. 我对javascript和jquery有疑问。

I have a scenario like this: 我有这样的情况：

I have to download a file by sending a POST request to the server. 我必须通过向服务器发送POST请求来下载文件。 I did this using an invisible form which added to the HTML using jquery. 我使用不可见的表单来完成此操作，该表单使用jquery添加到了HTML中。
My page of download has an implicit refresh build in by legacy code and I cannot change that. 我的下载页面有一个由旧代码生成的隐式刷新，我无法更改它。
The problem is that when I try to add the invisible form to the page, the refresh happens and takes my form away. 问题是，当我尝试将不可见的表单添加到页面时，刷新会发生并且将我的表单删除。

I am thinking whether I can open a new tab, add my download invisible form, send the request and close the tab using some smart javascript. 我在考虑是否可以使用一些智能JavaScript打开一个新标签页，添加我的下载不可见表格，发送请求并关闭该标签页。 I am very new to this area, please help. 我是这个领域的新手，请帮忙。

Add a [target] attribute to your <form> and it will make the request in a new page rather than over the existing page that contains the <form> . 在您的<form>添加[target]属性，它将在新页面而不是在包含<form>的现有页面上发出请求。

[target="_blank"] would probably work, but if this ends up causing too many pages to be created, you could use a named page so that only one download page is created ( [target="downloadpage"] ). [target="_blank"]可能会起作用，但是如果最终导致创建太多页面，则可以使用命名页面，以便仅创建一个下载页面（ [target="downloadpage"] ）。

Alternatively you could try generating your POST request via the XmlHttpRequest object. 或者，您可以尝试通过XmlHttpRequest对象生成POST请求。
