我有一个在Android应用程序中使用的html页面 . 从这个页面我需要将数据发布到服务器,响应是需要下载的附件 . 我为此目的使用了隐藏的iframe hack . 但不幸的是它失败了 . 任何人都可以解释根本原因吗?
function download(){
var iframe = document.createElement("iframe");
//iframe.src = "http://localhost:9080/HttpOptions/MultiPartServlet";
iframe.style.display = "none";
iframe.id = "myframe";
document.body.appendChild(iframe);
var doc = document.getElementById("myframe").contentWindow.document;
var form = doc.createElement("form");
form.setAttribute("name", "theForm"); // give form a name
form.setAttribute("id", "theForm"); // give form a name
form.setAttribute("action", "http://localhost:9080/HttpOptions/MultiPartServlet"); // give form an action
form.setAttribute("method", "post"); // give form a method
var par1 = doc.createElement("input");
par1.setAttribute("name", "theSubmit"); // give input a name
par1.setAttribute("type", "submit"); // make it a submit button
par1.setAttribute("value", "Submit"); // give input a value
var par2 = doc.createElement("input");
par2.setAttribute("name", "name"); // give input a name
par2.setAttribute("type", "text"); // make it a submit button
par2.setAttribute("value", "deepak"); // give input a value
form.appendChild(par1);
form.appendChild(par2);
doc.body.appendChild(form);
var myframe = document.getElementById('myframe');
var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
form.submit();
}

在父页面和框架页面中将
document.domain
设置为相同的值 .例:
把它放在父页面和框架页面中,问题就会消失 .
