一直试图让以下代码在 Firefox 插件中工作:
var oMyForm = new FormData();
oMyForm.append("username", "Groucho");
oMyForm.append("accountnum", 123456); // number 123456 is immediately converted to string "123456"
// HTML file input user's choice...
oMyForm.append("userfile", fileInputElement.files[0]);
// JavaScript file-like object...
var oFileBody = '<a id="a"><b id="b">hey!</b></a>'; // the body of the new file...
var oBlob = new Blob([oFileBody], { type: "text/xml"});
oMyForm.append("webmasterfile", oBlob);
var oReq = new XMLHttpRequest();
oReq.open("POST", "http://foo.com/submitform.php");
oReq.send(oMyForm);
所以我知道我必须使用 XPCOM,但我找不到等价物。到目前为止我发现了这个:
var oMyForm = Cc["@mozilla.org/files/formdata;1"].createInstance(Ci.nsIDOMFormData);
oMyForm.append("username", "Groucho");
oMyForm.append("accountnum", 123456); // number 123456 is immediately converted to string "123456"
// JavaScript file-like object...
var oFileBody = '<a id="a"><b id="b">hey!</b></a>'; // the body of the new file...
var oBlob = Cc["@mozilla.org/files/file;1"].createInstance(Ci.nsIDOMFile, [oFileBody], { type: "text/xml"});
oMyForm.append("webmasterfile", oBlob);
var oReq = Cc["@mozilla.org/xmlextras/xmlhttprequest;1"].createInstance(Ci.nsIXMLHttpRequest);
oReq.open("POST", "http://localhost:3000");
oReq.send(oMyForm);
本质上,问题是var oBlob = Cc["@mozilla.org/files/file;1"].createInstance(Ci.nsIDOMFile, [oFileBody], { type: "text/xml"});
因为"@mozilla.org/files/file;1"
或Ci.nsIDOMFile
不正确。请注意,nsIDOMFile 继承自 nsIDOMBlob。
有谁知道该怎么做?
谢谢一堆。
