我在使用IE9顯示我的Haxe遊戲時遇到問題。它實際上根本不顯示。我們在編譯後的JS文件中追蹤了Haxe的問題，發現問題出在haxe.HTTP API中。Haxe IE9 xmlHTTPrequest問題
有些東西需要檢查和完成IE9與xmlhttprequests一起使用。這些事情並沒有在Haxe API中完成。
這是沒有我的固定的HTTP類：
this.url = url;
this.headers = new List();
this.params = new List();
this.async = true;
};
$hxClasses["haxe.Http"] = haxe.Http;
haxe.Http.__name__ = ["haxe","Http"];
haxe.Http.prototype = {
setParameter: function(param,value) {
this.params = Lambda.filter(this.params,function(p) {
return p.param != param;
});
this.params.push({ param : param, value : value});
return this;
}
,request: function(post) {
var me = this;
me.responseData = null;
var r = this.req = js.Browser.createXMLHttpRequest();
var onreadystatechange = function(_) {
if(r.readyState != 4) return;
var s;
try {
s = r.status;
} catch(e) {
s = null;
}
if(s == undefined) s = null;
if(s != null) me.onStatus(s);
if(s != null && s >= 200 && s < 400) {
me.req = null;
me.onData(me.responseData = r.responseText);
} else if(s == null) {
me.req = null;
me.onError("Failed to connect or resolve host");
} else switch(s) {
case 12029:
me.req = null;
me.onError("Failed to connect to host");
break;
case 12007:
me.req = null;
me.onError("Unknown host");
break;
default:
me.req = null;
me.responseData = r.responseText;
me.onError("Http Error #" + r.status);
}
};
if(this.async) r.onreadystatechange = onreadystatechange;
var uri = this.postData;
if(uri != null) post = true; else {
var $it0 = this.params.iterator();
while($it0.hasNext()) {
var p = $it0.next();
if(uri == null) uri = ""; else uri += "&";
uri += encodeURIComponent(p.param) + "=" + encodeURIComponent(p.value);
}
}
try {
if(post) r.open("POST",this.url,this.async); else if(uri != null) {
var question = this.url.split("?").length <= 1;
r.open("GET",this.url + (question?"?":"&") + uri,this.async);
uri = null;
} else r.open("GET",this.url,this.async);
} catch(e1) {
me.req = null;
this.onError(e1.toString());
return;
}
if(!Lambda.exists(this.headers,function(h) {
return h.header == "Content-Type";
}) && post && this.postData == null) r.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
var $it1 = this.headers.iterator();
while($it1.hasNext()) {
var h1 = $it1.next();
r.setRequestHeader(h1.header,h1.value);
}
r.send(uri);
if(!this.async) onreadystatechange(null);
}
,onData: function(data) {
}
,onError: function(msg) {
}
,onStatus: function(status) {
}
,__class__: haxe.Http
};
，這與修復代碼：
haxe.Http = function(url) {
this.url = url;
this.headers = new List();
this.params = new List();
this.async = true;
};
$hxClasses["haxe.Http"] = haxe.Http;
haxe.Http.__name__ = ["haxe","Http"];
haxe.Http.prototype = {
setParameter: function(param,value) {
this.params = Lambda.filter(this.params,function(p) {
return p.param != param;
});
this.params.push({ param : param, value : value});
return this;
}
,request: function(post) {
var me = this;
me.responseData = null;
var r = this.req = js.Browser.createXMLHttpRequest();
var onreadystatechange = function(_) {
console.log('in onreadystatechange function');
//if(r.readyState != 4) return;
console.log(r.responseText);
console.log('r.status: ' + r.status);
me.req = null;
me.onData(me.responseData = r.responseText);
};
if(typeof XDomainRequest != "undefined") {
console.log('XDomainRequest');
r.onload = onreadystatechange;
}
var uri = this.postData;
try {
console.log('calling r.open with url: ' + this.url);
r.open("GET",this.url);
} catch(e1) {
me.req = null;
this.onError(e1.toString());
return;
}
//r.send(uri);
//do it, wrapped in timeout to fix ie9
setTimeout(function() {
r.send();
}, 0);
//if(!this.async) onreadystatechange(null);
}
,onData: function(data) {
}
,onError: function(msg) {
}
,onStatus: function(status) {
}
,__class__: haxe.Http
};
請注意，這只是實現了IE9修正而if語句做保持對其他瀏覽器的支持。但這很簡單。 IF語句僅僅是
if(typeof XDomainRequest != "undefined") return new XDomainRequest();
基本上，我知道是什麼問題，我只是不知道我該怎麼HAXE自身的核心內改變這些東西。
謝謝。
