我已经解决了这个问题超过一周了,而且我所有人都尝试过这样的工作。我从Jquery开始,发现Ie9与其他浏览器不同,并且需要自己的方式来调用wcf。这很简单,我做了所有必需的,但它仍然没有工作! IIS上的这两个地址都是http://localhost。我还重命名了我的html文件,因此它变成了一个aspx文件。我添加了一个Custom ContentTypeMapper,所以我不会与内容类型发生冲突。我不会添加我在这里尝试的所有内容,因为我可以用它来写一本书。你到目前为止我找到了最好的东西。我收到了来自Fiddler的错误消息。这是代码:
使用Javascript:
function CallService() {
var xdr;
function err() {
alert('Error');
}
function timeo() {
alert('Time off');
}
function loadd() {
alert('Response: ' +xdr.responseText);
}
function stopdata() {
xdr.abort();
}
xdr = new XDomainRequest();
if (xdr) {
xdr.onerror = err;
xdr.ontimeout = timeo;
xdr.onload = loadd;
xdr.timeout = 10000;
xdr.open('POST','http://localhost/Path/Service.svc/AjaxEndpoint' + '/FunctionName');
xdr.send()
} else {
alert('XDR undefined');
}
}

编辑: 我查看了httperr1.log和inetpub \ logs \ LogFiles \ W3SVC1中的文件,但是到目前为止,没有人能比Fiddler提供更多的信息。我仍然没有线索。
答案 0 :(得分:0)
显然,问题来自真实源文件的拼写错误(这里没有出现的拼写错误)上面看到的代码有效。我会在这里留下我的问题,因为它似乎是正确的方式继续下去,如果它对你不起作用,就像它对我一样,很可能是因为一个错字。
