Question

我使用uiwebview在我的iOS应用程序中执行远程过程。这些远程过程可以对本地http服务器执行某些ajax请求，而本地http服务器将返回执行正确的响应处理程序。这工作正常，直到我尝试再次运行整个脚本，这导致“xmlhttprequest异常101”

处理程序ajax：

NSString* makeHTMLwithRegisteredHandlers(NSString* serverurl)
{
NSMutableString* output = [NSMutableString new];
if(registeredHandlers != nil)
{
    for(int i=0;i<registeredHandlers.count;i++)
    {
        NSString* scriptfunc = [AbstractRemoteProcedure makeGetJSFromClass:[registeredHandlers objectAtIndex:i]];
        [output appendFormat:@"\nfunction %@(paramdata) { \n",scriptfunc];
        [output appendString:@"\t$.ajax({  \n"];
        [output appendString:@"\t\ttype: \"POST\",  \n"];
        [output appendFormat:@"\t\turl: \"%@/%@\",  \n",serverurl,scriptfunc];
        [output appendString:@"\t\tasync:false,  \n"];
        [output appendString:@"\t\tprocessData: false, \n"];
        [output appendString:@"\t\tdata: paramdata, \n"];
        [output appendString:@"\t\terror: function(xhr, ajaxOptions, thrownError) { \n"];
        [output appendString:@"\t\t\talert(\"runtime exception:\"+thrownError);\n"];
        [output appendString:@"\t\t\tbreakmyJS();\n"];
        [output appendString:@"\t\t},\n"];
        [output appendString:@"\t\tsuccess: function(data) { \n"];
        [output appendString:@"\t\t\tresult = data;  \n"];
        [output appendString:@"\t\t}\n"];
        [output appendString:@"\t});\n"];



        [output appendString:@"\treturn result;\n} \n"];


    }
}
return output;
}

serverside脚本：

function onConnect()
{
    //device just connected to network
}

function onRetrieve()
{

var req = new Object();
req.url = servertoRequestFrom;
req.usr = deviceIdentifier();
req.pwd = deviceSecret();
var res = HttpCrossDomainSend(jQuery.stringify(req));
var decoded = jQuery.parseJSON(res);
makeSheet(decoded);


}

function onSend()
{
}

function onAuthorize(action)
{
return false;
}
