.ajax({ 网址:' http://172.16.0.110:80/vam/api/Asset/GetAllAssets'， 数据:' {"logInInfo":{"UserName":"eisg"，"Password":"M00s3h3ad"}， "lastAssetIDInternal":"，"lastSyncDate":"，"startSyncDate":"}'， 类型:' POST'， dataType:' json'， contentType:' application/json'， 失败:功能(数据){ alert(" ); alert(" ); } }); }); </script>

这看起来像是跨域Ajax调用.那是做不到的.
如果包含javascript的html文件也托管在您的主机上，则只能执行此操作；

This looks like a cross domain ajax call. That can''t be done.
You can only do this if your html file which contains the javascript is also hosted on;
