我使用Unity for IoC,我的注册看起来像这样:
container.RegisterType<IServiceA, ServiceA>();
container.RegisterType<IServiceB, ServiceB>();

当我解析一个ServiceA
实例时,serviceB
将是null

我想在变量中定义扩展名的图像上做一些事情。以下脚本运行良好:
set AllowExt="jpg png bmp"
forfiles /p D:\Pictures /m *.* /c "cmd /c if not %AllowExt:jpg=% == %AllowExt% echo @file

但以下脚本引发错误
set AllowExt="jpg png bmp"
forfiles /p D:\Pictures /m *.* /c "cmd /c if not %AllowExt:@ext=% == %AllowExt% echo @file"

错误:无效的参数/选项 - 'png'。输入“文件/?” 用于使用。
我有以下js片段:
<script language="javascript">
function test() {
this.a = 10;
};
test.prototype.next = function () {
alert('before: ' + this.a);
$.ajax({
url: 'some-url',
async: true,
type: 'POST',
dataType: 'json',
success: this.callback
});
};
test.prototype.callback = function () {
alert('after: ' + this.a);
};
$(document).ready(function () {
var test1 = new test();
test1.next();
});
</script>

它总是产生结果:之前:10之后:undefine.
为什么在$ .post的回调函数中,类的属性是未定义的.谁能帮助我?非常感谢.
