我正在尝试找到一种方法来在请求Https资源时忽略证书检查,到目前为止,我在互联网上找到了一些有用的文章.
但我还是有一些问题.请查看我的代码.我只是不明白代码ServicePointManager.ServerCertificateValidationCallback是什么意思.
何时调用此委托方法？还有一个问题,我应该在哪个地方编写这段代码？在ServicePointManager.ServerCertificateValidationCallback执行之前还是之前Stream stream = request.GetRequestStream()？
public HttpWebRequest GetRequest()
{
CookieContainer cookieContainer = new CookieContainer();
// Create a request to the server
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(_remoteUrl);
#region Set request parameters
request.Method = _context.Request.HttpMethod;
request.UserAgent = _context.Request.UserAgent;
request.KeepAlive = true;
request.CookieContainer = cookieContainer;
request.PreAuthenticate = true;
request.AllowAutoRedirect = false;
#endregion
// For POST, write the post data extracted from the incoming request
if (request.Method == "POST")
{
Stream clientStream = _context.Request.InputStream;
request.ContentType = _context.Request.ContentType;
request.ContentLength …假设你有这样的代码:
<html>
<head>
</head>
<body>
<div id="parentDiv" onclick="alert('parentDiv');">
<div id="childDiv" onclick="alert('childDiv');">
</div>
</div>
</body>
</html>?
parentDiv当我点击" childDiv我怎么能这样做？" 时,我不想触发点击事件？

另外,这两个事件的执行顺序是什么？
List<T>有一个调用的方法ForEach,它对每个元素执行传递的操作.
var names = new List<String>{ "Bruce", "Alfred", "Tim", "Richard" };
names.ForEach(p => { Console.WriteLine(p); });
但是,如果names不是一个List<T>但是IList<T>,IList<T>没有像这样的方法ForEach.还有其他选择吗？
closest()将通过测试元素本身并遍历DOM树中的祖先来获得与选择器匹配的第一个元素.但我想知道是否有任何方法可以将结果排除在外(我的意思是得到它的父母).
让我举个例子.请检讨一下.
<div id='div1' class="container">
<div id="div2" class="container">
<!--many nested div.container as it directly or indirectly children -->
</div>
<div id="div3" class="container">
<!--many nested div.container as it directly or indirectly children -->
</div>
</div>
$(function() {
$('div.container').on('mouseover', function(e){
//I only want to select the first parent with the class container.
//closest include the this element.
console.log($(this).closest('.container').attr('id'));
});
});
我不熟悉Less.在我的理解中,我认为Less可以将less格式文件转换为标准css文件(如果我错了,请纠正我).现在我有一个问题如下.
比如你会产生100个CSS类,如下面的(来自.span1于.span100在一个CSS文件).我想知道是否less可以像这样生成一个CSS文件？
...
.span5 {
width: 5%;
}
.span4 {
width: 4%;
}
.span3 {
width: 3%;
}
.span2 {
width: 2%;
}
.span1 {
width: 1%;
}
我总是感到困惑clear: left,clear: right并clear: both在CSS.我知道clear: both它意味着它不允许自身两侧浮动元素.
我在这里做了一些测试.我认为布局会如下所示,因为B使用clear: both.但事实并非如此.有人能告诉我为什么吗？

我知道这已被问过几百次,但是,我似乎无法掌握这个概念 prototype
这是我的示例脚本
var config = {
writable: true,
enumerable: true,
configurable: true
};
var defineProperty = function(obj, name, value) {
config.value = value;
Object.defineProperty(obj, name, config);
}
var man= Object.create(null);
defineProperty(man, 'sex', "male");
var person = Object.create(man);
person.greet = function (person) {
return this.name + ': Why, hello there, ' + person + '.'
}
var p=Object.getPrototypeOf(person);
alert(p.sex);//shows male
person.prototype.age=13;//why there is a error said the prototype is undefined? I thought it supposed be man object...
var child=function(){}
child.prototype.color="red";//why …所有,我试图根据一些工作样本申请Twitter typeahead并Bloodhound进入我的项目,但我无法理解下面的代码.
datumTokenizer: Bloodhound.tokenizers.obj.whitespace('songs'),
queryTokenizer: Bloodhound.tokenizers.whitespace,
原始代码如下所示.
var songlist = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.obj.whitespace('songs'),
queryTokenizer: Bloodhound.tokenizers.whitespace,
limit: 10,
remote: '/api/demo/GetSongs?searchTterm=%QUERY'
});
该公文只是说:
datumTokenizer - 具有签名(datum)的函数,用于将数据转换为字符串标记数组.需要.
queryTokenizer - 具有签名(查询)的函数,用于将查询转换为字符串标记数组.需要.
这是什么意思 ？有人可以帮忙告诉我更多关于它的信息,以便我更好地理解吗？
