小编Hak*_*tık的帖子

我有一个divHTML,里面写着一些文字.
将div通过设置它的创建X,Y坐标和height和width.
我想绘制一个三角形叠加,div这样我的内容就不会丢失.
我不能改变的X,Y坐标为我其他div的定位是基于此div.
使用多重div方法生成三角形似乎也不可行,因为我不确定div我将在哪个文本中写下......

有人可以建议我如何做到这一点..？

我是WPF新手,而且我的窗口不再可点击了.

我无法单击一个按钮,我无法编辑文本框.

我正在使用Visual Studio 2015(也是新的).

可能是什么原因？

这里有一些代码:

我从搜索中找不到任何有类似问题的人:

我正在尝试使用HttpClient从服务器获取XML,但我的UI在"task.Wait()"行奇怪地冻结.这是代码:

public void register() {
    String data = "register=" + (accountName) + "&email0=" +
                (email) + "&email1=" + (otherEmail);
    var task = MakeRequest(data);
    task.Wait();                  //freezes here
    var response = task.Result;
    String resultstring = response.Content.ReadAsStringAsync().Result;
}

private static async Task<System.Net.Http.HttpResponseMessage> MakeRequest(String data)
{
     var content = new StringContent(data, Encoding.UTF8, "application/x-www-form-urlencoded");
     var httpClient = new System.Net.Http.HttpClient();
     System.Net.Http.HttpResponseMessage responseMessage=null;
     try
     {
         responseMessage = await httpClient.PostAsync(server, content);
     }
     catch(Exception ex)
     {
         responseMessage.ReasonPhrase = string.Format("RestHttpClient.SendRequest failed: {0}", ex);
     }
        return responseMessage;
 }

任何帮助是极大的赞赏!

我有这个样本:

代码HTML:

<div class="dropzone dz-clickable" id="myDrop">
     <div class="dz-default dz-message" data-dz-message="">
          <span>Upload or drag patient photo here</span>
     </div>
</div>

代码JS:

 Dropzone.autoDiscover = false;
 var myDropzone = new Dropzone("div#myDrop", {
   addRemoveLinks: true,
   url: "#",
   maxFiles: 1,
   init: function() {

     this.on("maxfilesexceeded", function(file) {
       alert("You are not allowed to chose more than 1 file!");
       this.removeFile(file);

     });

     this.on("addedfile", function(file) {
       myDropzone.options.removefile.call(myDropzone, mockFile);
       //  I want to delete an existing element
     });

   }

 var fileName = $('#profilePicture').val();
 var mockFile = {
   name: fileName,

我想了解为什么当属性是原型时,knockout的行为会有所不同,尤其重要的是,如何避免它,同时仍然使用原型.
我想要覆盖一些方法,因为我有一个我们要继承的基本视图模型

以下是我的意思

JSFIDDLE WITH PROTOTYPE [尝试输入第一个输入框,它将出现在另一个输入框中]

var viewModel = function(params) {
        this.params =  params;
    };
    viewModel.prototype.text = ko.observable(this.params  && this.params.initialText || '');


ko.components.register('message-editor', {
    viewModel: viewModel,
    template: 'Message: <input data-bind="value: text" /> '
            + '(length: <span data-bind="text: text().length"></span>)'
