小编jmo*_*era的帖子

编辑XAML文件时,我注意到以下错误:

System.ObjectDisposedException occurred
  Message=Cannot access a disposed object.
Object name: 'FileCodeModel'.

为了调试这个,我运行了另一个Visual Studios实例和"Debug-> Attach to Process"到Visual studio的实例,其中显示了异常.

我能够在启动附加到进程的新实例中捕获异常.我遇到以下异常:

System.ObjectDisposedException occurred
  Message=Cannot access a disposed object.

任何人都会在你的XAML中遇到这个异常,你会怎么做才能修复它.

我有这样的功能:

exports.saveAction = function (req, res) {
    var conn = mysql.createConnection({
        host     : nconf.get("database:host"),
        //port: 3306,
        user     : nconf.get("database:username"),
        password : nconf.get("database:password"),
        database : nconf.get("database:database"),
        multipleStatements: true,
        //ssl: 'Amazon RDS'
    });
    var action = req.body;   
    conn.query('UPDATE actions SET ? WHERE Id = ?', 
                  [action, action.Id], function (err, result) {
        conn.end();
        if (err) throw err;
        res.writeHead(200, { "Content-Type": "application/json" });
        res.end("Updated Successfully");
    });
};

我返回"200",但它总是返回如下所示的错误子句:

$.ajax({
    url: "/api/action/SaveAction",
    type: "PUT",
    data: ko.toJSON(self.stripDownObj()),
    datatype: "json",
    contentType: "application/json; charset=utf-8",
    success: function (result) { …

我正在尝试设置注册和登录Hot Towel SPA应用程序.我已经基于asp.net单页面应用程序模板创建了SimpleMembershipFilters和ValidateHttpAntiForgeryTokenAttribute .

你怎么得到的

 @Html.AntiForgeryToken()

代码以Durandal SPA模式工作.

目前我有一个register.html

<section>
    <h2 data-bind="text: title"></h2>

    <label>Firstname:</label><input data-bind="value: firstName" type="text"  />
    <label>Lastname:</label><input data-bind="value: lastName" type="text"  />
    <label>Email:</label><input data-bind="value: emailAddress" type="text"  />
    <label>Company:</label><input data-bind="value: company" type="text"  />
    <br />
    <label>Password:</label><input data-bind="value: password1" type="password" />
    <label>Re-Enter Password:</label><input data-bind="value: password2" type="password" />
    <input type="button" value="Register" data-bind="click: registerUser" class="btn" />
</section>

register.js:

define(['services/logger'], function (logger) {
    var vm = {
        activate: activate,
        title: 'Register',
        firstName: ko.observable(),
        lastName: ko.observable(),
        emailAddress: ko.observable(),
        company: ko.observable(),
        password1: …

所以我试图将CKEditor的内联编辑与Knockout.js集成.我能够成功加载CKEditor和knockout.js.

我似乎无法获得ko.observable更新属性:

<script type="text/javascript">

    var viewModel = function () {
        var self = this;
        self.editorText = ko.observable('ABC');
        self.testNewValue = function () {
            console.log(this.editorText());
        };
    }

    ko.applyBindings(new viewModel());
</script>

这是html:

<div id="editable" contenteditable="true" data-bind="html: editorText">
</div>
<div>
    <input type="button" data-bind="click: testNewValue" value="test" />
</div>

无论您是否更新,console.log结果始终显示"ABC".注意:我也试过了data-bind="text: editorText"

所以我正在制作一些ajax帖子,它似乎在localhost上正常工作,但是当我将它发布到amazon上的ec2服务器时,我得到Uncaught SyntaxError:意外的令牌B.这似乎指向JSON解析失败.完全相同的数据库,相同的浏览器和相同的方法被调用.为什么它可以在本地而不是服务器上运行.

$.ajax({
                url: '@Url.Action("Action")',
                type: "POST",
                data: ko.toJSON(viewModel),
                dataType: "json",
                contentType: "application/json; charset:utf-8",
                success: function (result) {

                },
                error: function (xhr, textStatus, errorThrown) {
                    var errorData = $.parseJSON(xhr.responseText);
                    var errorMessages = [];

                    for (var key in errorData)
                    {
                        errorMessages.push(errorData[key]);
                    }
                    toastr.error(errorMessages.join("<br />"), 'Uh oh');
                }
            });

这是服务器端的基本布局:

[HttpPost]
        public JsonResult Action(ViewModel model)
        {
            try
            {

                Response.StatusCode = (int)HttpStatusCode.OK;
                return Json("Successfull");
            }
            catch (Exception ex)
            {
                logger.Log(LogLevel.Error, string.Format("{0} \n {1}", ex.Message, ex.StackTrace));
                Response.StatusCode = (int)HttpStatusCode.BadRequest;
                List<string> errors = new List<string>(); …

我有一个带有observable的简单模型类.我只是想订阅它的集合.这是我的代码:

var dto = function (data) {
    var self = this;
    self.Value1 = ko.observable(data.Value1);
    self.Value1.subscribe(function(){
         console.log('here');
    });   
};

首次设置Value1时,不会调用console.log(即ko.observable(data.Value1)

如何设置subribe函数在初始和更改时都会发生.

我正在尝试使用Jquery UI滑块,我可以在其中有多个句柄:

$(function () {
        var handlers = [25, 50, 75];
        $("#slider").slider({
            min: 0,
            max: 100,
            values: handlers,
            slide: function (evt, ui) {
                for (var i = 0, l = ui.values.length; i < l; i++) {
                    if (i !== l - 1 && ui.values[i] > ui.values[i + 1]) {
                        return false;
                    }
                    else if (i === 0 && ui.values[i] < ui.values[i - 1]) {
                        return false;
                    }
                }
            }
        });
    });

请注意,一个处理程序不能重叠,我需要在加载时动态设置处理程序,并在更改时保存处理程序位置.

我想要完成的事情是将处理程序之间的ui内容着色为不同的颜色.我附上了一张图片.

如果可能的话请提供建议.

我正在扩展IdentityUser,IdentityUserRole并且IdentityRole像这样:

public class ApplicationUser : IdentityUser
{
    public string FullName { get; set; }

    public virtual ICollection<ApplicationIdentityUserRole> Roles { get; } = new List<ApplicationIdentityUserRole>();
}

public class ApplicationIdentityUserRole : IdentityUserRole<string>
{
    public virtual ApplicationUser User { get; set; }
    public virtual ApplicationRole Role { get; set; }
}

public class ApplicationRole : IdentityRole
    {
        public virtual ICollection<ApplicationIdentityUserRole> Roles { get; } = new List<ApplicationIdentityUserRole>();
    }

并配置如下:

public class SmartAccountingSetUpContext : IdentityDbContext<ApplicationUser>
{
    public SmartAccountingSetUpContext(DbContextOptions<SmartAccountingSetUpContext> …

我正在从 aws-cli 开始部署：

"C:\Program Files\Amazon\AWSCLI\bin\aws.exe" deploy create-deployment --application-name App.Web --deployment-config-name CodeDeployDefault.OneAtATime --deployment-group-name Development-Staging-UAT --region us-west-2 --description "App.Web" --s3-location bucket=app-artifacts/development,bundleType=zip,key=Publish.zip

这确实启动了部署，但在 DownloadBundle 部分以错误结束：

:bucket option must not contain a forward-slash (/) 

修订位置 s3://app-artifacts/development/Publish.zip

我究竟做错了什么？

这是完整的错误:

Invalid data has been used to update the list item. The field you are trying to update may be read only.

我基本上尝试更新Sharepoint中的日历事件.

首先,我得到以下内容.

ClientContext clientContext = new ClientContext(deptUrl);
Web web = clientContext.Web;
List list = web.Lists.GetByTitle(deptCal);
clientContext.Load(list);

CamlQuery query = new CamlQuery();
query.ViewXml = "<View><Query><Where><IsNull><FieldRef Name='EndDate' /></IsNull></Where></Query><RowLimit>1</RowLimit></View>";

ListItemCollection allEventIds = list.GetItems(query);

clientContext.Load(allEventIds, 
items => items.Include(
     item => item["EventID"],
     item => item["EventDate"],
     item => item["EndDate"]
));

clientContext.ExecuteQuery();

接下来循环:

foreach (var item in allEventIds)
{
   Console.Write("EventId: {0} StartDate: {1}\n", item.FieldValues["EventID"], item.FieldValues["EventDate"]); …
