小编RSi*_*lva的帖子

我想在MySQL数据库的所有表中搜索给定字符串的所有字段,可能使用以下语法:

SELECT * FROM * WHERE * LIKE '%stuff%'

可以这样做吗？

当点击图像时,我正试图将fadeout效果赋予div并删除div(id ="notification").

这就是我这样做的方式:

<a onclick="$("#notification").fadeOut(300,function() { $("#notification").remove(); });" class="notificationClose "><img src="close.png"/></a>

这似乎不起作用.我需要做些什么来解决这个问题？

我正在尝试使用网络服务器将html5画布内容保存到localhost.我在base64中获得了canvas值,然后将其发送到我的webservice.但是,当我将数据发送到Web服务时,我收到此错误,并且文件未保存:

415:"无法处理消息,因为内容类型'application/octet-stream'不是预期类型'text/xml; charset = utf-8'."

我究竟做错了什么？

Service.vb

Imports System.IO
Imports System.Drawing

Public Class Service
    Implements IService

    Public Sub New()
    End Sub


    Public Function savePictureBase64(bytes As Byte()) As Boolean Implements IService.savePictureBase64
        Dim fullOutputPath As String = "c:\temp\file.png"

        'get a temp image from bytes, instead of loading from disk
        'data:image/gif;base64,


        Dim imagem As Image
        Using ms As New MemoryStream(bytes)
            imagem = Image.FromStream(ms)
        End Using

        File.WriteAllBytes(fullOutputPath, (bytes))

        Return True


    End Function

End Class

<ServiceContract()>
Public Interface IService


    <OperationContract()>
    Function savePictureBase64(bytes As Byte()) …

我有这个功能,可以即时创建DIV.但现在,我想在onclick事件中销毁这个对象,但我只是不知道如何.

function creatediv(id) {

    var newdiv = document.createElement('div');
    newdiv.setAttribute('id', id);
    newdiv.onclick=function(){this=null;};  //bad function
    document.body.appendChild(newdiv);

} 

我错过了什么？

谢谢

我需要创建一个REST Web服务.为此我遵循了本教程:http://www.odata.org/blog/how-to-use-web-api-odata-to-build-an-odata-v4-service-without-entity-framework/

一切都运行良好,我还添加了BasicAuth,它就像一个手套.

现在,我的问题......这个web服务将与它的可能版本一起使用,因此我们决定实现一种版本系统.此外,我们希望客户端应用程序选择他们想要执行其操作的数据库.为此,我们认为拥有这种风格的URI会很好:

HTTP://本地主机/连接/北风/ API/1 /的DataRow

这是我的代码.我以前只定义了DataRow实体.现在我还定义了实体API和Connection.

如何实现我想要的URI /端点？到目前为止,这是我的代码.

文件:WebApiConfig.cs

    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.MapODataServiceRoute("odata", null, GetEdmModel(), new DefaultODataBatchHandler(GlobalConfiguration.DefaultServer));
            config.EnsureInitialized();
        }
        private static IEdmModel GetEdmModel()
        {
            //GlobalConfiguration.Configuration.Filters.Add(new BasicAuthenticationFilter());   // basicAutenthentication
            ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
            builder.Namespace = "Integration";
            builder.ContainerName = "DefaultContainer";
            builder.EntitySet<DataRow>("DataRow");
            builder.EntitySet<Connection>("Connection");
            builder.EntitySet<API>("API");
            var edmModel = builder.GetEdmModel();
            return edmModel;

我需要一个基于整数的字符串,它应该总是有5位数.

例:

myInteger = 999
formatedInteger = "00999"

在经典ASP中这样做的最佳方法是什么？

我正在创建一个应用程序来向Web服务提交一些XML.问题是我无法与网络服务进行通信.当我调用"request.GetRequestStream()"时,我收到此错误:

底层连接已关闭.发送时发生意外错误.

ex.Status = SendFailure {4}

要完全控制您的应用程序,您更喜欢GridView还是HTML表格？为什么？

例如,我需要在GridView/HTML表中创建每行的动态超链接.哪个对象更容易添加该功能(或其他像这样的功能)？

注意:我正在以编程方式创建我的数据集

此代码用于Chrome扩展程序.当我调用"showOrHideYT()"函数时,我得到一个"Uncaught ReferenceError:showOrHideYT未定义|(匿名函数)| onclick".

此代码将在页面中搜索youtube链接,它将在链接旁边添加一个按钮(它实际上是一个带有事件的div),以显示嵌入视频的iframe,非常类似于Reddit Enhancement Suite.考虑代码本身是不完整的.我只是想知道当我调用"showOrHideYT(frameZES12345)"函数时我错过了什么.

如果需要,我可以提供manifest.json.

谢谢

function showOrHideYT(id)
{
    var YTvidWidth  = 420;
    var YTvidHeight = 315;
    frameYT=getElementById(id);
    console.log(frameYT.style.visibility);
    if (frameYT.style.visibility == "hidden")
        {
        frameYT.style.width = YTvidWidth+"px"; 
        frameYT.style.height = YTvidHeight+"px"; 
        frameYT.style.visibility = "visible";
        }

我还可以做些什么来优化此查询？
