小编Sam*_*ack的帖子

假设我有一个字符串1,2,3, 我想删除最后一个字符串,或者如果字符串看起来像,1,2,3,或者 ,1,2,3我仍然希望得到1,2,3我的结果.请尽量在答案中做一点解释.我不只是想要复制粘贴的东西而不理解它.谢谢.

我有一个场景是我需要触发SelectedIndexChangedwinform的combox 的事件,即使旧的和新的索引是相同的..我不能使用,SelectionChangeCommited因为值是以编程方式设置..它不会被解雇.即使旧的和相同的索引相同,是否有机会强制'SelectedIndexChanged'开火？

我正在尝试通过 docker 运行一个简单的 Web api。

我已遵循文档中提到的所有步骤。

FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out

# Build runtime image
FROM mcr.microsoft.com/dotnet/core/aspnet:2.2
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "aspnetapp.dll"]

截屏：

我用来通过 docker 运行 api 的命令：

docker build -t aspnetapp .
docker run -d -p 8080:80 --name myapp aspnetapp

请注意，当我在命令行中执行以下命令时，API 会起作用，因此 API …

现在这是我得到的回应updateMany()

我有一个WebMethod,它获取我想在DataSet中填充DropDown的数据.目前我正在使用硬编码对象填充下拉列表.但我想用webmethod返回的数据替换这个硬编码对象.

 [System.Web.Services.WebMethod]
         public static string GetDropDownDataWM(string name)
         {
             //return "Hello " + name + Environment.NewLine + "The Current Time is: "
             //    + DateTime.Now.ToString();

             var msg = "arbaaz";

             string[] name1 = new string[1];
             string[] Value = new string[1];
             name1[0] = "@Empcode";
             Value[0] = HttpContext.Current.Session["LoginUser"].ToString().Trim();
             DataSet ds = new DataSet();
             dboperation dbo = new dboperation();
             ds = dbo.executeProcedure("GetDropDownsForVendor", name1, Value, 1);

             return ds.GetXml(); 

         }

客户端(更新1):

  <script type = "text/javascript">
    function GetDropDownData() {
        var myDropDownList = $('.myDropDownLisTId');

        $.ajax({
            type: "POST",
            url: "test.aspx/GetDropDownDataWM", …

我有一个字符串,看起来BAT | CAT | RAT | MAT我想把这个字符串分成4个部分然后存储在4个不同的变量中分别说.. @ a,@ b,@ c,@ d.我在代码中执行此操作,但我不确定如何在sql中执行此操作？谢谢.

我已经使用命令安装了 nodemon：

npm install nodemon -g

做完，我改变"start": "node ./bin/www"到"start": "nodemon ./bin/www"

运行时控制台输出 npm start：

[nodemon] 1.11.0
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*
[nodemon] starting `nodemon  ./bin/www ./bin/www`
[nodemon] 1.11.0
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*
[nodemon] starting `nodemon  ./bin/www ./bin/www ./bin/www`

[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*
[nodemon] starting `nodemon  ./bin/www ./bin/www ./bin/www ./bin/www`
and so on....

我哪里错了？请记住，这是我在 nodejs …

我有一个文本框和旁边的按钮.我想通过Jquery ajax调用webmethod发送文本框的内容并获取相同的大写值并在alert中显示.到目前为止,我有这个代码,但它不起作用.

JAVASCRIPT:

function CallWM()
    {          

        var name = $('#name').val();         


        RealCallWM(name);


    }
    function RealCallWM(name) {

        $.ajax({
            url: 'Register.aspx/UpperWM',
            type: 'POST',
            contentType: 'application/json; charset=utf-8',
            data: { name: JSON.stringify(name) },
            success: OnSuccess(response),
            error: function (response) {
                alert(response.responseText);
            }
        })
    };

HTML:

  Name:    <input id="name" type="text" /> 
<input id="Button1" type="button" value="button" onclick="CallWM();"/></div>
    </form>

WEB方法:

 [WebMethod]
        public static string UpperWM(string name )
        {
            var msg=name.ToUpper();
            return (msg);
        }

我需要一个在所有浏览器中看起来几乎相同的 FileUpload，即也在 chrome 中显示文件输入字段。所以我使用自定义 FileUpload 与此代码..

CSS

    <style type="text/css">



        #FileUpload {
    position:relative;
            top: -4px;
            left: 0px;
        }

#BrowserVisible {
    position: absolute;
    top: -15px;
    left: 0px;
    z-index: 1;
    background:url(upload.gif) 100% 0px no-repeat;
    height:26px;
    width:240px;
}

#FileField {
    width:155px;
    height:22px;
    margin-right:85px;
    border:solid 1px #000;
    font-size:16px;
}

#BrowserHidden {
    position:relative;
    width:240px;
    height:26px;
    text-align: right;
    -moz-opacity:0;
    filter:alpha(opacity: 0);
    opacity: 0;
    z-index: 2;
}

    </style>

Javascript

<script src="zoom/jquery-1.10.2.min.js"></script>
<script type="text/javascript">
    $('.custom-upload input[type=file]').change(function () {
        $(this).next().find('input').val($(this).val());
    });

</script>

HTML

<div id="FileUpload">
    <input type="file" size="24" id="BrowserHidden" runat="server" …

这甚至可能吗？我有一个带有某些文本框等的webform和一个文件上传元素.我正在尝试使用.ajax()方法将数据发送到webmethod .在我看来,不可能以这种方式将文件内容发送到web方法.我甚至都无法点击网络方法.

script type="text/javascript">
    var btn;
    var span;
    $(document).ready(function (e) {

        $('#btnsave').on('click', function (event) {

            Submit();
            event.preventDefault();
        });
    })

    function Submit() {

        $.ajax({
            type: "POST",
            url: "SupplierMst.aspx/RegisterSupplier",
            data: "{'file' : " + btoa(document.getElementById("myFile").value) + ",'biddername':" + document.getElementById("txtsuppliername").value + "}",
            async: true,
            contentType: "application/json; charset=utf-8",
            success: function (data, status) {
                console.log("CallWM");
                alert(data.d);
            },
            failure: function (data) {
                alert(data.d);
            },
            error: function (data) {
                alert(data.d);
            }
        });

    }
    </script>
