我已经开始在我的html页面中使用morris.js折线图了.有没有办法将y轴设置为只包含整数？现在它显示十进制数字,但我的数据集只包含整数.

我尝试在Visual Studio 2015中使用新的npm支持,但是遇到了一些问题.我位于公司防火墙后面.

我试图从package.json文件中添加"grunt",并且可以看到与npm相关的输出.

我试图使用angular添加一些搜索结果的突出显示.我发现UI.Utils中的Highlight功能给出了我想要的结果.但这些例子都在使用ng-bind-html-unsafe.有没有办法使用这种模板方法？

<div ng-app>
    <div ng-controller="searchController">
        <input ng-model="query"/>

        <div class="t">
            <div class="tr" ng-repeat="person in result">
                <div class="td">{{person.FirstName | highlight}}</div>
                <div class="td">{{person.LastName | highlight}}</div>
            </div>
        </div>    
    </div>
</div>

我正在尝试使用异步模式来执行SQL命令并返回DataTable.有人可以请教如何解决这个问题？

这是我的代码:

    private static async Task<DataTable> ExecuteAsync(Connections connection, SqlBuilder sql)
    {
        using (SqlConnection conn = new SqlConnection(GetConnectstring(connection)))
        {
            await conn.OpenAsync();
            using (SqlCommand cmd = new SqlCommand(sql.Query, conn))
            {
                foreach (var parameter in sql.ColumnValues.Where(d => !d.Name.StartsWith("#")))
                {
                    cmd.Parameters.AddWithValue(parameter.Name, parameter.Value);
                }

                //Why am I getting a deadlock when executing the next line?
                using (SqlDataReader reader = await cmd.ExecuteReaderAsync())
                {
                    DataTable dt = new DataTable();
                    dt.Load(reader);
                    return dt;
                }
            }
        }
    }

最好的问候,托马斯

假设我有这样的文字：

$scope.text = 'This is the first line\nthis is the next line';

我想在使用 angular 的 div 标签中显示它

<div>{{text}}</div>

如何显示这个文本格式与换行？现在它显示如下：
