Question

我想验证一个需要在格式中接受ony的文本框日期在YYYY-MM-DD HH：MM使用

<!DOCTYPE html>
<html>
<body>

<form action="/action_page_post.php" method="post">
  <input type="text" name="fname" required>
  <input type="submit" value="Submit">
</form>

<p>If you click submit, without filling out the text field,
your browser will display an error message.</p>

</body>
</html>

如果某些内容不是所述格式，它应该变为红色或发光。

Answer 1

这将测试

图案
有效日期

＆＃13;

boom ()

＆＃13;

function isValid(str) {
  var isPattern = /^20[1-9][0-9]-[0-1][0-2]-[0-3][0-9] [0-2][0-4]:[0-5][0-9]$/.test(str);
  if (!isPattern) return false;
  var d = new Date(str);
  return (!isNaN(d));
}
window.onload=function() {
  document.querySelector("input[name=date]").onkeyup=function() {
    var val = this.value;
    this.className = isValid(val)?"":"glow"
  }
}

＆＃13;

.glow { background-color:pink }

Answer 2

如何掩盖呢？

JSfiddle

＆＃13;

ISO Date: <input type="text" value="" data-mask="____-__-__  __:__"/>

＆＃13;

    string data = new WebClient().DownloadString("http://www.myfxbook.com/rss/forex-economic-calendar-events");
        XDocument xdoc = XDocument.Parse(data);

        //selecting table rows
        var tablerows = from tr in xdoc.Descendants("tr")
                        select tr;


        //extarct the headers
        var headings = from th in tablerows.Descendants("th")
                       select th.Value;
        //extract column data 
        var values = from td in tablerows.Descendants("td")
                     select td.Value;
        //Creating pairs
        var pairs = Enumerable.Zip(headings, values, (name, value)
                     => new Tuple<string, string>(name, value));

        foreach(var item in values)
        {
            Console.WriteLine(item);
        }
        Console.ReadLine();
