Question

<script type="text/javascript">

  var decodeEntities = (function() {
      // this prevents any overhead from creating the object each time
      var element = document.createElement('div');

      function decodeHTMLEntities (str) {
        if(str && typeof str === 'string') {
          // strip script/html tags
          str = str.replace(/<script[^>]*>([\S\s]*?)<\/script>/gmi, '');
          str = str.replace(/<\/?\w(?:[^"'>]|"[^"]*"|'[^']*')*>/gmi, '');
          element.innerHTML = str;
          str = element.textContent;
          element.textContent = '';
        }

        return str;
      }

      return decodeHTMLEntities;
    })();   
var points_data = JSON.parse(decodeEntities("<%= (data) %>"));


  var points = [];

  for(var i in points_data){
    var p = {"type":"line","showInLegend":"true"};
    p.name = i;
    //alert(p.name);
    p.dataPoints = [];
    for(var j=0; j<points_data[i].length; j++)
    {
        //alert(new Date(points_data[i][j].dateTime));
        //alert(getTime());
        //alert(points_data[i][j].value);
        var str = points_data[i][j].dateTime;
        alert(str);
        var sim = moment(str,"yyyy-M-D H:M:S").format('x');
        alert(sim);
        p.dataPoints.push({x: sim, y: parseFloat(points_data[i][j].value)});
    }
    points.push(p);

  }
</script>

它给我无效的日期错误。我怎样才能将这个字符串转换为   毫秒，如＆＃34; 1467172803000＆＃34;

我的Json有这样的数据：

现在我正在使用时刻代替日期其节目仍然是＆＃34; Inavlid date＆＃34;

Answer 1

查看Date()的JS文档。您可以使用getTime()方法。

＆＃13;

var str = "2016-06-29 01:07:18";
var sim = new Date(str).getTime();
alert(sim);

＆＃13;

Answer 2

您可以使用var miliSeconds = Date.parse(sim)

January 1, 1970

这将返回2016-06-29 01:07:18与您的日期1467144438000

之间的毫秒数

<强>输出

public static class backgroundTask extends AsyncTask<String, String, String[]> { @Override protected void onPreExecute() { //do something before putting values in database } @Override protected String[] doInBackground(String... f_url) { //call php api here with the arguments String url = "YOUR_PHP_API_URL_WITH_ARGUMENTS"; HttpClient client = new DefaultHttpClient(); try { client.execute(new HttpGet(url)); } catch (IOException e) { e.printStackTrace(); } return f_url; } @Override protected void onPostExecute(String[] f_url) { //do something after putting values in database } }

Answer 3

使用moment.js。

<script>
var str = "2016-06-29 01:07:18";
var sim = moment(str,"yyyy-M-D H:M:S").format('x');
alert(sim);
</script>

使用javascript的字符串到日期毫秒？
