Answer 1

This code will disable custom dates in date range picker.

var naArray = ["20170822", "20170823", "20170824", "20170825"];
  function isDateAvailable(date){
    return naArray.indexOf(date.format('YYYYMMDD')) > -1;
  }

 $('input[name="daterange"]').daterangepicker({
  isInvalidDate: isDateAvailable
 });

好的...目前尚不清楚您想要什么，但听起来您只是想知道如何使用ASP设置javascript数组变量，在这种情况下，您只需编写：

var some_date_range = [<%= name_of_your_array_variable_from_asp %>];
