WeChat applet implements sorting function based on date and time

startDate: "2021-08-27" //Date year month day startTime: "10:15" //Start time endTime: "20:00" //End time

// Sort by date comparedate: function (property) {
    // console.log(property); 
    return function (a, b) { 
    var value1 = Date.parse(new Date(a[property])); //Convert to hexadecimal to get the date var value2 = Date.parse(new Date(b[property]));
    // console.log( value1 -value2);
      return value1 - value2; //value1-value2 are sorted from small to large and vice versa}
},

// Sort by time The time format is 10:00, so we use slice to intercept the first two digits of the string and compare the order of time by hour comparehour: function (property) {
  // console.log(property);
  return function (a, b) {
    var value1 = a.startTime.slice(0,2) //slice(0,2) gets the first two digits of the string for comparison var value2 = b.endTime.slice(0,2)
    // console.log(value1-value2)
   return value1 -value2 //value1-value2 is sorted from small to large and vice versa}
},
