Question

我有两个侧边栏。一个侧边栏给出了mysql查询的排序结果，另一个侧边栏给出了一个位置的方向。我试图交替mysql结果的行颜色和方向的行颜色。它使用此代码的方向工作，但不适用于mysql结果。任何人都知道如何让这个工作？感谢

Answer 1

side_bar条目不是表格，因此您为<tr>元素添加的CSS不适用。可能最简单的事情就是让他们成为一张桌子。

function calculateDistances(pt, closest, numberOfResults) {
  var service = new google.maps.DistanceMatrixService();
  var request = {
    origins: [pt],
    destinations: [],
    travelMode: google.maps.TravelMode.DRIVING,
    unitSystem: google.maps.UnitSystem.IMPERIAL,
    avoidHighways: false,
    avoidTolls: false
  };
  for (var i = 0; i < closest.length; i++) {
    request.destinations.push(closest[i].getPosition());
  }
  service.getDistanceMatrix(request, function(response, status) {
    if (status != google.maps.DistanceMatrixStatus.OK) {
      alert('Error was: ' + status);
    } else {
      var origins = response.originAddresses;
      var destinations = response.destinationAddresses;
      var outputDiv = document.getElementById('side_bar');
      var sidebarHtml = '<table>';

      var results = response.rows[0].elements;
      // save title and address in record for sorting
      for (var i = 0; i < closest.length; i++) {
        results[i].title = closest[i].title;
        results[i].address = closest[i].address;
        results[i].idx_closestMark = i;
      }
      results.sort(sortByDistDM);
      for (var i = 0;
        ((i < numberOfResults) && (i < closest.length)); i++) {
        closest[i].setMap(map);

        sidebarHtml += "<tr><td><a href='javascript:google.maps.event.trigger(closest[" + results[i].idx_closestMark + "],\"click\");'>" + results[i].title + '</a><br>' + results[i].address + "<br>" + results[i].distance.text + ' approximately ' + results[i].duration.text + "<br><a href='javascript:getDirections(customerMarker.getPosition(),&quot;" + results[i].address + "&quot;);'>Get Directions</a></td></tr>"

      }
      sidebarHtml += '</table>';
      outputDiv.innerHTML = sidebarHtml;
    }
  });
