谷歌地图 - 点击别针后标记部分

Question

我的页面有 2 个面 -

一方面我有部分。每一个都是包含文本和位置的旅行中的一天。另一方面，我有一个谷歌地图，上面有参考部分的图钉。

我希望允许用户单击图钉，页面将滚动到相关部分，并使用背景颜色绘制该部分。

Ans 也相反 - 当用户点击某个部分时，相关的 pin 会改变他的颜色。

我不知道如何使用 Google-Maps...

这是我的脚本代码：

<!-- Google map -->

    <script type="text/javascript">

Answer 1

我刚刚做了一个基本的演示。

主要思想是panTo() 标记和scrollTop() 到您单击的日期块。

编辑：在 DayInfo 数组中包含倾斜和内容。现在您可以在 infowindow 中构建您想要的内容。

var map;
var StartPoint = new google.maps.LatLng(50, 10);

var DayInfo = [{
    ID: "day1",
    Title: "Title1",
    Content: "Content1",
    Location: new google.maps.LatLng(51.72977747627091, 6.605224609375),
  },
  {
    ID: "day2",
    Title: "Title2",
    Content: "Content2",
    Location: new google.maps.LatLng(52.78551578550006, 13.460693359375),
  },
  {
    ID: "day3",
    Title: "Title3",
    Content: "Content3",
    Location: new google.maps.LatLng(50.292175137097736, 14.32861328125),
  },
  {
    ID: "day4",
    Title: "Title4",
    Content: "Content4",
    Location: StartPoint
  }
]

var DaysMarker = [];

function initialize() {
  var mapOptions = {
    center: StartPoint,
    zoom: 7,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };

  map = new google.maps.Map(document.getElementById("map"), mapOptions);

  DayInfo.forEach(function(dayInfo, index) {
    var marker = new google.maps.Marker({
      position: dayInfo.Location,
      map: map,
      isOpended: false,

      Open: function() {
        if (!this.isOpended) {
          this.infowindow.open(map, marker)
          this.isOpended = true
        }
        map.panTo(this.position)
      }
    })

    marker.infowindow = new google.maps.InfoWindow({
      content: '<div id="iw-container">' +
        '<h1>' + dayInfo.Title + '</h1>' +
        '<div class="iw-title">' +
        'Day' + (index + 1) + '<br>' +
        dayInfo.Content +
        '</div>' + '</div>',
      maxWidth: 350
    });

    marker.addListener('click', function() {
      if (this.isOpended) {
        this.infowindow.close()
        this.isOpended = false
      } else {
        this.Open()
        // var offsetTop = $('.day').get(index).offsetTop;
        $('html, body').animate({
          // scrollTop: offsetTop
          scrollTop: $('#' + dayInfo.ID).offset().top
        }, '500');
      }
    })

    DaysMarker.push(marker)
  })
}

$(function() {
  initialize()

  $('.day').on('click', function() {
    var index = $(this).index();
    DaysMarker[index].Open()
    // var offsetTop = $('.day').get(index).offsetTop;
    $('html, body').animate({
      // scrollTop: offsetTop
      scrollTop: $(this).offset().top
    }, '500');
  })
})

* {
  padding: 0;
  margin: 0;
}

body>div {
  position: relative;
  height: 100vh;
  vertical-align: top;
}

#map {
  width: 70%;
  position: fixed !important;
  right: 0;
  top: 0;
}

#days {
  margin-left: -4px;
  width: 30%;
  display: inline-block;
}

.day {
  height: 100vh;
  outline: 1px blue solid;
}
