Question

如何在悬停时使每个SVG部分变大。我试图复制这个交互式地图的方式：http://goo.gl/orvyYI

我在这里创建了一个基本的交互式地图，用于测试：

<?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 19.1.0, SVG Export Plug-In . SVG Version: 6.00 Build 0)  -->
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="800px"
     height="600px" viewBox="0 0 800 600" style="enable-background:new 0 0 800 600;" xml:space="preserve">
<style type="text/css">
    .st0{fill:#C1C1C0;}
    .st1{fill:#0FB5CB;}
    .st2{fill:#46B649;}
</style>
<g id="Layer_1">
    <polygon class="st0" points="76.6,96.1 745.6,96.1 745.6,543.7 188.3,543.7   "/>
</g>
<g id="landmarks-test">
    <rect id="1" x="495.2" y="130.6" class="section" width="233.1" height="83.4"/>
    <rect id="2" x="495.2" y="235.4" class="section" width="233.1" height="95.9"/>
    <rect id="3" x="495.2" y="345.8" class="section" width="233.1" height="84.1"/>
</g>
</svg>

我尝试使用transform: matrix()实现他们的方式，并尝试了transform: scale()但没有成功。

Answer 1

您可以使用CSS将单个SVG元素与class='section'对齐，并对其应用所需的缩放变换。向元素添加transition可使其平滑增长。

transform-origin设置对整个部分至关重要，因为它指定了应该用作变换原点的点。

.section:hover {
  transform: scale(1.2);
}
.section {
  transition: all 1s;
  transform-origin: 50% 50%;
}

$(document).ready(function() {
  $('.section').on('click', function(event) {
    var sectionID = $(this).attr('id');
    // Select the relevant popup window that has the same ID as the sectionID
    var popupWindow = $('.popup-window.lot-' + sectionID);
    $('.popup-window').not(popupWindow).hide();
    var leftPos = $(this).position().left;
    var topPos = $(this).position().top;
    popupWindow.css('top', topPos - 200).css('left', leftPos - 100).show();
  });

  $('.close-button').click(function(event) {
    $('.popup-window').hide();
  });

});

body {
  position: relative;
  margin: 0, padding: 0;
}
.section:hover {
  fill: yellow;
}
.popup-window {
  width: 400px;
  height: 200px;
  background: #accee2;
  display: none;
  position: absolute;
  z-index: 100;
  top: 0;
  border: 1px solid #ccc;
  border: 1px solid rgba(0, 0, 0, .2);
  border-radius: 6px;
  -webkit-box-shadow: 0 5px 10px rgba(0, 0, 0, .2);
  box-shadow: 0 5px 10px rgba(0, 0, 0, .2);
  padding: 20px;
}
.section:hover {
  transform: scale(1.2);
}
.section {
  transition: all 1s;
  transform-origin: 50% 50%;
}

您链接的网站上看到的效果有点复杂，因为最后有一个混蛋，它需要transition-timing-function（或）关键帧{{1}的立方贝塞尔曲线}。

animation

transition-timing-function: cubic-bezier(.87,1,.6,.19);

$(document).ready(function() {
  $('.section').on('click', function(event) {
    var sectionID = $(this).attr('id');
    // Select the relevant popup window that has the same ID as the sectionID
    var popupWindow = $('.popup-window.lot-' + sectionID);
    $('.popup-window').not(popupWindow).hide();
    var leftPos = $(this).position().left;
    var topPos = $(this).position().top;
    popupWindow.css('top', topPos - 200).css('left', leftPos - 100).show();
  });

  $('.close-button').click(function(event) {
    $('.popup-window').hide();
  });

});

body {
  position: relative;
  margin: 0, padding: 0;
}
.section:hover {
  fill: yellow;
}
.popup-window {
  width: 400px;
  height: 200px;
  background: #accee2;
  display: none;
  position: absolute;
  z-index: 100;
  top: 0;
  border: 1px solid #ccc;
  border: 1px solid rgba(0, 0, 0, .2);
  border-radius: 6px;
  -webkit-box-shadow: 0 5px 10px rgba(0, 0, 0, .2);
  box-shadow: 0 5px 10px rgba(0, 0, 0, .2);
  padding: 20px;
}
.section:hover {
  transform: scale(1.2);
}
.section {
  transition: all 1s;
  transition-timing-function: cubic-bezier(.87,1,.6,.19);
  transform-origin: 50% 50%;
}

Firefox在给定百分比值时似乎不尊重<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="popup-window lot-1"> <a href="/for-sale/show/1">Lot Number: 1</a> <h5>Section Size: 500</h5> <button class="close-button">Close</button> </div> <div class="popup-window lot-2"> <a href="/for-sale/show/2">Lot Number: 2</a> <h5>Section Size: 600</h5> <button class="close-button">Close</button> </div> <div class="popup-window lot-3"> <a href="/for-sale/show/3">Lot Number: 3</a> <h5>Section Size: 450</h5> <button class="close-button">Close</button> </div> <?xml version="1.0" encoding="utf-8" ?>  <svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="800px" height="600px" viewBox="0 0 800 600" style="enable-background:new 0 0 800 600;" xml:space="preserve"> <style type="text/css"> .st0 { fill: #C1C1C0; } .st1 { fill: #0FB5CB; } .st2 { fill: #46B649; } </style> <g id="Layer_1"> <polygon class="st0" points="76.6,96.1 745.6,96.1 745.6,543.7 188.3,543.7 " /> </g> <g id="landmarks-test"> <rect id="1" x="495.2" y="130.6" class="section" width="233.1" height="83.4" /> <rect id="2" x="495.2" y="235.4" class="section" width="233.1" height="95.9" /> <rect id="3" x="495.2" y="345.8" class="section" width="233.1" height="84.1" /> </g> </svg>设置，因此我们必须为每个子项使用特定的像素值。单个值的计算方式为transform-origin位置+ x / 2和width位置+ y / 2。

height

.section:nth-child(1){
  transform-origin: 612px  172px;
}
.section:nth-child(2){
  transform-origin: 612px  283px;
}
.section:nth-child(3){
  transform-origin: 612px  388px;
}

$(document).ready(function() {
  $('.section').on('click', function(event) {
    var sectionID = $(this).attr('id');
    // Select the relevant popup window that has the same ID as the sectionID
    var popupWindow = $('.popup-window.lot-' + sectionID);
    $('.popup-window').not(popupWindow).hide();
    var leftPos = $(this).position().left;
    var topPos = $(this).position().top;
    popupWindow.css('top', topPos - 200).css('left', leftPos - 100).show();
  });

  $('.close-button').click(function(event) {
    $('.popup-window').hide();
  });

});

body {
  position: relative;
  margin: 0, padding: 0;
}
.section:hover {
  fill: yellow;
}
.popup-window {
  width: 400px;
  height: 200px;
  background: #accee2;
  display: none;
  position: absolute;
  z-index: 100;
  top: 0;
  border: 1px solid #ccc;
  border: 1px solid rgba(0, 0, 0, .2);
  border-radius: 6px;
  -webkit-box-shadow: 0 5px 10px rgba(0, 0, 0, .2);
  box-shadow: 0 5px 10px rgba(0, 0, 0, .2);
  padding: 20px;
}
.section:hover {
  transform: scale(1.2);
}
.section {
  transition: all 1s;
  transition-timing-function: cubic-bezier(.87, 1, .6, .19);
}
.section:nth-child(1) {
  transform-origin: 612px 172px;
}
.section:nth-child(2) {
  transform-origin: 612px 283px;
}
.section:nth-child(3) {
  transform-origin: 612px 388px;
}

需要注意的另一件事是，如this CodePen Article by Ana Tudor中所述，SVG元素上的CSS转换在IE中不起作用。

此<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="popup-window lot-1"> <a href="/for-sale/show/1">Lot Number: 1</a> <h5>Section Size: 500</h5> <button class="close-button">Close</button> </div> <div class="popup-window lot-2"> <a href="/for-sale/show/2">Lot Number: 2</a> <h5>Section Size: 600</h5> <button class="close-button">Close</button> </div> <div class="popup-window lot-3"> <a href="/for-sale/show/3">Lot Number: 3</a> <h5>Section Size: 450</h5> <button class="close-button">Close</button> </div> <?xml version="1.0" encoding="utf-8" ?>  <svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="800px" height="600px" viewBox="0 0 800 600" style="enable-background:new 0 0 800 600;" xml:space="preserve"> <style type="text/css"> .st0 { fill: #C1C1C0; } .st1 { fill: #0FB5CB; } .st2 { fill: #46B649; } </style> <g id="Layer_1"> <polygon class="st0" points="76.6,96.1 745.6,96.1 745.6,543.7 188.3,543.7 " /> </g> <g id="landmarks-test"> <rect id="1" x="495.2" y="130.6" class="section" width="233.1" height="83.4" /> <rect id="2" x="495.2" y="235.4" class="section" width="233.1" height="95.9" /> <rect id="3" x="495.2" y="345.8" class="section" width="233.1" height="84.1" /> </g> </svg>和matrix设置的transform: scale(1.2)等效值如下：（Logic is explained here）

transform-origin

.section:nth-child(1):hover {
  transform: matrix(1.2, 0, 0, 1.2, -122.4, -34.46);
}
.section:nth-child(2):hover {
  transform: matrix(1.2, 0, 0, 1.2, -122.4, -56.67);
}
.section:nth-child(3):hover {
  transform: matrix(1.2, 0, 0, 1.2, -122.4, -77.57);
}

$(document).ready(function() {
  $('.section').on('click', function(event) {
    var sectionID = $(this).attr('id');
    // Select the relevant popup window that has the same ID as the sectionID
    var popupWindow = $('.popup-window.lot-' + sectionID);
    $('.popup-window').not(popupWindow).hide();
    var leftPos = $(this).position().left;
    var topPos = $(this).position().top;
    popupWindow.css('top', topPos - 200).css('left', leftPos - 100).show();
  });

  $('.close-button').click(function(event) {
    $('.popup-window').hide();
  });

});

body {
  position: relative;
  margin: 0, padding: 0;
}
.section:hover {

.popup-window {
  width: 400px;
