将滚动条添加到svg容器

Question

我正在使用GetOrgChart为我的公司制作组织结构图,但我遇到了一个小问题.

如果SVG它比容器大,我们希望添加一个滚动条,以便您可以使用它滚动,因为这比用鼠标拖动它要快得多.

我试过这个例子但是无法使它工作.

有没有办法实现我正在寻找的东西？

下面的示例比我们的实际图表小,但它应该足以表示问题.

var peopleElement = document.getElementById("people");
var orgChart = new getOrgChart(peopleElement, {
  primaryFields: ["name", "title", "phone", "mail"],
  photoFields: ["image"],
  scale: 0.4,
  dataSource: [{

$('.get-left,.get-down,.get-up,.get-right').remove();

$(document).ready(function() {

#people {

  height: 90%;
  border:1px solid #000;

你可以看看这个jsfiddle..get-oc-c如果需要,容器会显示滚动条:

.get-oc-c {
  overflow: auto !important;
}

并且SVG图表元素被包装在一个div中,该div被调整大小以容纳整个图表:

function wrapChart() {
  ...
  $("svg").wrap("<div id='svgContainer'></div>");
  ...
}

#svgContainer {
  overflow: visible;
}

该wrapChart方法在updatedEvent.中调用.禁用图表移动选项以删除侧面的箭头并防止平移:

var orgChart = new getOrgChart(peopleElement, {
  enableMove: false,
  ...
});

原始显示似乎有效但是为包装元素获取正确的大小值很困难(jsfiddle中使用的表达式非常经验),当窗口调整大小,链接展开/折叠时,它变得更加复杂当图表缩放时.一些调整大小使用动画,因此计算必须考虑到获得最终值之前的延迟.

jsfiddle显示了一些简单的代码,用于在展开/折叠节点后恢复滚动位置,但是需要对其进行改进.我没有编写代码来解释窗口大小调整和缩放.

考虑到使滚动条表现正常所需的工作量,最好使用组件提供的平移和移动功能.您还可以联系组件的创建者并要求他们添加滚动条选项.
