Element.getScrollHeight介绍

[英]The height of the scroll view of an element.
[中]元素滚动视图的高度。

代码示例

代码示例来源：origin: com.google.gwt/gwt-servlet

/**
 * The height of the scrollable area of the document.
 * 
 * @return the height of the document's scrollable area
 */
public final int getScrollHeight() {
 // TODO(dramaix): Use document.scrollingElement when its available. See getScrollLeft().
 return getViewportElement().getScrollHeight();
}

代码示例来源：origin: com.google.gwt/gwt-servlet

@Override
protected void onStart() {
 scrollHeight = 0;
 // If the TreeItem is already open, we can get its scrollHeight
 // immediately.
 if (!opening) {
  scrollHeight = curItem.childSpanElem.getScrollHeight();
 }
 curItem.childSpanElem.getStyle().setProperty("overflow", "hidden");
 // If the TreeItem is already open, onStart will set its height to its
 // natural height. If the TreeItem is currently closed, onStart will set
 // its height to 1px (see onUpdate below), and then we make the TreeItem
 // visible so we can get its correct scrollHeight.
 super.onStart();
 // If the TreeItem is currently closed, we need to make it visible before
 // we can get its height.
 if (opening) {
  UIObject.setVisible(curItem.childSpanElem, true);
  scrollHeight = curItem.childSpanElem.getScrollHeight();
 }
}

代码示例来源：origin: com.google.gwt/gwt-servlet

public int getMaximumVerticalScrollPosition() {
 return getScrollableElement().getScrollHeight() - getElement().getClientHeight();
}
