This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the 兼容性表格 at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

NodeIterator.expandEntityReferences 只读特性返回 布尔 flag indicating whether or not the children of entity reference nodes are visible to the NodeIterator .

If this value is false , the children of entity reference nodes (as well as all of their descendants) are rejected. This takes precedence over the value of the NodeIterator.whatToShow method and the associated filter.

句法

expand = nodeIterator.expandEntityReferences;

范例

var nodeIterator = document.createNodeIterator(
    document.body,
    NodeFilter.SHOW_ELEMENT,
    { acceptNode: function(node) { return NodeFilter.FILTER_ACCEPT; } },
    false
);
expand = nodeIterator.expandEntityReferences;
