返回值

An integer value representing the type of the result, as defined by the type constants .

常量

Result Type Defined Constant	值	描述
ANY_TYPE	0	A result set containing whatever type naturally results from evaluation of the expression. Note that if the result is a node-set then UNORDERED_NODE_ITERATOR_TYPE is always the resulting type.
NUMBER_TYPE	1	A result containing a single number. This is useful for example, in an XPath expression using the count() 函数。
STRING_TYPE	2	A result containing a single string.
BOOLEAN_TYPE	3	A result containing a single boolean value. This is useful for example, in an XPath expression using the not() 函数。
UNORDERED_NODE_ITERATOR_TYPE	4	A result node-set containing all the nodes matching the expression. The nodes may not necessarily be in the same order that they appear in the document.
ORDERED_NODE_ITERATOR_TYPE	5	A result node-set containing all the nodes matching the expression. The nodes in the result set are in the same order that they appear in the document.
UNORDERED_NODE_SNAPSHOT_TYPE	6	A result node-set containing snapshots of all the nodes matching the expression. The nodes may not necessarily be in the same order that they appear in the document.
ORDERED_NODE_SNAPSHOT_TYPE	7	A result node-set containing snapshots of all the nodes matching the expression. The nodes in the result set are in the same order that they appear in the document.
ANY_UNORDERED_NODE_TYPE	8	A result node-set containing any single node that matches the expression. The node is not necessarily the first node in the document that matches the expression.
FIRST_ORDERED_NODE_TYPE	9	A result node-set containing the first node in the document that matches the expression.

范例

The following example shows the use of the resultType 特性。

HTML

<div>XPath example</div>
<div>Is XPath result a node set: <output></output></div>
					

JavaScript

var xpath = "//div";
var result = document.evaluate(xpath, document, null, XPathResult.ANY_TYPE, null);
document.querySelector("output").textContent =
  result.resultType >= XPathResult.UNORDERED_NODE_ITERATOR_TYPE &&
  result.resultType <= XPathResult.FIRST_ORDERED_NODE_TYPE;
