{{ APIRef("DOM") }}

+ +

Node.children 唯讀屬性會回傳一個 Node 之子{{domxref("Element","元素")}}的動態（live）{{domxref("HTMLCollection")}}。

+ +

語法

+ +
var children = node.children;
+ +

children 是一個 {{ domxref("HTMLCollection") }}，為一個有順序性、由 node 中的 DOM 子元素所組成的集合。假如沒有子元素，則 children 內便不包含任何元素，且 length 為 0。

+ +

範例

+ +
var foo = document.getElementById('foo');
+for (var i = 0; i < foo.children.length; i++) {
+    console.log(foo.children[i].tagName);
+}
+
+ +

Polyfill

+ +
// Overwrites native 'children' prototype.
+// Adds Document & DocumentFragment support for IE9 & Safari.
+// Returns array instead of HTMLCollection.
+;(function(constructor) {
+    if (constructor &&
+        constructor.prototype &&
+        constructor.prototype.children == null) {
+        Object.defineProperty(constructor.prototype, 'children', {
+            get: function() {
+                var i = 0, node, nodes = this.childNodes, children = [];
+                while (node = nodes[i++]) {
+                    if (node.nodeType === 1) {
+                        children.push(node);
+                    }
+                }
+                return children;
+            }
+        });
+    }
+})(window.Node || window.Element);
