dojo/query返回的是匹配查询结果的所有节点构成的数组；这个数组实际上是一个特殊的数组对象称为dojo/NodeList， 该数组对象内建了一系列可以方便操作其中节点的方法。
- <!DOCTYPE html>
- <html>
- <head lang="en">
- <Meta charset="UTF-8">
- <title>NodeList</title>
- <script src="dojo/dojo.js" data-dojo-config="async: true"></script>
- <script>
- require(["dojo/query","dojo/domReady!"],function(query){
- query("li.fresh").on("click",function(){
- alert("I love fresh " + this.innerHTML);
- });
- });
- </script>
- </head>
- <body>
- <ul>
- <li class="fresh">Apples</li>
- <li class="fresh">Persimmons</li>
- <li class="fresh">Grapes</li>
- <li class="fresh">Fresh Figs</li>
- <li class="dried">Dates</li>
- <li class="dried">Raisins</li>
- <li class="dried">Prunes</li>
- <li class="fresh dried">Apricots</li>
- <li class="fresh">Peaches</li>
- <li class="fresh">Bananas</li>
- <li class="fresh">Cherries</li>
- </ul>
- </body>
- </html>
等效于：
- <script>
- require(["dojo/query",function(e){
- alert("I love fresh " + e.target.innerHTML);
- });
- });
- </script>
等效于：
- <script>
- require(["dojo/query","dojo/on",function(query,on){
- on(query("li.fresh"),"click",function(e){
- alert("I love fresh " + e.target.innerHTML);
- });
- });
- </script>
备注：dojo/NodeList对象与DOM NodeList对象是不相同的。
