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。
