Click event
<body> <h2>javascript 事件</h2> <ul> <li>aaaa</li> <li>aaaa111</li> <li>aaaa222</li> <li>aaaa3333</li> <li>aaaa444</li> </ul> <script type="text/javascript"> //获取所有li的节点 var list = document.getElementsByTagName("li"); //给每个li绑定事件 for(var i = 0;i<list.length;i++){ list[i].onclick = function(){ //弹出对应的li节点里面的内容 alert(this.innerHTML); //将节点的颜色变成红色 this.style.color = "red"; } } </script> </body>
Double-click event
<body> <h2>javascript 事件</h2> <ul> <li>aaaa</li> <li>aaaa111</li> <li>aaaa222</li> <li>aaaa3333</li> <li>aaaa444</li> </ul> <script type="text/javascript"> //获取所有li的节点 var list = document.getElementsByTagName("li"); //给每个li绑定事件 for(var i = 0;i<list.length;i++){ list[i].ondblclick = function(){ //弹出对应的li节点里面的内容 alert(this.innerHTML); this.style.color = "red"; } } </script> </body>
PS: Let’s take a look at the js loop to bind click events with different parameters to li
<li>1</li> <li>2</li> <li>3</li> <li>4</li> </ul> <script type="text/javascript"> var li=document.getElementsByTagName_r("li"); for(var i=0;i<li.length;i++){ (function(x){ li[x].onclick=function(){alert(x);} })(i); } </script>
The value that pops up for each li is different
The above is a small The JavaScript I introduced to you binds click events to each li node. I hope it will be helpful to everyone
