<!DOCTYPE html> <html> <head> <script src="/jquery/jquery-1.11.1.min.js"> </script> <script> $(document).ready(function(){ $("ul li:eq(0)").appendTo("ul"); }); </script> </head> <body> <ul> <li title="li1">1</li> <li title="li2">2</li> <li title="li3">3</li> <li title="li4">4</li> <li title="li5">5</li> </ul> </body> </html>
<!DOCTYPE html> <html> <head> <script src="/jquery/jquery-1.11.1.min.js"> </script> <script> $(document).ready(function(){ $("ul li:eq(0)").appendTo("ul");//move li method1 //move method2: var removeLi = $("ul li:eq(0)").remove();//delete li removeLi.appendTo($("ul"));//add removed li }); </script> </head> <body> <ul> <li title="li1">1</li> <li title="li2">2</li> <li title="li3">3</li> <li title="li4">4</li> <li title="li5">5</li> </ul> </body> </html>
运行结果为:
//remove all li $("ul li").remove();
//remove some $("ul li").remove("li[title!=‘li2‘]");
//empty children $("ul").empty();
会删除<ul>中的所有子节点.
//empty content $("ul li:eq(3)").empty();
会得到这样的效果:
