在本教程中,我们将看到jQuery after和InsertAdter方法。
两者都执行相同的任务,在每个选定的元素后插入文本或者html,但语法是完全不同的。
after()的语法:
$("selectors").after("element to be inserted") ; Example : $("div").after("");
InsertAfter()语法:
$("element to be inserted") .insertAfter("selectors"); Example: $("element to be inserted").insertAfter("div");
让我们通过示例来理解:
<!doctype> <html> <head> <title>Jquery after and insertAfter example example </title> <script src="http://code.jquery.com/jquery-2.2.3.min.js"></script> </head> <h2>Jquery after and insertAfter example example</h2> <style> .red{ border:3px dotted red; color:red; font-family: arial narrow; } .blue{ border:3px dotted red; color:blue; font-family: arial narrow; } </style> <script type="text/javascript"> $(document).ready(function(){ $("#afterButton").click(function(){ $("div").after("inserting using after"); }); $("#insertAfterButton").click(function(){ $("inserting using insertAfter").insertAfter("div"); }); $("#reset").click(function(){ location.reload(); }); }); </script> <body> <button id="afterButton">Using after</button> <button id="insertAfterButton">Using insertAfter</button> <button id="reset">Reset</button> <div> Hello world from theitroad!!!! </div> <div> Welcome to JQuery. </div> </body> </html>
