html mechanism
Look at the code<html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title></title> <script type="text/javascript" src="script/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function () { $("#add").append("<input id='test' type='text' value=''/>"); }); function AddValue() { $("#test").val("测试值"); } </script></head><body> <form id="form1" runat="server"> <div id="add"> <input type="submit" value="测试" onclick="AddValue();"/> </div> </form></body></html> Why click the test button. After setting the value of the text box, it disappears immediately. If you add return false; after onclick.
Will the page refresh when you click on the input control?
Reply to discussion (solution)
Because the button you click is the submit button, it triggers the submission of the form, which means re-sending a request to this page (refresh the page) /post/get), you can change it to type="button", and after your function is processed, trigger submit()
