JavaScript questions about refreshing the parent page after Open.window child page execution _javascript tips

The example of this article analyzes JavaScript's method of refreshing the parent page after the execution of the Open.window child page. Share to everyone for your reference. The specific analysis is as follows:

Main Page:

<input id= "btnadd" type= button "onclick=" Openwin (); "value=" Add "/>"

The following code is available in JS:

function Openwin () {
window.open (' addinfo.jsp ', ' _blank ', '
width=300,height=400,top=200,left=400 ');
}
  Defines the callback method for callback
  function callback () {
refreshwin ();
}
Refreshes the current page
function Refreshwin () {
//calls the Refresh page method, where Refreshsocket the corresponding method for refreshing the page
//That is, if the page has a refresh button,
/ Then click the button to submit the class name is here the class name
var url = ' Refreshsocket ';
window.location.href = URL;
}

The following code is available on the addinfo.jsp page:

<form name= "form" action= "Addsocket" method= "get" > <input id= "onsub" button "type=" onclick=
(); "Value= OK" >
</form>

function Formsubmit () {
this.form.submit ();
Submit action to Addsocket class
window.opener.callback ();
When the above execution is complete, call the callback method that opens the page,
//Here is the callback method Window.close () that calls the master page
();//The current page closes
}

Main Page mainpage.jsp:

window.location.href = Deletesocket

Deletesocket class Page:

After you have written this sentence, you can jump directly to the main page and refresh the main face.

Out.print ("<script type= ' text/javascript ' >location.href= ' mainpage.jsp ' </script>");
