JavaScript Popup Window method

This article summarizes the commonly used JavaScript pop-up window method, for everyone to compare the reference, hope to be helpful to everyone. The detailed methods are as follows:

1. Silently refresh the webpage:

We have found that some pages, when refreshed, will pop up a prompt window, the point "OK" will be refreshed.
And some pages will not prompt, do not pop up the prompt window, directly on the refresh.
If the page does not have a form,
The prompt window will not pop up
If the page has a form form,
A) <form method= "POST" ...>
A popup window will appear
b) <form method= "Get" ...>
does not eject

Refresh the parent window using a pop-up window with window.open ()

?

Modal window with Window.showdialog pop-up

Parameter passing:

(1). To pass a parameter to a dialog box, pass it through varguments. Type is not limited, for string types, the maximum is 4,096 characters. You can also pass objects, for example:
-------------------------------
Parent.htm page:

?

12345

<script>varobj = newObject();obj.name="jb51";window.showModalDialog("modal.htm",obj,"dialogWidth=200px;dialogHeight=100px");</script>

Modal.htm page:

?

1234	<script>varobj = window.dialogArgumentsalert("您传递的参数为："+ obj.name)</script>

(2) You can return information by Window.returnvalue to the window that opens the dialog box, or it can be an object. For example:

Parent.htm page Code:

?

12345678

<script>str =window.showModalDialog("modal.htm",,"dialogWidth=200px;dialogHeight=100px");alert(str);</script>modal.htm<script>window.returnValue="http://www.jb51.com";</script>

Example:

?

12345678

function ShowDialog(url) {  var iWidth=300; //窗口宽度  var iHeight=200;//窗口高度  var iTop=(window.screen.height-iHeight)/2;  var iLeft=(window.screen.width-iWidth)/2;  window.showModalDialog(url,window,"dialogHeight: "+iHeight+"px; dialogWidth: "+iWidth+"px;dialogTop: "+iTop+"; dialogLeft: "+iLeft+"; resizable: no; status: no;scroll:no"); }

Note the second argument here, window

4. Mode window data does not refresh (cache) problem

Add the following statement to the JSP page

?

12345

5. mode window, link popup new Window issue:

_blank, open the linked file in a new browser window.

_parent, loads the linked file into the parent frameset or parent window that contains the linked frame. If the frame containing the link is not nested, the linked file is loaded in a full-screen browser window, just like the _self parameter.

_self, open the linked document in the same frame or window. This parameter is the default value and is usually not specified.

_top, the linked document is opened in the current entire browser window, so all frames are deleted.

Add <a href= "a.html" target= "_blank" between

6. How to close the page without prompting:

function CloseWin(){  var ua = navigator.userAgent; var ie = navigator.appName=="Microsoft Internet Explorer"?true:false;  if(ie){ var IEversion = parseFloat(ua.substring(ua.indexOf("MSIE ")+5,ua.indexOf(";",ua.indexOf("MSIE "))));  if( IEversion< 5.5){  var str = ‘‘;  document.body.insertAdjacentHTML("beforeEnd", str);   document.all.noTipClose.Click();  } else {   window.opener =null; window.close();  } }else{ window.close() }}
