How to Show Pop Up Window Using JavaScript

How to Show Pop Up Window Using JavaScript


You can show pop up window By using JavaScript window.open() method which loads specified URL into a new or existing window and returns the window object that represents that window.

The window.open() method takes four optional arguments which are URL of the window, Window name, attributes of window, the boolean value to replace or not the current window.

Syntax: window.open("windowname.html", "New Window", "width=width in pixel, height=height in pixel, status=yes or no, resizable=yes or no");

The first argument of window.open() method allows to display given URL in the new window. If the argument is omitted, the special blank-page URL:about:blank is used.

The second argument of window.open() method is a string which specifies a window name. If the argument is omitted, the special name "_blank" is used which opens a new, unnamed window.

The third optional argument of window.open() method is a comma-separated list of size and features attributes for the new window to be opened. If you omit this argument, the new window is given a default size and has a full set of UI components: a menu bar, status bar, toolbar etc.

The fourth optional argument of window.open() is useful only when the second argument names an existing window. It is a boolean value that indicates whether the URL specified as the first argument should replace the current entry in the windows browsing history: written true, or create a new entry in the windows browsing history: written false. And omitting the argument is same as written false.

Here is an example to open a small but resizable browser window with a status bar but no menu bar, tool-bar, or location bar.

window.open("new_window.html", "New Window", "width=400, 
height=350, status=yes, resizable=yes");

Here status bar is showing using status=yes and the window is resizable  using resizable=yes, if you dont want to show status bar, you can use status=no and want the fixed window, can use resizable=no in the argument.

To open a new pop up window on onclick event of button, you can use the following code.

<input type=button name="open" value="Open window"
onclick="window.open(http://www.siteforinfotech.com/p/about-us.html
,new window, width=400, height=350, status=yes, resizable=yes);">

To open a new pop up window on <a> href link, you can use the following code.

<a href="javascript:void window.open
(http://www.siteforinfotech.com/p/about-us.html, new window,
width=400, height=350, status=yes, resizable=yes);
">Open Pop Up window</a>

Preview:

Open Pop Up window

The return value of the window.open() method is the window object that represents the named or newly created window. You can use this window object in you JavaScript code to refer to the new window and to specify the properties on it as given below.

var w=window.open();
w.alert("You are going to visit:http://www.siteforinfotech.com");
w.location="http://www.siteforinfotech.com";


Here you can specify other properties like width, height, status, resizable given above. And you can assign variable w for any windows event or on any event trigger using JavaScript.

"Pop Up" and "Pop Under" advertisements are made by using this method window.open() while you browse the web. JavaScript codes that tries to open a pop up window when the browser first loads, browsers blocked them. So the advertisements are made to run pop up windows only in response to a user action such as clicking on button and clicking on link.

How to Show Pop Up Boxes Using JavaScript

How to Show Pop Up Boxes Using JavaScript


Using JavaScript you can create three kinds of pop-up boxes, Alert box, Confirm box and prompt box.

Alert Box


An alert box is used if you want to make sure information comes through to the user. When an alert box pops up, the user will have to click on "OK" to processed.

Syntax:

alert("Alert Text")

Example:

<html>
<head>
<script type="text/javascript">
function display_alert()
{
alert("This is an alert box!")
}
</script>
</head>
<body>
<input type="button" onclick="display_alert()" value="Display alert box"/>
</body>
</html>

Preview:




 Conform box


A conform box is used if you want the user to verify or accept something. When a conform box pops up, the user will have to click either "OK" or "Cancel" to processed. If the user clicks "OK" the box returns true. If the user clicks "Cancel", the box returns false.

Syntax:

confirm{"Conform Text")

Example:

<html>
<head>
<script type="text/javascript">
function display_conform(){

r=confirm("Press a button");
if (r===true)
{
alert("You pressed OK!");
}
else
alert("You pressed Cancel");
}
</script>
<body>
<input type="button" onclick="display_conform()" value="Display a confirm box"/>
</body>
</html>

Preview:



 Prompt Box


A prompt box is used if you want the user to input a value before entering a page. When a prompt box pops up, the user will have to click "OK" or "Cancel" to processed entering in input value.
If the use clicks "OK" the box returns the input value. If the user clicks "Cancel" the box returns null.

Syntax:

prompt{"sometext", "defaultvalue"}

Example:

<html>
<head>
<script type="text/javascript">
function display_prompt(){
name=prompt("Please enter your name", "Your Name");
if ((name!=null) && name!=" ")
{
alert("Hello "+name+"! How are you today?");
}
}
</script>
</head>
<input type="button"onclick="display_prompt()" value="Display a prompt box"/>
</body>
</html>

How to Create Show Hide Effect in Image SlideShow Using JQuery

How to Create Show Hide Effect in Image SlideShow Using JQuery


The fadeOut() effect presented on the post "How to create Fade Effect in Image Slideshow using JQuery" which I have already posted, makes elements invisible but retains space for them in the document layout.

The hide() method, by contrast, removes the elements from the layouts as if the CSS display property was set to none. When invoked with no arguments, hide() and show() simply hide or show the selected elements immediately. With a duration argument, however, they animate the hiding or showing process. hide() shrinks an elements width and height to 0 at the same time that it reduces the elements opacity to 0. show() reverses the process.

toggle() changes the visibility state of the elements, it is invoked on, if they are hidden, it calls show(), and it they are visible, it calls hide(). As with show() and hide(), you must pass a toggle() to get an animated effect. Passing true to toggle() is the same as calling show() with no arguments. Note also that if you pass two or more function arguments to toggle() it registers event handlers.

Here is an example that invokes methods for show/hide effect animation. The first image has show() effect animation, second image has hide() effect animation and the third animation has toggle() effect animation.

$("#img1").show(2000);
$("#img2").hide(3000);
$("#img3").toggle(1000);

Here are some examples to show show(), hide() and toggle() effects using jQuery.

Example of show() Effect 


<script>
$(document).ready(function(){
$(#btn1).click(function () {
$("#img1").show(2000);
});
});
</script>

<input type=button id="btn1" value="Start Show"/>
<img id="img1" src="img1.jpg">



Example of hide() Effect


<script>
$(document).ready(function(){
$(#btn2).click(function () {
$("#img2").hide(3000);
});
});
</script>

<input type=button id="btn2" value="Start Hide"/>
<img id="img2" src="img2.jpg">



Example of toggle() Effect 


<script>
$(document).ready(function(){
$(#btn3).click(function () {
$("#img3").toggle(1000);
});
});
</script>






<input type=button id="btn3" value="Start Toggle"/>
<img id="img3" src="img3.jpg">


Full jQuery code for Show/Hide effect image animation


<script 

src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
</script>

<style>
.show_hide
{
box-shadow:1px 1px 5px 2px #6DC83C;
position:relative;
width:448px;
height: 336px;
border-radius:19px;
}

.show_hide img
{
border-radius:19px;
position:absolute;
left:0;
top:0;
}

</style>

<script>
$(function(){
$(.show_hide img:gt(0)).hide();
setInterval(function(){$(.show_hide :first-child).hide(3000).next(img).show(3000).end

().appendTo(.show_hide);}, 6000);
});
</script>

<div class="show_hide">
<img src="img1.JPG" />
<img src="img2.JPG" />
<img src="img3.JPG" />
</div>
