I want to change the text of the status window when the mouse is over a link. My link's name is: Hipervinculo.
Then, when the mouse is out of the link it should appear a different text.
This is my html until now, but it doesn't work.
Can someone explain me how to do it?
Thank you so much!
<html>
<head>
<meta charset="UTF-8">
<title>Práctica 4</title>
<script type="text/javascript">
function info(txt){
window.status="txt";
}
function info2(txt){
window.status= "txt"
}
</script>
</head>
<body>
Hipervínculo
</body>
</html>
window.status has been disabled in most (if not all) browsers for security reasons (it was possible to fake a different location for links that way).

I have a question we must have seen many a time that when we are about to close the window and Just hover mouse over the cross on Browser Tab, a pop up appears asking for us to subscribe or highlighting some coupon. This Functionality is based on which feature of the browser, does it exploits some PHP code or some artificial intelligence.
It is run on client-side as everything that interact with user interface.
The example bellow shows how to do this with pure javascript (not tested with all browsers, but works well with Chrome)
<!DOCTYPE html>
<html>
<head>
<title>Page exit example</title>
<script type="text/javascript">
var showMessage = true;
window.onmouseout = function(){
if(showMessage){
showMessage = false;
document.getElementsByTagName('body')[0].innerHTML = "Dont leave yet!";
}
};
</script>
</head>
<body>
<h1>Hello world</h1>
</body>
</html>
In Javascript, I want to open my window.html file in a popup window. But it doesn't display any text. Just a blank page.
This is index.html:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css" />
<script language="javascript">
var newwindow;
function popit(url){
newwindow = window.open(
url, '', "status=yes, height=500; width=500; resizeable=0");
}
</script>
</head>
<body>
CLICK ME!
</body>
</html>
window.html:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<p>SAMPLE TEXT</p>
</body>
</html>
Why doesn't it display any text?
javascript:popit(window.html);
Replace with:
javascript:popit('window.html');
Your click handler code is syntactically incorrect:
CLICK ME!
Always, always have your developer console open to check for JavaScript errors! (edit — actually in this case there wouldn't have been an error; window.html would resolve to undefined probably! Still, keep the console open :-)
Also note that I used an "onclick" attribute instead of "href".
A GOOD working code with NO crashes.
Simple and what makes this code better is that you can use it in a JavaScript file separately and have it fairing to more then one file with the same popup size even though its different pages on popups.
Javascript
// Popup window code
function MyPopUp(url) {
popupWindow = window.open(
url,'popUpWindow','height=454,width=580,left=0,top=200,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no,status=yes')
}
HTML
My PopUp
NOTE: You can also use this as onload in body for example <body onload="JavaScript:MyPopUp('MyDirectory/Page.html');"> and it will aslo work on onmouseover and others... though I do not advise this unless you want to piss off the clients visiting your page.
I'am developing a web-application that allows to select parts of an html document and put some kind of annotation on it.
To get hold of the selected text I use window.getSelection() which works pretty fine in IE9, FF, and Safari.
However I run into trouble when using the same page on my IPad 2:
If I just select a word by tapping it for a sec, window.getSelection() returns the proper selection.
If I create a text range ( as discribed here http://blog.laptopmag.com/how-to-select-copy-and-paste-text-on-the-ipad ) always return "null".
I've already examined the window, document and related event objects - but without success...
Any help would be really appreciated!
Edit: Just a small example. Select a text and press the button. On Safari (PC) the function prints the selected value...
<html>
<body>
<script>
function a()
{
alert(window.getSelection());
}
</script>
Hello World! <input type="button" onclick="a();"
</body>
</html>
Okay finally I've solved the problem: As Tim assumed the click events causes to selection to collapse. I consider this as rather strange behavior as on regular Safari this does not happen.
However, the solution is not to use the click event. Instead of I'm using "vlick" provided by the jquery mobile.
Full working example:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.min.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.min.js"></script>
</head>
<body>
Hello World! <input type="button" id="button1" />
<script>
function a()
{
alert(window.getSelection());
}
$("#button1").bind("vclick",a);
</script>
</body>
</html>
I'm not sure if this is even possible.
I've got the following code;
<iframe src="http://www.domain.com/content.html" width="200" height="50"></iframe>
Now, I would have assumed that would've hyper-linked the entire iFrame area, however it only hyperlinks the border.
Is it possible to hyperlink the entire iframe area?
no, that's not valid. you can't even reliably get a click event off of the element containing the iframe.
e.g.,
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#bob').click(function(e){
alert('hi');
});
});
</script>
</head>
<body>
<div id="bob" style="padding:100px;background:red;"><iframe src="http://www.google.com"></iframe></div>
</body>
</html>
notice that if you click the iframe, no alert fires - but if you click anywhere else (in red), it will. if this were otherwise, there'd be abuse...
What actually do you mean by "hyperlink the iframe"?
You could try to use an onclick event for the iframe, or position a div with an onclick and transparent background above the iframe. Another possibility is to set the a to display: block and position it above the iframe.
*Update: Ultimately I've decided that accomplishing exactly what I want here isn't possible due to the issues it poses to security. Kalle's answer below gives a solution that is closest to what I want to accomplish.
In order to solve my problem I've created scripts on both pages and will use a sort of push notification that is routed through the server in order for them to communicate.
Thanks for the help!! *
I have two pages. Both windows already exist independently. Page two has a function declared in JS.
I would like to be able to call the function in window two by clicking a link in window one.
Page 1:
<html>
<head>
<title>This is a title!</title>
</head>
<body style="background: lightblue">
Click Me!
</body>
Page 2:
<html>
<head>
<META HTTP-EQUIV="Window-target" CONTENT="my_target" />
<title>This is a title!</title>
<script type=text/javascript>
function clicked() {
alert('test');
}
</script>
</head>
<body style="background: lightblue">
</body>
Since it is on the same domain you can get this to work but would have to change the way you were doing it a little.
First off you would have to open it in a popup using this syntax rather than a new tab:
newwindow=window.open(url,'name','height=200,width=150');
and then you could simply call newwindow.clicked() after the popup is called.
update
just did a quick test and this will open it in a new tab. (sorry its been a while since I used the open function.
newwindow=window.open(url,'name');
Just noticed also that you should wait for the popup to load. So in my Example it would look a little something like this (with jQuery):
var newwindow = window.open('http://www.tylerbiscoe.com/vb/new.html');
$(newwindow).load(function(){
newwindow.clicked();
});
Ok, brand new answer. I hope this is what you were thinking. This is however, when you open page 2 from page 1.. So basically, page 1 would know who page 2 is..
Online example: http://kopli.pri.ee/stackoverflow/6832271.php
Page 1
<html>
<head>
<title>Page 1</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<style>
.ajaxlink {color: blue; cursor: pointer; border-bottom: 1px dotted blue;}
</style>
</head>
<body>
<span id="open_page_2" class="ajaxlink">Open new window</span>
<br>
<br>
Click Me!
<script>
$('#open_page_2').click(function(){
child = window.open('test2.php','page_2','width=600,height=600');
});
$('a[target=my_target]').click(function () {
child.SecondPageFunction();
return false;
});
</script>
</body>
</html>
Page 2
<html>
<head>
<title>Page 2</title>
</head>
<body>
<h1>Your seeing page 2!</h1>
<script>
function SecondPageFunction () {
alert('Second page action got triggered!');
}
</script>
</body>
</html>
The script must be a part of the page you're opening in the new window. You're absolutely correct about it being a security flaw if it was elsewise allowed.
You could add some query string argument that could be picked up onload by javascript in the page you are opening and call your function if the query string arg is present.
