The site like this:
`--main.html
`--dialog.html
`--folder
`--iframe.html
and the code is here:
main.html:
<html>
<head>
<script type="text/javascript">
function testframe() {
var doc = document.getElementById("frame").contentWindow;
doc.show();
}
</script>
</head>
<body>
<iframe src="folder/iframe.html" id="frame"></iframe>
<br/>
<button onclick="testframe()">test</button>
</body>
</html>
dialog.html:
<html>
<head>
</head>
<body>
This is modal dialog!
</body>
</html>
iframe.html:
<html>
<head>
<script type="text/javascript">
function show() {
showModalDialog('../dialog.html');
}
</script>
</head>
<body>
this is ifram
<br />
<button onclick="show()">show dialog</button>
</body>
</html>
When I click the show dialog button in the ifram,it show the modal dialog correctly.
When I click the test button outside the ifram ,it show the modal dialog incorrectly.
How can I fix this when I click the test button outside the ifram to show the correct page in the dilog?
iframeDomElement.contentWindow.setTimeout(function() {
iframeDomElement.contentWindow.childFunc();
}, 0);
This hack will make the relative path relative to the child window. Works in firefox and chrome，but not in safari.

I have written a JavaScript alert message code it displays the alert message first in both codes 1 and 2 before Html content. What should I do to run the HTML content first and then a javascript code?
Code 1
<!DOCTYPE html>
<html>
<head>
<title>Hello, World !</title>
</head>
<body>
<h1>I am learning JavaScript.</h1>
<div id="Content">
<p>This is a paragraph tag. Here the content of html.</p>
</div>
<script src="text.js"></script>
</body>
</html>
Code 2
<!DOCTYPE html>
<html>
<head>
<title>Hello, World !</title>
</head>
<body>
<h1>I am learning JavaScript.</h1>
<div id="Content">
<p>This is a paragraph tag. Here the content of html.</p>
</div>
<script>
alert(" This is alert message.");
</script>
</body>
</html>
There is a load event, which will fire AFTER the page is loaded. You can listen to the event:
window.addEventListener('load', function() {
console.log('All assets are loaded');
alert ("This is an alert MSG");
})
You can use setTimeout() for this
<html>
<head>
<title>Hello, World !</title>
</head>
<body>
<h1>I am learning JavaScript.</h1>
<div id="Content">
<p>This is a paragraph tag. Here the content of html.</p>
</div>
<script>
setTimeout(()=>{
alert(" This is alert message.")
},2000)
</script>
</body>
</html>
You can use window.onload function. This function called after body load.
<!DOCTYPE html>
<html>
<head>
<title>Hello, World !</title>
</head>
<body>
<h1>I am learning JavaScript.</h1>
<div id="Content">
<p>This is a paragraph tag. Here the content of html.</p>
</div>
<script>
window.onload = function () {
alert(" This is alert message.");
}
</script>
</body>
</html>
In your first code just put defer attribute as below
<script defer src="text.js"></script>
A script that will be downloaded in parallel to parsing the page, and executed after the page has finished parsing
for more detail refer to the URL
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script
create your Script like below
<script type = "text/javascript">
function displayalert() {
alert ("This is an alert MSG");
}
</script>
add this code in your body(this is a button)
<input type = "button" value = "Click me" onclick = "displayalert();" />
when you click on this button you will see the alert
We are using the onclick attribute and call the displayalert() function where the alert() is defined.

I'm new to Javascript so please bear with me.
I have code which refreshes the div of the parent window when the child window closes. The problem is when content of the div refreshes it creates a duplicate, and I don't know why. My code is below.
Inside the head tag of the parent I'm doing this:
<html>
<head>
<script language="javascript" type="text/javascript">
function ParentWindowFunction()
{
$(".mydiv").load("Welcome.jsp");
return false;
}
</script>
</head>
<body>
<div class="mydiv">
<img src="<s:property value="#session.img"/>" id="img" width="200" height="150" />
</div>
</body>
</html>
Inside child window's head tag I have:
<html>
<head>
<script type="text/javascript">
function refreshAndClose()
{
window.opener.ParentWindowFunction();
window.close();
}
</script>
</head>
<body onbeforeunload="refreshAndClose();">
...
</body>
</html>
i found solution for my problem instead of refreshing div i am reloading entire page like this
<script>
function winopen()
{
chatterinfo = window.open('fileupload.jsp',"chatterwin","scrollbars=no,resizable=yes, width=400, height=300, location=no, toolbar=no, status=no");
chatterinfo.focus();
}
</script>
<script language="javascript" type="text/javascript">
function ParentWindowFunction()
{
window.location="Login.action?uname=${uname}&&pass=${pass}";
}
</script>
</head>
<body>
<div class="mydiv">
<img src="<s:property value="#session.img"/>" id="img" width="200" height="150" />
</div>
</body>
</html>
Inside child window's head tag I have:
<html>
<head>
<script type="text/javascript">
function refreshAndClose()
{
window.opener.ParentWindowFunction();
window.close();
}
</script>
</head>
<body >
<input type=button onclick="refreshAndClose();" />
</body>
</html>
I am using an iFrame in my application. Let me give an example here.
I have main page as
<html>
<head>
<script src='jquery.js'></script>
<script>
function TestFunction()
{
var FirstName = $("#first_name").val();
alert(FirstName);
}
</script>
<head>
<body>
Enter First Name: <input type='text' size='20' id='first_name'><br />
<input type='button' value='Cilck' onclick='TestFunction();'><br />
<iframe id='test_iframe' src='test_iframe.htm' height='200' width='200'>
</iframe>
</body>
</html>
...and this works fine with alerting whatever is entered in textbox
But is it possible to invoke the same function in iframe that will alert the value present in textbox of the parent page?
Suppose test_iframe.htm code is like this
<html>
<head>
<script src='jquery.js'></script>
<script>
function IframeFunction()
{
TestFunction(); // I know this wont work.. just an example
}
</script>
<head>
<body>
<input type='button' value='Click' onclick='IframeFunction();'>
</body>
</html>
Can this be done ?
I believe this can be done with 'parent'
function IframeFunction()
{
parent.TestFunction();
}
<html>
<head>
<script src='jquery.js'></script>
<script>
function IframeFunction()
{
parent.TestFunction(); // or top.TestFunction()
}
</script>
<head>
<body>
<input type='button' value='Click' onclick='IframeFunction();'>
</body>
</html>
<a onclick="parent.abc();" href="#" >Call Me </a>
See Window.Parent
Returns a reference to the parent of the current window or subframe.
If a window does not have a parent, its parent property is a reference to itself.
When a window is loaded in an , , or , its parent is the window with the element embedding the window.

I have a "print" button on index.html. What code do I need to print the print.html file? I mean, when I press the button from index.html, print the page print.html.
function closePrint () {
document.body.removeChild(this.__container__);
}
function setPrint () {
this.contentWindow.__container__ = this;
this.contentWindow.onbeforeunload = closePrint;
this.contentWindow.onafterprint = closePrint;
this.contentWindow.focus(); // Required for IE
this.contentWindow.print();
}
function printPage (sURL) {
var oHiddFrame = document.createElement("iframe");
oHiddFrame.onload = setPrint;
oHiddFrame.style.visibility = "hidden";
oHiddFrame.style.position = "fixed";
oHiddFrame.style.right = "0";
oHiddFrame.style.bottom = "0";
oHiddFrame.src = sURL;
document.body.appendChild(oHiddFrame);
}
Then use
onclick="printPage('print_url');"
I think you're looking for window.print()
Update
Just noticed you've specified file names in there and that you want to print print.html when a button on index.html is clicked. There's no built-in way to do this (in the sense that you can't pass any arguments to window.print() indicating the document to print). What you could do is load the document to print into an iframe or open a new window and on load, invoke window.print() on that container.
Here are some forum posts and web pages that talk about the same thing:
http://www.highdots.com/forums/javascript/printing-another-web-file-present-274201.html
http://www.webmasterworld.com/javascript/3524974.htm
http://www.felgall.com/jstip29.htm
Update 2
Here's some quick-and-dirty code - note that this will only work if both your pages are in the same domain. Additionally, Firefox seems to fire the load event for an empty iframe also - so the print dialog will be displayed immediately on load, even when no src value was set for the iframe.
index.html
<html>
<head>
<title>Index</title>
<script src="http://code.jquery.com/jquery-1.4.3.min.js"></script>
<script>
$(document).ready(function(){
$('#loaderFrame').load(function(){
var w = (this.contentWindow || this.contentDocument.defaultView);
w.print();
});
$('#printerButton').click(function(){
$('#loaderFrame').attr('src', 'print.html');
});
});
</script>
<style>
#loaderFrame{
visibility: hidden;
height: 1px;
width: 1px;
}
</style>
</head>
<body>
<input type="button" id="printerButton" name="print" value="Print It" />
<iframe id="loaderFrame" ></iframe>
</body>
</html>
print.html
<html>
<head>
<title>To Print</title>
</head>
<body>
Lorem Ipsum - this is print.html

You can use the JQuery printPage plugin (https://github.com/posabsolute/jQuery-printPage-plugin). This plugin works fine and you can simply print an external html page.
Example:
<html>
<head>
<title>Index</title>
<script src="http://www.position-absolute.com/creation/print/jquery.min.js" type="text/javascript"></script>
<script src="http://www.position-absolute.com/creation/print/jquery.printPage.js" type="text/javascript"></script>
<script>
$(document).ready(function() {
$(".btnPrint").printPage();
});
</script>
</head>
<body>
<input type="button" id="printerButton" name="print" value="Print It" />
<p><a class="btnPrint" href='iframe.html'>Print!</a></p>
</body>
</html>
