I know this has been mentioned multiple times, but I can't find exactly what I'm looking for.
Index.html code.
<html>
<head>
<meta charset="utf-8">
<title>myPage</title>
<script src="libs/h5.js"></script>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
</head>
<body>
<div id="content" width="1025" height="670">
<iframe id="homePage" src="pages/homepage.html" width="1025" height="670" seamless></iframe>
</div>
</body>
</html>
h5.js code
function setTextHidden()
{
<------------ **How do I call the hideText function inside the iframe from the parent?**
}
js code for homepage.html in iframe
function hideText()
{
console.log("hideText");
}
You can use window.frames property to access the window object of your iFrame, from which you can call hideText:
function setTextHidden() {
window.frames[0].hideText(); // assuming this is the first iframe on your page
}

I tried to create two buttons, so that when I click on each- I will get a pop up small window, with a content that it will get while onloading.
This is the code:
index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script type="text/javascript" src="script.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
</head>
<body ng-app="myApp">
<p ng-controller="ctrl">
<span ng-repeat="x in items">
<button ng-click="parentFunc(x.fieldOne,x.fieldTwo)">{{x.fieldOne}}</button>
<br><br>
</span>
</p>
<script>items();</script>
</body>
</html>
script.js:
var title, content;
function items(){
angular.module('myApp', []).controller('ctrl', function($scope) {
$scope.items = [
{fieldOne:"field1", fieldTwo:"field1 content"},
{fieldOne:"field2", fieldTwo:"field2 content"}
];
$scope.parentFunc=function(titleTmp,contentTmp){
title=titleTmp;
content=contentTmp;
var OpenWindow = window.open('popUp.html','_blank','width=500, height=400');
return false;
}
});
}
function codeAddress() {
document.getElementById("title").innerHTML=title;
document.getElementById("content").innerHTML=content;
}
popUp.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script type="text/javascript" src="script.js"></script>
</head>
<body onload="codeAddress();">
<h1 id="title"></h1>
<div id="content"></div>
</body>
</html>
The new pop up window open as expected, but the h1 and div in it get undefined. I tried to debug it, and I saw that after the first two lines of parentFunc are executed, the global variables title and content get what I expect and they are not undefined. However, when the third line is executed and the new window get opened- the global variables are undefined.
Why the two global variables are undefined in the pop up window?
And how can I solve this?
Your method won't work : you are trying to reload the script.jsand then, the vars are reinitialized.
Add your vars in the URL :
var OpenWindow = window.open('popUp.html?title='+titleTmp+'&content='+contentTmp,'_blank','width=500, height=400');
Then, in your second page, read those parameters :
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script type="text/javascript">
function codeAddress(){
var title = GET_TITLE_FROM_PARAMETER;
var content = GET_CONTENT_FROM_PARAMETER;
document.getElementById("title").innerHTML=title;
document.getElementById("content").innerHTML=content;
}
</script>
</head>
<body onload="codeAddress();">
<h1 id="title"></h1>
<div id="content"></div>
</body>
</html>
And of course, remove codeAddress from the first page as it's useless.
FYI, to get the parameters values, please check this answer.
I just started to go further in my web development skills in my job and stucked with a little problem.
I have an iFrame (iframe.html), and in this iframe is a div styled as a green square.
I want to change the color of the Div outside the iframe with a button in my Parent (index.html) with an onClick Function.
I tried a few things, like calling a normal Function (document.getElementById and so on). But nothing really worked.
So I thought, that jquery might have some solutions and I'm stucked now in this code, but it doesn't work.
Can anyone help?
PS: this is not a cross-origin case. i got both html files in the same Directory.
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="css/index.css">
<script src="jquery-1.12.2.min.js"></script>
<title>buttonframetest</title>
<script type="text/javascript">
function Clickit() {
$(document).ready(function(){
$('iframe').contents().find('background-color').css('backgroundColor', 'white');
});
}
</script>
</head>
<body>
<iframe id="iframe" src="iframe.html" width="500px;" height="500px">
<p>iFrame nicht darstellbar in deinem Browser</p>
</iframe>
<br>
<button type='button' onClick="Clickit();">Klick</button>
<button type="button" onclick="redy">CHANGE</button>
<br>
<div class="ChangeColor"></div>
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="js/index.js"></script>
</body>
</html>
This can be done with the DOM iframe object's contentDocument property:
document.frames[0].contentDocument.getElementById('id here').style['background-color']=whatever;
Or, alternatively, with window.postMessage:
// this is in parent
document.frames[0].postMessage('red', '*');
// this is in frame
window.onmessage = function(x) {
if (x.origin == 'http://www.example.com') document.getElementById('id here').style['background-color'] = x.data;
}
Add this,
Update your jQuery CDN
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>
function clck(){
$(document).ready(function(){
$('iframe').css({
'background' : '#fff'
});
});
}
I have a problem that some link we show is separeted from the rest of the page itself, so the link showes up immediatly as you open the page but the page takes 2-3 seconds to load, I'm trying to delay the link (in this example it's google) so it will show up a few seconds after the page is loaded.
am I getting close?
<!DOCTYPE html>
<html>
<head>
<title>Delay export link</title>
<script type="text/javascript">
function myFunction() {
myVar = setTimeout(show(), 2000);
}
function show() {
document.getElementById("Link").style.display = "inline";
}
function exportSrc() {
var scrt_var = "www.google.com;
document.getElementById("Link").setAttribute("href",scrt_var);
}
</script>
</head>
<style>
#Link{display:none;}
</style>
<body window.onLoad="myFunction();">
<a id="Link" onclick="exportSrc();" target='_blank'>
<img src="http://i57.tinypic.com/mkw779.png">
</a>
</div>
</body>
</html>
You have a few errors in your page which is stopping this from working:
Usually the first thing to check when something is not working is the browser console (press F12) and looks for errors. This won't fix problems with logic but should put you in a good position to start debugging things.
You have a missing " syntax error in exportSrc - this will show in the browser console
The load attribute in the body is incorrect. You should just use onload="myFunction()"
Your setTimeout is calling show instead of referencing it. Remove the ()s.
Put the <style> tags inside the <head>
You have an extra </div> tag
This should work better:
<!DOCTYPE html>
<html>
<head>
<title>Delay export link</title>
<style>
#Link{display:none;}
</style>
<script type="text/javascript">
function myFunction() {
myVar = setTimeout(show, 2000);
}
function show() {
document.getElementById("Link").style.display = "inline";
}
function exportSrc() {
var scrt_var = "www.google.com";
document.getElementById("Link").setAttribute("href",scrt_var);
}
</script>
</head>
<body onload="myFunction();">
<a id="Link" onclick="exportSrc();" target='_blank'>
<img src="http://i57.tinypic.com/mkw779.png">
</a>
</body>
</html>
Try
<body onLoad="myFunction();">
Instead of window.onLoad
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 an Iframe.html file :
<body onload="alert('frame 1 loaded');">
<div> This is frame 1 content </div>
<a id="a1" href="Sample.html"> click</a>
</body>
Sample.html
<body>
<ul id="list1">
<li name="one">one</li>
<li name="two">two</li>
</ul>
And I calling the iframe form test.html file :
<script type="text/javascript" src="jquery-1.5.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var i=10;
$("#frame1").ready(function () {
$('#frame1').contents().find('#a1').click(function() {
alert("Hello");
$('#frame1').attr('src', $('#frame1').contents().find('#a1').attr("href"));
$('#frame1').load();
});
$('#frame1').contents().find('#a1').click();
</script>
</head>
<body onload="handleMainOnload();">
<!--iframe id="frame1" src="about:blank"/-->
<iframe id="frame1" src="iframe.html"/>
</body>
Now I tried using the content of URL loaded in iframe i.e. Sample.html in test.html as follows :
$('#frame1').contents().find('#list1 li[name=one]').click(function() {
alert(" Clicking list....");
});
$('#frame1').contents().find('#list1 li[name=one]').click();
But this doesn't work.. Can you please tell me From Test.html how to access Sample.html file content like(id,name,class etc.) which is loaded in iframe.html using JQuery.
Please help.
Thanks

To access any document inside an iframe included inside an HTML take for example the following page:
<html>
....
<body>
<iframe id='myFrame' name='myFrame' src='someUrl'>
</body>
</html>
You can access using the following script
myFrame.document.getElementById('elementID');
Make sure you provide a name (here: myFrame) that is used to access the frame itself.
The elementID is the id of any element inside the html/url loaded inside the iframe
<html>
<head>
<title>Main Frame 2 Title </title>
<script type="text/javascript" src="jquery-1.5.1.min.js"></script>
<script type="text/javascript">
------
------
alert("frame ready");
var $value1 = $frame.contents().find('#list1 li[name=one]').html() ;
alert("loaded + " + $value1);
$frame.contents().find('#list1 li[name=one]').click(function() {
alert("About + clicked");
});
$frame.contents().find('#list1 li[name=one]').click();
}); });
</script>
</head>
<body>
<iframe id="frame1" src="sample.html" />
This works fine, if i am giving iframe src=sample.html directly instead of redirecting using another file (i.e. src=iframe.html) and keeping Sample.html in same domain as parent file (test.html).
