I have an iframe with src but I want to provide the link to src via javascript on click of the button. How do I pass the value?
EDIT: The webpage refreshes everytime I click on the button. It displays the webpage and then refreshes it to display again. How to avoid this?
<button type="button" onclick = "Open()">Click Me!</button>
<iframe id="iframe"
src="" //Provide link here
style="
z-index: 10;
display: None;
">
</iframe>
<script>
function Open() {
let myIframe = document.getElementById("iframe");
myIframe.style.display = 'block';
iframe.src = "www.mylink.com"
}
</script>
you're not referencing myIframe when setting src in the example, you need to do myIframe.src = 'https://www.mylink.com'

story: hide the iframe if the .php is deleted or similar. So i try to hide the div that contains the iframe. Website of customer A can iframe a video from my website (external-website). But if the video is deleted, it should hide the complete iframe (the div). The complete php will be deleted or renamed if the video is not available.
Hide the <div> if external file (i want to iframe)
is not available or named as .php?=123456 or has not a <div "id", whatever.
The inline style never changes.
I tried each of this above, i don`t get it working.
I can edit the external .php file (my website too).
I do not get the script to change the inline style whatever i try.
What i want to do, hide the div if "something".
<div id="hide-me">
<iframe src="https://www.external-website.com/subfolder/1250.php" style="background-color: white;border: 0;height: auto;text-align:center;width: auto;max-height: 100%;" scrolling="no"></iframe>
</div>
<script>
function yourFunctionName () {
var anyname = document.getElementById("hide-me").style.display;
if(document.getElementById("id-in-external-php").src == 'https://www.external-website.com/subfolder/1250.php'){
document.getElementById("hide-me").style.display="block";
} else {
document.getElementById("hide-me").style.display="none";
}
}
</script>
I asked a similar question here, but it did not give a solution
enter link description here
content of https://www.external-website.com/subfolder/1250.php :
<div id="id-in-external-php">this is content for the iframe</div>
This is how I ran your code again and it worked, so you can try it:
<div id="hide-me" style="display: none;">
<iframe style="display: none;" id="id-in-external-php" src="https://www.external-website.com/subfolder/1250.php" style="background-color: white;border: 0;height: auto;text-align:center;width: auto;max-height: 100%;" scrolling="no"></iframe>
</div>
<script>
const yourFunctionName = () => {
const anyname = document.getElementById("hide-me");
const frameId = document.getElementById("id-in-external-php");
const check = frameId.contentDocument.body.children
const c = check[0].innerText;
if(c.startsWith('Cannot')) {
anyname.style.display="none";
frameId.style.display="none";
} else {
anyname.style.display="block";
frameId.style.display="block";
}
}
window.addEventListener("load", yourFunctionName, false);
</script>
I did not see where you invoked the function, so i invoked mine when window load
I want my users to open their desired sites from my website, for this manner I need to insert a variable in src of iframe which change by user input strings.
Indeed I need a type of code like bellow:
<html>
<body>
<script type="text/javascript">
var userInput_stringVariable= "this part is user desired input string" ;
var adress= "https://en.wikipedia.org/wiki/" + userInput_stringVariable ;
</script>
<iframe src=adress width="100%" height="100%" frameborder="0"></iframe>
</body>
</html>
This code doesn't work, while I need a code like this to work with!
A textfield where user can enter whatever they would like to search on wikipedia or whatever website you want, a submit button which will call a function after it is clicked. answer.value will give the value of textfield and it's concatenated with website initial url.
HTML
<input type="text" name="inputField" id="answer" placeholder="Enter what you wanna search">
<button type="button" name="button" onclick="mySubmit()">Submit</button>
<iframe id="search" src="" width="100%" height="100%" frameborder="0"></iframe>
Script
<script>
function mySubmit() {
let getInput = answer.value;
var address;
address = "https://en.wikipedia.org/wiki/" + getInput;
document.getElementById('search').src = address;
}
</script>
Here is a function that will probably do what you want:
<script type="text/javascript">
function selectPage() {
var userImput_stringVariable = prompt("desired imput string");
if (userImput_stringVariable != null) {
document.getElementById("getPage").innerHTML =
"<iframe width='100%' height='100%' src='https://en.wikipedia.org/wiki/" + userImput_stringVariable + "'></iframe>";
}
}
</script>
Just add
<body onload="selectPage()">
somewhere in the body so the function runs when the page does.
It'll open a prompt, the user then has to enter the address.
Also you'll need this in the body too:
<p id="getPage"></p>
It creates a paragraph with the contents of the iframe within the fuction.
How do I force any iframe content to appear on top if the content is changed as if the link had the target="_top" attribute...
EXAMPLE 1: Normally this code is what would be applied in a page.
<script src="http://code.jquery.com/jquery-1.8.1.min.js"></script>
<script type="text/javascript">
if(top!=self){
top.location.replace(document.location);
alert("For security reasons, framing is not allowed; click OK to remove the frames.")
}
</script>
But I need to aply it to the iframe instead, and fire it only if the iframe is changed. How do I do that?
For example, I click on a link within the iframe, once that page changes URL then the iframe puts the page on target="_top" without having attributes for it in the iframe URL page, but the attributes for it should be from the iframe page itself.
EXAMPLE 2:
I have found a code that works as it should, the problem is only that it only fires when clicked on a button. Can I somehow make it to fire automatically when content of the iframe changes?
JavaScript:
<script type="text/javascript">
//<![CDATA[
$(window).load(function(){
document.getElementById('example-button').addEventListener('click', function (ev) {
ev.preventDefault();
var win = open('about:blank');
var iframe = document.getElementById('example-iframe');
setTimeout(function () {
var body = win.document.body;
body.style.padding = 0;
body.style.margin = 0;
body.appendChild(iframe);
iframe.style.position = 'fixed';
iframe.style.padding = 0;
iframe.style.margin = 0;
iframe.style.width = '100%';
iframe.style.height = '100%';
iframe.style.border = 0;
}, 100);
win.addEventListener('beforeunload', function () {
document.getElementById('example-container').appendChild(iframe);
iframe.style.position = '';
iframe.style.padding = '';
iframe.style.margin = '';
iframe.style.width = '';
iframe.style.height = '';
iframe.style.border = '';
});
});
});
//]]>
</script>
HTML:
<button id="example-button">open in new window</button>
<div id="example-container">
<iframe id="example-iframe" src="https://example.com/">
</iframe>
</div>
After fiddling and putting together with loads of ideas given online by others I came up with a solution that is 70% correct.
Now the only thing that remains is how to make it react ONLY when the iframe URL changes and not when loading like now.
JavaScript:
<script language="JavaScript">
function GoToURL()
{
var URLis;
URLis = document.URLframe.u.value
{
var location= (URLis);
window.open(location, '_blank');
}
}
</script>
HTML:
<form name="URLframe" id="URLframe" method="post">
<iframe id="test" src="https://example.com" onload="GoToURL(this);"></iframe>
<input type="hidden" name="u" size="71" value="" placeholder=" URL " id="SeekBox" onkeypress="handleKeyPress(event)">
<script type="text/javascript">
(function() {
document.getElementById('SeekBox').value = document.getElementById('test').src;
})();
</script>
</form>
To test it easier I used these codes at the bottom instead:
<iframe id="test" src="https://www.4shared.com/privacy.jsp" onload="loadurl();" width="100%" height="528px"></iframe>
<input type="text" name="u" size="71" value="" placeholder=" URL " id="SeekBox">
<input type="button" id="SeekButton" onclick="GoToURL(this);" value=" go ">
<input type="button" id="SeekButton" onclick="loadurl();" value=" load url ">
<input type="button" id="SeekButton" onclick="alerturl();" value=" alert url ">
<script type="text/javascript">
function alerturl() {
alert($('iframe').attr('src'));
}
</script>
<script type="text/javascript">
function loadurl() {
document.getElementById('SeekBox').value = document.getElementById('test').src;
}
</script>
If I understand you correctly then you want to get the src of the iframe any time there is a change within the iframe and then open a window with that src. If I'm right then it doesn't seem like it's possible. I tried to get the source of the iframe using this little bit of code but to no avail.
<iframe id="test" src="justanotherwebsite.com" onLoad="iframeLoad()"></iframe>
<script>
var counter = 0;
function iframeLoad(){
if (counter > 0){
console.log($('#test').attr('src'));
}
counter ++;
}
</script>
Let me know if I'm way off the mark on this and I'll have another look.
I have 2 embeds I am displaying. The embeds have a link to a pdf:
<div id="container" class="text-center">
<embed src="www.example.com/pdf1.pdf" width="550" height="800" type='application/pdf' id="mypdf1">
<embed src="www.example.com/pdf2.pdf" width="550" height="800" type='application/pdf' id="mypdf2">
</div>
I also have 2 buttons, one to show the embed and another to hide the embed. Like this:
<div class="button">
<button class="btn-info" onclick="hide('thePdf2')" type="button">HIDE</button>
</div>
<div class="button">
<button class="btn-info" onclick="show('thePdf2')" type="button">SHOW</button>
</div>
I use the following functions to show and hide the embeds:
<script>
function show(target) {
document.getElementById(target).style.display = 'block';
}
function hide(target) {
document.getElementById(target).style.display = 'none';
}
</script>
My I am only showing and hiding one of the embeds, my problem is this: Evertime I show the embed it reloads the pdf and goes to the top of the pdf page. I don't want to reload the pdf everytime I show it. How can I achieve this ?
Isn't reloading the PDF in my browser (Chrome), so I can't reproduce, but using .visibility instead of .display might work in your browser.
<script>
function show(target) {
document.getElementById(target).style.visibility = 'visible';
}
function hide(target) {
document.getElementById(target).style.visibility = 'hidden';
}
</script>
You could also use .show()/.hide() Jquery function. Working plunck here. FYI, also added demo of loading a selected PDF into single <emded>.
/* toggle show hide of pdf */
$(document).on('click', '.pdf-container button', function(event){
var $target = $(event.target);
var $pdfViewer = $target.closest('.pdf-container').find('embed');
if(!$pdfViewer){ return; }
if($pdfViewer.is(':visible')){
$pdfViewer.hide();
$target.text('show');
return;
}
$pdfViewer.show();
$target.text('hide');
});
I've iframe that i created dynamically in my html page and print button with event on click
to print iframe's content
but unfortunately it prints the whole page instead
but after long search
I've found some solutions like focus on iframe before fire print event
but it seems doesn't work on IE and MS Edge
it works in Chrome
the only solution that works with me is to open new window and copy iframe outerhtml in it and fire print event after the content loaded in new window
then close the new window immediately after the user take an action to print or cancel
but this solution doesn't look user friendly
so does it there any solution to print iframe content in IE and Edge

<br />
<button type="button" onclick="printIFrameContent();">Print IFrameContent</button>

<div style="border: 1px solid black; width: 300px; height: 200px;">
This is to test printing the content of an IFrame whose src is set dynamically.
</div>
</body>
</html>
You may first check if the user agent is IE:
function printIFrameContent()
{
var ua = window.navigator.userAgent;
var msie = ua.indexOf ("MSIE ");
var iframe = document.getElementById("testFrame");
if (msie > 0) {
iframe.contentWindow.document.execCommand('print', false, null);
} else {
iframe.contentWindow.print();
}
}
