I have a transperent iframe, which created by next JS function:
Frames.prototype.CreateIframe = function (frameName, frWidth, frHeight, zindex) {
var frameObj = document.createElement('iframe');
frameObj.width = PX(frWidth);
frameObj.src = 'Content.htm';
frameObj.height = PX(frHeight);
frameObj.id = frameName;
frameObj.name = frameName;
frameObj.frameBorder = 0;
frameObj.allowTransparency = 'allowtransparency';
frameObj.style.zIndex = zindex;
frameObj.style.position = 'absolute';
frameObj.style.scrolling = 'no';
frameObj.style.scroll = 'no';
frameObj.style.overflow = 'hidden';
frameObj.style.left = PX(0);
frameObj.style.top = PX(0);
GlobalClass.AppendChild(window, frameObj);
}
Below that is another iframe where the images are placed. I created event handlers for these images. For example document.GetElementById("MyImage").onclick(alert("Click!"));
If I run it by IE, everything works fine. But I run it by Chrome, Firefox, Opera nothing works. How I can correct this?
The upper transparent iframe has event handlers and it works in IE also.
document.GetElementById("MyImage").onclick= function(){
alert("Click!");
}

I want clicking on an "expando" to toggle between its states: expanded and collapsed.
I'm still pretty new to DOM/JS, so my style here is probably awful; If you have any style guidelines let me know, but for right now I want to get the code working. I've tried a few different ways, like setting the expand or collapse behavior in dom's onclick (and changing it in the expand and collapse functions), but if I do that, then for some reason clicking doesn't trigger a collapse, but it will trigger an expand.
The problem with the code below is that I can expand an expando, but when I click on it, it also triggers the collapse, so it expands and then immediately collapses back.
var expandos = document.getElementsByTagName("expando");
var uid = 0;
for(var i=0; i<expandos.length; ++i) {
var dom = expandos[i];
dom.id = "expando_"+uid++;
var iframe = document.createElement("iframe");
iframe.src = dom.innerHTML;
iframe.name = dom.id +".big";
iframe.id = iframe.name;
iframe.scrolling = "no";
iframe.style.display = "inline";
iframe.onclick = collapse(dom);
var p = document.createElement("p");
var text = document.createTextNode(dom.innerHTML);
p.id = dom.id+".small";
p.style.display = "inline";
p.appendChild(text);
p.onclick = expand(dom);
dom.innerHTML = "";
/* We have to clear the innerHTML to prevent the original text from
showing up in addition to the text added by p.
*/
dom.appendChild(iframe);
dom.appendChild(p);
/* We have to append iframe and p **after** we clear innerHTML
because otherwise clearing innerHTML will clear the appended
children.
*/
function expand(dom) {
return function() {
alert("Expanding "+dom.id);
var iframe = document.getElementById(dom.id+".big");
var p = document.getElementById(dom.id+".small");
p.style.display = "none";
iframe.style.display = "initial";
dom.onclick = collapse(dom);
}
}
function collapse(dom) {
return function() {
alert("Collapsing "+dom.id);
var iframe = document.getElementById(dom.id+".big");
var p = document.getElementById(dom.id+".small");
p.style.display = "initial";
iframe.style.display = "none";
dom.onclick = expand(dom);
}
}
collapse(dom)();
}
The sample HTML I'm testing on:
<body>
<expando>The quick brown</expando> fox jumps over <expando>the lazy dog</expando>.
<script src="loadExpandos.js"></script>
</body>
In the same directory, I have files named "The quick brown" and "the lazy dog", and they expand properly.
A quick fix for to get the basic functionality you want is to combine your expand and collapse into a single function and have an if/else block that checks the state. Not 100% on what caused your original issue, but I'd guess it has something to do with your onClick events not being cleared.
function clickHandler(dom) {
return function() {
var iframe = document.getElementById(dom.id+".big");
var p = document.getElementById(dom.id+".small");
if(p.style.display === "initial"){
p.style.display = "none";
iframe.style.display = "initial";
} else {
p.style.display = "initial";
iframe.style.display = "none";
}
I forgot to include 'run multiple times in one page' on my last question located here: Create iframe with javascript appending to a div
I need to run the code on multiple div's within the same page. Right now the code below only runs once on the last div. For example if I have 3 div's, all 3 should have an iframe appended to it. Regular javascript. Trying not to use JQuery.
window.onload = function(){
var link = "http://www.somesite.com"
var iframe = document.createElement('iframe');
iframe.frameBorder=0;
iframe.width="300px";
iframe.height="250px";
iframe.id="randomid";
iframe.setAttribute("src", link);
document.getElementById("ad54").appendChild(iframe); //<--this id will be dynamically generated to match div's
}
<div class="ad" id="1"></div>
<div class="ad" id="2"></div>
<div class="ad" id="3"></div>
EDIT: Tested in IE9, Chrome, Safari, Firefox and opera. This code works. No JQuery or loops needed. This code will create the iframe wherever you use it.
var link = "http://www.somesite.com"
document.write(iframe);
var myIframe = parent.document.getElementById("randomid");
myIframe.height = 250;
myIframe.width = 300;
myIframe.src = link;
myIframe.style.border = "0px";
myIframe.style.padding = "0px";
window.onload = function() {
var elements = document.getElementsByTagName('div');
for (var i = 0; i < elements.length; i++) {
append_iframe( elements[i] );
}
}
function append_iframe( div ) {
var link = "http://www.somesite.com"
var iframe = document.createElement('iframe');
iframe.frameBorder=0;
iframe.width="300px";
iframe.height="250px";
iframe.id="randomid";
iframe.setAttribute("src", link);
div.appendChild(iframe);
}
Not a jQuery guy but I think this works
$("div").each(function(d) {
var link = "http://www.somesite.com"
var iframe = document.createElement('iframe');
iframe.frameBorder=0;
iframe.width="300px";
iframe.height="250px";
iframe.id="randomid";
iframe.setAttribute("src", link);
this.appendChild(iframe);
});
This is my code.Its working fine on firefox
<script language="JavaScript"type="text/javascript">
window.onload=function createDiv()
{
var body = document.getElementsByTagName('body') [0];
var div = document.createElement('div');
div.setAttribute('id','errorMessage');
div.setAttribute('class','blockMessage');
var text = document.createTextNode('TO close the message click on cancel');
var closeText=document.createElement('span');
closeText.setAttribute('id','close');
closeText.setAttribute('onclick','destroyObject()');
var text1=document.createTextNode('Close');
closeText.appendChild(text1);
div.appendChild(text);
div.appendChild(closeText);
document.body.insertBefore(div, document.body.firstChild);
//body.appendChild(div);
}
function destroyObject(){
var getId=document.getElementById('errorMessage');
getId.remove(getId);
}
</script>
As workaround, you could add some more code if its IE, like:
//for class
div.className = "your_class_name";
//for onclick
div.onclick = function() {destroyObject();}; // for IE
See here for more
For old versions of IE (6/7) use can use properties instead of attributes:
div.id = 'errorMessage';
div.className = 'blockMessage';
closeText.onclick = destroyObject;
Yes, I've searched high and low on Stack Overflow and seen some great solutions to this problem that's been solved time and time again with things like SimpleModal, jQuery.confirm and the like.
Problem is, I am developing for this low level device that doesn't allow for a JS framework to be utilized AND I am having to shoehorn this modal confirm into existing JS.
There is an existing script that I am at liberty to edit (but not rewrite) that does a few things like validate, concatenate a few inputs into a single variable, and more.
The script was written to:
Take some session variables and assign new variable names to them and format accordingly
Present a confirm to the user to see whether they want to use those variables to pre-populate the form on the page
Get some functions ready to validate inputs.
other stuff, like offer an abandonment scenario, among other things
Now, all was good when the "confirm" was in place as the script would pause until an OK or Cancel was provided. I am now presenting a modal on the page that I want to mock this behavior and the only way I can think of doing it is to remove that reliance on the line that goes through the confirm thing and NOT run the script until the user interacts with the modal.
Does anyone have an idea how to take what's in place and "wrap" it in a "listening" if/else scenario for each of the YES or NO possibilities?
Sorry if this is jumbled... my brain is all blended up at the moment, too.
As far as I know there is - so far - no way to halt scripts like the Browser specific alert() or confirm() Dialog does.
Frameworks like dojo for example try to mock this behaviour by putting a transparent DIV over the whole window to prevent clicks or other input while the Dialog is showing.
This is quite tricky as I have experienced, since Keyboard-Input may be able to activate Input Fields or Buttons behind this curtain. Keyboard Shortcuts or Field-Tabbing for example.
One sollution is to disable active Elements manually, which works quite well with me in most cases.
One or more function is passed to this "mock" Dialog to execute when an option was chosen.
Escpecially with ajax background activity the responsibilty to stop conflicting function calls while the Dialog is open lies with the developer.
Here is an example I came up with:

In this code there is still an error concerning the availability of the stored choice-function (undefined) at execution time. The function variable is no longer available in the closure. If anyone has a sollution for this you are welcome to add to it.
Hope that comes near to what you need to know.
Updated version: fixed choiceAction undefined, added IE compatibility. Internet Explorer is one main reason to use this, since confirm() is now blocked by default.

I want to load a form into an iframe. The iframe will be loaded into a random page when the user clicks the bookmarklet.
Here is the code so far:
loginForm = document.createElement("form");
loginForm.setAttribute("method","Post");
loginForm.setAttribute("action","http://devserver:8000/action/");
parameters = {};
parameters['url'] = parent.window.location;
for(var key in parameters)
{
var hiddenField = document.createElement("input");
hiddenField.setAttribute('type',"hidden");
hiddenField.setAttribute('name',key);
hiddenField.setAttribute('value',parameters[key]);
loginForm.appendChild(hiddenField);
}
loginIFrame = document.createElement('iframe');
loginIFrame.src = "about:blank";
loginIFrame.appendChild(loginForm);
loginIFrame.style.top = "0px";
loginIFrame.style.position='fixed';
loginIFrame.style.display = 'block';
loginIFrame.style.zIndex = 100;
loginIFrame.style.border = "solid #48D236 10px";
loginIFrame.height = "25px";
loginIFrame.width = "100%";
loginIFrame.style.border = 0;
loginIFrame.id = "loginFrame";
loginIFrame.name = "loginFrame";
usernameField = document.createElement("input");
usernameField.type = "text";
usernameField.size = 8;
usernameField.name = "usernameField";
usernameField.id = "usernameField";
passwordField = document.createElement("input");
passwordField.type = "password";
passwordField.size = 8;
passwordField.name = "passwordField";
passwordField.id = "passwordField";
submitButton.style.position='fixed';
submitButton.style.top = "60px";
submitButton.type = "button";
submitButton.value = "Submit";
submitButton.onclick = function(){loginUser();};*/
b.style.position="relative";
addToBody(loginIFrame);
loginForm.submit();
What ends up happening is the entire page gets reloaded on the submit (last line of code) rather than the iframe. Any ideas?
Thanks in advance
You might want to try adding the form using loginIFrame.contentWindow.document instead of loginIFrame.appendChild.
You might also need to add your form after the iframe has been added to the page since the contentWindow property won't be available.
I could be wrong, but I'm pretty sure that form isn't being added to the iframe, because you are using appendChild. I really don't think you can manipulate it that wa since it will be loading the URL you tell it to load (i.e. about:blank).
Edit: You might also want to add loginForm.setAttribute("target", "loginFrame");
Here is what I've been testing with and it works fine:
loginIFrame = document.createElement('iframe');
loginIFrame.src = "about:blank";
loginIFrame.style.top = "0px";
loginIFrame.style.position='fixed';
loginIFrame.style.display = 'block';
loginIFrame.style.zIndex = 100;
loginIFrame.style.border = "solid #48D236 10px";
loginIFrame.height = "100px";
loginIFrame.width = "100%";
loginIFrame.style.border = 0;
loginIFrame.id = "loginFrame";
loginIFrame.name = "loginFrame";
document.body.appendChild(loginIFrame);
var idocument = loginIFrame.contentWindow.document;
loginForm = idocument.createElement("form");
loginForm.setAttribute("target", "loginFrame");
loginForm.setAttribute("method","Post");
loginForm.setAttribute("action","http://devserver:8000/action/");
parameters = {};
parameters['url'] = parent.window.location;
for(var key in parameters)
{
var hiddenField = idocument.createElement("input");
hiddenField.setAttribute('type',"hidden");
hiddenField.setAttribute('name',key);
hiddenField.setAttribute('value',parameters[key]);
loginForm.appendChild(hiddenField);
}
loginIFrame.appendChild(loginForm);
loginForm.submit();

Possibly set the form target to the iFrame. I'm imagining, since you're creating elements within the "parent" page context, it's using the main page as a target (even though it's embeded).
EDIT
You could also try calling createElement from the iFrame after you've created it to keep context too.
