JavaScript - Window Reload Event
I have cpa gateway on a site that when the customer completes a function of the gateway. The external js of the gateway sends a command to the website to reload the site. Is there any way I can have some sort of event listener to know if that command is sent or not? The problem I'm having is its causing a loop in my existing JS. So it keeps looping the page. I would like to be able to set a cookie when the command is sent and then just have the cpa gateway not load. Thanks all! I haven't been on here in awhile so I have been learning a lot on my own! But this one stumps me

Hello all, and thank you for your coments, I want to preserve a 16/9 aspect ratio to the window after any resize, making the width a function of the height. As I have a window.resizeTo() inside the window.onresize event function, the infinite loop is served. How may I quit it? Code: <html><head><title>Title</title><script languaje="javascript">
const c_ra=16/9;
window.onresize = function WindowReSize() {
var myWidth = 0, myHeight = 0;
if( typeof( window.innerWidth ) == 'number' ) {
//Non-IE
// myWidth = window.innerWidth;
myHeight = window.innerHeight;
} else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
//IE 6+ in 'standards compliant mode'
// myWidth = document.documentElement.clientWidth;
myHeight = document.documentElement.clientHeight;
}
myWidth = Math.floor(myHeight*c_ra);
window.resizeTo(myWidth,myHeight); // ** CAUTION resize event in a onresize event handler !
};

Dhiru Hi all, I have a HTML and I am opening another link in a separate window using window.open() . The child window is something like 'http://yahoo.com' which is out side html. I need to refresh the parent window when the child window is closed. any idea? Thanks, Mahesh hello, I am trying to add a window event listener on some links in a loop instead of doing them one by one. I've tried Code: function setListeners (){
for (var i = 0; i < document.links.length; i++) {
src=document.links[i].href;
document.links[i].onmousemove=changeIframeSrc(src, 'solid',1, event);
document.links[i].onmouseout=changeIframeSrc(null,'none',0,event);
}
}
and Code: function setListeners (){
for (var i = 0; i < document.links.length; i++) {
src=document.links[i].href;
document.links[i].onmousemove=function(a1,a2,a3,a4){
return function(){changeIframeSrc(a1,a2,a3,a4);}
}(src, 'solid',1, event);
}
}
but the event keeps coming up undefined. Any ideas on how to do this? If I use a window opener to open a new window, is there a way to detect that the new window is finished loading before carrying out some other directive in the opener window? Can I access the remote window's onload event from the opener window? I need to know that the website has loaded before moving to the next page. something like: remoteWindow.onload = goToPage(url); Is this even possible?

Regrads, Abha Hello, I'm working on a quote generator and I'm running into an issue with onChange events not firing when a text field is dynamically populated via a child window. Here's my setup: I have 3 text boxes (quantity, price, markup) that are multiplied together in order to give the total of that product. Each text box has an onChange event [called calculator()] that calls an external javascript file, which handles the multiplication and instantly updates the total of that product. Up to this point, everything works fine - - when I manually edit any of the 3 inputs, the total updates correctly. However, my problem is that I now have the "price" text box being dynamically populated, and when it updates it is not firing the onChange event attached to it. The text box is being filled by way of launching a child window and running the following code within it: Code: function call_submit()
{
opener.document.quote_form.item_price_1.value=document.child.prods.options[document.child.prods.selectedIndex].id
self.close();
}
I've also tried to call the calculator function from within the child window, with no luck: Code: function call_submit()
{
opener.document.estimator_form.item_price_1.value=document.child.prods.options[document.child.prods.selectedIndex].id
calculator ()
self.close();
}
So, as of right now, the following is happening - - I launch the child window, I select the product to add to the quote, the child window closes and the price is correctly populates within the "price" text box, BUT the total stays at zero. If I manually edit any of the fields, it then catches back up and properly updates the total. Is their any way to fire the onChange event at the time when the text field is populated from the child window? Any help would be appreciated. Thanks in advance. Hi forum, I am trying to attach an event to a dynamically produced button, and then use stopPropagation and preventDefault. Code: function chapter12_nodeOne() {
//create an element
var element = document.createElement('input');
//set some attributes
element.setAttribute('type', 'button');
element.setAttribute('value', 'submit');
element.setAttribute('id', 'myBtn');
//appendd the element into a DIV
document.getElementById('myDiv').appendChild(element);
//uses EventUtil to attach an event listener
EventUtil.addHandler(element, 'click', function() {
alert('event attached');
});
var flag = confirm('prevent default behavior of button?');
if (flag) {
var el = document.getElementById('myBtn');/////////////////////////(1)
var ev = el.onclick;
}
}
var EventUtil = {
addHandler: function(element, type, handler) {
//check if the element and the browser support DOM Level 2 event attachment
//if the user is not browsing with IE
if (element.addEventListener) {
element.addEventListener(type, handler, false);
}
//if user is browsing with IE
else if (element.attachEvent) {
element.attachEvent("on" + type, handler);
}
//if user is using a browser that only supports DOM Level 0 event attachment
else {
element["on" + type] = handler;
}
},
removeHandler: function(element, type, handler) {
//check if the element and the browser support DOM Level 2 event attachment
//if the user is not browsing with IE
if (element.removeEventListener) {
element.removeEventListener(type, handler, false);
}
//if user is browsing with IE
else if (element.detachEvent) {
element.detachEvent("on" + type, handler);
}
//if user is using a browser that only supports DOM Level 0 event attachment
else {
element["on" + type] = null;
}
}
};
But when debugging I see under el on the line marked with (1) that the onclick event is null. What am I doing wrong?! PS:the event is attached, when I click on the button I get an alert message is it possible to capture the control.event or element.event that was fired to invoke the onbeforeunload event. for example, if a button is clicked and it causes the onbeforeunload event to fire can i determine which button was clicked. thanks I have a ondrag event handler and in that I am trying to retrieve e.ClientX but it always return 0 in Mozilla. Works fine in IE though. How can retrieve the clientX and clientY in ondrag event? This is my dilemma and I am not sure if I am handling the right way, so please suggest a new way or provide a valid answer so that I may achieve my goal. Thanks in advance for your help in solving this matter. In short I have a single "A.html" page that uses AJAX to reload in "B.php" into a <DIV id='bDiv'> every second and "C.php" into another <DIV id='cDiv'> with no reloading. The code in B.php generates a random number between 1 and 100. If the number generated is less than 10, I want <DIV id='cDiv'> to refresh its content. I have tried a number of tricks, I could not find anything in jQuery so if there is please point me to the correct function calls. hello im working on my senior design project for my electrical engineering class. and part of the project is to upload an image via php (which ive written and it works great) but when the image is loaded into the same directory as the html file (which is supposed to display the image everytime a new image is uploaded) the image stays the same it doesnt show the new image. but i kno the new image has been uploaded because i can see it my web server. this is the code Code: <html>

var thisImage = "Lighthouse.jpg"; //the image location
var today = new Date(); //the current time
//add the time to the end of the image string
//to make a unique url:

I have a index page on which there are several iframes which point to pages from a tomcat server. Sometimes when the index page loads, most of the iframes display session expired error. When I refresh the page, all iframes load properly. I want to reload the page twice whenever I come to that page initially. I also want to reload that page twice when I come to it from another page. Any ideas are welcome. I have tried the following in the onload event ----------------- if(window.location.search.indexOf('reload')<0) window.location.replace(window.location.href+'?reload'); --------------- function loaded() { if (!navigator.fudge) { navigator.fudge = 0; } navigator.fuge++; if (navigator.fudge>1){navigator.fudge=0} else{location.reload()}; } ------------- if(readCookie('reloaded')!='Yes') { createCookie('reloaded','Yes',1); window.location.reload(); } else eraseCookie('reloaded'); function createCookie(name,value,days) { if (days) { var date = new Date(); date.setTime(date.getTime()+(days*24*60*60*1000)); var expires = "; expires="+date.toGMTString(); } else var expires = ""; document.cookie = name+"="+value+expires+"; path=/"; } function readCookie(name) { var nameEQ = name + "="; var ca = document.cookie.split(';'); for(var i=0;i < ca.length;i++) { var c = ca[i]; while (c.charAt(0)==' ') c = c.substring(1,c.length); if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length); } return null; } function eraseCookie(name) { createCookie(name,"",-1); } --------------------------- several meta tags to get the page each time from the server e.x. <META HTTP-EQUIV="Pragma" CONTENT="no-cache"> <META HTTP-EQUIV="Expires" CONTENT="-1"> Hey guys, I have read the past posts and I see that there have been some other people who have had issues with resetting a form. Right now - on this mess in progress - I have a function that runs on body load: Code: function load ()
{
document.forms[0].reset();
}
I know it is running because originally it was an alert, but this is not clearing the form. I need to get all checkboxes and fields to clear. I have also tried: Code: function load ()
{
document.getElementById("regForm").reset();
}

Hi, i'm not sure this is the right spot for my question ,but i will try. ( sorry if not ) I need to create a script, that sets cookie ,named "something" with a random $value - something(1-500) every time the user refreshes his browser. Something like this : Y.Node.get("#Button1").on("click", function(){ var newValue = "something" + Math.round(Math.random() * Math.PI * 500); Y.Cookie.set("$something", newValue); Y.log("Set cookie '$something' to '" + $something + "'"); But when i refresh the browser the cookie must be with a new Value. I will explain more clearly : I hit Button 1, Activate this script,that sets me the cookie named "something" with a $value for example , something55 I refresh my browser,the same cookie has $value for example something98 Thanks in advance, Regards, Anton P.S. i'm trying to make it work for a few days .so i will be very glad if someone could help me here . Hi, I am using javascript function for refreshing html page. I have used [window.location.reload(true);] method to reload page from server. This code works if i use it by using Link/button etc. For Example: <input type="button" value="Refresh" onclick="window.location.reload(true);" /> But i want to refresh page when page loads. For Example: <body onload = "window.location.reload(true);> But this time, page reloads in an infinite loop. i don't know why... I have also used following function (against body onLoad) to reload and then stop, but this also does'nt work. function doLoad(){ var timeoutId = setTimeout( window.location.reload(true), 1000 ); window.clearTimeout(timeoutID); } Is there a way to stop reloading page after one refresh ? Thanks... Hi... I am having a problem with the resize... I use the script below to adjust the size of the frame. It works nicely for me. The only problem is, the frame initially jumps to the bookmark, and then on the reload, jumps to the top of the page. Any ideas on how to keep the frame at the bookmark in the web page, instead of jumping back up to the top???? Thanks much in advance.... <script> <!-- function resize_iframe(){ if ( window.frames["MainWindow"].document.body.scrollHeight=0 ) { } else { document.getElementById("MainWindow").height=100 document.getElementById('MainWindow').height=window.frames["MainWindow"].document.body.scrollHeight + 20 } } // --> </script> <IFRAME src="main.htm" frameborder="0" scrolling="no" ID=MainWindow NAME=MainWindow HEIGHT=800 WIDTH=1012 onLoad=resize_iframe();></IFRAME> |
