JavaScript - Innerhtml() And Location.reload() Problems
I have several links that when a user clicks on one of them, it calls a javascript function that injects html using the innerHTML function. Lets say I wish to go to a different link, i would like to remove the already existing code and replace it with code that is called by the new function when the user clicked on the new link. I have already done a variation of parent.removeChild(element); and it didnt work properly. I have also tried location.reload() function but it seems to be refreshing the window AFTER i inject the html code with innerHTML function. Any ideas why it is doing this? It should refresh the window first and then execute the next line of code. It has been quite a frustrating experience for me.
Here is a generalization of my code below: 1) event from anchor 'About Me': onClick executes function menuParser('aboutme') 2) switch statement in menuParser() executes code to inject html using innerhtml() 3) user decides to navigate to another anchor 'Science': onClick executes function menuParser('science') 4) in function menuParser() a parameter is tested to see if there is any injected code already 5) condition passes true and location.reload(); is executed 6) then code is injected again using innerhtml() I can see the changes made in a split second, then the entire page is refreshed. Any ideas? Thank you! -Nick Similar TutorialsHello everybody What i am doing is: I reload a page periodically and do so with Code: document.location.reload() The Reload is implemented using Code: window.setInterval This works fine, except there is the problem with the focus: If the page with the reload bevaviour is in the background and i have another page in another IE window in the foreground, when the reload is called, the page with the reload in it steals the focus and is now in the foreground. Is there any way to avoid this behaviour? I'm using IE 7. Any help is greatly appreciated. Is there a difference between right clicking an iframe and reloading post reponse vs. using javascript to reload the frame? So far, the javascript route hasn't worked for me. [some context] I am writing a little bookmarklet to help me with the online registrations at my school. Here is the setup. Load up a page on the domain. Remove all body elements. Insert an iframe. Set iframe to page for class roster search. (in iframe on school search page) Select class search options, POST the form data, and view results in frame. *This works perfectly, but I need to have it refresh results every minute or so. When I use frame.contentDocument.location.reload(true); the frame loses the post data or something and the page is broken. BUT when I just right click on the frame and select "reload frame" it works perfectly. Whats the deal here? What is the difference between rightclicking the frame and refreshing it like that vs. using javascript to reload the frame? PS: using chrome Hello. I have the following: bottomCell.innerHTML = "apples 0"; bottomCell.innerHTML.replace("apples", "oranges", "gi"); The first line works fine, the second one doesn't. In the end, I want it to replace all instances of the numerical variable named myNumber to the string "t" + newNumber (where newNumber is another numerical variable) but neither this, nor the above mentioned line work. Any ideas? Thanks! Hey guys, I'm trying to hide a TR if a TD within it has only specific html in it. Why would this not work: Code: if(document.getElementById('website1').innerHTML.toLowerCase()=="<a href='' title=''></a>")
{
document.getElementById('website-row').style.display='none';
}
Code: <script language="JavaScript" type="text/javascript">
function confirmDelete(url){
var decision = confirm("Click OK to delete this post.");
if(decision == true){
window.location = url;
}
}
</script>
<!--HTML LATER ON -->
<a onclick="confirmDelete('deletePost.php?id=17')" href=''><img src='delete.png' alt='' title='Delete this post' /></a>
I get absolutely nothing out of this. The confirm box pops up, but a the URL never changes when I click OK. I have no clue what's going wrong here. I'm using Google Chrome to test this out if that helps. Also does not work in Firefox. Hi, I'm using the following Javascript code to show a div layer depending on the URL Code: <script type="text/javascript">
if (location.href.match(/folder/)) {
document.getElementById("div-layer").style.display="block";
}
</script>
This works perfectly when I visit http://www.domain.com/folder but I do not want it to match any subfolders beneath /folder, for example: http://www.domain.com/folder/sub-folder http://www.domain.com/folder/sub-folder2 etc. Does anyone know how I can modify the code to only match /folder or /folder/ and no subfolders beneath it? Thank you in advance. What are the differences between results of these two. Code: window.location.hostname or Code: document.location.hostname 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>
<head>
<title>Human Cam</title>
<script type = "text/javascript">
function refresh() {
var refreshTime = 5*1000; //5000ms
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:
document.images["pic"].src=thisImage+"?"+today;
//reload if the images are loaded:
if (document.images) {
window.onload=refresh;
}
//IF the time is up reload the image
t=setTimeout('refresh()', refreshTime);
}
</script>
</head>
<body onload="refresh()">
<center>
<h2>human cam</h2>
<img src="Lighthouse.jpg" id="pic">
</center>
</body>
</html>
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"> 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> topic has been answered
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'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 . 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 Eric. Hi all, I'm new to javascript and html so this may be a silly question, and I'm sorry if I'm posting this in the wrong forum section. Anyway, I need some kind of javascript that will work in a framed page. Right now when I try to navigate to another framed page located elsewhere on my website it's pulling it up in that frame, so it's an ever expanding framed webpage. I need it to simply open the new page up in the whole browser, and not in the individual frame.. Any help is appreciate, (There may as well be an html solution but I couldn't find one)... Thanks. If multiple pages reference the same external JS sheet, does the sheet reload every time you go to a new page or does it stay in memory?
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();
}
No dice. Any idea what I am missing? The temp page is he http://www.temp1.hangnailproductions...ISTRATION2.php My script is he http://www.temp1.hangnailproductions...egistration.js Thanks guys, sorry if things are clunky and sloppy, I'm doing my best but still pretty bad. -AJ Hey, for some reason, this isn't working because of the src="images/edit.png" attribute. Here is my code: Code: <a href="#" onclick="change('HEYYY')"><img src="images/edit.png" alt="Edit" id="edit1" /></a>
Javascript (External) Code: function change(message)
{
document.getElementById('edit1').innerHTML = '<input type="text" value="'+message+'" />';
}
It does nothing. But if I take the src attribute out, it works fine. Any help? Thanks. Does anyone have any suggestions as to how I can get IE working properly with this? It's a, (exempting IE), straight forward line numbering and plain text code view function. When using the line numbering portion, it works fine in Moz based browsers etc, as it does in IE for the initial numbering. On trying to remove the numbers though, (on the second call), IE just seems to cascade the list entries rather than removing them. Code: function process_code(id, number, print)
{
if (document.getElementById(id))
{
var current = document.getElementById(id);
var code = current.innerHTML.split('\n');
var count = 0;
var xcount = 0;
if (number)
{
if (current.innerHTML.indexOf('<li class="code-entry">') != -1)
{
code = code.join('\n');
code = code.replace(/\<\/(li\>\<\/ol|li)\>/ig, '\n');
code = code.replace(/\<ol\>\<li[^\>]+\>|\<li[^\>]+\>/ig, '');
current.innerHTML = code.replace(/^\n+|\n+$/g, '');
}
else
{
current.innerHTML = '<ol><li class="code-entry">'+code.join('</li><li class="code-entry">')+'<
/li></ol>';
}
}
else
{
var doc = window.open('', 'code_print');
var newdoc = doc.document;
newdoc.open('text/plain');
newdoc.write(decode_code(code.join('\n')));
newdoc.close();
if (print)
{
if (navigator.userAgent.indexOf('Opera') != -1)
{
window.print();
}
else
{
doc.print();
}
doc.close();
}
}
}
}
