JavaScript - Javascript Dropdown And Switching Content Without Page Reload
There are two pages,
folder/india.html folder/usa.html and dropdown menu in each page to switch between india and usa pages. india.html page sells in INR and usa.html in USD with links to shopping carts for each currency. link1(INR) link2(USD) Except the link and the currency information(selling price), contents in both the pages are same. So here comes the problem. Google hates duplicate pages! I am looking for a solution where, a single page In That Page, a dropdown menu to select currency As the currency is selected, without page reload, the link to shopping cart and the pricing also should be changed according to the selected currency. So Single page should be able to handle both the currencies. Kindly suggest me with codes as I am new to javascript. Thanks a lot Similar TutorialsHow can I execute this: From the dropdown list build up from mysql database (say a list of fruits). I select "Add New Fruit". This triggers it to either have a modal form to add new fruit or a table form. Once submitted, Select dropdown list RELOADS including the newly added data (fruit) without reloading the whole page which contains other form control such as textbox. So I'm trying to get one particular number from a game's grand exchange database. Say I wanted to know the 'Market price' of this item and the item results would change on click of a drop down box. I don't know how I'd go about getting that one section of the entire page though. Any help is appreciated. Code: <html>

how can refresh my website without interrupting of main content. suppose user reading a post in my website . during that i want to refresh my ads in my website without interrupting of main content. ex: go this link. http://www.novamov.com/video/xl58zuy4sd1a9 in this page site will automatically refreshes the ads every 1 minute without interrupting of main content. how can i do that in same manner. please help me. Hi, I am Aditya. I am explaining below the exact scenario where I need the help: I am developing a web application in which I need to integrate a javascript/html editor on some of the web pages and then provide 'Edit' buttons on those web pages so that users can edit the content on that partciular html/jsp page (like editing in wiki pages) and then, when they add some content and click on submit button, the new content should appear on the web page with all the formatting (i.e. bold, italics, color and so on) which was applied by user when he was entering the text. Now, I need help for the below issues: 1. Please suggest me a good javascript/html editor (freely downloadable) which I can use to integrate with my web pages. 2. Once the user has entered some content using the above javascript editor, how to make that content reach the server and update the corresponding web page. I am new to web development, so may be that these questions are too simple. But, I need some help from you. Waiting for your reply, Thanks, Aditya Howdy folks, New to Javascript programming. I was able to do decent javascript (getting refereces to various elements on a page and read attributes or set attributes)...but when I try to do same kind of programming in a content page, it misbehaves. For example a have a table element on the content page and button. in the onclick event of the button control, I am getting the <td> element and change its colors. but for some reason instead of changing the color of just the <td> element, the entire content page as well as Master page changes. can someone guide me please.

thanks I have a site where i switch between two images using some JavaScript. What I need is to be able to set a session variable or something so that if someone selects shading on or off it sticks to that for the rest of the session. Any idea or even a point in the right direction. Do i need cookies or is there a simple way to do this http://www.tech4t.co.uk/territorymapping/pentagon/ I'm trying to allow the user to change the stylesheet of my website. I can change the stylesheet on a page by page basis (eg. from red style to blue style) but once the user navigates to a different page the stylesheet resets back to the original setting. For example, when the user visits the site first its set to the red style, they can change it to blue but when they navigate to another page the style goes back to red again where as I want the style to stick across pages. Does anybody know how I can sort this out? I assume I'll have to edit my javascript but Im not very good at javascript so any help would be great! HTML Code: <html>
<head>
<link href="red.css" rel="stylesheet"
type="text/css" title="red" media="screen" />

Firstly, I'm a complete Javascript noob, so apologies if this is blindingly simple. I'm trying to write a piece of javascript that will check a single checkbox depending on a dynamically-imported piece of information further up the page. The page will look like this: Code: <div id="title">
<p class="white">1</p>
</div>
<div id="question">
<p>Please indicate your area(s) of interest below:<br />
<input type=checkbox value="1" /> Option 1<br />
<input type=checkbox value="2" /> Option 2<br />
<input type=checkbox value="3" /> Option 3<br />
<input type=checkbox value="4" /> Option 4</p>
</div>
The variable which indicates which checkbox should already be checked is in the div 'title' in the p class 'white'. So in the case above, when the page loads the 'Option 1' checkbox should already be checked. The javascript i have, rather poorly, cobbled together so far just doesn't work, and I was wondering if anyone could point me in the direction of some useful tutorials. All the tutorials I have read so far deal with mass checking all the boxes with a button click. 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 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. 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... I am running a simple show hide div script as follows: Code: <script type="text/javascript">
<!--
function toggle_visibility(slideshow) {
var e = document.getElementById(slideshow);
if(e.style.display == 'block')
e.style.display = 'none';
else
e.style.display = 'block';
}
//-->
</script>
<a href="#" onclick="toggle_visibility('slideshow');">Show Gallery + </a>
<div id="slideshow" style="display:none">slideshow</div>
It works but the page reloads and returns the user to the top of the page not to the "shown" div. Any way to send them back to the shown div or stop the reload? Any help would be appreciated. Thanks Hi all! I am trying to write code that does the following: 1) creates an array with 6 objects in it. 2) each object has a respective image. 3) from the 6, one object is selected as the "target" 4) all the 6 images are displayed on the screen with a hint as to which of the 6 is the target this time. 5) the user selects one of the 6 he/she thinks is the right object. 6) if the selection is right, his/her score increases by 1, and the whole process loops. The issue is I want the whole process to loop, but I want to store the users score somewhere otherwise it will get reset to 0 everytime the process loops.I've been told I could use cookies for this, but I've been reading a lot that cookies are outdated. Is there an easy way to do this without cookies? The required code is below: Code: <head>
<script language="text/javascript">
var redScore = 0;
....
targets = new Array(); // creating a new array with all the possible elements
....
fisherYates(targets); //randomizing the array
...
var theTarget = targets[0]; // selecting the element at index 0 to be the target
...
...
lots of code that is not relevant
...
...
function redClick( buttonLocation ) {
if(buttonLocation == redLocation){
redScore = redScore +1;
I need something here that will save the score and reload the page
}
}
...
...
</script>
</head>
<body>
<table>
<tr>
<td><img id="red0" onclick="redClick(0)" /></td>
<td><img id="red1" onclick="redClick(1)" /></td>
<td><img id="red2" onclick="redClick(2)" /></td>

I know this is quite complicated, so any help or direction would be much appreciated. Thank you! Hi I have created a very very simple javascript that displays random text quotes. It is in Greek but here it is anyway: http://gerogriniaris.blogspot.com It is in blogger and shows up as a gadget. My problem is that i need to make it reload by a button and at the same time go to the top of this gadget (using an anchor). The reason I want to do this is that I have been sharing this with other bloggers, but if they don't put it on top of their page, as soon as they press the button that reloads the page, they are in the top of the page and they would have to scroll down to find the quote. I have tried to use window.location.reload with window.location.hash. It works in Firefox, but not in IE. I have been trying something like that: Code: <input type="button" value="Click to refresh" style="width: 130px" onclick="window.location.hash='#something';window.location.reload()" /> As i said, this works with Firefox, but not with IE9 Also, I can't define urls beforehand because I want other people to be able to use it to their own blog or website. I suppose this is a noob question, but I have been trying to find a solution and couldn't. Please be kind... Any ideas? Hi. I have a form and in the form is a checkbox use as a switch to hide and unhide a two textbox. When the other textbox is hide, the other is unhide such as the code below. When the user click the submit button on the first time and there is an error, it reloads and the id="fieldset.-in_honor" hide because it is set to hide initially but not empty. My problem is, I want to show the fieldset whichever is not empty after submit button is click and there is an error so user will not enter any more information to the other field. Is that possible? Please help. I have a hard time explaining it but hopefully you will get the idea. Thanks in advance and hope to hear from you as soon as possible. Code: /*toggle switch*/
<p><input type="checkbox" name="in_honor" value="" id="checkmemoriam" onclick="showHide(this.name);" />Please check to make this donation in honor of someone special.</p>
/*hide textbox but unhide when the switch is on or the checbox is check*/
<fieldset id="fieldset-in_honor" class="fieldgroup" style="display:none">

<p>To make this donation in honor of someone special, please complete the two fields below:</p>

Trying to use js to reload an iframe so that it can do a query again and show a live update to the given number. I'm doing: <code> <iframe id="ifrm" name="ifrm" onload="ifrm.window.location.reload();" src="url" width="400px" height="100px" scrolling="no" frameborder="0"> Sorry, your browser doesn't support iframes. </iframe> </code> Any ideas? Hi I am trying to trigger an event once the user clicks the browsers back/forward buttons, I have built a system just like facebook where if the user has javascript turned on they get the full feature of the site which includes fast switching for example if someone goes to this page "example.com/index.php" and click a link to contact.php it would change the url to "example.com/index.php#!/contact.php" but what I need to know is if there is any way to change the pages content when the user goes back and forth through the fast switch pages? something like "history.back !== -1" or something like that. If anyone can help please reply, thank you. What I would like to do is have a page with a dropdown menu, and depending on which option the user chooses from the dropdown, reload the page and display a particular iframe below the dropdown, based on the users choice. Also, a default iframe would load (the one connected to the default choice in the select box). Hopefully that makes sense. I was trying to make this work with PHP (without having the user having to click a submit button) but I couldn't find a way to make it happen.
Hello Basically I have found and adapted the code: Code: alreadyloading = false;
nextpage = 2;
$(window).scroll(function() {
if ($('body').height() <= ($(window).height() + $(window).scrollTop())) {
if (alreadyloading == false) {
var url = "page"+nextpage+".html";
alreadyloading = true;
$.post(url, function(data) {
$('#projectscontainer').children().last().after(data);
alreadyloading = false;
nextpage++;
});
}
}
});
I want when the user scrolls to the bottom of the page for content in a new page to load under the div "#projectscontainer". So in the new page 'Page2.html" I have put 5 divs going down with content in... I want the new content to appear below "#projectscontainer'" Why won't this work? Anyone know? Thanks I created the following javascript to display info when you choose from a dropdown <table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td>View Local Contact </td> <td><select name="ContentListBox" id="ContentListBox" onchange="javascript:ShowDiv();"> <option value="">Select State</option> <option value="AK">Alaska</option> <option value="AL">Alabama</option> <option value="AR">Arkansas</option> </select></td> <td> </td> </tr> </table> <div id="AK" style="display:none;"></div> <div id="AL" style="display:none;"><div class="salesman">Marilyn O. Rogers </div> <div class="salesphone">Phone/Fax: 615-824-7804</div> <div class="salesemail">E-mail: <a href="mailto:morogers1@comcast.net">morogers1@comcast.net</a></div></div> <div id="AR" style="display:none;"><div class="salesman">Lonnie Muse</div> <div class="salesphone">Phone: 432-366-9213</div> <div class="salesemail">E-mail: <a href="mailto:muselon@sbcglobal.net">muselon@sbcglobal.net</a></div></div> When you choose the second one and then the third one the second choice does not disappear and it displays both. How can i refresh in between each one so that is displays only one? |
