JavaScript - Count Occurrence Of Element In One Page And Deliver To Another
I am trying to set up a script that looks in the code on one page, counts the number of instances of an element by ID, and then delivers that information back to another page in order to set the height for an area on that page.
Context: I have a PHP page with an include statement and the included content is overflowing. Scrolls won't emerge (IMO) unless the container PHP page is told what is the height of the included content. I know almost nothing about javascript, so this is becoming a significant challenge. I cobbled together two scripts, just to get started: one that searches for occurrences of a word in a document, and another that converts that information into the height for the "div" tag in my PHP page. Obvious issues: 1) The first script will not search outside of the form for the word occurrence. I don't even want the count to be delivered in a form; I want it passed to the second script without any user involvement at all. 2) I am not sure how to set write the code so that it searches another document entirely. I bookmarked this site thinking that there might be some solutions in there. Code: <script language="Javascript">
function countInstances(string, word) {
var substrings = string.split("navpic3");
return substrings.length - 1;
}
</script>
<script type="text/javascript">
var thumbinstance=countInstances
var thumbheight=[(50*thumbinstance)+300]
function menuspace(images){
document.write("<div style="+'"'+"height: "+thumbheight+"px;"+'"'+">")
}
</script>
<script type="text/javascript">menuspace(255)</script>content</div>
<form>
<input type="label" name="string" value="navpic3 navpic3">
<input type="button" value="count instances" onClick="document.write(countInstances(string.value))">
</form>
Thanks in advance for any help. Elizabeth Similar TutorialsI have a html page with a lot of thumbnails. The idea is that when the user clicks on an image the onClick event is to display another detailed form and deliver to that form the name of the image in a variable. In the detailed php-form there is a query to MySQL to retrieve a record. The record will be retrieved by a Query based on the name of the picture. Apparently the PHP cannot do the job. I had an idea to make the thumbnail page as a form and to use use a hidden field with the thummnail name which should be carried on with the $_POST array through the submit button but i do not want to have a submit button. The more elegant way is just by clicking the picture the detailed page is opened and the variable is transferred where my php code can make use of the variable for the query. I have never used java before so you have to excuse for the lack of knowledge. Can anyone gie me an idea how i should implemnt this Best regards MSP I have a html page with a lot of thumbnails.

I am only beginning. I know how to edit most codes I come by to make them work for what I need them for, but I haven't really been able to get this concept to work. I know there is a way to count the characters of a text box. I have used them a thousand times. (Think twitter) I am making a forum, and I am not self-hosting. So I don't have access to change all of the HTML on the forum software. So, here is what I want to do, and I really just need to know if its possible. There is a reply box on this forum. A pre-existing element. It cannot be changed by going into the html, because I don't have access to it. I want a box to appear underneath it to count the number of characters that are typed into that box, and cut off if they go over. I know of codes that allow you to count characters in a box you create, because you can add the "onkeyup=" to the html... I just don't have access to that part. Do you see where I'm getting at? So to further illustrate, something like this: If it can be done, can someone show me how? I have the idea of how it might work, but I don't know enough to make my own code, only enough to figure out what existing code is talking about. I am sorry if this doesn't make sense. I can try to explain further if need be. Hello. My goal is to load the JS for a specific element before displaying that element. I integrated a third part script, and it works well. I set the timer he The JS is in my heading as <script type="text/javascript" src="countdownpro.js"></script> About mid-body I have: <span id="countdown1">2010-07-20 00:00:00 GMT+00:00</span> which allows for the setting of a target date to countdown to. When the page first loads it shows the above long format target time, until the js/meta tags kick in to modify it to just show the actual countdown as 00:00:00. I have attached countdownpro.js to this post. I tried shifting the function CD_Init() to the top of the script, and also appended it inline with the .html. I tried setting the big external script to "defer", but neither arrangement worked. I also tried placing the src file right at the top. I appreciate your help. Is it possible to convert "xyz123456xyz789" into "123456xyz789"? What I'm trying to say is, remove the first occurence of "xyz" from the string, so that all the other occurrences of "xyz" that aren't the first one, remain. Help is appreciated. Thanks, Jazzo Hello, I'm trying to remove one of the $ signs from this string below. I've gotten as far as removing them both. I'm having trouble removing one of them. Can someone help?

FYI http://www.hotscripts.com/forums/jav...croll-how.html Hi there, and happy new year. I am looking for a javascript code with the effect used by Google in the following example; http://www.google.co.uk/search?q=che...ient=firefox-a ... whereby the map scrolls with the page once it has been reached by the top of the browser. If anyone could point me in the right direction I would be very grateful. Many Thanks, Patrick.

Ive googled the internet like crazy for an answer for this, but couldnt find it. Im trying to create an animation. My question is, how do i change the width of a div onclick? Essentially, I want it to add one percent of the value of the width of the div every one second.. PHP Code: <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Loading Bar</title> <script> var x = getElementById("loadbar").style.width; function load(){ setTimeout ( "progress()", 1000 ); } function progress(){ x++; } </script> </head> <body> <div id="load" style="border:thin solid #6699FF; width:300px; height:10px"> <div id="loadbar" style="background:#6699CC; width:0%; height:100%"> </div> </div> <a href="#" onclick="load()">Click to load</a> </body> Its about this: http://www.wduffy.co.uk/blog/keep-el...omment-page-1/ Everywhere is used for a whole div on some side and when its on the top of the page. But what if its in the middle..? Look here - http://phpbb.bg/viewtopic.php?f=14&p=1013#p1013 Scroll down and then up.Anyway to fix this? Does anyone know what's wrong with this code because when the page loads, the link is not being hidden Code: window.onload = setTarget;
function setTarget()
{
var theLinks = document.getElementsByTagName('a');
for(var i = 0; i < theLinks.length; i++)
{
if(theLinks[i].getAttribute('href') == '/subjects/new')
{
theLinks[i].style.display = "none";
}
}
}
Hello. I have a table with td elements containing numbers in one row and td elements containing textareas in the second row like this: http://motionsroom.com/example.html I want to find an easy way for the user to click, draw a rectangle around or whatever around any several numbers so that they they would be put in a single td element instead of two or three (so we would have: "49 and 12" as the new value) and then the textareas below would also merge. Ideally, I would like to have a rectangle like in RTS games but then I would settle on whatever is easy. Is there any way I could do that? Thanks! Hi. I am very new to javascript, so I might not even be wording my question right, but I am going to try and be as concise and specific as possible. I am using jquery on my website- the galleria plugin- to make a slideshow. you can see the completed show he http://www.pauljameswilliams.com/demo2a.html This slideshow will be one of three on my website. Each slide show will opperate the same exact way.I have built in tabbed navifation, and the slideshows will all be accessable under the "portfolio" tab by clicking on their corresponding links. check out the site he http://www.pauljameswilliams.com/portfolio.html As it is I have one slideshow up, although not yet connected to the corresponding link, but the images won't load. My guess is that because the div tag is hidden that the contents don't load propperly and I need the contents to load when the corresponding div tag that it is contained in becomes visible but I don't know how to do that. this is the javascript that I have written to show/hide the <div> tags where the content will live. Three slide shows will live in content_2 and show/hide when the corresponding button is pressed. Code: function tabSwitch(new_tab, new_content) {
document.getElementById('content_1').style.display = 'none';
document.getElementById('content_2').style.display = 'none';
document.getElementById('content_3').style.display = 'none';
document.getElementById('content_4').style.display = 'none';
document.getElementById(new_content).style.display = 'block';
document.getElementById('btn_1').className = '';
document.getElementById('btn_2').className = '';
document.getElementById('btn_3').className = '';
document.getElementById('btn_4').className = '';
document.getElementById(new_tab).className = 'current';
}
thank you- I am really stuck. i promise, i am actually learning javascript, I'm not just trying to get other people to do my work for me. Looking for a simple way to have a hidden element made visible when the page scrolls. The idea is to have a back arrow appear only when the page has been scrolled horizontally. trying something along these lines without success ... Code: <script type="text/javascript">
window.onscroll = function () {
if $("back").is(":hidden") {
$("back").show("slow");
}
}
</script>
The site is he www.milesjaffe.com. Thanks -- Hello, I am trying to copy data from one element to another on page load. Below is the scenario: I want to copy the below data within each element <h2>Product Name</h2> <div class="price">$9.99</div> To the different parts of this URL <a href="https://myaccount.foxycart.com/cart?name=PRODUCT NAME&price=PRICE" class="foxycart">Add to Cart</a> Thank you in advance for your help. I have a floating div that stays at the bottom of the browser window while the user scrolls down a long page. The div reads "scroll down for more". How can I determine the current position of the div in relation to the top of the page, not the top of the browser window. I need to determine this because I would like to hide the div when the user scrolls to the top of the last page. I have looked at offsetParent, offsetHeight, scrollHeight, etc. I have the code for everything except determining the position of the div, or the distance of the div from the top of the page. I've been handed an html document that contains a centered, scrollable <iframe> element with a static height and width. This iframe element displays a simple html document that houses the 'terms of service' text. Their goal is to have it to where the <a href> link at the bottom that is shown to the user as 'next' is disabled until the user scrolls to the bottom of the terms of agreement box. The clickable link could be a button, image or text (no preference). They have to have it this way for legal reasons and radio buttons or checkboxes will not suffice unfortunately. Question: What is the best way to go about doing this that seems to be cross-browser friendly (especially IE7). I offer $10 via paypal for well commented method/script.

What it's saying isn't actually true (I don't think)... this is how the section is laid out: Code: <div id="submenu1" class="anylinkcss"> <ul> <li class="contact-pm"><a href="/index.php?do=pm&act=new&to=$RateViewProfileUserName$&returnurl=$ReturnURL$">PM me</a></li> <li class="contact-email"><a href="/index.php?do=email&id=$RateViewProfileUserId$">E-mail me</a></li> <li class="contact-msn" id="msn1">$RateViewProfileUser-profile_msn$</li> <li class="contact-yahoo" id="yahoo1">$RateViewProfileUser-profile_yahoo$</li> <li class="contact-skype" id="skype1">$RateViewProfileUser-profile_skype$</li> <li class="contact-facebook" id="facebook1"><a href="$RateViewProfileUser-profile_facebook$"><span id="fbook-add"></span></a></li> </ul> </div> <script type="text/javascript" src="/html_1/js/contact-information.js"></script> Does anyone know why this might error in just IE? Hi, I'm relativly new to JS and brand new to the forum so you might need to dumb down your replys for my slightly lacking knowledge. That being said I do have a very solid grasp of html, css and am getting there with JS and its various frameworks. I'm integrating wordpress into an existing site for a friend and currently have the main blog page appear in a DIV. This is the best way to integrate in this case due to many reasons mostly of way the site is constructed. Code: <div class="scroll-pane" id="scrollbox"> WORDPRESS BLOG </div> My issue is that links within that DIV, in the blog, when clicked redirect the page. The simple answer to this would be to have them just open in a new page, which I can easily do with the below code. Code: function Init()
{
// Grab the appropriate div
theDiv = document.getElementById('scrollbox');
// Grab all of the links inside the div
links = theDiv.getElementsByTagName('a');
// Loop through those links and attach the target attribute
for (var i=0, len=links.length; i < len; i++) {
// the _blank will make the link open in new window
links[i].setAttribute('target', '_blank');
}
}
window.onload = Init;
But what I'd rather it do is have any link clicked inside the DIV to reload in that same DIV, similar to an iframe, but obviously without using an iframe, due to it's compatibility issues. Is this possible by editing the above code? If not what do I need? Thanks in advance for any help! I was under the impression that you can always access any element on a webpage very easily by assigning a value to the "id" attribute. It seems this is true in the Chrome browser but not in the Opera Browser. My God I can't believe how much disarray the state of programming is in when it comes to certain things working in certain browsers...What's the HTML5 standard on this situation...in other words what does the ECMAScript standard say is the proper implementation?

Should you be able to access any webpage element by simply specifying the value of it's 'id' attribute? Chrome says 'yes'. Opera says 'no can do'. I get a 'Uncaught Exception;ReferenceError:Undefined variable' error message in the Opera debugger window. The exact same .html document throws no exceptions in the Chrome(version 18) browser. |
