I have long html/CSS (no CMS or php, etc.) web pages. Some people run away when they see too much content on a page. So I hide the large lower section of the pages and have the user click anchor text to execute simple JS code to change the display from 'none' to 'block' or back to re-hide.
Code:
(BTW my research indicates that search engines do not know the difference between display='none' and normal content, or I would not be hiding content in the first place.)
Within this hidden content, I have anchor text to provide name handles
Code:
So users can click a link and go directly to that section. Within that link I include
Code:
So that works fine within a particular page. But when I want to link to an anchor on another page which is within this hidden content, the browser cannot display the anchor text because it is still hidden.
Is there a way to execute the JS code to change the DOM, changing the display to 'block' on the content of the new page?
I do not see how, because the new page isn't loaded yet, there is no DOM within the browser yet, so how can it be manipulated?
Of course if I was using php I could generate the code with the property set as desired. But for straight up html/CSS/JS pages is this possible?
I get the feeling I am missing something simple here, either a simple solution or the simple fact that this is just an inherent limitation of html.
Can I intercept the loading of an image BEFORE it loads? We're looking at using an img tag for inserting stats on our server. Here's what I'm considering.
1) Collect certain information server side, write an img to the document like so (note the URL vars): <img id="statsImg" src="stats.cfm?somevar=someval" width="1" height="1" />
2) Using JS, intercept the load of this image BEFORE it takes place, and add things to the URL vars. This way, if JS is not present, you get the default stuff, but if JS is present, you get extra stuff.
What I'm trying to do is execute a functions when the body loads. This function will make an XMLHttpRequest and then recals itself every 2 minutes for example. The good thing is it really recals itself every 2 minutes, but it doesn't make any changes. The XMLHttpRequest is a request to an XML file on the internet which changes often, and I want the data of it. When my function recals itself, it displays the data of the first call and never changes after that. So I guess it never makes a new XMLHttpRequest, or it doesn't update the returned data.
I have been trying to work my way around this issue for some time now. I am trying to stop a marquee from scrolling as soon as the page start to load not after. I have been using this to pause the marquee with JavaScript but the command does not execute but after the page loads; after all the html loads.
With this code the marquee does stop but after the page loads completely so as the page loads the marquee start to scroll and then stops as soon as the page finishes loading but with the first image of the marquee have way out. I need to be able to load the marquee 100% stopped as the page loads so then I can use the buttons I placed to control the marquee.
My question is:
Is there ANY way to completely stop the marquee from scrolling as soon as the page loads??
how to scroll the marquee by click; meaning by every click of the mouse the marquee moves either left or right, would be even better. p.s: Noted that this code does NOT work in FF for some reason. The stop does not work and the buttons don't respond. why in FF they don't work but in GC and IE they do?
I have a form within an iframe that I want to use to refresh the location of the parent. I am using the form to set session variables that are used within the parent. So in the iframe I have:
<form name="MyForm" method="POST" action="<?php echo $_SERVER['PHP_SELF'] . '?' . SID; ?>"> And to submit this form I'm using this link:
<a href="javascript: submitform()">Search</a> Which refers to this script:
<SCRIPT LANGUAGE="JavaScript"> <!-- function loadParent() { parent.location.href = "/search_results.php?"; }
function submitform() { document.MyForm.submit(); loadParent(); } //--> </SCRIPT>
(I think!) my problem is this; it works fine if the MyForm action, i.e. ="<?php echo $_SERVER['PHP_SELF'] . '?' . SID; ?>", completes before loadParent() is executed but if there is a slight delay in the time it takes for the server to do this, loadParent() is executed too early and the input from MyForm is lost.
What I need is to tell the script to wait until the MyForm action has completed, i.e. the page has refreshed, before running loadParent(). I'm sure there are loads of different ways of doing this. Ideally I would like something that detects the page refresh within the iframe (caused by the MyForm action) and not something that relies on a timed delay loop.
I have a slide show program. First theres stuff to set up the array, and the time between slides Then a function startIt()is defined then a function stopIt() Then two buttons, Start and Stop, which when pressed call the relevant functions.
When the page loads, you have to click the Start button to get the slide show running, but I'd like it to start running straight away without having to click. I can't for the life of me figure this out. I thought it was just a question of putting the line startIt(); Code:
I'm having probs with append(). When the page loads I add a function to certain images:
But after appending a now row, with a similar image, the onclick function on that row doesnt work, seems like it needs to be reinitialized or something.
I tried making a function of:
But when I call that function after appending, the new image is not clickable and the images that were already there, get an extra function on click.
I've ran into a little problem when using resize() function in jQuery as I am trying to call a function after the document loads and later on should window resize occur, but I can't really figure out use jQuery syntax to do the both at the same time within a function.
Here's a example: $(document).ready(function() { doScript(); $(window).resize(function doScript() { // do stuff }); }); So it is possible to give an instance name to this (resize) function and call it just once after the page loads?
It seems like when I load javascript code into a page, that each item I add, such as an accordian vertical navbar, image slider, etc, that each time I add one, the page loads a second or so slower with each one added. I would like some of these features, but is this just a part of life, or are there tricks to avoid the slower load time? It is not major time but after the 2 items I mentioned, it added on about 2 seconds.
I read that $(document).ready(function() might slow me down but I do not see that statement in any of my .js files.
i have an html page that when it loads theres an onLoad event called which calls a function.now what i want to do is be able to click a link that refreshes the page but at the time on the refresh it skips the onLoad event. is this possible?
The function is called from a child popup window which closes the child when called. The function works well however when the child window is closed the cursor on the parent window continues as if it is trying and load something (although nothing is being loaded). Do I need some sort of end function to close the function off after it is executed?
I've been looking all over for an explanation of this function declaration but cant find it. what it means to have a function with no name, just declared as this. When does it execute? How does it get called?
I need to execute a function after a link to a section within the same document has been clicked and the navigation has occurred. When using the onclick event handler the JS function is executed before the navigation occurs. I can't tie it to a window.onload event since the link only navigates within the already loaded document.
I'm not having any luck searching due to not knowing what keywords to use. I looked at an explanation of bubbling vs capturing, but that doesn't appear to be what I need.
Just posted this thread a few mins ago and for some reason it got deleted? Maybe it was because of the URL shortening I used. Anyway here is an example of what I mean
I have this code which removes a class from an item on mouse out.
Code:
function mouseOut8( ) { $('.bar8') .removeClass("barover"); }
I would like to change this so that the class is removed from the item I have just moused out of instead of specifying the exact item. This is so I can use this function for multiple items. I tried replacing the '.bar8' with 'this' but it didn't work.
I have a javascript code which makes a word toggle links under it. For example: Before clicking on it it looks like this: Stories: then once its clicked on it looks like: Stories: story 1 story 2 story 3
How can I make it so when you click stories it creates that list and also goes to story 1. Here is the code I have: Code: <h2 style="margin-left : 25px;"><img src="/images/sort_ASC.gif" id="img_DegreeList5" alt="" /> <a href="javascript:toggleDegreeList(5);" style="color:#336699;">Teaching Tales</a></a></h2> <div id="DegreeList5" style="display:none;"> <ul><ul> <li><a href="teaching_tales1.php">Story 1</a></li> <li><a href="teaching_tales2.php">Story 2</a></li> </ul></ul> </div>
And here is the toggledegree script Code: <script type="text/javascript"> var currentDegreeList = null; function toggleDegreeList(which) { if(currentDegreeList) { document.getElementById('DegreeList'+currentDegreeList).style.display = 'none'; document.getElementById('img_DegreeList'+currentDegreeList).src = '/images/sort_ASC.gif'; } if(currentDegreeList != which) { document.getElementById('DegreeList'+which).style.display = 'block'; document.getElementById('img_DegreeList'+which).src = '/images/sort_DESC.gif'; currentDegreeList = which; } else { currentDegreeList = null; } } var submitted = false; function submitForm() { var val = (submitted) ? false : true; submitted = true; return val; } </script>
If you actually want to see the live page its here [URL].
I want to execute a javascript function when ever the user clicks the window's close button, means before closing the window I should be able to execute my function.
$("#scroll").hover(function(){ $(this).find(".front").stop().animate({ top:"184px"},500,function(){ $(this).find(".front").stop().animate({ top : "7px"}, 300); }); });
I try to make a scrolling picture. when mouse roll over the image with .front class will scroll down, but it has to come back after mouse roll out. the scroll down is working but I wrote a callback function, but it doesn't work.
html part <div id="scroll"> <a href="../images/big_html/babytracker_b.png"> <img src="../images/thumb_html/jukebox.jpg" /> <img src="../images/thumb_html/Tracker.jpg" class="front"/> </a> </div>
We're trying to enhance and optimize the forms in our projects with jQuery, but I don't know if something we want is possible. Nowadays we are using simple javascript to enable and disable elements in our forms, we have a part to execute when the document is loaded and another that is executed with the interaction of the user.
For example, we have a simple select with "Race" : "Caucassian", "African" and "Other", when the user selects something we enable or disable a textfield (where the user specifies the other race) depending of the election; and when the user saves the data and reopen the form to modify the elements, we execute a function that evaluates the value of the select (previously loaded from the database) and enable or disable the textfield.
We need to optimize this because we've got really large forms (sometimes with 400 different fields) and it would be great to do this in 1 step and have one file with the behaviours instead of doing this once for the interaction and once for the reload. I've been thinking in a way for subscribing to the onchange and execute it at the same time, but I don't know if there's any way of doing that...
I have a select form with id=px. I want to make the select execute a function every time an option is selected. I took the Change function and my code looks like this:
$("#px").change(function () { var str = ""; $("#px option:selected").each(function () { str += $(this).text() + " "; }); // $("div").text(str); - this line is changed with my function $('#selectable1 span.cica').css('font-size', str + "px"); }) .change();
It looks that srt variable is not working with my .css function. What is wrong? My markup is: <select id="px"> <option class="option" value="8" label="8">8</option> <option class="option" value="9" label="9">9</option> <option class="option" value="10" label="10">10</option> <option class="option" value="11" label="11">11</option> <option class="option" value="12" label="12">12</option> <option class="option" value="14" label="14">14</option> <option class="option" value="18" label="18">18</option> <option class="option" value="21" label="21">21</option> <option class="option" value="24" label="24">24</option> <option class="option" value="36" label="36">36</option> <option class="option" value="48" label="48">48</option> <option class="option" value="60" label="60">60</option> <option class="option" value="72" label="72">72</option> </select>
I'm trying to execute a simple JSON request using getJSON but I can't get a successful response. My code is below. If I run this I always receive an error. If I add "callback?" (making it JSONP) then I can see the correct results in Firebug but the call back function is never executed. function getResults(url) { var gptUrl = "[URL]"; $.getJSON(url, {f: "json"}, function() { alert("success"); }) .success(function() { alert("second success"); }) .error(function() { alert("error"); }) .complete(function() { alert("complete"); });}
