Browser Slow To Change State Of Elements When Style Changed To Hidden
Jan 17, 2006
'When my form is submitted, I have onsubmit pointed to the following
code snippet. But, the button is not actually set to disabled and the
style.visibility changes are not made for several seconds. It appears
that it goes into validateForm and doing the rest of this snippet
before the browser makes the changes.
How can I get the browser to immediately make the UI change?
function submitForm(servleturl) {
var submitbuttonelem = document.getElementById("submit");
submitbuttonelem.disabled = true;
document.getElementById("modgradeform").style.visibility="hidden";
var mydiv = document.getElementById("contentarea");
mydiv.innerHTML = "Validating the form.";
mydiv.style.visibility="visible";
var ret = validateForm();
I've created a checkbox and radio button replacement plugin (URL...), and I'm trying to be as thorough as possible.One situation that I have yet to solve is if a button is given the attribute checked="checked" through some external function. I'm not sure of how to detect this event so that the replacement image is also updated. The .change() method only works when the user actually clicks on the button.The reason I am trying to work this out is because I am adding support for disabled buttons as well. From what I've seen, there are plenty of situations where a button is disabled until a user either selects something else, or fills in required info, etc., and then it is enabled (most likely through the removal of disabled= 'disabled '). If the developer has already worked that in, I don't want the implementation of my plugin to affect that. It should just work automatically.I do check the states on page load, but i'm not running any sort of loop to constantly look for changes.
Specifically, assume I have a div tag of absolute dimensions. I need to figure out, first, whether or not the text inside the div tag is partially hidden by the overflow setting, and if so, what the hidden text is.
Is this even possible? Obviously, the rendering engine in the browser "knows" this information, but is it accessible through Javascript?
There is a live search on my web page but the box of available options which falls below the 'input' field has a transparent background color. How can it be changed to non-transparent?This line below makes the background white, but all the text on the page shines through, since the default is transparent.
So I have a table. With jquery I change border properties of several td. If later on in the code those same td have their background color changed by jquery, their borders return back.
Even if nothing is changed, nevertheless after some time some of the borders would seemingly randomly suddenly show up. I am working on a maze so this really spoils the game.
Is there a generic way to fire an event when the state/value of a checkbox is changed by another event - i.e. not a user action. In this scenario, I have a set of checkboxes with a "select all" checkbox. I have the code written such that checking or unchecking the "select all" checkbox updates the state of all of the checkboxes below.
The extra requirement here is that some of these checkboxes have "children". So, when you check one of these, its children are automatically checked as well. So, what I need to do is check the main "select all" checkbox, which would then check all of the immediate children, which would then check all of their immediate children. I tried both an onchange and onclick event, but neither seem to be firing.
What I want to do is have the div appear as if it is sliding in, instead of just appearing (similar to WindowsXP effect). If this isn't possible, is it possible to just "slide" the content that's below the div down by setting the height of the div to 0, set it to display but not visible, and then use js to gradually increase it's height, and then display?
I've managed to use ajax to fetch and display the quotations which associate to a particular rep after i click that rep's name. But the only problem is the speed of response. The first few clicks are ok and very smooth. But after several tries, the response become slow and I cant even scroll down the webpage, and later on the web browser craches....
here it is:
<!-- Data display area --> <br /><input type="image" id="printbtn" value="Print" src="images/printer.png"/><br /> <div id="container">
I'm having trouble using jQuery to find get select box values by element name. At the moment the code is in a for loop and it gets 8 different form values and puts it into an array. Currently this takes 1.5 seconds to execute which is far too slow as the user has to wait for it to finish. Here's the code which is inside the loop:
[Code]...
This when run executes instantly with no time delay. Why is the jQuery way so much slower? I'm all for saving 2 lines of code but not when it's 10x slower. Also I shouldn't need to put an id on the select box element to make finding it faster, the name value is already unique because I require the specific value once the form has been submitted.
I am trying to save the state of visibility (hidden or visible) of a portlet as a variable so that It can be saved. Hopefully allowing the user to return to the page without having to toggle portlets open/close again.
My issue: Unable to correctly establish whether or not the clicked portlet is visible or hidden while assigning a variable to be used as post data to a database.
Here is the code so far
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html lang="en"> <head>
Hereyou can find the whole example. By clicking onClick to Addyou will clone 100 times the elementtrackOn; then it will be append to the tabletracklistOn. Unfortunatly, if these elements are inside aformyou can see that the time is very high before the process is finish.If I remove the form, is quite immediate. Why this behaviour? How can I fix this problem? P.S. I don't know why, but I can't paste the whole code here. So follow the jsFiddle link please :)
I have a form with many fields... the fields are getting values from a database.
I've tried onunload to just submit the form regardless of changes or not but onunload and submit isn't working for me. Now I need some type of event that will fire when a user tries to navigate from a page to check to see if anything has changed and if so prompt them (confirmation) to take action or not.
I know that the reset button only takes away anything that was added to fields after the load so there must be some way to use the logic of reset to simply check to see if fields have changed, right?
I recently updated from jQuery 1.4 (I think 1.4.4) to 1.5.1. Before the upgrade, when users pressed the browser's Back button, they would usually be taken back to a page with all their changes intact. If they had modified input values or clicked objects that caused other parts of the page to change, they would still see those changes. Back literally took them back to the exact thing they were looking at before. Under 1.5.1, Back takes them to the prior page as it was when it first loaded. What changed? Can I get the old behavior back?
i need to change color of those patterns only or show as if it is changed in screenis it possible using jqueryImage can be divided in to 2 color separate images
I've noticed that the change event isn't fired on a text input when it's value is changed by JavaScript. It fires just fine when I type in the input and then lose focus. Example:
How do I change the background colour of an input box in a form as soon as the value is changed? Also the background should revert back to it's original colour if the user decides that they do not want to make any changes and hence retype back the orginial value.
I do not want the background to change after the user has moved to the next form field but as soon as the value has been changed.
I have a pop-up window system on my site that shows an absolutely-positioned div over the entire page as a "pop up" of sorts when someone clicks a link. I use this simple line of Javascript to disable page scrolling when a "pop up" box is opened by a user:
The problem is that when a user is scrolled down on a page and clicks a link to bring up one of my pop up boxes, when the overflow is set to 'hidden' to disable scrolling, the page "jolts" back up to the top (similar as to what would happen if someone clicked an <a> element with href="#" ). However, the links are not actually links, but span tags that are programmed with JS to trigger the scrollbar to be disabled when clicked, so that is not the culprit here. I've narrowed the problem down to that one line of code which I posted earlier. Apparently, setting the documentElement overflow style to 'hidden' scrolls the user to the top of the page automatically along with "disabling" the scroll bar on the page.
I am wondering if there is a way to prevent this jolting to the top of the page each time that JS code is triggered. I don't want users to have to scroll back down to where they were each time they open a pop up dialogue box on my site, as this would be detrimental for usability purposes.
I have 6 horizontal navigation image links on top of my site. The regular images are black n white, but on the hover they transform to a colored image. Each image leads to a different page on my site, I'm wondering if I can make the image corresponding to that page light up whenever on that page.
Here is an example of what is done so far: [URL]. When you mouse over the b&w images you will see the image change to color. When you mouse over the links on the left they will have a rollover and also change the image on the right to color.
What I would also like is mouseover the image to change the rollover state of the link on the left. Here is my code so far.. PHP Code: <style type="text/css"><!--/* ================================= *//* ====== Subject Matter Rollovers ====== */#menuButton1{height: 41px;width: 133px; overflow: hidden;background: url(images/content/buttons/subjectmatter.png) top left no-repeat; display: block;text-decoration:none;line-height:2.5em;color:#000000;} #menuButton1:hover{color:#FFFF00;
I thought the following might work (2nd image) Code: document.getElementById('link2').class='menu_hover'; But as you see no it does not.
I want to use jquery to detect what type of browser you are using and display a link to a .wmv file if you are on IE or display a link to a .mp4 file if you are any other type of browser.I have this script declaration in my <head> section.
I use sprites for rollover effects so the hover attribute just changes the background image position. Everything works cool with the rollovers. What I would like to do, is make a text link that when rolled over will change a separate background image to it's hover state. I should add, that the the rollover image has it's own div and is separate from where the text link is located. To get a visual you can check the website [URL] In the body section I would like to make each of the dark red section titles a link that when rolled over will change the hover state of the corresponding "more" button.
I'm writing a reusable JavaScript library which needs to set certain styles in a document. The document may have an existing stylesheet definition either by a link or by an existing stylesheet declaration in the documents head section.
How can I use JavaScript to append my own style sheet information to a possibly already existing stylesheet definition?
