Prevent Loading Images Before Executing The Script?
Aug 19, 2010
I'm using mooflow code on my website, problem is that it shows images on top of one another, before script arranges them to row. This only happens with explorer.
You can see example of the images popping up (and scroll bar flashing on the side of the page), when this page is loading on explorer, [URL]
Could there be some solution for the explorer so it wouldn't load images before executing the script? Other browsers work better with the loading order.
for the last day and a half i've been attempting to prevent images on a page from loading. i do this by calling a domready function. i just need this to work in firefox, so i'm using its DOMContentLoaded event. however, for troubleshooting purposes i have opted off the domready stuff and simply placed my code at the bottom of the html before the closing body tag, which does the same. my research shows that all the lazyloading techniques (which at the core are similar to what i'm doing; ie, preventing an image from loading) that do not rely on creating a custom attribute for the img tag, do not work. jquery's lazyloading plugin does not work: [URL] mootools' lazyloading plugin does not work: [URL]. however, they must have worked at one point. read the latest comments on lazyloading techniques online and you'll see that mostly everyone suddenly is unable to achieve lazyloading on their site. the only effect one achieves is that the image fades in when scrolling down, however it has already been downloaded when the page rendered, but it should only have been downloaded from the server once the scroll threshold for that image is hit.
calling a function to replace images with small placeholder images immediately after the dom loads (ie, before the full page loads) should work. this should prevent the loading of the original file in the src attribute, but it does not. i'm using firefox 3.6.3, but it happens on webkit browsers as well (though this is a documented bug); opera, however, works as it should. i did my research pretty thoroughly, but if i missed something
I have a select dropdown and 5 text fields. based on the option selected (which are the units - cm/mm/inches/ft/yard etc), i change the values in the text fields using javascript to the corresponding units.
my problem is that when the options are selected very quickly(for eg using the keyboard's up/down keys) then quickly, the text field values lose their connection with the select box and the values become illegal.
I suspect that the javascript function is being called even before the earlier execution has not terminated. I tried using a global variable and using it as a lock, but still no success.
Is there some way from preventing the JavaScript code in a document loaded into an iframe from executing? I don't have access to the pages being loaded into the i-frame so I can't modify then. They are being loaded from a server.
I've run into a roadblock I just can't seem to get past. I'm developing a website for work (internal) and I have a lot of javascript calculations going on when someone enters data. What I want to do is to have a div apear when it begins calculating and goes away when it ends. I'm using:
// CSS code div.loading-invisible{ display: none; } div.loading-visible { display: block; ... various formatting here ... } // Javascript function calculate(evalForm) { document.getElementById("loading").className = "loading-visible"; [Code]...
It works great in firefox. The div display appropriately, calculates, then disappears when it's finished. However, in IE it seems to want to calculate everything before anything is displayed. I placed alerts in the code to be able to pause it mid way and it worked. But without alerts it just hangs while everything is being calculated and the code for the loading screen just seems to cancel itself out. I attempted to put some waits in the code such as:
I am trying to load image and display other stuff dynamically, but I am having a hard time with it.How can I find out "span class" on the code below?what exactly defines "this"? and how can I access its contents?
I'm having a problem with a script on my website. My website is wordpress based. I have this script that i need to load on every page except on the main page.
I have tried to make it work, but the only way i can get it to work like i need is including it on the main page as well.
Is there any way i can prevent the script to load on the main page, but load on the other pages?
I mean, is there any code to block javascript on a particular page of a website, but still work on the other pages?
I would to know please if is it possible to block the loading of particular site by/via javascript. Having a web page with a flash content that contains a call to a particular site, I don't want to receive information from that site. does exists a javascript code that block that call to that site?
Is there any method which blocks the website from loading, if the browser using is not java script enabled? I have a webpage with some details to be entered. This website is designed in such a way that it checks the exceptions in the entry and alerts the user regarding it which is done using javascript. but for some users this feature is not working. I guess its the problem with the browser they use. So how can I alert them to enable Java by adding something to the script? Is there any way which prevents the page from loading if java is not enabled in the browser?
I'm having difficulty loading images via Ajax on a site that I've been working on.I'm performing the ajax by using the Request.HTML object of the MooTools framework. Basically, I'm just passing some parameters to a php script which outputs some image tags and then I insert that HTML into a pre-defined content div. For some reason though, it seems that big images don't seem to load consistently when using this technique. Usually, they will just show up as broken images, but when I navigate to the url of the image that is 'broken', it displays just fine. Also, occasionally after navigating to the actual url of the image, my browser will cache the image and then it will display just fine when loading it through Ajax.
I have a site where the header, footer, menu and Google map remain present on most pages,but the copy in the main paragraph changes depending on which menu option is selected.The above is achieved using PHP includes and query strings.I'm using jQuery to 'fade in' the main body text when a page loads, and 'fade out' the text when a menu link is clicked on. It just looks nice, because all the stuff that is always present stays in place (I guess the browser caches it?) and just the main body text fades out and the new fades in.The thing is, the 'fade out' that is triggered by the 'click' event (on the menu link) tends to be interrupted by the browser moving on to the new page. I just want to the browser to stay for half a second so that the nice fade finishes properly. Ironically, when my connection is interrupted or the new page loads slowly, it looks at its best because the fade has time to finish
I've gotten .load to load content into a div but if the window is not at the top of the page it scrolls back to the top each time the new content is loaded but I wanted to avoid any sort of change on the page other than the content in the div. It seems pointless if the user has to scroll back down to the div where the content is each time? code...
Is there a way to keep the window in the same position? Also while I'm at it - is there a more efficient way to write this considering I have 9 pages or should I just write this code out for each instance?
It's for a photo gallery like this http:[url].....php but the one I need it for has 100 images so the page loads much slower. I can't just put the loading gif behind the images (as you would normaly) because you can see it with each image fade in and out. how I can have a loading gif show "only" while the images are initially loading, and then it goes away?
I am trying to load an image into a div using AJAX.Instead on loading the image, I get PNG as the result in the div.Does anyone know how to load an image into a div?
function pre_load_pics() { if (document.images) { var image1 = new Image(400,265); image1.scr = "pic1.jpg"; var image2 = new Image(400,265); image2.scr = "pic2.jpg";
etc etc
}
and the following in the body
<script> pre_load_pics(); </script>
but images are not downloaded until the app needs them later. Something wrong ? I thought they should be downloaded earlier?
I feel like a complete fool! I should know the answer to the Q:
How do I load an image with JS and replace the default image?
Some background: My final objective is to have a web site where it is VERY difficult to copy images off the site. The first thing I was going to do was force folks to turn on JavaScript so that I could disable the right click pop up menu. To force this, I thought I would have all the default images say that JavaScript is required to view the images. The problem is that I cannot figure out for the world in me how to load the good image.......
I am currently using the scrollable jquery plugin to scroll some images of thumbnails in a gallery. What I'm trying to do now, is figure out how to load the large version of those thumbnails into a div when they are clicked.
Here is a link to the webpage where the source can be viewed. [URL]
I want to pre-load images for my gallery, but I'm not sure of the best way to go about it. Currently, I have php code that generates thumbnail images on page load and while this works fine, it at times can be very time consuming. For reference, below is my php code. how I could/should pre-load images?
I have some rollover images on my website, and they don't switch until the page is finished loading.Is this standard? Is there a way to have the rollovers work when the page is still in the process of loading all the images?
In my website I constructed a script that changes the image.sources of several images. The changes are made by calling a JS-function. The function is invoked by selecting an option in an html-form. In my second post below I pasted the code.
The problem is that each time the images are changed the browser starts to load them all again, although all images were PRELOADED in the <head> section of my HTML page. It takes time every time a user invokes image changings, and also the visual effects are worsened. How can I prevent the browser from loading the images again each time?
I am using Lightbox v2.04 with ASP.Net 2008. The issue i am finding is that the images that are controlled by the java script are not loading if the page is in a sub folder. I have my main folder that contains a folder for my java script folder, a folder for my images, and a folder that contains some pages.
This is the code in the lightbox.js file that i believe may be the cause.
I would like to display a different set of images each time a person visits a web site. I have seen this done in many banner advertisments and product photos. Can someone tell me how this can be done with Javascript?
I have php script that reads an image from database and outputs it.If i send request via AJAX i get the "inside" of the image into responseText, how to output it to a browser.so i can see an image instead an text?
