I have a PHP page that talks to a MySQL page, i want to put in a "loading" message. I have tied to use a layer and using a showlayer at the top of the page and hide at the bottom, but it does not work, it still waits for the PHP to run. I know it can be done, as i have seen it, how do they do that?
http:[url].....If you're on fast internet, you might not even see it, but I don't know how they do two things upon entrance.
1.) Allow the content to load (and function as a preloader)
2.) Get everything to fade in after loader completes. Is it just a div overlapping everything where opacity turns from 1 to 0 or what?
I know this loader must be javascript, but this is all I can find when viewing the source, so I don't know if there is php involved but I'm guessing there is.
I have a small function that replaces an image with that of a clicked thumbnail (and updates some text). Is it possible to display a loader whilst the new image is being downloaded?code...
This is a script that will load a page with a random background song, plus will refresh the page when the song finishes!
<script language="javascript"> // use this script freely // var numsong stands for the number of songs given var nummidi = 5 day = new Date() seed = day.getTime() ran = parseInt(((seed - (parseInt(seed/1000,10) * 1000))/10)/100*numsong + 1,10) if (ran == (5)) { song=("song source") words=("song name") time=("song time in seconds") } else if (ran == (4)) { song=("song source") words=("song name") time=("song time in seconds") } else if (ran == (3)) { song=("song source") words=("song name") time=("song time in seconds") } else if (ran == (2)) { song=("song source") words=("song name") time=("song time in seconds") } else if (ran == (1)) { song=("song source") words=("song name") time=("song time in seconds") } document.write('<meta http-equiv="refresh" content="' + time + ' URL=npmusic.html">') document.write('<EMBED SRC= "' + song + '" CONTROLS=smallconsole HEIGHT=45 WIDTH=290 AUTOSTART=TRUE LOOP=FALSE VOLUME=100%>') document.write('<br>You are listening to ' + words + ' ') </SCRIPT>
This script was made for a small pop-up window to have nothing but the song file in it. Also, you use this script in the <body> of the file. (Yes, the meta tag works there) ...
I'm creating a site using AJAX and I would like for an ajax loader to appear in between the page loadings. $("#menu ul li").click(function(event) { $("#ajaxLoader").show(function(){ alert('hello'); }); setTimeout("jQuery.fn.test("about");", 3000); });}); jQuery.fn.test = function(page) { $("#content").load(page + ".html"); $("#ajaxLoader").hide(function(){ alert('good bye'); });}; This works perfectly the first time - the ajax loader appears for about three seconds before disappearing and instead the page is displayed. But the second, third, fourth ... time, the ajax loader never shows up.
I want to make a gallery with image loader. When image placed in JavaScript Image object finishes loading, the script includes it into HTML code and performs jQuery fadeIn effect on it.
The '.complete' property of the Java Script 'Image' object is perfect for this purpose(recognizing when image has finished loading) but the only problem is that Mozilla Firefox doesn't recognize this property and in this browser it's always true(always loaded) even if it's not. The script works perfectly in other browsers.
Does someone of you know what is the other way of recognizing whether the image finished loading or not?
Does anyone know how to add an ajax loader to the remember the milk validation example? So that while the backend is busy, it shows the gif, when it's finished, it hides the gif...
I want to start coding using the YUI provided by yahoo, but do not understand how to set up the yui.loader script that pulls in the rest for me. What this script does is pull in all dependencies and install them. Just like using the installer in linux. But there does not seem to be any howtos for beginners. I have never used jaascript before, And this is suppsed to be a cut & paste way of getting started but I have been doing that most of the day and reading about it but I still obvoisly do not understand or missing somthing.
I'm working on a php/jQuery application, I want to display a loading image automatically every ajax request, without writing code for every ajax request. Is there anyway to do this.
I am having a little problem trying to show a loader (An animated GIF) while some request to a database happens. I have a page where the user selects a YEAR and when they select it with AJAX I perform a request to a database to get all the values for that specific year.
The problem is that there is a lot of information (4000+ records) that I need to query and show in a table (Actually I didn't use a table I use DIVs that look like a table), and when the user selects the year the webpage freezes for about 5 seconds and then it loads all of the data.
Is there a way to sort of show an image loader gif while the data is being gotten? I tried putting the loader image in the DIV container while no year is selected and then once the request is done, I substitute the DIV container's contents (The image loader) for the data from the database.
how to do a custom lazy load ???You know for instance... lets say I got 500,000 images to load on a page... it's inside a dive... well I want to load the images when it's needed.So not all 500,000 images will load all at once. I want like 10 to load at a time.. this will make the div scrollable.so when the user scrolls down to the 8th image it will load 10 more images and so on.
how to make their own function like this?how do you detect if the user scrolled to the 8th image? I am pretty sure I can use a function.... that will send variables to a php script that will use the mysql limit. The javascript would send a value which is where to start loading from the 10th image in the database.. meaning start grabbing the images from the 11th image onward for a max of 10 total images to display.
I am brand new to JQuery but love it already. I have a couple of questions about a image effect I have found on a site and have used in my website. I found it herehttp://www.htmldrive.net/items/show/136/Image-Preview-Gallery and you can see how I am using it [URL]... The problem I have is. Is there anyway to add a per-loader into the jquery while theimage loads as the images I am using are larger then what the person that made used and the images are taking a little while to load. and also when you click the image it takes you to a new page with just the image on it is there a way to stop it from doing that?
I'm working on some code and am running into brick walls. I'm trying to write out Javascript with Javascript and I've read the clj Meta FAQ and didn't see the answer, read many similar posts (with no luck though), and searched through the IRT.ORG Faqs (www.irt.org/script/script.htm).
The Javascript is designed to open an popup window and then inside that window call another script which will resize that window. There may be another way around this but the reason I tried this approach initially was that I wanted to call the onload handler in the popup window to resize the image only after the image had completely loaded. I've had some code in the primary Javascript file (showimage.js) before that works if the image has been cached but on the first load, it doesn't resize properly which tells me it is probably because it is trying to resize the window based on the image size but it isn't completely known at that point. So I removed that code and tried placing the resizing code in the second Javascript file (resizewindow.js). BTW I've tried other code to open a popup image and automatically size it ie Q1443 at irt.org but that doesn't do exactly what we need.
Even if there is another way to do this with one file, I still want to figure out why this isn't working in case I run into it in the future.
I thought what I would need to do to use document.writeln to write Javascript would be to escape any special characters and to break apart the script tag ie
document.writeln('</SCRIPT>');
would become
document.writeln('</SCR' + 'IPT>');
I have a HTML page and 2 Javascript files. All files are in the same directory and have permissions set correctly.
Here are the 3 files (keep in mind wordwrap has jacked up the formatting):
index.html ---------- <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Test</title> <SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1" SRC="showimage.js"> </SCRIPT> </head>
<body> Click the house<BR> <A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG SRC="house1thumb.jpg"></A> </body> </html>
showimage.js ------------ function newWindow1(pic,sitename) {
resizewindow.js --------------- function resizewindow() { // Do resizing here. // Right now this isn't being executed alert("resizing window"); }
Can anyone provide some pointers as to why this javascript is failing? I'm using IE6 on Win2k and when I click on the image to open the popup window, it does open the window but it is white with no content and the system immediately goes from about 4% CPU usage to 100% and consistently stays there until I kill that window with the task manager.
Attached is a simple HTML file that adds and delete rows. In the add row function I set an attribute "onClick" this triggers the testMessage() function. When I try this in Firefox it works just fine however on IE it just refuses to work.
What is interseting is the ROW that already exists has a similar 'onClick' event which works when the page is loaded, but subsequent "row" additions to the table to not work in IE. Code:
I'm getting errors in Firefox everytime I try to run this frame resize code, but it works fine in IE. I can't seem to figure out what the problem is with it.
The error is: Error: theFrame has no properties Line: 8
The line that the javascript console is showing an error for is in italics.
I'm already past the basics of Javascript, and i need something that takes me to the other level and teaches me the new technologies and cool stuff (drag&drop, AJAX, OOP in javascript, maybe XUL...etc). So far i found these two books:
1. Sitepoint's "The JavaScript Anthology: 101 Essential Tips, Tricks & Hacks". 2. Worx's "Professional JavaScript for Web Developers (Wrox Professional Guides)"
Both seems to cover very insteresting topics, but i can only buy one of them. So which one do you suggest?
and by the way, i've read the sample chapter 5 of Sitepoint's book, and it seems like the author(s) just put the solutions/codes there and let you figure them out on your own. Is this how the rest of the chapters are?
This is a question about defensive web browsing. Ocassionally I run into a page whose JavaScript does something that I find obnoxious. I would like to turn off JavaScript only for that page (instead of disabling it globally). It would be cool if there were some way to do this through a "bookmarkable" JavaScript snippet using the javascript: pseudoprotocol. Does anyone know any trick to do any of this?
I am looking for a method to extract the links embedded within the Javascript in a web page: an ActiveX component, or example code in C++/Pascal/etc. I am looking for a general solution, not one tailored to a particular page/script.
Hopefully, the problem can be solved without recreating a complete Javascript interpreter. Any ideas?
I have some javascript that I have written into the <body> section and it works great. But I would like to make it into a javascript function and define the function in the <head> section. Then in the <body> section write a small bit of javascript that would call the function() object. Code:
I would like to know how to write javascript such that, a part of it isnt considered as script, & rather as HTML. Code:
Ok, the layer div can be written using document.write. But, Google ad itself is a javascript isnt it. How can it be written into this? How does this work?
Ok so, this is my purpose: - to be able to load asynchronously (via AJAX) some javascript ads (like google's or adbrite) so as to make them be loaded in the background, then update the page after the ads have loaded via innerHTML
Why? -Because 90% of the time in my newer sites, javascript ads are the major offender in terms of speed of page rendering
My problem: Via ajax, I can call a php file that retrieves some javascript and outputs it, XMLhttprequest returns those javascript lines, but they don't render in the page, since they miss the whole page loading, and are apparently not parsed For example, let's say I call a php file via ajax, and it returns the output into a variable named "text" containing "document.write('hello')" if I use xxx.innerHTML=text, nothing happens
My 1st solution: Passing those javascript lines to eval() [like eval(text) ], but this produces a second problem, that I couldn't solve (probably because of my lack of knowledge in javascipt): if I eval the code, it deletes my current page and renders a new one for example, if I parse a document.write, my page disappears, and a new one is rendered with the document.write text
What I want is basically to make that "document.write" appear inside a div in my page, adding to the content (and not overwriting the whole page), much like what happens when using innerHTML
Is this even possible? How would you go about it? I tried xxx.innerHTML=eval(outputfromphpfile) but it overwrites my whole page...
