JavaScript - Speeding Up Loading Of File From Another Site
Hi,
I have a JS file on site A which needs a few parameters from a short text file on site B. Since crossing domain boundaries in JS is problematic, the way I do it is that the JS actually opens an intermediate PHP file on site A which redirects to the destination page in site B. Here's how it goes: The call is made through: Code: On SiteA.com/myfile.js
var theFile = getFile("intermediate.php");
var lines = theFile.split("\n");
var var1 = lines[1];
var var2 = lines[2];
var var3 = lines[3];
On SiteA.com/intermediate.php:
<?php
include("http://www.mySiteB.com/theTextFile.txt"); ?>
The problem is that this takes a long time. I would really like to speed this up. For example - I thought of using a direct IP address, so that there won't be any need a DNS server (using Code: include("http://123.45.67.89/~myUsername/mySiteB/theTextFile.txt");
) but this would expose me to hackers as it would make my Hostgator username visible. According to HG support the above format is the only way to access my subsite via direct IP. Any ideas on how to speed this up, either by bypassing DNS (but without exposing username) or by offering another way of reading data across sites? Suggestions for both JS and PHP files would be appreciated. I cannot set up a CDN here. This is really important for me! THANK YOU!!! Similar TutorialsSo, I have to rely on a third party external JS file to load into a site of mine. Problem is I have to have it (for ads), but once every blue moon the server fails to repond to the request (its down or unresponsive), and thus because the JS can't load, the site hangs. Is there a reliable js/ajax etc.. mechanism that I can use to set an allotted time and if the js isn't loaded, cancel the call or stop it so the page can load? Please advise. Caveats: I cannot host it, I cannot use php. Basically I was given a script call and I include it in the header of the page. I don't have alot of room to host, use various technologies etc.. other than what I am able to use without any backend/app scripting. Is there a way to tell Javascript to load data or a php file the re-direct to that page? Right now i have a script that will re-direct when a user comes to the page. It waits about 5 seconds to give it time. I wanted to know if there was a way to load it with JS or AJAX. Thanks for any help. Hey guys, I currently have a flash header .swf file as the header in my webpage. Problem is, it's 300 KB so it loads after everything else has already loaded, leaving a huge blank space where the .swf is suppossed to be until it finishes downloading. Is there a way I can tell my page to pre-load the .swf before everything else so that all elements in my page look like they load at the same? For example, with images I can do something like this: function MM_preloadImages() { //v3.0 var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array(); var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++) if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}} } then: <body onload="MM_preloadImages('images/search.jpg','images/contact.jpg','images/home.jpg')"> Is there something like this for .swf? Hello, I am looking for a way to select a file from a list and load it into a webpage. The page and the files are stored on a sd-card for off-line usage, I know that listing files remote dynamicly needs a scripting engine but since the sd-card is on the client side that is not possible, but I can make a list of those files when creating them. It is intended for a datalogger on a tractor-puller, I create csv files with a bash script on the logger and for off-line viewing I use a javascript charting engine which loads the csv file, the files have the creation date as filename and I can make (and maintain) a list of files when creating them. The plan is that the we can select another data set (run) from within the browser and show that one. I have setup an example at http://www.dlogger.deserver.nl/test/ If someone can help me out this year starts good! What I mean by this is how do you load an xml document that has been inputted as a string in a form. I would've assumed it was something like this, but this doesn't seem to be working. Code: <html>
<head>
<script type="text/javascript">
function loadXML(file) {
var moz = (typeof document.implementation.createDocument != 'undefined');
var ie = (typeof window.ActiveXObject != 'undefined');
var xmlDoc;
if (moz)
xmlDoc = document.implementation.createDocument("", "", null);
else if (ie)
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.load(file);
return xmlDoc;
}
</script>
</head>
<body>
<input type="text" name="input1" size="15"/>
<input type="button" value="LOADXML" loadXML(input1.value)"/>
</body>
</html>
Where 'input1' would be an xml file in the same folder. ok guys im going to be honest here, i know nothing about javascript. ive been learning php and even that gets confusing at times. my issue: i bought a script off someone(php site) and it has a .php file that using .js files he had no idea how to fix the issue so im hoping you guys can help me fix it. this one .php page includes another .php file and 2 other .js files. i dont want to go and post every single file as one of them is like 1200 lines (i have if you like to hunt for errors) is there some code i can add in to make it show where its getting an error? i know you can in php and mysql the page get stuck on Loading... on the .php file which is line 647: AJS.setHTML(AJS.$('load'), 'Loading...') AJS.js & ocNewFixed.php (Starting page) all files can be downloaded he http://uppit.com/1233dylkbrfu/help.rar (too long to fit into 20k characters) Help would be appreciated. im trying to onclick function on the button but in firebug it will say, function not defined, i even tried to do it with a internal script, but still it will not work. please help Code: <!DOCTYPE html>

Hi, I have some code that performs differently in Opera than it does in any other browser. So I have a stylesheet specifically for opera. Is there a way to do something like this, where I check the browser, and if it's not opera, then load the default sheet, otherwise load the opera-specific css? Code: <script>

As of this writing, that code seems to break my page, as if it doesn't like loading a sheet based on an if/else clause. Hi, I'm currently working on my portfolio website and would like to have information about my movie clips be retrieved from an XML document when a thumbnail is clicked. I am building my website in HTML and would like to retrieve the Xml using JavaScript. Any help would be appreciated. My XML is valid and structured as such: <?xml version="1.0" encoding="UTF-8"?> <work> <motion> <reel> <title id="Demo Reel 2009" project="Self Promotion" client="Self"> <![CDATA[This demo reel is primaraly a collection ......]]> </title> </reel> . . . . These are my initial variable definitions and readXML function in javascript: <script language="javascript"> var xmldom, workNode, motionNode, printNode, fineartNode, displayNode, titleNode; function readXMLDocument() { xmldom=createDocument(); xmldom.async=false; if (xmldom.parseError != 0) { alert("An error occurred: \nError Code " + xmldom.parseError.errorCode + "\n" + "Line: " + xmldom.parseError.line + "\n" + "Line Pos: " + xmldom.parseError.linepos + "\n" + "Reason: " + xmldom.parseError.reason); } else { alert("Document: " + xmldom.documentElement); alert("Root: " + xmldom.documentElement.tagName); alert("Child: " + xmldom.documentElement.firstChild.tagName); alert("Xml DOM: " + xmldom.xml); } xmldom.load("workinfo.xml"); workNode=xmldom.documentElement; motionNode=workNode.firstChild; printNode=motionNode.nextSibling; fineartNode=printNode.nextSibling; } . . . . A call to function revealText is called "onClick" of a thumbnail as such: <a href="videopages/reel.html" class="vid" target="video" onClick="revealText(0)"> This is function revealText: function revealText(x) { var title, project, client, info; readXMLDocument(); displayNode=motionNode.childNode[x]; titleNode=displayNode.firstChild; title=titleNode.getAttribute("id"); project=titleNode.getAttribute("project"); client=titleNode.getAttribute("client"); info=titleNode.getNodeValue(); titleSpan.innerHTML=title; projectSpan.innerHTML=project; clientSpan.innerHTML=client; infoSpan.innerHTML=info; } </script> and these are the spans they are written to: <span id="titleSpan" class="vidinfo"> <span id="projectSpan" class="vidinfo"> <span id="clientSpan" class="vidinfo"> <p id="infoSpan" class="content"> If you have read this far, I REALLLLY appreciate it. And any ideas as to what is wrong would help alot. How to detect if the user clicked cancel while uploading a file ? Is there an event for it?
I'm try to set up a webpge that will play a live flash video on the left-hand side(got that part working) and display one slide of a presentation(jpg) to the right of the video. I would like to be able to control when the slide image changes by having some js check a text file on my server. The text file could contain something as simple as "Slide1.jpg". I will manipulate the text file with some code I've already written. Is there some simple js code I can put in my page that will cause it to check the text file every 5 seconds, and if the content of the file has changed, to refresh the image on the page with the new image? I'm try to get away from the "clicking" sound that is caused by doing a simple refresh of an Iframe. I'm a complete novice at js, so any help would be appreciated. I'm also open to other solutions that would accomplish the same thing. Thanks, Mike Hello all, I have the following code to load a new html page into the 'new content' div once the user scrolls to the bottom of the page. It all works fine. No problems, except I would like it to pause for a moment whilst it is loading, and show a loading box div at the bottom of the screen as it loads the new content, just to give some positive feedback for the user. So the new div would sit in a fixed position at 'bottom:0px;' and have a loading image inside it. Is this easy to do? I am new to javascript so bear with me Code: alreadyloading = false;
nextpage = 2;
$(window).scroll(function() {
if($(window).scrollTop() + $(window).height() == $(document).height()) {
if (alreadyloading == false) {
var url = "page"+nextpage+".html";
alreadyloading = true;
$.post(url, function(data) {
$('#newcontent').children().last().after(data);
alreadyloading = false;
nextpage++;
});
}
}
});
The 'new content' is a div which is at the bottom of the page and is where the new content loads to! Thank you very much I am trying for a javascript code that would ask for the excel file location when run, fetch data from two columns till eof in an excel file (MS Excel 2010), append it to an existing text file and upload the plain text file to an ftp location. The ftp username, password and location needs to be hard coded in the script. Is this possible? I'l not good in Javascript and I can't find anything about what I want.. . On a sports website there is a table with our ranking and results. On this site the content is changed weekly, but it stays in the same tables.. . Is it possible to make a javascript to get those tables and put them on my own website so the content will change on my site when the content is changed on the sports site? Please help me, it would save me lot of time.. . THx Hi everyone, I am having trouble getting a loading bar to appear from my javascript. I have the following code in place Code: $(document).ready(function(){
$(window).scroll(function(){
var h = $('#footer').height();
var y = $(window).scrollTop();
if( y > (h*0) && y < (h*1.0) ){
$('#loading').fadeIn("slow");
$('#loading').delay(10000).fadeOut();
$("#portfolios").delay(1000).fadeIn("slow");
}
});
})
I have it so when the user reacher the 'footer' div of the page, new posts appear which are contained in the 'portfolios' container div. They appear fine but no loading bar appears... The loading bar 'gif' is in the 'loading div id'. There is a 'display:none;' in the css on the loading div and the portfolios div. Any reason why the 'loading' div doesn't display but the portfolios does? I want the loading gif to show whilst the 'portfolios' is loading basically when the user hits the bottom of the page. Any help would be appreciated! Thank you! Hi there, Firstly my title may be a bit misleading as I don't i'm not sure how to do it. My situation is that I have a small piece of javascript that 'cycles' through a bunch of URL's (the URL's are reports produced by SSRS). The problem is that each time the javascript loads a new URL it has to generate the report, so I have a few seconds where the screen says 'Generating Report'. What I would like is a system that never displays the Generating Report, instead I would like to maybe pre-load the next report so it is ready to show instantly. Does anyone have any idea how to do this? Any help would be greatly appreciated. Cheers, Tom. is there a way to after thye page load add an image. So maby loading it in the background and just showing it when you click a button?
I have an entirely javascript page that once it is done it still looks like it is loading. This is more of an annoyance than anything harmful. The page can be viewed at http://mikedombrowski.com/mRNA.html Thank you for your help in advance. |
