I want to know if there is a possibilty to check with JQuery if an image can be loaded or not? Because when an imgae can't be loaded the Jqzoom should not work, because the big image (which is for the zoom) could not be loaded. Imagin I have hundreds of pictures, how can I check if this big image could be loaded or not?
is there a way to assign an event to a file input so that when a user selects a file to upload the event is triggered and i can check out the file extension? The reason why is simple, i want to perform different actions depending on the type of the file.
I have my site all set up with a horizontal accordion menu and a content area into which I load a DIV via jQuery from an external php-file.
Let's say I have the content of one category loaded and I offer two links to switch between subcategories. Now of course I could simply have the content in different DIVs - both loaded and only one at a time visible and toggle. But the markup is always the same, only the text in different. So I would prefer not to repeat the markup and instead define the text through a php-variable and an if-else-construction. To achieve a result, I would need to reload (or rather reparse) the already loaded php-file with the new condition when clicking on the subcategory.
Is there a way to "unload" the ajax-loaded file or reload it? I tried simply loading it again and also removing the DIV before that. But it didn't work. Also now not solely the DIV is loaded but the whole page reloaded. Neither

I have been mostly working with php and prefer it in these cases also in terms of progressive enhancement.
We have to login to a http page so that I can surf the net. But, that login page also requires me to keep that page open which is very irritating. The page have javascript that checks if the page is loaded every 180 seconds, it its not loaded, I am logged out.
I want to simulate a browser using a programming language like python or using curl or anything so that I am not forced to keep the webpage open. How can I do that? I have uploaded the source code of the webpages of login_page, javascript and ajax scripts used.
I am not actually sure as to how it is being accomplished so I dont know how to simulate it. note the sendLiveRequest function in javascipt script.
I'm loading a (HTML) list from mySql via PHP into a main page using load. The main page is linked to a css file and a js file (jquery). The loaded data assigns the css file BUT does not seem to be able to find the js file as the click handlers in that file do not work. I'm new at this and this is probably a BASIC issue.
I was wondering if anyone has figured out a near-perfect way to check if the client has all the elements fully loaded? Not talking about all the css and text loading and the event triggers while the client is viewing images load: I mean the event auto-triggers after all the images are fully loaded, along with the css, text content, etc.
(P.S. Not talking about AJAX. Literally when somebody visits a page itself, the elements all completely load first, then the event fires.)
I am attempting to do two things and I'm missing a vital element: ajax call to an XML file to be inserted onto a page, FOLLOWED by selecting these newly created elements to apply event handlers on them. I am near certain that the problem is that the selectors are not 'seeing' these elments and it's an issue of running the event handler only AFTER these elements have been loaded.
How do you do this? I already have a $(document).ready(function() { in order which I naively thought would take care of this exact issue...
I need to be able to use jQuery's load function to grab the contents of an external file and append them to a particular DOM element. The problem is that when that external file includes scripts that contain calls to document.write, I get weird behavior that changes depending on which browser I'm using.If I'm using Internet Explorer, the load function gets all of the non-script elements from the external page and correctly appends them into the DOM element. Of course, this is not ideal because it ignores the scripts.If I'm using Firefox or Safari, the load function runs the scripts but the document.write output overrides the entirety of the calling page.Thus, I end up with a page that now only contains the document.write output instead of a page that includes the original HTML plus the document.write output as a child of a DOM element.
I have a form with three Input File form objects in which the user can add image files. But I am worried about the problems these controls can lead, because to check the file size the server needs to receive the entire file, so serious problems may happen, for example:
1. Malicious user trying to collapse the website sending big files.
2. Users that have not seen the warning “Maximum size: 100 KB� for each image, and try to send three image files consisting in 1,5 MB each one. These users will have a bad experience waiting one hour or more to upload the images, and after that receive an alert saying “Oooops! Your image files are too big.� And also, web server will waste an important amount of resources. The same case with 100 users at the same time can be a nightmare!
I have been searching a way to check the file size on client side without having to force user to install anything, but I think that there isn’ t nothing to do with javascript. But I found an interesting PHP article that explains a way to do it with this server side language. The technique consists in:
“A hidden field (measured in bytes) that precede the file input field, and its value is the maximum filesize accepted. This is an advisory to the browser, PHP also checks it. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too big and the transfer failed. Code:
NOW : I need to click on a button or a link to load the external second.js instead of the old one first.js I don't want to use any iframes... Any idea how to load external js files in <td> tags or any other place in html page.?:rolleyes:
I have an XML file that I'm trying to load into and xml object, however the doctype tag is killing the javascript, and does not parse the XML at all. If I remove the doctype, the javascript can parse, and I can access the XML DOM. So I know the XML is valid. Even with the Doctype, it validates. However Javascript does not like it. I don't have a choice to remove the Doctype tag of the XML.
If I remove the Doctype, this method works to parse the XML DOM: Code: xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); xmlDoc.async = false; xmlDoc.load(filename);
Also, if I use the .open method to retrieve the XML, I cannot access the XML DOM via xmlhttp.responseXML. But I do get a result when I use xmlhttp.responseText, it displays the corresponding XML. Code: xmlhttp.open("GET", filename, false);
This is probably going to show how new I am to jQueryI have a form with an input text field for entering a URL. The user will most likely paste a URL and I want to automatically verify it's status once the user leaves the field. Basically just make sure the page loads ok.I've found dozens of topics that are close to this, but my lack of jQuery skills is hindering me from adapting any of them properly.
I have a php page its only work is to display a swf file and after a period of time it redirect automatically to another page. The problem is when the php page loads the swf plays slowly.
What I nead the php file is to wait untill the swf file is fully loaded then play it so it will be played normally in normal speed?
I am using jquery.validate.js for my validation. I need to validate some dynamic input fields. By using class now I am able to validate that. Here my problem is to validate for the file extension.
For static files I use as file: { required:true, accept: "png|jpg", },
How to write the accept validation for dynamically generated input fields. Below is my input field where the ID and name will change for every input field.

Code: if(window!=top)top.location=location.href; function RateItem(varItemId, varRating) { var varOrigClassName = document.getElementById(varItemId).className;
I am having troubles finding a way to use JavaScript to see if a file exists before an ASP file upload script runs. Is there an Exists check for JavaScript? I thought I found an ObjectName.Exists but doing this did not work.
I would need javascript code to check extension of uploaded file. File upload in not mandatory, but I need script to check extension and allow only JPG, BMP, PGN and other Image files.
I am trying to find a way to search to see if there is a specific file located in the current directory on the server. If a folder contains file1.txt or file2.txt and depending on which file is in that folder change a certain javascript variable. What it comes down to is, is there a way to search for specific files on the server and limit that to the current directory/folder.
