I have a site with a news pages and I'd like the navigation to include a
blinking 'NEW!' when that page has been updated within the last three days.
It works fine for the one page (if you're on the news page, it works great)
but I can't figure out how to check the time/date stamp on a file other
than the one currently loaded ...
So I'm trying to create a custom file uploader which will display the name of the file selected, but since I can't seem to figure out how to do this I've settled for checking to see if a file has been selected, but I'm still having trouble with it.Here's what I have...
However the value doesn't change after the file has been selected. Could someone tell me a means of modifying this so that it will properly display once the file has been uploaded? Do I need to have some sort of constant refresh on the Javascript to check to see if the value has been changed?
I have seen many Javascripts on Internet that checks the extension of the file before uploading. But all these scripts checks the extension when the Submit button is pressed. I want to check the file extension as soon as the file is selected. The script should delete the selected file from the type=file box and display an error message (when a file with the wrong extension is selected).
I got a file upload form (in asp), besides of checking if the extension is .jpg .bmp etc, how do i check if the file really is an image? so pple wont be able to change an exe file to jpg and upload it right away.
In client side, we can check if some image exists using onerror. I wish the same behavior to check files used in object tag (in client cache, not in file system), like swf, wmv and wma, etc.
I was looking in the firebug debugger and noticed that my main .js file was somehow being called twice, but I don't see where. There are dozens of files involved in this particular problem, so I think the best way to go about solving it is to test - in run time - if my js file is already in place on the page, do nothing - otherwise call it. This is pseudo that I have monkeying around with but it's not working.
Code:
function checkFile() { var fileExist = new fileExist(); fileExist.onLoad = isPresent;
[code]....
I thought this would work, perhaps it's because of an argument I need to pass in to checkFile(ZYX) but not sure.
Is there a way using javascript to have it check if a file exists on the server? I'm trying to check for a file on my server without having to refresh the open webpage. If this can't be done with javascript, do you know which webpage languange can execute this?
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 am trying to update the contact in this code using an external js file and targeting the "Contact me" node using the DOM: (see my js attempt below.):
external js: (as you can see, I can't even get the alert to work, so I am having trouble traversing the DOM.) Eventually, what I'd like is the js file to setAttribute of the <a href> to my current email.
// contact me email
var getnavmain = document.getElementById("navMain").getElementsByTagName("ul");
var emailtarget = getnavmain.getElementsByTagNames('li')[0].innerHTML;
I created two drop downs, where the second one dynamically updates according to first selection. Now I jus have 2 members in first drop down and 20 in second drop down. I hard coded using javascript. But by the end of this year the number increases to 100's, then we cannot hard code it. I use html,javascript,jsp for the webpage. Is there a way to populate the dropdowns with data in a text file where they can update the text file with new members.
i want to add a part of the website that will be generated from mysql database from an external file just like php include just that i want these parts to update realtime without refreshing the browser. i also want it to have pagination.
I have a <input type = file> button for uploading a file in my php page. As soon as i select a file from the button, i need the file data to be displayed so that i check whether the file selected has the correct data. How can i do this.
I have some javascript that uses setInterval(..) to change the src of an image every second. Is there any way of programmatically checking to see whether an image is loaded properly or if a 404 File Not Found error occurs for it?
for a button called "pbRegistration" that checks to see if the value of textbox (tfOtherJobTitle) equals "test" and on completion of the typing "test", it enables the button. Why isn't it working?
...what I'm trying to do is pass through the value of the checkbox ticked through to a function. This function will then, depending on whether the box is ticked or not, untick the access# checkbox.
I can pass the number through to my function, but I'm having difficulty trying to reference the actual checkbox from the script. This is what I've got so far...
function AM_MenuSelection(opt) { var myOpt=document.frmNew.view[opt].value; alert(myOpt); }
As you can see, I can reference the value of the object, but need to be able to access the related access# object.
I'm trying to run some code when a H2 element is clicked on an unordered list below it. The problem is, the code runs whether the h2 has a ul below it or not.
h[x].onclick = function(){ var ul = this.nextSibling;
Clicking "Subtitle" runs the function on "Subtitle 2". I don't want the function to run unless the next element is an ul. How can I verify that the next element is an unordered list and if not, don't run anything?
I'm using jQuery SVG and would like to check if the browser that the person is using will support SVG --- if not, they'll receive a polite message; is there anyway to check this using javascript?
I need some JS code that will let me check and see if the date the user enters is within certain guidelines. ie...(no less than 2 days out and no more than 90 days out.)
Someone was kind enough to give me this code, but I can't get it to work correctly. Everything always returns false. If I am reading this write, if it returns false, then the conditions are not met.
Any ideas?
function compareDates(myDate, min, max) { var now = new Date().getTime(); var then = new Date(myDate).getTime(); var diff = (now - then) / 86400000; var valid = true;
var min = min * 86400000; var max = max * 86000000;
if (diff <= min || diff >= max) { alert(diff + " " + min + " " + max); return false; } return valid; } new compareDates("08/10/03", 2, 90);
I'm building a site that requires user registration, I've already built myself a PHP based user registrationg system, and it already has all the usual checks that are required before letting someone sign up (i.e. that the username is unique, that all required fields are filled, that the two passwords match, that the email address is valid, etc..) using PHP, and so I could ship the system as it is.. but.. I wanted to add some JavaScript checks to it aswell (just to be sure, and to save processor power, etc.. you know how it is). Code:
I am creating a website where I have to check the password that will be either in Upper Case or Lower Case or Numeric. Can you please tell me anyone that how I will do it by javascript.
