Post An Invisible Value To Js File Getelementbyid?
May 9, 2010
I keep getting an object expected error at the start of my <body>I've set a form to value="Accountants" and <body onload="showindex()"> in an attempt to automatically submit this value to a js file whenever the page loads. My aim is to have dozens of html pages all using the same js file to return information based on the contents of that value.
I'm making a form for my rural neighbors' electricity calculations. My main problem is getting the Previous and Current reading to subtract each other and post in the "kwh Used" column. My plan is to continue doing the calculations after I find that value. Here is the code thus far:
I have a issue with a javascript code that I wrote. This script is a simply for calculating the summation of 2 text input boxes and printing it in another text input box within the form. The entire form is then sent using Form post.The total is written back to the form's total text input box using the code below:
document.getElementById ('total').value = total
This code works perfectly for displaying the values on screen. However, when I send the form (PHP Post), the " total " field is empty. I have searched all over for possible solutions. But no solution yet.
1. document.getElementById ('total').INNERHTML = total .This does not even work on screen and total field is not updated on screen. Needless to say, the PHP Post variable was also empty.
I'm trying to read a file (will be a firmware update) into a byte array or binary stream or stream of some sort, and then POST it to my server. Any suggestions on opening and reading files from within js? Note, the server is a development server and will not run PHP or CGI scripts for example. I just need to be able to open a file from within a js function.
Also, no ActiveX objects, this needs to be Cross Platform.
I have two variables that I would like to use jQuery serialize and send to a PHP file with a post. I don’t know how to format the command to serialize them. Here is the start of the code. How do you serialize the day and month variables?
var currentTime = new Date() var day = currentTime.getDate() var month = currentTime.getMonth() + 1
I've used a few jquery things before, but I haven't a clue when it comes to javascript, so I've mainly just modified variables here and there. This is my first attempt at actually writing something, and well.....its not working
Im trying to send an ajax post to an external file, which simply returns 'Complete' after updating the db. My html gives me an ul, with li elemnts, representing names of comics.
I have a php-loop to read an xml file (id and comment). Now to my question, must i write the Script into the loop or can i assign via a parameter (or whatever) in the header Script?
I want to restrict getElementById to search children of a specific element instead of searching the entire document, in the same way that I can do getElementsByTagName using a specific element as the parent.
In this particular instance the parent is a table and the elements I'm interested in are all TDs, so I did the basic getElementsByTagName('TD') off the table and looped through this array checking the IDs. However, I'm suspecting that the browser can do getElementById faster than I can do a loop in javascript. Is there a neater way to do this? For now, I'll settle for IE-only solutions, though it would be nice to have things work in generic browsers.
i would like to have a popup window from a parent window. this window should refresh every 5 seconds and reload parent window. OK i know its dumb, but i have my own reasons to test this. NEXT: is it possible to make this popup window invisible ?
I had no experience with cookies up to today. I read about the properties of cookies. Then I started to write a few lines of Javascript into my html-page:
function SetMyValue(name, val) { document.cookie = name+"="+val; }
and
SetMyValue('firstname','michael');
I did not set the properties "expires" and "domain".
When I put the page to my server, called it with the IE 6 and looked into the IE for my cookie, it was not there. But when I made a cgi program that showed HTTP_COOKIE, I saw, that the IE was sending it. So I had an invisible cookie with my IE. Only when closed the IE and opened it again, it was lost.-
I would like to make an hyperlink invisible, or disabled, with a click. The hyperlink opens a new window (target = _blank) and once the new window is shown, I don't want the hyperlink to be active anymore.
Simply question: I want to have a DIV start by being invisible, then fade in but I am not sure how to start in such a way that jQuery can make it fade in.
The code below sometimes works the way I want it to...by downloading a video from an external site and displaying a placeholder whenever the page loads. But most of the time, the video won't download and display until a user hovers their mouse over the blank area.
Is it possible to modify the code so that it functions consistently by always downloading and displaying the placeholder when the page loads? I don't want users to think there's a missing/broken video because there's a blank space where the video is supposed to be, and they don't realize they have to mouse over it.
<a href="#" onclick="return(false);" rel="videoGUID=4cd75af679b39g4963V828c00c581024ae86&" style="display: block; width: 550px; height: 310px" id="4cd75af679b39g4963V828c00c581024ae86" width="550" height="310">How to Take Care of Your Dog's Teeth: VetVid Episode 001</a><script type="text/javascript" src="http://360.sorensonmedia.com/4cd75af679b39g4963V828c00c581024ae86/embedv2.js"></script>
I understand how to make a div (table) invisible and then visible on a timer.. What I want to do is add a counter to my code and make the table flash 3 times and then stop with the table visible. all my code does right now is make the table flash on and off every 1 second. This is what I have right now:
<script language="javascript" type="text/javascript"> function magic() { var d = document.getElementById('MagicTable'); if (d.style.display == "none") d.style.display = "block";
i have a div with a dropdown box with autopostback="true" if i change the selction frm dropdown the div becomes invisible which i dont want how do i rectify it at present i have a html button control with a function to show the div
on load function i have the div style=none when i click on the button the div is visible but when i change any selection frm drpdown the div becomes invisible
I have a div that is invisible all the time, and when one popup is activated, that div will fade in to darken the website background, like this: And I'm using the following code when the darkness appears:
PHP Code: function raiseOpacity(obj,counter) { obj.style.opacity = counter/100; counter +=2; //Raise 2% each time if(counter < 100) setTimeout(function() {raiseOpacity(obj,counter)},10); //Repeat the incrementation again}raiseOpacity (document.getelementbyid('example'),0); //Just an example of how the function is called.
But it is too slow, the browser hangs alot while doing this. Is there a faster way to do this fade in stuff? I've seen a lot of websites that do this and the browsers is fast, but I couldn't extract the code from them.
I cannot succeed in getting any key event on a div that's been set invisible by the style's MozOpacity property under firefox. I'm using this method so that I can capture the mouse events. Unfortunately, it appears to do so only with mouse events, not key events.
refer to my development site - [URL]... If viewed in IE6, it has no header graphic and no border graphics. Before the implimentation of PNGFIX it looked like attachment image 1. After implimentation it looks like attachment image 2 The files in use are jquery-1.3.2.min.js and jquery.pngFix.js. I have also tried using jquery-1.4.4.min.js but this does not change the situation. jquery-1.3.2.min.js has been reverted to as it is native to the Coppermine Gallery.
I have a radio button set that I am trying to use the onclick method to mae one row visible or the other. Let me show you what I mean. I have this javascript defined. I tried to use pointers but then I got element has no properties. So I've reverted to useing the full DOM call. Code:
