I went to the PHP section of this site and posted this same question, but someone told me it's a javascript question. I'm trying to carry a string from one webpage to another. The user inputs some data on page 1, the info gets tested for certain elements, then gets sent to page 2. The problem is the strings aren't transferring and I don't know how to use sessions to transfer them. I need recipeNameEl, ingredientsEl, and descriptionsEl to be stored to a string and then transferred to the page the form's action="" attribute points to.
<script>
function checkFields() {
var recipeNameEl = document.getElementById( 'recipeName' );
let me say up front that my experience with JavaScript and "Ajax" interactions has been horrific. There are weeks I will never get back because of it. Whenever I encounter something so horrific that it makes me blank my memories of the event, I find myself going back and trying to take different approaches to understanding what happens.
This current round of experiments involves sending and receiving what is effectively an associative array. That is, I want to send dom names and the associated values via XMLHttpRequest calls and on return, get a set of dom value pairs and push them back into the current environment in the browser.
what I need to figure out how to do is associate a series of DOM's with a button, extract the information when the button is pressed, and then present the entire array to a CGI. On return, I would need to take the same array from the CGI and transfer the contents into the specified DOM's
if this is not practical, tell me so and I go do something else which is probably more fun. If it is practical and has been implemented in some toolkit, fantastic. It saves me some pain. If it hasn't been implemented, well, there goes the more hours that I will never get back.
i got this javascript-function that changes the entries of a selectbo depending from the selection of another selectbox:
function changeBezug(selectedEntry, '$exhibits', .....) {}
the string '$exhibits' holds all the entries for the option Entry i the first selectbox; Unfortunately i get javascript error unterminated string literal an the error pointer points at the first apostroph: function changeBezug(selectedEntry, '
I tried replacing all special chars in $exhibits, even putting th string directly into the function code with php and tried using quote instead..
Now im out of ideas! Maybe im using the wrong replacement for the apostroph... i use ' is that wrong? i also tried ' to no good either.. what's the right one?
I have 2 fields for phone number.one is of size 3 and another is 7.After reaching maximum size for first field it automatically focus next field.I coded it as
I have a multiple select box and want to be able to select from this box and transfer the selection accross to a div using an "Add" button. I have this working fine but I want to append to the list, rather than replace the list when further selections are made.
I somehow need the function to remember the original selected array and then merge the new selected array and the old array if another sleection is made. This is all I have so far...
function editOptions(action) { var optionsBox = document.getElementById('optionsBox'); var selectedArray = new Array();
It launches in IE and give the user instructions, then at the click of a button, launches my setup.exe. I want my webpage to launch setup.exe then go to another webpage on my CD, congratulations.html, which says "installation is complete etc". Here's what I am trying to do through JAvascript. It doesn't work. Should the first instruction be flushed in order for the 2nd one to work?
I want to use the values of text boxes on my HTML webpage to create a webpage URL (like below):
<script type="text/javascript">
My text boxes are as follows:
Now this all works and the result webpage URL prints to id='ID1', but the big question is how do I use this resulting URL in another Javascript section as the src="?
I am trying to display a webpage from another domain and tried to access its elements and I am facing issues with this.
I tried using "iframes" and am facing cross domain issues.
All that I want to do is, set and get the attributes of the elements of the webpage from the other domain (eg: set text field value, get dropdown box values, click button etc)
Is there a way to get this job done?
I thought of browser addons however it will be a browser specific solution.
Could anyone know the script code for a WEBPAGE ON TOP OF A WEBPAGE? The site was not working anymore, so I can't tell you the link. This is what I saw, When I visited the site (Mainpage) There's just a Welcome Image that shows CLICK HERE TO ENTER. After clicking the link, a loading faded icon appears on top of Welcome Image covering that Welcome Image with Webpages, it's like popping to the center of the page. I don't know if someone of you could understand me. It's like Page on TOP of another Webpage without leaving the 1st page.
I have some JavaScript which is splitting out the different variable elements from the URL.Now, how do I set the internal variables?Then I want to set the variable ScriptHeading to be Change and the variable ScriptType to be NewThread.I keep finding all sorts of lovely code showing how to split out the various sections in many different ways, but I can't find anything on how to actually set these variables.
I have a program written in Javascript and fully functioning which takes a user-selected directory name and then displays all the photos in that directory in a certain format.
I am now wanting to expand the program to allow users to optionally enter their own strings and the program will use all the photos from www.flickr.com which use that string as a tag.
I have a PHP interface to flickr (called PHPflickr) which collects all the relevant photo urls. I now need to get these images back into my Javascript so I can process them using the existing functions (rather than rewrite all my functions in PHP code and have two sets of functions in the program). I found on another thread a means to do this for a date variable:
but being completely new to PHP I'm not sure what "addslashes" might be or what formatting will be necessary if I am starting with an array of urls. Code:
I am an effectivebrand.com toolbar user and would love to add apreloader to my toolbar, but am having problems doing this.Is it possible to have javascript look at the URL of a webpage, thenfollow links on that page, looking for images within that website (sayone page deep). Once found, could the images be preloaded into thebrowser cache?
I'm trying to open up an internal link from my leftnav div into my content div. I used the following JS code from my book but im not quite sure how to make it all work.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head>
I don't know a single bit of javascript so ><. I need code that in the middle of a page just loads another page, without any delay time. There is html text before this so I can't use the php header tag and I know that none of that html will be visable but this is going to be in an if statement so it's not like it's compeltly worthless.
I am using javascript to run couple of video on my web page with wmp embedded on the web page. The script and the code works ok when when I am running on my computer but as soon I download files and web page to a remote server the video files dont play. I am puting the code below:
<script type="text/javascript"> function play(media){ document.getElementById('mediaplayer').innerHTML= '<object classid="clsid:22d6f312-b0f6-11d0-94ab-0080c74c7e95"'
how to have a lightbox-like pop up in my webpage (not a seperate window) and they have 2 options. Option 1 just closes the box and goes to the page, and option 2 opens a new tab or window, and at the same time just closes the box so visitors can continue browsing the original site.
I have a footer that is appended to all of my web pages as an include. The pages are different lengths of course so that location of the div in pixels from the top of the page changes with each page. I need to access the location of a div within this footer for reasons I won't go into. The footer may of may not be nested inside other absolute divs, depending on the page.
This:
var obj = document.getElementById('BottomMenuDiv'); var xlocation = parseInt(obj.offsetLeft); var ylocation = parseInt(obj.offsetTop);
will give me the location of the div inside it's parent div. I would like to do something like this:
to go all the way to the top of the page. (Or is there some way to get the divs absolute position without going through it's parents?) What would be the syntax to do this?
Unfortunately, sometimes the target webpage is not available and I get "page not found". That immediately kills my application, until I manually restart it.
Is there a way in javascript to first check if a link exists before the form is submitted?
For php programmers, an example of what I want will be:
if(fopen("http://www.example.com/", "r") { do something here... }
How would I access the source of a webpage? I would like to get the source, then use a regexp to find text on a webpage. For example, retrieving a counter, or some other text that dynamically changes. I'm implementing this for firefox.
right now, i have a web page opening that contains that info, but i would rather have a pop up alert() that shows that info.
In practice you can't. While you could create a suitable encryption system with a password in the page, the level of support you need to do this means it's always simpler to do it server-side. Anything that "protects" a page other than the current one is definitely flawed.
