Onchange Tag Of A Listbox To Use The Values To Manipulate An Iframe - "can't Load Page" - Src Is Broken
Jun 16, 2011
I put the following line in the onchange tag of a listbox to use the values to manipulate an iframe:
document.getElementById('viewer').src=('Location_Files/')+(this.value)+('.htm') There it works perfectly but I wanted to do more so I decided to build a function around it:
function display()
{
document.getElementById('viewer').src=('Location_Files/')+(this.value)+('.htm')
}
When I put the function in the onchange tag instead, the iframe tries to work but I get a "can't load page" message like the src is broken. Now when I first made that line it took me hours to figure out that I can't use a "" because if I do it fails. So I went with "/" and that works but I wonder if that rules change when I specify it in the java script instead of in the onchange tag itself. Either way it still breaks if I try to use "".
I've written a small plugin to serve as a feature rotator and am having one strange problem.You can see some demos of the plugin and documentation here:
http://pbskids.org/pbskidswidgets/carousel.html.The plugin does a number of things that involve reading the width and height of DOM elements and using them to set the width and height of other elements. The problem is that sometimes in Firefox and Safari, when the page loads, the widths and heights of panels in the carousel are fracked.
Reload the page and the problem's fixed. In Safari, I can't get it to happen again on many reloads. In Firefox, though, if I reload repeatedly, I can get the problem to happen again: maybe once every seven or eight times.It looks like something's happening with page loading, but I'm at a loss to diagnose it further: is the script firing before the elements have fully loaded sometimes, and then works on subsequent tries because those elements are in the cache? Also: I've never seen this error in any of the IE versions.
I have a PHP page that generates a list box with several options in it.
I would like to have a "view" link next to the list box. When the user changes the contents of the list box, I would like the view link to update to point to the image representing that selection. So for example, if the list box held names of images I would want the view link to always point at the correct image.
To further complicate this matter, the selections of the listbox are in PHP variables.
I basically have little to no experience with javascript and could use some guidance in figuring this out.
I have this onchange event that occurs after user selection of a dropdown menu. When a user makes a selection it queries the database and delivers some data.
The value of the dropdown is stored in a database, but the problem is when the page is refreshed the delivered data disapears, only reappearing if you change the dropdown.
How can I make the onchange event run when the page loads so that if there is already a selection, the database data will always be there, only to change if the user changes the selection?
Here is the JS: <script type="text/javascript"> function showCustomer(str) {var xmlhttp;
I've got this listbox full of hundreds of employee names. Clicking on a name executes a function using onchange. Because of the length of the list I decided a search function would be really handy and I finally found one that works.
Now the search function, when you type in the input box, scrolls the list to the first matching entry. And that's good, that's what I wanted.
The problem comes in when you try to click on the name the search function found. Nothing happens ofcourse because the onchange tag in the list reacts to changes, not direct clicks.
code:
The list is populated by java but for testing I disabled the function that clears the "Loading" option and I set it to selected. That way the loading option is highlighted by default and the search function is free to highlight something else, then when I click on the search result it works like it's supposed to.
But keeping a highlighted option at the top of the list for that sole purpose isn't very elegant, especially since if you click on it the onchange function tries to execute and generates errors. The only solution I can think of is to use java to generate another option way at the bottom of the list that has the selected attribute but I don't quite know how to do that.
1. Load the first page of a series of pages into an iframe when you click a link 2. On each click load the next in order page 3. When last page has loaded if clicked again will start from the beginning.
What I am doing: I am creating a tutorial for a friend who cannot figure out how to use her new rental management program. I could use a manual slide show to have her click for the next image however, there are a LOT of tutorial images which show her what to do at that point. Her program contains a great number of setup screens, report screens etc. This means the slide show would be sitting there loading all these images before it will work. So, I figured, OK make a page with an iframe, and then I could put each image on it's own little page i.e. page1, page2 etc. Place a little button, or a next link, then have the link load the pages into the iframe in order.
Each anchor is unique, but the title attribute may match the exact title of one or more images. Where a match is found, either once or more, the title text is copied - once - into the anchor element.
my list box in the html page contains list box with values. these values inturn have subvalues and I have to allign the child values to right so that i can know the parent of the values. how can I do that. list values should look something like this... Code:
I have countries listbox, for instance if i choose singapore listbox it should display the corresponding states listbox of singapore, if i chose anyother country it should display a label saying "ENTER STATE" followed by a blank textbox.
I have an iframe. I load a page within it. The page I load is a php page that I build with a table with the id of 'readmail_table'. My iframe is 'readmail_frame'. Someone clicks on a message title outside of the iframe and I load the contents of the message in the iframe from the database in my table. Sometimes this takes longer than others depending on how large the message is. What I am doing here is letting the contents load then calculating the width and height of the table and then increasing the iframe's size so there are no scrollbars. This works 98% of the time but I ran into an issue where the table does not exist yet in the iframe and the JS code errors out. So what I did then was add a local var, set it to false then had a while loop check for the table and once it finds it, set the var to false and run my code. Again, mixed results. Sometimes this works then others I get that the table id I am looking for is null but my if statement in the while loop is checking to see if != null line 159 is where it is breaking The error I am getting in firebug is
[Code]...
Code: if ( window.frames[ "readmail_frame" ].document ) Like I said, most of the time this works exactly how I need it. I just need a fool proof way to determine that this table is in fact on the page. I am not sure why it works sometimes and not others since I am looping until it is there
In my jsp project i am using the calendar control which selects the Birth Date of the client and on that basis it calculates the age after completion of all the fields user get registered successfully.but when registered user trying to update his date of birth his age field is blank, tell me why this happening Also tell me the javascript function.
I have a parent page containing an iframe. The parent page has a menu in it which opens links in the iframe. I want to highlight different bits of the menu according to which page has loaded in the iframe.
So I would like to do something like this:
1. Use PHP to extract the file name (minus 'php' at the end, of the page loaded within the iframe (which I can do fine).
2. Use javascript onload so that the iframe sends this value (say 'pagename') to the parent page when it loads any page in the iframe.
3. The parent page, having received that variable into its header, will adjust a line of css to something like: .pagename {background-color:red;}
And so the menu link for pagename.php will be colored red
4. When pagename1.php is loaded into the iframe, that will send 'pagename1' to the parent page, change the CSS in the head, and therefore change the highlighted menu item from pagename to pagename1
Is this possible? And easy? There seems to be a lot of stuff online about moving variables from iframes, but mainly in the context of form entries from an iframe to a parent, eg here:
[URL]
parent.function_name(); seems to be needed along the way. But I am not sure how to proceed.
I have to to HTML listboxes one hold name of people and other hold their emails I want to ask is their away to sync the selected index between listbox a and b like if the user select a name on A listbox his email should be selected on B list box. I made it selected the name from list box a code...

solving problem with creating several different PAGEs2 poining wanted iframe src is not the case.
I'm what you could call a total newcomer to jQuery. I've got a page with a jQuery DatePicker in which I wan't to block out some specific dates that are fetched from an MS-SQL database (I'm using ASP.NET). I've gotten so far as to understand that in order to accomplish this, I should create a .aspx page that returns only the blocked dates as a string. It's done, however, I really don't understand how I am to load the string into the jQuery script.. :P
I created a bookmarklet script to help me audit extremely large style sheets.Basically while on a site that you would like to audit, you click the bookmarklet and the document's body contents gets remove and replaced with an iframe that points to the current sites home page. From here you can choose what style sheet (the script finds) to begin reporting over. The more pages you browse (through the iframe) the more accurate the report gets.My problem however, is if the person is on the site's home page when first running the script, the iframe never loads up. I think it has to do with the fact that you are on the home page, and then the iframe tries to point to the home page as well and fails for some reason.You can test it by bookmarking this bookmarklet and running it on any site's home page where style sheets can be found:
Get The Bookmarklet on this page (http://tinyurl.com/3gx7fw5)
Again, it works great if you don't start the script from a sites home page.
I am building an all AJAX site for a Facebook iFrame page and am having an issue. All the pages and what not load up dynamically just fine, but some pages use the Facebook commet system. After the AJAX has loaded the page though, the JavaScript inside does not load.
This is the Facebook comment script that I need to load inside the ajax'd content.
I have an embedded video set in an iFrame (the page is called on.php). When someone clicks the stop video button, the iframe is re-directed to off.php, and the video is replaced with a play video button -- which when clicked takes them back to the video (on.php).
What I want to do is install a cookie that will permanently 'remember' which page the user has selected (on.php or off.php)... and then from that point forward will always load the appropriate page.
I've seen all sorts of tutorials about setting cookies and stuff, but nothing that would clue me in on how to accomplish what I'm trying to do specifically.
I have a "Page A" that opens up a popupwindow called oImageDetail....
lets say the page opens the popup, and the visitor leaves the popup open...is there a way to verify that it exists in a given "Page B" or something like that?
or is it not possible because of the window wasnt opened thru that Page B?
I'm trying to figure out how I can pass multiple values to my javascript from one selectbox. code...
As you can see the product_id get passed to the javascript, but it is essential that I get the price and color id passed along... Is that possible, and if yes.how?
I have a scenario with 3 x 12 textfields and looking for a javascript that could do the trick.
What I'm looking for is a smart way of extracting the values of the first three textfields and then multiply them. This will be done for all 12 rows. I then would like to add the result from the 12 rows together to create a final value that will be presented in a seperate textfield.
row1=value1*value2*value3; row2 =value1*value2*value4; and so on....untill row12. then row1+row2+...row12
To show you what I mean I've created a small page with 3 x 2 fields at this link: [URL] The idea is then to have 12 rows and not two. Also - it should call for the function onChange.
I guess combind all the values in three seperate arrays, multiply and then add the values together could do the trick, but so far I havn't manage to do this. Maybe a for(i<12)-code could help.
In our class we were assigned a project to create a Web page with 5 text boxes, each with a value attribute of zero. When the user changes the values, it is supposed to call a caclAvg() function. How do I pass 5 values to the calcAvg() function? It specifically states in our book to create an onChange event handler for each textbox. Wouldn't it be easier to somehow create a variable onChange, then after all 5 textboxes have changed, pass the 5 variables along to the function? I know the following code is a mess, I've tried so many ways now. I'm sure this is an easy, routine procedure for most of you.
