Is their a way of iterating thru each tag within a form and returning the value given in the id property, by that I mean the below html would return the values idBoxOne, idBoxTwo, idBoxThree from the FormXX form.
I am trying to create a form for authorised users to upload photos to an image gallery. I'm attempting to perform simple validation of the fields by ensuring the fields aren't empty and that the extensions are right. However, I can't seem to access the actual values of the fields to start with.
If I simplify my problem, can anyone tell me why this would work in a Javascript alert:
I have a form with a lot's of number of Text and Hidden Fields. I just do a simple loop to get each value for each attribute. I have about more than 2000.
if i do something simple like :
for (var i=0; i<2000; i++) aValue = i+10;
it runs well. But if i do something like for (var i=0; i<2000; i++) aValue = document.myForm.elements[i].value;
it gives me 100% CPU for a long time before i submit the form.
Is there a way to retrieve the DOM element number in a form? For instance if I had 5 checkboxes with the same name and an event was fired to gather data, could I determine the DOM element number for each checkbox checked? I know this may seem like meaningless information, but I need it to do some other work on the page.
So I'm a novice coder and have been trying to piece together a (seemingly) simple function. I want the user to be able to enter in a certain amount of time into a form, and then when they click submit, it opens a new page and closes after that amount of time.There is a very simple form on the first page that accepts input and looks like so:
<form action="onbreak.php" target="_blank" method="POST"><p class="fillable">I would like to view <input type="text" name="url" id="url" value="" size="30"/> for <input type="text" name="timeinput" id="timeinput" value="" size="3"/> minute(s). <input type="submit" value="Break Me!"/></p></form>
HTML Code: function makeForm(name) { mypara=document.getElementById("paraID"); myform=document.createElement("form"); myselect = document.createElement("input");
[Code].....
I am creating a form dynamically using javascript.The form is created successfully. After creating the form before submitting the form i would like to make some check points before submission.so while creating the form i am adding the event on submit=call function for validation .THe function is called successfully but i am unable to retreive the form values in the validation script
So, I have a form that, when the user clicks on a link, uses J/S to generate extra form fields for extra information. I can retrieve the value of the dynamically generated fields using $_POST in I.E., but it doesn't work in Firefox (no value is returned). Retrieving values for the static fields is fine in both I.E. and Firefox.
Here's the code - is there a function I'm using that could be replaced with something more friendly to Firefox?:
<script type='text/javascript'> var i = 1; function addArea() { var newArea = addElement();
I have the code below that will retrieve a cookie that was placed by the server (ie: joes.com) that the document resides on. I want to be able to retrieve a cookie set by another server (ie: freds.com) but I want to retrieve it from a page served by joes.com. This code apparently using 'document.cookie' determines the server that the document resides on and looks for cookies from that server. Anybody know of code that will let you determine the server?
var name = "cookie"; function getCookie(name) { var cname = name + "="; var dc = document.cookie;
if (dc.length > 0) { begin = dc.indexOf(cname); if (begin != -1) { begin += cname.length; end = dc.indexOf(";", begin); if (end == -1) end = dc.length; return unescape(dc.substring(begin, end)); } } return null; }
i need some help with an assignment. the program needs to display a list of flights from options selected from drop down menus. i have written the code to display all flights, now i need to write the code to include the options such as destination and airline. here is the whole of the code.
function Xml_feed(file) { this.load = function() { var txt, str, title; var threads = xml.getElementsByTagName('thread'); var len = threads.length; var box = document.getElementById('box-a'); while (len-->0) { txt = document.createElement('button'); title = threads[len].getElementsByTagName('title'); str = threads[len].getElementsByTagName('author'); txt.setAttribute('label', title[0].childNodes[0].nodeValue + ' by ' + str[0].childNodes[0].nodeValue); box.appendChild(txt); } };
var xml = document.implementation.createDocument("","",null); xml.onload = this.load; try { xml.load(file); } catch (e) { alert('There was a problem loading the XML file'); } } var feed = new Xml_feed('blah.xml');
in the red:
Is that how I should be retrieving the value from a child node? (the getElementsByTagName)..
in the blue:
I tried doing this.xml but had problems with doing that, i.e, this.xml = document.implementation.createDocument("","",null); this.xml.onload = this.xml.load; try { this.xml.load(file); } catch (e) { alert('There was a problem loading the XML file'); } I'll guess that text in the red is why.. btw, this was in an XUL app.. not sure how much that would matter though..
We are facing a problem with alt attribute in Java script. While retrieving alt attribute in IE its working fine but in FireFox we are getting as undefined. How to retrieve the alt attribute in firefox.
Please find the below code for how I am retrieving... <html> <head> <script type="text/javascript"> window.onload = function(){ var els= document.forms[0].elements; var compcode =""; for(var i= 0; i < els.length; i++){ if (els[i].id!="") { alert(els[i].id); alert(els[i].title); alert(els[i].alt); }}}
</script> </head> <form action="#"> <select name="test" id="testing" alt="test|001" title="test|ddd"> </select> </form> </html> The above code is working fine in IE but not in firefox.
For a personal project, I want to see if I can make a Greasemonkey userscript (or eventually a Firefox add-on) to list how far a certain ad on Craigslist is from where the user is (by the city listed beside the ad). My question is really just looking for ideas on how I can parse out the city's from the webpage text (with javascript or some other language?). Not even sure if this is possible.
The city's or ads aren't their own div elements or anything (nothing can ever be so simple) - but the city's listed are formatted by <font size="-1"></font>, and each ad is in it's own paragraph tag.. maybe I can use that somehow?
I'm trying to figure out what I'm doing wrong here. I have a select control and I'm trying to determine what index or value was selected and I can't seem to get it to work right. I'm sure it's something simple but I'm new at this.

I am looking for a solutions for the following problem, I need to access at database from within a website, from where I can retrive a specific document in the database and mailing it to someone else.

Is it possible to pass information back from a popup window?
I am looking to open a popup from our internet site to our web based mainframe app (HATS). I would like to send some strings from this popup page back to text fields in the calling page to populate a form. Does this sound possible?
Basically I am working on the development of a database where a user enters an address (street, city, state, zipcode). Based on the user input of the address, I need to dynamically determine the latitude and longitude of that address from the internet. Code:
I'm not sure why I'm having problems with this but if I try to retrieve the value of a readonly text form I get back that the object is undefined.
The reason the text is readonly is because it's a date which I set via a calendar javascript program (associated with a button) only so the user can't put something silly in requiring validation.
The form send the data correctly when submitted it just doesn't seem to be able to be read.
I am currently using jquery to regularly speak to my serverside to "import" a html fragment (which has varying components depending on user selection).What I want to know is:Is there any way I can access the html within that div through jquery?TOP LEVEL PAGE
I am using a generic Template in a site where different domain names may enter at different levels of a web site.By using some CSS in my <header> to set the base url.I am able to refer to the address of an image by just having.By changing the BASE URL I am able to change which image will display.So I need to obtain the URL address that the viewer, came into the web site on, and then set the BASE URL.
I an designing a website and the user need to select from option of three values. Each option selected have a numerical value. On selection the numerical value attached to the selection will be multiplied by the another value in an input box to get a final value.
I am looking to insert a keyword in to a javascript alert box when someone visits my website, so say they came from codingforums, it would say "Welcome, CodingForums.com Visitor". My keyword will be passed from the ad platform I am working with and shows up correctly in the tracking, so I'd imagine it's just a case of having the snippet of code for it to show in the alert, correct? If there is no keyword, I would just like it to say "Welcome Visitor" or something.
