Get Form Input Name And Value Pairs?
Sep 11, 2010
I'm trying to figure out how I can create javascript code in a bookmark that pulls the names and values from the form inputs in a loaded document.In addition it would also be nice if the code knew which form has focus and just pulled the input names and values from that form.I've been trying to figure it out, but the only portion I could get to work so far is:
Code:
javascript:(document.write(document.forms[0].elements[0].name))
I don't really know where to go from here. Writing javascript in a javascript:() seems to be different and beyond my level.

I have the following HTML within a form
<!-- height -->
<label for="height">
Height (cm)
</label>
[Code].....
I suppose I should somehow loop through all the labels, and for each find the next input. Then make a selection of this union and apply a wrapAll('<div class='field'>) But how exactly do I do this using jQuery manipulators?

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.

Say I have:
<select>
<option value='a' > First
<option value='b' > Second
<option value='c' > Third
</select>
Is there a way I can access the values First, Second and Third from an array ? I want to write a javascript function that can automatically select one option based on a regular expression match of First Second or Third.

I have the following form:
<form id="registrationForm">
<input id="forename" type="text"></input>
<input id="surname" type="text"></input>[code].....
...which suggests my JavaScript is partially working, but is failing on my attempt to make Key/Value pairs. Unfortunately, I'm not knowledgeable enough on JavaScript/DOM to identify an error and would be grateful if a more seasoned programmer could let me know the error of my ways.

I have a task that could be made much easier if I built a simple tool to parse through a CSV data pasted in a text area and it spits out specific the parts the name/value pairs I need. I do not have the luxury of a database and the data is a bit sensitive or else I would not be needing your fantastic assistance and I would have churned out some server-side magic.Anyway, what is tripping me up is the necessity for regular expressions (and my lack of experience in this area in general), which can drive a man to drink. I can work with the code to get the specific parts I need and manipulate what is spit out to my specifications but its the starting point that I need help with.
I pasted a sample section of the data I need to parse through.I am pretty sure I can work with the data once it gets split into an array that can be searched through.
Code:
col1
col2,col3,col4,col5,col6
"head1",[code].....

Whenever execute the following code, the URL that is formed has "?" before my name and an "=" before my value (so the URL would be "[URL]"). I need the URL formatted so that a "+" is in front of the name and a ":" (colon) to be before the value (i.e. formatted like "[URL]"). Is there a way to change this behavior?
$.ajax({
url: lansaUrl('proc', 'func'),
global: true,
cache: false,
type: "GET",
data: ({"acct": object.value}),
dataType: "json",
success: function(result){
$("p#customerInfo").innerHTML += " "+result;
},
error: function(xhr, desc, exceptionobj) {
alert(xhr.responseText);
}});

The URL is similar to:
https://url.com/form.htm?string=p,val1*l,val2*m,val3*t,val4*d,val5
Within the form, I have the following statement:
<input type="hidden" name="string">With this statement, string should take the value "p,val1*l,val2*m,val3*t,val4*d,val5"
I'm having a problem with the following script:

I'm not sure if I'm calling it the right thing, but I'm trying to dynamically create a bunch of key => value pairs in a javascript object.
Something like this:
Code JavaScript:
But the console gives me errors, and I haven't been able to find a way to do this. I've tryed putting the keys in square brackets, as was suggested somewhere online, but that didn't work.

I need to have this setup as a client side cookie (javascript disabled - no problem).
I need to store in the cookie page name, first name and last name (and there are about 4 more items). Should i save a different cookie for each item here (all javascript examples show this) or can i do some thing like this?

I've have a function to take the value entered in a form text box, add 50 to it and put the result in another text box.
When I enter 650.5 I get 700.5 exactly how I'd expect. But when I enter -650.5 instead of getting -600.5 I get -650.050 as though it is failing to parse the float due to it being negative. My understanding of parseFloat was that it recognises negative numbers. Is there a nice simple way to get this to work?

I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.

I have a form that has a reset button, and when it's closed, the form is reset. However, at least in testing on my own machine, I notice that the form fields are remembering past input (on Firefox 4 anyway). Once this goes public, I don't want the form remembering anything in case the website is viewed on a public machine. How can I keep the form fields from remembering any past input?

There are two input fields in a form, but only one of them is required, they are not required at the same time. Either A or B is required. ( A is required OR B is required). In other words, a user can input data to field A, or he can input data to filed B, but he can not input data to Both A and B at the same time. How to implement this constraint in Jquery form validation?

I have a variable that corresponds to an INPUT element...Given that element, how would I get the FORM that it belongs to (for instance, to attach an onsubmit):
var apartment = document.getElementById('apartmentNumber');
var addrForm; // somehow assign this the form containing apartment
addrForm.onsubmit = function() { return 0; }
Of course, the actual logic I'm attaching to the form is a bit more complex, but also irrelevant at the moment.

Lets say I have an empty array and I want the user to be able to enter as many new numbers as the user wants into the array. Could you explain how? Simply put it: How can javascript parse a textarea and input it into an array. (Like if the user entered 1 3 5 7 4).
<script>
function example(form){
var myNumbers=new Array();
then I'll do something with the array once the #'s are loaded...
