How To Access Name Value Pairs From A <select>?

Apr 5, 2006

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.

Transferring Dom/value Pairs

Jul 26, 2006

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.

Fail To Make Key / Value Pairs?

Mar 28, 2010

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.

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.

Parsing Through CSV To Get Specific Name/value Pairs?

Oct 2, 2010

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].....

JQuery :: Modify How Name / Value Pairs Converted In URL

Oct 1, 2009

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);
}});

May 4, 2009

I have the following HTML within a form

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?

JQuery :: Select All / Select None *text* Links In A Form That Call A Jquery Function To Select All Or Select No Checkboxes?

Jun 16, 2011

I've seen a variety of implementations around that enable selecting all or no checkboxes by using a checkbox to toggle that choice. However, I'm trying to find a way like this: I have two text links on my page: Select All, and Select None. How can I get those links to call a jquery function to select all or select no checkboxes in my form? As a little food for thought:

<head>
$(function() {
//function for selecting all or none...is there a way to make a single function that passes in a parameter to differentiate between selecting all or selecting none, or do I need a separate function for both?[code]....

Pass Text From One Select Box To Another Select Box Using The For Loop To Check The Existence Of An Item But It Is Not Working?

Aug 28, 2010

i am trying to pass text from one select box to another select box. The logic is if 10 are added, no more passing must happen. Also if an item is already added, it mustn't be added again.I am using the for loop to check the existence of an item but it is not working: what am i doing wrong?

Code:
function PassSelectValues(){
//pass values from select boxes to select boxes
var counter;[code]....

why isn't counter incrementing at all? The alert message box does appear saying item exists but the item gets added anyway.

Disable Select Until User Puts Mark In Check Box. Then Enable Select?

Jun 26, 2010

disable select until user puts mark in check box. Then enable select.I have two select box's on a page. The first asks what product, the second is based on the first and presents a list of pdf's according to which product the user selected. (yes, multi dimensional)What I have works fine, but now i need to make the user put a check mark in a check box before the First SELECT box becomes enabled/available.So basically, when they agree, they can get the download.Here are my select boxes.

HTML Code:
<form>
<select name="category" style="width:180px"></select>
<select name="site" style="width:180px" onchange="openLink(this.value)"></select>[code]....

(ignore the The 'open' button. It's there in case the default option is what the user wants, so they don't have reselect via the select box.)

1. How do I disable the select boxes by default on page load?

2. How do I detect that the user has put a tick in and the enable the disabled Select box?

Expected '' Error - Select Menu 'Customer' Which Triggers A 3 JS Functions - To Populate 2 Extra Select Menus

Aug 18, 2010

I'm having problems with a Javascript 'Lookup' function.

Basically, I have a select menu 'Customer' which triggers a 3 JS functions, to populate 2 extra select menus.

Using IE Developer Tools, during debugging, I get this error: Expected ';' Error

This relates to either: eval(ajax_CustContact[index].response); OR eval(ajax_CostCentreContact[index].response); (it's a bit random, as sometimes it works, sometimes it doesn't)

I have tried changing the 'custid' to 'custname' to check whether it was an integer causing the problem, but had the same problem.

JQuery :: Auto-select A Select Box On Postback With User's Selection

Feb 12, 2010

I have a ColdFusion page with a select drop down list. On submit, I'm storing the value in a cfparam and trying to use jQuery to auto select that particular option. Currently I'm using :contains but this is unacceptable because it selects the last item that contains the cfparam.

$("option:contains('<cfoutput>#form.company_type#</cfoutput>')").attr('selected', 'selected');
Is there something like this:
$("option").equals('<cfoutput>#form.company_type#</cfoutput>')").attr('selected', 'selected');

[Code]....

I willconsider other alternatives to accomplishing my objective.

Get A Select Box To Display Text From A Database In A Div Tag From The Select Box Populated By A While Loop

Jan 21, 2011

I'm trying to get a select box to display text from a database in a div tag from the select box populated by a while loop that also pulls from the database. The only way I can do this is from a javascript written by sending it over to a second page and I need it on just one page. Here is my code below:

<?php
session_start();
$q=$_GET["q"];
$num = $_GET['num'];
$test = $_GET['oneGram1'];
$_SESSION['oneGram']=$test;
[Code]...

Even if this is a wrong way to go about doing this can someone post just a simple script using a select box and displaying data on the same page?

JQuery :: Select Dynamically An Option In A Dropdown Select?

Aug 11, 2010

According to [URL] intended way for jQuery to change dynamically the selected option of a dropdown select control isassigningthe desired text instead of the value. I found this way veryinconvenient (data structures usually deal with value codes, not value descriptions) and it seems to work only sometimes.

Trying different options I came out with this approach that seems to do the job so
far:

function setSelect(pID,pSelectedValue)
{
$('#'+pID + ' option:selected').removeAttr('selected');
