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.

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.

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

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.

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);
}});

JQuery :: Surrounding Pairs Of Label+input With A Div?

May 4, 2009

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?

Greasemonkey Seems To Fail With Too Many Gm_xmhttprequests?

Mar 22, 2006

I'm trying to write a script (my first) that loops through some table
rows and gets some data from another page using gm_xmlhttprequests. It
works if I keep the loop to one, but if I try and loop through all the
rows, and therefore have say 10-20 gm_xmlhttprequests, the script just
seems to fail. But if I put an alert inside each gm_xmlhttprequest, and
wait a bit before dismissing the alert, the gm_xmlhttprequest will
succeed and the data gets updated as planned. It seems as if the
gm_xmlhttprequests don't block, or the script keeps executing without
waiting for the requests to finish. I don't have any listeners on the
script, I just want it all to load when the page loads. Also, I looked
at the javascript console and it doesn't have any errors about the
gm_xmlhttprequests.

JQuery :: $ In Id Causes Selector To Fail

Jun 16, 2010

I'm trying to add some functionality to a existing application. I have no control over the input element ids. There are inputs I need to use that have $ in the id <input id='field1$0'>. Trying to use the id selector $('#field1$0') fails (result is undefined).Is this a bug or "by design" in qQuery?Is there a workaround, other than looping thru all inputs to find the ones I need?

DOCTYPE Causes Form To Fail?

Aug 2, 2011

I had to add the following DOCTYPE to a webpage in order for IE to parse my page design properly, and this caused the form on the page to fail in FireFox (which works fine without the doctype). The form works fine in IE.Here is the DOCTYPE I added to the top of the page;

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

The error log in FireFox says;

frmTest is not defined - Line 30

Here is the block of code it is referring to;

Jquery :: Causing CSS To Fail Over SSL

Mar 29, 2010

I am using ASP.NET for data retrieval and jQuery to perform various functions/animations (error bar, slide menu, table sorter, etc...). Everything is working great until the pages are viewed over and SSL connection. When viewing over SSL, some of the margins/padding stops working and the hover effects on tables stop working correctly (leaving cells coloured, not colouring others). After spending a day looking for the solution in Google, I haven't found anything that will fix the issue. No errors/warnings are displayed on the page.

CreateElement And Nodes Fail In IE?

Jun 1, 2010

I'm having trouble parsing through a table in I.E. Of course it works fine in firefox and chrome. I'm pulling html off of a txt doc and storing it in a temporary div made with createElement so I can go through and parse out the data. Code is below:

[
Code:
var tempdiv = document.createElement("div"); //create temporary element to store html content in
tempdiv.innerHTML = html; //dump html content into new element

[Code]....

It returns 0 for rows and and cols. If I use a getElementsById and grab a table already on the page it works fine.

XmlHttpCreate Function Ie6 FAIL

Jul 12, 2010

I'm trying to GET or POST a request to a server. The code below works fine in Firefox, Safari, Chrome and IE7+ but fails in IE6 in spite of the xmlHttpCreate function being copied and pasted straight from Microsoft's MSDN site. The place where IE6 fails is on the oReq.send() line. It appears to create an activeX object but just won't send it. I have also tried oReq.send(null) and oReq.send("") but neither works.

Cookies Fail When Using URL Frame Re-direct

Apr 22, 2006

I have a simple html document I have been using for some time on my
(i.e.) abc.com domain that uses cookies. I recently purchased a new
domain name and set up a service to redirect my new domain (i.e.)
xyz.com to a sub-directory of the abc.com domain. In other words, when
someone goes to URL xyz.com, they really end up in abc.com/xyz
directory but the MSIE browser says they are xyz.com.

The problem is that cookies quit working in this setup when I copied
the same HTML document in the /xyz subdirectory that xyz.com now
accesses. I can't set or get a cookie any longer by calling the
document.cookie function from JS any longer. The call does not fail
but the data is always blank. I even tried setting the cookie and from
the next line of code reading it back immediately and it still would
not save the cookie.

Anyone know how to fix this?

I checked the value of location.host, .hostname .pathname,
document.domain and they all indicate I am really at abc.com even
though the address in my IE browser says I am at xyz.com.

Anchor Objects Referenced By Name Fail In IE?

Aug 7, 2010

for an anchor object, it is ok to reference by index. But when referenced by name, it seems unavailable in IE8 (not sure abt other IE version). I tried FF, it works well. So is it an IE bug or something?
<a name="thisAnchor">HERE</a>
<script language="javascript" type="text/javascript">
alert(document.anchors[0].nodeType)
// no problem in IE and FF
alert(document.anchors["thisAnchor"].nodeType)
// does't work in IE?

Ajax :: Firefox Call Fail ?

Mar 12, 2010

I have an Ajax call and it keeps return nothing versus some text when the ready state is 4, and the status is 0 inside Firefox 3.6.

I debug the server and it did return some text. The browser just doesn't expose it.

The JSP code is in a Weblogic server in port A, the JS code is included in the JSP coming from Weblogic port B (2nd server, same host). The Ajax call URL is on the same Weblogic server/port B as the JS. The Ajax call is started from a click on a button from the JSP page serving on port A).

Here are the configurations that works with the identical code:

1) Exactly like above using Internet Explorer

2) Exactly like above using Firefox, with the exception that the server is OC4J versus Weblogic

3) Exactly like the above (Weblogic), with the exception that the JSP and JS codes are in the same (single) server/port and using Firefox browser

So this is very strange. The same Weblogic server would work if all files are in a same server. In any case, the server code always work, and always return valid value (I wonder if some header is different). In fact IE works.

I think it's maybe security issue of Firefox handling of 2 servers. However, the same Firefox does work with OC4J servers.
