Dynamically Append Form Data To A Post Request?
Dec 9, 2011
I am analyzing header tags for submitting forms online in order to better understand how htmlhttp forms work- signing in to gmail, yahoo mail, and amazon, using the network tab of google developer tools, to view the http headers of requests and responses, and learn where they come from. I am seeing very peculiar behavior in my browser's (chrome)request headers when signing into amazon. The form data, always has the following two header names appended to the second and third to last places of the form data query: x=(some random number), and y=(some random number).
There are no input tags getting dynamically generated,since when i tell google chrome to break on all subtree modifications, the site still sends off the post with the added parameters before anything gets modified, BEFORE crashing. There also is NO ajax call which is causing dynamically added data to be appended to the form post.My question is this: is there any way, using javascript, to instruct a browser, to append data as data, to a form post, WITHOUT the use of dynamically appended input elements, or ajax?

I have a form that submits a POST request when data is submitted.
A Servlet then processes this POST request and a JavaBean is used to make some calculations. The HTML response is not generated within the Servlet but instead I forward the request to a JSP to generate the response. - This all works fine.
However, I am stupidly suck trying to validate the form on the client side with a Javascript function before the form is submitted.
Here is my index.jps:
Regardless of whether incorrect input is given, the data is still POSTed to the server and calculated on or a Server Side error is given.
Am I correct in calling the function onclick?
The validation essentially needs to be so that:
- Student field contains a string
- Score1, Score2, Score3 and Score 4 contain a number between 0 and 100

I am doing a JSON request to get data back from a PHP file. On the return of that data, I am using a for loop to go through the data and post it up using JS. Here is my code:
for (var x = 0; x < data.length; x++) {
//create a container for each comment
var div = $("<div>").addClass("entry round").appendTo("#characters");
//add author name and comment to container
$("<div>").addClass("details").appendTo(div);
$("<span>").addClass("main-armory button").appendTo("div.details");
}
Now, what is happening, because there is 10 entries being posted, my JS is looking at the class that is being put together (main-armory button) and making it so that class appends every run through. So, I want one entry for main-armory button and I am getting this:
<div class="details"><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span></div>
And then, when it goes down to the next entry, it has 9 spans, and then the next entry has 8 spans, and it continues all the way down. What is going on here that I am missing? I know that I am not clearing a variable properly or something is wrong within my loop.

All Ajax libraries I've read use encodeURIComponent() on the name-value pairs extracted from forms before POST ing the result to the server with and xmlhttprequest. I can understand why this encoding is required in the case of a GET request and the form data is attached as a URI query string; however, why is the encoding necessary for POST requests?

I'm working with a form that has both static and dynamic form elements (add textbox, etc), and while I can access the static elements via request.form, the dynamic elements cannot be accessed. I have the dynamic elements appended within a div that lies within a table.
Here is the javascript:
Code:
function add3<%=strGoalCount%><%=strObjCount%>() {
var foo = document.getElementById('fooBar<%=strGoalCount%><%=strObjCount%>');
var numi = document.getElementById('theValue');
var num = (document.getElementById('theValue').value -1)+ 2;
[Code]....

can anybody help me in writing a javascript function which opens a
popup window with the target URL when the link "POST Request" is
clicked..
Points to note:
The HTML DOESNT and SHOULDNT HAVE A FORM TAG.
The URL data should be sent as POST and not GET..i.e the search
parameters should not be showin in the address bar when the page is
opened.
Sample code is:

I have a lot of tables and to get it to post some of the data into a form.
So say i have a location and a start date and end date, and when i select a radio and click submit the location and dates get put into the corresponding field in the form.
However i have a lot of tables and a lot of different options but want it to go to only one form. this form can be on a seperate page, but was wondering if its possible to get the form to appear on the same page, underneath the table.

I have a problem with sending data from a form to a php script with AJAX. To test if it works, I try to send data from the form, print it in the php with "echo", and then put it back in the initial html file.
My Javascript code is:
The function stateChanged, basically says:
The problem is that the response is empty, but I don't know why. I have checked the input data and the postData variable says "firstName="+input (e.g. "firstName=Robert"), so that's not the error.

I've got a form which is acting as a calculator. Once the calculation is complete I want it so when the user presses a 'print' button it takes certain parts of the form data and displays them in a new window which would be designed for printing.
how can i go about this using only javascript?

The server i'm trying to post data to in an ajax call expects data in xml format, including a particular attribute value. I have to use Chrome browser which does not support the XML Class (e4x).
I tried to marshal my data as follows:
But the ajax call does not appear to transfer the xml data to the server even though the xmlhttprequest call appears ok in Chrome's developer tool console.
I'm wondering whether I'm forming the xml formatted data correctly.

Very new to JavaScript so I'm sorry if this is a daft question, I have searched for answers first and could not find anything that works for me ... so .. One html form with two submit buttons. On submit (save changes) posts back to the same page and updates a database. The other submit button (preview) should open a op-up showing what the data would look like if the user should press save.

I have some forms whose ID's are dynamically created via PHP by including a variable called "invno" as shown here:
<form name="formEditInvoice<?php echo $invno ?>" id="formEditInvoice<?php echo $invno ?>" method="post" action="javascript: SubmitEditedInvoice(<?php echo $invno ?>);" onsubmit="javascript: return ValidateForm(this);">
As you can see in the "action" attribute, I'm calling this function:
function SubmitEditedInvoice(invno) {
$.post('output.php?mode=6&invno=' + invno, $('#formEditInvoice' + invno).serialize(),
function(output){[code]....
The problem I'm having is that no data is passed to the PHP back end. I have verified that the variable invno is correctly passed to the javascript function, and have tested my .serialize() by using a hard-coded form ID, but I still get no data passed through.

Is there a way to make a javascript post request to MyPage.aspx,
set a variable on MyPage.aspx, then do a javascript redirect to
MyPage.aspx and still sustain the value of the variable posted to the
page in the first place? As of now i'm successfully posting to my aspx
page, and successfully redirecting as well, but i have been
unsuccessful with sustaining that variable. I've tried using ViewState
as well as Session, neither seem to work exactly how i'd like.
Essencially, I'm trying to send a post request as well as redirect to
the same page Code:
