Removing Values From Querystring Before Being Sent Through Form (get Method)?

Jul 23, 2005

Just wondeing if there is a way to keep from having a certain
parameter sent when posting a form to another page (method=get)...

So as an example a page will post something like this from a form
using "get":

http://mypage?firstElement=1&secondElement=2

How can you completely remove "secondElement=2" from the
querystring... Before moving on to the posted page?

I know you can actually remove the element using removeChild in
javascript, and therefore it won't show up in the querystring of the
page posted to:

ochild.parentNode.removeChild(ochild);

But I was wondering if there was a way of doing it? A person can see
an inputbox for example disappear for a split second before the page
is posted... Is there a way of accessing the querystring itself in
javascript? Or some other way then removing the element?

Getting Values From Form Submitted With Post Method

Mar 2, 2006

I am having trouble finding a code example that uses javascript to get values from a form submitted on a previous page using the "POST" method. I've found some examples on how to parse the query string, but unfrotunately my form on the previous page has WAY too many charcters being submitted to be able to use the "GET" method (there is some upper limit here, I think it may be 255 or some number similar).

By the way this ONLY needs to work in IE, but it is better if it works in all browsers.

Number.toLongString() Method For Extremely Large Values

Feb 1, 2003

The standard Number.toString() method returns values in scientific notation once they exceed 10^20. In many cases, this is not an expected or desired result.

The toLongString() method provides a solution by always returning a literal numeric value regardless of the number's size. However, the value returned will not be accurate beyond the first [log base (radix) of (10^15)] digits.

radix: Optional. A number between 2 and 36, inclusive.Number.prototype.toLongString = function(){
var radix, n = this, d, t = '', p = ''
if(arguments.length>0 && typeof(arguments[0])=='number'){
radix = Math.round(arguments[0]);
if(radix<2) radix = 2;
if(radix>36) radix = 36;
} else {
radix = 10;
}
if(n < 0){
n *= -1;
p = '-'
}
while(n > radix){
d = n % radix;
n = (n-d)/radix;
t = d.toString(radix) + t;
}
return p + n.toString(radix) + t;
}

JQuery :: .submit() Passing No Values In Chrome When Method Is Post

Feb 5, 2010

I have tried to search for the answer to this, but came up empty. I am writing a form checker (and submit) in jQuery, and am testing with Chrome. Once I do my validation, if all is ok, I simply submit the form using...

$("form#courseForm").submit();
and here is my form tag.
<form name="courseForm" id="courseForm" action="courseDetail.asp" method="post">

In IE it works fine with either POST or GET methods in the form tag, but in Chrome it will only work with GET.When I try to use POST, the form does submit, but I don't get any data sent to the page at all. The only thing I am doing different than usual, is the form does not have a submit button. I am using a "button" tag and using jQuery to capture the click event. <button type='button' name='courseSubmit' class='blueButton'>Save Changes</button> why the POST isn't sending the data in Chrome? Simple workaround is to change it to a GET and it will always work, but I see that as a bandaid fix, and not really a solution to the problem.

JQuery :: Send 3 Text Box Values To Server Side Method Ajax?

Apr 14, 2010

I want to send three text box values to server using jquery ajax. problem is that, i dont know the exact syntax to send three data. When i try sending one data(also change no.of parameters to one at server side method), its going good but when i try to send three text box values, its giving jquery error:"Internal server error".

Below is the code:

function testCAll() {
$.ajax({
type: "POST",
url: "dbTest1.aspx/SendMessage",

JQuery :: Adding / Removing Form Field Elements?

Mar 29, 2009

I have just got myself a copy of SWFUpload to show the progress of file uploads, however, it has a few problems, one of which I am trying to fix with the aid of jQuery. Essentially, if JavaScript doesn't load, then a standard input file element will be shown. But, if JavaScript is enabled, then jQuery removes this, and replaces it with all of the input elements that SWFUpload requires. Is this the best way of doing it, or should I be looking at another option? If so, how would I go about telling jQuery to remove and insert the form field, and each and every attribute the HTML will require?

Querystring Maker

Nov 3, 2005

I helped someone out in the JS forum and it inspired this script which is quite handy for Ajax forms. Just pass the form object and it will return a querystring to attach to a url. Careful though, querystrings have limitations on the length of the string and it varies between browsers. Maybe there is something that does this already but I don't know of it.

function buildQuery(frm)
{
var ele=frm.elements;
var len=ele.length;
var str="?";
for(var i=0;i<len;i++)
{
var c_obj=ele[i]
if(!c_obj.disabled)
{
if(c_obj.name)
{
if(c_obj.type.toLowerCase()=="radio")
{
if(c_obj.checked)
{
str+=encodeURIComponent(c_obj.name)+"="+encodeURIComponent(c_obj.value)+"&";
}
}
else if(c_obj.type.toLowerCase()=="checkbox")
{
if(c_obj.checked)
{
if(c_obj.value)
{
c_val=c_obj.value;
}
else
{
c_val="on";
}
str+=encodeURIComponent(c_obj.name)+"="+encodeURIComponent(c_val)+"&";
}
}
else if(c_obj.tagName.toLowerCase()=="select")
{
if(c_obj.options.length>0)
{
if(c_obj.multiple)
{
var opt=c_obj.options;
var len2=opt.length;
var opt_group=encodeURIComponent(c_obj.name)+"=";
for(var j=0;j<len2;j++)
{
if(opt[j].selected)
{
if(j!=0)
{
if(opt[j].value)
{
opt_group+=","+encodeURIComponent(opt[j].value);
}
else
{
opt_group+=","+encodeURIComponent(opt[j].value);
}
}
else
{
if(opt[j].value)
{
opt_group+=encodeURIComponent(opt[j].value);
}
else
{
opt_group+=encodeURIComponent(opt[j].text);
}
}
}
}
str+=opt_group+"&"
}
else
{
if(c_obj.options[c_obj.selectedIndex].value)
{
str+=encodeURIComponent(c_obj.name)+"="+encodeURIComponent(c_obj.options[c_obj.selectedIndex].value)+"&";
}
else
{
str+=encodeURIComponent(c_obj.name)+"="+encodeURIComponent(c_obj.options[c_obj.selectedIndex].text)+"&";
}
}
}
}

How To Capture A Changes In The Querystring

Apr 30, 2006

Usually a change in the querystring causes a page reload and procedural code can can then run with the loading of a page. What I need to do is run code when links cause the browser to focus on an anchor.

For instance, I want to fire a script that prints to the screen every time the querystring changes via the following links: Code:

Seperate Concatenated Form Values - 4 Text Boxes That Are Supposed To Load 4 Seperate Values Of Data

Jan 27, 2010

I have 4 text boxes that are supposed to load 4 seperate values of data from one field in one table from a database. The field is called interface_cropsettings (from the interface table) and these values have been concatenated and comma seperated in this field.

Code:

Once the form is filled out and saved, the data is inserted into the database and the values from these 4 text boxes are concatenated, comma seperated and inserted into that one field correctly.

(Example)

If the 4 text boxes have the following values:

In the database field they become:

However, if the form is closed and then re-opened, each text box displays the entire database field rather then each value seperated in the corresponding text box.

(Example)

All 4 text boxes display this:

I already know why the data appears like this in the form, my problem is that I'm not sure how to write the javascript to seperate the values into the correct corresponding fields, assuming javascript is what I should be using!

Also, this is kind of irrelevant but just in case you're wondering, this form is part of a cold fusion application!
