Hidden Fields Are Showing On Page?
Aug 11, 2009
I dynamically create a hidden form field with some javascript. It works fine, the field gets created and filled in with whatever the user types in the prompt popup. But even though I have specified type="hidden" it is still displaying the field contents at the bottom of my form.
var newvar = document.createElement('input');
newvar.setAttribute('name',varname);
newvar.setAttribute('type','hidden');
newvar.setAttribute('value',Prompt.show("Enter notes"));
document.mainform.appendChild(newvar);

I'm poking at a small "single page application" (SPA), ala TiddlyWiki,
to act as kind of a local, single-user version of Twitter (no real
application, except to familiarize myself with JavaScript). Right now
I'm using a hidden field to hold JSON, which is currently my flat-file
database of posts.
Is there a better way to store JSON data in a SPA other than hidden
fields? I'm Googling now to allay or confirm my concerns, but I'm
worried that there may be some upper limit to how much data you can cram
in the value of one.
I'm using JSON mostly because (a) I really prefer it to XML in
JavaScript applications, (b) it seems (key word, "seems") smart to
separate my post data from posts (so I can show n-number of posts at a
time), and (c) I really dislike parsing XML in JavaScript when JSON
seems like a viable alternative. (Though, given my size/space if JSON
isn't going to work, I'm not averse to using XML.)

I have multiple fields in a form with the same name. Lets call the fields with the same name "junk_array". My first field of junk_array is a input type=hidden. All the others fields in junk_array that follow are type=text. I can reference this first hidden field in IE with document.form.field[0].value. In, fact my form works absolutely wonderful in IE 6. However, netscape 4.7 does not recognize my first field in the array as the hidden field. Netscape sees the first visible text field as the first field in the array, subscript 0. What totally and utterly perplexes me, is that, from a previous thread, I can do this and get 9999 back in an alert
box in Netscape and IE. So, this proves Netscape doesn't have some evil code that disregards hidden fields. I guess...
<body onload="alert(document.myForm.test[0].value);">
<form name="myForm">
<input type="hidden" name="test" value="9999">
<input type="hidden" name="test" value="8888">
<input type="text" name="test" value="6">
<input type="text" name="test" value="3">
</form>
I even copied these fields directly below the opening <form> tag in my form and both Netscape and IE see the first hidden field as as
subscript 0.
However, my form is much more complicated. I have tables within tables and about 30 other fields. In my form I cannot for the life of me get Netscape to recognize the first hidden field of junk_array to zed as index 0.
Somehow, If I make the first type=hidden fields visible, netscape does work nicely. Why when I toggle type=hidden to type=text does Netscape cooperate. What is happening here? Anyone else have this problem with hidden fields in Netscape? I could post the code to my form but it is
big.

Basically, I have a parent div that is hidden on page load. Inside the div is a thumbnail that would reveal the entire div when you hover the mouse on the thumbnail.[URL]

I'm using input hidden control's value in the javascript function.
same code is working fine on all other browser except a specific
version of safari(i.e.: MAC OS 10.3.7 and Safari 1.2.4).
problem:
control's value is not getting displaying at the first time
when the page gets load, although the same piece of code would work if
I just refresh the page, strage.
declaration of hidden control:
<INPUT id="hSliders" type="hidden" runat="server">
javascript code which is calling the value of hSliders:
alert(document.Form1.hSliders.value)
this alert is showing nothing although it should display string.
i check the view source also control's value is getting populated.

I'm using a web form with php. I want, that when user clicks submit button and it will be an error (some fields will be empty) then I want it to show a little popup window... A simple javascript popup window generator don't fits me, because I have a php function:
Code:
<?php if( !$isHideForm ):
global $sErr ;
if( $sErr )
print "<br><a name='error'></a><center><font class='form_error' >
$sErr</font></center><br> HERE SHOULD BE MY AUTO POPUP WINDOW";
$starColor = $sErr ? "#ff0000" : "#000000";
$style=" class='form_text' "; ?>

I have the below code in an html page and, since I cannot change the hidden types to text (no control whatsoever on the form), I manually add the values in the code. Clients only need to press "Submit", which is the only visible part of the form on the screen, and they are then taken to a page outside of my website.
Code:
<FORM action="...................." method="post">
<input type="hidden" name="Charge" value="0,00">
<input type="hidden" name="MerchantCode" value=".....">
[Code]....
What I want to do is add two Text Fields in the html page where the above code is given to allow clients to add text and somehow "feed" this text to the values of the hidden fields Param1 and Param2. This way, the added text will show up in the page outside of my website where the clients are taken after they submit the form.

Sorry if I?m posting this in the wrong forum but I couldn?t figure out through an internet search if js is required for what I want to do. I have the below code in an html page and, since I cannot change the ?hidden? types to ?text? (no control whatsoever on the form), I manually add the values in the code. Clients only need to press "Submit", which is the only visible part of the form on the screen, and they are then taken to a page outside of my website.

I am trying to do something, which should be fairly easy. I have a link that is defined as:
<a href="javascript: doTemplates(<?php echo $toggle_templates; ?>);" title="Click to show/hide message templates.">
The php code simply echos either 1 or 0 depending if the templates should be shown. Then I have the following function, doTemplates() defined as:
function doTemplates(input)
{
document.write('<input type="hidden" name="showMessageTemplates" value="' + input + '" />');
document.send_msg.submit();
}
The problem is that when you click the link, the page simply reloads to a blank page with the only code being the hidden field. This is not what I want, I want the hidden field code to be passed along, and then for the form to submit. So, what should have is that the hidden field code is added, and then the form submits.

I have a form that has 50 text fields and a corresponding hidden field for each of these.
i.e. textfield1 hiddenfield1 etc. When the textfield has data entered it calls a script but I want the script to change the corresponding hidden field but am stuck as to how to do this.
I have the following function which gets called:
function addOptions(currentRole) {
document.addGroup.['use_role_'+currentRole].value='Y';
}
How to get this work work. Where I have ['use_role_'+currentRole] the currentRole should be replaced with the number (1 - 50) so as to change use_role_23 if currentRole is 23.

This is a question for anybody familiar with rich text editors. Does anybody know why hidden form fields always appear as visible text fields in IE and not firefox? Just curious if you have experienced this with any RTE you have used or developed.

I have a flash file that calls this JS function. It basically adds a number to a comma separated string. this works fine.
var select = "";
function selectCounty (cid){ select = cid + "," + select; }
The flash also calls this function to remove a value from the string. The removeVal() function works. though, the *select* variable is not reforming into a string. I'm missing how to then put the array into a form that this is part of.
function unSelectCounty (cid){
// split the *select* string into an array
var select_array = select.split(/,/);
// remove *cid* value from array
unselect = removeVal(select_array, cid);
// reset *select* var
select = "";
for (i=0;i<unselect.length;i++){ if (unselect[i] != ''){ select = unselect[i] + "," + select; } }
}
function removeVal(arr, valToRemove){
// Normalize to a string like !val!!val!!val!
var s = '!' + arr.join('!!') + '!'
// Remove targeted values with delimiters
s = s.replace(new RegExp('!' + valToRemove + '!', 'g'), '');
// Remove delimiter added to end in step 1
s = s.replace(/^!/, '');
// Remove delimiter added to start in step 1
s = s.replace(/!$/, '');
// Convert to array
return s.split('!!');
}
Please help with these two problems-
1) i cant get the *select* string in unSelectCounty() to reform correctly.
2) i am unsure what to write so that the value of *select* is passed in POST form array. it can accept it either as an array or a string.

I'm having a problem using javascript with a form. I'm using javascript to determine whether or not a person has selected "yes" or "no" from the select list. If "yes" is selected, the form is supposed to slide down and reveal two more fields. If "no" is selected, the form is supposed to slide back up hiding those two fields again.
When "yes" is selected, the form displays the two new fields properly. In Safari, it does the slideDown animation, yet in Firefox, the new form fields just suddenly display. If I select "no" again, nothing happens. The slideUp animation doesn't play. So currently I am having to use $("#parent1").hide(); to get the "no" to trigger.

so I am working on getting the file names that are uploaded through uploadify entered into a database table - I am using the method posted here . Supposedly after all the uploads complete, a hidden form field should be appended to my form (form1) with the name of the file that was just uploaded (in the onComplete call) - the problem is after the file is uploaded, I don't see any hidden form fields in the page source, and also the filename that is being returned is not the unique name (in the upload script). Here is the code:
