JQuery :: Passing Value To Hidden Form Field?

Apr 2, 2010

I have a function that gets the value of a clicked on <span> like this:

function getSelectedValue(id) {
return $("#" + id).find("dt a span.value").html();
}

and sets the value of a second span like this:

$("#state").html("value: " + getSelectedValue("state"));

When I echo that second span, I get the selected value from the first span. But I need to get that value into a hidden html form field, so I can pass it along with the $_POST array. How do I do this?

JQuery :: Autocomplete Working - Get The Row ID Into Hidden Form Field

Dec 18, 2009

I have the official qQuery autocomplete plugin ( from bassistance) working properly. Start typing a product name and it queries my php script and mysql to return a list of products.

However, when the user submits the form, I want a hidden form field that contains the row ID for that product in the database table. I would have thought that this is a very common need, but I did not see any of the examples in the doc or website.

Can't Reset A Hidden Field In Form

Aug 12, 2007

i have a form in which a hidden field (initial value as &#390;', and my javascript set it to &#391;' when an event is trigged). In the same form, i have a reset field. But I realized that the hidden field is not reset to &#390;' when i push the
reset button. If I simply change the node from

"<input type="hidden" id='IsChanged' value=&#390;'>"
to

"<input type="text" id='IsChanged' value=&#390;'>"

Everything is working as expected (the value is reset to &#390;' when I
push the reset button) Why does this happen?

Using Hidden Form Field In Array For Validation

Mar 29, 2011

I have an order form where a customer can select a number of artwork prints supplied by different artists and suppliers. The name, price, postage amount and other details for each of the prints are held in a table in a MySQL database. As postage amount may vary between prints and suppliers of the prints we must have the customer select postage per print - not the amount just yes or no. The customer may select as many of these prints as he desires - printa, printb, printc, printd etc. through to printz. Many of the prints are provided by separate individual suppliers and must therefore have postage paid for each ordered print and this is automatically added by the order form. However some prints are provided by the same supplier and only one postage fee needs to be chosen (yes or no), so these are not automatically added and the customer must choose to pay postage on only one of the prints (not all 3 if he orders 3 of them).

So for postage purposes I have a postage code on the table in the MySQL database. For example printa, printb and printc are all supplied by the same supplier so each have a linked postage code of A. Similarly others may also be linked using different postage codes e.g. printx and printy may have a postage code of B. So whenever a customer chooses a print that does not have a linked postage code then the postage fee is automatically selected for him and charged to the total. However where prints are linked to the same postage code we must allow the costomer to select postage (yes or no), but we must force him to select yes or no for at least one of the linked prints.

So to do this I need a javascript validation alert to force the customer to choose yes for postage for at least one of the prints, not necessarily all of them, where they have a linked postage code. To do that I can add the the postage linked code as an array for each print selected to a form hidden field so that my javascript can use the field as follows: <input type="hidden" name="postagearray[]" value="<? echo $postagecode; ?>">

Posting A Hidden Field To A Form In A Document Using Javascript

Jul 23, 2005

I need to add an input hidden field to an existing form (post).

I have tried a couple things like adding the '<INPUT type=hidden
name=idSelectedURL value=http://server/documents>' to the innerHTML of
the form but it fails. ie

var sField = "<INPUT type=hidden name=idSelectedURL
value=http://server/documents>";
frm.innerHTML = frm.innerHTML + sField;


also, trying to add an element to the form such as:
var frm = document.getElementById("idForm");
var oField = frm.createElement ('input');
oField.type ="hidden";
oField.name = "idSelectedURL";
oField.value ="http://server/documents";

none of these work and give me a javascript error.

I don't think the createElement method can be used from the form
object, only from the document object. still could not get it working.

Passing Reference To Form From Non-input Field

May 27, 2004

I have a bunch of forms in my page, and want to pass a reference to the current form to a javascript function - when, say, a user clicks on a particular element. Normally, within any type of input field, I'd just add something like this:

onclick="my_function(this.form)"

Then, in my_function( form ) I could refer to form. No worries.

But here's the interesting bit. I also want to run the same function when the user clicks on any <a> tag within a form, like:

<a href="javascript: my_function(this.form)"> ... </a>

Problem is, with this code, the form reference isn't passed to the javascript function. the "this.form" bit doesn't work...

I find this rather curious. So the question is, how do I pass a reference to the current form from within a non input field?

Setting An Empty Hidden Div As The Value Of A Form Field And Then Calling Inline Div Opener ?

Jul 23, 2010

I'm setting an empty hidden div as the value of a form field and then calling inline div opener using thickbox.js:

Code:
<a href="#" onclick="javascript:document.getElementById('previewdiv').innerHTML = document.forms['form1'].content.value;tb_show('Preview','#TB_inline?height=550&width=500&inlineId=previewdiv');"><span class="icon-32-preview" title="Preview"></span>Preview</a>
<div id="previewdiv" name="previewdiv" style="display:none;"></div>

The thickbox opens with the title "Preview", but is empty.I've alerted the div after setting it, and it does contain the formfield value.Why might this be happening? I've also tried setting the div like this (foo as dummy text - to no avail):

Code:
$('#previewdiv').html('foo');

Linking Text Field To Hidden Field?

Apr 2, 2009

I have created a html purchase request form that people will fill out and submit to make purchase requests within my company. In this html form, I have a text field that is automatically populated when the page is pulled up. The text field is populated with the name of the person who is logged in and it is read only so they cannot be deceitful or anything.To get to this HTML Request form, you must log in through a webclient thus the server knows to populate your name because you are the one logged in. The text field populates because of its <input NAME = "OBProperty_CurrentUserRealName", which is a keyword the program identifies and knows to populate with the logged in users name into that particular text field.

That works all fine and dandy, so here is where the problem lies. When submitting the overall form request, the populated name isnt being saved/ carried over to the admin page so we do not know who it was submitted by.To make the persons name carry over and save, another field name keyword must be used.

Which is OBKey__163_1. Which it was suggested to me to make that the input name of a hidden field. I need "text field A" to continue to populate the form with the persons name using OBKey_CurrentUserRealName, then pass the persons name off to a hidden field containing the input name=OBKey__164_1, which will thus save/pass the persons name on with the rest of the filled out request form when its submitted.

Here is what I have:

<input name="OBProperty_CurrentUserRealName" type="text" id="buyer" style="width:100%" readonly="readonly">
<input name="OBKey__163_1" type="hidden" id="OBKey__163_1">

JQuery :: Changing Value Of Hidden Field Inconsistent?

May 29, 2010

I am working on bringing my existing website to the iphone/ipod using jqtouch and jquery.

I am stuck using the following code to change the value of a form's hidden field with the value of a clicked link. It works for the first two clicks then no matter what other link is clicked the form's hidden field value is changed to the value of the first or second clicked link?

Is there a more robust, reliable way of achieving my aim?

...$(document).ready(function(){ $('a[name]').click(function() { var str_id = $(this).attr("value"); $("#bookingperiod").val(str_id); }); });...<div class="info">Thu Jun 3rd 2010</div>
