JQuery :: Deleting Textarea Values From A Form?
Feb 9, 2010
I have a simple, three-field form that I am setting default values from within my jquery script. When a user clicks on a field the default values are removed, leaving that field blank for the user to type into.
The form accepts the default values from my jQuery script just fine. And when I click on the "to" and "from" fields, the default text is, in fact, removed. The problem is when I click on the textarea, the default value does not get removed.
Here is my html:
<form class="blogForm" name="blogForm">
<Input class="blogFormTo" type="text" name="email" />
<Input class="blogFormFrom" type="text" name="email" />
<textarea class="blogFormNote">

I have a form that has several disabled text fields. In these text
fields, I have initial values. Next to each text field lies a "copy"
button. When clicked, the content of the disabled text field is
appended to the content of another textfield, the only one that isn't
disabled (therefore the user can copy content from the other text
fields, and also add what they want). I also have a remove button,
which clears the content of that one non-disabled text field.
Pretty easy so far.
Here's the problem. Imagine I copy the content from textfield 1 into
the blank text field, then do the same for textfield 2 and 3.
Between each "insert", I've added a comma. So the non-disabled
(active) text field would have the following content:
content1, content2, content3,
Now say that the user wants to remove content2, without removing the
rest, how could I go about doing this?

I am making a mini wysiwyg editor for creating pdf letters which can be printed off.
In my editor is currently a html form which saves the textarea values each time the form is submitted. I want it to save to the database everytime its changed or maybe every few seconds.

After passing values, I cleared the form to start over and tried passing a new value but the previous values return with the new value. I hope that makes sense. Here's the code:

I have a form that gets values that a user has selected from a list menu field, that end up like this added to the URL:[url]
Instead of the Field being mentioned more than once, how can I have it where it could mention the field once with the values coma separated eg:[url]
Would I use JS to change the URL? or VBscript?

I'm handling a form submission event. Is there a way to modifiy the value of a text input within the form before the form is finally submitted? I tried setting the value using, 'val()' - it updated the text field but the value sent with the POST was the original value

This is my first time using the forums, so please excuse me if I do something wrong. On my website I am using jQuery 1.5.1 and the latest jQuery Form plugin. Wherever I have a textarea input, small inputs of less than about 10 characters fail to be sent to the server. For example, if I have a form: <form id="someform" method="post"> <textarea name="foo">

I'm trying to add the text of a textarea form to the string that's contained at:
myarray[a][b][c]
It was easy to pull out the value of the textarea with this:
textinput = $('#mytextarea').val();
But then when I try to add the variable into the array, it doesn't work. I'm not able (apparently) to do this. Fingers crossed that I'm doing something dumb?
This doesn't work:
myarray[a][b][c] += newstringvariable;
Nor this:
myarray[a][b][c] = myarray[a][b][c] + textinput;
I'm guessing there is a very simple (probably syntax related!) solution to this. I'm open to doing this via jQuery or regular javascript.

I am very new to jquery and I am trying to set the value of a textarea which is not in a form, into a hidden field which is in a form. In the text area, I have given it an id called refnote and ive used the text() to get the text in it. However, the problem is setting the retrieved text in a hidden form field.
$('form').submit(function(){
alert ($('#refnotes').text());
return false;
});

I want to do the following thing:
On a simple html page I included jQuery. The page contains a big form including text input fields as well as select list fields (with multiple values).
I want to combine the values from all fields (text and select list) into one (hidden) textarea.

I'm was able to successfully use your plugin for firefox, safari, chrome. When the form submits the request with file upload, here is the html I send back to the browser (via Rails): <textarea>{'status': 'success', 'avatar_url': '<%=@user.avatar.url(:medium)%>'}

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!

$(document).ready(function () {
var EmailXml = "<Set>";
EmailXml += "<Email>"
EmailXml +="<Type>0</Type>";
EmailXml +="<Addr>amol@gmail.com</Addr>";
[Code].....
Now I am trying to delete a node directly from above EmailXml , though it is possible with above code when case matches with my Type, I can do some string operations and get the result. But is there any other method which removes the node directly ?

I'm using jquery to pass trough data to another page where I want to insert and delete a record. But the problem is that jquery only inserts or deletes the records and not both together. I use following code:
For jquery:
$(document).ready(function(){
$("#btnAddPayment").click(payment);
});
//example 1
function payment(){
$.ajax({
type:"POST",
url: "acceptPaymentExecute.asp",
dataType: "application/x-www-form-urlencoded", .....
objRS = objConn.execute(strInsertPayment)
objRS = objConn.execute(strDeleteMemberPayment)
objRS.close()
set objRS = nothing
objConn.close()
set objConn = nothing
The queries work but not together. If I comment the insert statement, my page executes the delete statement. I already tried to call another object for my delete statement but it does the same.

I have some ajax functionality I have made, this basically creates an item in a database by an add button, the items are in a li.
I have a delete button span which when pressed shows a confirm or cancel buttons which are hidden initially, If i have more than one item in the list is will show and hide them on all the items in the list, heres the code
$('.source_delete').live('click', function(){
//Fade out delete button
$('.source_delete').fadeOut();
//Show confirm button
[Code]....
I need the show and hide not to apply to all items in list, the issue is im aware you cannot use live and each together, is this correct?? how can I go about doing this?

I have the following html and I'm trying to figure out how to delete the last rows the are children of div feed. I only want to leave a max of the first x rows. First I count them using $numdivs = $("#feed > div").size() - 1;. Then, I'm a bit lost on what to do next and have looked at the docs for children and thought of trying to traverse but can't seem to get it to work.
<body>
<div id="search">
</div>
<div id="feed">
<h2>Feed</h2>
<div id="firstrow" class="row"/>
<div id="1741946459" class="row">Test data for the first row</div>
<div id="1741946327" class="row">Test data for the second row</div>
<div id="1741939928" class="row">Test data for the blah row</div>
<div id="1741939928" class="row">Test data for the blah2 row</div>
<div id="1741939928" class="row">Test data for the blah3 row</div>
</div>

I have the following object:
var wDefaults = {
"skin":1,
"pagewidth":"960px",
"c1col":[
{"wid":"w001","pcol":0,"wpos":0,"wclosed":"false","wcollapsed":"true"}
],
"c3col":[
{"wid":"w002","pcol":0,"wpos":0,"wclosed":"false","wcollapsed":"false"},
{"wid":"w003","pcol":0,"wpos":1,"wclosed":"false","wcollapsed":"false"},
{"wid":"w004","pcol":0,"wpos":2,"wclosed":"false","wcollapsed":"false"},
{"wid":"w005","pcol":1,"wpos":0,"wclosed":"false","wcollapsed":"false"},
{"wid":"w006","pcol":1,"wpos":1,"wclosed":"false","wcollapsed":"false"},
{"wid":"w007","pcol":1,"wpos":2,"wclosed":"false","wcollapsed":"false"},
{"wid":"w008","pcol":1,"wpos":3,"wclosed":"false","wcollapsed":"false"},
{"wid":"w009","pcol":2,"wpos":0,"wclosed":"false","wcollapsed":"false"},
{"wid":"w010","pcol":2,"wpos":1,"wclosed":"false","wcollapsed":"false"}, {"wid":"w011","pcol":2,"wpos":2,"wclosed":"false","wcollapsed":"false"}
]}
First, how do I access a single value? I've tried some of the examples I saw on the forum, but nothing happened. The alert did not fire:
alert(wDefaults.c3col[0].wid); //first try
alert(wDefaults.c3col.0.wid); //second try
var obj = wDefaults.c3col[0]; //third try
alert(obj.wid);
The nested objects are the properties for widgets within a portal. After the user moves around the widgets, I need to update the object, putting the widgets in a different order within c3col and updating the values saved in pcol, wpos, wclosed, & wcollapsed. I also may need to add or delete an object, for example, delete wid=w003 and add a new one called w012.
My logic would be:
for each widget on the page
found = false
find the object in c3col where wid == x and update its other values
. set found = true
if found == false then add a new object to c3col with x & its properties
end for
for each object in c3col
if that wid isn't found in the list of widgets on the page, delete it from c3col
end for
sort the objects under c3col by pcol and then wpos
The red parts are the ones I'm unclear about how to do it. My basic questions are:
(1) How do you access a single nested object?
(an object within c3col, find and change its values)
(2) How do you add a new nested object to an existing object?
(add a new object to c3col)
(3) How do you delete an nested object?
(remove an object from c3col)
(4) How do you sort nested objects?
(sort the objects in c3col by pcol and wpos)
