Making Form Elements Appear And Disappear
Jul 20, 2005
I have a case where the user can select several choices from my 1st <SELECT>
element. The user's choice on the 1st <SELECT> effects what the possible
choices are for the 2nd element. Currently the 2nd element is a <TEXT>
input, but I'd like to be able to make it a <TEXT> element when certain
items are selected from the 1st <SELECT> and a <SELECT> when other choices
are selected. Is there a way to either change an element from <TEXT> to
<SELECT> (and back), or to make a <SELECT> or <TEXT> element disappear
without re-writing the entire page?

I have absolutely no idea what is going on, but IE seems to be making random elements in my code disappear. Take a look at... [URL] and notice the login title and the forgot password link, you will notice that they look fine in firefox but disappear in IE. Does anyone know of any way to fix this mysterious error? I know there a lot of inline styles, they will be moved to the style sheets once all the bugs have been found.

I'd like the text in the search box to disappear when the box is clicked in. Easy, right? I've found several how-to pieces online, and gotten it to work with at least two different methods. However, I found a rather snotty discussion of form semantics that made me wonder: what's the right way to accomplish this, can I tighten up this code to be clean and tidy, and most importantly, can someone explain it to me so I can understand it? Forms tend to leave me confrazzled.

so there might be a simple solution to my problem, but here is my question: I have a box:
====html====
<div id="box">
<div id="innerbox">
<a href="" id="toggle"></a>
There is some text inside this box. It spans the entire width blah
blah blah.
</div>
</div>
[Code]....
I've thought of placing divs with a higher z-index next the main box but this isn't really an option, since it would make the website too large.

I am trying to create a fixed crest at the top of my site that changes depending on where the viewer of the site scrolls to.
I found the following script/plugin on StackOverflow that works well for making one element fade in and fade out.
PART ONE:
function isScrolledIntoView(elem) {
var docViewTop = $(window).scrollTop();
var docViewBottom = docViewTop + $(window).height();
var elemTop = $(elem).offset().top;
[Code].....
I then duplicated part two and changed the variables to make a different div appear in this position depending on where the viewer was in the site but it did not work past the first transition. see the following link to get a better idea what I am trying to achieve.
[URL]
Is there any way I can adjust the script to make it work with multiple transitions?

I have a list for example
<ul id="applications">
<li id="id-1" class="util"></li>
<li id="id-1" class="app"></li>
<li id="id-1" class="util"></li>
<li id="id-1" class="app"></li>
</ul>
Then I want a select some of the list with some animate effect, first the all of the elements would disappear, then the elements that I wanted would display one by one the code:
$('#applications li').each(function (index) {
setTimeout(function (e) {
e.hide("slow");
}, index * 100, $(this));
});
$('#applications li[class="app"]').each(function (index) {
setTimeout(function (e) {
e.fadeIn("fast");
}, index * 100, $(this));
});
The final effect is that all the elements would disappear first but the element I wanted would not display? Then I think about the queue,before I use it I change a little about the code:
$('#applications li').each(function (index) {
setTimeout(function (e) {
e.hide("slow");
}, index * 100, $(this));
});
$('#applications li')
.each(function (index) {
setTimeout(function (e) {
e.fadeIn("fast");
}, index * 100, $(this));
});
The yellow part is the different from the former one, the effect is that all the elements would disappear first, then all the would display again without any problem!

I have written a function to make visible elements with a certain id. however i intended it to be used to make visible multiple elements but it only appears to switch on the first element it comes to with that id. after that it appears to stop. i was wondering how i can adapt this function to make visible multiple elements, will i need a different way of referencing or can it be done through id?
function toggleLayer( layerID ) {
var style2 = document.getElementById( layerID );
if (style2.style.display == "block") {
style2.style.display = "none";
}
else {
style2.style.display = "block";
}
}

Basically i need help with input fields that when clicked the text (value) disappears but if the user has not entered anything in it would revert back to what was originally there.I have managed to get the value inside to disappear once clicked without the use of javascript but would love someone to point me in the right direction of how to revert the original value back if nothing was entered in if the user did click inside as the field continues to be blank.

What I need to do is create a dynamic select list using several sets of arrays.Example: fav color, fav car and fav genre.The trick is I need to use three radio buttons to control what is seen in the list.So if a user click radio button 1, the list changes values to one of the arrays.And if they click radio 2, the list changes to the values to another array.This is a learning process. I will really appreciate if anyone can help me on this.I can build the arrays, what I do not know how to do is make the list dynamic so that it fetches data from the arrays when a radio button is clicked.

Im working on my final project for my DOM and DHTML class and we have to make a calculator site. I have it working (for the most part). I was wondering If there was a way to make it so whenever the form finishes executing that the page wont reload, right now I have an alert pop up and say the result but I would like to have it put the result back into the form so the user can use it for other calculations. I didn't know if there was an easy way to do this, or what I would have to use, were allowed to use Prototype and Ajax, but I dont know how to use Ajax all that well...

I want to make a search form where inputs only appear if a certain selection has been made. For example the user selects "Green" then the input "X" appears, and if the user clicks "Black" then input "Y" appears. How can this be done? If so, can someone give me a basic example in code that I can use to copy off?

I have a form, its a very big form. About halfway down is a series of checkboxes (8 or so). Each one toggles whether the item I'm editing belongs to one of the categories or not. Each checkbox is linked to a subform that is invisible. (by subform I mean one or more form elements).
When a checkbox is clicked I want the subform to appear, and when it is unclicked I want it to disappear. Now the tricky part is, that when the page loads, it draws information from the database, and some of these checkboxes will already be clicked, so those forms need to be visible right from the start.
I'm just having far too many problems, can anyone point me towards some information that might help? Reply if I wasnt clear enough and you need clarification.

this is my first visit here so I would like to introduce myself.I`m Krystian :)I`m a newbie in Ajax, jQuery.
I've created a php file which contains form ( form.php ). This file is inserted after button click in index.php. In index.php I`m including jQuery library. My problem is that: when I`m trying the code below, just for test. This is not working. JS console doesn`t show any errors. Why such a simple code is not visible with form? When this example will work then I would like to code something much more difficult on this form. Best Regards Krystian. p.s. When I`ve created form directly in index.php alert occurs.$("select#numberPers").change(function(){ alert('you have changed the select option field');

I've been struggling trying to get a small order form to work the way I want it to. Here is a link to the live page: [URL] And here is the code in question:
[Code]...
I have two questions...
Question 1 How can I make this piece of script act a little smarter. Look at the order form, I'm catering for up to 4 people and providing lunch for them. If they select 3 people and the spaghetti bol for lunch, it's only adding $10 where it should be adding $30. Obviously this is simple multiplication but since the values in my form are prices it makes it a little tricky. I'm guessing an onselect on the first part of the form which changes the pricing of the other items would be the way to go, but how do I do this?
Question 2 The "Total Price" is placed before the <form> tag by the script. This is ok but it's not where I want it. How can I position this text elsewhere in the document?

I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.

I've put together what I think is an illustration of my problem at [URL] Quite simply, I need to be able to access the elements of the form without referring to them by ID as the whole form is intended to be cloned. I intended to do this using parentNode and childNodes[] together with the 'this' keyword. My understanding of 'this' in this context is that it should refer to the HTML element calling the function, i.e. one of the radio button inputs. However this gives the error "Error: this.parentNode is undefined"

Does "document.formName.elementName.disable" work on hidden form text
elements? I have a form with some input fields that are associated with
some hidden text fields and I would like to disable all of the
categories inside the form when the page loads and only enable each
category as it is needed. Code:

I have a grid that I'm adding rows to that include form text input boxes using addRowData. I know I can use the "editable:true" for that but I'd rather not at this time. Anyway I have the <div id=list1></div> surrounded by a <form></form>. Also statically I have a couple of text input boxes and a submit button. When I press the submit button the only parameters that show up in the POSTED data are the static ones. Is there a way to get the form elements "registered" with the form? I know I can always use javascript to extract the data and save it via an ajax call, but if there is a way to do it "correctly"
Example
var myRow = {id:"0",call:"<input name='callt"+boxNo+"' id='call"+boxNo+"' class='calls' type='text'/>",amount:"<input name='amt"+boxNo+"' id='amt"+boxNo+"' type='text' value='"+defaultDep+"'/>",residual:"",calculate:"<input type='button' class='buttons' id='b"+boxNo+"'/>"};
$("#list1").addRowData(boxNo,myRow);

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;
