Show / Hide Depending On Form Selection - How Best To Arrange Data
May 13, 2009
I have a big form which I'm tidying up by only showing elements when they become relevant, based on the currently selected input (eg to only show an option for 'waist size' when garment type 'jeans' has been selected). I've done this many times, and probably used a different approach each time, so I just wanted to see what other people do. It's currently along these lines: "If a particular option is selected, then show this element, otherwise hide it".
Code:
//the onclick handler
function checkViewType() {
//go through radio inputs in the cell and check what's clicked
document.getElementById('supplierOptions').style.display=radioCollection.supp.checked?"":"none";
document.getElementById('subCatOptions').style.display=radioCollection.subcat.checked?"":"none";
document.getElementById('subCatTimeOptions').style.display=radioCollection.subcat_sumtype_time.checked?"":"none";
document.getElementById('subCatSumOptions').style.display=radioCollection.subcat_sumtype_sum.checked?"":"none";
document.getElementById('subcat_weekmonth_span').innerHTML=radioCollection.subcat_time_week.checked?"week":"month";
}
But it's a big form, with lots of nested options, and some elements can be triggered visible by several different options. So I'm looking for an elegant way to handle this without a million if..elses. Perhaps an array of element ids and which elements are allowed visible when that's selected.
I have the following code that generates two dropdown boxes in a form, but I would like for the second to be hidden unless the first has 'Software problem' selected. Is it possible to do this?
I am setting up a contact form, and want to have a drop down box with a handful of options. Clicking one option should display fields to input username & password, whereas all others will not. So far, I've tried and (replacing 'none with 'block' for the option that is supposed to show the input fields) but neither does what I need it to. I'm fairly new to javascript, just muddling my way through with the aid of tutorials.
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 have a multipage form. I can put data entered in hidden form elements from previous pages. I want to show or hide table rows depending on this data value. For example, I collect a list of names in first form, but if some names are blank I dont want to show the table row associated with that name to collect more data. I have seen loads of code to toggle rows but cant find any which shows me how to toggle on a variable.
how one can show and hide a div element using a pulldown menu. i need the different selections in the pulldown menu to show hidden DIV elements on the page. this will be used in a system where i only have access to the template, so the only approach i can use is jquery. how to change it for the specific selectors i need.

I want to get javascript to show or hide a row in a table depending on whether a value is held by a variable collected in a mulitple part formmail. If only 1 adult fills in their name on the earlier form there is no need to show the row which asks him to agree to membership on a later form page. This is what Ive got so far<form name="frm3" method="post" action="bookingscript.php">
I am maintaining a site which is written in ASP. Now i have to create some new pages.
In one page we have a table with many rows. Now, I want to enable or disable(showing and hiding also) 2 rows of this table depending upon the value selected by the user from a drop down list.
I got a selection tag which pulls values from DB to populate,i want to hide or show related div/table based on the selection. now i got two confusions. how can i know what is selected coz the option tag value is coming from DB, also i never work with show/hide thingy. how can i achieve it?
I have a calculator that I want users to be able to select a radio option that will display the coresponding calculator and hide it when the other radio button is selected in other words I want to only have one visible div at a time. How would I do this?
Here is my Javascript:
HTML Code: <html> <head> <script type="text/javascript">
If the first radio button is selected, I only want all three buttons to be visible to the user.
If the second radio button is selected, I only want the "Edit Data" and "View Data" buttons to be visible.
If the third radio button is selected, I only want the "View Data" button to be visible.
Is it possible to accomplish this in Javascript? In particular, I want to continue using the "input type=submit" buttons without having to create my own.
I have 3 divs that contain radio with labels and beneath each radio button I would like to show/hide a form based on whether the radio is selected or not.
Code idea:
So if the radio1 input is selected this would show form1. Selecting radio2 input would hide any other forms (form1, form3) and show form 2 etc.
I got a table.Each row has a list of statuses.If status == yes, then several elements will be shown in the rowif status != yes, then hide those elements.Im not sure if I have made a good solution, but it seem to work ok (opera9.6, ff2, ie7)The status selector passes on a unique rowid, and itself. This way the js function can get the row, and the status of the selection. Then toggle various elements in that row.Only annoying thing is the way row elements are named and found. It kinda have to rely on some hard coding, but its ok I guess.Im not sure if its possibel to just call toggle( this ), and that way get to the elements in the row.

I want that a <div> element will show when yes is selected and when no it should be hidden. For show and hind i will use the functions from the jQuery UI. But I don't find a way to call the hide / show function when the selection change.
The radio selection: <input type="radio" name="lang_anz" value="1"> Yes<br> <input type="radio" name="lang_anz" value="0" checked="checked"> No<br> When I understand the documentation I can request the current value from the radio with: <script type="javascript"> $('input:radio[name=lang_anz]:checked').val(); </script>But how i can now call the show / hide function when I change the selection?
I'm pretty bad with Javascript, but I need to hide or show a snippet of text (could be inside a div without problems) based on the selection of a dropdown menu (<select>). If they choose anything with the word "Series" on it, I need to show the snippet. If they choose anything without "Series" on it, then the snippet needs to disappear. I should mention the snippet is part of a form, just a checkbox but that shouldn't be a problem I don't think.
I would like to submit a form depending on the success data of an ajax post.
Below is my jquery code; as you see #theform is the main form and before submitting the form I need to check the availability of the the date and time and the room using$.ajax. However it doesn't submit the main form if the date, time and the room is available.
required=["txtCal_Event_CalendarID","txt_TreatmentRoom","txtTreatmentID","txtTreatmentTypeID","datepicker1","datepicker2","timepicker1","timepicker2"]; emptyerror="Please fill out this field.";

I have a page I am working and I am having some trouble with: I need to show and hide areas based on a radio selection. I initally started using the show / hide feature in Jquery but the problem is the elements need to be removed but then put back if the user selects the radio buttonagain as it has form elements that have validaion on them. The validation is still trying to validate the form elements becuase they are still on the page but just not showing. This is the radio group the user makes the selection from:
I want to have several forms on one page that are not displayed until a selection is made from the category drop down box(select element). The form displayed will depend on the selection made. Here is the code I have so far.
I want to have several forms on one page that are not displayed until a selection is made from the category drop down box(select element). The form displayed will depend on the selection made.
<p>Put in list?</p> <select name="in_list"> <option value="yes">Yes</option> <option value="no">No</option> </select>
Some PHP code governs whether the "yes" or the "no" option in either menu gets the 'default' "selected="selected" showing, based on database information. For instance, in the first menu, if the page deals with a case where the the first "is_current" value is indeed current, then the PHP code will write the default "selected="selected" for "yes":
HTML Code: <select name="is_current"> <option value=yes" selected="selected">Yes</option> <option value=no">No</option> </select>
If the page deals with a case where the value isn't current, the selected="selected" code will be written for the "no" value instead. The same goes for the second select menu. Now, the logic of my situation requires that, if the user selects "Yes" in the first "is_current" drop-down, then only "Yes" should be available to select in the second "in_list" menu. Anyway, I don't know javascript very well, but I found a function that seemed to be able to do this.
Code: <script type="text/javascript"> (function () { function updateLevel() { var limit = Number(this.value); // find the next select element var selects = this.form.getElementsByTagName('select'); var select; for (var i = 0; i < selects.length; i++) { if (selects[i] === this && selects[i+1]) { select = selects[i+1]; break; .....
(Apparently the script has to be put or called just before the </body> tag at the end of the page.) Then the select menus are recast as:
<p>Put in list?</p> <select name="in_list"> <option value="1">Yes</option> <option value="2">No</option> </select>
Now this appears to work, up to a point. If the user selects "Yes" for the first "is_current" selection, then only "Yes" becomes available for selection in the second "in_list" menu. A posted value of "1" represents "yes", and a value of "2" represents "no". Except, in Firefox, the javascript somehow overrules the default selected="selected" code. That is, the source code in the browser is correct, but the javascript draws it incorrectly.
For instance, say the database/PHP has drawn selected="selected" for the value "yes" in the second menu. Even though I can see that the source code is OK in the browser, the javascript will make the browser show a "No" selection as the initial default. This happens in Firefox, though not in Safari, and I haven't tested other browsers yet. This may be obvious but I'm not sure of javascript.
Here is my dropdown menu: <select name="peeps"> <option value="Frank Tompson">Frank Tompson</option> <option value="Henry Wilson">Henry Wilson</option> <option value="Bill Kent">Bill Kent</option> <option value="Jessi McDonald"> Jessi McDonald</option> <option value="John Hays">John Hays</option> How can I make it so if I click on John Hays a JavaScript pop up will say Hello John Hays, and if I click on Bill Kent a popup will say hello Bill Kent and if I click on any other name nothing happens?
