Using Javascript / jQuery, I'm trying to produce a series of dropdowns ("<select>") that have their options filtered as the user selects from them.
For example:
DROPDOWNS
Field 1:
- value_1
- value_2
[Code]....
When a option is changed all the current entries are removed and only the allowed combinations added back in.
how to find which combinations are acceptable based on what has already been selected.
I have the requirement for.
filter the table with multiple columns there are 4 columns.
i.e 1>date 2> time 3>users 4>status.
here i got the filter for individual filter.
but i need the multiple filter.
eg:if i enter date and time, then the resultant table should be satisfies the given date and time entries. those rows only visible to the user.
1 Box holds 3 items, Complete box weighs 75g, each item 25g, customer chooses their own 3 combo items. This could be the same all the same item or 3 different items.
I need a script that will require the selections to make up 75g in order to continue the process. i.e customer can only continue when 3 items / 75g worth are selected.
Here is a short version, I have about 12 selectors at the moment and possible more will be created (if that matters).
<form name="cart_quantity" action="myProduct?action=add_product" method="post" enctype="multipart/form-data">
<
<div class="placeholder">
[Code]....
The section of the form is just the portion with selctors, there are other fields with radio buttons for color choice etc.
Is it possible in Javascript to detect if a browser supports a particular event listener? code...
View 1 Replies View RelatedI want to add more dropdown options which are dependent on previous options. Now I have "hand" and "loft". I want to add next option "model" How to add third dropdown option box?
Here is the code:
I have a drop down with alot of options say about 6000 cities and
districts. I need to select all options if user selects "All checkbox".
I use "on change" and a for loop to do this, but it takes a lot of time
to select all these options. Is there any faster way to select all
these options?
function selectAll()
{
var element = document.getElementById("location");
var length = document.getElementById("location").length;
for(var i=0; i<length; i++)
{
element.options[i].selected=true;
}
}
I have two dropdown lists, and I want to have each option from the first dropdown list to give the specific options on the second dropdown list. For instance,
<select name="module">
<option value="pic1.jpg>TM1</option>
<option value="pic2.jpg>TM2</option>
<option value="pic3.jpg>TM3</option>
[Code].....
Note: The option values are just examples, but each option must have a value in order for other things to work.
Here is what I need to do:
If TM1 is selected, only Box1 and Box 2 are available (Box3 is removed from the dropdown "location" list);
If TM2 is selected, only Box 2 is available (Box 1 and 3 are removed from the dropdown "location" list);
If TM3 is selected, all options in the dropdown "location" list are available.
I have two dropdown lists, and I want to have each option from the first dropdown list to give the specific options on the second dropdown list.Anyway, let me show you what I really want to do. Please see the code below. If you want to properly run this, please make six dummy images and name them as followed: silo_1_ empty.jpg, silo_2_empty.jpg, silo_3_empty.jpg, tm1.jpg, tm2.jpg, tm3.jpg.What I want to do next is to apply a restriction to the dropdown lists. For instance, if TM#1 is selected, only Silo1 can be selected from the LOCATIONS, and Silo2 and 3 will be removed from the option. If TM#2 is selected, Silo 2 and 3 can be selected and Silo 1 will be removed. TM#3 can be in all locations.
In total, there are 12 modules and 20 locations. Each module image can only appear in one location at a time, but the options to select a location are restricted.
I don't know how to evaluate the no-blank selections against each other from a form as follows: .
I have a form with 6 dropdown fields, each containing a selection of 30 options (the 30 options are the same for each dropdown list). The user needs to select 'one of the 30 options' from each dropdown selection, but each option they select must be unique (no duplicate selections) or it must be left blank. E.g. The user can select Option3 within "dropdown1", but must select a different option for the other dropdowns - OR leave them unselected.
I've come across this archive at [URL]. What I would like is to have it to have it include "days" as well. So lets say as of today (Apr 8th), when a user choose Apr, the dropdown for 'day' will have the options 01, 02, 03.....08. Another thing to note is that each month has different number of days in it. I've tried playing around for quite some time now...but so far no luck.
View 4 Replies View RelatedI have a product select page that is really slow to use because 6 dropdowns must be populated and the page reloads after selecting each box, to get the options for the next box.
I want to speed it up as follows:
1) User selects one of 50 products from a dropdown list.
2) Page reloads, and all the possible options for the remaining 5 dropdown boxes are now populated (ie. list options all stored client side)
3) User can freely input the remaining 5 dropdowns without the page reloading.
I am populating a number of Select boxes on the server-side with a large number of options. I'd like to get the response size down without taxing the client browser too much. What do you think is the most efficient way to approach this problem?
Here are some considerations: The option text/values do not change very often, but could potentially change in the future. The page that holds the select boxes should never be cached, there are other aspects of the page that need to remain fresh. Firebug with YSlow is saying that the primed cache size of the page is 300Kb with all the select dropdowns and options, if I remove the options, the primed cache size of the page is 80Kb. I am considering breaking out the text/value pairs for the select boxes into a separate file that is cache-able calling it "valueTextPairs.js" and referencing it with a query string and some sort of server-generated MD5 hash of the data, so that if any of the values change, the client's cached version will be replaced by the latest version. Like so:[URL]...
Provided I do this, I anticipate that the primed cache size of the page will be reduced down to 80Kb (which I like) -- however, before I take the plunge, I am curious what you all think the performance effect will be?
I know the number of bytes on the wire will be reduced, but will this put a lot of additional pressure on the client's browser because I'd need to traverse the name/value pairs and add the options to the select boxes dynamically on the client end? If it seems reasonable to do this, what jQuery approach would be the most efficient? $('#selectId').html(options) with options = one big string? Adding each child option to the select in a loop? Something else?
Some client end folks are using IE6 so I am trying to tax the browser as little as possible, while also reducing the size of each request, trying to find a happy medium..
I have been searching for hours and have not found what I am looking for. BUT, I have seen it before when I was NOT looking for it. haha!
Anyway, I am creating a form. And the form has an element that asks for "How Many Children?" followed by a dropdown from 1 to 6.
Well I would like to display another set of elements from 1 time to 6 times, based on their selection.
Name: ___ Age: ____ Sex:____
That will be displayed as many times as the user selects.
I'm looking for four level connected drop down boxes. Unlike all the scripts I have seen on the internet I need all the options to be available if nothing is selected in the previous drop down. So I want something like combination of connected drop downs and ordinary drop down. If the selection is made, display appropriate options in other drop downs... Hope I'm clear...

I'm using dreamweaver cs5 and I have created a page that have a table that can check or uncheck certain option in each row..in every column, there is a main button ('m planning to add function in the main button to be check all or uncheck all - but I did not managed to do it right...there are errors)
For example:
Pulau Pinang button, when user click, it will check/uncheck all option under Pulau Pinang...same goes to other columns. After selecting their option, user can submit their option using submit button (option chosen can be in different columns). My problem is, my submit and reset button is not functioning besides, I'm not able to make the main button to check or uncheck all option..
Below is my coding for reference:
PHP Code:
<!DOCTYPE ...> <html ...> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title> <style type="text/css"> body {
background-image: url(images/crop.jpg); margin-left: 130px; margin-top: 60px;
margin-right: 130px; margin-bottom: 100px; background-color: #FFF;
} body,td,th { font-size: 14px; color: #000; } </style> <script type="text/javascript"> function MM_swapImgRestore() {
//v3.0 var i,x,a=document.MM_sr; .....
I've tried also using below code for check all/uncheck button but it doesn't work:
PHP Code:
<form name="myform" action="checkboxes.asp" method="post">
<input type="checkbox" name="check_list" value="1">ASP<br>
<input type="checkbox" name="check_list" value="2">PHP<br>
<input type="checkbox" name="check_list" value="3">JavaScript<br>
<input type="checkbox" name="check_list" value="4">HTML<br>
<input type="checkbox" name="check_list" value="5">MySQL<br>
<input type="button" name="Check_All" value="Check All" onClick="CheckAll(document.myform.check_list)">
<input type="button" name="Un_CheckAll" value="Uncheck All" onClick="UnCheckAll(document.myform.check_list)">
I have a dropdown box with 2 options: Free or UpgradedI need to do 2 separate things depending on which one is chosen.If Free, then set the value in fourth text field to 9999else, set value in Fourth field to 5555.
<head>
<script type="text/javascript">
function calculate()
[code]...
So I have a dropdown box and when a certain option is pressed will show other fields... if not they stay hidden. However, I also need it to check a radio button that should remain showing.
Right now I have
<script type="text/javascript">
$(document).ready(function(){
$(".dnuHide").hide();
$(".dnuHide input").attr("disabled","disabled");
// If option Other is selected for institution type, show text field for Other
$("#region").change(function() {
var val = $(this).val();
$(".dnuHide input").attr("disabled",(val=="DNU")?"":"disabled");
(val=="DNU")?$(".dnuHide").show():$(".dnuHide").hide()
});
});
</script>
How would I modify that so I can also have ()Option 1 (*)Option 2 (already checked) change to (*)Option 1 ()Option 2
I have disable my firewall, virus software, google pop up allowed, ie6 popp
up checker disabled.
Is there an other one?

I am trying to adapt a script for use validating a drop-down menu in a form.
The script works fine in my lttle demo. In the head of the page I've got...
Code:
<script type="text/javascript">
function checkList() {
var testForm = document.testForm;
if (testForm.demoSelect[testForm.demoSelect.selectedIndex].value == "") {
alert("Please make a valid selection from the list.");
return false;
}
}
</script>
And then in the body...
HTML Code:
<form action="demo.php" method="post" name="testForm" id="testForm" onSubmit="return checkList();">
<p>
demo select menu
<select name="demoSelect" id="demoSelect">
<option value="" selected>Please Select</option>
<option value="1">Attrib1</option>
<option value="2">Attrib2</option>
<option value="3">Attrib3</option>
</select>
</p>
<p>Submit
<input type="submit" name="Submit" value="Submit">
</p>
</form>
No problem, works fine. The problem is that I am trying to apply this code to a PHP page in osCommerce where the name of the drop-down menu (i.e. demoSelect) is generated dynamically. It is only for use in one particular situation where I know the name of the drop-down menu is generated as id[1] but it wont work when I replace the demoSelect for id[1].
I'm only really beginner with JS but I guess it's because JavaScript identifies id[1] as an array? Is this right and any ideas how I can correctly identify my drop-down to JS?
I want to split the result from window.frames['data_frame'].document.location;, this in order to find out which page is currently opened in the specific frame. When I do it like this:
var source = window.frames['data_frame'].document.location;
// var source = "W3Schools is great!";
index_source = source.split('/');
IE gives an error that this method or property is not supported by this object. When I check it on the other var it is accepted. Is there anyway I can make this work? I already tried to do it with
document.getElementById().src etc.. but that is not very reliable.
I have a page working perfectly that passes up to 10-12k worth of data into a function via an 'onClick' event. That onClick is one of the <img..>'s attributes, directly. In case later that (dynamic) data gets larger, am I toying with potential problams because of some limit - either a limit in what can be passed into a JS function, or else a limit in the max num of characters allowed in an element's attribute(s)? What do you think is the reasonable amount that I can pass before things start to break? I may need to go up to 50k. 100k maybe, but I doubt that much.
View 6 Replies View RelatedI have created a javascript for form validation. But I want to add some more functions in it. Like it should allow only US zipcodes.

I have two different arrays with the same number of element. The 1st array holds the ID's and the 2nd one holds the Items....i want to use both of them in a Jquery autocomplete plugin.. showing the the 2nd one values but getting the value of the 1st arr.
I was wondering if there is a way to combine both in one in Javascript.
like Arr3 =[arr1, arr2] where i display arr2 elemnt and pass arr1 elements?
I've been messing around and searching about trying to find something which will only allow one of the hidden div's open at a time. When a new link is clicked, the last div open closes. Unfortuanatly I haven't found anything yet.
