Select Values Of One Select Box Based On Values In Second?
Jan 9, 2010
I've got two select boxes with same options and same option values on my page, i want that whichever options a user selects from first box, should also get selected in second box. I need to get this done in Javascript or without using advance jquery methods.
I am working on a class registration system that requires students to register for a main class (101, 102 or 103). The student is supposed to select one main course as well as provide a second choice in case the first is not available. I have two dropdown select fields to capture data
1) Choice -1: 101 / 102 / 103 ( Student needs to select one - Reading the classID from classes table) 2) Choice -2: 101 / 102 / 103 ( If student selects 101 in Choice-1 then the only classes available under Choice-2 should be 102 or 103).
How can I accomplish the above? Further to this there are two fields on the form where I would like to auto populate based on what they have selected in Choice-1 and Choice-2.
For Example: If a parent selects choice1: 101 the child Choice1 field should autopopulate with 100. If a parent selects Choice2: 201 the child Choice2 field should autopopulate with 200
My mission: Open/collapse TD cells based on items selected in a list box. Getting no response from jQuery so I've done something wrong but cant quite get there. Listbox 'mainselect' contains option values that refer to names of TDs in a table. When a mainselect option is clicked, it will toggle to open or close the referenced TD list box by option value. Does hide/show make a TD 'blank' or actually set it's width to '0'? I want it to close, moving other cells left.
I'm trying to do something that is slightly complex and I can't find any relevant examples in the usual places,I'm pulling a list of projects (and their IDs) into a select:
So I created a javascript to get all the selected values in one variable ... But whtever I try the values don't come .. I tried alerting at different places and wht I see is tht it don't even go into the for loop ...
Code:
<SCRIPT> function content() { var retval = new Array(); for(i = 0; i < document.form100.state.length; i++)
i can't sucessfully get the values out of the <select> and <option> elements in my HTML page. This is really annoying because i am using the same code as i always use. And infact, it is identical to the code in a previous project (a Product Quote Calculator). It should work, but for some reason it doesn't. The Error Console is telling me that that element's value is "null". However, i have used the DOM Inspector, and it is not a null value (as the Value="3" is set - the DOM inspector also verifies this). There is another problem, but i'll leave that for another posting *grin*. I'll still be working on that one until someone gets back to me on this problem. Anyways...here's the code:
the code is actually a bit long, so i added it as an attachment. maybe it will fit into a post window.
<html> <title>Sketch Book v1.0</title> <head> <script Language="JavaScript"> var SketchDataFolder = "c:data.txt";
I have a form with a "results" list box for a sort user defined sort Lets say the values are:
Field 1 (ASC) Field 2 (ASC) Field 3 (DESC)
What I want to do is automatically select all these values before submitting the form so I can pass every list box value to the next form whether selected or not. Depending on the number of values in the list box I think I need something like this:
// COUNT OF ROWS FROM ZERO MYROWS = document.choiceForm.choiceBox.length MYROWS = MYROWS - 1
for (i = 0; i <= MYROWS; i++) { document.choiceForm.choiceBox. ?????????????????????? Code here <<<<
I'm trying to figure out what I'm doing wrong here. I have a select control and I'm trying to determine what index or value was selected and I can't seem to get it to work right. I'm sure it's something simple but I'm new at this.
Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
I have a HTML form containing multidimensional selects listing equipments and their quantitites. This allow the users to select the kind of equipment and quantitites they would like to book. Upon onChange select event I would like to parse the data into a multidimensional Javascript array in order to check equipment availability for booking. But I can't figure out how to parse and upon JS HTML DOM reference I am not even sure it's possible. Code:
I am populating a select box from ajax .. it is loading fine ..But when i submit the form then the value of select box is never passed .. As if there is no select filed on the form ..
Code:
<SCRIPT> function content() { var retval="abc";[code].....
So when I submit the form .. The county field is never passed on to next page .
I'm trying to read a select(dropdown) box from an HTML form along with all its options. My core requirement is to be able to read a select element with all its option and store it in some variable/node using one JS function. Use another JS function to pick the node and convert the values from node back to the options of select box.
We can probably make use of jQuery as well, provided it is supported by IE6.
I've searched everywhere for this but can't find it. How can I select a particular value in a select dropdown box using javascript? (I.E a select box has 5 values, how can I select the 3rd?)
I have a form with 3 <select> items in it.Each one is to allow only 1 item to be selectedThese are the variables for mySQL query through PHP. I have a js file that is called when one of the select elements changes.I want the .js file to pull the value of all 3 of the select elements even if its blank.I can handle the error checking in php, i just don't know JS.This is simple html for the select item(s) each is named different but similar syntax.
Code: <form name="viewData" class="shifty" > <label>Select a month for Points Awards:</label>
I already know that you can combine multiple attribute selectors, &&-style, by doing:
$("*[name='someName'][value='someValue']"); However, what I was wondering is, is there any way to combine multiple attribute selectors, ||-style, such that I could select: $("*[name='someName'][value='someValue']").add("*[name='someName'] [value='someOtherValue']");
I have searched the web and this forumn with no results. I need to replace the value in a second select menu with the value from the firts select menu. So if I select ACD from the first menu it should go thru all the option values in menu 2 and replace the '~' with 'Computing'
I would like to have a jsp page with a form consisting of several inputs and selects. When page loads for the first time, there is only one select (with values taken from database), but after clicking on link "add", the subsequent selects are added (using JavaScript and DOM). It seems to be pretty easy task, but I'm not sure how to populate the newly created select with data.
I have a web page that has a select box and a textbox to add data into the select box. What I want to do is when I enter some data say a "valid date" in the textbox and click on Add button it should copy the same to the textbox such that ,when I navigate to a different link in the web interface and visit the same page again, the value that I had entered earlier should remain in the select box and be visible.
I have been able to copy the data from the textbox to the select box, but when I revisit the same page the value entered earlier does not remain in the page. Once the values are stored in the select box, those values in the select box should be copied to a structure written in C language in the backend.Can anyone tell me how can I store the values entered during runtime in the select box using javascript.
I need to use Javascript or similar to do this, but not certain. I want to set up a form in HTML to sell photo prints. I'd like the user to be able to select a print size (eg 4x6 or 5x8 or 7x9) and as a result, two values are set:
1. the print size in text (eg Ɗ" x 6" print') 2. the price of the print (eg $5.00)
How do I code my form so that two values are set at once, and if the user changes their mind (eg selects 5x8), the two values are set again.
The function "addPhrase" is where i know i'm having the difficulty - so for now I've forced it to show one value only:
'// The form name is AMANDA
function addPhrase() { document.AMANDA.js_strMemberMail.value = document.AMANDA.js_strPreDefCatList.value + ", " ;}
What I think I want is to be able to build up a string of values and write them out to the textarea (hence the ", "). With the option that more can be added, without deleting what's currently there.
