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.

I am undertaking an assignment where I have to create a webpage that reads values from a database, and generate the appropriate amount of sliders (scroll bars) according to the number of database entires. The webpage functions like this: On index.php load, it reads all the slider values from the database and automatically generates and sets each slider to that value On setting each individual slider to a new value by adjusting the slider, the code automatically updates the slider value in the database via AJAX.
So far I have gotten both functionalities to work successfully. There is just one problem with the 2nd functionality. I can only get one slider value to save to the database at a time. I know how to fix the problem, I just do not know to achieve it. I shall now illustrate via snippets of code:
how do i pass the values of listbox[] to javascript?
below is my javascript:
function Add() { Obj=(document.getElementById("scopeid[]")); alert(Obj.value); }
alert gives me only the last selected value and not the entire values. i.e if the user has selected 2 ,3 and 4th option, it gives me value of only 4th item instead of all three. how to do it?
I have got a following problem with using javascript:
I have a HTML page with pictures' thumbnails. After clicking on any thumbnail, I would like to open a new window with the original size picture. In the main window with thumbnails, I have got following important stuff: Code:
The scenario is : I have to fire an ajax request, get the json values and populate the page using jQuery template.
I'm able to fire the ajax request and in the success function I'm getting the data also. But I'm not sure how do I proceed with the Nested JSON data that I have received. I am passing it to the .tmpl() function but nothing seems to be working.
Here is the json data that I receive :
{ "activity": { "date": [ {
[Code]....
It also gives me an error sometimes that says "c.tmpl is not a function" which is linked to the jquery.tmpl.min.js .
I have a web page A that loads another page B using an iframe (or anobject tag), the B page is an external page (it's not on my server)and contains a form.I want to be able to auto fill the form with pre-defined values. Injquery i think it's impossible due to security reasons,I hope I explained the problem correctly, if you need more info just
I have a form which has a few submit buttons, all named SubmitButton so I can pass the clicked button's value through to the submission processor and then act according to which button is pressed. However on the jquery form submit even, I also want to check certain things before I fire the submission off. As the button isn't a "conventional" input I can't check the document object to see which one was clicked, so I need to check the form contents that are about to be submitted, can I do this from the submission event or will I have to bind to each button individually?
I have a selection list in my form. I also have an iframe in this document.
I am trying to access the selection list from my iframe as given below. It works in Firefox but not in IE.
var aaa = "navigator"; var bbb = aaa.appName; var selopt = ""; if(bbb == "Microsoft Internet Explorer") { selopt = parent.document.getElementById("select1"); - - - - - here i am able to get the object } else { selopt = parent.document.getElementsByName('select1')[0]; }
IE : var val = selopt.options[0].value; - - - - - - -here i am not getting the value.
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 have two Select Boxes on my web page, 2nd being populated based on selection of first select box. Now I am suppose to get the selected value of 2nd Select and put it in a link i.e. Code: <a href='abc.html?id=<2nd select box value>
I can get the selected value using Javascript with the following code: Code: 2ndid = form.2ndodf.options[form.2ndodf.options.selectedIndex].value; Where 2ndid is a global javascript variable. How I can use this variable into <a href> tag.
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
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 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?)
