"Undefined" Array Error When Populating Dropdown Box?
May 10, 2009
I use ASP to write the arrays at the start of my page:
<script language="Javascript">
var ArrManu1 = new Array();
var ArrManu2 = new Array();
var ArrManu3 = new Array();
[Code]....
...to populate the second dropdown box. However, when the user selects the first option in the first dropdown box (therefore making the variable "Co" equal to 1), ((ManuArr[Co-1])[i-1]) is "undefined" - why doesn't it add "Bell" to the dropdown?
I am using Moodle and need to make an amendment in one of the modules using a little bit of Javascript.
I have an array called [[Loacation]] I want to create a dropdown in an HTML from which will populate from this array. I could probably just about do it in php using the foreach command, but I need to be able to do it clientside using Javascript.
I am getting some problems with populating my drop down boxes. I create the drop down through dom object.when I call this function onClick event in a button its work fine and populate the records from database so it does't matter how many times you click the button its work fine and populate all rows. The problem start when I call this function in a loop like in php file its populate only last row. but I want to populate all rows.
I am trying to populate inputs on a form from a select drop down list (with date being pulled from a mysql database). This is to allow for any changes that need to be possibly made.
Is this even possible? I've tried doing some internet research, and the books I picked up from the library don't seem to go into this at all, so I'm not even sure that what I want to do is possible. The only thing I can really seem to think is that i need to use onChange. But outside of that, i'm lost.
I have built myself an invoicing system and I am in the midst of upgrading it. Currently I have a dropdown box with all the items we sell in it and next to that a unit price text field. Currently you select the item and them manually type in the price. The issue is you have to know the price. What I want to do is once you choose an item it automatically adds the unit price. I am sure this is easy and have a funny feeling I have done this years ago. If anyone can point me in the right direction that would be great. An example or download code would be even better.
This is for a test, am not sure what they mean by "do not hard-code the resulting quarter years in the javascript":
instructions: When a user selects a date from the investment cycle drop-down box, the subsequent investment values must display the next three fiscal quarters.
E.g:
Do not hard-code the resulting quarter years in the javascript. (empahsis mine...;-)
The subsequent quarters should be presented with checkboxes which are all unchecked.
Checkboxes in markup:
The values to populate the checkboxes (value and label) have to be hardcoded somewhere, no? what am I missing?
The second menu is populating correctly from the first menu. The third menu doesn't work because it is not pulling the cat1 & cat2 values. I suspect it is the "checkNew" function, which I tried (with limited Javascript knowledge) to copy and alter from the "checkSelected" function.
I have 2 drop down list that are populated through mysql. They both contain data upon initial page load. However when you select an option from drop down #1 it populates drop down 2 with data associated to it. Sometimes the 2nd drop down list has selected data already and I need it to be cleared back to the first option when the first drop down is selected.
the following code is what I use to populate the second drop down
I am having a hard time figuring this out, I have two simple arrays and I want to populate one by asking a visitor to enter information, it goes something like this...
var country = new Array(5); c_list[0] = "USA"; c_list[1] = "UK"; c_list[2] = "France"; c_list[3] = "Germany";
[Code]....
how do I use a simple for loop to use the names entered and populate the second array?
I originally posted this question in the PHP forum and received advice to try here, they said it might be possible using JS and AJAX.I have limited experience with JS and none at all with AJAX.I have an HTML form in which I have a Select field, currently with about 100 options. The form creates an HTML email using formmail.Dependent on the option taken I get other details, eg address, email, telephone, etc.This is begging to be done via a database and PHP.I do not know if this is possible, but could I open the database, MYSQL, and take all the records into an array, open the HTML form and use one of the fields of the array to create the options list, when an option is selected use the other fields in the array to fill in the address, email, etc fields on the form and then use those values as variables to pass to formmail, which is a PHP program.
I thought that if this was possible I would use PHP to populate the array and then get it to call the HTML form where I could hopefully use the array to help complete some of the fields using SELECT.I would like to know if my thoughts are going in the right direction or if I need to go down another track.
I am populating a ‘Select’ object with data from an Array, and I succeed in load the page with the required data on the ‘Select’ dropdown list. But when I see the source code generated (view-source code) from the browser there is no option on the ‘Select’, you can see this form the browser source code:
And I want that appears the options generated in order to be able to talk with server, because server is waiting for some value (1, 2, 3 or 4). Now when I submit the form the server don’t recognize the option (value) received. So maybe the source code generated should be: Code:
Does anyone know why the onclick in the following popup menu gives the error:"Val is undefined"? Does it have something to do with the fact that it is called within the variable tablePop? Because it IS displayed properly as part of the popup text, where it is called outside the single quotation marks (see [***]). It is only in the onclick that it's causing problems. Code:
I am working on a site and have put some javascript in to control the size of the image that gets displayed on the page, however it runs ok but always returns an error after loading, and I can't find a cause. Code:
I've written a javascript function that checks for a php session. When there is no session, it works okay. But when there is a session, I get an "undefined" javascript error.
This is my js in question. I call sessionCheck() in body onLoad. If there is no session, I will get my alert of "it is null"
Code: function getUser() { return "<?php getSessionUser(); ?>"; }
I am trying to write a snippet to put in my form and cannot get it to run. I keep getting an undefined error for the variable 'Code' no matter what I do.The goal is present obtain a Time Frame based on an SVCode selected from a group of radio buttons.
I have a webpage that gives a quote (simple math). I recently revamped my entire website and when I went to place the page into the new site it will not work. It seems to not be doing anything at all. the page is at www.rwinvite.com/quote.html it uses quote.js which is in the same directory with the page. the html and js code is long, not complicated, but there are a lot of variables. This was working before I had the website redone, but I have no idea. I did run firebug and it tells me...
