I have a section of javascript that declares a global variable for a few functions, like this incomplete code
Code:
The above, in its full version, changes the text in a textarea. In my php code, if I include the above code above the textarea, it all works as expected.
The problem is that I may have more than one textarea - the number cannot be known beforehand. If I include the above before each textarea, the pointer gets confused as to which string belongs to which textarea since the global variables get redefined many times. In php, this would be a simple problem to solve with a mutildimensional array but, from what I understand, javascript doesn't have such arrays.
Someone can provide a solution that will allow me to use the same block of code over and over in the same file.
I'm kind of at a lose this is my first foray into using a multi-dimensional array and I've run into a snag. for some reason the second dimension always seems to end up being the last value of the second dimension of the array ie: in the case below the conditionArray[[0][1]] always ends up being 6.0 where it should be 1.0. Code:
Short version: I'm having trouble with "moving subarrays" in a multidimensional associative array.
Long version: (Yes, I know that there's technically no such thing as a js associative array and that I'm actually using a generic object.) This is one of those annoying questions for which significant code can't be shown.
I'm fetching a JSON object from PHP and parsing it as multi-dimensional associative array that comes out with this "structure": obj[regions][variables][years] = value; My presentation logic works fine for that. Year data is presented for each variable, and variables are grouped by region. For reference, if needed, the display is tabular and similar to this:
The value returned in the table is a 7 digit number eg: 1234567 This web view may have one, a few or a thousand records showing depending on the search criteria. For the life of me I cannot find a script that will pass all returned field values to an array that will allow me to remove duplicates and add a hotlink to the individual number and showing the result in a new view of the original table.
I'm trying to create a multi-dimensional associative array that has some of its data created dynamically. The code I've currently got is as follows (using JQuery to retrieve form element values):
Code JavaScript:
var data = { label: $('#label').val(), child_float: function() {
[code]....
.. if its values were not being created dynamically. However as you can tell that isn't what is being generated at the moment, as there's no opening/closing brace before/after the child_float's member variables. Any ideas what changes I need to make in order make the child_float behave as intended?
I'm having difficulty trying to return a multi-demensional array using Javascript Prototype's Hash Object.I have been able to return the values of the following associative php array using JSON and Javascript Prototype's Hash Object:
I would like to be able to pass a multi-dimensional Javascript array through a form to a server-side script I am running. Any suggestions as to how to do this? I know how to asign a Javascript variable to a hidden field (basic stuff ), and if it was a single-dimension array I would join() it, but I don't know how to treat a multi-dimensional array. Any suggestions?
and what I want to end up is with an array with the sum of the [0], [1] and [2] values, so for instance with this example, I want an array returned like this:
[50, 60, 52] i.e. this is [(32+8+10), (13+17+30), (26+4+22)]
My real problem with this is that the "inner array" can be any number of (its dynamic), so in my example its just 3 values but it could be for example 5 values e.g.:
I need to take the text in a textarea, split it into an array, and have the items in the array be added to a dropdown menu. When I try to split the value of the textarea (which, by the way, contains comma-delimited text) into an array, the array invariably ends up with only one item in it, and that item contains the entire contents of the textarea all jammed together with the commas removed.
The offending code:
Code:
In my test page, the text area (DownListTextBox) contains "yes,no" and when the alert fires it shows that the array has a length of 1. The Option added to the dropdown list has a text of "yesno". So, what did I do wrong?
I've written this javascript that puts lines of text into a readonly textarea, each line ends with a newline character. I have a function that checks that no duplicates exist, it does this by splitting the textarea by newlines into an array. This works as it should in Firefox, but not in IE. Code:
I have a pre-populated array in a JavaScript. How to populate TEXTAREA field with the text from that array, each entry on different line on page load? Say, value at index 1 will come at line 1; value at index 2 will come at line 2 and so on.

I am looking to have the user input a word into a textbox then when the user hits an "Add" button, the word is stored to an array and then is displayed in a table. I also want the textbox to clear after the "Add" button is pressed. Next, I want the user to be able to input another word into the textbox and when the "Add" button is pressed, have that word stored to same array as the first word but just to a different number.ingredient(0)=first word; ingredient(1)=second word. Then I want the second word to be displayed right below the first word in the table, in the next line down.This is what I have so far.[URL]...
I'm trying to add the text of a textarea form to the string that's contained at: myarray[a][b][c] It was easy to pull out the value of the textarea with this: textinput = $('#mytextarea').val(); But then when I try to add the variable into the array, it doesn't work. I'm not able (apparently) to do this. Fingers crossed that I'm doing something dumb?
This doesn't work: myarray[a][b][c] += newstringvariable; Nor this: myarray[a][b][c] = myarray[a][b][c] + textinput; I'm guessing there is a very simple (probably syntax related!) solution to this. I'm open to doing this via jQuery or regular javascript.
#1. I have a div with a class set that displays a border. I would like to set up that class so that when my mouse goes over the div it would turn the border color to yellow by changing the class.
#2. I would also like to be able to click on the element and return its innerHTML.
I have gotten #1 and #2 working perfectly in FF using a combination of CSS :Hover and addEventListener.
For IE I am trying to put the mouse over the DIV and changing the class to a specialized classHover that I have created, and when the mouse is out it reverts back to class.
Problem is it seems like the attatchEvent is trapping every single object on the page. So I end up getting a border around my page, my div tag, my p tag inside my div tag and so forth.
I've written a small javascript library to help automate Ajax requests and the like. One of the things I want the library to do is display a "Please wait" indicator in the upper right hand corner of the viewport while requests are processing.
What I do is append a div element to the document body, set it's position to fixed and set the top and right to 0. This works great in Firefox and Opera, but not in IE.
In IE this element displays in it's normal position (at the bottom of the page) as though it has a position: relative or position: static.
I've seen tricks using css and things like height: 100% and overflow- yL auto, but these never seem to work when I try them programmatically. And because I may want to distribute this, I don't want to require that the end user go through any gyrations for ths to work.
Is there a way of simulating a mouseclick in a div from a keypress?
In other words, if I press 2, I want it to simulate me actually having clicked in the div <div id="jplayer_next2"><a href="#">next</div>
Long version (for anyone wondering "WHY?")
Using the jplayer jquery plugin:
For some reason (and after 2 days I've given up trying to find out) I can't seem to directly call the function which is defined right there on the page:
function playListNext() { var index = (playItem+1 < myPlayList.length) ? playItem+1 : 0; if( index > 0 ) { playListChange( index );
I'm working on a project where I have to apply filtering as used on one table (using the jQuery datatables plugin) to a next table (which is using the picnet.table.filter plugin).
Now, I have been able to retrieve the values used to filter from the original table, and I have been able to put them as filterValues in the other table, but ..the table does not automatically filter correctly. I first have to press 'enter' (or add a space) to one of the values. when I do this, the filtering works perfectly.
My problem is, I want this filtering to be applied as soon as I open the page, since the heading of the table will be hidden, and the user is not supposed to have the opportunity to see or change the filter-boxes.
Does anyone know if there is an efficient way to simulate pressing enter using javascript?
