Passing Variable To Function As A Literal?
Apr 24, 2010
I've been banging on this for a couple hours even though I'm sure it has a less-than-five-second fix. Hopefully somebody will glance at it and point out the obvious thing I'm missing.I'm using the onchange event of an html select element to trigger an array prototype function that looks for a value in an array and returns the indices of the array that contain that value, or FALSE if the array doesn't contain the value. For this example, here's the array being set up:
var instids = new Array();
instids[0] = 5;
instids[1] = 6;

I am having trouble passing the correct id to change the innerHTML. I have a jsp that display people and their address information. There could be several people in the list, so it is in a loop. That part all works good. There is a drop down list with countries in them. Based on the country they select, I want to change some of the text. Here is what I have:
<tr>
<td class="datashaded" valign="top"><font size="2"><b>Country:</b></font></td>
<td class="datashaded" valign="top">
[code]...
When I hardcoded the id= value, not matter which group I changed the country on, only the first one was changing, so I knew I needed unique ids for each group. There is more to the table, but this is the good part. When the onChange fires now, Nothing at all happens.

I have a function which is currently called twice on the same page. Part of the function is to apply an onkeyup event to a created element. The problem is that when the function is called twice the first created element calls the onkeyup function of the second element!
table_JD.length-1 = 0 for first element
table_JD.length-1 = 1 for second element
updateSearch_TC_JD(1) is somehow called from first element!
newSearchBox.onkeyup = function() {updateSearch_TC_JD(table_JD.length-1)}

So this is my dilemma. I'm creating a function and passing variables dynamically, but when I try to pass a variable and then alert it out, I get an 'undefined' error.

Here is the code:
for (var i = 0; i < BS_crm['activityTypes'].length; i++) {
var clickFunc = function(){ activityList.showForm( -1, {blockType:[""+BS_crm['activityTypes'][i]['id'], "0"]} ); };
var type = {
[Code]....
Now, basically what I am doing here is running through one array to create an array of objects, that will be used to create links that will use whatever onClick function I pass it. The problem is that on the second line I need the BS_crm['activityTypes'][i]['id'] to be a value, not a reference. If that line was simply changed to:
var clickFunc = function(){ activityList.showForm( -1, {blockType:["3", "0"]} ); };

I'm trying to make it so when you click a cell in a table it runs a function based on the value within that cell. With the current code, no matter what cell is clicked, the alert box displays the same number, which is the last number in my array. The variable, princ, is just being overwritten rather than writing code to each the cell with the proper value.
for(i=0;i<=3;i++){
document.writeln('<tr>');
document.writeln('<th>'+(periodArray[i])+'</th>');

I have a DOM click event that creates a <span>. When the user clicks a button, it turns that <span> into a textarea that the user can type a new name in, press enter, and then the span contains the text the user input. Sort of like when you rename a file in Windows Explorer.
Anyway, the code is something like this, and I'm wondering if I can use 'area_el' in this way... right now it's giving me the error that area_el is undefined, even though I define it in the function that contains the Event declaration.The first part is the Dom stuff to make it all work. It's not stuff I need to mess with, but I'm putting it here in case it's useful.
var Dom = {
get: function(el)
{

I'm using Keith Wood's jquery plugin to produce some graphs for my site. Though I've been able to produce "static" ones, I'd like the user to be able to input a new constant and then have my graph update it according to what they enter. I'm not quite sure how to add the value that the user inputs to my linear function below. So far I have:
Code:
<input type="text" size="1" id="plotit2" name="plotit2"/>
for the user to input the desired change. Then I have:
Code:
$('#plotIt1').click(function() {
var svg = $('#svgplot').svg('get');
svg.plot.noDraw().addFunction('lingraph', linear, 'blue', 3).redraw();
[code]...
I've parsed down the code to what I think are the important points but if I can clarify anything I'd be happy to do so.

I have a function in an external javascript file (calculate.js) which calculates the price of a product, based on a users preferences in a form (dropdowns, radio buttons etc). Each time the user modifies their choice, the script/function then displays the price on the page (index.html) using:
document.getElementById("price").innerHTML = price;
Once the user has finished making their choices, they then click the forms submit button (method="post") to be taken to a confirmation page (confirm.php).
Here, I can display the users preferences using php code like:
<?php echo $_POST['size'] ?>
<?php echo $_POST['color'] ?> etc, etc...
But I'm not sure how to pass the price over!
The preferences come from the form and are picked up with php. But the price is calculated with javascript! How do I send it to confirm.php?
I have tried adding
window.location = "confirm.php?Quote=" + price;
to the function, but this changes the page before the user may want to go to the confirmation page!
Can I add a hidden input to index.html with the value set as the javascript variable called price? If so, what syntax do I use for this? I have tried
document.write('<input type="hidden" name="quote" value="'price'" ?>" />')
and some other stuff too, but I still can't get it to work!
Or do I pass the value in the url, like confirm.php?Quote='price'? Again, what is the syntax, as I can't seem to get it to work?

I can't seem to get a variable declared from within a post callback, so that I could manipulate my script accordingly. I have delete.php, that deletes an id from a mysql db. If it fails, I want the script to stop and display the error. The .php script echos an "ok" if everything went fine, if not - it echos the error.var abort_error; // set the error variable
$.get("delete.php", { delete: $(this).parent().parent().parent().attr('id') },
function(data){
if(data != 'ok') {

Two objects on an html page. An event on object 1 effects object 2
$(".video_rg").mouseover(function(event){
var myTriggerId = event.target.id;
var myTargetId = 'video_' + myTriggerId;
document.getElementById(myTargetId).src = 'images/test_object_2.gif'; // this works
// $('#myTargetId').src = 'images/test_object_2.gif'; // this does not
});
My assumption (we know about those) is that I am not passing the data to the $() function correctly, that it is reading '#myTargetId' as a string, and not a variable. I just really want the JQuery code that would do what the document.getElementById code is doing.

I have the following code which attaches a function to events in x number of comboboxes (x will probably always = 4, but I do not want to hard-code this). I wish to pass the value of i to the function being attached as well as the value of tempData. In other words, I want the parameters in function to be the value, not a reference variable.
In the current example, I am using the hard-coded variable ci. This I want to be replaced by a literal created when the event handler is attached (the value of the loop variable i). Also, notice that I get the filter value in the event handler (assigned to the variable ct). I would like to replace this code with the value of tempData which would also be determined when the evenet is attached (it is the same value in this case, but it keeps the onChange event from having to do this each time it runs).
var props = {
col_0: "select",
col_1: "select",

Below is a stripped down example of code I'm using to count links in a
list. My intent with the ShowLinkNumber() function was to display the
number of the current link. (e.g. click on link 2, and the message "2"
pops up; click on link 4, and you see a "4.")
For reasons I can't trace, my function always displays the last number
in the list. Why does it do this, and can anyone suggest a way to
achieve my goal without adding markup? Code:

How do I start my literal object as a function like you do when you use the new Object method.
e.g. var fn = function(){ ...code...}
var func = new fn();
I'm trying to achieve this using the literal object method like:

what is the best way to setup one literal to be the prototype for another?So far I can only think of making a copy into a constructor.
Code JavaScript:

// the prototype for the new instance is set to the parent.
