I would like to create dynamic variable name and assign values to them.
Something like this:
I want to create these names dynamically.
I tried: var item{i} where i is the dynamic variable.
Nothing seems to be working.
I also tried:
It doesnt recognize : var eval('item'+i)
I have checkboxes which is generated within loop of records come from db and append the id with the name and id like this
<input type=checkbox name=CB.<?=$id?> name=CB.<?=$id?> >
Now in extension js file i want to check if check box is checked then create the variabel like CB1 (1 is the id) and the i want to assign value to this variable
i did something like this

//arrayLength is the no of check boxes
for(var i= 0 ; i <arrayLength; i++)

View 4 Replies View RelatedI'm trying to learn JavaScript on my own and am using a Dashcode example (if anybody uses Dashcode, the example is the "Browser" web application template that is shown when Dashcode opens).
Briefly, the JavaScript generates a list of "Locations" in the USA:
Code JavaScript:
// Sample data. Some applications may have static data like this, but most will want to use information fetched remotely via XMLHttpRequest.
var parks = [
[Code]....
I want to retain the layout and structure but, depending on the "Location" have different text for each of the new pages (not "the scenery is amazing etc).
I have a form where attachments can be added. Those attachment values will be wrapped into html code so it will be links. As they can click on a + sign to add more input fields, the amount of input fields is dynamic.
For each input tag there is, this value will be written to a hidden form field called "url" before it will be sent to the database.
Now it works and adds data to the database... but not for every form field apparently. Only for 1 new field..

I was wondering if it were possible to assign a PHP variable's value to that of a JS variable. What I mean is having a var in JS, and then making a PHP variable equal to the JS one.
Like this code...
Now of course, this file will be .php, and will be called as such when including it to a page (<script type="text/javascript" src="username.php").
The above code doesn't work... But I want to know if it can be done in such a manner. I just want a PHP variable to be equal to a variable in JS.
I'm Stephen Martin, an undergraduate Psychology student and researcher. Although I am a self-proclaimed tech geek, the extent of my knowledge ends abruptly at any sort of coding. The paradigm: I am currently investigating the decision making strategies in a particular population (I cannot reveal too much, lest our study be scooped by competing researchers in the field). The paradigm that we use is built through a package called MouseLabWeb [URL]. MLWeb basically provides an interface for researchers to create a html/php/js/css website that presents a grid (table). A small example is shown on the aforementioned website. The javascript functions allow each participant's events to be recorded, timestamped, and written to a MySQL database. This allows the researcher to know which cells the participant viewed, in what order, for how long, and ultimately to which decision the participant came.
Additionally, the PHP/HTML creates the table, but the data within it is populated by the javascript. This is a blessing and a curse. Here is why. The problem: The javascript offered by MLWeb allows the cells to be randomized. This is necessary, because in such paradigms, counter-balancing is required, otherwise there would be order effects (e.g., people tend to automatically read from the upper left) that are not controlled for. So the order of the columns and rows are randomized, the data which is then placed into the html/php table.
For the current study, we want the cells corresponding to particular types of information to be shaded differently. For example, we'd want cells that contain bad information to be dark, cells that contain neutral info to be grey, and cells that contain good information to be white. The problem is that setting these values (style="background-color: #XXXXX) only applies to the table as created by the PHP. It only affects the position, and does not consider the information that it is filled with.

I have a number of input boxes used to display totals based on
selected items for each row in a table. There are more than a few
rows that are identical, except for the form field name. I have added
a sample of that below (there would be many more rows).
I'm wondering if there is a way to dynamically generate the variable
names (ie: T1val, T2val, etc.) in my function 'calc', based on the
argument 'regnum' that I pass it. The problem right now, is that I
have to repeat lines 9 to 15 for every row that I add, using the
specific variable names for each. If there was some way to
dynamically create and assign them using the value of 'regnum'
(similar to using 'elements'), that would be great.
I guess one way might be to create hidden fields for each of those
variables, and I could then use the 'elements' syntax to assign
values, but wondered if there is a simpler way. Code:
If I assign an array to another variable, any changes to the array change both variables. Is it a pointer instead of a copy? Try this:
<script type="text/javascript">
Arr=['a','b','c'];
Arr2=Arr;
[code]....
Variables don't do this but it's happening for arrays in IE and FireFox, maybe all others.
Basically what I am doing is reading some values from a javascript that reads from an XML file. What I am trying to accomplish is a way to assign a variable that was declared within the "<% .. String strValue="" .... %>" section of my JSP page with a value returned from the script. Here is my code:
<HTML>
<BODY>
<%
String strValue = "NONE";
%>
......
<SCRIPT type="text/javascript">
xmlDoc=loadXMLDoc("customers.xml");
var x=xmlDoc.getElementsByTagName('name');
document.write(x[2].childNodes[0].nodeValue);
</SCRIPT>
</BODY>
</HTML>
As you can see in the above code the output of the script will be the 3rd node(starting from 0 to 2). I would like to assign the output of "x[2].childNodes[0].nodeValue" to the variable that was declared in the beginning "strValue".
I have tried different combinations but since the variable needs to be encapsulated with the "<% %>" notation because of JSP, I am stumped.

I have a form set up in which the end-user enters in the 'alexr2012' (form variable = sname) How do I change out the alexr2012 to sname so that the Data value is not hard coded ? that is - the data value is determine by the end-user entry ?
I have several lines of code in different functions where I need to refer to elements in document.form.max, so I figured I would define it as a global variable called tb1 to shorten the writing. The result however is the page senses an error as soon as it gets to tb1.value, of which I can't figure out why since things work when I change tb1 into a local variable. I was under the impression that global = full scope, so I'm not sure what's wrong here.[code]...
View 12 Replies View RelatedHow is it possible to take the value of a variable (in this case,
MODE_CREATE, MODE_UPDATE, etc) and use that as an object property name?
In the following example I want 'oIcon' object to have the properties:
mode1, mode2, and mode3.
This seems simple but I can't quite figure it out...
Any ideas anyone?
var MODE_CREATE = "mode1";
var MODE_UPDATE = "mode2";
var MODE_DELETE = "mode3";
var oIcon = {
MODE_CREATE: "create.gif"
, MODE_UPDATE: "update.gif"

var oTitle = {
MODE_CREATE: "Create a new item..."

I was wondering if anyone knew if/how to assign an event to
a global variable?
I tried to do it and IE 7 came back with an error saying "Member not
found"
My code looked similar to the following:
var globalEvevnt;
function showPopup(event){
globalEvent = event;
alert(globalEvent.type);
setTimeout(function(){unhideDiv()}, 2000 );
}
function unhideDiv(){
alert(globalEvent.type); //Member not found error found on this
line
}
I was wondering if I had declared the globalEvent = new Object();
would that make any difference? I thought everything in JS was an
object so the event could be stored to one as well?
