Is There A Way To Dynamically Assign A Variable Name??

Jul 20, 2005

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:

Dynamically Create Variable Names From A Loop?

Feb 11, 2010

I am working on a project where I need to redo the same thing with new variable names

Code JavaScript:
var paper1 = new Raphael('img1', 500, 500);
c1 = paper1.rect(0, 0, 50, 20, 5);
var paper2 = new Raphael('img2', 500, 500);
c2 = paper2.rect(0, 0, 50, 20, 5);

I would like to be able to do this with a for loop. So in the above example I would want paper+i, img+i, and c+i was trying eval("paper"+i) but didn't work.

Dynamically Assign <a Href> Value To <td> Data In A Loop?

Apr 20, 2010

I have an issue in dynamically assigning Onclick/<a href> action to the data within <td> cell.

Am pulling out data from a XML file, and displaying it as a table data on HTML page within a for loop. But within a loop, when am trying to do <a href> for the data by providing a dynamically changing URL value, the data is not getting displayed.

I donot know how to do it!! code...

In the code, name is the data element that am pulling from XML file.

On clicking each name, an URL should appear which has name as part of it.

For example, if the name is Kiran, then the URL will be 'Kiran.html'.

Is it possible to do it this way? Please suggest if there is any other way?Kiran.html

Possible To Assign Variable To PHP?

May 2, 2011

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.

Assign Array To Variable?

Oct 20, 2010

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.

Assign A Variable (JSP) From Within A Script

Oct 31, 2006

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.

Can't Assign Variable To Element

Feb 25, 2011

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]...

How To Assign Variable Value As The Object Property Name?

Jul 23, 2005

How 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"
, MODE_DELETE: "delete.gif"
};

var oTitle = {
MODE_CREATE: "Create a new item..."
, MODE_UPDATE: "Update this item..."
, MODE_DELETE: "Delete this item..."
};

Can I Assign An Event To A Global Variable?

Oct 4, 2007

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?
