View 2 Repliesthis is my first time posting on this forum. Hope you could help me. I am a beginner when it comes to Javascript. Here is my first stumbling block in this language.The code that works
if(x==1)
{
p1.value="x";
[code]....
I have a table that I populate with an array using ASP. As each row is created, the form object names are appended a numeric, such as:
i = 1
<select name="select<%=i%>">
...
...
...
i = i+1
next
I then pass "i" to a javascript function, so that I can access the values of each form object. I can't figure out how to properly concatenate the "i" and still allow access to the value in the form object. Currently I have:
var ps = 'platSymbol' + I;
alert(ps)
var sel = 'document.frmUpdPlatGrp.' + ps + '.value'
alert(sel)
I know I'm wrong, as this comes back as a complete string. Ultimately I want to have something like this:
var s = document.frmUpdPlatGrp.platSymbol2.value - so that I can actually get the value.
I need to create 14 javascript Ajax objects and assign properties and events to them. Since most of the code is just being repeated, I'd like to do the whole thing in a loop using an array for the object names. This is a portion of the code as it now stands:
boxe2_tree = new dhtmlXTreeObject("boxe2_div", "100%", "100%", 0);
boxe2_tree.enableCheckBoxes(1);
// etc.
boxe2_tree.loadXML("./xml/boxe.xml",function(){loadTree('boxe2_tree');});
warn2_tree = new dhtmlXTreeObject("warn2_div", "100%", "100%", 0);
warn2_tree.enableCheckBoxes(1);
[Code]...
Here's my problem: I need to create a variable name dynamically, made up of a string (say "var_name_") and an integer. Ultimately I want something like this:
var_name_1 = 'whatever value I want'
var_name_2 = 'whatever value I want'
var_name_3 = 'whatever value I want'
...
var_name_N = 'whatever value I want'
But the actual variable names are determined at run-time, so I can't just hardcode them.
Any suggestions? JavaScript doesn't seem to have a Variable type, so I can't just cast a string into a var...
I have a form with several types of checkboxes, and I'm trying to check all but one of them to determine if any of those have been checked. I do not want to check 'all', but I want to see if any of the 'check_' or 'check2_' checkboxes have been checked. There are a variable number of checkboxes, so this is just an example with two of each. Set 1 and Set 2 will always have the same number of checkboxes as each other, though.

I'm trying to use variable variable names using the window[] functionality. It works fine when you literally specify an array's base variable name, but I have a multidimensional array and would like to use window[] to build the name of the specific sub-array I'm looking for, like so:
// here's my multidimensional array
myArray = new Array();
myArray['id'] = 'foo';
myArray['sub'] = new Array();
[Code]....
However if temp is the name of a sub-array (e.g. 'myArray[sub]), and not the base array name(i.e. 'myArray'), then window[temp] evaluates to "undefined".
Can the window[] functionality handle this somehow, or do I have to resort to eval() or something else?
Have the Javascript function below which takes the name of an input on the form passed as a variable so that 1 function can check many inputs as I have up to 3 fields per form that can accept this data range.
function contact_number_check(formObj,field)
{
var obj = document.forms[formObj];
var regExp = /^([0-9 ])+$/;
alert(field);

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.
I am doing a project where I would like to be able to generate a series of variable names dynamically in the following example
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);
would like to use a loop to increment names
for (i=0;i<=5;i++)

Last evening I ran across this script which I think will address a need I have; replacing my radio buttons with images. The one difference I have is that I need to use a different button image for each of the 5 buttons in my group.Unfortunately, the script dose not apply unique classnames within the generated mark-up so if I'm to use this I need to apply some sort of counting variable that increments and use this variable to append the classname with.Around line 52/53 of jquery.checkbox.js is

I am trying to use a regEx to grab Function names and function parameter names from a text entry.
The script is written in javascript and I expect the functions to be in javascript syntax.
For example the code might look like:
Code:
function myFunction1(param1,param2,param3){
some code
}
function myFunction2();
function myFunction3(param);
Whats the best way to accomplish grabbing the function names and parameters?
Should I be breaking it down into multiple regular expressions?
I want to 'style' all links on my site with a variable for random colors. I got the variable for the random colors up and running but i can't figure out how to implement the variable to the css.
View 1 Replies View RelatedWhat happens is that when I click on a button, a random string from the RandomString variable appears below the button. e.g I click on the button and it displays 'AAB' and then if I click on the button again it may display 'AAE' and etc.
The problem is that sometimes it displays 'undefined'. I don't wanit 'undefined' to appear but why does it sometimes display 'undefined' rather than a Random string.

I'm trying to use Javascript to have an array of images that load randomly AND work in a slideshow manner so change every 3 seconds (in a logical order). The code I have below presents a random image but how do I get them to continue from the random image and change to the next every 3 seconds?
<script language="JavaScript">
images = new Array(3);
images[0] = "<a href = 'photo1.html'><img src='images/photo1.jpg' alt='Photo 1'></a>";
images[1] = "<a href = 'photo2.html'><img src='images/photo2.jpg' alt='Photo 2'></a>";
images[2] = "<a href = 'photo3.html'><img src='images/photo3.jpg' alt='Photo 3'></a>";

I've looked for a solution to this issue, but it seems like a little different scenario than other situations. I made a system for generating friend requests on Facebook. I have a grid that is 6 x 3, for a total of 18 cells. Each cell has a picture in it, and the picture is linked to the Facebook friend request page. My problem is that since each cell is populated at random from the array, I'm getting lots of repeats. For example, some picutures are in 5 cells, and some are in none. I'm trying to figure out how to make it so that once a picture is used once in the grid, it does not get used again in the same grid.I still want every cell filled at random on each page load, I just want to prevent the repeating.
Here's my current code:
<script type="text/javascript">
var vip_list=new Array(
new Array('http://profile.ak.fbcdn.net/v225/1616/88/s1220771654_2158.jpg','http://www.facebook.com/addfriend.php?id=1220771654'),

For my website I would like to create a famous last words generator (randomized), and random page generator (within my site). What is the code for random quotes and random links?
View 2 Replies View RelatedI am new to javascript but have been using java for quite a while. I am looking to make a random quote (out of ten possible quotes) appear in my h2 tag in a page i am working on. In java, i would make a random number generator, in javascript it looks like this:
Code:
var randomnumber=Math.floor(Math.random()*11)
Then make an if statement:
Code:
if randomnumber=1 {
var quote="Live long and prosper"
}
document.write(var quote); Could someone more experienced than me tell me if my code looks good and how would a go about getting "var quote" in my h2 tag?

Is their a way of iterating thru each tag within a form and returning the
value given in the id property, by that I mean the below html would return
the values idBoxOne, idBoxTwo, idBoxThree from the FormXX form.
<form name="FormXX" method="post" action="default.htm">
<input id="idBoxOne" name="bxOne" type="text">
<input id="idBoxTwo" name="bxTwo" type="text">
<input id="idBoxThree" name="bxThree" type="text">
</form>
Up to this point I've only used JavaScript to change CSS properties,
innerHTML and outerHTML so I'm rather new to the game.
I need to use a different type of name for a field in a form. does
anyone know how I can access this with this kind of name?
<input type="text" name ="id[txt_3]" size="6" maxlength="6" value="">
now how can I access this name in javascript?
//this doesn't work??
document.form_name.id[txt_3].value
document.form_name.?????????.value
I have a Javascript that gets data from an XML document and
displays it through javascript. The problem is that when I do
dcfile.getElementsByTagName("subhead")[0].firstChild.nodeName
all I get is #text. Can you tell me why? Code:
How do I iterate through an XML and get each tag name, without knowing in advance what these tag names are?
