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.
[Code]...
Long story short, I need a button that when clicked selects all of my check boxes. The entire form is check boxes.
The catch is that they all have different names, and altering them isn't an option at this point (too much other code depends on it).
Example:
Code:
<form name="myForm" action="processing.php" method="post">
<input type="checkbox" name="arandomname" />
<input type="checkbox" name="adifferentname" />
<input type="checkbox" name="unrelatednamehere" />
[Code]....
Also, I was hoping to find a way to make the "check all" button become the "uncheck all" button if all things are already checked (and vice versa), but I won't push my luck.
I wasn't sure if this should be considered Javascript or HTML since I'm not really sure where the solution lies.
I found a script on this forum that does almost what I want from this thread: [URL]. Instead of a dropdown, I'd like to have a list of names using check boxes, so that you have the option to send an email to one or all of the people. When you choose your selections and click submit, an outlook email will pop up with your selections in the to: field.
Here's the solution using a drop down, this works (and works well), but doesn't quite do what I need :
<form name="Contact_Us" id="contact" method="post" enctype="text/plain" onsubmit = "getEml()">
<fieldset id="selection">
Who would you would like to email:
<select name = "sel">
<option value="email1@email.com" >email 1</option>
<option value="email2@email.com" >email 2</option>
<option value="email3@email.com" >email 3</option>
</select>
<input type = "submit" value = "Submit the form">
</form>
<script type = "text/javascript">
function getEml() {
var emailaddress = document.Contact_Us.sel.value;
window.location = "mailto:" + emailaddress;
}
</script>
Is there a way to use checkboxes but to do the same thing?
<INPUT TYPE=CHECKBOX NAME="name1@email.com">name 1<BR>
<INPUT TYPE=CHECKBOX NAME="name2@email.com">name 2<BR>
<INPUT TYPE=CHECKBOX NAME="name3@email.com">name 3<BR>
Find it really hard to understand these random variable names and what they are doing,im sure the random variable names are pointers and counts

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);

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'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.

var paper2 = new Raphael('img2', 500, 500);
c2 = paper2.rect(0, 0, 50, 20, 5);
would like to use a loop to increment names

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 creating a form in which a checkbox is checked based on specific info from previous page.The info I am passing is the client ID (which is a number I can pass in the URL variable)In the form I have a list of clients (with checkboxes next to them)Now if you come from a specific client page the checkbox with the client name should be already checked since you are getting info regarding that client, with the option of selecting other clients..So how I get a specific checkbox checked based on a specific variable?
View 3 Replies View RelatedI 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:

function myFunction1(param1,param2,param3){
some code

function myFunction2();
function myFunction3(param);
Whats the best way to accomplish grabbing the function names and parameters?

of, but I can't get the simplest of tests working - example 1 of the

I had a rethink about my problem discussed in this [URL] thread, where the function won't run properly a second time if the page hasn't been reloaded. That one appears not to have a solution, and I was thinking that a reasonable plan B is the following:
a) test if the function has already been run since the page was loaded
b) if not, run the function
c) if it has, reload the page with the onClick, then run the function automatically on reloading.
the problem I envisage is will the page "remember" to run the function once it has been reloaded?Of course, it would be simpler to do it running the function automatically once the page loads, then just reloading if the test comes back that the function has been run already, but that wouldn't work for the first time you visit the page - it would start running straight away, whereas I want it to wait for that first click. Here's the page [URL] I'm working on, if you want to have a look.
I was putting some javascript in a form and doing my usual testing and swearing when the javascript did not run without an error message of any type and reverting the code back until it did run and adding code til it didn't.
Then it hit me - isn't there a better way - doesn't someone have a program or utility that will help debug Javascript ???
As I'm doing Javascript it is much harder to decode than the 30 year-old Fortran programs - they typically gave a line number and variable name that was missing.
When I did Basic before Visual Basic, the editor identified errors in real time as we typed. What is available for Javascript?
If I have to test my code on different Netscape versions, can I download and run those versions on the same computer or will it create conflicts? And if I had to test only one version which one should it be - which one has the most common elements to all the versions?
View 3 Replies View RelatedI am trying to check if my new window is open and if it is change the url.
This works until I use the x in the corner to close the window. At that
point i get an error when i try to open the window again. I believe that it
is because newWindow is still active. How do I close newWindow when it is
unloaded or closed by the x. If this is truely the problem.
function openWindow()
{
if (typeof (newWindow) == "undefined" || newWindow.open == false)
{
newWindow = window.open("http://www.yahoo.com","","width=400,height=400");
newWindow.focus();
return false;
}
else
{
newWindow.location.href = "http://www.msn.com"
}}
Here's my solution, seems a little redundant though.
function openWindow()
{
if (typeof (newWindow) == "undefined" || newWindow.open == false)
{
newWindow = window.open("http://www.yahoo.com","","width=400,height=400");
newWindow.focus();

else
{
newWindow.close()
newWindow = window.open("http://www.msn.com/","","width=400,height=400");
newWindow.focus();
return false;
}}
In this piece of code (common to a number of pages) I want to set focus to a second input field if there is one.
