this 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
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 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
Code JavaScript:
/* Wrapping all passed elements */ return this.each(function() {
OK so Ive been using jquery for a little bit now and love it. I am a ColdFusion developer. I have a need where I would like to present the user with a list of categories and the user can drag and drop to sort, but then I need to post this new sort order to the database. So I see there are a ton of cool drag & drop plugins for jquery. I understand how they work and I can get it to work as far as spitting out DIVS or spitting out ULs that can be sorted, but then what? So now they are sorted on my screen and not really part of the form. How do I translate that into something I can do a post to the database with? Do I do an AJAX call every time they drop an item and try to extrapolate the sort order on that item after they drop it? Do I populate a hidden form field with the constantly updating sort order list? MAybe a list of ID's? How does everyone else go about this this task? I'm sure there is more than one way and I'm sure this is a common task.
Code: var origGrp = ['James','Bill','Jennifer','Bob','Karen'];
replaced with something like this:
PHP Code:
var origGrp = [<? $sql="SELECT c.new_userid, c.fname, c.lname FROM ".$prefix."_club_users cu INNER JOIN ".$prefix."_users u ON cu.new_userid = c.new_userid
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.
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:
I'm sure I'm missing something basic, but I can't seem to find what I'm looking for. If I have an xml doc where the parent node and child nodes contain elements with the same name ("name" in this case), how would I go about just getting the client's name? Here is a slimmed down version of the structure:
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.
for my gallery I am using the fallowing HTML. The Images are defined as '1.jpg', '2.jpg', '3.jpg' etc.I would like to change it to 'text.jpg'. However, when I change the image names, thumbnail names and the HTML, I only have a loading screen. So there seems to be a part of the JS which needs to be changed. Any idea how to do that?
