what's the syntax for naming a variable on the fly? for example a for loop sitting inside a function:
for (var i = 0, j = divs.length; i < j; i++) {
"item"+i=whatever;
}
where "item"+i evaluates to item1, item2 etc...
I'd like the variables to be available outside of the for loop as well ....
I have three drop down menus that when changed call a simple js
function, passing a value i.e.
<SELECT name="Team" onChange="change('national');">
the function defined at the beginning is
function change(which) {
current = document.premForm.Team.selectedIndex;
document.images.premShirt.src = "assets/shirts/"
+document.premForm.Team[current].value + ".gif";
}
the var 'which' is being passed succesfully, but i can't work out how
to change
document.premForm.Team.selectedIndex;
into
document.whichForm.Team.selectedIndex;
depending on what value the function receives. My 3 forms are called
premForm,nationalForm and worldForm
Basically, i have a CSS/jQuery keyboard from NETTUTS; however my problem is trying to select multiple inputs. Everything works as it should, however i want to select the input, store it in hidden field (which input is current), then when i start to type, it can enter the characters into that input field (that is selected). Currently, it just allows me to enter inputs into a single textarea. I want to onfocus, set as "Focusedfield", and when i type it goes into that field.
Here is my JS code to select/store the "focusedField". Triggered by onFocus. to make the textArea i select, be the one i type into.
Code:
Here is the jQuery
The issue is with this first $write variable. I cannot for the life of me, get it to detect the dynamic variable. When i hardcode the inputs name, it works, but when i try something dynamic - it doesn't. Line 2 of that function is where my issue is (i believe).

I've tried to replace

With

And
Code:
As well as plain old JS var "current_form".
I think its just 1 or 2 lines where this issue is.
Ok i want to name an alert so that It can be called upon without being in a function. Code is as follows:
<html>
<head>
<title>
Sign In page
</title>
<script type="text/javascript">
function AccessText()
{
return document.getElementById("FirstName")
}
</script>
<script type="text/javascript">
{
window.alert("Welcome, "+document.getElementById("FirstName")+" you are signed in")
}
</script>
</head>
<body>
<form>
<input type="text" id="FirstName" value="Enter your first name">
<input type="button" value="Sign In" onclick="">
</form>
</body>
</html>
OK so how would I assign the window.alert a name?? So that I can access it with the onclick feature? Thank you.
I wrote a generic script to handle getting a cookie value, setting a cookie value, and replicating the $_GET request. I'm wondering what I should call a script that covers both cookies and URL requests.

I was peaking around on the W3C site to see if I could find a clear definition of which characters are allowed within an ID.The problem is that I have a series of divs that have id="aq-1234" "cd-456" etc. I have no real control over the - in the name. What would be another way of clearly identifying an object without the id? <td id="aq-1234"> is what I have now. I've not used the rel="xxx" that I see some people use. Would that be acceptable? Clearly $("#aq-1234") is not.
View 3 Replies View RelatedI've got an input with a value. The input is called 'command2' and I want to send it's value to the 'rover2' object (although I don't know if that object exists yet). I test and say if(rover2){... and if not then I create the object/if so then I insert the value.Question is: I want to do:Code JavaScript:var rover2 = new Rover();but I want to pass the name of the new object by association, so in effect:Code JavaScript:var "rover"+i = new Rover();How would you do that? So that the objects and their names are generated dynamically (or [perhaps a better explanation] so that the string value of a variable can be used as the name of new variable/object)?PS Bonus marks: If I hold HTML fragments as an object and those fragments include inputs, is the value of the input collected as well? i.e. if I have

I'm building a website that needs to be able to check the value of an
element and give it a new value based on what it's current value is.
So for example, if I had a product and my code read like this...
<input type="text" name="name" size="20"><br>
<input type="text" name="description" size="20"><br>
<select size="1" name="public">
<option value="1">on</option>
<option value="0">off</option>
</select>
Assuming the name of my form was "form", I could access the value of the
text fields by "window.document.form.FIELDNAME.value" and the select by
"window.document.form.public.selectedIndex". But the page i'm working with
has multiple products listed and so I've addopted a nming convention for the
elements name's so that I could access it more efficiently in PHP. So for
example, I'd have multiple products as such Code:
I have the following code which adds a dynamically created textbox to a form:
function addarow() {
if (count > 5) {return false}
count ++;

I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:
function show_video1(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
[Code]...
and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.
Ok, so I've built a member search using ajax to change the results each time a filter is changed. It works great, except one minor issue that I'm struggling with...I just can't specify dynamically in the parent file that linkclass$id opens linkclasscontent$id as I don't know of any way to pass that $id variable back over to the parent.

I have a set of different links, like:
<a href="link.com?page=text1">text 1</a>
<a href="link.com?page=text2">text 2</a>
<a href="link.com?page=text3">text 3</a>
etc, where page is dynamic and can be anything I chose..
Another place in the same document, I echo out what the page variable is, like:
echo "$page";
so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..
So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!
Is there any easy way to do this?
a.) specify two parameters for the changeYear function: today and holiday.
function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.

My problem is that in the external JS file (shown below) the loadTabs variable will not allow me to pass it a variable: contentDiv.onclick = this.initialiseContent; Whenever I pass a variable here it errors, am I setting this up correctly, should I be using prototype for my this. variables?
