Help With 'return' Statement In Functions
Feb 4, 2006I have the following script:
function myFunc() {
// some code to do with AJAX
http_request.onreadystatechange = function() {
// do some things
return "a string";
}
}
alert(myFunc());
However, when I return "a string"; I want that string to be returned by myFunc() (and therefore alert'ed). What seems to be happening is that the string is being returned by the http_request.onreadystatechange = function() { } function, and myFunc() just returns false. How can I make the string be returned by myFunc()?
Calling Functions Using Forms

View 1 Replies View RelatedForms - Functions And Variable Declaration
May 28, 2009I have been having trouble with forms and functions. On my wife's site I have some forms and some of them have radio buttons. My current radio button checker is cumbersome and it is time for something more elegant (some of you will say if it isn't broke don't fix it )
The new code is below:
Code:
Basically I want to pass into the function radio button values 1 & 2 denoted by firstChoice and secondChoice (eventually I want to also pass in the form name but 1 step at a time).
The buttons can have the value (names?) of pattern, chalkboard or kit. It is for a shopping cart (Mal's E-commerce) and this is part of the JS validation. I am using onsubmit to call the function viz.
HTML Code:
Seems ok (to me at least) but when I try to get it to work it throws up an error of
Code:
It stops at that point but undoubtably chalkboard would throw up the same error if it continued.
How would I define the variables in my function? Are they strings, integers, who cares?
Where would I define them? Global or local?
Is the problem a matter of syntax e.g. if I put ' ' or " " around them would that suffice?
Var Statement In Doug Crockford's Scheme Functions Translations

Clear Checkbox Functions - Multiple Forms
Nov 2, 2011I posted a thread a few days ago concerning a bit of javascript code to make checking one checkbox clear another one. I got some great, prompt help. However, I just got back to working on that web page, and realized that the functions only work on the first form on my web page. I have many forms and they are actively named using php.
Here's are the functions (these works for just the first form on the page):
<script type="text/javascript">
function undo_Changes() {
if (document.getElementById("Complete").checked==true) {
document.getElementById("Needs_Change").checked=false;

Dynamic Forms And Updating On Reload, Inserting Functions, Jumping Text?
Jan 12, 2010I'm trying to create a dynamic form, and for the most part it's working out fine.I'm using javascript with onclick and onchange on checkboxes and select boxes to change the form as the user makes selections.However, there's a few issues I'm running into that are giving me problems.
One is that when the user reloads the page, all of the javascript inserted or removed form elements are reset, but the choices on the checkboxes and select boxes aren't, which looks very strange to the user. How can I avoid this? I'm currently including scripts tags in the body of the html, but this is pretty messy and hard to manage. Is there a better way? Second is that I'd like to be able to insert javascript function declarations into text that is dynamically inserted by javascript.However, when I do so, the browser does not recognize the functions. The reason I'd like to do so is that I am using Ruby on Rails, and would like to be able to keep the scripts in the partials to which they relate. I have to use inline javascript, because the scripts are having element ids inserted based on Ruby variables. Is this a lost cause, or is there a technique that enables dynamically inserted javascript to be loaded?
Lastly, my dynamic form's javascript shows or hides portions based on what it encounters while loading. The main reason is that I want to show the whole form for users without javascript, and then hide advanced or obscure details unless they are activated with a checkbox on the form for users with javascript. However, this is creating a jarring pop-in effect, where on first load, the pre-javascript formatted page is shown for a split second, and then the javascript kicks in and fixes everything and the page visibly jumps and changes. Is there a way to avoid this to create a more polished effect?
CSS And A Conditional Statement - Trigger The Fade-in/fade-out Functions Of The Span Class Is NOT Set To Active?

View 2 Replies View RelatedAdding Forms But It's Limited To Text Input Forms?
Nov 14, 2011how to add forms in javascript, but it's limited to text input forms.
<script type="text/javascript"><!--
function updatesum() {
document.form.sum.value = (document.form.sum1.value -0) + (document.form.sum2.value -0);
}
//--></script>
Where the inputs sum1 and sum2 are text fields you put whatever numbers you want in. That works fine. Great. Now what I'm having trouble with is modifying the code so that it will add one form with an input number with a form that spits out a randomly generated number.
<input type="button" value="D20" onclick="this.form.display.value = Math.round (20 * Math.random())" class="buttonHi" /> <input name="display" type="text" size="6" value="" />
This is what I'm using for my random number generator. So basically I want to be able to put, say, 5, into the input text field above this. And then click on the d20 button to get a random number, say, 15, and then have the first code add the inputted 5 with the randomly generated 15.
Getting Nested Functions To Work Within Functions?
Aug 20, 2009I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. :confused:
The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing.
function testWrapper()
{
function frequencyWrapperOne()

New Foo(); As A Statement?
May 12, 2007I am reading the ECMAScript specs trying to figure out if the next
line is a legal statement or not new Foo();
I think the above code may only be legal as an expression and not as a
stand alone statement. Would this make the above a bug?
Douglas Crockford's JSLint will choke on the above line of code and
stop parsing. All the browsers seem to accept it as ok and work as I
expect: the returned object just doesn't get assigned to anything.
The time I have used a line like the above is when the constructor has
side effects and the "class" keeps track of all its instances.
Any ideas what is right or wrong in this case?
IF Statement?
Jul 23, 2007I have several text fields on page that I would like to make calculations based on if there is a number input in one of the fields.
So, if the price field is populated, the sale price field would populate using a function to do the calculation.
Now, how do I write the code for this to occur? I know how to get the function to fire based on clicking a submit button, but not sure how to do it simply based on a number keyed into the one field. Is this possible and if so, how?
