In the attached code the outcome always defaults to the first test, even if the condition is false. How would I alter the syntax so that both condtions are evaluated?

if i group some javascript into a function that returns false; how could i carry that 'false' out of the function so it can be used outside the function.the example below shows the validate function checks for a condition then returns false if it is met. i want this false to then be passed out of the function to then throw an error in its containing function. (goal to prevent the submitting of a form)i dont want the proceed function to be called, so how can the other function prevent this.Now i realise that the validate function could be incorporated into the top level function but, my form will eventually be quite large with a multiplitude of fields so i need to know how i can call back to functions and use them as objects insteasd of repeating lots of code.

The fname and lname work fine but mi does nothing and I get no error is this because of the if statement or the fact that the mi only has one character?
I have on submit code that is checking to see if a field has any data. If not, some date fields are updated with generic data. The if statement does what I want it to do with the date fields, but it is overwritting what I have in the field that I am checking with either true or false. I don't understand why this would happen as I am not changing the value of this field with the code, just checking to see if there is a null/blank value.

I'm getting a value from the database either true/false. I have a alert box that shows it being true/false. I want a checkbox to be checked if true else not. Here is the line of code that I have and it just automatically checks everytime, which I obviously don't want.
$('#returnableCheckbox').attr('checked', $(selectedPlatform).find ('.equipmentReturnable').val())

Red part in the code above is for conditional statement.
But the conditional statement doesn't work correctly.
How can I make the conditional statement correct in javascript?
I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function.callback should be a string so why is it saying otherwise?

how to you use the result of a function as the argument for another function instead of passing the actual function to it. i.e.
function foo2(){}
function foo(func){}
foo(foo2);
This passes foo2 to foo, can I do foo(foo2()) ? i.e. is the difference between whether a function is passed or evaluated dependent on whether you use "()" after the function name?
I have two grids, they both display buttons. One grid displays numbers, true or false and yes or no, and the other grid displays letters, true, false, yes and no.
The second grid is not displayed in the code (used css to not display second grid buttons (.answerBtns)) Now using the getButtons() function, if the user selects button "1" in first grid (the grid which you have to open using (Open Grid) link, then it should display button "A" in second grid, if user selects button "2" in first grid, then it should displays buttons "A" and "B" in second grid, if "3" then display "A", "B" and "C" and so on.
Now except using if statements and stating which buttons should be displayed and not displayed depending on the button chosen in first grid, is there a more efficent way of coding this so that the display of buttons in second grid depends on what is selected in the first grid?
If it is using an array can somebody show a sample of this in their answer. You can just do it for one example and then I should be able to use that to fill it for the other buttons.
Is it possible to make a file insertion conditional? I now have the code:
'<script type="text/javascript" src="http://www.site.com/showit.js">'
And I wondered if it is possible to make this conditional, something like:
if (mycondition==true) include('http://www.site.com/showit.js');
if (form.interface_template.options.length > 0) {
template =
form.interface_template.options[form.interface_template.selectedIndex].value
} else {
template = ''
}
I want to write an if / then statement and have tried using this:
var MyVarMailto;
if (Request.Form("LoanRequest") == "Under $250,000") {
if (Request.Form("Organization") == "1") {
MyVarMailto = "emailA@address.com";
}
}
else if (Request.Form("LoanRequest") == "Over $250,000") {
if (Request.Form("Organization") == "1") {
MyVarMailto = "emailB@address.com";
}
}
else {
MyVarMailto = "emailC@address.com";
}
So basically I have a form that gets filled out and submitted which
passes the values to this page. I want to check the values against
conditions that you can probably figure out above and then set the
variable contigent to those values. I tried using AND after the first
condition but that doesn't do anything.
I have an table in which an select box like this:
Following have an option in OS: windows/Linux. i only want when user select OS - linux ... then function call otherwise if user select OS - window ... no need to call this function validate() i think it requires if condition in function Validate().... how it is posible to put if condition in function validate()
Currently have a txt input with default value="Your Name". with the on focus event to clear default text.
However if a user doesn't touch the txt box the the script goes on to validate the email box below because we have "Your Name" loaded up. and that passes validation below.
How do I go about adding another condition to look for string "Your Name" to the following if statement.
I tried adding another "||" statement after value.length <2 part and got nowhere.
function checkmailform(){
if ( (document.forms.newsletterform.Name.value == null) || (document.forms.newsletterform.Name.value.length < 2) ) {alert("Input First NewsName");
document.forms.newsletterform.Name.focus();
return false;
}else{...
Is there a way in javascript to use multiple if conditions? For example I need something like this: Code:
if( email=="" )
{
do something
}
elseif( !issemail(email) )
{
do something else
}
I know it would be possible to use else and then another if but since this javascript code is PHP-generated and I'd have about 5 conditions, I can't really do this easily.
I came across something I'm unfamiliar with -- there's an added check for window.location.href.indexOf("http")==-1 to see if the XMLHttpRequest send() completed, i.e.,
if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
Does anyone know why this is done or which browser this (kludge?) is meant for?
I created two forms. In the first frame i had Items with checkbox like
names of students etc. When ever i checked on any name It's display on
the other frame. Up to know it's fine. But when i deselcted any check
box it again display same name.
My requirement is when i deselected the checkbox that particular
student name is deleted from the list .
I am using jquery.validate.js for validating the forms.
The issue now is I have a dropdown list with values. Say a dropdown has the values 'One', 'two', 'Three', 'Four','Five'.
If the value is 'Three' OR 'Four' . The next 2 input fields are required. Else those are not required. The value will be seperated with optgroups.
I tried with different options but I couldnt find the solution. How to validate this?[code]...
Here is my code
