I am trying to pass two request parameters by ajax using jquery. The following is what I do:
function querySummary(){
$.ajax({
type:"POST",
url:"internalSummary.action",
data:{starttime:$("#starttime").val(),endtime:${"#endtime"}.val()},
success: function(data) {
$("#hello").html( data );
}
});
}
I am trying to pass starttime and endtime two parameters, but get
Uncaught SyntaxError: Unexpected token ILLEGAL
Can anyone give some suggestions on how to solve this?
Thanks alot!
You're using curly braces instead of parentheses on the second jquery select. data should be as follows:
{starttime:$("#starttime").val(),endtime:$("#endtime").val()}
The names of the values can be quoted or unquoted; javascript assumes they are names and not variables.

I have got a exercise for Ruby, and don't know how to make it! I'm still a newb, and learning my way in programming world, but I can't resolve this exercise. If you could also explain to me how you made it, that'd be great!
Here it is :
Write a method double on object account which returns the double of its input parameter num.
def account.double(num)
#your code here
end
# call double here
def account.double(num)
num*2
end
account.double(54)
In ruby, methods return value of the last statement if return value is not specified explicitly. Here num*2 is returned by the method.
We are calling account.double at the end of the program using 54 as the number. You can use any other number you like.
Just remember that the account object should be created, before this double method can be defined/called. I am leaving that to you as an exercise.

I have:
def is_valid_cool_string(str)
...
end
And I want to write something like is_valid_cool_string("Foobar") at the bottom of the file to do this. Is there like a main method or something like that?
Thanks!
You don't need anything to make this work. :)
Don't forget to print the result if the method returns something.
puts is_valid_cool_string("Foobar")
or something like
puts "Is valid: #{is_valid_cool_string("Foobar").inspect}"

<script type="text/javascript">
jwplayer('mediaspace').setup({
'flashplayer': 'http://www.vidok.co/s-static/v2/player-sp.swf',

Hi I need the xpath query to get the "file : http://www.vidok.co/cfs-ak-snc6/2012-12-17457.mp4" from this script.
Thank's
Here's an approach:
"substring-before(substring-after(/script, ''file': '),
''image'')"
And if you really want the "file : " at the beginning, use concat('file : ', theaboveexpression).
But if you ask me, XPath is not the best tool for this job.
Better to use something like regular expressions to parse the Javascript.

I want to create a method which will give me the user's full name.
the user has a first_name and a sur_name attribute.
I am trying to do something like
def fullname
"#{self.first_name} #{self.sure_name}"
end
but it gives me a method missing error when I try to do #user.fullname
am I missing something?
You have a typo: your method calls sure name (with an "e"), and you want sur name (without an "e").

I am trying to run Zapp from github, but it fails with multiple compile errors. But the compile errors are for pretty basic stuff, like the rowForView method cannot be found in a tableView object. I have not altered the build at all from the GitHub original download. Any ideas?
Zapp Group
/Users/cameron_geiser/Downloads/square-zapp-faa7f84/Zapp/ZappAppDelegate.m
Instance method '-rowForView:' not found (return type defaults to 'id')
Incompatible pointer to integer conversion initializing 'NSInteger' (aka 'long') with an expression of type 'id'
Use of undeclared identifier 'NSConfinementConcurrencyType'
/Users/cameron_geiser/Downloads/square-zapp-faa7f84/Zapp/ZappRepositoriesController.m
Instance method '-createDirectoryAtURL:withIntermediateDirectories:attributes:error:' not found (return type defaults to 'id')
Required Lion OS. Fixed the problem straight away.
