call

I'm reading Javascript Web Applications, from O'Reilly. At various points in the book, the author uses something along the following: instance.init.apply(instance, arguments); Does this make any sense? Isn't this exactly the same as: instance.init(arguments); .call() and .apply() are used to manually set the execution context of a function. Why should I use them when I'm intending to use the original execution context anyway? The point is that arguments is an array-like object. Doing ... instance.init(arguments); ... passes one argument, which is an array-like object containing certain

This is a little difficult to explain, but i'll try my best. This is similar to the code i'm currently running. function func1() { func2() } function func2() { exit(); } I need to be able to stop the execution of func1 from within func2, but I need a better way to do it than exit(). Since the caller of func1 might have other operations to do, I don't want to stop them as well, I just want to stop the rest of func1 from executing. I'm aware that I could put a simple if statement in func1 to detect the return value of func2 and then return if it's a certain value, but that's a bit messy too. So

I have a method that takes block of code as an argument. The problem is: how to test using RSpec if this method called the block? The block may be evaluated in any scope the method needs, not necessarily using a yield or block.call . It be passed to another class, or evaluated it in an anonymous class object or somewhere else. For the test to pass it is enough to evaluate the block somewhere as a result of the method call. Is there a way to test something like this using RSpec? See also this for more complex case with lets and mocks. rogerdpack I usually do something like a = 1 b.go { a = 2} a

I have a parameters array: $params[1] = 'param1'; $params[2] = 'param2'; $params[3] = 'param3'; ... $params[N] = 'paramN'; I have a caller to various functions: $method->$function( $params ); How can I parse the $params array, so multiple (and unlimited) parameters can be passed to any function: $method->$function( $params[1], $params[2], ..., $params[N] ); The idea is to utilize the url rewrite like this: http://domain.com/class/method/parameter/parameter/parameter/ ... You need to use call_user_func_array call_user_func_array( array($method, $function), $params); As of PHP 5.6 you can use

I executing a function like this, <script type="text/javascript"> $(document).ready(function() { getEntities("Clients/GetClients", 0, formatClientsResult); var maxvalues = $("#HfId").val(); $(".pager").pagination(maxvalues, { callback: getEntities("Clients/GetClients", formatClientsResult), current_page: 0, items_per_page: 5, num_display_entries: 5, next_text: 'Next', prev_text: 'Prev', num_edge_entries: 1 }); }); </script> $(function() { $.ajaxSetup({ contentType: 'application/json; charset=utf-8', global: false, async: false, dataType: 'json', beforeSend: function() { $('.loading').show(); }

This is for jailbroken iPhone. Is there a way I can access the call_history.db on iPhone which is a database where apple logs the phone call information. It is stored at /private/var/mobile/Library/CallHistory directory. When I try to enumerate directory paths under /private/var/mobile/Library it does not list CallHistory folder but everything else. I guess Apple does allow access somehow despite of having all the permissions. Is there a way I can get access to call_history.db and copy it under my app? I have already gone through another stackoverflow question here Accessing the iPhone's Call
