After thorough research, I found out the solution which worked for me as well.. open wamp/www/index.php. Change this line: $suppress_localhost = true; To : $suppress_localhost = false;
I’m not aware of anything built into JavaScript to reference local variables like that (though there probably should be considering all variables are internally referenced by strings). I’d suggest keeping all your variables in an object if you really need to access by string: var variables = { “j”: 1 }; alert(variables[“j”]); Update: It kind … Read more
No, only use this when you have a name conflict such as when a method parameter has the same name as an instance field that it is setting. It can be used at other times, but many of us feel that it simply adds unnecessary verbiage to the code.
There’s no need for a server if using PHP 5.5+ – it has a built-in server (http://www.php.net/manual/en/features.commandline.webserver.php) Just use: $ cd ~/public_html $ php -S localhost:8000
It’s an encoding problem. Your page.html file is in UTF-16 (although it contains an erroneous meta tag saying that it’s using UTF-8), but the jquery.js file isn’t (it’s either in ASCII, Windows-1252/ISO-8859-1, or UTF-8 — doesn’t really matter which, it sticks to the characters all of them have in common). I suggest correcting the encoding of … Read more
You’ve a couple of options. First, note that g in your example isn’t actually a local to the function (ie. not assigned within it), it’s a global (ie hasn’t been assigned to a local variable). This means that it will be looked up in the module the function is defined in. This is fortunate, as … Read more
Yes, this causes undefined behavior. The lambdas will reference stack-allocated objects that have gone out of scope. (Technically, as I understand it, the behavior is defined until the lambdas access a and/or b. If you never invoke the returned lambdas then there is no UB.) This is undefined behavior the same way that it’s undefined … Read more
The reason the code with local returns 0 is because $? “Expands to the exit status of the most recently executed foreground pipeline.” Thus $? is returning the success of local You can fix this behavior by separating the declaration of x from the initialization of x like so: $ fun() { local x; x=$(false); … Read more
The only use I can think of is to reduce the scope of function declarations: int main() { void doSomething(); doSomething(); return 0; } void otherFunc() { doSomething(); // ERROR, doSomething() not in scope } void doSomething() { … } Of course, there are much better solutions to this. If you need to hide a … Read more
There are no direct way to define subgrid with local data, but you can relatively easy implement the same behavior using subGridRowExpanded (Subgrid as Grid). What one need to do is just to get from some you internal structures the data for the subgrid by the rowid of the grid. For example if you would … Read more
