How to make a JSP function to run only when called?

this one helps. The events in the webpage (onclick event for example) is executed client side when someone opens your webpage and clicks the button. The JSP scriplets are executed when the webpage is opened and their result is the actual page that the client receives. So your method executes ONLY when the page is loaded (and the JSP is compiled). The java code is not even visible in the webpage you generate. If you open it in browser and check the source you will see what I mean.

How to make sure a class function wont be called until another class function has been called first?


Tag : python , By : Ian Badcoe

help you fix your problem I have a class object that creates some data fields: , I think the most pythonic way would be to throw an exception:
def get_datalength(self):
    try:
        return self.data_length
    except AttributeError:
        raise AttributeError("No length call create_fields first")
@property
def datalength(self):
   return do_some_stuff(self.data_length)

How to make the calling function wait until the called function finishes execution in jquery?

Does that help About your second question: You don't get it att all what I've explain it to you, do you?
done() subscription callbacks are called when you resolve your defferred instance dfd. It is called almost the very moment you resolve it. So you are going to open your next dialog when you have recieved the data.
function dashboard_submit() {
     alert('Dashboard submit');
    var dfd = new $.Deferred();
    dashboard_name = 'ram';
     $("#d_name_modal_div").modal({
        backdrop: false
    });

    dfd.done(function(){
        var dn = $('#dashboard_name');
        dn.val('booooooo I recived the data now I can open the dialog');
        dn.text(dn.val());
        $("#d_name_modal_div").modal("show");
    });
    dfd.resolve();
    return dfd;
}

function wtf() {
    var dfd = $.Deferred();
    $('#d_name_modal_submit').on('click', function () {
        dashboard_name = $('#dashboard_name').val();
        alert(dashboard_name);
        if ( !$.trim(dashboard_name) ) {
            alert('Dashboard name is mandatory.');
            return false;
        } else {
            dfd.resolve();
            alert('success');
            return dfd;
        }
    });
} 


$('#add_to_dash').click(function (e) {

    alert('Add to dash start');
    dashboard_submit().done(function () {
        wtf();
    });
    alert('Add to dash end');
});

In C can a called function make the caller function return?


Tag : c , By : Tink

like below fixes the issue Such a thing is not possible in C, but you can get close.
The identifier __func__ is implicitly declared at the beginning of each function as
static const char __func__[];
void error_check_fun(const char *function, int code, int result);
#define error_check(code, result) error_check_fun(__func__, code, result);

Will enclosing the caller function and the called function inside process.nextTick make them asynchronous?


Tag : node.js , By : toma

around this issue No. If the startPolling() function is blocking, then putting it in nextTick() callback won't help. It will block the entire thread on the next tick of the event loop - but it will block it nonetheless.
Example:
function x() {
    fs.readFileSync('file');
}
x(); // <-- it blocks here
console.log('...');
function x() {
    pricess.nextTick(() => fs.readFileSync('file'));
}
x();
console.log('...');
// <-- it blocks here
// (end of file)

How to make variable of calling function known to called function (not as function argument)

I think the issue was by ths following , You can wrap the additioanl parameters in a "constructor function" like so:
getTestFun <- function(a) {

  Test_Fun <- function(x) {
   list(Score = exp(-a*(x - 2)^2) + exp(-(x - 6)^2/10) + 1/ (x^2 + 1),
   Pred = 0)
  }

  Test_Fun

}
Do_Opt=function () {

  a=2
  Test_Fun <- getTestFun(a)

  OPT_Res <- BayesianOptimization(Test_Fun,
                                  bounds = list(x = c(1, 3)),
                                  init_points = 2, n_iter = 1,
                                  acq = "ucb", kappa = 2.576, eps = 0.0,
                                  verbose = FALSE)
}
