Loading in a bunch of json files from an array called bunchOfData. The .url is the url for each json file.
How do I read my variable "myI" in the processData function?
for(var i = 0; i < bunchOfData.length; i++){
$.getJSON(bunchOfData[i].url, {"myI":i}, function(ds){}).success(processData);
function processData(ds){
console.log(ds.myI); //undefined
}
}
function successHandler(i){
console.log('i is instantiated/stored in the closure scope:',i);
return function(data, textStatus, jqXHR){
// here, the server response and a reference to 'i'
console.log('i from the closure scope:',i, 'other values',data,textStatus,jqXHR);
}
}
var i = 0; i < bunchOfData.length; i++){
$.getJSON(bunchOfData[i].url, {"myI":i}, function(ds){}).success(successHandler(i));
}
return function(){ to return function(ds){.function handler(i){.You cannot access varibles outside of scope, the response will only be valid
function(ds){
// Here
}
Try this:
for(var i = 0; i < bunchOfData.length; i++){
$.getJSON(bunchOfData[i].url, {"myI":i}, function(ds){
console.log(ds);
});
}
Also once the request is finished and was successfull contents of success will run, note that what you are trying to achive can be dont with a single request (you can unify the files and serv them in a single one), so you get the data and then iterate.
console.log(ds); outputs the object and ds contains your data you just need to use the correct keys...
console.log(arguments)?myIvalue you sent insideprocessData?
