I have the following code which returns h=30
instead of each value inside the loop.
for (var h = 0; h < 31; h++) {
$.getJSON('http://google.com/',
function(data) {
console.log('line ' + h);
}
)
};
What do I need to do to get loop values?
Make a closure with an IIFE
for (var h = 0; h < 31; h++) {
(function(h) {
$.getJSON('http://google.com/', function(data) {......
console.log('line ' + h);
})
})(h)
};
That way, the value of h
will be preserved for that iteration instead of being set to the last value by the time getJSON
is called back
