var self= this; //parent function context/this
async.each(smpleArray, sampleFunc, function(err){
// if any of the saves produced an error, err would equal that error
});
This is sample function :
var sampleFunc= function(){
var self = this; //window object
//do something
}
I want to fetch the parent's this context inside child. But i am getting windows object there.
I tried:
async.each(smpleArray, sampleFunc, function(err){
// if any of the saves produced an error, err would equal that error
}.bind(this));
But its not working.
How to get the parent's self/this inside child function ?
You have to bind the context to the correct function, ie sampleFunc like this:
sampleFunc.bind(this)
So your example would be:
var sampleFunc = function () {
// this is set to parent function context/this
// do something
};
async.each(sampleArray, sampleFunc.bind(this), function (err) {
// if any of the saves produced an error, err would equal that error
});
