Is there a way to retrieve the value returned by an asynchronous callback in the client-side of Meteor before the stack continues executing? Here is code snippet as an example:
var result=function(str){
Meteor.call("getSearch",str,function(err,res){
if (err)
throw new Error(err.message);
else
return res
});
};
var final=result(text);
console.log(final);
Any suggestions on how I can obtain the value of final before it is displayed? Thank you.
When working with asynchronous functions, the most straightforward approach to handling the result is within the callback function itself. For example, if you wish to output the result to the console, you would need to do something like this:
var handleResult = function(str){
Meteor.call("getSearch", str, function(err, res){
if (err)
throw new Error(err.message);
else
console.log(res); // instead of simply returning
});
};
handleResult(text);
In a more general scenario where you need to process the return value through a complex function, you can also call that function within the callback:
var myComplexFunction = function(arg) {
... // perform various operations
}
var handleResult = function(str){
Meteor.call("getSearch", str, function(err, res){
if (err)
throw new Error(err.message);
else
myComplexFunction(res);
});
};
handleResult(text);
