javascript - callback function for Google Geocode API not executing immediately -

-

I see this behavior when I move through this code: Response handler code is skipped when The rest of the function is finished, and then executes the handler code. It's definitely not what I want, because the code that comes after the response depends on the code in the response handle. 

  var geocoder = new google.maps.Geocoder (); Functional Initialize Place () {var Destination_Letleng; Var destination = document.getElementById ("destination_address"). value; Geocoder.geocode ({'address': destination}, function (result, status) {if (position == google.maps.GeocoderStatus.OK) {destination_LatLng = results [0] .geometry.location;} and if (position = = Google.maps.GeocoderStatus.ZERO_RESULTS) {Warning ("Bad Destination Address.");} And {Warning ("Error calling Google Geocode API.");}});

What is the reason for this behavior, and to ensure that I run the callback before the code given below, how can I change my code?

Geocode runs with asynchronous, so you have to keep that code inside the callback, or another callback Function must be created: 

  geocoder.geocode ({'address': destination}, function (result, status) {if (status == google.maps.GeocoderStatus.OK) {destination_LatLng = results [0] .geometry.location;} and if (condition == google.maps.GeocoderStatus.ZERO_RESULTS) {warnings ("bad destination address.");} And {warnings ("error extinguishing Google Geocode API.") }} // Keep more stuff here instead}};

or 

  Function more stuff () {// more stuff here} geocoder.geocode ({'address': destination}, function (result, status) {If (status == google.maps.GeocoderStatus.OK) {destination_LatLng = results [0 ] .geometry.location;} and if (position == google.maps.GeocoderStatus.ZERO_RESULTS) {warnings ("bad destination address.");} And {warnings ("Google Geocode API called error.");} More Stuff ();});

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
