get

I'm experiencing a problem of $.get function. The url contains JSON my code: xyz = null $.get('http://www.someurl.com/123=json', function(data) { var xyz = data.positions[0].latitude; }); alert(xyz); //some more code using xyz variable I know that xyz will alert a null result because the $.get is asynchronous . So is there any way I can use the xyz outside this get function? The real answer is NO , but you can use this: function useXYZ(){ alert(xyz); } xyz = null $.get('http://www.someurl.com/123=json', function(data) { xyz = data.positions[0].latitude; useXYZ(); }); get is a shortcut. You can

This question already has an answer here: Difference between Property and Field in C# 3.0+ 10 answers I do not understand the difference between static properties: public static int intId; and get;set; properties: public int intId { get { return intId; } set { intId = value; } } What is the difference between these two? They work like same or different? Your first sample is a field, not a property. It's a good practice to always make fields private, and wrap them in properties instead. That way you can add validation on set or override property in descendants(if it is marked as virtual). Also

I am making jquery calls to get and getJSON, but cannot access returned values outside of callback function. How can I access the returned data? var firstid; var nextid; $.get(callUrl, function(data) { // call to add node var n = data.indexOf("id-"); var m = data.indexOf("id-"); firstid = data.substr(n+3,m - (n+3)); nextid = data.substr(m+3); alert("firstid:" + firstid); // returns correct value }); alert("firstid:" + firstid); // returns undefined for firstid how can I get firstid outside the function? ALL AJAX CALLS ARE ASYNCHRONOUS SO you need to use callbacks. anything outside that will

Hi i am looking at differences between $_GET and $_POST methods , i came across some articles that says A POST request also has $_GET parameters So a POST request is a superset of a GET request; you can use $_GET in a POST request, and it may even make sense to have parameters with the same name in $_POST and $_GET that mean different things. When should I use GET or POST method? What's the difference between them? http://www.sitepoint.com/on-get-and-post/ And there is an example also For example, let's say you have a form for editing an article. The article-id may be in the query string (and,

I am trying to get the automatically set Analytics clientId in Android. (Setting it is explained in the Android API documentation as setClientId() ) When I try to use tracker.get("clientId") it returns empty. Any idea anyone? Thanks in advance! I've ran a decompiler on it for you and it seems like the clientId property is stored with the key "&cid". Internally it does this: set("&cid", clientId); The solution would be to call this: tracker.get("&cid"); The get() method does however have special logic for the client ID key. It might also return a newly generated key or throw an

I'm working with an odata api, and when I'm using postman to do a GET request, works perfect and I get the response as I was expecting. But when I use a fetch request from my React app, the request throws a 401, using the same headers as I previously used in Postman. and it says that Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. The response had HTTP status code 401. Any idea about how to solve this request? Thanks! fetch('https://api4
