POExplaining jQuery AJAX Success Method
text
Body
copied!<p>Im trying to use this jQuery script and this is confusing me:</p> <pre><code>function CallService() { $.ajax({ type : varType, //GET or POST or PUT or DELETE verb url : varUrl, // Location of the service data : varData, //Data sent to server contentType : varContentType, // content type sent to server dataType : varDataType, //Expected data format from server processdata : varProcessData, //True or False success : function(msg) {//On Successfull service call ServiceSucceeded(msg); }, error: ServiceFailed// When Service call fails }); } </code></pre> <p>The bit im confused about is the sucess object. The jQuery documentation says:</p> <pre><code>success(data, textStatus, jqXHR)Function, Array A function to be called if the request succeeds. The function gets passed three arguments: The data returned from the server, formatted according to the dataType parameter; a string describing the status; and the jqXHR (in jQuery 1.4.x, XMLHttpRequest) object. As of jQuery 1.5, the success setting can accept an array of functions. Each function will be called in turn. This is an Ajax Event. </code></pre> <p>But this method signature looks nothing like the:</p> <pre><code>success : function(msg) {//On Successfull service call ServiceSucceeded(msg); } </code></pre> <p>Object that we seem to be passing in.</p> <p>Questions:</p> <p>1) What does <code>function(msg){ServiceSucceeded(msg)}</code> mean?</p> <p>2) What is 'msg' in this context?</p> <p>3) How on earth am I meant to know how to structure the method sugnature for sucess?</p>
