2015-05-15 19:04:04 -0500	asked a question	How can i reach the array out of document ready function? I've got an array created out of the document ready function, and i need to reach it inside the document ready scopes. `var outarray= []; var i =0; var cmdSonarTopic0 = new ROSLIB.Topic({ ros : ros, name : '/gazebo/sensor/Sonar0', messageType : 'sensor_msgs/Range' }); cmdSonarTopic0.subscribe(function(message) { outarray.push(message.range); console.log(outarray[i]); document.getElementById("abc").innerHTML = outarray[1]; i++; }); $(document).ready(function(){ $("#xyz").text(outarray[1]); var inarray= []; inarray = outarray; ... }); <div> <p id="abc"></p> <p id="xyz"></p> </div>` when i fill the array out of the subscribe function it works, but i need to fill it by datas come from the topic, so it must be in subscribe function. when i do `document.getElementById("abc").innerHTML = outarray[1];` this in the subscribe function, it works ok. But i need to assign the whole array to another array, so need to receive the array from document ready function. when i try the following, it comes empty and writes nothing in tag. `$(document).ready(function(){ $("#xyz").text(outarray[1]); });` So how can i reach the array ?
