javascript - Using jQuery, how do I pass arg to function and then display a message from predefined variable -

-

i want call function, pass type of error arg, , display message.

function msgdialog(msg) {     // define messages     var errormsg = "there has been error.  sorry that.";     var loginmsg = "something went awry login.  please try again.";     var uploadmsg = "your upload failed.  please try again.";     var networkmsg = "you not connected internet.  please connect , try again.";      alert(msg); }

how call function msgdialog(loginmsg) , have var can assign correct message, that? here alerting it, display differently. know need create new var value of arg value, not sure how. thank you.

that pure javascript, no jquery. try this:

var msgdialog = (function() {     var errors = {         errormsg : "there has been error.  sorry that.",         loginmsg : "something went awry login.  please try again.",         uploadmsg : "your upload failed.  please try again.",         networkmsg : "you not connected internet.  please connect , try again."     }      return function(msg){         alert(errors[msg]);     } })();  msgdialog('uploadmsg'); //  alerts "your upload failed.  please try again."

you can idea of what's going on here if hadn't seen javascript closures before.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
