Javascript button onclick not creating record

Question

I have a custom java script button on Account object. Clicking the button should create Case (Child of Account) and Issue__c (Child of Case object) records.

Case record is created successfully, but Issue record is not created. Attached the error message screenshot.

Below is the javascript code:

{!REQUIRESCRIPT("/soap/ajax/22.0/connection.js")}
var newcase= new sforce.SObject("Case");

newcase.Status = "New";
newcase.Origin= "Phone";
var result = sforce.connection.create([newcase]);
alert('A case has been created with number:'+result);
var newissue = new sforce.SObject("Issue__c");
newissue.Case__c = newcase.Id;
newissue.Name = "Name 1"
var result1 = sforce.connection.create([newissue]);
alert('A Issue has been created with number:'+result1);
window.location.reload();

You can access the newly created Case id using the result variable.

In fact, the create method returns an array of type SaveResult as you can see here.

This type contains an id variable and a success variable as boolean.

Here's the right code:

{!REQUIRESCRIPT("/soap/ajax/22.0/connection.js")}
var newcase= new sforce.SObject("Case");

newcase.Status = "New";
newcase.Origin= "Phone";
var result = sforce.connection.create([newcase]);
if(result[0].success == 'true'){
   var newissue = new sforce.SObject("Issue__c");
   newissue.Case__c = result[0].id;
   newissue.Name = "Name 1";
   var result1 = sforce.connection.create([newissue]);
   if(result1[0].success == 'true'){
      window.location.reload();
   }else{
      alert('An error occurred during the issue creation');
   }
}else{
   alert('An error occured during the case creation');
}
