在一种方法中访问变量，该方法在其他方法中使用

Question

我想从doinit访问变量以保存开销方法。我试图在saveExpense中访问临时变量。控制台正在抛出未定义的

 ({
 doInit: function(component, event, helper) {
    helper.getMatrix(component, event);
    helper.getRolesConverted(component, event);
    var temp=0;
},
saveExpenses: function(component, event, helper) {
     helper.saveExpenses(component, event);
     console.log('temp value ',temp);
},
});

Answer 1

var temp;
({
 doInit: function(component, event, helper) {
    helper.getMatrix(component, event);
    helper.getRolesConverted(component, event);
    temp=0;
},
saveExpenses: function(component, event, helper) {
     helper.saveExpenses(component, event);
     console.log('temp value ',temp);
},
});
