此函数有效,但是如何避免为第二个变量键入相同的for循环,而仅使用一个变量。尝试在这里不重复您自己的方法。我需要使用数组吗?
JS:
var app=angular.module('xpCalc', []);
app.controller('xpCalculatorController', function($scope){
$scope.currentLevel=1;
$scope.currentXp=function(){
var output=0;
for (var thisLVL=1; thisLVL < $scope.currentLevel; thisLVL++) {
output += ( Math.floor ( thisLVL + 300 * Math.pow( 2, thisLVL / 7 ) ) / 4 );
}
return output;
};
$scope.desiredLevel=1;
$scope.desiredXp=function(){
var output=0;
for (var thisLVL=1; thisLVL < $scope.desiredLevel; thisLVL++) {
output += ( Math.floor ( thisLVL + 300 * Math.pow( 2, thisLVL / 7 ) ) / 4 );
}
return output;
};
});
HTML:
<h2>{{desiredXp()-currentXp()}}</h2>
最佳答案
试试这个。
var app=angular.module('xpCalc', []);
app.controller('xpCalculatorController', function($scope){
$scope.currentLevel=1;
$scope.currentXp=InternalLoop($scope.currentLevel);
$scope.desiredLevel=1;
$scope.desiredXp=InternalLoop($scope.desiredLevel);
function InternalLoop(level){
var output=0;
for (var thisLVL=1; thisLVL < level; thisLVL++) {
output += ( Math.floor ( thisLVL + 300 * Math.pow( 2, thisLVL / 7 ) ) / 4 );
}
return output;
};
});
