我想知道如何将参数传递给模块
例如,我想在调用模块时为计数器传递一个值,类似于
testModule.resetCounter(20);
(来自http://www.addyosmani.com/resources/essentialjsdesignpatterns/book/#modulepatternjavascript的代码示例)
var testModule = (function () {
var counter = 0;
return {
incrementCounter: function () {
return counter++;
},
resetCounter: function () {
console.log( "counter value prior to reset: " + counter );
counter = 0;
}
};
})();
// Usage:
// Increment our counter
testModule.incrementCounter();
// Check the counter value and reset
// Outputs: 1
testModule.resetCounter();

只需在resetCounter
函数中添加一个参数:
resetCounter: function(count) { ... }

试试这个:
resetCounter: function (v) {
console.log( "counter value prior to reset: " + counter );
counter = (v && (typeof v === "number"))? v: 0;
console.log( "counter value after reset: " + counter );
}
