在下面的CommonJS / Browserify模块中,如何避免每次导入foo和bar？而不是仅仅根据init()中的条件导入所需要的那个？
var Foo = require('foo'),Bar = require('bar'),Component = function(config) {
this.type = config.type;
this.init();
};
Component.prototype = {
init: function() {
var instance = null;
switch (this.type) {
case ('foo'):
instance = new Foo(...);
break;
case ('bar'):
instance = new Bar(...);
break;
}
}
};
解决方法
Component = function(config) {
this.type = config.type;
this.init();
};
Component.prototype = {
init: function() {
var instance = null;
switch (this.type) {
case ('foo'):
instance = new (require('foo'))(...);
break;
case ('bar'):
instance = new (require('bar'))(...);
break;
}
}
};
