[英]How do I create a Javascript package with a constructor in it?
Here I attempted to create a package called com.matogen.ght with a class in it, Calendar. 在这里,我尝试创建一个名为com.matogen.ght的包,其中包含一个类Calendar。 I'd like the init() method to be called automatically when I instantiate the calendar object.
我想在实例化日历对象时自动调用init()方法。 The example below works, but I still have to explicitly call the init() method.
下面的示例有效,但我仍然必须显式调用init()方法。
var com = {
matogen : {
ght : {
'Calendar' : function() {
this.init = function() {
console.log("This is my constructor");
}
}
}
}
}
$(document).ready(function() {
var cal = new com.matogen.ght.Calendar();
cal.init();
});
just change your init
function like so 只需更改你的
init
函数
this.init = (function() {
console.log("This is my constructor");
}());
with a self executed anonymous function or, if you prefer, just call the function itself like so 使用自执行匿名函数,或者,如果您愿意,只需像这样调用函数本身
...
Calendar : function() {
this.init = function() {
console.log("This is my constructor");
};
this.init();
}
...
Well, as you are doing new
com.matogen.ght.Calendar()
, Calendar()
is your constructor. 好吧,当你正在做
new
com.matogen.ght.Calendar()
, Calendar()
是你的构造函数。
So: 所以:
var com = {
matogen : {
ght : {
Calendar : function() {
console.log("This is my constructor");
}
}
}
}
... would be accurate. ......会准确的。
