what does "google.maps.event.addDomListener(window, 'load', initialize);" mean?
提问by Feath
What does this mean?
这是什么意思？
google.maps.event.addDomListener(window, 'load', initialize);
I have the function 'initialize()' but I also added two paramters, longitude and latitude so it's like this:
我有函数 'initialize()' 但我还添加了两个参数，经度和纬度，所以它是这样的：
function initialize(longitude, latitude){
}
because of this do I have to do anything to the 'initialize' in the line:
因此，我必须对行中的“初始化”做任何事情：
google.maps.event.addDomListener(window, 'load', initialize);

The google.maps.event.addDomListeneradds a DOM event listener, in this case to the windowobject, for the 'load' event, and specifies a function to run.
所述google.maps.event.addDomListener增加了DOM事件侦听器，在这种情况下到window对象，为“负载”事件，并指定要运行的功能。
from the documentation:
从文档：
addDomListener(instance:Object, eventName:string, handler:function(?), capture?:boolean)
Return Value:MapsEventListener
Cross browser event handler registration. This listener is removed by calling removeListener(handle) for the handle that is returned by this function.
addDomListener(instance:Object, eventName:string, handler:function(?), capture?:boolean)
返回值：MapsEventListener
跨浏览器事件处理程序注册。通过为此函数返回的句柄调用 removeListener(handle) 来删除此侦听器。
The initializein google.maps.event.addDomListener(window, 'load', initialize);is a function pointer, you can't pass arguments with that. To pass in arguments, wrap it in an anonymous function (that doesn't take arguments):
该initialize中google.maps.event.addDomListener(window, 'load', initialize);是一个函数指针，你不能传递与参数。要传入参数，请将其包装在一个匿名函数中（不带参数）：
google.maps.event.addDomListener(window, 'load', function () {
initialize(latitude, longitude);
});

It looks like it calls initializewhen the DOM is loaded, but probably without the parameters, if I interpret the docscorrectly.
它看起来像是initialize在加载 DOM 时调用，但如果我正确解释文档，则可能没有参数。
But you could wrap the call inside another function and pass that to the method. It can be an anonymous function, like so:
但是您可以将调用包装在另一个函数中并将其传递给该方法。它可以是一个匿名函数，如下所示：
google.maps.event.addDomListener(window, 'load', function(){
initialize(50.0000, 60.0000);
});
