什么是“google.maps.event.addDomListener（window，'load'，initialize）;”意思？ [英] what does "google.maps.event.addDomListener(window, 'load', initialize);" mean?

问题描述

这是什么意思？

  google.maps.event.addDomListener（window，'load'，initialize）; 
  

我有函数'initialize（）'，但我还添加了两个参数，经度和纬度，像这样：

$ p $ 函数初始化（经度，纬度）{

}
code>

因为这样，我必须对行中的'initialize'做任何事情：



  google.maps.event.addDomListener（window，'load'，initialize）; 
  




解决方案

google.maps.event.addDomListener 将DOM事件侦听器添加到窗口中对象，用于'load'事件，并指定一个要运行的函数。

来自文档：

addDomListener （实例：Object，eventName：string，handler：function（？），capture？：boolean）MapsEventListener跨浏览器事件处理程序注册。通过为该函数返回的句柄调用removeListener（handle）来移除该监听器。

在 google.maps.event.addDomListener（window，'load'，initialize）中初始化; 是一个函数指针，你不能传递参数接着就，随即。要传入参数，请将其包装在匿名函数（不带参数）中：

  google.maps.event。 addDomListener（window，'load'，function（）{
 initialize（latitude，longitude）; 
}）; 
  

What does this mean?

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:

function initialize(longitude, latitude){

}

because of this do I have to do anything to the 'initialize' in the line:

google.maps.event.addDomListener(window, 'load', initialize);

解决方案

The google.maps.event.addDomListener adds a DOM event listener, in this case to the window object, for the 'load' event, and specifies a function to run.

from the documentation:

addDomListener(instance:Object, eventName:string, handler:function(?), capture?:boolean) MapsEventListener Cross browser event handler registration. This listener is removed by calling removeListener(handle) for the handle that is returned by this function.

The initialize in 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):

google.maps.event.addDomListener(window, 'load', function () {
   initialize(latitude, longitude);
});
