在< body>内通过javascript为body.onload添加事件处理程序部分 [英] Add event handler for body.onload by javascript within <body> part
问题描述
我们希望在我们的文档中包含来自Google Maps API的地图。这个文档告诉我们用一个由body的onload（）事件调用的函数来初始化map。
We want to include a maps from Google Maps API in our document. The documentation tells to initialize the map with a function called by the onload() event of the body.
调用方式：
<body onload="initialize_map();">
这对我们来说并不奏效，因为我们使用Template :: Toolkit和< body> 标签已经包含在我们的包装中。简而言之：当我们的javascript代码开始运行时，已经打印了< body> 标记。
This doesn't work out for us because we're using Template::Toolkit and the <body> tag is already included in our wrapper. In short: The <body> tag is already printed when our javascript code starts running.
像这样，但它只适用于 onclick ，而不是 onload 。我想这是因为JavaScript代码位于< body> 标签本身之下。
I tried something like this but it does only work for onclick, not onload. I guess that's because the javascript code is beneath the <body> tag itself.
var body = document.getElementsByTagName("body")[0];
body.addEventListener("load", init(), false);
function init() {
alert("it works!");
};
任何帮助如何启动Google Maps地图的人都会感激！
Any help how to fire up a Google Maps map appreciated!
推荐答案
由于我们已经使用jQuery来实现图形视觉特效，因此我们最终使用了这个功能。类似于
As we were already using jQuery for a graphical eye-candy feature we ended up using this. A code like
$(document).ready(function() {
// any code goes here
init();
});
完成了我们想要的任何事情，并关心自己的浏览器不兼容问题。
did everything we wanted and cares about browser incompatibilities at its own.
