[英]How to access window object from XUL?
I'm trying to set an onLoad
event to the current web page from a firefox extension. 我正在尝试从firefox扩展
onLoad
事件设置为当前网页。 I'm using the gBrowser
object but I'm not sure if this is the best way. 我正在使用
gBrowser
对象,但不确定是否这是最好的方法。 I would like to set an onLoad
event to the web page window to execute some actions of the plugin as soon as the page is loaded. 我想在网页窗口上设置一个
onLoad
事件,以在页面加载后立即执行插件的某些操作。
Thanks in advance. 提前致谢。
After several attempts I found a solution for this. 经过几次尝试,我找到了解决方案。 Lets say we have a
function
called pageLoaded
, which is the one we want to call when the website has been totally loaded. 可以说我们有一个名为
pageLoaded
的function
,当网站完全加载后,我们要调用该function
。 Now, we have to add an event listener to the gBrowser
object to catch the load
event. 现在,我们必须向
gBrowser
对象添加一个事件侦听器以捕获load
事件。
Here the code: 这里的代码:
function pageLoaded(){
alert("the page has been loaded")
}
gBrowser.addEventListener("load", pageLoaded, true);
I recommend to use add an event listener to the extension document before to add it to the gBrowser. 我建议先使用事件监听器添加到扩展文档中,然后再将其添加到gBrowser中。 The result would be something like this:
结果将是这样的:
window.addEventListener("load", function () {
gBrowser.addEventListener("load", pageLoaded, true);
}, false);
I hope this solution will be useful for someone. 我希望此解决方案对某人有用。
Thanks for reading. 谢谢阅读。
