我在我的网页上加载了三个脚本,我想在其中两个脚本完成加载后触发一个函数.
head.js(
{ webfont: 'http://ajax.googleapis.com/ajax/libs/webfont/1.0.31/webfont.js' },
{ jquery: 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js' },
{ analytics: 'http://www.google-analytics.com/ga.js' }
);

理想情况下,我希望能够执行以下操作,但根据文档(请参阅脚本组织),似乎无法使head.ready()等待加载两个脚本.
head.ready('jquery', function() {
// Code that requires jQuery.
});
// This is not supported. :-(
head.ready('jquery', 'analytics', function() {
// Code that requires both jQuery and Google Analytics.
// ...
});

那我该怎么解决呢?如果我嵌套就绪方法,我可以确定我的代码将被触发,还是只有在jquery在分析之前完成加载时才会触发它?
head.ready('jquery', function() {
// Code that requires jQuery.
// ...
head.ready('analytics', function() {
// Code that requires both jQuery and Google Analytics.
// ...
});
});

另一种解决方案可能是将加载语句分成两部分,如下所示.但是,我仍然可以从异步加载脚本中获益,还是在jquery和分析之前完成加载webfont?
head.js(
{ webfont: 'http://ajax.googleapis.com/ajax/libs/webfont/1.0.31/webfont.js' }
);
head.js(
{ jquery: 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js' },
{ analytics: 'http://www.google-analytics.com/ga.js' },
function() {
// Code that requires both jQuery and Google Analytics.
// ...
}
);
head.ready('jquery', function() {
// Code that requires jQuery.
// ...
});

由于脚本按顺序执行(即使并行加载),您可以等待"最后一行"的脚本
head.js(
{ webfont : 'http://ajax.googleapis.com/ajax/libs/webfont/1.0.31/webfont.js' },
{ jquery : 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js' },
{ analytics: 'http://www.google-analytics.com/ga.js' }
);
head.ready('analytics', function() {
// when this triggers, webfont & jquery will have finished loading too
});
