判断JS文件是否加载完成再执行操作
记一个JavaScript代码片段。有时需要判断用户是否加载完特定JS文件，然后再相应地触发事件。代码支持现代浏览器运行，不兼容IE7及以下。如果要兼容，可以透过readyState返回状态判断，具体见下文。
function checkJsLoading(url) {
var carHead = document.getElementsByTagName('head')[0];
var carJs = document.createElement('script');
carJs.setAttribute('type', 'text/javascript');
carJs.setAttribute('src', url);
carHead.appendChild(carJs);
carJs.onload = function() {
...
}
}
checkJsLoading('font-awesome.js');
添加IE旧版本兼容支持。
carJs.onreadystatechange = function() {
if (carJs.readyState == 'loaded' || carJs.readyState == 'complete') {
...
}
}
