FB.XFBML.parse（）在渲染过程中失败

Question

我一直在尝试执行Port open http://0.0.0.0:9091/ Recived: t Waiting0 Serial < 1100D00H00M00S Recived: t Waiting0 Serial < 1100D00H00M00S Recived: t Waiting0 Serial < 1100D00H00M00S Recived: t Waiting0 Serial < 1100D00H00M00S Recived: t Waiting0 Serial < 1100D00H00M00S Recived: t 来重新加载所有Facebook社交插件。我可以在FB.XFBML.parse();中成功执行，但不能在Template.sample.events({})或Template.sample.onRendered()中执行，因为我收到的错误是Template.sample.rendered未定义。我的代码如下：

FB

OR

Template.sample.onRendered(function() {
  FB.XFBML.parse();
});

如何执行FB.XFBML.parse（）;每次加载模板？

Answer 1

使用try-catch块包装方法。注意到rendered被多次调用。第一次传递失败，表示FB未定义，而后续传递成功。

Template.sample.rendered = function() {
    try {
        FB.XFBML.parse();
    } catch (e) {
        // Will normally crash but succeeding execution will be successful
    }
}
