AngularJS：有没有在绑定错别字调试模式？ [英] AngularJS: is there a debug mode for typos in bindings?

问题描述

我刚刚浪费了一个小时的狩猎什么竟然一半是...

I've just wasted half an hour hunting for what turned out to be...

<select.... data-ng-options="x as x.name for x in customerController_clipped.options"

而不是

<select.... data-ng-options="x as x.name for x in customerController_Clipped.options"

即，一个字符的错字 - 在这种情况下，一个剪辑...代替剪辑...'
当然，这是很容易看到它时，它上面的孤立 - 但想想这里面巨大的HTML内容，而你现在知道我为什么问：

That is, a one-character typo - in this case, a 'clip...' instead 'Clip...' Sure, it's easy to see it when it's isolated above - but think of this inside huge HTML content, and you now know why I ask:

有没有办法问AngularJS中绑定的名称报告任何故障，以减轻我们的调试？这种失败的一个简单的控制台日志就足够了，而不是留下我们的组件的静音运行，空...

Is there a way to ask AngularJS to report any failures in names of bindings, to ease our debugging? A simple console logging of this kind of failure would suffice, instead of a silent operation that leaves our components empty...

推荐答案

我看不到建在做这样的东西，虽然也许你可以用angular.js筹集功能请求，或尝试写一拉请求投入 $ parseProvider 的选项？如果你想这样做，我可以看到，现在是通过改变在 $解析服务，做任何的相互preting的code的唯一途径前pressions。

I can't see anything built in for doing this, though maybe you could raise with angular.js as a feature request, or try writing a pull request for putting an option in $parseProvider? If you want to do this the only way I can see right now is by altering the code in the $parse service which does the interpreting of any expressions.

我毫不犹豫地掏出快速测试，看看它是多么容易。原来的code是角1.1.5。搜索ANDYMOD在角1.1.5.js文件中看到的code我已经编辑。这基本上将的console.log 每当在是和以Z AXYZ前pression的部分是不确定的或为空，而不是忽略它。

I've plunked a quick test to see how easy it is. The original code is from angular 1.1.5. Search for ANDYMOD in the angular-1.1.5.js file to see the code I've edited. This basically adds a console.log for whenever the y and z parts of a 'x.y.z' expression are undefined or null, rather than ignoring it.

这绝不是一个值得生产的解决方案，并且不工作，它要使用 NG-CSP ，但它表明的东西至少可以做到。也许你可以在子如果你需要再次测试的这几行...

This is in no way a production-worthy solution, and doesn't work it you want to use ng-csp, but it shows something can be done at least. Maybe you can sub these few lines in if you ever need to test again...
