Disable JSHint warning: Expected an assignment or function call and instead saw an expression
提问by Naor
I have the following line:
我有以下几行：
imageUrl && (data.imageUrl = imageUrl);
For this line, JSHint complains:
对于这一行，JSHint 抱怨：
Expected an assignment or function call and instead saw an expression.
I understand the warning, but I want to disable it. I can't find the way how to do it. Any idea?
我理解警告，但我想禁用它。我找不到如何去做的方法。任何的想法？

If it really is just that one line
如果真的只有那一行
imageUrl && (data.imageUrl = imageUrl); // jshint ignore:line
I am a fan of writing code so it doesn't produce warnings, though, even if this means taking special action to do so. So I'd prefer
我是编写代码的粉丝，因此它不会产生警告，即使这意味着要采取特殊措施来这样做。所以我更愿意
if (imageUrl) data.imageUrl = imageUrl;

Include a /* jshint expr: true */comment in your Javascript.
/* jshint expr: true */在您的 Javascript 中包含注释。
