Javascript jshint预期出现分配错误

对于上面JSHINT中的代码，我收到以下错误消息：

“应为赋值或函数调用，而应为表达式”

有人能告诉我怎么解决这个问题吗

谢谢大家!

布尔表达式依赖null或undefined的“错误”来决定是分配$this.data还是分配数组文本。我猜jshint希望您明确地指定一个值，以便您可以显式地检查$this.data是否为null或未定义，然后相应地指定。

这是错误的（逗号）

试试这个（分号-；）

说你的JS是完全有效的。这个错误可能是因为这个表达式与它前面的其他代码有关。你能给我们多一点吗？@saurecreative，请看上面：）我的第一个想法是，这可能与你用逗号分隔多个任务有关，但在开始时没有

var

关键字。试着把它们改成分号，看看是否可以。是的，我应该看到的！谢谢！：）
