在严格的javascript中在事件处理程序中使用此代码?

问题描述：

假设您有一个类似于以下的例程来连接Click事件处理程序

Suppose you have a routine like the following to wire up click event handlers

getElements(".board>div").forEach(function(elem){
  elem.addEventListener("click", handleClick);
});

然后在处理程序中，您需要与发件人(即此人)一起工作

And then in the handler, you need to work with the sender (i.e. this)

function handleClick(){      
  if(this.innerText.toLowerCase() !== "x"){ 
    ...

在这种情况下，如何在没有jshint违反/警告的情况下使用this?

How do you use this in this scenario without a jshint violation/warning?

答

您对this的使用有效.要消除事件处理程序中的this错误，请在函数顶部添加/*jshint validthis: true */.

Your use of this is valid. To suppress the this errors in your event handler add /*jshint validthis: true */ to the top of the function.
