javascript - 我可以在函数级别设置 jshint 选项吗？

Question

我正在使用 jshint 来监控我的代码质量，但我想对代码的不同部分应用不同的规则/选项。

特别是，有一个函数我有意且必须使用按位运算符。对于这个函数，我想设置 /*jshint bitwise:false */。不过，对于我的其余代码，我想设置 /*jshint bitwise:true */。有没有办法做到这一点，而不是将该功能拆分到另一个脚本文件中？我想象它看起来像这样，但看起来这实际上不起作用。

/*jshint bitwise:true */  //not really needed since it's default

function whatever () {
    // lots of code here
}

function uses_bitwise () {
    /*jshint bitwise:false */
    //bitwise code here
}

是的，您在问题中的语法是正确的。来自 The JSHint documentation :

In addition to the --config flag and .jshintrc file you can configure JSHint from within your files using special comments. These comments start either with jshint or global and are followed by a comma-separated list of value. For example, the following snippet will enable warnings about undefined and unused variables and tell JSHint about a global variable named MY_GLOBAL.

/* jshint undef: true, unused: true */
/* global MY_GLOBAL */

You can use both multi- and single-line comments to configure JSHint. These comments are function scoped meaning that if you put them inside a function they will affect only this function’s code.
