javascript - 在 eslint 中启用 space-before-blocks 时，仅强制使用一个空格而不是多个空格

Question

如何正确配置规则以强制在带大括号的代码块之前仅包含一个空格而不是多个空格或制表符？

到目前为止我一直在使用:

/* globals isCorrect, aValue callback */
/*eslint space-before-blocks: "error"*/

if (isCorrect)  { // That should be incorrect, more than one space
    callback('correct');
} else if(aValue == 5) { // That should be correct, only one space
    callback('aValue');
} else      { // That is also incorrect, tabs!
    callback('incorrect');
}

您可以使用no-multi-spaces为了那个原因!将 /* no-multi-spaces: "error"*/ 添加到您的示例中，并在 demo 中尝试它:

/* globals isCorrect, aValue callback */
/* eslint space-before-blocks: "error" */
/* eslint no-multi-spaces: "error" */

if (isCorrect)  { // That should be incorrect, more than one space
    callback('correct');
} else if(aValue == 5) { // That should be correct, only one space
    callback('aValue');
} else      { // That is also incorrect, tabs!
    callback('incorrect');
}

这应该会给你你想要的错误:

5:17 - Multiple spaces found before '{'. (no-multi-spaces)
9:13 - Multiple spaces found before '{'. (no-multi-spaces)
