tslint one line rule misplaced 'else'
提问by sreginogemoh
I have such configin tslint.jsonfor one line rule
我有这样config的tslint.json对one line rule
one-line": [true,
"check-open-brace",
"check-catch",
"check-else",
"check-whitespace"
],
When I have code lines like that:
当我有这样的代码行时：
if(SomethingTrue) { next("a"); }
else { next("b"); }
I've got warning:
我有警告：
(one-line) file.ts[17, 9]: misplaced 'else'
Why that is happens?
Is it bad practice to have one line else?
为什么会这样？拥有一个是不好的做法line else吗？

You have :
你有 ：
else { next("b"); }
Else must be one one line. So:
否则必须一一对应。所以：
else {
next("b");
}
Is it bad practice to have one line else?
拥有一条其他线路是不好的做法吗？
Just easier to read. Its a styleguide for consistency.
只是更容易阅读。它是一致性的风格指南。

if (condition is true) {
// do something;
}
else {
// do something else;
}
Notice that elsecomes next to }
注意else旁边的}
if (condition is true) {
// do something;
} else {
// do something else;
}

According to the tslint docsthe problem is that when "check-else"is specified under one-linethe else must be on the same line as the closing brace for your if.
根据tslint 文档，问题是在 else"check-else"下指定的when必须与if 的右one-line大括号在同一行。
So in your case instead of:
所以在你的情况下，而不是：
if(SomethingTrue) { next("a"); }
else { next("b"); }
Use this format:
使用这种格式：
if(SomethingTrue) { next("a"); } else { next("b"); }
回答by SReddy
if (condition) {
// Your Code
} else {
// Your Code
}
End of Ifand start of elseshould be on the same line.
End ofIf和 start ofelse应该在同一行。
