本文介绍了JSLint“超出范围”功能排序导致的错误?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
JSLint似乎对功能排序很挑剔。
JSLint seems to be picky about function ordering.
这好转:
function a() {
'use strict';
return 1;
}
function b() {
'use strict';
a();
}
虽然这给出了'a'不在范围
错误消息:
While this gives an 'a' is out of scope
error message:
function b() {
'use strict';
a();
}
function a() {
'use strict';
return 1;
}
这是设计的吗?我应该关心吗?如何避免在较大(较复杂)的情况下避免给函数一个明确的顺序?
Is this by design? Should I care? How can it be avoided in larger (more complex) cases, where it might not always be possible to give the functions a clear order?
推荐答案
JSLint / JSHint希望您在引用它们之前定义函数。但是,JavaScript并不关心,因为。
JSLint/JSHint expect you to define functions before you reference them. However, JavaScript doesn't care because functions and variables are hoisted.
您可以使用
/* jshint latedef:nofunc */
function b() {
'use strict';
a();
}
function a() {
'use strict';
return 1;
}
