如何使用JSLint全局设置'use strict' [英] How to set 'use strict' globally with JSLint

问题描述

我是javascript的新手，正在尝试通过JSLint进行验证。
我应该在哪里放使用严格来全局使用并验证？

I'm new to javascript and am trying to validate through JSLint. Where should I put "use strict" to use it globally and validate?

这给了我错误在语句位置使用严格'的意外表达式。：

This gives me error "Unexpected expression 'use strict' in statement position.":

    "use strict";
    console.log('doing js in head-section');

    function helloWorld() {
        console.log('called function helloWorld()');
        alert('Hello World from a JS function showing an alert!');
    }

    function helloMyNumber() {
        console.log('called function helloMyNumber()');
        var max = 42;
        var yourLuckyNumber = prompt('Enter your lucky number (between 1 and '+ max +')');
        var myLuckyNumber = Math.floor(Math.random()*(max+1));
        var paragraph = document.getElementById('luckynumber');
        paragraph.innerHTML = paragraph.innerHTML + ' Your lucky number is: ' + yourLuckyNumber + '. Mine is: ' + myLuckyNumber + '. They ' + (yourLuckyNumber == myLuckyNumber ? 'DID ' : 'did NOT ') + 'match!';
    }



    console.log('doing JS in body-section');
    document.writeln('<p class="green">Hello World from JS within a body-section in HTML!</p>');

推荐答案

根据文档，JSLint的浏览器选项会自动禁用在全球范围内使用严格的; 。据我所知，没有办法重新打开它。

According to the documentation, the browser option for JSLint automatically disables use of "use strict"; at the global level. As far as I'm aware, there's no way to turn it back on.

您可以关闭浏览器选项，并获得与<$相同的预先声明的全局变量c $ c>浏览器选项使用：

You could turn off the browser option, and get the same predeclared globals as the browser option by using:

/*global
Audio, clearInterval, clearTimeout, document, event, history, Image, location, name, navigator, Option, screen, setInterval, setTimeout, XMLHttpRequest
*/

或者，您可以将所有代码包装在IIFE中，并在其顶部使用use strict; 。

Alternately you could wrap all of your code in an IIFE and use "use strict"; at the top of it.

或者，您可以切换到 JSHint （有更多选项），以及使用 strict：global 选项在全局范围内允许use strict; 。

Alternately you could switch to JSHint (has more options), and use its strict: global option to allow "use strict"; at global scope.
