我想知道如何将“ this”传递给外部模块(script.js)。 当前传递给'script.js'的'this'是不确定的,但是我想找到一种传递默认全局对象的方法。顺便说一句,script.js是由另一个库自动生成的,因此我无法进行任何更改。请帮忙。
index.html
<script src='./script.js' defer></script>
<script>
var interval = setInterval(function () {
if (document.readyState === 'complete') {
clearInterval(interval);
(function (scope) {
console.log('this inside of function')
console.log(scope) //this prints 'global {frames: global, ..}
})(this) // <<<<< THIS works
}
}, 100);
</script>
script.js
(function (scope) {
console.log('this inside of script.js')
console.log(scope) /// this prints 'undefined'
})(this) // << THIS is undefined.
