javascript - 如何直接从api获取json并使用它？

Question

var moviereviewtext = "{"title": "Friday the 13th", "year": 1980, "reviews": [{"reviewer": "Pam", "stars": 3, "text": "Pretty good, but could have used more Jason"}, {"reviewer": "Alice", "stars": 4, "text": "The end was good, but a little unsettling"}]}";

var jsonobj = eval("(" + moviereviewtext + ")");

上图中有一个变量，我们以 json 格式输入数据。但我需要的是，我有 api 的 url，我必须从那里获取 json 并将其分配给变量。怎么做？

你没有忘记转义你的引言吗？

如果是这样，你应该这样做:

var moviereviewtext = "{\"title\": \"Friday the 13th\", ...}";

或者那个

var moviereviewtext = "{'title': 'Friday the 13th',  ...}";
