为什么我不能将var放在encodeURI中？

Question

这为什么起作用？

var movieName = encodeURI("deadpool");
var url = "https://api.themoviedb.org/3/search/movie?api_key=" + apiKey + "&query=" + movieName;

这不是吗？我什至放了一个控制台日志进行检查，

var movieName = $(".shown .title").html();
console.log(movieName);

var url = "https://api.themoviedb.org/3/search/movie?api_key=" + apiKey + "&query=" + encodeURI(movieName);

Answer 1

HTML的标题周围可能有空白，您需要将其删除。

var movieName = $(".shown .title").html().trim();

此外，如果有嵌入的HTML标签，您可能应该使用.text()而不是.html()。

var apiKey = "key";

var movieName = encodeURIComponent("deadpool");
var url = "https://api.themoviedb.org/3/search/movie?api_key=" + apiKey + "&query=" + movieName;
console.log(url);

var movieName = $(".shown .title").html().trim();
console.log(movieName);

var url = "https://api.themoviedb.org/3/search/movie?api_key=" + apiKey + "&query=" + encodeURIComponent(movieName);
console.log(url);
