不用link.click()获取返回的值

在JavaScript中,如果你想要获取点击链接(`a`元素)后的默认行为,比如跳转到新的URL并希望得到返回的结果,通常不需要直接使用`.click()`方法。由于`click()`会触发页面的导航,这意味着实际上你无法直接获取到它的返回值,因为HTTP请求通常是异步的,并不会阻塞浏览器进程。
如果你的目标是获取某个URL的数据,通常你会选择其他方法,比如:
1. 使用`fetch`、`axios`或者`jQuery.ajax`等库发送GET请求:
```javascript
const link = document.querySelector('a');
link.addEventListener('click', function(e) {
e.preventDefault(); // 阻止默认的链接跳转
fetch(link.href)
.then(response => response.json())
.then(data => console.log(data)); // 打印响应的数据
});
```
2. 或者使用`XMLHttpRequest`:
```javascript
const xhr = new XMLHttpRequest();
xhr.open('GET', link.href);
xhr.onload = function() {
if (xhr.status === 200) {
const data = JSON.parse(xhr.responseText); // 解析数据
console.log(data);
}
};
xhr.send();
```
