JavaScript 实现每次循环都等待

await new Promise(resolve => setTimeout(resolve, 2000));

实现每次循环都等待2秒

async function nextPage() {
  while (true) {
    chocie();
    let next_li = document.querySelector('li[ng-if="directionLinks"][class="ng-scope"]:last-child');
    if (next_li == null){
      break;
    }
    let next_page = next_li.querySelector("a")
    next_page.click();
    await new Promise(resolve => setTimeout(resolve, 2000));
  }
}
 
function chocie(){
    console.log("执行具体的操作")
}
 
nextPage();
