javascript - 当用户单击键盘上的 Enter 时触发按钮单击

标签 javascript html css search responsive

我的网站有一个搜索按钮，用户可以在其中输入他们想要搜索的内容，网站会删除所有与搜索内容不匹配的产品，并保留与输入的产品名称匹配的所有产品，然后单击搜索按钮后，页面将转到产品部分，显示匹配的搜索产品。我想让用户还可以选择单击计算机上的“Enter”键和手机上的搜索按钮来触发页面向下滚动到网站中的#products 部分的相同效果。

非常感谢我收到的任何帮助，如果需要更多信息或说明，请告诉我。

<!-- custom js file link  -->
<script src="js/script.js"></script>

</body>
</html>

也可以按 Enter 键进行搜索。

最佳答案 

function Onpress(e){
  let pressedkey=(window.event)?event.charCode:e.which;
  if(pressedkey == 13){
    search_products();
    // your logic
  }
}

并将 onkeypress 事件添加到输入中，例如

Onkeypress="Onpress(event)"
