如何在按下回车键时，获取文本框的值？

coding2live 2021-02-05 16:09:17 0 127 javascript, html, input, keycode 

<input type="text" placeholder="some text" class="search" onkeydown="search()"/>
<input type="text" placeholder="some text" class="search" onkeydown="search()"/>

我想用js监听用户是否按下了回车键：

function search() {
    if(event.keyCode == 13) {
        alert("should get the innerHTML or text value here");
    }
}

现在这段代码运行起来没问题。

但我的问题是如何获取input里面的值，我的想法是给函数传递一个引用 “this”；

或者如果他们有id，那么我可以使用id，但我不知道如何区分哪个input是当前被输入的…
