Question

我是新来的。我想添加一些代码，除了光标点击之外，还允许我使用回车键在通过文本框提交的位置初始化谷歌地图。我有点击部分，输入键，而不是:(

<input id="address" type="text">
<input id="search" type="button" value="search" onClick="search_func()">

<script>
  function search_func() {
    var address = document.getElementById("address").value;
    initialize();
  }
</script>

Answer 2

function search_func(e)
{
    e = e || window.event;
    if (e.keyCode == 13)
    {
        document.getElementById('search').click();
        return false;
    }
    return true;
}

Answer 3

你想要在你的文本框中添加一个监听器，当你输入的键被输入时（13是要输入的keyCode），在keydown上激活search_func：

<input id="address" type="text" onkeydown="key_down()">
<input id="search" type="button" value="search" onClick="search_func()">

<script>
  function key_down(e) {
    if(e.keyCode === 13) {
      search_func();
    }
  }

  function search_func() {
    var address = document.getElementById("address").value;
    initialize();
  }
</script>
