javascript - 按Enter键执行

我有这个代码

<script>
function cA( url )
{
    document.myform.action = url;
}
</script>

<input type="whatever" name="whatever" id="whatever" />
<button class="whatever-button" id="defaultAction" value="Go for it" name="whatever" type="submit" onClick="cA('whatever.php#anchor')" >Go for it
</button>

当您单击开始按钮时，正在加载whatever.php#anchor。我如何更改输入标签的元素以使其执行与单击按钮相同的cA('whatever.php#anchor')？

因此，当用户在该字段中按下Enter键时，应该加载站点whatever.php#anchor，或更具体地说，应执行cA('whatever.php#anchor')。

该页面上有更多按钮，因此将一个按钮设置为默认按钮不起作用。

PS：

将所有内容包装成一种形式不起作用，因为页面的结构是

<form>
    <script>
    function cA( url )
    {
        document.myform.action = url;
    }
    </script>

    <input type="whatever1" name="whatever1" id="whatever1" />
    <button class="whatever1-button" id="defaultAction1" value="Go for it" name="whatever1" type="submit" onClick="cA('whatever.php#anchor1')" >Go for it
    </button>

    <input type="whatever2" name="whatever2" id="whatever2" />
    <button class="whatever2-button2" id="defaultAction2" value="Go for it" name="whatever2" type="submit" onClick="cA('whatever.php#anchor2')" >Go for it
    </button>

    <input type="whatever3" name="whatever3" id="whatever3" />
    <button class="whatever3-button" id="defaultAction3" value="Go for it" name="whatever3" type="submit" onClick="cA('whatever.php#anchor3')" >Go for it
    </button>
    ...
</form>

最佳答案

您可以尝试以下方法：

<input type="whatever" name="whatever" id="whatever" onkeydown="if (event.keyCode == 13) {cA('whatever.php#anchor');}" />
