使用鼠标悬停时获取数据

Question

此代码有效，但您需要先选择或单击数据，然后再显示数据。我想要做的是使用鼠标悬停，然后将显示数据，因为输入和显示数据时有类似的数据，所以我认为我应该使用鼠标悬停，这样您就可以看到数据的差异。非常感谢您的帮助

在此处输入图像描述

  <tr class='tr_input'>
        <td><textarea rows="3" type='text' name='sear[]' class='form-control sear' id='sear_1'></textarea></td>

尝试鼠标悬停事件，替换点击。

就像那里：

document.getElementById("some").addEventListener("mouseenter", function( event ) {
    // todo something
}, false);
