如何从此表单中通过 id 获取元素并将其删除?
<form class="mainForm" name="eform" id="eform" action="#" method="post">
<input type="submit" id="savebutton" value="Save" class="greenBtn" />
<input type="button" id="deletebutton" value="Delete" class="redBtn" />
<input type="button" id="dupbutton" value="Duplicate" class="blueBtn" />
<input type="reset" id="resetbutton" value="Reset" class="greyishBtn" />
</form>
