下面小編就為大家?guī)硪黄狫S實現(xiàn)動態(tài)增加和刪除li標簽行的實例代碼。小編覺得挺不錯的，現(xiàn)在就分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

如下所示：

function addDepartment()
{
<span style="white-space:pre">	</span>var x = document.getElementById('department');
<span style="white-space:pre">	</span>var l = x.childNodes.length;
<span style="white-space:pre">	</span>var li = document.createElement("li");
<span style="white-space:pre">	</span>li.className = "list_nr_bg";
<span style="white-space:pre">	</span>li.innerHTML = "<span class='nr6'><select name='institute'><c:if test='${baseInstitutes !=null}'><c:forEach items='${baseInstitutes}' var='baseInstitute'><option value='${baseInstitute.id}'>${baseInstitute.instituteName}</option></c:forEach></c:if></select></span><span class='nr6'>專業(yè)：</span><span class='nr6'><input name='specialty' type='text'></span><span><input type='button' onclick='deleteDepartment(this)' value='刪除'></span>";
<span style="white-space:pre">	</span>x.appendChild(li);
}

function deleteDepartment(obj)
{
<span style="white-space:pre">	</span>if(window.confirm("確認刪除嗎？")){
<span style="white-space:pre">		</span>var li = obj.parentNode.parentNode; //獲得當前行
<span style="white-space:pre">		</span>var ul = li.parentNode;//獲得上一級標簽
<span style="white-space:pre">		</span>ul.removeChild(li); //刪除當前行
<span style="white-space:pre">	</span>} else {
<span style="white-space:pre">		</span>return false;
<span style="white-space:pre">	</span>}
}

HTML：

<ul id="department">
<span style="white-space:pre">	</span><li class="list_nr_bg">
<span style="white-space:pre">		</span><span class="nr6">所屬院系：</span>
<span style="white-space:pre">		</span><span><input type="button" onclick="addDepartment()" value="增加"></span>
<span style="white-space:pre">	</span></li>
<span style="white-space:pre">	</span><li class="list_nr_bg">
<span style="white-space:pre">		</span><span class="nr6">
<span style="white-space:pre">		</span><select name="institute">
<span style="white-space:pre">		</span><c:if test="${baseInstitutes !=null}">
<span style="white-space:pre">		</span><c:forEach items="${baseInstitutes}" var="baseInstitute">
<span style="white-space:pre">			</span><option value="${baseInstitute.id}">${baseInstitute.instituteName}</option>
<span style="white-space:pre">		</span></c:forEach>
<span style="white-space:pre">		</span></c:if>
<span style="white-space:pre">		</span>/select>
<span style="white-space:pre">		</span></span>
<span style="white-space:pre">		</span><span class="nr6">專業(yè)：</span>
<span style="white-space:pre">		</span><span class="nr6"><input name="specialty" type="text"></span>
<span style="white-space:pre">	</span></li></ul>
