Js实现动态添加删除Table行示例

  最近做项目遇到要动态添加、删除表格行的操作,实现如下

  html代码

  

复制代码 代码如下:

  <table cellpadding="0" cellspacing="0" border="1" style="margin:auto; width:96%;" id="LearnInfoItem">

  <tr >

  <td colspan="8" bgcolor="#96E0E2" style="height:30px;" ><h3 style="text-align:center; margin:0;">主要学习简历</h3></td>

  </tr>

  <tr id="tr1">

  <td class="tdStyle2">起讫时间 </td>

  <td class="tdStyle2">毕业院校</td>

  <td class="tdStyle2">所学专业</td>

  <td class="tdStyle2">学制</td>

  <td class="tdStyle2">学位</td>

  <td class="tdStyle2">学习方式</td>

  <td class="tdStyle2">文化程度</td>

  <td class="tdStyle2">

  <input type="button" name="LearnAdd" value="添加" onclick="LearnAddSignRow()" />

  <input name='LearnTRLastIndex' type='hidden' id='LearnTRLastIndex' value="1" />

  </td>

  </tr>

  </table>

  javascript代码:

  

复制代码 代码如下:

  <script language="javascript" type="text/javascript">// Example: obj = findObj("image1");

  function findObj(theObj, theDoc)

  {

  var p, i, foundObj;

  if(!theDoc) theDoc = document;

  if( (p = theObj.indexOf("?")) > 0 && parent.frames.length)

  {

  theDoc = parent.frames[theObj.substring(p+1)].document;

  theObj = theObj.substring(0,p);

  }

  if(!(foundObj = theDoc[theObj]) && theDoc.all)

  foundObj = theDoc.all[theObj];

  for (i=0; !foundObj && i < theDoc.forms.length; i++)

  foundObj = theDoc.forms[i][theObj];

  for(i=0; !foundObj && theDoc.layers && i < theDoc.layers.length; i++)

  foundObj = findObj(theObj,theDoc.layers[i].document);

  if(!foundObj && document.getElementById)

  foundObj = document.getElementById(theObj);

  return foundObj;

  }

  //添加一行学习简历

  function LearnAddSignRow(){ //读取最后一行的行号,存放在LearnTRLastIndex文本框中

  var LearnTRLastIndex = findObj("LearnTRLastIndex",document);

  var rowID = parseInt(LearnTRLastIndex.value);

  var signFrame = findObj("LearnInfoItem",document);

  //添加行

  var newTR = signFrame.insertRow(signFrame.rows.length);

  newTR.id = "LearnItem" + rowID;

  //添加列:起讫时间

  var newNameTD=newTR.insertCell(0);

  //添加列内容

  newNameTD.innerHTML = "<input name='txtLearnStartDate" + rowID + "' id='txtLearnStartDate" + rowID + "' type='text' class='inputStyle' />";

  //添加列:毕业院校

  var newNameTD=newTR.insertCell(1);

  //添加列内容

  newNameTD.innerHTML = "<input name='txtName" + rowID + "' id='txtName" + rowID + "' type='text' class='inputStyle' />";

  //添加列:所学专业

  var newEmailTD=newTR.insertCell(2);

  //添加列内容

  newEmailTD.innerHTML = "<input name='txtEMail" + rowID + "' id='txtEmail" + rowID + "' type='text' class='inputStyle' />";

  //添加列:学制

  var newTelTD=newTR.insertCell(3);

  //添加列内容

  newTelTD.innerHTML = "<input name='txtTel" + rowID + "' id='txtTel" + rowID + "' type='text' class='inputStyle' />";

  //添加列:学位

  var newMobileTD=newTR.insertCell(4);

  //添加列内容

  newMobileTD.innerHTML = "<input name='txtMobile" + rowID + "' id='txtMobile" + rowID + "' type='text' class='inputStyle' />";

  //添加列:学习方式

  var newMobileTD=newTR.insertCell(5);

  //添加列内容

  newMobileTD.innerHTML = "<input name='txtMobile" + rowID + "' id='txtMobile" + rowID + "' type='text' class='inputStyle' />";

  //添加列:文化程度

  var newCompanyTD=newTR.insertCell(6);

  //添加列内容

  newCompanyTD.innerHTML = "<input name='txtCompany" + rowID + "' id='txtCompany" + rowID + "' type='text' class='inputStyle' />";

  //添加列:删除按钮

  var newDeleteTD=newTR.insertCell(7);

  //添加列内容

  newDeleteTD.innerHTML = "<div align='center'><input id='txtDel" + rowID + "' type='button' value='删除' onclick=\"LearnDeleteRow('LearnItem" + rowID + "')\" class='inputStyle' /></div>";

  //将行号推进下一行

  LearnTRLastIndex.value = (rowID + 1).toString() ;

  }

  //删除指定行

  function LearnDeleteRow(rowid){

  var signFrame = findObj("LearnInfoItem",document);

  var signItem = findObj(rowid,document);

  //获取将要删除的行的Index

  var rowIndex = signItem.rowIndex;

  //删除指定Index的行

  signFrame.deleteRow(rowIndex);

  }

  }

  </script>

  实现效果:
