###DOM元素的创建和添加

• 父类.appendChild(子节点)

• 父类.insertBefore(子节点，在谁之前)

  <ul id = "ul1"></ul>
  
  var a =function(){
      var oLi=document.createElement('li');
      var aLi=oUl.getElementsByTagName('li');
  
      oLi.innerHTML=oTxt.value;
      if(aLi.length>0){//判断使为了适配IE浏览器
          oUl.insertBefore(oLi,aLi[0]);
          //ali[0],是为了插到第一位
      }else{
          oUl.appendChild(oLi);
      }
  
  };
  

###删除元素

• 父级.removeChild(子节点)

  <ul id = "ul1">
  <li>1<a herf="#">删除</a></li>
  <li>2<a herf="#">删除</a></li>
  <li>3<a herf="#">删除</a></li>
  <li>4<a herf="#">删除</a></li>
  </ul>
  
  var a =function(){
      var aA=document.getElementsByTagName('a');
      var oUl=document.getElementbYId('ul1');
      for(var i=0;i<aA.length;i++){
          aA[i].onclick=function(){
              oul.removeChild(this.parentNode);
  
      };
  
  };
  

###控制表单元素

• rows 列
• cells 行

var oTab=document.getElementById('tab1');
alert(oTab.tBodies[0].rows[1].cells[1].innerHTML);//输出列表中tbody中的第二列中的第二行的文本

I strongly recommend against using any <blink> tags.

you’ve got to put paragraph tags in your blockquotes:
