1.创建链接

<BODY>
<script language="JavaScript">
var o = document.body;
//创建链接
function createA(url,text)
{
    var a = document.createElement("a");
    a.href = url;
    a.innerHTML = text;
    a.style.color = "red";
    o.appendChild(a);
}
createA("http://www.hao123.com/","hao");
</script>
</BODY>



     2.创建DIV

<body>
<script language="javascript">
var o = document.body;
//创建DIV
function createDIV(text)
{
    var div = document.createElement("div");
    div.innerHTML = text;
    div.style.background = "red";
    o.appendChild(div);
}
createDIV("div");
</script>
</body>



           3.创建表单项

<BODY>
<script language="javascript">
var o = document.body;
//创建表单项
function createInput(sType,sValue)
{
    var input = document.createElement("input");
    input.type = sType;
    input.value = sValue;
    o.appendChild(input);
}
createInput("button","aa");
</script>
</BODY>

               4.创建表格

<BODY>
<script language="javascript">
var o = document.body;
//创建表格
function createTable(w,h,r,c)
{
    var table = document.createElement("table");
    var tbody = document.createElement("tbody");
    table.width = w;
    table.height = h;
    table.border = 1;
    for(var i=1;i<=r;i++)
    {
        var tr = document.createElement("tr");
        for(var j=1;j<=c;j++)
        {
            var td = document.createElement("td");
            td.innerHTML = i + "" + j;
            //td.appendChild(document.createTextNode(i + "" + j));
            td.style.color = "#FF0000";
            tr.appendChild(td);
        }
        tbody.appendChild(tr);
    }
    table.appendChild(tbody);
    o.appendChild(table);
}
createTable(270,270,9,9);
</script>
</BODY>

     4.创建按钮,文本框并窗体传值(HTMLPage1.htm)

   <script type="text/javascript">


        var index = 2;

        function addEle() {

            var txt = document.createElement("input");
            txt.setAttribute("type", "input");
            txt.setAttribute("id", "txt" + index);

            var btn = document.createElement("input");
            btn.setAttribute("type", "`");
            btn.setAttribute("id", "btn" + index);
            btn.setAttribute("value", "取值");
            btn.setAttribute("onclick", "openWindow()");

            var br = document.createElement("br");

            document.getElementById("content").appendChild(txt);
            document.getElementById("content").appendChild(btn);
            document.getElementById("content").appendChild(br);

            index++;

        }

        function openWindow() {
            var returnVal = window.showModalDialog("HTMLPage2.htm", "", "");
            var srcID = window.event.srcElement.id;//触发事件的对象.
            var ind = srcID.substr(3,srcID.length);
            for (var i in returnVal) {
                document.getElementById("txt" + ind).value += returnVal[i]+" ";
            }
        }

    </script>

                       HTMLPage2.htm

   <script type="text/javascript">

        function sub() {
            var arr = document.getElementsByTagName("input");
            var val = new Array();
            for (var i in arr) {
                if (arr[i].type == "checkbox") {
                    if (arr[i].checked) {
                        val[val.length] = arr[i].value;
                    }
                }
            }
            window.returnValue = val;
            window.close();
        }

    </script>
