o.appendChild(div);
}
createDIV("div");

<script language="javascript">
var o = document.body;

createInput("button","aa");
</script>

//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);

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();
}
