I am trying to create a simple html page some dynamic buttons. This is what I did so far:
<HTML>
<BODY bgColor="#d4d4d4" onload="OnLoad()" >
<script language = "javascript">
function OnQuery()
{
alert("Query");
}
function OnLoad()
{
document.write("<INPUT onclick=\"OnQuery()\" type=\"button\" value=\" Search \" name=\"querybtn\" />");
}
</script>
</BODY>
</HTML>
As you can guess from code I am very very new to JavaScript. The button 'Search' is getting added but when clicked OnQuery is not called. What am I doing wrong? This is a simple prototype code which is intended only for IE.

- did you tried any xslt ? transforming xml – kbvishnu Commented Aug 17, 2013 at 10:10
- no..I just don't want to generate table. After table I want some buttons which when prssed by user perform some action. So I guess xslt won't help there. – Asha Commented Aug 17, 2013 at 10:12
- 1 You spelled "language" wrong in the script tag. – Ringo Commented Aug 17, 2013 at 10:14
- I correctd it.. still no difference. – Asha Commented Aug 17, 2013 at 10:20
- @Asha you are using incorrect attributes in the input .. check answer below – woofmeow Commented Aug 17, 2013 at 10:29

Reset to default 4Changed the document.writes to using document.createElement to do the Dom creation
function OnQuery()
{
alert("Query");
}
function OnLoad()
{
var Objs = new Array();
var xmlInput = "<QueryResult>Some values</QueryResult>";
var doc = xmldso.XMLDocument;
doc.loadXML(xmlInput );
var x = doc.getElementsByTagName("QueryResult");
for(i=0; i < x.length; ++i)
{
Objs[i] = new MyObject(x[i]);
}
//Create the table element
var table = document.createElement("table");
table.setAttribute("border",1);
for(i=0; i < Exams.length;++i)
{
//Create the row element
var row = document.createElement("tr");
//Create the 2 columns
var col1 = document.createElement("td");
var col2 = document.createElement("td");
//Create the checkbox input
var chkId = "Row" + i;
var chkIdInput = document.createElement("input");
chkIdInput.setAttribute("type","checkbox");
chkIdInput.id = chkId;
//Add the checkbox to the column
col1.appendChild(chkIdInput);
//Set the text of second column
col2.textContent = Objs[i].Prop1;
//Add columns to the row
row.appendChild(col1);
row.appendChild(col2);
//Add the row to the table
table.appendChild(row);
}
//Add the table to the body
document.body.appendChild(table);
//Create the search button
var searchBtn = document.createElement("input");
//Set the attributes
searchBtn.setAttribute("onclick","OnQuery()");
searchBtn.setAttribute("type","button");
searchBtn.setAttribute("value","Search");
searchBtn.setAttribute("name","querybtn");
searchBtn.style.marginLeft = "20px";
searchBtn.style.marginTop = "20px";
//Add the button to the body
document.body.appendChild(searchBtn);
}
function OnUnload()
{
}
Works in jsfiddle in IE 10 & 9 didn't check lower versions

Don't ever use document.write() - it's a really ugly legacy bit of functionality.
HTML tags (since about v4 of html) should be in lower case. There's other things about the code wich are messy - but there is a seperate a StackOverflow site for code review.
There's nothing here which is MSIE speciic - and I strongly encourage you not to wite MSIE specific code - if you write code for Firefox or webkit, then you'll find it much more portable across different targets (including MSIE).
Trying again....
<html>
<script>
function OnQuery() {
alert("Query");
}
function OnLoad() {
var t=false;
if (t = document.getElementById("placeholder")) {
t.innerHTML="<INPUT onclick=\"OnQuery()\" type=\"button\" value=\" Search \" name=\"querybtn\" />";
}
}
if (window.addEventListener) {
window.addEventListener('load', OnLoad, false);
} else if (window.attacheEvent) {
window.attachEvent('onload', OnLoad);
}
</script>
<body style="background-color: #d4d4d4">
<div id="placeholder"></div>
</body>
</html>
While you could explicitly use the DOM createElement and add node stuff - it gets messy and slow when working with plex constructs - HTML fragments and innerHTML are more flexible and faster.
