I've created dynamic table using HTML and javascript but rather than applying alternate color, I want to apply distinct color to each row. How can I do so?
<!DOCTYPE HTML>
<html>
<head>
<title>Dynamic Page</title>
</head>
<body>
<table>
<tr>
<td>Enter Rows</td>
<td><input type="number" id="txtRows"/></td>
</tr>
<tr>
<td>Enter Columns</td>
<td><input type="number" id="txtCols"/></td>
</tr>
<tr>
<td colspan="2"><input type="button" id="btnDisplay" value="Display" onClick="createTable();"/></td>
</tr>
</table>
<table id="tbl_DynamicTable" border="1">
</table>
</body>
<script type="text/javascript">
function createTable()
{
debugger;
var rows = document.getElementById("txtRows").value;
var cols = document.getElementById("txtCols").value;
var table = document.getElementById("tbl_DynamicTable");
var str="";
for(var i=0;i<rows;i++)
{
str += "<tr id=row" + i +">";
//r = document.getElementById('tbl_DynamicTable').getElementsByTagName('<tr>');
//r.bgColor = colours[(i%k)/group | 0];
//mycurrent_row.style.backgroundColor = "#EEF4EA";
//mycurrent_row.style.backgroundColor =colours[(i%k)/group | 0];
for(var j=0;j<cols;j++)
{
if(i==0)
{
str += "<th> Header " + j + "</th>";
}
else
{
str += "<td> Row " + i + ", Cell "+ j + "</td>";
}
}
str += "</tr>";
}
table.innerHTML = str;
}
$("tr").style("bgcolor","red");
</script>
</html>
I don't know how to use jQuery with HTML page. I'm new to this. So if possible please let me know what is needed to include in this too.

Reset to default 4You have many way to create a random color.
Use these example :
JAVASCRIPT
'#'+Math.floor(Math.random()*16777215).toString(16);
jQuery
(function(m,s,c){return (c ? arguments.callee(m,s,c-1) : '#') +
s[m.floor(m.random() * s.length)]})(Math,'0123456789ABCDEF',5)
And add this hexa random color on your TR when you generate it
HTML
<table border="1">
<tr bgcolor="#FF0000">
^ Here
<th>Month</th>
<th>Savings</th>
</tr>
<tr>
<td>January</td>
<td>$100</td>
</tr>
</table>
Other example on http://www.paulirish./2009/random-hex-color-code-snippets/
javascript approach (i suggest including jQuery):
<script type="text/javascript" src="http://code.jquery./jquery-latest.min.js"></script>
<script type="text/javascript">
function get_random_color() {
var letters = '0123456789ABCDEF'.split('');
var color = '#';
for (var i = 0; i < 6; i++ ) {
color += letters[Math.round(Math.random() * 15)];
}
return color;
}
// paint rows on document ready
$(function(){
paint_rows();
});
function paint_rows() {
$('#table_id tr').each(function(){
$(this).css('color', get_random_color());
});
}
</script>
just make sure to add enough color values into the array colors (can use hex values as well).
and, you can call the function paint_rows() whenever needed of course.
hope that helps.
