Thanks all for your replies. I wrote one myself. Please note that this uses jQuery.
Code snippet:
var myList = [
{ "name": "abc", "age": 50 },
{ "age": "25", "hobby": "swimming" },
{ "name": "xyz", "hobby": "programming" }
];
// Builds the HTML Table out of myList.
function buildHtmlTable(selector) {
var columns = addAllColumnHeaders(myList, selector);
for (var i = 0; i < myList.length; i++) {
var row$ = $('<tr/>');
for (var colIndex = 0; colIndex < columns.length; colIndex++) {
var cellValue = myList[i][columns[colIndex]];
if (cellValue == null) cellValue = "";
row$.append($('<td/>').html(cellValue));
}
$(selector).append(row$);
}
}
// Adds a header row to the table and returns the set of columns.
// Need to do union of keys from all records as some records may not contain
// all records.
function addAllColumnHeaders(myList, selector) {
var columnSet = [];
var headerTr$ = $('<tr/>');
for (var i = 0; i < myList.length; i++) {
var rowHash = myList[i];
for (var key in rowHash) {
if ($.inArray(key, columnSet) == -1) {
columnSet.push(key);
headerTr$.append($('<th/>').html(key));
}
}
}
$(selector).append(headerTr$);
return columnSet;
}
