[jQuery] search and replace TD innards

[jQuery] search and replace TD innards


I tried to build a plugin that would replace all numbers in td's of a
certain class with numbers formatted with commas.
For instance:
<td>1111</td><td>2222</td>
Would be replaced with
<td>1,111</td><td>2,222</td>
Here's the code... doesn't work for phooey.
When I debug in firebug, the variable 'number' equals (literally):
"function (value) {\n return value == undefined ? this.length ?
this[0].innerHTML : null : this.empty().append(value);\n}"
$(".commas").addCommas();
jQuery.fn.addCommas = function() {
number = '' + this.html;
if (number.length > 3) {
var mod = number.length % 3;
var output = (mod > 0 ? (number.substring(0,mod)) : '');
for (i=0 ; i < Math.floor(number.length / 3); i++) {
if ((mod == 0) && (i == 0))
output += number.substring(mod+ 3 * i, mod + 3 * i + 3);
else
output+= ',' + number.substring(mod + 3 * i, mod + 3 * i + 3);
}
return (output);
}
else return number;
};
