You need to format the data to be sent to a POST string, aka a `&`
separated string, equal to standard query string. The value and key
pairs should be both escaped with encodeURIComponent. Example:
function params(data) {
var m, params = [];
for (m in data) {
if (data.hasOwnProperty(m)) {
params.push(encodeURIComponent(m) + '=' + encodeURIComponent(data[m]));
}
}
return params;
}
xhr.send(params({key1: 'value', key2: value}).join('&'));
