var plugin = function() { var data = { options: { size: "" }, source: { url: "v" } }; if (!hasProp(data, 'url')) { return; } console.log('Do something with it'); } plugin(); function hasProp(obj, prop) { for (var p in obj) { if (obj.hasOwnProperty(p)) { if (p === prop && obj[p] !== '' && obj[p] !== undefined && obj[p] !== null) { return obj; } else if (obj[p] instanceof Object && hasProp(obj[p], prop)) { return obj[p]; } } } return null; } |
