使用：直接调用recordLog方法即可

    1. var getStackTrace = function () {
    2.     var obj = {};
    3.     Error.captureStackTrace(obj, getStackTrace);
    4.     return obj.stack;
    5. };
    6. function recordLog(msg) {
    7.     var stack = getStackTrace() || ""
    8.     var matchResult = stack.match(/\(.*?\)/g) || []
    9.     var line = matchResult[1] || ""
    10.     logData(msg + line);
    11. };
