function jsonDateFormat(jsonDate) {
    try {
        var date = new Date(parseInt(jsonDate.replace("/Date(", "").replace(")/", ""), 10));
        var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
        var day = date.getDate() < 10 ? "0" + date.getDate() : date.getDate();
        
 
var hours = date.getHours();
        var minutes = date.getMinutes();
        var seconds = date.getSeconds();
        var milliseconds = date.getMilliseconds();
        return date.getFullYear() + "-" + month + "-" + day + " " + hours + ":" + minutes + ":" + seconds + "." + milliseconds;
    } catch
 
 (ex) {
        return "";
    }
}

調用

var date = jsonDateFormat("/Date(1412043219000)/");

json日期格式轉換為正常格式
