bootstrap table中时间戳转为datetime格式

{
    field: 'createTime',
    title: 'createTime',
    //获取日期列的值进行转换
    formatter: function (value, row, index) {
        return changeDateFormat(value)
    }}，

//转换日期格式(时间戳转换为datetime格式)
function changeDateFormat(cellval) {
    var dateVal = cellval + "";
    if (cellval != null) {
        var date = new Date(parseInt(dateVal.replace("/Date(", "").replace(")/", ""), 10));
        var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
        var currentDate = date.getDate() < 10 ? "0" + date.getDate() : date.getDate();

        var hours = date.getHours() < 10 ? "0" + date.getHours() : date.getHours();
        var minutes = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes();
        var seconds = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds();

        return date.getFullYear() + "-" + month + "-" + currentDate + " " + hours + ":" + minutes + ":" + seconds;
    }
}
