1. JS程式碼

function isEmpty(obj){
    if(typeof obj == "undefined" || obj == null || obj == ""){
        return false;
        //為空的時候返回的就是false
    }else{
        return true;
        //不為空返回true
    }
}

2. 如何在.js檔案中使用

  if (isEmpty(row.originDeployNum) == false) {
                        row.originDeployNum = "";
                    } else if (isEmpty(row.originDeployNum) == true) {
                        row.originDeployNum = "原創+視訊釋出： " + row.originDeployNum;
                    } else {
                    }
