Alfresco JavaScript获取自定义DataList

问题描述：

我创建了一个自定义数据列表，并在其中添加了一些值。现在，我尝试在将由规则触发的脚本中获取数据值。
到目前为止，我很难用以下代码获取名为 test 的自定义数据列表：

I've created a custom datalist and put some values on it. Now I try to get data values within a script that will be triggered by a rule. So far, I've trouble to get the custom datalist named test with this code:

var site = siteService.getSite(document.siteShortName);
var dataLists = site.getContainer("datalists");
var listCompany = dataLists.childByNamePath("test");

似乎它返回一个空对象，但我不知道为什么，我尝试了

It seems that its return a null object but I can't figure it out why, I tried with

"dataLists", 
"datalists" and 
"data-lists"

但仍然为空对象...
编辑：在查看完日志后，我遇到一个错误，指出模型跟踪失败了NamespaceException。

but still null object... After looking int he solr log, I have an error that says that Model tracking failed NamespaceException. Something like my model has already been defined previously

第二个问题：我如何才能访问数据列表中的数据？

Second question: How can I acces to the data inside the datalist? Is getElementById() will work?

test dataList就像：

test dataList is like:

'test'  
  field1: name, 
  field2: company, 
  field3:number, 
  field4: number2

我希望以下脚本可以帮助您解决数据列表问题

I hope the below script will help you to resolve your datalist issue.

var site = siteService.getSite(document.siteShortName);
var dataListsContainer = site.getContainer("datalists");
var dataLists = dataListsContainer.getChildren();

logger.log("Data List length : " + dataLists.length);
for(var x=0;x<dataLists.length;x++)
{
    var dataList = dataLists[x]; //Get the current data list        
    var props = dataList.getProperties(); //Read the data list properties
    var title = props["cm:title"]; //read the datalist's title property
    logger.log("Data List title : " + title);

    if (title.indexOf("<data_list_title_goes_here>") > -1){ //check whether it's the required data list or not

        var dataListItems = dataList.getChildren(); //get the all datalistitems
        logger.log("Total dataListItems : " + dataListItems.length +" for " + title);
        for(var y = 0;y<dataListItems.length;y++) //Iterate all the datalistitems one by one
        {
            var dataListItem = dataListItems[y];
            var dataListItemProps = dataListItem.getProperties();    //Read all the properties of the current datalistitem      
            logger.log(dataListItemProps["namespace:propertyname"]); //read your custom property here
            logger.log(dataListItemProps["namespace:propertyname"]); //read your custom property here
            logger.log(dataListItemProps["namespace:propertyname"]); //read your custom property here
        }
    }       
}
