ECMAscript 属性数组的遍历处理

属性数组遍历处理

var flowFile = session.get();
if(flowFile != null) {
    try {
        var hasStr = flowFile.getAttribute('包含的字符')
        var noStr = flowFile.getAttribute('不包含字符')
        var attrName = flowFile.getAttribute('存放属性名')
        var listStr = flowFile.getAttribute(attrName)
        var list = JSON.parse(listStr)
        var res = [];
        for(var i = 0;i<list.length;i++){
            var item = list[i];
            if(item.indexOf(hasStr)>-1){
                if(noStr!='' && item.indexOf(noStr) == -1){
                    res.push(item);
                }
            }
        }
        var resStr = JSON.stringify(res)
        flowFile = session.putAttribute(flowFile, attrName, resStr)
        session.transfer(flowFile, REL_SUCCESS)
    } catch(e) {
        session.transfer(flowFile, REL_FAILURE)
    }
}
