i'm working with xpages and javascript server side i want to convert the fields in format json then i parse this dat and i put them in a grid,the problem is that these fields can contains values :one item or a list how can i convert them in json ? this is my code :
this.getWFLog = function ()
{
var wfLoglines = [];
var line = "";
if (this.doc.hasItem (WF.LogActivityPS) == false) then
return ("");
var WFLogActivityPS = this.doc.getItem ("WF.LogActivityPS");
var WFActivityInPS = this.doc.getItem ("WFActivityInPS");
var WFActivityOutPS = this.doc.getItem ("WFActivityOutPS");
var WFLogDecisionPS = this.doc.getItem ("WF.LogDecisionPS");
var WFLogSubmitterPS = this.doc.getItem ("WF.LogSubmitterPS");
var WFLogCommentPS = this.doc.getItem ("WF.LogCommentPS");
var WFLogActivityDescPS = this.doc.getItem ("WF.LogActivityDescPS");
var Durr =((WFActivityOutPS-WFActivityInPS)/3600);
var json= {
"unid":"aa",
"Act":WFLogActivityPS,
"Fin":WFActivityOutPS,
"Durr":Durr,
"Decision":WFLogDecisionPS,
"Interv":WFLogSubmitterPS,
"Instruction":WFLogActivityDescPS,
"Comment":WFLogCommentPS
}
/*
*
* var wfdoc = new PSWorkflowDoc (document1, this);
histopry = wfdoc.getWFLog();
var getContact = JSON.parse(histopry );
*/ }
Careful. Your code is bleeding memory. Each Notes object you create (like the items) needs to be recycled after use calling .recycle()
.
There are a few ways you can go about it. The most radical would be to deploy the OpenNTF Domino API (ODA) which provides a handy document.toJson()
function.
Less radical: create a helper bean and put code inside there. I would call a method with the document and an array of field names as parameter. This will allow you to loop through it.
Use the Json helper methods found in com.ibm.commons.util.io.json they will make sure all escaping is done properly. You need to decide if you really want arrays and objects mixed - especially if the same field can be one or the other in different documents. If you want them flat use item.getText();
otherwise use item.getValues()
There's a good article by Jesse explaining more on JSON in XPages . Go check it out. Hope that helps.
If an input field contains several values that you want to transform into an array, use the split
method :
var WFLogActivityPS = this.doc.getItem("WF.LogActivityPS").split(",")
// input : A,B,C --> result :["A","B","C"]
