This is probably related to the ‘Getting Wait Cursor to Display’ issue. I have a loop that loads an array that will be a source for a grid. While loading I want to check if a photo exists for the data points in each row of the array. I am using PhoneGap’s File system Plugin. Everything works, but the timing and sequence is off such that the array loads before the photo exists function can return a value for each row. There are two rows evaluated below. Any guidance would be appreciated.
Sub gridDisplay_dataHandler(transaction, result)
gLastNumber = 0
DBRecords=result
data=[]
If DBRecords.rows.length > 0 Then
For i=0 To DBRecords.rows.length-1
picExists = "No"
row={}
record=DBRecords.rows.item(i)
row["id"] = i;
row["DISPLAYNBR"] = record["DisplayNbr"]
varPicture = Trim(gSelectedBroker) & "-" & Trim(record["Principal"]) & "-" & Trim(gSelectedChainNumber) & "-" & Trim(gSelectedStoreNumber) & "-" & CStr(Year(varDate)) & PhotoMonth & PhotoDay & "-" & CStr(record["DisplayNbr"])
varPicture = gfolder & "/" & varPicture & ".jpg"
console.log(varPicture) ' correctly Concatenated Line#:5914
gfileSystem.root.getFile(varPicture, {create: False}, FileEntryExists, FileEntryFails)
console.log(picExists) ' reads "No" Line#: 5914
row["PIC"] = picExists
data[i] = row
Next
source = {localdata: data, datatype: "array"}
dataAdapter = new $.jqx.dataAdapter(source)
NSB.jqxSettings["gridDisplay"].source = dataAdapter
$("#gridDisplay").jqxGrid(NSB.jqxSettings["gridDisplay"])
Else
btnAddDisplay_onclick()
End If
End Sub
Function FileEntryExists()
picExists = "Yes"
console.log("I am here in exists:" & picExists) ' Line#: 5944
End Function
Function FileEntryFails()
picExists = "No"
console.log("I am here in Fails:" & picExists) ' Line#:5950
End Function
