Sending array data with hidden input field from client side to server side
I have some values that I'm sending with javascript to the server side code via a hidden input field. This works great. However, I want to find an elegant way to split the values up on the server side. What I have below works, but it doesn't seem like a very clean solution.
Client code
var values = '&approved=1&funded=0&winprob=2';document.form1.ipHidden.value = values.toString();
Server code
Dim strValues As String = ipHidden.Value.ToString() Dim strApproved = strValues.Substring(strValues.IndexOf("approved=") + 9, 1)Dim strFunded = strValues.Substring(strValues.IndexOf("funded=") + 7, 1) Dim strWinProb = strValues.Substring(strValues.IndexOf("winprob=") + 8, 1)
As you can see I'm passing the values similar to how they'd be passed in a QueryString. Is there a way to take a string like "strValues = &approved=1&funded=0&winprob=2" and get the values for each key similar to using the QueryString. ie. strApproved = strValues.QueryString("approved")
Thanks for any help.

You can split strValues whenever @ character exists
strValues.Split('@') which will return a string array containing 4 items
1- Nothing
2- approved=1
3- funded=0
4- winprob=2
And you can assign each string to its specified value in the returned string array

I understand how Split will return a string array, butI still don't understand how to get at each value without looping through the array and testing for the existence of the key I want the value for. Is the following the best way to get at these values? Or could the string array be loaded into a SortedList easily? Then I could just reference the SortedList like strApproved = slList.Item("approved"). But how do I load the SortedList without doing something clunky with the InStr and Substring methods?
Dim strArray() = strValues.Split("&") For Each strValue As String In strArrayIf InStr(strValue, "approved") ThenstrApproved = strValue.Substring(9, 1)
ElseIf InStr(strValue, "funded") ThenElseIf InStr(strValue, "winprob") ThenstrFunded = strValue.Substring(7, 1)
End If NextstrWinProb = strValue.Substring(8, 1)
Thanks for the help.

Hi
Perhaps you can try the following code snippet to retrieve the values from the string above.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim strValues As String = "&approved=1&funded=0&winprob=2"
Dim strWinProb As String
Dim strApproved As String
Dim strFunded As String
Dim strArray() = strValues.Split("&")
For Each str1 As String In strArray
If str1 Is Nothing Or str1 = "" Then
Continue For
Else
Dim substrarray() = str1.Split("=")
Select Case substrarray(0)
Case "approved"
strApproved = substrarray(1)
Case "funded"
strFunded = substrarray(1)
Case "winprob"
strWinProb = substrarray(1)
End Select
End If
Next
End SubRegards,
Xun
