help with value in asp.net

[CesarePlay]

I need a value in asp.net to be ready in javascript. Can anyone help with this? I use vb.net 2003.

Your question is too vague to receive a useful answer; please define it better.

Ok. I have created a function in the code behind called checkdata() . This function checks what sector was selected.

I have also created a javascript function in the html part which calls this function and the checks to see if the fields have been selected. At the moment the problem is the values are not corresponding. The error only occurs when I try save the data and not before.

Ok. Here is the code: SAorry for delay. I spotted one mistake:

Here is the the case pointing to the other vb function

Code: Select all

        Select Case Request.Form("txtcheck")
            Case "Check"
                Call safetydata()
        End Select

The second vb code:

Code: Select all

   Private Sub safetydata()
        Dim check As String

        If Request.QueryString("sector") = "S" Then
            Show.Visible = False
            txtaction.text = "S"
        Else
            If Request.QueryString("sector") = "E" Then
                Hide.Visible = False
                txtaction.text = "E"
            End If
        End If
        check = Request.QueryString("sector")

    End Sub

The javascript code:

Code: Select all

			var check
			if (document.Form1.txtcheck.value = "Check"){
			document.Form1.txtAction == check
			check == "safetydata"
			}
			
			window.onload = function()
			{
				if (check == "S"){
				alert(document.getElementById("Hide").tagName);
				
				}
			else {
				if (check == "E"){
				alert(document.getElementById("Show").tagName);
				}
			  }
			}
			alert(check)
			if (check == "E"){  
				if (document.Form1.lstSeverity.selectedIndex == 0 && canSubmit){
						alert("Please select a Severity.")
						document.all.ViewRC1.style.display = "block"
						canSubmit = false
						document.Form1.lstSeverity.focus()
				}
			}
			else {
			if (check == "S"  && canSubmit){
						alert("Please classify the incident.")
						document.all.safety.style.display = "block"
						canSubmit = false
				}
			}

At the moment it seems better but now won't stop saying I have not classified the incident even though I have.

Now that you have posted some code someone with more vb and JavaScript experience than me can give it a shot

I thought I solved it but still not working

[CesarePlay]

I solved it. After extensive searching on google I found a solution on page 4.

Here is the solution:


In the page_prerender

Code: Select all

txtcheck.Value = Request.QueryString("sector")

txtcheck was the name of the hidden input box

I declared it as: Protected WithEvents txtcheck As System.Web.UI.HtmlControls.HtmlInputControl

The javascript code is:

Code: Select all

var check = document.getElementById("txtcheck").value;

This gets the value stored in the input field.

Here is the code that validates the checkboxes I needed done earlier yesterday:

Code: Select all

if (check == "E"){  
				if (document.Form1.lstSeverity.selectedIndex == 0 && canSubmit){
						alert("Please select a Severity.")
						document.all.ViewRC1.style.display = "block"
						canSubmit = false
						document.Form1.lstSeverity.focus()
				}
			}
			else {
				if (check == "S" && canSubmit){
					if (!document.Form1.chkCloseCall.checked == true && !document.Form1.chkHPI.checked == true && !document.Form1.chkInjury.checked == true && !document.Form1.chkNonComp.checked == true && !document.Form1.chkPropDamage.checked == true && canSubmit){
						alert("Please classify the incident.")
						document.all.safety.style.display = "block"
						canSubmit = false
						return false
					}
				}
			}

Basically my code was right yesterday but because the value never passed through it did not work but now it works.

Edit: html code for it was: <input type="hidden" id="txtcheck" runat="server">
