client side script

[jewel]

Hi,

can anyone show me how to handle client side script with asp.net? make sense? how will client side script communicate with code behind?


Thanks,

Jewel

You can use two methods: Page.RegisterStartupScript to make some js run immediately, or Page.RegisterClientScriptBlock to add some javascript to your page. You generate the javascript in the codebehind with your controls, or whatever logic you want.

Example:

Dim strJS As String
        strJS = "<script language=JavaScript>function selectAll(intAction){" & _
                "if(intAction==0)" & _
                "{"
        For i As Integer = 0 To strArrayA.GetUpperBound(0)
            strJS &= "document.getElementById('" & strArrayA(i).ToString() & "').checked = true;"
        Next
 
        strJS &= "}" & _
                "else" & _
                "{"
 
        For j As Integer = 0 To strArrayD.GetUpperBound(0)
            strJS &= "document.getElementById('" & strArrayD(j).ToString() & "').checked = true;"
        Next
 
        strJS &= "}}</script>"
 
 
 
        Page.RegisterClientScriptBlock("theselectallfunction", strJS)
