后台vb

  Protected Sub ItemCheckBox_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim i As Integer = 0
        Dim j As Integer = 0
        For i = 0 To Me.rptMainMenu.Items.Count - 1
            Dim cbxAll As CheckBox = rptMainMenu.Items(i).FindControl("cbxAll")
            Dim rptMenuDetail As Repeater = Me.rptMainMenu.Items(i).FindControl("rptMainDetail")
            For j = 0 To rptMenuDetail.Items.Count - 1
                Dim cbxMenuDetail As CheckBox = rptMenuDetail.Items(j).FindControl("cbxMenuDetail")
                cbxMenuDetail.Checked = cbxAll.Checked
            Next
        Next
    End Sub

但是有没有方法可以再前台js中控制的，有的话还请分享下
