    Hi guys.. i wanna call javascript function which placed at Master Page from Content Page but failed. 

    Below is my code. Please correct me. TQ

    Master Page (HTML)

    <head>
<script>
    function openNav() {
        document.getElementById("mySidenav").style.width = "350px";
    }
</script>
</head>
<body>
    <span style="cursor: pointer" onclick="openNav()">Open</span>
</body>

    Content Page (Code Behind)

        Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If Page.IsPostBack = False Then

            Page.ClientScript.RegisterStartupScript([GetType](), "CallFunction", "openNav()", True)

        End If

    End Sub

    I test your design and the function call works.  I don't have a mySidenav and you did not share this part of the code so I wrote to the console. 

    <script>
    function openNav() {
        console.log("Hello World");
    }
</script>

    I assume the selector you are using is incorrect or there's a CSS conflict.  I suppose there could be an error too but you have not explained what "failed" means.
