C# 调用JS 并为JS变量设置

protected void Button1_Click(object sender, EventArgs e)
        {
            ClientScriptManager csm = this.ClientScript;
            string js = string.Format("window.dialogArguments.document.getElementById('txtEquId').value='{0}';", GetEquIds());
            js += string.Format("window.dialogArguments.document.getElementById('txtEquId').value='{0}';window.close();", GetEquNames());
            csm.RegisterStartupScript(this.GetType(), "sufei", js, true);
        }

<table border="0" cellpadding="0" class="PageBottom" cellspacing="0" id="Table1"
        width="100%" align="center">
        <tr>
