Hi
i have found the solution.
Dim sb As New System.Text.StringBuilder()
sb.Append("<script type = 'text/javascript'>")
sb.Append("$(function dialcode(){")
sb.Append("var code = '+659833834';")
sb.Append("$('[id*=body_txt_mobile]').val(code);")
sb.Append("$('[id*=body_txt_mobile]').intlTelInput({")
sb.Append("autoHideDialCode: true,")
sb.Append("autoPlaceholder: 'ON',")
sb.Append("dropdownContainer: document.body,")
sb.Append("formatOnDisplay: true,")
sb.Append("hiddenInput: 'full_number',")
sb.Append("initialCountry: 'auto',")
sb.Append("nationalMode: true,")
sb.Append("placeholderNumberType: 'MOBILE',")
sb.Append("preferredCountries: ['MY'],")
sb.Append("separateDialCode: true")
sb.Append("});")
sb.Append("});")
sb.Append("</script>")
ClientScript.RegisterClientScriptBlock(Me.GetType(), "dialcode", sb.ToString())
