Hello,

There are many ways to achieve this, I am just mentioning few which I have used

You can use System.Web.Script.Serialization.JavaScriptSerializer to serialize the array variable

HTML
```
<script type="text/javascript">
var _jsArr = <%= serializer.Serialize(arrVals) %>;
<script>
```

You can create a string snippet containing the necessary JavaScript code and then use ClientScript.RegisterStartupScript to register the client script block.

C#

StringBuilder sb = new StringBuilder();
sb.Append("<script>");
sb.Append("var _jsArr = new Array;");
foreach(string str in arrVals) {
    sb.Append("_jsArr.push('" + str + "');");
}
sb.Append("</script>");
ClientScript.RegisterStartupScript(this.GetType(), "ArrayScript", sb.ToString());

You can also have a look at this[^] or this[^] article.

Regards,
