how do I use for loop inside script tag in ejs

I try to draw chart, using chart.js.

To get my data, I try to use ejs tags

for example,
in ejs I input html like this, and it works well.

      <p>date: <%= today %></p>

  <p>temperature: <%= data[data.length-1].temperature %>℃</p>



  <h1>5days average temperature</h1>



  <ul>

    <% for(var i = 0; i < 5; i++) {(function (j) {%>

      <li><%= dateList[j] %>%></li>

      <ul><li><%= avgLocTmpList[i] %></li></ul>

    <% })(i);} %>

</ul>

but when I use chart.js, I have to use ejs tags like this inside .

<script>

        var temper0 = '<%= data[0].temperature%>';

        tempList.push(temper0);

        var temper1 = '<%= data[1].temperature%>';

        tempList.push(temper1);

        var temper2 = '<%= data[2].temperature%>';

        tempList.push(temper2);

</script>

I can get data[0].temperature as well inside tag.

but, I hope to use for loop inside .
such as

<% for(var i = 0; i < 5; i++) {

<%= data[i].temperature %>

<% }%>

but I can't handle this.
Is there any option or way to handle this for loop inside ??

Thanks, in advance.

In a similar situation i used this inside script tags and worked!
So try the following and check if it works.

<script type="text/javascript">

   <% data.forEach(function (d) { %>

       console.log("<%= d %>"); // or anything you want to do.    

   <% }) %>

 </script>

Also there is a mistake in your following loop code. Care about opening and closing ejs tags. In the first line you forgot to close the ejs tag.

<% for(var i = 0; i < 5; i++) {

<%= data[i].temperature %>

<% }%>

Use this: <% for(var i = 0; i < 5; i++) { %>
