SyntaxError: missing variable name?

Question

I have an ejs code to create a temp vector.

 <% var temp=[];
   for (i = 0; i < his.length; i++) { 
        temp[i]=  his[i].temp;
};%>

The variable "his" comming from the server then inside a script tag i have this.

var tempe = <%= temp; %>
console.log(tempe);

I got the SyntaxError: missing variable name

what can I do?

Note: Mozilla debugger shows tempe as

tempe= 76,74,24,29,69,59,44`

Which line throws that error? On the server or on the browser? — JJJ

You need to output the array as an array...

var tempe = <%= temp; %> is going to the browser as tempe = 76,74,24,29,69,59,44 as you're seeing in the debugger. What you really want is:

tempe = [76,74,24,29,69,59,44];

which you can get by doing this:

var tempe = <%-JSON.stringify(temp)%>;

or less neatly, this:

var tempe = [<%= temp; %>];
