How do I pass a JSON object to inline javascript In EJS -

i want send ejs object javascript function. have tried below code didn't work.

<% books.foreach(function(book){ %>     <button onclick="getbookdetails(<%=book %>);" > <%=book.name %></button>   <% }); %> 

my javascript code is

function getbookdetails(book){    //using book object } 

i have tried following stuff also.but didn't help.getbookdetails(<%=json.stringify(book) %>);

please me find mistake.

you can't call getbookdetails(<%=book%>) because <%=book%> evaluated [object object] , not { name: "wind in willows, author: "kenneth grahame" } require.

you're on right lines using json.stringify missed 1 crucial point: using <%= escape html entities. instead - use <%- so:

<% books.foreach(function(book){ %>     <button onclick="getbookdetails(<%-json.stringify(book)%>);"><%=book.name %></button> <% }); %> 

you're fine using <%=book.name%> because should output string.
