问题
I've created a html list of buttons/text from an array called items in an .EJS template. How do I pass the specific item's id (item.id) to the button's function so I can send the right data to my api? Thanks.
<!DOCTYPE html>
<html lang="en">
<head>
<title>Menu</title>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
<script type="text/javascript">
function print(id) {
$.ajax({
url: "https://www.example.com/api/1/print",
type: "POST",
data: {
"item_id": id
},
dataType: "json",
success: function (result) {
alert(result);
},
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(thrownError);
}
});
};
</script>
</head>
<body>
<h2>Menu</h2>
<ul>
<% for(item of items) { %>
<li>
<button onclick="print(item.id)">PRINT</button>
<%= item.name %> - <%= item.id %>
</li>
<% } %>
</ul>
</body>
</html>
回答1:
<button onclick="print('<%= item.id %>')">PRINT</button>
is how you would do it in every templating language I have used. After looking at the docs, it appears EJS is the same
