如何调用函数并通过jquery传递变量？

Question

I'm trying to do something like

<button onclick="editUser('<?=id?>')">

I have a jquery function that updates the database with Ajax, but trying to tell the function which Id to update.

Answer 1

Make the HTML something like this instead:

<button id="myButton" data-id="12345678">

When your page loads you'd do:

$("#myButton").click(editUser);

Then in editUser()

var id = $(this).data("id");

Your function now knows the ID you're interested in.
