Question

I have html code <input onclick="function_name(1)"> and I want to use it in Jquery something like function function_name(i) { alert(i); }. It doesn’t work, any tips? Thank you.

The way your code is written, it should work.

If the function_name isn’t firing, then it could be because you haven’t defined it in the global scope.

For example, if you’re using jQuery, this won’t work because the function isn’t global:

$(document).ready(function() {
    function function_name(i) { 
        alert(i); 
    }
});

But this will, because you’ve made the function global:

$(document).ready(function() {
    // some other code
});

function function_name(i) { 
    alert(i); 
}

Or this will, because you’ve explicitly made it global from inside .ready().

$(document).ready(function() {
    window.function_name = function(i) { 
        alert(i); 
    }
});

Aside from the global issue, I’m not sure why your code would fail from the onclick= attribute.
