Answer 1

Not sure y do you need this anyway here's a simple example...

$(function(){
    $('#my_button').click(function(){
       alert("buttonClicked");   //Jquery    
    });
});    

function my_func(){
    $('#my_button').click();  //JavaScript    
}

//HTML

<button id="my_button" onclick="my_func();"></button>

Answer 2

Extend your function to jquery, then use it with $

    $.extend({
        my_jsFunc: function() {
            console.log('============ Hello ============');
        }
    });

    $(function(){
        $.my_jsFunc();
    });

Answer 3

您问的是错误的问题，但我认为您要搜索的是：

$.my_func();

Answer 4

the my_func() is just normal function so should be kept outside jquery Dom ready function

$(function() {
    my_func();

});

 // This function should be outside from jquery function
  function my_func(){
       /.. some operations ../
   } 

Answer 5

$(function() {
    function my_func(){
       /.. some operations ../
    }
})

runs the everything inside when the page is "ready".

You don't need that.

Just define the function list this

function my_func(){
   /.. some operations ../
}

PS "How can i call a jQuery function from JavaScript?" is a bad question. jQuery is a library written using Javascript.

Answer 6

You can do it by actually changing the declaration to outside jQuery callback, but if you have some specific purpose following will work for you

$(function() {

    window.my_func = function() {
           /.. some operations ../
    } 
});

//JavaScript
function js_func () {

   my_func(); //== call JQuery function 
}
