jQuery函数-重新调用自调用函数

Question

I have a function that is I think is self invoked and I'm trying to figure out how to call it again.

This is how the function is declared:

 jQuery(function setupFormInputHandlers(){
     ...
 }

I try to put setupFormInputHandlers() in the developer tools console but I get an undefined error.

Answer 1

See jQuery document ready

// Passing a named function instead of an anonymous function.

function readyFn( jQuery ) {
    // Code to run when the document is ready.
}

$( document ).ready( readyFn );

//invoke again
readyFn()

Answer 2

$ is just used as alias to jQuery so when you say $('x') you mean jQuery('x')..the main function is overloaded to make it familiar and to allow working with ease... also what you are asking about the function (may be you missed pasting other part)

$(function(){}); or
jQuery(function(){}); 

both are methods of calling anonymous function shorthand for

$(document).ready(function()
{
   //your code
}
);` 

in simple words it means "When the document loading complete register your an anonymous function"
