...what does it mean? I have almost no experience with jQuery, and need to work with some existing code.
All the tutorials talk about is using $() with pseudo-CSS selectors, but what would be the meaning of something like this:
$(function makeFooWriteTooltip() {
if($("div[name='txttooltip']").length>0){
$("div[name='txttooltip']").each(
function(){

fn is an alias for jQuery. prototype which allows you to extend jQuery with your own functions. For Example: $.fn.
Answer: Use the syntax $. fn. myFunction=function(){} The syntax for defining a function in jQuery is little bit different from the JavaScript.
Similar to JavaScript, to pass a function as a parameter in TypeScript, define a function expecting a parameter that will receive the callback function, then trigger the callback function inside the parent function.
Function parameters are the names listed in the function definition. Function arguments are the real values passed to (and received by) the function.
It's a shortcut for:
$(document).ready(function makeFooWriteTooltip() {
Though, the function need not have a name here. Passing a calback to $() runs the function on the document.ready event, just a bit shorter, these are equivalent:
$(document).ready(function() {
//code
});
$(function() {
//code
});
Also, given your exact example, there's no need to check the .length, if it's there it runs, if not the .each() doesn't do anything (no error), so this would suffice:
$(function () {
$("div[name='txttooltip']").each(function(){
jQuery API tells us:
jQuery( callback ) ( which equals to $(callback) )
