capture functions in Javascript

HOME ยป Javascript

Hello, I wanted to know whether there is a way for me to capture functions that have been defined in a Javascript file.
It is for testing purposes. I am actually creating a web page where the user would be asked to upload a javascript file and then the list of functions would appear in a drop down list or something for the user to select upon which function he/she wants to perform the test.
Thanking you in advance

Is there a way to see what Javascript functions (the name of the functions) execute in real time in Chrome's Inspector?
Javascript

For example, pretend there is Javascript code that will execute someFunction() when a button is clicked and I click that button. I wonder if there is some way to see that someFunction() was just executed. Is there a way to see what functions are executed in Chrome in real time?


If it is the Profiles tab in the inspector that does the trick, how exactly do you tell what functions fire in real time with that?


EDIT 1/21/2012 12:36p Pacific: From Brian Nickel's comment below, the Timeline tab in the Inspector is the way to see what happens in realtime, but how do you see the names of executed functions in the Timeline?


Running JavaScript functions only after real-time functions fully load?
10/12/2014 2:10 am Javascript

This question is different from waiting for the page to load. On some websites, HTML tags load after certain events occur (JavaScript function loading a query or search, or user needs to scroll down).

When writing your own JavaScript functions to try to edit these tags via window.onload, since the tags technically don't exist yet, the function does nothing.

Placing the functions at the bottom of the body probably won't work, since those tags do not load after waiting a bit of time, but after their associated JavaScript functions create them.

For example, if you wanted to change the grey-black colour of the divs in Google Images after a search (which loads more pictures as you scroll down, but doesn't do anything if you don't), even you attempt to write a GreaseMonkey script to perform actions with window.onload, it would not do anything after scrolling down since it's already loaded.

Would a possible (but crude) solution be to re-run the function each time the user scrolls down (like a mouse listener of sorts)? Or would you recommend another method? Just delaying the function doesn't quite work since it would depend on when the user decides to scroll.


What are the benefits to using anonymous functions instead of named functions for callbacks and paramaters in JavaScript event code?
Javascript

I'm new-ish to JavaScript. I understand many of the concepts of the language, I've been reading up on the prototype inheritance model, and I'm whetting my whistle with more and more interactive front-end stuff. It's an interesting language, but I'm always a bit turned off by the callback spaghetti that is typical of many non-trivial interaction models.


Something that has always seemed strange to me is that in spite of the readability nightmare that is a nest of JavaScript nested callbacks, the one thing that I very rarely see in many examples and tutorials is the use of predefined named functions as callback arguments. I'm a Java programmer by day, and discarding th
