Lets say I have a web app which has a page that may contain 4 script blocks - the script I write may be found in one of those blocks, but I do not know which one, that is ha
I have same issue and found this topic. the above answers can solve those problem, but I don't think them are good plans.
let us think about the real world.
if we use those answers, we have to change our code. you have to change your code style. something like this:
original:
$('form').submit(handle);
hack:
bindAtTheStart($('form'),'submit',handle);
as time goes on, think about your project. the code is ugly and hard to read! anthoer reason is simple is always better. if you have 10 bindAtTheStart, it may no bugs. if you have 100 bindAtTheStart, are you really sure you can keep them in right order?
so if you have to bind same events multiple.I think the best way is control js-file or js-code load order. jquery can handle event data as queue. the order is first-in, first-out. you don't need change any code. just change load order.
