I have these HTML elements created by DOM manipulation. They are nested inside the div with className pagination:     I have this event handler to react every time any anchor element is clicked:  $('.pagination a').on('click', (event) =&gt; {   $('.pagination a').removeClass('active');   event.target.className = 'active';   numPage = event.target.innerHTML;   showPage(numPage, studentList) });     I have this function that removes the ul list from the pagination div and creates a new ul element, depending on the numbers of studenst on the list, and append it to the pagination div again (parent1 = pagination div):  function appendPageLinks(stuList) {   let nPages = Math.ceil(stuList.length/10);   const ulCreated = document.createElement('ul');   parent1.appendChild(ulCreated);    for (i = 0; i &lt; nPages; i++) {     if (i &lt; nPages) {       let li = document.createElement('li');       let a = document.createElement('a');       a.textContent = i + 1;       ulCreated.appendChild(li);       li.appendChild(a);       $('a').attr('href', '#');      }    }   let clicked = ulCreated.getElementsByTagName('a')[0];   clicked.className = 'active'; }    This is the HTML after removing and adding the new ul list with all the nested elements:    According to the HTML, they are both the same but my event handler doesn't listen to the event of the new pagination links I created, even though they are nested inside the same elements.  I already tried using a debugger but it doesn't accept the click event and I don't know why. I searched on Google for a reason of this behavior but I think I'm not using the right terminology to find the bug.  Any help would be much appreciate it.  Cheers
I have a bit of code where I am looping through all the select boxes on a page and binding a .hover event to them to do a bit of twiddling with their width on mouse on/off.  This happens on page ready and works just fine.  The problem I have is that any select boxes I add via Ajax or DOM after the initial loop won't have the event bound.  I have found this plugin (), but before I add another 5k to my pages with a plugin, I want to see if anyone knows a way to do this, either with jQuery directly or by another option.
You can reach this IP address  (if my computer is online). I want to assign a domain to it so I wonder how is that possible when I have no DNS? I do own my domain which is ".com". My IP is static.  Thanks Which package to use for presentations? Beamer, Prosper, or Other Disabling IPv6 on Mint and Debian How does one disable IPv6 completely (for all interfaces, resp. for the whole machine?  Keep in mind, I don't want any kind of GUI solution.    OS in question:   Linux Mint 18.x Cinnamon 64-bit GNU/Linux Debian 9.x Cinnamon 64-bit I was trying to make python version 3 as a default version of Ubuntu,  I used nano ~/.bashrc and added the first line of this answer.    Then It just messed up my terminal.  Now when I am clicking on my Terminal or trying to access by ctrl+alt+t, the terminal does open/run. I can only talk to ubuntu using my terminal how could I fix this?  Please advise!  Pls, note that the terminal icon is present, but the terminal does not open when clicked on. How do I get the terminal to open and work?  Update: I deleted that line from .bashrc. However, I still have a problem opening my terminal. I also see this sign on my ubuntu as well.     saying: a problem occurred when checking for the updates ubuntu 18.04 What is the difference between varchar and nvarchar? Adding multiple CKEditor instances in jquery I don't follow understand what this theorem is saying: "Every function $f: A \to{\cal P}(A)$ is not surjective."   Is this saying so for example let A = {1,2,3} then the power set of A is {},{1},{2},{3},{1,2},{1,3},{2,3},{1,2,3} Is this saying that there is no surjective function that takes every element in each of its power sets to atleast 1 element in A?  Is my understanding correct? I just wanted to ask whether there is any command which would work on common shells (bash, dash, kornshell)? It is supposed to check if the line variable contains any part of the path.  if [[ $line =~ "$PWD"$ ]] ;then From what I understand, the  states that there is a fundamental natural limit to how accurately we can measure velocity and momentum at the same time. It's not a limit on equipment but just a natural phenomenon.  However, isn't this just an observational limit? There is a definite velocity and momentum, we just don't know it. As in, we can only know so much about the universe, but the universe still has definite characteristics.  Considering this, how do a wide range of quantum mechanical phenomena work? For example, quantum tunneling - its based on the fact that the position of the object is indefinite. But the position is definite, we just don't know it definitely. Or the famous light slot experiment? The creation of more light slots due to uncertainty of the photon's positions?  What I am basically asking is why is a limit on the observer, affecting the phenomenon he is observing? Isn't that equivalent to saying  because we haven't seen Star X, it doesn't exist? It's limiting the definition of the universe to the limits of our observation! Showing inequality for harmonic series. I want to show that $$\log N&lt;\sum_{n=1}^{N}\frac{1}{n}&lt;1+\log N.$$ But I don't know how to show this. What's the best way to get the last N elements of a Perl array? Prior to doing some benchmarking work how would one free up the memory (RAM) that the Linux Kernel is consuming for its buffers and cache?    Note that this is mostly useful for benchmarking. Emptying the buffers and cache reduces performance! If you're here because you thought that freeing buffers and cache was a positive thing, go and read . The short story: free memory is unused memory is wasted memory. Is the universe really "fine-tuned for life"? I understand what is meant when we say , but I've seen it claimed it's is fine tuned "for life". Is it?  When I look at known or even speculated life in our universe, I see life clinging to a tiny crumbs separated by vast voids. Our life needs baryonic matter, only 5% of the universe. Its density is $10^{-30}  g/cm^3$, but it clumps together leaving vast voids between the clumps. 99% is in stars and black holes and nebula utterly inhospitable to known life.  That leaves the parts "fine tuned for life" to be 0.05% of the universe. The planets, asteroids, and comets seem like just debris separated by  than the life-sustaining clumps preventing life from spreading.  Even that seems to be used very inefficiently. Life requires the energy of a star, but it's spewed out in all directions. We only receive a tiny fraction of it. Similarly, life requires heavier elements created in supernova, but these are also spewed out in all directions. And it took billions of years to develop a being capable of asking "is the universe fine tuned for life?"  It seems like we live on the crumbs of creation warmed by a rounding error of the heat from our star. Taking this view, the universe appears extremely inhospitable to life. It could be a lot better tuned.  Is it that the universe is fine-tuned for life? Or is it that the universe is so large and life requires such an infinitesimal fraction of the universe that it's a near guarantee were we to roll the dice again that some crumb, maybe not even baryonic matter, could develop something complex enough to ask "why is the universe fine tuned for life"? Am I just restating the weak anthropic principle?  I understand this is straying into philosophy. If that's off topic, are my  physical assumptions correct?
