I have following problem. If I generate anhor "load_more_btn" via ajax then click function (the one with alert('test') ) wont work. Why is this happens and how to solve this problem?  &lt;div id="content"&gt;&lt;/div&gt; &lt;div id="load_more"&gt;&lt;/div&gt;          &lt;script type="text/javascript"&gt;         function getPhoto(paramType, param, page){             $.ajax({                 url: "skrypt.php?paramType="+paramType+"&amp;param="+param+"&amp;page="+page             }).done(function(data) {                                             $('#content').html(data);                 var nextpage =page+1;                 $('#load_more').html('&lt;a href="#" id="load_more_btn" data-paramType="'+paramType+'" data-param="'+param+'" data-page="'+nextpage+'"=&gt;Wczytaj więcej&lt;/a&gt;');             });         }          $('#load_more_btn').click(function(){                 alert('test');             });      &lt;/script&gt;
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.
How to prove $\,x^a-1 \mid x^b-1 \iff a\mid b$ How to prove $x^a-1\mid x^b-1 \iff a \mid b$, where $x \ge 2$ and $a,b,x \in \Bbb Z$.  I've tried the following in attempting to solve this:  $$a\mid b \Rightarrow aq=b \Rightarrow x^{aq}=x^b \Rightarrow x^ax^q=x^b$$  Because $x^q \in \Bbb Z$, it follows that $x^a\mid x^b$.  This is as far as I have gotten; any help getting further is appreciated.  Note: It may be that this identity is not true at all? Hide processes from other users based on groups (under Linux)? Is it possible to configure process hiding for certain user groups under a linux system?  For example: Users from group X should not see processes owned by users from group Y in ps/top or under /proc.  Is it possible to configure such a setup with SELinux?  (I vaguely remember a similar feature in the funny grsecurity patch set - but IIRC, it was more generic - and besides, I want to configure a stock linux distro without having to maintain a custom kernel.)  Edit: For better illustration, . The example is not that generic, but one can configure that a user or some users can only see information of their own processes in ps etc. How will learning about philosophy impact real-life? Now that I have Firefox 49 or higher, how do I watch Netflix? Expectation of the maximum of gaussian random variables Let $K$ be a field and $f \in K[x]$ a polynomial of degree $n&gt;0$. Assume that $E$ is an extension of $K$ such that $f$ can be expressed as a product of linear factors over $E$:  $$f(x)=\gamma (x-\alpha_1)(x-\alpha_2)\dots(x-\alpha_n).$$  I want to show that $\lvert K(\alpha_1,\dots,\alpha_2) : K \rvert$ is a divisor of $n!$. I also want to show that if $\lvert K(\alpha_1,\dots,\alpha_n): K \geq (n-1)!$ then $f$ is irreducible over $K$ or $f$ already has a root in $K$.  The problem has a hint. It says: "Use induction on $n=\deg f$. If $f=gh$ in $K[x]$ with $\deg g =r$ and $\deg h=n-r$, then $r!(n-r)!$ is a divisor of $n!$.  Any idea for solving this problem would be appreciated. How would I find the period of an oscillator with the following force equation?  $$F(x)=-cx^3$$  I've already found the potential energy equation by integrating over distance:  $$U(x)={cx^4 \over 4}.$$  Now I have to find a function for the period (in terms of $A$, the amplitude, $m$, and $c$), but I'm stuck on how to approach the problem. I can set up a differential equation:  $$m{d^2x(t) \over dt^2}=-cx^3,$$  $$d^2x(t)=-{cx^3 \over m}dt^2.$$  But I am not sure how to solve this. Wolfram Alpha gives a particularly nasty solution involving the hypergeometric function, so I don't think the solution involves differential equations. But I don't have any other leads.  How would I find the period $T$ of this oscillator? When using Alt+Tab, I can't seem to get back to Skyrim. When clicking its icon or Alt+Tab to get back, I just see an empty window. Windowed mode doesn't allow me to use it in a Windowed (Fullscreen) manner as seen with other games, so that doesn't seem to be an option either. Is there any way to fix this behavior?

Evaluating $\lim\limits_{n\to\infty}(a_1^n+\dots+a_k^n)^{1\over n}$ where $a_1 \ge \cdots\ge a_k \ge 0$ Need to find $\lim\limits_{n\to\infty}(a_1^n+\dots+a_k^n)^{1\over n}$ Where $a_1\ge\dots\ge a_k\ge 0$  I thought about Cauchy Theorem on limit $\lim\limits_{n\to\infty}\dfrac{a_1+\dots+a_n}{n}=\lim a_n$ and something like what happen if all $a_i=0$ or $a_1=\dots=a_k$, but may be something I am thinking wrong?

Is this answer correct? get_post_gallery with Gutenberg I have a site where I created a page that takes the gallery images from a post and puts them into a slider.   I used the following code:  // gets the gallery info $gallery = get_post_gallery( $post-&gt;ID, false ); // makes an array of image ids $ids = explode ( ",", $gallery['ids'] );   Then I inserted the images using wp_get_attachment_image().   Unfortunately, with WP 5.0 and Gutenberg, get_post_gallery no longer works with newly added content. It seems that get_post_gallery used a shortcode that no longer works with Gutenberg.   I am still getting up to speed on Gutenberg and the block system. Until I understand that all better, I was wondering if anyone has any advice on how to get the image ids from a gallery in Gutenberg? Is there any way to keep a command from being added to your history? I have a command that I want to keep out of my history file, and I really don't care to have it there when I search the history stored in memory, though that's less of a concern. Is there any way to prevent this, or do I just have to go back and edit my history file.  update: I didn't realize this might be shell-specific. My shell is zsh.

Determining the name of the VMware host of a VM guest - from the guest Struct padding in C++ Issues Doing a String Comparison in LINQ I'm not normally a fan of mac software implementations, but recently I saw a copy of Parallels Desktop for mac that I was very much impressed by. I looked into parallel's offerings for Linux (I was initially excited that they developed for *nix) but found that it has essentially the same features as VMware.   Does anyone know if there is a software solution for linux that offers the level of integration that the current Parallels Deesktop for mac has?  I looked into wine for the programs I want to run and was very frustrated. I feel like all the ratings in their application database were fabricated honesty. I've tried wine once every Ubuntu release since 8.10 and have never gotten it to work stably.
