I am trying to determine if the selected element is a input type element.  var element = this.getElement(); console(element) =&gt; &lt;input type='text' name='input' value ='test'&gt; or something else   How do I check if selected element is input element.  I searched google and someone said it can be  element.is('input') but it gave me error saying is undefined.   Can anyone help me here? Thanks a lot!
I need a way to determine the type of an HTML element in JavaScript. It has the ID, but the element itself could be a &lt;div&gt;, a &lt;form&gt; field, a &lt;fieldset&gt;, etc. How can I achieve this?
Why is the company email still "at stackoverflow" Noun for "person with intermediate skill" I'm looking for the noun form of "person with intermediate skill". For example, in the context of a particular activity, "person with no skill" might be designated a novice, and "person with much skill" might be designated an expert. However I know of no such word in between these two extremes.   My only thought is amateur, which has a distinct meaning from describing level of skill, although skill level can often be inferred. I'm looking for a better solution.  EDIT: due to the attention this question has received, I'll try to offer some clarification in order to reduce repeat questions.   "Journeyman" would certainly not work. I am a software developer by profession. However the word I'm looking for should hopefully be profession-agnostic. I am trying to designate the skill level of the person that some learning material might be appropriate for. The word that I'm looking for follows the preposition "for".   For Beginners  For [word for intermediate-skilled person] For Experts  Sorry, but even after all the great answers, I'm still learning towards "amateur" even though it is technically incorrect. Also, the word should not be so esoteric that only people with English degrees know what it means. Keep the ideas coming! Terms for collections of animals As I watched the murder of crows sitting on the line above my house this evening, I got wondering where all of the collective nouns for animals (pod of whales, gaggle of geese, pride of lions) came from and why we need so many.    If sheep can be a flock, why can't whales, geese, lions, and crows? Unbounded continuous function on non-compact metric space Suppose $(S,d)$ is a non-compact metric space. Is it possible to construct an unbounded continuous function from $S$ to $\mathbb{R}$? If it is possible, please show the construction method :)  Here's my attempt to solve this problem: Because $S$ is not compact, we can find a neighborhood assignment function $N(x)$ so that a finite cover is not possible. Then each time we can find an uncovered point from the union of neighborhoods before, and change the function by $f(x):=max\{f(x),\text{a function which equals to the indice of this point at that point and gradually vanishes at further points from the selected point}\}$. However I'm concerned that while this function is unbounded, there may be some invalid points for this function (goes to infinity)...  EDIT: As I found out there is a duplicate question, however the elementary solution is not presented in that question, so I still wish to know about this problem. :) iBooks preview not working? I recently converted one of my books into an iBooks format using Author. However when I connected to my iPad and went into 'preview', I saw my device, clicked it, but the 'preview' button to enable the previewing process was faded and I could not click it. Has anyone actually used the preview feature enough to give me some help? Thanks! Is it possible to print a variable's type in standard C++? For example:  int a = 12; cout &lt;&lt; typeof(a) &lt;&lt; endl;   Expected output:  int prove that : $ i = \sqrt {-1}\ $ i have a pretty nasty question. i was glancing through a few olympiad papers and stumbled upon this question:  prove that  $ i = \sqrt {-1}\ $.  i tried the conventional methods namely euler's formula  but could not figure what to do next. how do you actually proceed further? i have checked a few books and a proof is not available.are there any proof available for this Can I sync or transfer save games and settings from one platform to another? I would like to know if the same Minecraft account used on a computer can be used on a different platform like the Xbox 360? I am not asking about playing on each simultaneously as each platform has been purchased - I am asking if you can cross play on multiple platforms with the same account. Basically I would like to know if all the saved stuff and settings from one platform will carry over to another. Post apocalyptic journey in search of knowledge from fallen society (ours) I'm racking my memory for a post-apocalyptic novel that I borrowed from a library maybe 15 years ago, but I'm sure it was published a few years before that though (maybe early 90s?).  I remember a party of people travelling across the flooded USA after some kind of apocalypse (climate change/flooding?). Towards the end of the book the group makes their way to New York(?) and finds a partially flooded library, discovering a set of books that gives hope for the return/rebuilding of society. Sum of reciprocals of numbers with certain terms omitted I know that the harmonic series $1 + \frac12 + \frac13 + \frac14 + \cdots$ diverges. I also know that the sum of the inverse of prime numbers $\frac12 + \frac13 + \frac15 + \frac17 + \frac1{11} + \cdots$ diverges too, even if really slowly since it's $O(\log \log n)$.  But I think I read that if we consider the numbers whose decimal representation does not have a certain digit (say, 7) and sum the inverse of these numbers, the sum is finite (usually between 19 and 20, it depends from the missing digit). Does anybody know the result, and some way to prove that the sum is finite? Create file and its parent directory I know that touch command creates a file:  touch test1.txt   but how I can create a file and its full path?  for example my desktop contains nothing:  ~/Desktop/$ ls ~/Desktop/$   and I want to create 1.txt in ~/Desktop/a/b/c/d/e/f/g/h/1.txt. Can I do this with a simple command like:  $ touch ~/Desktop/a/b/c/d/e/f/g/h/1.txt   instead of create full path manually and then create the file? Why cannot fermions have non-zero vacuum expectation value? Bridged interfaces and VLAN tags Is there a gender-neutral pronoun that can replace “his” or “her”? This post has two parts: (a) a question and (b) a proposal.   (a) Often, particularly while writing technical papers or user's manuals, I have come across a situation where I need to say:      A user of this software may not need to use it from his personal computer. He can use it from a phone or even from his tablet.   I have seen many authors use female pronouns (i.e. “she” and “her”), but lately this trend seems to have ebbed somewhat.   I, and (I suspect) many other authors, do not want to use passive voice to avoid this.   Is there a gender-neutral way to describe the same situation?   (b) If there is none, I would like to propose using “ze” (for “he” or “she”) and “zir” (for “his” or “her”, rhyming with “fir”) as gender-neutral pronouns. I want to know how you feel about these words. Plotting logarithmic regression with gnuplot using PGFPlots I have the data in 001.csv below that I want to plot. I need two plots: one showing the data and another one showing logarithmic regression. I have no problems plotting the line for the data (and also adding a linear regression line) but I just can't manage to get a logarithmic regression line in there. As far as I understand, I need to use gnuplot for this but unfortunately I can't make it work. Any help would be much much appreciated.

If $E[X|Y]=Y$ almost surely and $E[Y|X]=X$ almost surely then $X=Y$ almost surely Assume that $X$ and $Y$ are two random variables such that $Y=E[X|Y]$ almost surely and $X= E[Y|X]$ almost surely. Prove that $X=Y$ almost surely.   The hint I was given is to evaluate: $$E[X-Y;X&gt;a,Y\leq a] + E[X-Y;X\leq a,Y\leq a]$$  which I can write as: $$\int_A(X-Y)dP +\int_B(X-Y)dP$$ where $A=\{X&gt;a, Y\leq a\}$ and $B=\{X\leq a,Y\leq a\}$.  But I need some more hints. ibus Avro in Ubuntu 14.04 LTS I used the instructions given  to install ibus Avro in my ubuntu 14.04 LTS (64 bit) but ibus avro was not installed.
