How do I append an object (such as a string or number) to an array in JavaScript?

I have an HTML string representing an element: '&lt;li&gt;text&lt;/li&gt;'. I'd like to append it to an element in the DOM (a ul in my case). How can I do this with Prototype or with DOM methods?  (I know i could do this easily in jQuery, but unfortunately we're not using jQuery.)

A little bit of context:  I'm using the jQuery Validation plugin to validate a sign-up form. I now want to implement an ajax call to check whether the user name is available in the system, and I want to make this ajax call only if the userName value is a valid one as per the rules set in $(form).validate();  I want something like:  $("#userName").keyup(function () {     if ($("#userName").isValid()) {         //make ajax called     } });   I searched the documentation but i couldn't identify the solution to my problem.

What's better to use in PHP for appending an array member,  $array[] = $value;   or  array_push($array, $value);   ?  Though the manual says you're better off to avoid a function call, I've also read $array[] is much slower than array_push(). What are some clarifications or benchmarks?

Sometimes I want to post comments that include @-notifications but can't work the names into the comment text organically. In those cases, I write my comment out and then tack on a @JohnDoe at the end, which works just fine.  Well, it did work, until the otherwise-awesome new name autocompleter was introduced. Now I type out @JohnD and hit Tab, and the whole name appears, but I can't submit the comment by pressing Enter anymore. The Enter key just does nothing. And actually, it doesn't matter if I tab-complete the name or not.  I don't think it's just me because it happens on multiple computers, although they're both running Win7 Pro and recent Firefoxes. Also, I would understand &#8212; but disagree &#8212; if this was considered "not a bug, just reword all your comments that end this way."  EDIT: As the ever-intrepid pseudo-employee Tim Stone pointed out in the comments, what I initially reported is a special case of a more general problem: Enter submission of comments fails whenever the tab complete suggestions are being shown.

How do you tell if caps lock is on using JavaScript?  One caveat though: I did google it and the best solution I could find was to attach an onkeypress event to every input, then check each time if the letter pressed was uppercase, and if it was, then check if shift was also held down. If it wasn't, therefore caps lock must be on. This feels really dirty and just... wasteful - surely there's a better way than this?

On a web form, what should happen when the user presses the ENTER key?  I'm writing a sign-up form - name, email, password, sign-up button: the usual sort of thing. Since I'm using JavaScript, and the page does not use the &lt;form...&gt; tag, I have complete control over what happens with each key press. I can make it change the focus, submit the data to the server, validate the field contents, whatever. But what should it do?  Things I'm wondering: should ENTER take the user to the next field (as per TAB key)? Should pressing ENTER while focus is on the final field submit the form?

I have jQuery but I'm not sure if it has any built-in sorting helpers. I could make a 2d array of each item's text, value, and selected properties, but I don't think that javascript's built in Array.sort() would work correctly.

In the formatted preview for Questions &amp; Answers, typing a tag link with an invalid tag name "crashes" the preview. As soon as you type the following the preview stops updating and an error can be observed in the Javascript console.   [tag:+]   Observed in Safari 7 and Chrome 31.   seems related to the business rule of not allowing certain characters in tags, but it sounds like a different bug.

Unfortunately, as a new user I am not allowed to comment. This is why I need to do a new post regarding to this topic:   This is my code in Google Sheets Script:  function onEdit(e) {   if (e.range.getSheet().getSheetName() == 'Tabellenblatt1' &amp;&amp; e.range.getColumn() == 1) {     e.range.offset(0,1).setValue(new Date());   } }   It works perfectly when I enter data in cell 1 manually, but when data is added via API (in this case when data is added via Zapier) it does not work. Anybody can give me a hint why?

I have a simple html block like:  &lt;span id="replies"&gt;8&lt;/span&gt;   Using jquery I'm trying to add a 1 to the value (8).  var currentValue = $("#replies").text(); var newValue = currentValue + 1; $("replies").text(newValue);   What's happening is it is appearing like:  81  then  811  not 9, which would be the correct answer.  What am I doing wrong?

I find I'm doing the Unix / name completion thing where I type a few letters of the username and hit tab when I'm entering comments.  Please consider adding a bit of JavaScript code that:   When focus is on a comment input box When tab is pressed If the preceeding 'word' is 'like' a username in the comment list or post then complete the name (else, tab to the next tab-able element as per normal)
