Why should I add return false in Phonegap(jquery ajax)?
According to jQuery Events: Stop (Mis)Using Return False, returning false performs three tasks when called: event.preventDefault(); event.stopPropagation(); Stops callback execution and returns immediately when called.

jQuery return false not stopping query from running
When you call return false; from inside a .each() loop you are actually just breaking out of the .each. You need to call return false; somewhere outside of your .each to stop the form submitting, e.g. var doSubmit = true; $('[name^=q1\[\]] option:selected').each(function() { if ($(this).val() < 1) { doSubmit = false; return false; } }); if(!doSubmit) return false;

JQuery mobile handling links (return false)
You may try to set a click event on the links for which you want to prevent a default behavior. In the example below, we add a class special_link to the link for which we want to do something special before being redirected to another page. When we click on the "special" link, we check if a given condition is followed or not before deciding to redirect the user to another page. The redirection (with all the transitions stuffs) to another page (page_2 in our example), is done manually, with the following code: $.mobile.changePage( "#page_2", { transition: "slide", }); Fo more information about the method $.mobile.changePage, you can check the online doc: http://api.jquerymobile.com/jQuery.mobile.changePage/ In following example, if you type a 1 in the text input, you'll not be red

jquery "return false" not working properly inside update panel
I presume you mean by "still hitting the code behind" that the default action of the button is not being prevented. This is because the code never gets to return false because of an error: $("[id*='lblError']").text() = 'Template name is invalid!'; return false; should be $("[id*='lblError']").text('Template name is invalid!'); return false; You have just exposed, however, why return false is a bad way to prevent the default action of an event. It is bad because any errors in the error handler will mean that the default action is not prevented, because return false is the last statement in the handler. If you use event.preventDefault(), all kinds of beautiful things will happen. Chief among them is that you can place the statement earlier in the handler: $("[id*='btnCreate']").live

Javascript function, return true when jQuery click event occurs, else false
You don't get the return value since it is out of scope you can simply call the function when the event fires. iff all you check is if the button was clicked you can be certain the function will only fire on click: function setAnswer() { $("input.btnAnswer[type=submit]").click(function (event) { //do stuff and return true if clicked showHideAnswers(true) });

python how to "negate" value : if true return false, if false return true
Use the not boolean operator: nyval = not myval not returns a boolean value (True or False): >>> not 1 False >>> not 0 True If you must have an integer, cast it back: nyval = int(not myval) However, the python bool type is a subclass of int, so this may not be needed: >>> int(not 0) 1 >>> int(not 1) 0 >>> not 0 == 1 True >>> not 1 == 0 True

Why does jQuery only return integer height if setting a double value clearly renders differently?
Using jquery.height() actually converts it to the actual amount of pixels it is taking up on the screen. You may find, if you iterated through every div on your page a mixture of height 10's and 11's, since you can't render something on only half a pixel, to actually render things that take half a pixel you would need to decide whether it will take a pixel or not. The browser will alternate between which divs do and don't to try and get the best possible result.

Submit jquery form based on return values from php
Two problems I've found (one already mentioned by @Fred in comments) in the following two lines: if ($username==NULL) retutn 'a'; First, your $username will never be null. mysqli_real_escape_string returns string. Second line retutn 'a' is probably a typo as suggested by Fred. Try changing these lines to: if (empty($username)) echo 'a';

Return boolean values in dynamic jQuery based on wp_localize_script
This is a programming logic and syntax issue. You should really search for nice tutorials, like here or similar sites. The PHP and jQuery manuals are a must. You are checking for a string, so it should be if(wplocal.moon === 'on'). With quotes in 'on'. And you do the checks inside the function, not outside: function dynamicAdjust() { if( wplocal.moon === 'on' ){ jQuery('#main-home').css('margin-top', jQuery(window).height()); } }

Why does $.contains() return false?
ReferenceError: event is not defined @ http://fiddle.jshell.net/_display/:44 You forgot to add event as the first argument of the callback function. Additionally, $.contains() expect DOM elements for both arguments - but you are passing a jQuery object as the first argument. Changing it like this fixes the whole issue: $("#info").text("box1 contains box2 ? " + $.contains(openedParent[0], event.target)); Updated fiddle: http://jsfiddle.net/xQyAm/2/

Why does "a"="a" return False
That expression is not legal C#. You aren't getting an error because the FuncEval (the ability to execute code in the watch or immediate windows) uses a different parser with various issues. These issues may eventually be fixed by replacing this parser with Roslyn. EDIT I suspect that the VB.Net parser used by FuncEval doesn't intern strings. If you run this expression outside of FuncEval (eg, LINQPad), it returns true. Second EDIT You have an unprintable character in the first string. Notepad++ shows it as a ? because your text file is using an encoding that doesn't support the character. To find out what it actually is, paste it into this site.

PHP return the value but false
A function can not return multiple values, but similar results can be obtained by (1) returning an array or by (2) passing a variable by reference and storing the value you want returned in that variable. You will need to write your function in a way that it returns an array containing the following: The value you wan't returned A flag that signifies true/false Pass a variable by reference into your function and store the value of the status in that variable. function isMember($uID, $pdo, &statByRef) { $status = getUserStatus($uID, $pdo); if(isAllowed($status['status'])) { return $status['status']; } $statByRef = $status['status']; return false; }

jQuery - get tallest image's height, apply other images' height difference to top margin
Try this: function createGrid() { var imgs = $('.hlist figure > img'); var maxImgHeight = 0; imgs.each(function () { var imgHeight = $(this).outerHeight(); maxImgHeight = maxImgHeight > imgHeight ? maxImgHeight : imgHeight; }); imgs.each(function () { var margin = maxImgHeight > $(this).outerHeight() ? (maxImgHeight - $(this).outerHeight()) : 0; $(this).css("margin-top", (margin + "px")); }); } The first each loop looks for the tallest height and stores it in maxImgHeight, as you originally had planned. The second each loop calculates and applies the margin for each image. The conditional assignment will cause the margin-top for the tallest image to be 0.

Javascript / jQuery - Is there a performance difference between height() and .css({'height'})
Read the Source, Luke. jQuery.prototype.height: //snipped to end: return value === undefined ? // Get width or height on the element, requesting but not forcing parseFloat jQuery.css( elem, type, extra ) : // Set width or height on the element jQuery.style( elem, type, value, extra ); jQuery.prototype.css: return value !== undefined ? jQuery.style( elem, name, value ) : jQuery.css( elem, name ); The difference between the two is what's done before going over the matched elements, and that extra parameter that's passed in .height. What could rationally cause a big slowdown? I've no real idea. Maybe it has to do with optimizations a js engine can do in one, but not the other. More likely than not, the perf test is bad (testing these things correctly is very ha

preventDefault , return false does not work
As I said, this code should fix your problem: $("#fieldsForm").off("submit").on('submit', [your function]); What I am doing above is to remove all bound events and than rebind with the one that I want. There is a couple of reasons the could make the code works, for example: Your are binding the event more than once, so the preventDefault wont't work (but it should). Compatibility issues with the jquery version that you using. Because this bug have been resolved in earlier versions.

Google Analytics and return false
in this context, return false will result in the form submission not happening, because you are providing your own custom form processing function (in this case _gaq.push(['_linkByPost', this]); return false;) but you aren't actually processing the form data. I'm not sure where you heard that you needed return false, but I don't think you do. In fact, unless you're submitting the form via javascript, nothing should happen if you return false. I believe that for LINKS the onclick handler should contain a return false because in this case the default action of navigating away isn't desired, rather the link hit should be recorded then something sent to google then the user should go to the page referenced by the link. On this page at least they aren't using return false in the form's ons

Why does this always return false (nested for loop)
Because you are returning false always. return true is on other scope. You should write your code like this: var shouldDoThis = function(query) { // 1st level var should; documents.forEach(function(section) { // 2nd level section.words.forEach(function(word) { //3rd level if (word.content == query.content) { should = true; return; // you "quit" the 3rd level function. This returns to 2nd level } }); // end of 3rd level }); // end of 2nd level return should; }; // end of 1st level More info: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions_and_function_scope
