• jquery manipulate a tags with .css()

  - by jesse

  I need to change the font color of a div with the id name "nav" to white. I did: $("#nav").css("color","white"); This works for all the text that isn't wrapped in < a tags but I need those changed too. I tried adding: $("a").css("color","white"); But that doesn't work. I also tried: var changeAColor = document.getElementsByTagName("a") $(changeAColor).css("color","white"); Any ideas appreciated.

• Node.js A Good authentication module ? or whats the proper way to authenticate users?

  - by Mohamed Ahmed

  I'm learning Node.js and looking forward to create a simple web application which will be based on Express and I was thinking of something like creating user groups and each group has its own users and each group has its own permissions (Just like ACL in Cakephp) So can anyone recommend a good module or whatever to do so ? Also I'm a little curious about security and how these passwords are going to be saved and what type of encryption the passwords will be encrypted in. Thanks :)

• Override tablesorter CSS

  - by user1712810

  I am using jquery tablesorter. When the page loads, I have a code to highlight the background color of certain rows in the table. Since tablesorter is used I guess it overrides the css and not allowing to change the background color of the rows. This is the code. This function automatically loads when the page gets loaded. I removed table-sorter to the table and tried this. It works. I have to get it to work with the table-sorter applied. $(document).ready(function() { var row, len, results; row = 0; results = []; while (row < len) { if ($("#tab1 #example_"+row+"chkbx").is(":checked")) { $("#tab1 #example_" + row).css("background-color", "#c6b79f"); } row++; } return results; });

• Print new line in the source-code with jQuery.

  - by Kucebe

  I have a simple function in jQuery that creates new elements in the DOM. the problem is in the html source code, it append every element in the same line, and it's very bad to read. function _loadNewElements(elements){ for(var i=0; i<elements.length; i++){ var fixedElement = $('<img />') var position = elements[i].position; var cssMap = { 'position': 'fixed', 'top': position.top + "px", 'left': position.left + "px" }; fixedElement.css(cssMap); fixedElement.addClass("fixedTag"); fixedElement.attr('alt', elements[i].text); fixedElement.attr('src', "elements/" + elements[i].id + ".png"); fixedElement.appendTo($('#board')); //i'd like to print something here like ("\n"); } } I tried document.write("\n") but in this context it doesn't work. Any solution?

• Is there a way to fix the width of drop down list?

  - by Harry Pham

  Here is what I got: <select id="box1"> <option>ABCDEFG</option> </select> <select id="box2"> <option>ABCDEFGHIJKLMNO</option> </select> I have 2 different Drop Down lists. Since the width of a drop down list depends on the width of the longest text in the option, I end up with 2 drop down lists with 2 different widths. This makes my webpage look goofy. What I want is to set it so that both of my drop down lists will have the same width (I'd prefer the width to be very long, so that even the longest item won't be truncated).

• How can I close a SimpleModal dialog when the user clicks the Back button?

  - by Wally Hartshorn

  When a user clicks on a button or link, I use the SimpleModal jQuery plugin to display a dialog to overlay the entire page, preventing the user from clicking another button or link during the delay before the next page loads. (I'd like to avoid this, but that's an issue for another day.) After the next page displays, if the user clicks the Back button, the previous page still has the SimpleModal overlay displayed, preventing them from using the page. This is a problem. How can I cause the SimpleModal dialog to close automatically either when the leaves the page or when the user clicks the Back button to return to the page? I tried this without success: $("body").unload(function() { $.modal.close(); }); Thanks! Wally

• How to get an embedded function to run multiple times

  - by Guy Montag

  The question I have is how to I get multiple instances of a function to run. Here is my function below - A simple fade function. Problem I'm having is that when it is called a second time it abandons the first call. So if a user clicks on a button it will display a message which fades. If the user clicks on another button the previous fading message just stops at the current opacity level. Try it here - www.arcmarks.com ( please do not repost this domain name) click on SignUp and than quickly click on SignIn with out typing anything. You will see the previous message simply halts. ? What is the stopping mechanism? Where did the previous function go? The function function newEffects(element, direction, max_time ) { newEffects.arrayHold = []; newEffects.arrayHold[element.id] = 0; function next() { newEffects.arrayHold[element.id] += 10; if ( direction === 'up' ) { element.style.opacity = newEffects.arrayHold[element.id] / max_time; } else if ( direction === 'down' ) { element.style.opacity = ( max_time - newEffects.arrayHold[element.id] ) / max_time; } if ( newEffects.arrayHold[element.id] <= max_time ) { setTimeout( next, 10 ); } } next(); return true; }; The Call newEffects(this.element, 'down', 4000 );

• Cached Jquery selector behavior that I do not understand

  - by gaoshan88

  Given the following code why am I getting different values for a and b? I would have thought they would return the same thing: (function() { var a = $('#foo'); var Test = function(){ console.log(a); //outputs 'jQuery()' var b = $('#foo'); console.log(b); //outputs 'jQuery(select#foo)' which is what I want }; })(); This question stems from me trying to stick frequently used selectors into vars. Originally I was doing it in each method (like I did with var b in the above example) but then I found I needed to use the selectors in multiple methods so I moved the assignment out to be available (or so I thought) to all of the methods in that anonymous function. As you can see, it does not work. Why is this?

• Fade out/in sperate divs with button click

  - by user1914298

  I saw a flash website and was curious to now if this is something possible to build using Jquery, obviously not the entire thing. I was more looking to fade out div1 and div2 with a button click. This is the example site: www.justinfarrellyconstruction.com Example: If i come to the homepage and click the portfolio button the Gallery Div will fade out then fade in another image. At the same time the Text div will fade out its content and load the portfolio text. My apologies if this does not make sense, this is all quite new to me and im trying got learn.

• Using Angularjs with server side templates

  - by codecollision

  For SEO purposes the server renders out the full html template for a given URL on initial load. The site uses angularjs which detects the URL route and renders a client template from the JSON API. For example, you navigate to: /blog/post-title Server responds with post-title content. Angular loads, detects route: /blog/:post_slug and begins to load JSON and render client side template from response. Obviously what Angular does is fine when links are followed after the initial load, but on first load it duplicates effort. My question is if there is a clean way to prevent this situation.

• XPath conditional text node selection

  - by Reinderien

  Hi there. I need to construct an xpath string to select all descendants of a certain table with these conditions: The table is a descendant of a form with a specific action attribute value. The selected descendants are text nodes. The text node content can only contain whitespace. It'll probably look something like: //form[@action = "submit.html"]//table//text()[ ...? ] Any tips would be appreciated. Thanks. Edit: For clarity, here is my current (working) compromise: function KillTextNodes(rootpath) { XPathIterate(rootpath + '//text()', function(node) { var tagname = node.parentNode.tagName; if (tagname != 'OPTION' && tagname != 'TH') Kill(node); }); }

• How to get jQuery animateNumber to pull value dynamically?

  - by mcography

  I am trying to implement jQuery animateNumber, and I have it working like the demo just fine. However, I want to modify it so that it pulls the number from the HTML, rather than setting it in the script. I tried the following, but it just shows "NAN." What am I doing wrong? <div class="stat-title animate-number">$16,309</div> <script> $('.animate-number').each(function(){ var value = new Number; // Grab contents of element and turn it into a number value = $(this).text(); value = parseInt(value); // Set the starting text to 0 $(this).text('0'); $(this).animateNumber( { number: value, }, 1000 ) }); </script>

• Why does this log output show the same answer in each iteration?

  - by Will Hancock

  OK, I was reading an article on optimising JS for Googles V8 engine, when i saw this code example... I nearly skimmed over it, but then I saw this; |=; a[0] |= b; a = new Array(); a[0] = 0; for (var b = 0; b < 10; b++) { console.log(a, b) a[0] |= b; // Much better! 2x faster. } a[0] |= b; So I ran it, in my console, with a console.log in the loop and resulted in 15; [15] 0 [15] 1 [15] 2 [15] 3 [15] 4 [15] 5 [15] 6 [15] 7 [15] 8 [15] 9 WHAT?!?! Where the hell does it get 15 from, on every iteration?!?!?! I've been a web dev for 7 years, and this has stumped me and a fellow colleague. Can somebody talk me through this code? Cheers.

• Initializing new instances of a class in a loop, how can I persist an assignment to an event handler

  - by Pydroid

  This is a follow on question from http://stackoverflow.com/questions/3020960/why-is-my-prototype-function-not-returning-the-property-of-the-instance $.getJSON(myjson, function(data) { var json = data; for (i in json) { juuvies[i] = new Juuvy(i,json[i], font, keyfontsize, valfontsize, orbcol, orbkeycol, orbvalcol, paper); juuvies[i].juuv_it(); var mykey = juuvies[i].init_nodes(); juuvies[i].orb.node.onmouseover = function() { console.log(mykey);}; } }); And my init_nodes function, Juuvy.prototype.init_nodes = function() { return this.key; } At this point of time, I get only the last key in the loop, instead of a unique pass each time. Is there a way I can persist the assignment for the event handler?

• How to detect textarea or input type="text" editing?

  - by kavoir.com

  I use this snippet to prevent the user from accidentally navigating away from the editing page: var warning = false; window.onbeforeunload = function() { if (warning) { return ''; } } Now I want to set the variable warning to be true if any of the textarea or input type="text" has been modified, I want to use the onkeyup event such as in: document.getElementById('textarea_id').onkeyup = function() { warning = true; } But it's not working. Don't quite want to use jQuery on this. Any insights?
