• NodeJS vm.runInThisContext() and lack of __filename

  - by rFactor

  Whenever I run vm.runInThisContext(code, filename), the ran code reports __filename and __dirname as undefined. This also leads to the situation that any fs.readFile and such calls will not work with relative paths. For example this does not work: fs.readFile('../file', fn); because it does not know where to relate the path to. Specifying the filename as /home/full/path/to/file.js for vm.runInThisContext function does not seem to matter at all. How can I make Node to understand the path to the file?

• AngularJS: download pdf file from the server

  - by Bartosz Bialecki

  I want to download a pdf file from the web server using $http. I use this code which works great, my file only is save as a html file, but when I open it it is opened as pdf but in the browser. I tested it on Chrome 36, Firefox 31 and Opera 23. This is my angularjs code (based on this code): UserService.downloadInvoice(hash).success(function (data, status, headers) { var filename, octetStreamMime = "application/octet-stream", contentType; // Get the headers headers = headers(); if (!filename) { filename = headers["x-filename"] || 'invoice.pdf'; } // Determine the content type from the header or default to "application/octet-stream" contentType = headers["content-type"] || octetStreamMime; if (navigator.msSaveBlob) { var blob = new Blob([data], { type: contentType }); navigator.msSaveBlob(blob, filename); } else { var urlCreator = window.URL || window.webkitURL || window.mozURL || window.msURL; if (urlCreator) { // Try to use a download link var link = document.createElement("a"); if ("download" in link) { // Prepare a blob URL var blob = new Blob([data], { type: contentType }); var url = urlCreator.createObjectURL(blob); $window.saveAs(blob, filename); return; link.setAttribute("href", url); link.setAttribute("download", filename); // Simulate clicking the download link var event = document.createEvent('MouseEvents'); event.initMouseEvent('click', true, true, window, 1, 0, 0, 0, 0, false, false, false, false, 0, null); link.dispatchEvent(event); } else { // Prepare a blob URL // Use application/octet-stream when using window.location to force download var blob = new Blob([data], { type: octetStreamMime }); var url = urlCreator.createObjectURL(blob); $window.location = url; } } } }).error(function (response) { $log.debug(response); }); On my server I use Laravel and this is my response: $headers = array( 'Content-Type' => $contentType, 'Content-Length' => strlen($data), 'Content-Disposition' => $contentDisposition ); return Response::make($data, 200, $headers); where $contentType is application/pdf and $contentDisposition is attachment; filename=" . basename($fileName) . '"' $filename - e.g. 59005-57123123.PDF My response headers: Cache-Control:no-cache Connection:Keep-Alive Content-Disposition:attachment; filename="159005-57123123.PDF" Content-Length:249403 Content-Type:application/pdf Date:Mon, 25 Aug 2014 15:56:43 GMT Keep-Alive:timeout=3, max=1 What am I doing wrong?

• jQuery tools tabs fade effect

  - by kielie

  Hi guys, I used jQuery tools to create a tabs setup, and I would like to incorporate the fade effect, but when I try to do so, it bombs out, here is my code: $(function() { $("#flowtabs").tabs("#flowpanes > div", { history: true, effect: 'fade' }); }); I am assuming that it's because I am also enabling the tabs history? I am kinda new to all of this, so please be patient! :-) Thanx in advance!

  Is there any way to combine all of this to reduce the amount of js? This is just an example of some of the jquery dialogs I have in my site, there are a few more too.

• Need Magic jQuery Replacement for Selectbox Dropdown Form Element. Thank you!

  - by PlasmaFlux

  Hello! I'm stuck on a problem and, after what seems like days of searching for a solution, I'm reaching out to Stack Overflow for help. I'm trying to replace a standard dropdown form element with a Textbox and a Div containing an unordered list. I'd prefer to have the solution be based on jQuery, but am open to alternatives. I've found a couple jQuery plugins that -almost- do what I need, but are far enough from being a real solution that I need to keep looking. Here's an image of what I'm going for: I'd like the dropdown to look as pictured, and when an element is selected (with mouse or keyboard), have just the first line handed back into the textbox (and not be editable). I'd also like to populate a hidden input field with a value that will be used on Submit. I'm pulling my hair out over this one. Any help and guidance will be most appreciated! Thanks! ~PF

• Why should I reuse XmlHttpRequest objects?

  - by Xavi

  From what I understand, it's a best practice to reuse XmlHttpRequest objects whenever possible. Unfortunately, I'm having a hard time understanding why. It seems like trying to reuse XHR objects can increase code complexity, introduce possible browser incompatibilities, and lead to other subtle bugs. After researching this question for a while, I did come up with a list of possible explanations: Fewer objects created means less garbage collecting Reusing XHR objects reduces the chance of memory leaks The overhead of creating a new XHR object is high The browser is able to perform some sort of network optimization under hood But I'm not sure if any of these reasons are actually valid. Any light you can shed on this question would be much appreciated.

• jQuery Ajax form submit, to call php login script

  - by Stevie Jenowski

  Thanks for checking out my problem... I'm having trouble submitting a login form via Ajax for a php script to run and return a new set of html items which will be replacing the HTML in #userlinks.... heres what I have so far $("#login_form").submit(function() { return false; }); $('#login_button').click(function(event) { $form = $(this).parent("form"); $.post($form.attr("action"), $form.serialize(), function(data){ $('#userlinks').html(data); }); }); The php script checks for post data of username && password, yet all I'm getting is a page refresh and no changes. Nothing returns unless I turn login_button into a link and change the script a bit... Any help would be appreciated!

• IE7 is making my life miserable! Getting gaps between html table columns (w/ colspan) with css togg

  - by Art Peterson

  Copy/paste this html code snippet and try it out in IE7. When you toggle the hidden columns it leaves a gap between the columns. In Firefox it works fine, the columns touch when minimized. Haven't tried IE8 yet, would be curious to hear how it works there. Any ideas? I've tried a bunch of things in the CSS like table-layout:fixed but no luck. Note: Not looking for a different toggling method because the table I'm really dealing with is 50+ columns wide and 4000+ rows so looping/jquery techniques are too slow. Here's the code - if someone can re-post a working version of it I'll instantly give them the check and be forever in your debt! <DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <script> function toggle() { var tableobj = document.getElementById("mytable"); if (tableobj.className == "") { tableobj.className = "hide1 hide2"; } else { tableobj.className = ""; } } </script> <style> table { border-collapse: collapse; } td, th { border: 1px solid silver; } .hide1 .col1 { display: none; } .hide2 .col2 { display: none; } </style> </head> <body> <input type="button" value="toggle" onclick="toggle();" /> <table id="mytable"> <tr> <th>A</th> <th colspan="2">B</th> <th colspan="2" class="col1">B1</th> <th colspan="2">C</th> <th colspan="2" class="col2">C1</th> </tr> <tr> <td>123</td> <td>456</td> <td>789</td> <td class="col1">123</td> <td class="col1">456</td> <td>789</td> <td>123</td> <td class="col2">456</td> <td class="col2">789</td> </tr> </table> </body> </html>

• safari and gzip

  - by brad

  I'm loading jQuery from google on my site (http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js) which is minned and gzip'd. In firefox, the jquery file shows as a 19k request, but Safari shows it as a 56k request. I'm assuming then that Safari is not accepting it as a gzip'd file. What's the deal? It's coming from google and I'm pretty sure it's supposed to be gzip'd

• How to match multiple substrings in jQuery combobox autocomplete

  - by John R

  I found more than a couple examples of this with a plain jquery autocomplete but not in a way that will work with the autocomplete included in the combobox code from the demo because the structure of the code is structured so differently. I want to match every item that has all of the search tokens anywhere in any word. I don't need to match the start of any word, any part of it is fine. I don't care if the search strings are highlighted in the autocomplete list if that makes things too complicated. Desired search/result combos: (please excuse the spacing) "fi th" "fi rst second th ird" "rs on" "fi rs t sec on d third" "ec rd" "first s ec ond thi rd" but not limited to any max/min length or number of tokens. EDIT I figured part of it out using the code structure from the other autocorrect I had working. source: function( requestObj, responseFunc ) { var matchArry = $("select > option").map(function(){return this.innerHTML;}).get(); var srchTerms = $.trim(requestObj.term).split(/\s+/); // For each search term, remove non-matches $.each (srchTerms, function (J, term) { var regX = new RegExp (term, "i"); matchArry = $.map (matchArry, function (item) { if( regX.test(item) ){ return{ label: item, value: item, option: HTMLOptionElement } ? item :null; } } ); }); // Return the match results responseFunc (matchArry); }, and select: function( event, ui ) { ui.item.option.selected = true; self._trigger( "selected", event, { item: ui.item.option }); $("destination").val(ui.item.value); // I added this line }, but I can't get both multiple words AND being able to click to select working at the same time. If I remove the } ? item :null; on the return in the map function I can click to select an item. If I leave it I can type multiple words, but I can't click any of the items... Is that the problem or the option: this? I've tried replacing it with HTMLOptionElement and null and I'm stuck. I am able to set the value of another field with ui.item.value within the select label but that doesn't put the value in the search box or close the dropdown menu. Fiddle of current code: http://jsfiddle.net/eY3hM/

• RegEx to replace html entities

  - by DeltaFox

  Hi, all. I'm looking for a way to replace the bullet character in Greasemonkey. I assume a Regular Expression will do the trick, but I'm not as well-versed in it as many of you. For example, "SampleSite.com • Page Title" becoming "SampleSite.com Page Title". The issue is that the character has already been parsed by the time Greasemonkey has gotten to it, and I don't know how to make it recognize the symbol. I've tried these so far, but they haven't worked: newTitle = document.title.replace(/•/g, ""); newTitle = document.title.replace("•", ""); //just for grins, but didn't work anyway
