  • Is it possible to get the current request that is being served by node.js?

    - by user420504
    I am using express.js. I have a need to be able to log certain request data whenever someone tries to log a message. For this I would like to create a helper method like so function log_message(level, message){ winston.log(level, req.path + "" + message); } I would then use the method like so. exports.index = function(req, res){ log_message("info", "I'm here"); } Note that I am not passing the req object to the log_message function. I want that to be transparently done so that the log_message API user does not need to be aware of the common data that is being logged. Is there a way to achieve this with express.js/node.js. Is the request object available from a global variable of some sort?

  • Iterating Through N Level Children

    - by bobber205
    This seems like something neat that might be "built into" jQuery but I think it's still worth asking. I have a problem where that can easily be solved by iterating through all the children of a element. I've recently discovered I need to account for the cases where I would need to do a level or two deeper than the "1 level" (just calling .children() once) I am currently doing. jQuery.each(divToLookAt.children(), function(index, element) { //do stuff } ); This is what I'm current doing. To go a second layer deep, I run another loop after doing stuff code for each element. jQuery.each(divToLookAt.children(), function(index, element) { //do stuff jQuery.each(jQuery(element).children(), function(indexLevelTwo, elementLevelTwo) { //do stuff } ); } ); If I want to go yet another level deep, I have to do this all over again. This is clearly not good. I'd love to declare a "level" variable and then have it all take care of. Anyone have any ideas for a clean efficient jQueryish solution? Thanks!

  • How to refer to the true 'body' of a page? [NOT iFrame body]

    - by Jim
    I have a script that create a new div element. Then, I want to append the div to the body of the page using appendChild method. The script is look like this : var div = document.createElement('div'); div.id = 'newdiv'; document.body.appendChild(div); Unfortunately, the div also appended to the body of iframes. So, my question is, how to refer to the true body of the document, not including the body of the iframes? That way, the div just appended once, to the "true body" of the document. Thanks before, and sorry if my english is bad. :-D

  • Slide Effect happening too many times

    - by Abs
    Hello all, I call this functions on onmouseover and onmouseout for several divs. //Takes effect on divs with id, 62,63,64,65... function slide_it(id){ $('#options_'+id).slideToggle('slow'); } The problem is that if I move my mouse over and then mouse out, then again, mouse over and then mouse out. If I do this several times, the slide effect happens the same number of times I moved my mouse over and out of the div, as expected. But I can't figure out how I can do this once? I can set a variable, but I have several divs that this function is used by and I can't think of a simple way of doing this rather than storing things into an array, but this is messy! I really appreciate any help on this that is simple to implement! Thanks all for any help

  • Append an onClick event to an anchor tag using jquery?

    - by M.Woodard
    I am trying to add an onClick event to an anchor tag ... Previously i had ... <a href="somlink.html" onClick="pageTracker._link(this.href); return false;"> But i am trying to avoid the inline onClick event because it interferes with another script.. So using jQuery i am trying the following code ... <script> $(document).ready(function() { $('a#tracked').attr('onClick').click(function() {window.onbeforeunload = null; pageTracker._link(this.href); return false; }); }); </script> with the html like so <a id="tracked" href="something.html"> So my question is should this be working, and if not what would be the best solution?

  • Embedding script with timeout in case server goes down

    - by vsync
    I need a way to make sure my script won't block the viewed page, if the server serving the script is down (port 80 is blocked for some reason). Currently when I test it and take down the server (Apache), or close the firewall, I see in the browser that it is trying to load the resource (script in that case), without success for long seconds, until it aborts. Is there a nice way to get past this issue?

  • how do I disable options based on the previous selection?

    - by 3r1c
    I have three drop-down menus for each sample shirt; product, colour and grade. Not all products are available in all colours and/or grades. I would like to disable the options that are not available based on the users selection. I've tried using this answer here (using a radio select). Unfortunately, I can't get it to work with an option-selected input. This is what I'm working on - quartus.ca/select-options.html Any guidance would be appreciated.

    I currently have jQuery code that looks like this: if ($.url.param("s") == "error") { $.gritter.add({ title: 'Error!', text: $.url.param('message') }); } I'm checking to see if the request variable s exists in the url (ie. http://example.com/?s=error&message=this%20is%20my%20message and then showing a popup message that contains information from request variable message. The popup works just fine, but the message variable isn't populated, the plugin asks for a string as a value for the text option. What is the proper way to grab the message variable?

  • What happens with $q.all() when some calls work and others fail?

    - by Alan
    What happens with $q.all() when some calls work and others fail? I have the following code: var entityIdColumn = $scope.entityType.toLowerCase() + 'Id'; var requests = $scope.grid.data .filter(function (rowData, i) { return !angular.equals(rowData, $scope.grid.backup[i]); }) .map(function (rowData, i) { var entityId = rowData[entityIdColumn]; return $http.put('/api/' + $scope.entityType + '/' + entityId, rowData); }); $q.all(requests).then(function (allResponses) { //if all the requests succeeded, this will be called, and $q.all will get an //array of all their responses. console.log(allResponses[0].data); }, function (error) { //This will be called if $q.all finds any of the requests erroring. var abc = error; var def = 99; }); When all of the $http calls work then the allResponses array is filled with data. When one fails the it's my understanding that the second function will be called and the error variable given details. However can someone help explain to me what happens if some of the responses work and others fail?

  • Chrome/IE table cell positioning help

    - by Checksum
    I am making a tiny script to make a HTML element editable. When you click on an element, it gets replaced with a textarea, and you can basically enter the new text. When you press enter, the textarea is replaced with the original element with its innerHTML updated. The demo of the script is here: http://iambot.net/demo/editable/ Now the problem is with the inline table editing. It works perfectly on FF 3.6, but on Chrome/Safari, once the value of a cell is updated, the position of the updated cell shifts to the right by the width of a cell.(Just try the demo in Chrome/Safari) It totally messes up the whole table. I am a beginner in CSS and not able to identify where exactly I'm going wrong. Any help/pointers appreciated! Thanks.
