  • Send post request from client to node.js

    - by Husar
    In order to learn node.js I have built a very simple guestbook app. There is basically just a comment form and a list of previous comments. Currently the app is client side only and the items are stored within local storage. What I want to do is send the items to node where I will save them using Mongo DB. The problem is I have not yet found a way to establish a connection to send data back and forth the client and node.js using POST requests. What I do now is add listeners to the request and wait for data I send: request.addListener('data', function(chunk) { console.log("Received POST data chunk '"+ chunk + "'."); }); On the client side I send the data using a simple AJAX request: $.ajax({ url: '/', type: 'post', dataType: 'json', data: 'test' }) This does not work at all in them moment. It could be that I don't know what url to place in the AJAX request 'url' parameter. Or the whole thing might just be the build using the wrong approach. I have also tried implementing the method described here, but also with no success. It would really help if anyone can share some tips on how to make this work (sending POST request from the client side to node and back) or share any good tutorials. thanks.

  • Document.ready() failing on popup

    - by Seth Duncan
    I am using ASP.Net and jQuery/jQuery UI and I am trying to use the datepicker control. It works fine on every page, except when I have to use the popup (to add new data into the database and then i refresh the current page to reflect the new data being entered). It seems that document.ready() is failing when I use the popup. I can invoke the datepicker control manually with adding a click event to fire off the showcalendar function, however I want to try and make it work. Does anyone have any ideas of why a popup would fail document.ready() ? Thanks!

  • OpenLayers: Raise event when map is zoomed or moved by user

    - by David Pfeffer
    I'm using OpenLayers to display OpenStreetMap maps. (Though, I'd assume this should be general enough to work for any map product...) I'm displaying some very sophisticated vector overlays, and the amount and resolution of the features I'm returning from the server via GeoJSON to overlay has proven too much for many computers. What I'd like to do now instead is to only send data befitting the resolution of the current zoom, and fitting the current view port. This should be relatively easy to do using the GetResolution and CalculateBounds methods on the Map object. However, I don't know when to call these methods because I can't find a way to register a function to be called when the user pans the map (changing the view port) or zooms the map (changing the resolution and view port). How can I get a callback when the user pans or zooms the map?

  • Preset value of HTML Forms - iPhone SDK

    - by laura
    Hi. I'm trying to preset the value of a dropdown menu and the value of a text box in an HTML form. As soon as the user taps the button in my iPhone app, it enters the webview and I was hoping to preset one of the dropdown menus and text field. How do I go about this? I want to set the dropdown to value "4" and the text field to "Giro Apps" Here's the relevant HTML form code: <select id="advSrcId" class="list" onchange="showOther($('advSrcId').options[$('advSrcId').selectedIndex].value)" name="advSrcId"> <option selected="" value="">Select</option> <option value="1">Google</option> <option value="2">Facebook</option> <option value="3">Friend Referral</option> <option value="4">Other</option> </select> <div id="otherAdvsrc" style=""> <p> Please give details here: <br/> <input class="text" type="text" value="" name="advsrc"/> <br/> </p> </div> TIA!

    - by pravin
    I am dealing with textarea, and on click of this I am calling one replace function which will remove some specified string in textarea, this is the basic operation. Expected behavior after clicking on textarea 1) At first click : It should remove specified string from textarea Cursor should come at end of string 2) more than one click : - Cursor should come at where ever user clicks in text area Below is my replace function.... function replace(id,transFromDb) { newStr = $("#"+id).val(); var len = null; if(transFromDb == '') { newStr = newStr.replace(Lang.Message27,''); newStr = newStr.replace(Lang.Message28,''); } else { newStr = newStr.replace(Lang.Message28,''); newStr = newStr.replace(Lang.Message27,''); } /* change font weight as bold. */ $("#"+id).css({"fontWeight":"bold"}); $("#"+id).val(newStr); } Assume that Lang.Message is specified string. It's working above behavior with FF. Facing issue on IE, it always keep cursor position at first. Please provide any solution.... Thanks in Adavance Pravin

  • Ruby on Rails - jrails not site wide

    - by Hamish
    Is it possible to configure jrails so that it only replaces the ruby on rails helper methods for some parts of the site? I am currently in a project where we are doing a staggered migration to jQuery so the site wide choice is not an option in this case.

  • JQuery: Push Effect?

    - by JGreig
    I'm currently using the JQuery slideDown/slideUp effect and am not accomplishing what I want. Essentially, I want to create an action where I "push" a div off the top of the browser window. Something similar to the following push effect example. How can I do this with JQuery? The problem with just using slideDown/slideUp is that the other DIV just overlaps the div I'm hiding. But instead, I want to PUSH the div I don't want visible off the top of the browser window.

  • When onblur occurs, how can I find out which element focus went *to*?

    - by Michiel Borkent
    Suppose I attach an onblur function to an html input box like this: <input id="myInput" onblur="function() { ... }"></input> Is there a way to get the ID of the element which caused the onblur event to fire (the element which was clicked) inside the function? How? For example, suppose I have a span like this: <span id="mySpan">Hello World</span> If I click the span right after the input element has focus, the input element will lose its focus. How does the function know that it was mySpan that was clicked? PS: If the onclick event of the span would occur before the onblur event of the input element my problem would be solved, because I could set some status value indicating a specific element had been clicked. PPS: The background of this problem is that I want to trigger an Ajax.AutoCompleter control externally (from a clickable element) to show its suggestions, without the suggestions disappearing immediately because of the onblur event on the input element. So I want to check in the OnBlur function if one specific element has been clicked, and if so, ignore the blur event.

  • Disabling script max-execution-time in flex?

    - by Stefan Kendall
    How do I completely disable the max-execution-time for scripts in flex? The configurable max is 60 seconds, but I'm calling off to other interactive processes which will probably run much longer than that. Is there an easy way to disable the maximum script execution time across my entire application?

  • How to achieve Bing maps like InfoWindow in Google Maps?

    - by BillB
    I'm using Google Maps v3. I really like the InfoWindows found in Bing, as opposed to Google. Screenshots & functionality found here comparing the two: http://www.axismaps.com/blog/2009/07/data-probing-and-info-window-design-on-web-based-maps/ Question: How can I replicate Bing like InfoWindows while using Google Maps v3? UPDATE: To be more specific, what I like about Bing's InfoWindows include: - The pointer dynamically changes sides from left/right/bottom/top, as opposed to Google limited to only have the InfoWindow pointer on the bottom - Bing's InfoWindows use less space - You can configure Bing's InfoWindows to pop up outside of the map bounders so that you don't have to autopan the map to display the marker's InfoWindow

  • Apache tiles and body onload event. Known issue?

    - by Angus
    We're prototyping a new visual framework using Apache Tiles for markup templating. Often the document onload event (actually prototype's dom:loaded event) is getting fired before all DOM objects are actually loaded Is it possible that the tiles templates are loading in an asynchronous fashion and therefore doing an end run around the event handler? Has anyone else had this experience? Can anyone share a robust workaround? thanks in advance

  • How can CSS be applied to components from Google Closure Library?

    - by Jason
    I'm getting my feet wet with Google's Closure Library. I've created a simple page with a Select Widget, but it clearly needs some styling (element looks like plain text, and in the example below the menu items pop up beneath the button). I'm assuming the library supports styles -- how can I hook into them? Each example page in SVN seems to use its own CSS. Abbreviated example follows: <body> <div id="inputContainer"></div> <script src="closure-library-read-only/closure/goog/base.js"></script> <script> goog.require('goog.dom'); goog.require('goog.ui.Button'); goog.require('goog.ui.MenuItem'); goog.require('goog.ui.Select'); </script> <script> var inputDiv = goog.dom.$("inputContainer"); var testSelect = new goog.ui.Select("Test selector"); testSelect.addItem(new goog.ui.MenuItem("1")); testSelect.addItem(new goog.ui.MenuItem("2")); testSelect.addItem(new goog.ui.MenuItem("3")); var submitButton = new goog.ui.Button("Go"); testSelect.render(inputDiv); submitButton.render(inputDiv); </script> </body>

  • Having trouble animating Line in D3.js using and array of objects as data

    - by user1731245
    I can't seem to get an animated transition between line graphs when I pass in a new set of data. I am using an array of objects as data like this: [{ clicks: 40 installs: 10 time: "1349474400000" },{ clicks: 61 installs: 3 time: "1349478000000" }]; I am using this code to setup my ranges / axis's var xRange = d3.time.scale().range([0, w]), yRange = d3.scale.linear().range([h , 0]), xAxis = d3.svg.axis().scale(xRange).tickSize(-h).ticks(6).tickSubdivide(false), yAxis = d3.svg.axis().scale(yRange).ticks(5).tickSize(-w).orient("left"); var clicksLine = d3.svg.line() .interpolate("cardinal") .x(function(d){return xRange(d.time)}) .y(function(d){return yRange(d.clicks)}); var clickPath; function drawGraphs(data) { clickPath = svg.append("g") .append("path") .data([data]) .attr("class", "clicks") .attr("d", clicksLine); } function updateGraphs(data) { svg.select('path.clicks') .data([data]) .attr("d", clicksLine) .transition() .duration(500) .ease("linear") } I have tried just about everything to be able to pass in new data and see an animation between graph's. Not sure what I am missing? does it have something to do with using an array of objects instead of just a flat array of numbers as data?

  • How to refresh parent and ancestor windows after closing the child windows?

    - by truthseeker
    Hi, I have three windows: 1st - main window 2nd - child window - it's opened using window.showModalDialog from 1st widnow. 3rd - window - is an ancestor of 1st window and is's opened from 2nd window using window.showModalDialog.

But there is one more assumption, I don't want to have any post-back during this process. Dose anybody have any idea how to make it?

  • Find window previously opened by window.open

    - by spender
    We've got the following situation, running from a single domain: Page A uses window.open() to open a named window (a popup player). window.open() gives page A a reference to the window. User now reloads page A. The reference to the named window is lost. Using window.open() to "find" the window has the unfortunate side effect of reloading it (undesirable). Is there any other way to get a reference to this window?

  • In XMLHttpRequest, where is error flag variable?

    - by Tiangolo
    In the XMLHttpRequest Spec it says that: The DONE state has an associated error flag that indicates some type of network error or abortion. It can be either true or false and has an initial value of false. Also says something similar about a "send() flag" in an "OPENED" state. It's said in the specification but not in the IDL and when I create a new XMLHttpRequest I can't find those "flags". Where are those boolean variables?

  • remove text in parentheses and the parentheses using .filter() or .slice()

    - by liz
    i have a table with code like this: <tr> <th scope="row">5-17</th> <td>23.6 (22.0-24.0)</td> <td>18.0 (17-20.0)</td> </tr> <tr> <th scope="row">Total 0-17</th> <td>20.6 (8-15.6)</td> <td>16.1 (22.2-24.0)</td> </tr> i am using the following function to find the contents of the table cells and bring it into an array: var l1 = $('#datatable td:nth-child(2)').map(function() { return $(this).text(); }).get(); the table fragment's id is "datatable". this returns properly, however i am putting this array into jqPlot and it cant read the stuff between the parentheses or the parentheses themselves. i need the data to remain in the table however because we are displaying both the table and the chart. i cant reformat (add spans around the content i want to remove etc) because these tables are being generated by another piece of software. i think what i need to do is either slice off after the space or use a regex to find and remove. not sure how to proceed with either of these. thanks!

  • Get the full URI from the href property of a link

    - by Savageman
    Hello SO, I would like to have a confirmation on some point. My goal is to always get the same string (which is the URI in my case) while reading the href property from a link. Example: <a href="test.htm" /> with base_url = http://domain.name/ <a href="../test.htm" /> with base_url = http://domain.name/domain/ <a href="http://domain.name/test.htm" /> with base_url = any folder from http://domain.name/ I need to get http://domain.name/test.htm from the 3 situations above (or any other identical string). After some tests, it appears that my_a_dom_node.href always return the full-qualified URI, including the http://domaine.name, which should be okay for what I want. jQuery has a different behaviour and $(my_a_dom_node).attr('href') returns the content (text) that appears inside the HTML. So my trick is to use $(my_a_dom_node).get(0).href to get the full URI. The question is: can I rely on this?
