  • How to prevent direct access to my JSON service?

    - by FrankLy
    I have a JSON web service to return home markers to be displayed on my Google Map. Essentially, http://example.com calls the web service to find out the location of all map markers to display like so: http://example.com/json/?zipcode=12345 And it returns a JSON string such as: {"address": "321 Main St, Mountain View, CA, USA", ...} So on my index.html page, I take that JSON string and place the map markers. However, what I don't want to have happen is people calling out to my JSON web service directly. I only want http://example.com/index.html to be able to call my http://example.com/json/ web service ... and not some random dude calling the /json/ directly. Quesiton: how do I prevent direct calling/access to my http://example.com/json/ web service?

  • Is there a jQuery plugin for error messages at top like Twitter?

    - by sami
    I'm looking for a jquery plugin that would create an errors div like what twitter has. The div gets added by the plugin, it stays hidden while it doesn't have content, then when a message gets added to it, it appears at the top (with either a close button option or automatic disappear after an x number of seconds). It's not too difficult to write, but there would be no reason to write it if it's already been done before. Anyone knows of a plugin like that?

  • AJAX Beginner: If then statement

    - by dassouki
    In menu.html, I have my menu items(a href links), let's call them, menu_1, menu_2, .... In map.js displays the contents of a map, it calls an API to display some layers and maps. I have a lot of maps to show but i only want to call the api once. Using AJAX, I was wondering if it's possible to have an if/then or select/case in my js, so that if menu_1 is clicked, then implement map_1 etc. without having the page to reload. The only way I thought I could do this is using Post/get .. so when you click on menu_1 it takes you to page.php?page_id=1 . JS will read that and display the map. I'm new to JS and AJAX so please feel free to butcher me

  • Using max-width = 100% and max-height = 100% on an image, calculate the display width/height

    - by NatalieMac
    I am creating a slideshow for images of various sizes to display centered vertically and horizontally within a canvas area. In my CSS, I set the width and height of the image to 100% so that each image would proportionally fill the canvas. I want the canvas to auto-size itself to fit within the viewer's screensize as the original size of the images is quite large (up to 800 pixels tall). I am using jQuery 1.4, and using the height of the image to calculate the top value for absolute positioning it to the middle of the canvas. I have tried using jQuery to get the .height(), innerHeight(), and outerHeight(), but it always gets the full size of the image. I extracted the DOM element from the jQuery object and tried using .width, .offsetWidth, and .clientWidth, but that too always seems to return the full size of the image. Firebug displays the correct dimensions, so I know there's some way of calculating the actual display height of the image, I just can't figure out what it is. How do you get the actual display height of an image if you've set max-height = 100%? I didn't want to have to calculate and set the height of each image in the js, but if I have to, I will. It just seems like I should be able to set the canvas size and have the images auto-adjust.

  • Change the content type of a pop up window.

    - by Oscar Reyes
    This question brought a new one: I have a html page and I need it to change the content type when the user press "save" button so the browser prompt to save the file to disk I've been doing this in the server side to offer "excel" versions of the page ( which is basically a html table ) <c:if test="${page.asExcelAction}"> <% response.setContentType("application/vnd.ms-excel"); %> What I'm trying to do now is to do the same, but in the client side with javacript but I can't manage to do it so. This is what I've got so far: <html> <head> <script> function saveAs(){ var sMarkup = document.getElementById('content').innerHTML; //var oNewDoc = document.open('application/vnd.ms-excel'); var oNewDoc = document.open('text/html'); oNewDoc.write( sMarkup ); oNewDoc.close(); } </script> </head> <body> <div id='content'> <table> <tr> <td>Stack</td> <td>Overflow</td> </tr> </table> </div> <input type="button" value="Save as" onClick="saveAs()"/> </body> </html>

  • Is it possible to execute a function in Mongo that accepts any parameters?

    - by joshua.clayton
    I'm looking to write a function to do a custom query on a collection in Mongo. Problem is, I want to reuse that function. My thought was this (obviously contrived): var awesome = function(count) { return function() { return this.size == parseInt(count); }; } So then I could do something along the lines of: db.collection.find(awesome(5)); However, I get this error: error: { "$err" : "error on invocation of $where function: JS Error: ReferenceError: count is not defined nofile_b:1" } So, it looks like Mongo isn't honoring scope, but I'm really not sure why. Any insight would be appreciated. To go into more depth of what I'd like to do: A collection of documents has lat/lng values, and I want to find all documents within a concave or convex polygon. I have the function written but would ideally be able to reuse the function, so I want to pass in an array of points composing my polygon to the function I execute on Mongo's end. I've looked at Mongo's geospatial querying and it currently on supports circle and box queries - I need something more complex.

  • jQuery properties - problem

    - by Cristian Boariu
    Hi, I use this plugin: jQuery.i18n.properties I put this code: /* Do stuff when the DOM is ready */ jQuery(document).ready(loadMessage); /* * Add elements behaviours. */ function loadMessage() { jQuery("#customMessage").html("test"); jQuery.i18n.properties({ name:'up_mail_messages', path:'https://static.unifiedpost.com/apps/myup/customer/upmail/upmail_messages/', mode:'both', language:'en', callback: function() { var messageKey = 'up.mail.test'; //alert(eval(messageKey)); jQuery('#customMessage').html(jQuery.i18n.prop(messageKey)); } }); } I do not understand why, in the customeMessage div it prints out: [up.mail.test] instead of the value of it: up.mail.test=messages loaded from en Can anybody show me where i am wrong? I;ve spent about two hours on it without finding any clue... Many Thanks. Ps: here is the message file: https://static.unifiedpost.com/apps/myup/customer/upmail/upmail_messages/up_mail_messages_en.properties

  • JS Url GET vars - problem with encoding

    - by Martin
    Hey there! I'm having a bit of trouble here and I was hoping someone throws me a hint :) I'm getting some GET VARS with JS but I have trouble with non-latin charsets: cyrillic for example. The cyrillic var appears correct in the url but when I retrieve it with JS I get some dummy string. I was wondering of a function similar to "unescape" for such a case. Alternatively, if someone knows a way I could convert a cyrillic string to the same dummy string I get from the URL, it will still do me the trick, since all I need is compare. :) Thanks! Martin

  • Converting an equation into a way java script can interpret it

    - by GeorgeTaylor
    So I have this code that is meant to do this equation: (1 / 15) * arccos(-tan(L) * tan(23.44 * sin(360 * (D + 284) / 365))) and for testing purposes alert it! But for some reason it returns "NaN". I've probably done something really stupid :P var now = new Date(); var start = new Date(now.getFullYear(), 0, 0); var diff = now - start; var oneDay = 1000 * 60 * 60 * 24; var d = Math.floor(diff / oneDay); var lat = position.coords.latitude; var long = position.coords.longitude; var tanlat = Math.atan(lat); var tantwentythree = Math.tan(23.44); var dayplus = d + 284; var sinday = Math.sin(360 * dayplus); var arccos = Math.acos(tanlat); var start = 1 / 15; var equation = start * arccos * tantwentythree * sinday / 365; alert(equation);

  • UIWebView selection

    - by Infinity
    Hello guys! I subclassed the UIWindow to get the clicks from UIWebView. I used a tutorial for this. Here is the link: Tutorial It is working, but after I've got and other tutorial from the writer where he shows how to highlight the text in UIWebView. Here's the second link. But I can't use this second one. I tried to run this code in the - (void)userDidTapWebView:(id)tapPoint; delegate method. This delegate method is called when I tap in the UIWebView. Maybe somebody can help me to correct the script? I would like to get the tapped anchor's link. I tried many different java script, but until now I couldn't get the tapped anchor's link. One of the tries is when I tried to add a function to document.onClick. But I tap an anchor then it needs a second tap to get the anchor and I can't get the link neither with this method.

  • JSON in an AJAX request

    - by Josh K
    I have a PHP API I'm working with that outputs everything as JSON. I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter). When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request. Simplified code: $.ajax ({ type: "POST", url: "http://mydomain.com/api/get/userlist/"+mid, dataType: "json", dataFilter: function(data, type) { /* Here we assume and pray */ users = eval(data); alert(users[1].id); }, success: function(data, textStatus, XMLHttpRequest) { alert(data.length); // Should be an array, yet is undefined. }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); }, complete: function(XMLHttpRequest, textStatus) { alert("Done"); } });

  • jQuery: tabs where the tab/content can be linked to

    - by Ricardo Zea
    My issue is simple. I have already implemented a tab system, and I'd probably spend more time implementing another one with the solution I need, than giving a shot at adapting the code I have, and learn something while asking :) My problem is that the tabs can't be linked to, I need to be able to link to a tab from another website or page, and have that tab get selected upon page load. ie: I have three tabs showing different products, by default tab 1 is active/selected when the page loads. From the home page I want to link to tab 2 but I can't link to tab 2 because it doesn't get selected. Not sure if that makes sense. Tabs: <ul> <li><a href="products.php">Product 1</a></li> <li><a href="products.php">Product 2</a></li> <li><a href="products.php">Product 3</a></li> </ul> <div class="tab_container"> <div id="tab1" class="tab_content">Product 1 info...</div> <div id="tab2" class="tab_content">Product 2 info...</div> <div id="tab3" class="tab_content">Product 3 info...</div> </div> my jQuery: $(document).ready(function() { //Default Action $(".tab_content").hide(); $("ul.tabs li:first").addClass("active").show(); $(".tab_content:first").show(); //On Click Event $("ul.tabs li").click(function() { $("ul.tabs li").removeClass("active"); $(this).addClass("active"); $(".tab_content").hide(); var activeTab = $(this).find("a").attr("href"); $(activeTab).fadeIn(); return false; }); }); Is there a way this code can be adapted to be able to link to any tab from anywhere and have that tab get selected when the page loads? Thanks in advance.

  • Binding jQuery UI plugin after $.load

    - by TomWilsonFL
    I have a function that attaches the jQuery UI DatePicker (with my options) to a passed jQuery object: function bindDatepicker($obj) { if ($obj == null) $obj = $("input.date"); $obj.datepicker( { appendText: '(yyyy-mm-dd)', autoSize: true, changeMonth: true, changeYear: true, closeText: 'Done', dateFormat: 'yy-mm-dd', defaultDate: '+1m', minDate: +1, numberOfMonths: 2 } ); } I call this at the beginning of every page to bind it to input elements: $(function() { bindDatepicker($("input.date")); }); This works fine. My problem comes in when I load form elements using $.load(). I cannot attach the DatePicker to any of the loaded elements. For example: $("#id").load("urlToLoad", function() { bindDatepicker($("input.date")); }); Loads the form elements into a div just fine, but will not attach the DatePicker. Why is this? I am stumped. :( Thanks, Tom

  • navigator.onLine

    - by cf_PhillipSenn
    I'm playing with the incomplete example found at http://www.w3.org/TR/offline-webapps/ But I'm distressed to see comments in it like: "renders the note somewhere", and "report error", and "// …" So, will someone please help me write a valid example? Here's what I've got so far: <!DOCTYPE HTML> <html manifest="cache-manifest"> <head> <script> var db = openDatabase("notes", "", "The Example Notes App!", 1048576); function renderNote(row) { // renders the note somewhere } function reportError(source, message) { // report error } function renderNotes() { db.transaction(function(tx) { tx.executeSql('CREATE TABLE IF NOT EXISTS Notes(title TEXT, body TEXT)', []); tx.executeSql(‘SELECT * FROM Notes’, [], function(tx, rs) { for(var i = 0; i < rs.rows.length; i++) { renderNote(rs.rows[i]); } }); }); } function insertNote(title, text) { db.transaction(function(tx) { tx.executeSql('INSERT INTO Notes VALUES(?, ?)', [ title, text ], function(tx, rs) { // … }, function(tx, error) { reportError('sql', error.message); }); }); } </script> <style> label { display:block; } </style> </head> <body> <form> <label for="mytitle">Title:</label> <input name="mytitle"> <label for="mytext">Text:</label> <textarea name="mytext"></textarea> <!-- There is no submit button because I want to save the info on every keystroke --> </form> </body> </html> I also know that I have to incorporate this in there somewhere: if (navigator.onLine) { // Send data using XMLHttpRequest } else { // Queue data locally to send later } But I'm not sure what even I would tie that too.

  • Best way to detect that HTML5 <canvas> is not supported

    - by brainjam
    The standard way to deal with situations where the browser does not support the HTML5 <canvas> tag is to embed some fallback content, usually a polite version (and sometimes a less polite version) of <canvas>Your browser sucks</canvas> But the rest of the page remains the same, which may be inappropriate or misleading. I'd like some way of detecting canvas non-support so that I can present the rest of my page accordingly. What would you recommend?
