  • [JS/jQuery] Using argument (this) passed via element eventhandler

    - by Kel
    Hey guys, I want to use the argument I pass (this) in a JS function and treat it as an jQuery variable. Example: <script> function useMe(obj){ $(obj).val(); ... ... ... } </script> <select id="selectid" onChange="useMe(this)"> <option>......</option> </select> Is there a possibility to treat the passed argument as a jQuery element? Btw. I need to do it this way, because the select-element isn't created on load. The select element will be created later asynchronously. So, this won't work: $("select").each(function (i){ var select_id = $(this).attr("id"); $(this).change(function(e){ because it doesn't exist yet. Thanks for your help.

  • How to Refresh / Reload a KML layer in OpenLayers. Dynamic KML Layer.

    - by Ozaki
    TLDR See my answer below on how to refresh the layer. So far I have tried action function as follows: function RefreshKMLData(layer) { layer.loaded = false; layer.setVisibility(true); layer.redraw({ force: true }); } set interval of the function: window.setInterval(RefreshKMLData, 5000, KMLLAYER); the layer itself: var KMLLAYER = new OpenLayers.Layer.Vector("MYKMLLAYER", { projection: new OpenLayers.Projection("EPSG:4326"), strategies: [new OpenLayers.Strategy.Fixed()], protocol: new OpenLayers.Protocol.HTTP({ url: MYKMLURL, format: new OpenLayers.Format.KML({ extractStyles: true, extractAttributes: true }) }) }); the url for KMLLAYER with Math random so it doesnt cache: var MYKMLURL = var currentanchorpositionurl = 'http://' + host + '/data?_salt=' + Math.random(); I would have thought that this would Refresh the layer. As by setting its loaded to false unloads it. Visibility to true reloads it and with the Math random shouldn't allow it to cache? So has anyone done this before or know how I can get this to work? TLDR See my answer below on how to refresh the layer.

  • Two AJAX asynchronus GET call: Only one get the xml file

    - by Woho87
    Hi! I have two AJAX GET calls that are set to asynchcronus = true; I want to obtain two XML files on my server. The two AJAX calls and rendering are defined in function foo & koo. And are called simultaneously. function foo(){ var xmlhttp = new XMLHttpRequest(); xmlhttp.onreadystatechange = function(){ if(xmlhttp.readyState == 4 && xmlhttp.status == 200){ var xmlDoc = xmlhttp.responseXML; //Do something } } xmlhttp.open('get', 'url', true); xmlhttp.send(); } function koo(){ //Almost the same as function foo } foo(); koo(); I've noticed that inside the if statement in the first function call(foo), the code their will never compile. While in the second function call(koo). The code inside the if statement can be compiled. If I set both asynchronus to false, then there is no problem at all. If I remove the second function call(koo) from the code, than the code inside the if statement can be compiled. What can I do to have both asynchronus AJAX calls?

  • Sanitize input before executing at server in php

    - by Interfaith
    I want to let user input two variable, Name and Password in a form. I want to disable any XSS or script insert in the input values. I have the following code in the form method: <form name="form1" method="post" action="checkpw.php"> Your Name: <table> <tr><td><input class="text" name="name" onBlur="capitalize(this);" maxlength=12 type="text" /></td></tr> </table> Password: <table> <tr><td><input class="text" name="passwd" maxlength=8 type="password" /></td></tr> <tr><td align="center"><br/> <input class="text" type="submit" name="submitbt" value="Login" /> </td></tr> </table> and the following checkpw.php: <?php // Clean up the input values $post = filter_input_array(INPUT_POST, array( 'name' => FILTER_SANITIZE_STRING, 'pw' => FILTER_SANITIZE_STRING, )); if (is_null($post) || in_array(null, $post)) { header("location:login.php"); return; // missing fields (or failed filter) } // pw is the password sent from the form $pw=$_POST['passwd']; $name=$_POST['name']; if($pw == 'testpass'){ header("location:index.php"); } else { header("location:wrong.php"); } ?> Is this a secure way to ensure the form is sent to the server and executed ONLY after the input values have been sanitized? Also, the $name value i want to pass it to index.php file. I insert a code in the index.php as follow: <?php echo $name ?> But it's empty. Any idea how to resolve it?

  • What do you call the highlight as you hover over an OPTION in a SELECT, and how can I "un"highlight

    - by devils-avacado
    I'm working on dropdowns in IE6 (SELECT with OPTIONs as children). I'm experiencing the problem where, in IE6, dropdown menus are truncated to the width of the SELECT element. I used this jquery to fix it: var css_expanded = { 'width' : 'auto', 'position' : 'absolute', 'left' : '564px', 'top' : '393px' } var css_off = { 'width' : '190px', 'position' : 'relative', 'left' : '0', 'top' : '0' } if($.browser.msie) { $('#dropdown') .bind('mouseover', function() { $(this).css(css_expanded); }) .bind('click', function() { $(this).toggleClass('clicked'); }) .bind('mouseout', function() { if (!$(this).hasClass('clicked')) { $(this).css(css_off); } }) .bind('change blur focusout', function() { $(this).removeClass('clicked') .css(css_off) }); }; It works fine in IE7+8, but in IE6, if the user clicks on a SELECT and does not click any OPTION but instead clicks somewhere else on the page, outside the SELECT (blur), the SELECT still has a "highlight", the same as if they were hovering over an OPTION with my mouse (in my case, a blue color), and the width is not restored until the user clicks outside the SELECT a second time. In other browsers, blur causes every OPTION to not be highlighted. Using JS, how can I de-highlight an option after the dropdown has lost focus.

  • Why does Firefox + My code Destroys FireFox refresh

    - by acidzombie24
    I am soo angry right now. I lost hours and i dont know why this happens. Its a semi rant but i'll try to keep it short My code would not work, even after refreshing it was broken I fixed my code or so i thought because it stops working without me changing anything (you would think i am imagining this...) I somehow decide to make a new window or tab i run my code and verifies it works. I write more code and see everything is broken again I write test in a new window and see my code does work I see my code doesnt work and firebug DOES NOT HELP I notice when i create a new tab everything works I realize refreshing does not work and i MUST make a new tab for my code to work. Then i knew instantly what the problem was. I modify a display:none textbox but i set the values incorrectly. I cant see it because it is hidden. Now some of you might say its my fault because when doing a refresh all of the data may be cache. But here is the kicker. I was using POST data. I posted in between of the refresh each and everytime. Whats the point of using POST when the same data is cached and use anyways? If theres no chance for a search engine to follow a block user get link then why should i bother making anything post when security or repeat actions are not an issue? POST didnt seem to do anything.

    - by dayscott
    I wanted to write a simple chrome extension in order to substitute the following sequence of steps which i have to do very often for university: make screenshot of something edit screenshot in Paint save unnamend.png to harddrive upload unnamed.png to imageshack.us/pic-upload.de or any other website share link of image with others. I don't care which image upload service to use, i just want automize this use-case in order to save time (I already red and did a getting-started chrome extension and checked out their API, but that's it, this page: http://farter.users.sourceforge.net/blog/2010/11/20/accessing-operating-system-clipboard-in-chromium-chrome-extensions/ seemed useful, but i couldn't make it overwrite my systems clipboard - moreover i can't find a tutorial which helps me further).

When I try to initialize them only the second of the two elements appear no matter what order I put them in. Here is the code for my view. var BodyShapeView = Backbone.View.extend({ thingiview: null, scene: null, renderer: null, model: null, mouseX: 0, mouseY: 0, events:{ 'click button#front' : 'front', 'click button#diag' : 'diag', 'click button#in' : 'zoomIn', 'click button#out' : 'zoomOut', 'click button#on' : 'rotateOn', 'click button#off' : 'rotateOff', 'click button#wireframeOn' : 'wireOn', 'click button#wireframeOff' : 'wireOff', 'click button#distance' : 'dijkstra' }, initialize: function(name){ _.bindAll(this, 'render', 'animate'); scene = new THREE.Scene(); camera = new THREE.PerspectiveCamera( 15, 400 / 700, 1, 4000 ); camera.position.z = 3; scene.add( camera ); camera.position.y = -5; var ambient = new THREE.AmbientLight( 0x202020 ); scene.add( ambient ); var directionalLight = new THREE.DirectionalLight( 0xffffff, 0.75 ); directionalLight.position.set( 0, 0, 1 ); scene.add( directionalLight ); var pointLight = new THREE.PointLight( 0xffffff, 5, 29 ); pointLight.position.set( 0, -25, 10 ); scene.add( pointLight ); var loader = new THREE.OBJLoader(); loader.load( "img/originalMeanModel.obj", function ( object ) { object.children[0].geometry.computeFaceNormals(); var geometry = object.children[0].geometry; console.log(geometry); THREE.GeometryUtils.center(geometry); geometry.dynamic = true; var material = new THREE.MeshLambertMaterial({color: 0xffffff, shading: THREE.FlatShading, vertexColors: THREE.VertexColors }); mesh = new THREE.Mesh(geometry, material); model = mesh; // model = object; scene.add( model ); } ); // RENDERER renderer = new THREE.WebGLRenderer(); renderer.setSize( 400, 700 ); $(this.el).find('.obj').append( renderer.domElement ); this.animate(); }, Here is how I create the instances var morphableBody = new BodyShapeView({ el: $("#morphable-body") }); var bodyShapeView = new BodyShapeView({ el: $("#mean-body") }); Any help would be really appreciated.

  • jQuery: Need to "refresh" a widget.

    - by Legend
    I am adapting the Coverflow technique to work with a div. The coverflow function (included as a js file in the head section) is here. When I dynamically add a DIV, it doesn't show up in the coverflow. I am wondering if there is a way to add a destroy function to this js file so that whenever a new div add is added, I can call the destroy method and then reinstantiate. Any suggestions on how I should go about doing this?

  • How to override JS function from a firefox extension?

    - by BruceBerry
    Hello, I am trying to intercept calls to document.write for all pages. Setting up the interception inside the page by injecting a script like function overrideDocWrite() { alert("Override called"); document.write = function(w) { return function(s) { alert("special dom"); w.call(this, wrapString(s)); }; }(document.write); alert("Override finished"); } is easy and works, but i would like my extension to setup the interception for each document object from inside the extension. I couldn't find a way to do this. I tried to listen for the "load" event and set up the interception there but it also fails. How do I hook calls to doc.write from an extension?
