  • Google Maps: Multimarker not working

    - by HyperDevil
    Hi, I want to plot several markers on my map. Found some code on the internet, for that user it worked. The array is generated by PHP, example: var ships = [['61','10.2']['60.5','10.1']]; My Javascript: var map; function load(ships) { initialize(); createShips(ships); } function initialize() { //build the map var myLatlng = new google.maps.LatLng(63.65,10.65); var myOptions = { zoom: 9, center: myLatlng, mapTypeId: google.maps.MapTypeId.TERRAIN } var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); } function createShips(ships) { for (var i = 0; i < ships.length; i++) { new google.maps.Marker({ position: new google.maps.LatLng(ships[i][0], ships[i][1]), map: map, title: ships[i][0] }); } } My html function to start the map is: body onload="load()" The map seems to appear, but no markers :(

  • Cascading Dropdown List

    - by user333831
    I am working on a web app and trying to code a form with two dropdown lists. The list in the second dropdown will be dependent on the selection from the first one. The task itself isn’t too complicated except that once the first selection is made, I need to make a database call to pull the data for the second dropdown. This is where I am having difficulty. Both lists are in fact populated from a database. I am working on this in a python script and have been trying to do this w/ an onChange javascript function. The web app is built in Zope and page templates may be an option along w/ the python scripts.

  • "Parsing" I think is the word.

    - by Anonymous the Great
    I'm working on a little parsing thing to color objects. For an example, you could type red:Hi!: and "Hi!" would be red. This is my not working code: <script type="text/javascript"> function post() { var preview = document.getElementById("preview"); var submit = document.getElementById("post"); var text = submit.value; <?php str_replace("red:*:",'<i class="red">*</i>',text); ?> preview.value = text; } </script>

  • Is there a way to send text to an aspcontrol via jquery

    - by Garrith Graham
    Is there a way to send data to an aspcontrol say a label called label1? Via jquery? I know jquery only likes html but is there a way to just send the raw text to an asp control using a similar method below: <script type="text/javascript"> $(document).ready(function () { var label = $("#<%= testLabel.ClientID %>"); var div = $("<div></div>").html("content").attr('id', 'test'); var serializer = new XMLSerializer(); label.text(serializer.serializeToString(div)); }); </script>

  • How to show a page after a specific time period?

    - by Mahfuz
    I want to build an online quiz test site. Suppose, exam will start at 10:00 am and a student login to give exam at 9:45 am. Whenever the student clicks 'Take Exam' button, he/she cannot not get access to the question paper because the exam time is 10:00 am and there are still 15 minutes before the exam start. Now I want to put some Javascript or PHP code that will prohibit the students to give exam earlier and if a students come early, it will show a stopwatch which display the remaining time before exam time and when the current time is equal to exam time then he/she will be directly redirected to the question paper page.

  • Regular expression replacing only if contained withing a regular expression match?

    - by Tower
    Hi, I have the following: [list] [*] test [*] test [*] test [/list] and I would like to create a regular expression that turns that into: <ul> <li>test</li> <li>test</li> <li>test</li> </ul> I know regex enough to replace simple tags, but in this case I need to replace li tags only if they are contained inside ul. Is there a way to check that before replacing? I am using JavaScript if that matters.

  • Most effective server side programming language for web development?

    - by ihaveitnow
    This is more a question of pros/cons between PHP and JAVA. Iv been doing research, and iv narrowed it down to those two. And in consideration, id like to go into mobile app dev...So thats +1 for Java. Time taken to learn the language is not an issue...Just would like to know which is the most profitable at the end of all the training. And on a slight note. Can Javascript work with Java? And what is the real advantage of that?

  • TypeError: Cannot find function 1.0.

    - by Newtopian
    Hi, I have a script and I'm almost done but I get this error and frankly I have no idea what is wrong here. I'm rather new to Javascript so I suspect I did something wrong in the syntax somewhere. Here is an extract from the script containing the offending line : var gc = 0; var seg; var segCount = 0; var groupCount = 0; var groupLevel = 0; var segments = new Array(); var sk = ""; for(gc = 0; gc = groupDelimiters.length) break; if(seg.name() == groupDelimiters[gc]) { //ok we start another group grKeys.startNewGroup(groupLevel, groupCriterionExtractors[groupLevel](segCount), groupCount); groupLevel = gc + 1; //This line is flagged with the error in the title groupCount++; } } ideas, pointers, any help would be appreciated.

  • Intercept close Popup from Parent Page

    - by sangi
    Hi all, I have a question. In an html page, I have javascript code that allows me to open and close a popup window by clicking on a link displayed in the link, so the text displayed in the link changes to the state of the popup window (open-closed). With a variable true / false I manage the opening and closing of the popup window to click on a link whose text is aligned "opened popup" / "closed popup". The next step is to make this same change in state (true / false, "opened popup" / "close popup") directly by closing the popup window. The idea is to not have to refresh the page. Is this possible? Thank you and best regards

  • innerHTML yielding undefined, but correct data is visible

    - by Mike Dyer
    var Model,node; document.getElementById('sedans').innerHTML=''; var thismodelabbr,prevmodelabbr; for(var j=0; j<xmlDoc.getElementsByTagName('data').length; j++){ node = xmlDoc.getElementsByTagName('data')[j]; thismodelabbr=node.getAttribute('model'); if(prevmodelabbr!=thismodelabbr){ Model+='<a href="">'+ node.getAttribute('model')+'</a>'; } prevmodelabbr=thismodelabbr; document.getElementById('sedans').innerHTML=Model; } The above javascript snippet is working correctly and as needed, but I'm getting an "Undefined" response before the entry is displayed within its respective page. I'm assuming it has to do with the .innerHTML call. Any insight would be deeply appreciated.

  • How to efficiently deal with a large amount of HTML5 canvas pixel data over websockets

    - by user730569
    Using imageData = context.getImageData(0, 0, width, height); JSON.stringify(imageData.data); I grab the pixel data, convert it to a string, and then send it over the wire via websockets. However, this string can be pretty large, depending on the size of the canvas object. I tried using the compression technique found here: JavaScript implementation of Gzip but socket.io throws the error Websocket message contains invalid character(s). Is there an effective way to compress this data so that it can be sent over websockets?

  • Handling JSON and HTML templates in jQuery

    - by Toby Hede
    I have an ajax-enabled site that presents a lot of dynamic content by interpolating JSON values with HTML. This all works fine. BUT it means I have significant amounts of HTML all through my JavaScript. For example: var template = "<div>Foo: {bar}</div><div>Blah: {vtha}</div>"; template.interpolate({bar:"bar",blah:"vtha"}); I have cut this down a fair bit - some of my dynamic elements have quite a lot of HTML and a lot going on. I am using jQuery and I am building on Rails, so if there is something smart in either framework, that would be great. For reference, the String interpolation function used above is: String.prototype.interpolate = function (o) { return this.replace(/{([^{}]*)}/g, function (a, b) { var r = o[b]; return typeof r === 'string' || typeof r === 'number' ? r : a; } ); };

  • Dynamic Dropdown menu through php

    - by Code_Ed_Student
    I visited a website a few weeks ago and came across a dynamic drop down menu. I came across a functionality that I am now trying to replicate but do not know how. In the dropdown you picked the desired number of cars and then it reiterated input fields according to the number of cars chosen. I believe this was done through javascript and a loop was involved. Is there a term for this action or way to display things? Also an example of how to accomplish something similar would help?

  • jQuery way to handle select lists, radio buttons and checkboxes

    - by Álvaro G. Vicario
    When I handle HTML form elements with jQuery, I always end up with an ugly mix of jQuery syntax and plain JavaScript like, e.g.: function doStuff($combo){ if( $combo.get(0).options[$combo.get(0).selectedIndex].value=="" ){ var txt = ""; }else{ var txt = $combo.get(0).options[$combo.get(0).selectedIndex].text; } var $description = $combo.closest("div.item").find("input[name$=\[description\]]"); $description.val(txt); } Are there standard jQuery methods to handle typical operations on elements like <select>, <input type="radio"> and <input type="checkbox">? With typical, I mean stuff like reading the value of the selected radio button in a group or replacing elements in a selection list. I haven't found them in the documentation but I admit that method overloading can make doc browser kind of tricky.

  • Are Ext JS files necessary in a working site?

    - by songdogtech
    I've inherited a high-traffic site that loads some Ext javascript files and I'm trying to trim some bandwidth usage. Are Ext libraries necessary for development only or are they required for the finished site (I've never used Ext.) The site loads ext-base.js, ext-all-debug.js, expander.js, exteditor.js. It appears that expander.js and exteditor.js have some site specific code, so they should stay? But what about ext-base.js and ext-all-debug.js? Am I reading this correctly - are base and debugging libraries necessary for a live site?

  • Toggle DIV and SPAN text onclick

    - by philipryoung
    I have been trying to mimic this website http://www.designrattan.co.uk/daybed/apple for a while now. I need to make a page where the customer can click "View 360" and then it changes the DIV to show the product 360 (for which I already have the code for). I also need to make it so that when it is clicked the span text then changes to "Back to Image" I have tried many times and have failed to get the Javascript code and HTML to work well together. My efforts can be seen here: http://designliving.tk/winchester-rattan-garden-round-table-set As you can see it is a complete fail as it doesn't change the DIV it just displays a new one. Also when you click the button it then changes to text instead of a new button. If anyone can help me here I would be massively appreciative and if I need to pay you for your efforts then please contact me on [email protected]

  • jQuery selector loads images from server

    - by Guillaume
    Hi! here is the code: <script type="text/javascript"> var ajax_data = '<ul id="b-cmu-rgt-list-videos"><li><a href="{video.url}" '+ 'title="{video.title.strip}"><img src="{video.image}" '+ 'alt="{video.title.strip}" /><span>{video.title}</span></a></li></ul>'; var my_img = $(ajax_data).find('img'); </script>` ajax_data is data from a JS template engine where I need to get some part of it. The problem is that jQuery does a GET on the img src={video.image}: GET /test/%7Bvideo.image%7D HTTP/1.1 (on Firefox Live HTTP headers). This GET generates a 404 from the server. Any clues on how to solve this? Thanks a lot :)

  • How to get selenium to click on an object other than by ID

    - by Zombies
    So here is a little challenge. I have an image. It has 2 attributes: a random ID - not helpful an image url - but it is a button, and other buttons use the same image url, not helpful a CSS class - also used by too many other things to be helpful a style - neither helpful nor unique This image is however inside of an anchor tag, but the anchor tab isn't to a page, it just runs some javascript. Bellow is the html in question: <a id="template:j_id__ctru168pc2" title="Click for the Manual Class LOV" class="xei" style="text-decoration: none;" onclick="return false;" href="#"> <img id="template:j_id__ctru169pc2" class="xgs" style="border: 0pt none;" src="images/lov_ena.png"> </a> How can I click this image without using the ID?

  • JQuery Accordion - bottom-up in stead of top-down

    - by Tim Geerts
    Hi there, I have a question about the accordion plugin for jQuery. Basically, I've got it to work on my site nicely, there's just one thing that I'd have liked it to do and that is bottom-up opening in stead of top-down. What I mean by that is that my 3 buttons just stand in the vertical menu (div) in the bottom. And when you click it, they'll slide open but upwards, not downwards. Is there a way to achieve this easily? I've gone through the documentation, but can't find any native support for it, so I was wondering if it was possible to do it in the javascript of the plugin itself. Thanks in advance.

  • Simple graphics API with transparency, polygons, reading image pixels?

    - by M. Elkstein
    I need a simple graphics library that supports the following functionality: Ability to draw polygons (not just rectangles!) with RGBA colors (i.e., partially transparent), Ability to load bitmap images, Ability to read current color of pixel in a given coordinate. Ideally using JavaScript or Python. Seems like HTML 5 Canvas can handle #2 and #3 but not #1, whereas SVG can handle #1 and #2 but not #3. Am I missing something (about either of these two)? Or are there other alternatives?
