  • How do I nested options for plugins in jQuery

    - by Oscar Godson
    I know how to do plugins, but how do I do nested options like: var defaults = { spacing:10, shorten_to:50, from_start:0, from_end:2, classes: { test:'testing' } }; i know that isn't right, i just dont know how to write the proper syntax when I want to do something like this: $('#breadcrumbs').breadcrumbs({classes{test:'new_example'},spacing:12}) other suggestions are welcome, im in need of the ability to custom class names and there are 7, so rather than making something like test_class, example_class, etc id like it cleaner and neater like the example above.

  • Changing a Variable Out of Scope?

    - by Matrym
    Is there any way to change a variable while out of scope? I know in general, you cannot, but I'm wondering if there are any tricks or overrides. For example, is there any way to make the following work: function blah(){ var a = 1 } a = 2; alert(blah());

  • transition of x-axis results in overflow

    - by peter
    First of all, no: this question is not about the (yet) ugly transition of the lines (I might open another one for that, though..). I'm displaying data in line charts and the user can select the time horizon. The x-axis then correspondingly transitions so as to fit to the changed time horizon. In attached image, e.g., the time horizon was 1 week and then I switched to 4 weeks. The number of ticks on the x-axis increases from 7 to 28, correspondingly. Question: How can I prevent the x-axis animation to display outside the svg container? As you can see, the additional dates fly in from the left and they are being animated far far outside the container. Any ideas? Right now, the transition works probably in the most simple way it could: // format for x-axis var xAxis = d3.svg.axis() .scale(x) .orient("bottom") .tickFormat(d3.time.format("%d.%m")) .ticks(d3.time.days, 1) .tickSubdivide(0); // Update x-axis svg.select(".x") .transition() .duration(500) .call(xAxis);

  • getting started with Google Closure if you don't care about minifying/compiling?

    - by Tim
    If you don't care about minifying your code, is there a way to get started using the Google Closure library without having to set up a subversion client and use the compiler? The Notepad sample program on Google's website refers to <script src="closure-library/base.js" > </script > Can you simply download closure-library/base.js somewhere and start playing with the UI examples? The Closure Lite quick-start version doesn't appear to include goog.ui

  • Change default markers for directions on google maps

    - by Elaine Marley
    I'm a complete noob with google maps api and I started with a given script that I'm editing to what I need to do. In this case I have a map with some points in it that come from a database. They are like this (after I get the lat/lng from the database): var route1 = 'from: 37.496764,-5.913379 to: 37.392587,-6.00023'; var route2 = 'from: 37.392587,-6.00023 to: 37.376964,-5.990838'; routes = [route1, route2]; Then my script does the following: for(var j = 0; j < routes.length; j++) { callGDirections(j); document.getElementById("dbg").innerHTML += "called "+j+"<br>"; } And then the directions: function callGDirections(num) { directionsArray[num] = new GDirections(); GEvent.addListener(directionsArray[num], "load", function() { document.getElementById("dbg").innerHTML += "loaded "+num+"<br>"; var polyline = directionsArray[num].getPolyline(); polyline.setStrokeStyle({color:colors[num],weight:3,opacity: 0.7}); map.addOverlay(polyline); bounds.extend(polyline.getBounds().getSouthWest()); bounds.extend(polyline.getBounds().getNorthEast()); map.setCenter(bounds.getCenter(),map.getBoundsZoomLevel(bounds)); }); // === catch Directions errors === GEvent.addListener(directionsArray[num], "error", function() { var code = directionsArray[num].getStatus().code; var reason="Code "+code; if (reasons[code]) { reason = reasons[code] } alert("Failed to obtain directions, "+reason); }); directionsArray[num].load(routes[num], {getPolyline:true}); } The thing is, I want to change the A and B markers that I get from google on the map to the ones for each of the points that I'm using (each has it's particular icon in the database) but I don't know how to do this. Furthermore, what would be fantastic but I'm clueless if it's even possible is the following: when I get the directions I get something like this: (a) Street A directions (b) Street B And I want (a) Name of first point directions (b) Name of second point (also from database) I understand that my knowledge of the subject is very lacking and the question might be a bit vague, but I would appreciate any tip pointing me in the right direction. EDIT: Ok, I learned a lot from the google api with this problem but I'm still far from what I need. I learned how to hide the default markers doing this: // Hide the route markers when signaled. GEvent.addListener(directionsArray[num], "addoverlay", hideDirMarkers); // Not using the directions markers so hide them. function hideDirMarkers(){ var numMarkers = directionsArray[num].getNumGeocodes() for (var i = 0; i < numMarkers; i++) { var marker = directionsArray[num].getMarker(i); if (marker != null) marker.hide(); else alert("Marker is null"); } } And now when I create new markers doing this: var point = new GLatLng(lat,lng); var marker = createMarker(point,html); map.addOverlay(marker); They appear but they are not clickable (the popup with the html won't show)

  • How to handle empty return from getJSON

    - by Gee
    Alright so I have a php script which gets results from a DB, and to get those results I'm using a jQuery script to pull the results via getJSON. It works perfectly but now I want to do something if the php script returns no results (empty). I tried: $.getJSON('path/to/script'), {parameter:parameter}, function(data){ if (data) { alert('Result'); } else { alert('Empty); } }); But it's no good. I've tried different things like if (data.length) but still nothing. I've noticed that if there is no returned data the callback will never fire at all. So if that's the case, how do I handle a empty return?

  • How can I find out if an data- attribute is set to an empty value?

    - by Stephan Wagner
    Is there a way to find out if an data- attribute is set to an empty value or if it is not set at all? See this fiddle example (Check the console when clicking on the elements): http://jsfiddle.net/StephanWagner/yy8qvwfp/ <div onclick="console.log($(this).attr('data-test'))">undefined</div> <div data-test="" onclick="console.log($(this).attr('data-test'))">empty</div> <!-- this one will also return an empty value --> <div data-test onclick="console.log($(this).attr('data-test'))">null</div> <div data-test="value" onclick="console.log($(this).attr('data-test'))">value</div> Im having the issue with the third example. I need to know if the attribute actually is set to an empty value or if it is not set at all. Is that actually possible? EDIT: The reason I'm asking is that I'm updating content with the attributes value, so data-test="" should update the content to an empty value, but data-test should do nothing at all

  • How to customize /#/ in Jquery address plugin

    - by Lauren
    Hi, I'm using the Jquery plugin Address to achieve deep linking. The generated urls come out in the format www.example.com/#/tab/image, but what I need is www.example.com/#tab/image. The plugin seems to automatically generate the /#/ part. I wonder does anyone know how to do this? Or even if it's possible? I would greatly appreciate any help. Thanks in advance

  • jQuery: Sort div's according to content of different sub divs

    - by rayne
    I'm trying to create a somewhat complex sorting feature which neither uses divs nor lists. Unfortunately two hours of googling didn't help me. Here is the basic setup of my HTML: <div id="all_elements"> <!-- one element --> <div class="element"> <div class="wrapper"> <a href="/" title="links"> <img src="/img/image.jpg" border="0" alt="image" class="image" /></a> <div class="details"> <h3><a href="/" title="title">Name (Sort Argument 1)</a></h3> <div class="title"><a href="/" title="title">Title (Sort Argument 2)</a></div> <div class="year">2010 (Sort Argumentt 3)</div> <div class="country">Great Britain (Sort Argument 4)</div> </div><!-- details --> </div><!-- wrapper --> </div><!-- element --> </div> <!--all_elements--> The setup is a bit complex, but basically .element is the element that needs to be sorted alphabetically according to either the contents of h3, div.title, div.year or div.country. So the user will be able to view the contents of the site either sorted by name, by year, by country or by title. I have this jQuery snippet from a website, but all my attempts on trying to tell it to use the contents of e.g. h3 to sort have failed. Right now it sorts pretty much randomly. jQuery.fn.sort = function() { return this.pushStack([].sort.apply(this, arguments), []); }; function sortAscending(a, b) { return a.innerHTML > b.innerHTML ? 1 : -1; }; function sortDescending(a, b) { return a.innerHTML < b.innerHTML ? 1 : -1; }; $(document).ready(function() { $("#sort").toggle( function() { $('#all_elements .element').sort(sortDescending).appendTo('#all_elements'); $(this).text("Sort Asc"); }, function() { $('#all_elements .element').sort(sortAscending).appendTo('#all_elements'); $(this).text("Sort Desc"); }); }); How can I customize the function to sort the contents of my h3 or divs?

  • After dynamically changing a form submit function causes old function to get called once then new fu

    - by cnobile
    I am setting the submit function on a form with jQuery then later in the process I reset the function to something else. What happens is the original function gets called again then the new function when only the new function should have been called. I am sending the requests with AJAX. The first one validated the values on the server then asks if you want to continue. Clicking the submit again should only call the changed function but for some reason both get called simultaneously with a single click. What is happening here? Could jQuery be delaying the the setting of the 2nd function on the form submit?

  • How to stop toggle event from being fired multiple times on mouseenter/mouseleave?

    - by Clean
    Hi, I'm using jQuery to toggle the visibility of a using the jQuery toggle method. The toggle is fired on the mouseenter and mouseleave event, thus creating the effect of the div to fold out on mouseenter and fold in on mouseleave. Problem is, if the user drags the mouse over the a few times and then leaves the , the div will toggle in and out several times. This can happen if the user accidentally moves around the mouse pointer in the are. Do anyone have any idea on how I can avoid this behavior? Thanx!

  • Problems with jquery selector

    - by Gandalf StormCrow
    I have a trouble with selecting element attributes with jquery here is my HTML: <a class="myselector" rel="I need this value"></a> <div class="someClass" id="someID"> ...bunch of elements/content <input type="button" name="myInput" id="inputID" title="myInput Title" /> ...bunch of elements/content </div> ...bunch of elements/content Here I'm trying to get the rel value of myselector here is how I tried but its not working : $('#inputID').live('click',function(){ console.log($(this).closest('a.myselector').attr('rel')); }); Also tried this since all is wrapped in wrapper div : $('#inputID').live('click',function(){ console.log($(this).parent('div.wrapper').find('a.myselector').attr('rel')); }); I get undefined value in firebug in both cases, I use live because div#someID is loaded in the document its not there when page first loads. Any advice, how can I get my selector rel value?

  • jQuery plugin options: required, optional, inaccessible

    - by Trevor Hartman
    I'm curious how to specify options to a jQuery plugin in a way that some are required, some are optionally overridden, and some can't be touched. I started off with the usual: jQuery.fn.plugin = function (options){ var defaults = { username: "", posts:10, api: "http://myapi.com" } var settings = jQuery.extend({}, defaults, options); } Let's say I want username to be required, posts is optional (defaults to 10) and you (you being the user of the plugin) can't change api, even if they try. Ideally, they'd all still be in the same data structure instead of being split into separate objects. Ideas?
