    - by Nimbuz
    jquery-1.4.2.min.js is 71.8KB Same file compressed through this tool, with gzip enabled, becomes 32.9 KB Which is better? If latter, why doesn't jQuery provide a packed file too instead of just uncompressed and min versions? Thanks

  • Weird black spots on custom Google Map with IE

    - by Domenic
    Hello. I'm getting some weird black spots with a custom map page (via the Google Maps API v2.x) I have created. (Click SERVICIOS and then the icon farthest south to generate image shown below.) The issue seems to only appear when using Internet Explorer. I'm wondering if this is a common problem and if there is a common fix? Any ideas? Thanks.

  • How to reenable event.preventDefault?

    - by Richbits
    I have a web page which I have prevented the default action on all submit buttons, however I would like to re-enable default submit action on a button how can I do this? I am currently preventing the default action using the following: $("form").bind("submit", function(e){ e.preventDefault(); }); I have successfully done this using the following: $(document).ready(function(){ $("form:not('#press')").bind("submit", function(e){ e.preventDefault(); }); But can I do this dynamically when the button is clicked?

  • JSON.Stringify data including boolean values

    - by ancdev
    What I'm trying to do is to pass JSON object to a WebAPI ajax call and mapped to a strongly typed object on the server side. String values are being posted perfectly however when it comes to boolean values, they are not being passed at all. Below is my code: var gsGasolineField = $('.gsGasoline').val(); blData = { Gasoline: gsGasolineField }; var json = JSON.stringify(blData); $.ajax({ type: "POST", url: url, data: json, contentType: "application/json", dataType: "json", statusCode: { 201 /*Created"*/: function (data) { $("#BusinessLayerDialog").dialog("close"); ClearForm("#BusinessLayerForm"); }, 400: /*Bad request - validation error*/ function (data) { $("#BusinessLayerForm").validate().form(); }, 500: function (data) { alert('err'); } }, beforeSend: setHeader }); Gasoline property is of type boolean on the server side.

    I have two arrays which contain objects in each element of the array. var array1 = [{firstName: "John", lastName: "McDonald"}, {firstName: "Sandy", lastName: "Johnson"},....,] var array2 = [{userName: "Donald"}, {userName: "John"},....,] In psuedo-code, I want to do the following: for each element in array1, is array1[i].firstName == to any of the userName's in array2. In plain english I want to look at each firstname in array1 and see if it exists at all in array2 as the value associated with the userName property.

  • Highlight DIV and dim the rest on mouseover

    - by Darren Sweeney
    I have a page full of DIVs which contain images. When I mouse over an image I can highlight it or add a shadow to accent it easily by adding class etc but is there a way to dim every other image instead. DIVs are loaded into DOM and I would like the DIV currently hovered over to retain 100% or 1 opacity and the rest of the DIVs on the page to fade to say 70% or 0.7 when one DIV is highlighted. Is this possible?

  • Is jWYSIWYG editor too buggy for production use?

    - by alex
    After reading the comments on this site: http://www.webresourcesdepot.com/jwysiwyg-jquery-inline-content-editor-plugin/ There is a bit of consensus that jWYSIWYG editor is too buggy (especially in the last few recent comments). Has anyone had experience with it in a large production site? I haven't run a huge sample of markup through it yet, but so far it has seemed to do the job fine.

  • Point data structure for a sketching application

    - by bebraw
    I am currently developing a little sketching application based on HTML5 Canvas element. There is one particular problem I haven't yet managed to find a proper solution for. The idea is that the user will be able to manipulate existing stroke data (points) quite freely. This includes pushing point data around (ie. magnet tool) and manipulating it at whim otherwise (ie. altering color). Note that the current brush engine is able to shade by taking existing stroke data in count. It's a quick and dirty solution as it just iterates the points in the current stroke and checks them against a distance rule. Now the problem is how to do this in a nice manner. It is extremely important to be able to perform efficient queries that return all points within given canvas coordinate and radius. Other features, such as space usage, should be secondary to this. I don't mind doing some extra processing between strokes while the user is not painting. Any pointers are welcome. :)

    I'm trying to add style elements to all ALL the head elements in a document, including those in an iframe. if i use var heads = document.getElementsByTagName('head'); It just returns the first head element and not the ones in the iframe. this is the complete code : var heads = document.getElementsByTagName("head"); var style = document.createElement("style"); style.type = "text/css"; style.appendChild(document.createTextNode(css)); for(var i=0;i<heads.length;i++) heads[i].appendChild(style); but this doesn't seem to work! am i doing something wrong here...?

  • I need help understanding how this jQuery filter function works, line-by-line, if possible

    - by user717236
    Here is the HTML: <div> <h3>text</h3> </div> <div> <h3>moretext</h3> </div> <div> <h3>123</h3> </div>?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Here is the JS: var rv1_wlength = $("div").filter(function() { return $(this).find("h3").filter(function () { return $(this).text() != "123"; }).length; }); var rv1_wolength = $("div").filter(function() { return $(this).find("h3").filter(function () { return $(this).text() != "123"; }); }); var rv2 = $("div").find("h3").filter(function() { return $(this).text() != "123"; }); alert(rv1_wlength.text()); // text // moretext alert(rv1_wolength.text()); // text // moretext // 123 alert(rv2.text());? // textmoretext I don't understand why the first two methods print the elements on each line, whereas the second method concatenates them. "rv2" is a jQuery object. Then, what are the first two (rv1_wlength and rv1_wolength)? Furthermore, I don't understand why the inclusion of the length property makes all the difference in filtering the elements. The second method does nothing, since it returns all the elements. The first method, with the only change being the addition of the length property, correctly filters the elements. I would very much like a line-by-line explanation. I would sincerely appreciate any feedback. Thank you.

  • Google Chrome and (cache or memory leaks).

    - by Alexey Ogarkov
    Hello All, I have a big problem with Google Chrome and its memory. My app is displaying to user several image charts and reloads them every 10s. In the interval i have code like that var image = new Image(); var src = 'myurl/image'+new Date().getTime(); image.onload = function() { document.getElementById('myimage').src = src; image.onload = image.onabort = image.onerror = null; } image.src = src; So i have no memory leaks in Firefox and IE. Here the response headers for images Server Apache-Coyote/1.1 Vary * Cache-Control no-store (// I try no-cache, must-revalidate and so on here) Content-Type image/png Content-Length 11131 Date Mon, 31 May 2010 14:00:28 GMT Vary * taken from here In about:cache page there is no my cached images. If i enable purge-memory-button for chrome (--purge-memory-button parameter) it`s not help. Images is in PNG24. So i think that the problem is not in cache. May be Google Chrome is not releasing memory for old images. Please help. Any suggestions. Thanks.

  • MVC JsonResult not working with chrome?

    - by Karsten Detmold
    i want jquery to take a JsonResult from my MVC controller but it does'nt receive any data! If I put the output into a textfile and enter its link its working so I think my jQuery is fine. Then I was testing with other browsers like chrome and I saw NOTHING. The requested page was just emtpy.. no errors. Also IE seems to have problems receiving my string.. only firefox displays the string but why? public JsonResult jsonLastRequests() { List<Request> requests = new List<Request>(); while (r.Read()) { requests.Add(new Models.Request() { ID = (int)r[0], SiteID = r[1].ToString(), Lat = r[2].ToString(), City = r[4].ToString(), CreationTime = (DateTime)r[5] }); } r.Close(); return Json(requests); } I found out that also if I want to return the JSON as string its not working! Its working with a string in all browsers now.. but jQuery is still not loading anything var url = "http://../jsonLastRequests"; var source = { datatype: "json", datafields: [ { name: 'ID' }, { name: 'SiteID' }, { name: 'Lat' }, { name: 'CreationTime' }, { name: 'City' }, ], id: 'id', url: url }; var dataAdapter = new $.jqx.dataAdapter(source, { downloadComplete: function (data, status, xhr) { }, loadComplete: function (data) { }, loadError: function (xhr, status, error) { } }); I fixed my problem by adding: access-control-allow-origin:*

  • In Node.JS, how do I return an entire object from a separate .js file?

    - by Matthew Patrick Cashatt
    Thanks for looking. I am new to Node.js and trying to figure out how to request an object from a separate file (rather than just requesting a function) but everything I try--exports,module-exports,etc--is failing. So, for example, if I have foo.js: var methods = { Foobar:{ getFoo: function(){return "foo!!";}, getBar: function(){return "bar!!";} } }; And now I want to call a function within an object of foo.js from index.js: var m = require('./Methods'); function fooMain(){ return m.Foobar.getFoo(); }; How do I do this? I have tried all sorts of combinations of exports and module-exports but they seem to only work if I call a discrete function that is not part of an object. Thanks!

  • Inconsistent Loading Times for GeoRSS Overlay Between Firefox and IE

    - by Mark Fruhling
    I have a very simple page built to display a map and overlay a line based on points in a GeoRSS XML file. Here is the publicly accessible file. http://68.178.230.189/georssimport.html Firefox is loading in about 5 secs, which is expected because there are a lot of points to map, but IE (6 & 7) is taking upwards of 45 secs to a minute. What can I do to diagnose what is going on? What is a tool that will show me what is going on? (i.e. Firebug for IE) Thanks, Mark

  • Basic Tooltip (jQuery)

    - by Nimbuz
    HTML: <a href="#" rel="tooltip">Open Tooltip</a> <div id="tooltip">Tooltip Content</div> I checked out some tooltip plugins but my requirement is a really basic tooltip that shows a hidden div on hover. All plugins either have too many advanced options that I don't require and have already styled tooltips that might be difficult to modify. I'd appreciate any help. Thanks.
