  • jQuery drawing and modifying lines and positions

    - by Chris
    I want to allow people to select a feature region on an image using jQuery. This should work similarly to the Facebook tagger except once someone "tags" an area of the image an ellipse should appear with the ability for the user to rotate and scale it. How can I achieve this using jQuery?

  • How to properly pass address to google geocoding service

    - by clinisbut
    I'm getting some problems trying Google Geocoding service when using special characters like "º" or letters with accents. Whenever I try something like: "barcelona, nº 10" I get 0 results. But trying: "barcelona n 10" I get results... I suspect is something related with encoding. I tried this: geocoder.geocode({'address': encodeURI( $('#direction').val() )}, function(){} ); But didn't help. Any Idea?

  • Are support for Object.hasOwnProperty and Function.call reliably mutual?

    - by kennebec
    Can anyone tell me if there are any clients (browsers) that define a functioning Object.prototype.hasOwnProperty that do NOT define a Function.prototype.call? That is, must I use belt and suspenders to qualify clients for a certain level of scripting, or will hasOwnProperty do for both? if(Object.hasOwnProperty && Function.call){ // add script } Is support for either of these properties a reliable subset of support for the other?

  • Iframe auto-height not working when page changes in IE

    - by DisgruntledGoat
    I have an iframe in a page, with the following auto-height script. function autoHeight(e) { if ( e.contentDocument ) { e.height = e.contentDocument.body.offsetHeight + 35; } else { e.height = e.contentWindow.document.body.scrollHeight + 35; } } document.domain = "totalstudents.co.uk"; var ifr = document.getElementById('housingdata'); ifr.onload = function() { autoHeight(ifr); } The iframe resizes fine when the outer page is loaded, but when I go to a new page in the iframe, scrollbars appear and the page does not get resized in Internet Explorer. In other browsers the iframe gets resized, because the onload event fires each time. I'm using IE8 but the outer page is setting it to IE7 compatibility mode. Is there a workaround for IE?

    - by user348250
    Hello! I'm triying to add an easing function to this code. So I replaced "swing" with "easeInOutQuint" (for example) but it's not working. I'm using jquery 1.4.2 and jquery easing 1.3 downloaded from here (http://gsgd.co.uk/sandbox/jquery/easing/) Any help will be greatly appreciated! Thank you! $(window).load(function() { $('.trigger').click(function() { $('.panel').animate({ width: ['toggle', 'swing'], height: ['toggle', 'swing'], opacity: 'toggle' }, 190, 'linear', function() { }); });

  • jQuery reports incorrect element height in Firefox iframe

    - by Augustus
    Here a short test to demonstrate my problem. I have a page that loads an iframe: <html> <head> <title></title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js"></script> </head> <body> <iframe id="iframe" src="box.html" style="width: 100px; height: 100px"></iframe> <script> $('#iframe').bind('load', function () { var div = $(this).contents().find('div'); alert(div.height()); alert(div.innerHeight()); alert(div.outerHeight()); alert(div.outerHeight(true)); }); </script> </body> </html> The iframe (box.html) contains a single styled div: <html> <head> <title></title> <style> div { height: 50px; width: 50px; margin: 5px; padding: 5px; border: 2px solid #00f; background-color: #f00; } </style> </head> <body> <div></div> </body> </html> The four alerts should return 50, 60, 64 and 74, respectively. This works as expected in Safari and Chrome. In FF 3.5.1, they all return 64. This is wrong. Does anyone know how I can force FF/jQuery to return the correct values?

  • Callback for When jqGrid Finishes Reloading?

    - by James
    Hi, I am using the jqGrid plug-in and at one point I need to refresh the grid and set the selected row to match the record that I am showing in detail on another section of the page. I have the following code but it does not work: $("#AllActions").trigger("reloadGrid").setSelection(selectedRow); The selectedRow parameter comes from an event handler that gets called when the data is changed and the grid needs to be updated. I'm pretty sure that the problem is that the grid is not loaded when the selection is being set, because if I put a call to alert() between the calls to trigger() and setSelection(), it works. I would be grateful for any advice. [Edit]Looks like http://stackoverflow.com/questions/2529581/jqgrids-setselect-does-not-work-after-reloadgrid is related but did not get resolved.[/Edit]

  • Regular Expressions - Match all alphanumeric characters except individual numbers

    - by imaginonic
    I would like to create a RegEx to match only english alphanumeric characters but ignore (or discard) isolated numbers in Ruby (and if possible in JS too). Examples: 1) I would like the following to be matched: 4chan 9gag test91323432 asf5asdfaf35edfdfad afafaffe But not: 92342424 343424 34432 and so on.. The above is exactly what I would want. 2) However, I would be really thankful if someone could also include French letters like: é ë ê (These are just few examples of many) 1) is my priority, it's totally okay if 2) is impossible or difficult to implement. Sorry, my regex skills aren't that great (hence this question!) Thank you.

    For example: <input type="text" name="test" onChange="document.formname.test.value=.document.formname.test.value.replace('something','something else')" /> The replace function works but it loses focus on every change How do you make it not lose focus?

  • Regex, replace path to resource, modify resource name

    - by jerome
    Hi all, I'd like to use a JS regex to take a string such as the following: 'http://www.somedomain.com/some_directory/some_other_directory/some_image.jpg' And turn it into this: 'http://www.some_other_domain.com/another_directory/yet_another_directory/size1_some_image.jpg' Any hints? Additionally, any pointers for books or other resources that give a gentle introduction to mastering regexes in JS and other languages?

  • Pre-formatting text to prevent reflowing

    - by mattjn
    I've written a fairly simple script that will take elements (in this case, <p> elements are the main concern) and type their contents out like a typewriter, one by one. The problem is that as it types, when it reaches the edge of the container mid-word, it reflows the text and jumps to the next line (like word wrap in any text editor). This is, of course, expected behavior; however, I would like to pre-format the text so that this does not happen. I figure that inserting <br> before the word that will wrap would be the best solution, but I'm not quite sure what the best way to go about doing that is that supports all font sizes and container widths, while also keeping any HTML tags intact. I figure something involving a hidden <span> element, adding text to it gradually and checking its width against the container width might be on the right track, but I'm not quite sure how to actually put this together. Any help or suggestions on better methods would be appreciated.

  • Finding the URL of an XMLHttpRequest

    - by hawkettc
    Hi, I've got some code that does an ajax request using jQuery, and handles success and error conditions. On an error, I want to find out what the URL I called was, so I can log it. This information appears to be contained in the XMLHttpRequest.channel, but firefox is complaining about accessing this - Permission denied for <http://localhost:8081> to get property XMLHttpRequest.channel Any ideas how I can determine the URL associated with an XMLHttpRequest? What's the security issue getting hold of this information? Cheers, Colin

  • How can I restore the order of an (incomplete) select list to its original order?

    - by Rob
    I have two Select lists, between which you can move selected options. You can also move options up and down in the right list. When I move options back over to the left list, I would like them to retain their original position in the list order, even if the list is missing some original options. This is solely for the purpose of making the list more convenient for the user. I am currently defining an array with the original Select list onload. What would be the best way to implement this?

  • select2: "text is undefined" when getting json using ajax

    - by user3046715
    I'm having an issue when getting json results back to select2. My json does not return a result that has a "text" field so need to format the result so that select2 accepts "Name". This code works if the text field in the json is set to "text" but in this case, I cannot change the formatting of the json result (code outside my control). $("#e1").select2({ formatNoMatches: function(term) {return term +" does not match any items." }, ajax: { // instead of writing the function to execute the request we use Select2's convenient helper url: "localhost:1111/Items.json", dataType: 'jsonp', cache: true, quietMillis: 200, data: function (term, page) { return { q: term, // search term p: page, s: 15 }; }, results: function (data, page) { // parse the results into the format expected by Select2. var numPages = Math.ceil(data.total / 15); return {results: data.Data, numPages: numPages}; } } }); I have looked into the documentation and found some statements you can put into the results such as text: 'Name', but I am still getting "text is undefined". Thanks for any help.

  • A more effecient millisecond conversion method?

    - by cube
    I am currently using this method to convert milliseconds to min:sec:1/10sec. However it does not seem to be efficient at all. Would anyone know of a faster more efficient and optimized way of accomplishing the same. mills.prototype.formatTime = function(time) { var elapsedTime = (time * 1000); //Minutes var elapsedM = (elapsedTime/60000)|0; var remaining = elapsedTime - (elapsedM * 60000); //add a leading zero if it's a single digit number if (elapsedM < 10) { elapsedM = "0"+elapsedM; } //Seconds var elapsedS = ((remaining/1000)|0); remaining -= (elapsedS*1000); ////add leading zero if (elapsedS<10) { elapsedS = "0"+elapsedS; } //Hundredths var elapsedFractions = ((remaining/10)|0); if (elapsedFractions < 10) { elapsedFractions = "0"+elapsedFractions; } //display results nicely var time_data = elapsedM+":"+elapsedS+":"+elapsedFractions; //return time_data; return[time_data,elapsedM,elapsedS,elapsedFractions] };
