  • F# Higher-order property accessors

    - by Nathan Sanders
    I just upgraded my prototyping tuple to a record. Someday it may become a real class. In the meantime, I want to translate code like this: type Example = int * int let examples = [(1,2); (3,4); (5,6)] let field1s = Seq.map (fst >> printfn "%d") examples to this: type Example = { Field1 : int Field2 : int Description : string } let examples = [{Field1 = 1; Field2 = 2; Description = "foo"} {Field1 = 3; Field2 = 4; Description = "bar"} {Field1 = 5; Field2 = 6; Description = "baz"}] let field1s = Seq.map Description examples The problem is that I expected to get a function Description : Example -> string when I declared the Example record, but I don't. I've poked around a little and tried properties on classes, but that doesn't work either. Am I just missing something in the documentation or will I have to write higher-order accessors manually? (That's the workaround I'm using now.)

  • Print <div id=printarea></div> only?

    - by noesgard
    How do I print the indicated div (without manually disabling all other content on the page)? I want to avoid a new preview dialog, so crating a new window with this content is not useful... The page contains a couple of tables, one of them contains the div I want to print - the table is styled with visual styles for the web, that should not be shown in print....

  • Minifying CSS, JS, and HTML - together

    - by Radu
    Minifying JS and CSS is quite common. The benefits of minifying JS are much greater that those seen with CSS because with CSS you can't rename elements - and same goes for HTML. But what if all 3 were minified together so that the benefits of using shorter names can be brought to CSS and HTML? That is, instead of minifying without any regard to the relationships between the 3, these could be preserved and made simpler. I imagine that the implementation could be quite difficult but if it were possible, do you think it would provide a significant advantage over traditional minification?

  • Simple Modal with Autocomplete in ASP.NET

    - by DanielJaymes
    Hello, I am quite new to this so any help is very much appreciated. I am generating a modal pop using Simple Modal, this works ok. I now want to add jquery autocomplete to the element txtEmail. When I run the page outside of Simple Modal I can use Autocomplete, however when the page is loaded through Simple Modal it does not work. I have checked to ensure the element is loaded, and it is allowing me to change the text color, but I can not add autocomplete to it. The code is /** * @author Daniel */ jQuery(function($) { $("input.ema, a.ema").click(function(e) { e.preventDefault(); $("#osx-modal-content").modal({ appendTo: 'form', overlayId: 'osx-overlay', containerId: 'osx-container', closeHTML: '<div class="close"><a href="#" class="simplemodal-close">X</a></div>', minHeight: 80, opacity: 65, position: ['0', ], overlayClose: true, onOpen: OSX.open, onClose: OSX.close, onShow: OSX.show }); }); var OSX = { container: null, open: function(d) { var self = this; $.ajax({ url: "/Message/UserMessage/", type: 'GET', dataType: 'html', // <-- to expect an html response success: function(result) { var data = "Core Selectors Attributes Traversing Manipulation CSS Events Effects Ajax Utilities".split(" "); $('div#osx-modal-data').html(result).find("#txtEmail").css('color', '#c00'); if ($('div#osx-modal-data').find("#txtEmail").length) { // implies *not* zero $('div#osx-modal-data').find("#txtEmail").autocomplete(data); alert('We found img elements on the page using "img"'); } else { alert('No txtEmail elements found'); } } }); self.container = d.container[0]; d.overlay.fadeIn('slow', function() { $("#osx-modal-content", self.container).show(); $('div#osx-modal-title').html("Send Email"); var title = $("#osx-modal-title", self.container); title.show(); d.container.slideDown('slow', function() { setTimeout(function() { var h = $("#osx-modal-data", self.container).height() + title.height() + 20; // padding d.container.animate({ height: h }, 200, function() { $("div.close", self.container).show(); $("#osx-modal-data", self.container).show(); }); }, 300); }); }) }, close: function(d) { var self = this; d.container.animate({ top: "-" + (d.container.height() + 20) }, 500, function() { self.close(); // or $.modal.close(); }); }, show: function(d) { // $('div#osx-modal-data').find("#txtEmail").css('color', '#ccc') } }; });

  • Graceful Degradation with JSON.Parse

    - by Steve
    If a browser doesn't support JSON.parse, would it make sense to include json.js and call parseJSON in lieu? So the code would looks something like: var z; if (JSON.parse) z = JSON.parse(yada); else z = JSON.parseJSON(yada);

  • cannot convert to object

    - by Dazz
    if i execute the following code i get a cannot convert to object error; Uncaught exception: TypeError: Cannot convert 'validation.messages.field' to object $.fn.validate = function(validation) { $.each(validation.rules, function(field, fieldRules){ $.each(fieldRules, function(rule, ruleValue){ var fieldValue = $('[name=' + field + ']').val(); if (eval(rule + '(fieldValue, ruleValue)') == false){ alert(validation.rules.field.rule); return false; }else{ return true; }; }); }); } the problem is the alert(validation.messages.field.rule); 'field' = 'persoon_voornaam' and 'rule' = 'required' and validation.messages.persoon_voornaam.required works just fine. What am i doing wrong? validation is a JSON that look like this: { rules: { persoon_voornaam: { required: true, minlength: 5, }, postcode_bestemming: { required: true, minlength: 7, }, }, messages: { persoon_voornaam: { required: 'Dit veld is verplicht', minlengt: 'Dit veld moet minstens 5 lang zijn', }, } }

  • POST data disapearing on large file upload

    - by DfKimera
    I'm having issues with a file uploading utility in my PHP application. When sending large files (9MB+) over the form, I get a very odd behaviour: the POST data I've included in the form dissapears, including the file information. I've already increased all PHP limits I could (time limit, max input time, post max size, memory limit and upload max filesize) and I still can't get the proper behaviour. I've tried replacing the regular HTTP forms with a Flash-based solution (SWFUpload, www.swfupload.org), still the same behaviour. I've tried multiple files of similar sizes and its definitely not a particular file issue. I've debugged the POST vars sent using Firebug, and the correct variables are still there in the header, together with the file. What could be going on here?

  • Selecting a div with same ID as the rel attribute of clicked link

    - by Chris
    Hi there, This is a two-part question. I'm using jQuery for a project and wanting to click a link and toggle the class name "highlight" to that link and also to the div with the same id as the rel attribute of the link. I then want to be able to link to the next div without the classname of "highlight". Here's the HTML for it: <ul> <li><a href="#" rel="panel1">Item 1</a></li> <li><a href="#" rel="panel2">Item 2</a></li> <li><a href="#" rel="panel3">Item 3</a></li> </ul> <a href="">go to next div without class of highlight</a> <div id="panel1">some text</div> <div id="panel2">some text</div> <div id="panel3">some text</div> Can anyone help with jQuery side of things? Many thanks in advance!

  • Arrays not matching correctly

    - by Nick Gibson
    userAnswer[] holds the string of the answer the user types in and is comparing it to answers[] to see if they match up and then spits out correct or wrong. j is equal to the question number. So if j was question 6, answers[j] should refer to answers[6] right? Then userAnswer[6] should compare to answers[6] and match if its correct. But its giving me wrong answers and displaying the answer I typed as correct. int abc, loopCount = 100; int j = quesNum, overValue, forLoop = 100; for (int loop = 1; loop < loopCount; loop++) { aa = r.nextInt(10+1); abc = (int) aa; String[] userAnswer = new String[x]; JOptionPane.showMessageDialog(null,abc); if(abc < x) { userAnswer[j] = JOptionPane.showInputDialog(null,"Question "+quesNum+"\n"+questions[abc]+"\n\nA: "+a[abc]+"\nB: "+b[abc]+"\nC: "+c[abc]+"\nD: "+d[abc]); if(userAnswer[j].equals(answers[j])) { JOptionPane.showMessageDialog(null,"Correct. \nThe Correct Answer is "+answers[abc]); } else { JOptionPane.showMessageDialog(null,"Wrong. \n The Correct Answer is "+answers[abc]); }//else }//if }//for

  • jquery split() and indexOf results in "Object doesn't support this property or method"

    - by chris
    I have the following code: var selected = $('#hiddenField').val().split(","); ... if (selected.indexOf(id) > 0) { ... set value ... } I'm dynamically creating a CheckBoxList, and trying to remember the state of the checkboxes by putting the selected IDs into the hidden field. I get an error stating that "Object doesn't support this property or method". My assumption is that selected is an array, which should support indexOf. Is that incorrect?
