  • getting an error on jslint while creating a new object using javascript

    - by user3712689
    For some reason this code is giving a lint. I can't really figure out why. It says: 'was expecting a assignment or function call, and instead saw an expression.' What does that mean? window.onload = function (){ function SuspectOne (naam, leeftijd, wie){ this.naam = Spencer Hawes; this.leeftijd = 22; this.wie = zoon van de man; } function SuspectTwo (naam, leeftijd, wie){ this.naam = Tyrone Biggums; this.leeftijd = 28; this.wie = lokale herionejunk; } function SuspectThree (naam, leeftijd, wie){ this.naam = Ellie Campbell Hawes; this.leeftijd = 40; this.wie = vrouw van de man; } var verdachten = new Array[]; verdachten[0] = new Verdachte("Spencer Hawes", 22, "zoon van de man"); verdachten[1] = new Verdachte("Tyrone Biggums", 28, "lokale herionejunk"); verdachten[2] = new Verdachte("Ellie Spencer Hawes", 40, "vrouw van de man"); for(x=0; x<verdachten.length; x++){ console.log("De verdachte is de " + verdachten[x].leeftijd + "jaar oud " + verdachten[x].naam + ", de " + verdachten[x].wie); } }; Can someone help me with this? I would really like a lint free code.

  • Refactoring a javascript array rotate function

    - by ideotop
    I wrote a rotate function, but I'm not satisfied with it: var pixels=['011','110','000']; var result=new Array(); result=['000','000','000']; for ( y=0; y<(pixels.length); y++ ){ for ( x=0; x<(pixels.length); x++ ){ var newx=0,newy=0; if ( clock ){ if ( x< r.x && y< r.y ) {newx=x+2;newy=y ;}//top left if ( x==r.x && y< r.y ) {newx=x+1;newy=y+1;}//top if ( x> r.x && y< r.y ) {newx=x ;newy=y+2;}//top right if ( x< r.x && y==r.y ) {newx=x+1;newy=y-1;}//left if ( x==r.x && y==r.y ) {newx=x ;newy=y ;}//center if ( x> r.x && y==r.y ) {newx=x-1;newy=y+1;}//right if ( x< r.x && y> r.y ) {newx=x ;newy=y-2;}//bottom left if ( x==r.x && y> r.y ) {newx=x-1;newy=y-1;}//bottom if ( x> r.x && y> r.y ) {newx=x-2;newy=y ;}//bottom right } else { if ( x< r.x && y< r.y ) {newx=x ;newy=y+2;}//top left if ( x==r.x && y< r.y ) {newx=x-1;newy=y+1;}//top if ( x> r.x && y< r.y ) {newx=x-2;newy=y ;}//top right if ( x< r.x && y==r.y ) {newx=x+1;newy=y+1;}//left if ( x==r.x && y==r.y ) {newx=x ;newy=y ;}//center if ( x> r.x && y==r.y ) {newx=x-1;newy=y-1;}//right if ( x< r.x && y> r.y ) {newx=x+2;newy=y ;}//bottom left if ( x==r.x && y> r.y ) {newx=x+1;newy=y-1;}//bottom if ( x> r.x && y> r.y ) {newx=x ;newy=y-2;}//bottom right } //inject(result,newx,newy,pixels[y][x]) } } does someone now how to write a cleaner code for this rotate (clock and counter-clock) function ?

  • Javascript substrings multiline replace by RegExp

    - by Radek Šimko
    Hi, I'm having some troubles with matching a regular expression in multi-line string. <script> var str="Welcome to Google!\n"; str = str + "We are proud to announce that Microsoft has \n"; str = str + "one of the worst Web Developers sites in the world."; document.write(str.replace(/.*(microsoft).*/gmi, "$1")); </script> http://jsbin.com/osoli3/3/edit As you may see on the link above, the output of the code looks like this: Welcome to Google! Microsoft one of the worst Web Developers sites in the world. Which means, that the replace() method goes line by line and if there's no match in that line, it returns just the whole line... Even if it has the "m" (multiline) modifier...

  • JavaScript Exception/Error Handling Not Working

    - by Seán Hayes
    This might be a little hard to follow. I've got a function inside an object: f_openFRHandler: function(input) { console.debug('f_openFRHandler'); try{ //throw 'foo'; DragDrop.FileChanged(input); //foxyface.window.close(); } catch(e){ console.error(e); jQuery('#foxyface_open_errors').append('<div>Max local storage limit reached, unable to store new images in your browser. Please remove some images and try again.</div>'); } }, inside the try block it calls: this.FileChanged = function(input) { // FileUploadManager.addFileInput(input); console.debug(input); var files = input.files; for (var i = 0; i < files.length; i++) { var file = files[i]; if (!file.type.match(/image.*/)) continue; var reader = new FileReader(); reader.onload = (function(f, isLast) { return function(e) { if (files.length == 1) { LocalStorageManager.addImage(f.name, e.target.result, false, true); LocalStorageManager.loadCurrentImage(); //foxyface.window.close(); } else { FileUploadManager.addFileData(f, e.target.result); // add multiple files to list if (isLast) setTimeout(function() { LocalStorageManager.loadCurrentImage() },100); } }; })(file, i == files.length - 1); reader.readAsDataURL(file); } return true; LocalStorageManager.addImage calls: this.setItem = function(data){ localStorage.setItem('ImageStore', $.json_encode(data)); } localStorage.setItem throws an error if too much local storage has been used. I want to catch that error in f_openFRHandler (first code sample), but it's being sent to the error console instead of the catch block. I tried the following code in my Firebug console to make sure I'm not crazy and it works as expected despite many levels of function nesting: try{ (function(){ (function(){ throw 'foo' })() })() } catch(e){ console.debug(e) } Any ideas?

  • Evaluating Javascript Arrays

    - by FailBoy
    I have an array that contains an array of arrays if that makes any sense. so for example: [[1, 2, 3], [2, 3, 4], [3, 4, 5], [4, 5, 6]] I want to see whether an array exists withing the array, so if [1, 2, 3] is duplicated at all. I have tried to use the .indexOf method but it does find the duplicate. I have also tried Extjs to loop through the array manually and to evaluate each inner array, this is how I did it: var arrayToSearch = [[1, 2, 3], [2, 3, 4], [3, 4, 5], [4, 5, 6]]; var newArray = [1, 2, 3]; Ext.each(arrayToSearch, function(entry, index){ console.log(newArray, entry); if(newArray == entry){ console.log(index); }; }); This also does not detect the duplicate. the console.log will output [1, 2, 3] and [1, 2, 3] but will not recognize them as equal. I have also tried the === evaluator but obviously since == doesn't work the === wont work. I am at wits end, any suggestions.

  • Rails: Internationalization of Javascript Strings?

    - by Matt Rogish
    So, we have an existing Rails 2.3.5 app that does not support Internationalization at all. Now, I'm well familiar with Rails I8n stuff, but we have a LOT of output strings inside /javascripts/. I'm not a huge fan of this approach, but unfortunately it is too late to fix it now. How might we internationalize strings stored in JS files in a Rails app? Rails doesn't even serve the JS files... I'm thinking I could always have the Rails app serve up the JS files, but that seems pretty gross. Are there plugins to do this? Yikes.

  • sort outer array based on values in inner array, javascript

    - by ptrn
    I have an array with arrays in it, where I want to sort the outer arrays based on values in a specific column in the inner. I bet that sounded more than a bit confusing, so I'll skip straight to an example. Initial data: var data = [ [ "row_1-col1", "2-row_1-col2", "c-row_1-coln" ], [ "row_2-col1", "1-row_2-col2", "b-row_2-coln" ], [ "row_m-col1", "3-row_m-col2", "a-row_m-coln" ] ]; Sort data, based on column with index 1 data.sortFuncOfSomeKind(1); where the object then would look like this; var data = [ [ "row_2-col1", "1-row_2-col2", "b-row_2-coln" ], [ "row_1-col1", "2-row_1-col2", "c-row_1-coln" ], [ "row_m-col1", "3-row_m-col2", "a-row_m-coln" ] ]; Sort data, based on column with index 2 data.sortFuncOfSomeKind(2); where the object then would look like this; var data = [ [ "row_m-col1", "3-row_m-col2", "a-row_m-coln" ], [ "row_2-col1", "1-row_2-col2", "b-row_2-coln" ], [ "row_1-col1", "2-row_1-col2", "c-row_1-coln" ] ]; The big Q Is there an existing solution to this that you know of, or would I have to write one myself? If so, which would be the easiest sort algorithm to use? QuickSort? _L

  • How to REALLY focus a link using jQuery / javascript

    - by Bobby Jack
    Calling the jQuery focus() method on a link appears to only partially focus the link. Whilst the link has focus to the extent that pressing ENTER follows the link, it doesn't take on the default outline styling (or adopt any styling set via the :focus pseudo-class), nor is the tab-order correctly 'entered'. Any ideas on how to resolve this? (results observed in Firefox 3.6.2)

    Page has menu items that would replace a 'div id=foo_(current menu item)' with 'div id=foo_(selected menu item)' in 'div class=foo' Here's what I've got, and try to keep your breakfast down... $('#t1').click(function() { $('#attorney').show(); $('#insurance,#financial,#estate,#trust,#death').hide(); }); $('#t2').click(function() { $('#insurance').show(); $('#attorney,#financial,#estate,#trust,#death').hide(); }); $('#t3').click(function() { $('#financial').show(); $('#attorney,#insurance,#estate,#trust,#death').hide(); }); $('#t4').click(function() { $('#estate').show(); $('#attorney,#insurance,#financial,#trust,#death').hide(); }); $('#t5').click(function() { $('#trust').show(); $('#attorney,#insurance,#financial,#estate,#death').hide(); }); $('#t6').click(function() { $('#death').show(); $('#attorney,#insurance,#financial,#estate,#trust').hide(); });

  • JavaScript Loop and wait for function

    - by Fluidbyte
    I have a simple single-dimension array, let's say: fruits = ["apples","bananas","oranges","peaches","plums"]; I can loop thru with with $.each() function: $.each(fruits, function(index, fruit) { showFruit(fruit); }); but I'm calling to another function which I need to finish before moving on to the next item. So, if I have a function like this: function showFruit(fruit){ $.getScript('some/script.js',function(){ // Do stuff }) } What's the best way to make sure the previous fruit has been appended before moving on?

  • Find consecutive "//" in regex in JavaScript

    - by iOnline247
    I gave it a college try, but I'm stumped. I'm trying to find consecutive slashes within a string. The rest of the regex works great, but the last part I can't quite get. Here's what I have: val.match( /^[\/]|[~"#%&*:<>?\\{|}]|[\/|.]$/ ) and finding this thread, I decided to update my code to no avail: RegEx to find two or more consecutive chars val.match( /^[\/]|[\/]{2,}|[~"#%&*:<>?\\{|}]|[\/|.]$/ ) What do I need to get this thing going?

    - by Tam
    I want to have java script clicking a link on the page..I found something on the net that suggests adding a function like this: function fireEvent(obj,evt){ var fireOnThis = obj; if( document.createEvent ) { var evObj = document.createEvent('MouseEvents'); evObj.initEvent( evt, true, false ); fireOnThis.dispatchEvent(evObj); } else if( document.createEventObject ) { fireOnThis.fireEvent('on'+evt); } } Then call it using: fireEvent(document.getElementById('edit_client_link'),'click'); This seems to work fine for FF but with IE it doesn't work!
