JavaScript - Ways To Set Chrome Extension
Similar TutorialsFirst off I apologize If this is in the wrong section of this forum. So I got this concept that I think Is pretty cool. I dont know If there's anything like It out there, If there is, let me know. This is the concept: You click the icon and down pops a map in which there's a circle (like this: imgur: the simple image sharer) You can resize the circle and move it around. Underneath the map there's a box where you can type your search. Let's say you search for "puppies" in Brooklyn, New York The idea is that It'll scan all the coordinates inside the circle and search for photos in google images containing those coordinates in the GPS info (EXIF).This can be useful If you for example wants to search for photos taken in your city, or even in your neighborhood. I can see many uses for this. The thing is, I don't know any programming languages so I can't do this myself. I don't even know where to start. I'm looking for a kind soul to help me with this, I don't have any money so I'm not looking to pay anyone to do this for me. I just want some help getting started, or if someone would be kind enough to do It for free. (Though that Is very unlikely.) Thanks in advance! Sorry for my bad english, it is not my native language.

I want to download text file generated in a textarea here my download.php file code structure goes : <?php if(empty($_POST['filename']) || empty($_POST['content'])){ exit; } $filename = preg_replace('/[^a-z0-9\-\_\.]/i','',$_POST['filename']); header("Cache-Control: "); header("Content-type: text/plain"); header('Content-Disposition: attachment; filename="'.$filename.'"'); echo $_POST['content']; ?> and the javascript used (function($){ $.generateFile = function(options){ options = options || {}; if(!options.script || !options.filename || !options.content){ throw new Error("Please enter all the required config options!"); } var iframe = $('<iframe>',{ width:1, height:1, frameborder:0, css:{ display:'none' } }).appendTo('body'); and the script.js $(document).ready(function(){ $('#download').click(function(e){ $.generateFile({ filename : 'export.txt', content : $('textarea').val(), script : 'download.php' }); e.preventDefault(); }); by these assets i created a web page consisting a TEXTAREA , by entering some text on the textarea and clicking on the download button , a text files is generated and downloaded on the user's system, I packed the source code as a CRX file to use it as a CHROME extension, but while using the extension,the files are'nt generated, while the webpage works absolutely fine !!! Does anyone know of a way I can create an array using words on new lines, without quotes, or a way I can make all of the lines separately in quotes and separated by commas? (I have 118,628 words, so I can't do it by hand.) Any help is appreciated. Thanks to anyone who answers.
I'm still a beginner in js core so please forgive if the question is too fundamental. In the following example PositionedRectangle is a subclass of Rectangle, all 3 methods of prototype inheritance seem to produce the same results, method 1 is from the authors book (Flanagan's Definitive Guide 5ed) example 9-3, and method 2 is from his website example 9-3, and method 3 is my own; Code:
// method 1 seems most complicated
function heir(p) {
function f(){};
f.prototype =p;
return new f();
}
PositionedRectangle.prototype = heir(Rectangle.prototype);
//method 2
PositionedRectangle.prototype = new Rectangle();
//method 3 seems most straight forward (I don't know if it's correct but works ok)
PositionedRectangle.prototype = Rectangle.prototype;
Thank you Gents, J. Since the upgrade from chrome 9 to chrome 10 my script is showing an error in my variables when i use boolean expressions. they changed to version V8, Chrome's JavaScript engine. Here is the function function get_form_value(n){ e=document.getElementById(n); if ((e.value)&&(e.value != "")&&(!e.options)) return e.value; if ((e.selectedIndex)&&(e.selectedIndex>0) &&(e.options[e.selectedIndex].value !="")) return e.options[e.selectedIndex].value; // select if ((e.text)&&(e.text.value !="")) continue; if ((e.selectedIndex)&&(e.selectedIndex>0) &&(e.options[e.selectedIndex].text !="")) return e.options[e.selectedIndex].text; // select if ((e.checkbox)&&(e.checkbox.checked)) return true; return false; } When i run it it shows a syntax error: Can someone please help me fix this? I have a piece of code for adding categories to a shopping site, which was working fine but now doesn't submit after I made changes to try to validate the type image chosen for that category. I'll post the original and then changed code, anyone think they can see why it's not running? Code: function checkCategoryForm()
{
with (window.document.frmCategory) {
if (isEmpty(catName, 'Enter category name')) {
return;
} else if (isEmpty(catDescription, 'Enter category description')) {
return;
} else {
submit();
}
}
}
Code: function getFileExtension(filename)
{
var ext = /^.+\.([^.]+)$/.exec(filename);
return ext == null ? "" : ext[1];
}
function checkCategoryForm()
{
with (window.document.frmCategory) {
if (isEmpty(catName, 'Enter category name')) {
return;
} else if (isEmpty(catDescription, 'Enter category description')) {
return;
} else {
if (getFileExtension(fileImage) = '.jpg' || '.jpeg' || '.png' || '.gif' ){
submit();
} else {
alert("Enter this image format is not allowed, only .jpg, .png or .gif");
return;
}
}
}
}
Thanks! The mounds of RegExp data will take me days to sift through can someone help me create a regular expression to find a file extension? (all characters after a period) I have already gotten this far: .+\. to find everything before and including the period; and I was hoping to integrate the caret to say everything but .+\. But I just can't get it to work... Note: I will be writing a file to the server with JScript ASP. The file name will be passed to the script that writes the file, and I want to make sure that in addition to removing any possible code from the line being written, that I also prevent an executable file from being created. I will be searching for certain extensions and returning if anything else is found. Hello. I have used the Firefox extension Linky for a very long time, it is one of my most used extensions bar none. However, one of the most attractive features of it broke somewhere in the updating from Firefox 3-4, as far as i know. I didn't find out about it until recently, due to never bothering to update past Firefox 3 until just a little while ago. This feature was the 'Select already visited links' option, which also works in reverse, letting you unselect all links to pages you've already visited. (Or rather, have listed in your browser history) Now, i am a complete noob when it comes to JavaScript, and i have very little knowledge about this type of programming, so i have no chance to fix this myself. This, is the reason i came here. I hope someone will be able to take a quick look at this code, and maybe tell me how to fix it, or make a workaround, or something. I really want to get it working again. I am almost certain that the problem lies in this section of the code: Code: LinkySelect.prototype.checkVisited = function() {
var gGlobalHistory = opener.Components.classes["@mozilla.org/browser/global-history;1"].getService(Components.interfaces.nsIGlobalHistory);
var cbox = this.getChecked(document.getElementById("cvbox"));
var selectlinks = document.getElementById("selectlinks");
var last = selectlinks.getRowCount();
for (var i = 0; i < last; i++) {
var tmp = selectlinks.getItemAtIndex(i);
if (gGlobalHistory.isVisited(tmp.getAttribute("value"))) {
tmp.setAttribute("checked", this.setChecked(cbox));
}
}
this.updateInfo();
}
Also, the Error Console reports this; Code: Error: opener.Components.classes['@mozilla.org/browser/global-history;1'] is undefined Source File: chrome://linky/content/select-links.js Line: 28 I hope that will tell someone something. I almost feels like it tells me something, but it's been years and years since i last tried to study this type of programming. Any help with this is appreciated. Thanks in advance for your time.

Hi, I'm creating an extension on Firefox that wishes to parse the source of a page that the user is currently viewing for specific information. I've gotten as far as creating a simple extension with a button and when I click on it, it will show the url of the page I am currently viewing through: content.location.href All the examples I've seen so far concerning viewing the source forces you to either use the 'view-source:' convention or the 'xmlhttprequest' method. But these examples seems to be meant to be called within a web page and not an extension. When I cut and paste with these examples, I only get the source for the actual chrome portion of Firefox. I've tried modifying some of the examples to include 'content.document....etc' to reference what's being displayed in the browser, but it doesn't seem to work. Can anyone provide sample or reference code so I can extract the page source of my current window from an extension? Thanks! Hi, I am kinda new to java scripting and here is what i am trying to do. I have a folder "A" with 10 files, all with .txt extensions in it. I want a java script to open all the 10 files in the folder "A" and change the extensions to .js and save it in a folder "B". Can some one help. Thanks a lot in advance. Hi All, I have written a chrome extension which will redirect to all hrefs for a given source urls in current tab.. But i don't know why all of a sudden it stops executing after reaching some page. I am attaching my code as attachment. Can any one help me out. Thanks in advance. Go figure huh??? Anyways I have a script a co-worker wrote and it works in FF and Chrome but IE will not work. Get's a 'activeTab' is null or not an object error, I checked for commas and fixed a semi-colon that was missing in two spots but not change in IE.

I need to disable some keys from their default behaviour in Google Chrome on Windows with javascript. The script below works for most keys but not for F10, left Windows key, right Windows key, NumLock and left Alt. (which are the keys I need to disable) Code: <script type="text/javascript">
addEventListener("keydown", function (event) {
if(KeyID == 121 KeyID == 91 || KeyID == 92 || KeyID == 144|| KeyID == 18 ){
event.preventDefault();
}
}, true);
</script>
I have also without luck tried event.stopPropagation () - event.cancelBubble = true - return false og void(). I would like to know if their is a solution or it simply isn't possible to disable the mentioned keys. Script runs fine in latest stable release of Firefox 3 but breaks in chrome Code: function fixCSS(){
var styles={
'Yotsuba':'http://static.4chan.org/css/yotsuba.9.css',
'Yotsuba B':'http://static.4chan.org/css/yotsublue.9.css',

for(j in styles){
if(document.getElementsByTagName('link')[i].title==j)document.getElementsByTagName('link')[i].href=styles[j];

Error message reported by Chrome's "JavaScript Console": Uncaught TypeError: Cannot call method 'removeChild' of undefined killCotten Screenshot of debugger: Hello again; I am testing in Firefox( two versions ), Chrome, Opera (two versions), Safari on Mac OSX and am seeing a peculiarity. Code: <div id="dialog" style="position:absolute;top:50px;left:600px;"> <div id="head"><p id="panelTitle">Item Info:</p></div> <p>Drag this panel to move </p> <pre id="target1"><img id="srcImg" src="windows/img/front_window.jpg" alt="test" /></pre> <pre id="target2"> </pre> <div id="closer"><p class="dialog"><a id="dClose" href="javascript:">Close</a></p></div> event listener assigned to a separate anchor tag makes this markup visible and drag-able. The mousemove event listener for dragging is assigned to the parent div, id='dialog' In Firefox and Google's Chrome browser, if I mousedown on the image and try to drag, the system tries to move and copy the image. When I release the mouse, the whole panel sticks to the pointer and moves with the pointer until I click on it. The Question: What event would I do preventDefault, cancelbubble, or return false to get around this? (perhaps for a separate post, how would I prevent the client form copying content?) Safari will do the same accept that it will not stick to the mouse pointer position on mouseup. In Opera, it works fine (accept the earlier verison, v9x leaves a trail of ghost lines where the panel was moved from) I have a pc with I.E. and have not yet tested this specific issue. Thank you for your time and attention JK |
