recursive wget with hotlinked requisites

- by dongle

I often use wget to mirror very large websites. Sites that contain hotlinked content (be it images, video, css, js) pose a problem, as I seem unable to specify that I would like wget to grab page requisites that are on other hosts, without having the crawl also follow hyperlinks to other hosts. For example, let's look at this page https://dl.dropbox.com/u/11471672/wget-all-the-things.html Let's pretend that this is a large site that I would like to completely mirror, including all page requisites – including those that are hotlinked. wget -e robots=off -r -l inf -pk ^^ gets everything but the hotlinked image wget -e robots=off -r -l inf -pk -H ^^ gets everything, including hotlinked image, but goes wildly out of control, proceeding to download the entire web wget -e robots=off -r -l inf -pk -H --ignore-tags=a ^^ gets the first page, including both hotlinked and local image, does not follow the hyperlink to the site outside of scope, but obviously also does not follow the hyperlink to the next page of the site. I know that there are various other tools and methods of accomplishing this (HTTrack and Heritrix allow for the user to make a distinction between hotlinked content on other hosts vs hyperlinks to other hosts) but I'd like to see if this is possible with wget. Ideally this would not be done in post-processing, as I would like the external content, requests, and headers to be included in the WARC file I'm outputting.

Dynamic jQuery dialog after data append w/o reloading page. Possible?

- by Arun

Howdy, So I have a page with an enormous table in a CRUD interface of sorts. Each link within a span calls a jQuery UI Dialog Form which fetches it's content from another page. When the action taking place (in this case, a creation) has completed, it appends the resulting new data to the table and forces a resort of the table. This all happens within the JS and the DOM. The problem with this, is that the new table row's CRUD links don't actually trigger the dialog form creation as all the original links in spans are only scanned on document.ready and since I'm not reloading the page, the new links cannot be seen. Code is as follows: $(document).ready(function() { var $loading = $('<img src="/images/loading.gif" alt="Loading">'); $('span a').each(function() { var $dialog = $('<div></div>') .append($loading.clone()); var $link = $(this).one('click', function() { // Dialog Stuff success: function(data) { $('#studies tbody').append( '<tr>' + '<td><span><a href="./?action=update&study=' + data.study_id + '" title="Update Study">Update</a></span></td>' + '</tr>' ); fdTableSort.init(#studies); // This re-sorts the table. $(this).dialog('close'); } $link.click(function() { $dialog.dialog('open'); return false; }); return false; }); }); }); Basically, my question is if there is any way in which to trigger a jQuery re-evaluation of the pages links without forcing me to do a browser page refresh?

Does a jQuery selector by id always work without quotes and # sign?

- by anarinsky

I suddenly found that while using Mozilla / jQuery v1.8.2 I do not need to use the id with quotes and # sign. For example, $(bt2) works the same as $(“#bt2”), see the code below. Will this selector always work and are there any potential drawbacks from using this shorter form of selection? <html> <head> <title>append</title> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> $(document).ready (function(){ $(bt2).click(function(){ $(i1).append("<li>a4</li>", "<li>a5</li>"); }); }); </script> </head> <body> <button id="Button1">Append List</button> <ul id="i1"> <li>a1</li> </ul> </body> </html>

How to make this jQuery snippet work in Internet Explorer?

- by George Edison

If there was ever a time to hate IE, this is it. This code begins with a box with content. When the button is clicked, the box is supposed to drop down and fade-in. <html> <script type="text/javascript" src="jquery.js"></script> <script type='text/javascript'> function Test() { var item_height = $('#test').height(); $('#test').height(0); $('#test').css('opacity','0'); $('#test').animate({ height: item_height, opacity: '1' },400); } </script> <body>  <div id="test" style='border: 1px solid black;'> Content<br> Content<br> Content<br> Content<br> Content </div>  <br><br> <div style='position: absolute; top: 150px; left: 10px;'> <button onclick='Test();'>Test</button> </div> </body> </html> This very simple example works on Chrome, Safari, and Opera. But Internet Explorer? No. How can I (if it's even possible) fix this so that it works in IE?

redirecting _top page from asp:login control in iframe onloggedin

So yeah, Im building a little authenticated content(.NET app) to a large html site managed by another group.

Load function in jquery

- by user345579

Hi, I am relatively new to jquery and would like to know why the below code wouldn't work. I am trying to access the content from a file residing on my site and not outside. Is it because I have the jquery lib loading from google and not my site? The error message that I get in IE browser is "Access Denied". I am confused why the access is denied if I am trying to load a file from the same server and even same folder. <html> <head> <script type="text/javascript" language="JavaScript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" language="JavaScript"> $(document).ready(function(){ $("#response").load("http://www.mydomain.com/loadme.php?route=links/getlinks&path=2"); }); </script> </head> <body> <div id="response" style="border: 1px solid #000;height:500px;"> </div> </body> </html> any one please help me. thanks

Parsing html output and executing javascript

I have this function: function parseScript(_source) { var source = _source; var scripts = new Array(); while(source.indexOf("<script") > -1 || source.indexOf("</script") > -1) { var s = source.indexOf("<script"); var s_e = source.indexOf(">", s); var e = source.indexOf("</script", s); var e_e = source.indexOf(">", e); scripts.push(source.substring(s_e+1, e)); source = source.substring(0, s) + source.substring(e_e+1); } for(var i=0; i<scripts.length; i++) { try { eval(scripts[i]); } catch(ex) { } } return source; } It parses and execute Javascript wonderfully except the when in <script type='text/javascript' src='scripts/gen_validatorv31.js'></script> the src file never gets executed.

JavaScript: Is there a better way to retain your array but efficiently concat or replace items?

- by Michael Mikowski

I am looking for the best way to replace or add to elements of an array without deleting the original reference. Here is the set up: var a = [], b = [], c, i, obj; for ( i = 0; i < 100000; i++ ) { a[ i ] = i; b[ i ] = 10000 - i; } obj.data_list = a; Now we want to concatenate b INTO a without changing the reference to a, since it is used in obj.data_list. Here is one method: for ( i = 0; i < b.length; i++ ) { a.push( b[ i ] ); } This seems to be a somewhat terser and 8x (on V8) faster method: a.splice.apply( a, [ a.length, 0 ].concat( b ) ); I have found this useful when iterating over an "in-place" array and don't want to touch the elements as I go (a good practice). I start a new array (let's call it keep_list) with the initial arguments and then add the elements I wish to retain. Finally I use this apply method to quickly replace the truncated array: var keep_list = [ 0, 0 ]; for ( i = 0; i < a.length; i++ ){ if ( some_condition ){ keep_list.push( a[ i ] ); } // truncate array a.length = 0; // And replace contents a.splice.apply( a, keep_list ); There are a few problems with this solution: there is a max call stack size limit of around 50k on V8 I have not tested on other JS engines yet. This solution is a bit cryptic Has anyone found a better way?

jQuery .val() Selector Confusion

- by Matt Dawdy

I've kind of written myself into a corner, and was hoping there was an "easy" way out. I'm trying to loop through a series of things on my page, and build a key:value pair. Here is my structure: <div class="divMapTab" id="divMapTab34"> <div class="divFieldMap"> <select class="selSrc" id="selTargetnamex"><options....></select> </div> </div> <div class="divMapTab" id="divMapTab87"> <div class="divFieldMap"> <select class="selSrc" id="selTargetnamex"><options....></select> </div> </div> It's way more complicated than that, and there are many select elements inside of each divFieldMap div. Here is my JS function that is building my string: function Save() { var sSaveString = ''; $('.divMapTab').each(function() { var thisId = this.id; $('.selSrc', "#" + thisId).each(function() { var thisSubId = this.id; //alert(thisSubId); <-- HERE IS THE PROBLEM var sTargetCol = thisSubId.replace('selTarget', ''); var sValue = this.val(); sSaveString += sTargetCol + '¸' + sValue + '·'; }); }); } On the line that has the alert box and the text "HERE IS THE PROBLEM" is that I'm trying to get the selected value of the "current" select input element, but the id of that element isn't unique (I thought it would be, but I screwed up). Is there a good way, inside of an "each" type of jQuery statement, to use "this" to get the exact select element that I really am looking for, even if it doesn't have a unique id?

How to fill in form field, and submit, using javascript?

How would I, using Javascript, fill in the username and press Go...? I would prefer to use plain JS, rather than a library like jquery.

jQuery replacement for Default Button or Link

- by pyccki

As everyone knows, that default button doesn't work in FF, only IE. I've tried to put in the tag or in the and it's not working. I've found a js script to fix this issue, but for some reason it's not working for me. This script for a submit button, i need to use it for a LinkButton, which is should be the same. Link: <div id="pnl"> <a id="ctl00_cphMain_lbLogin" title="Click Here to LogIn" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$cphMain$lbLogin", "", true, "Login1", "", false, true))">Log In</a> <input name="ctl00$cphMain$UserName" type="text" id="ctl00_cphMain_UserName" /> <input name="ctl00$cphMain$UserName" type="text" id="ctl00_cphMain_UserName1" /> </div> <script> $(document).ready(function() { $("#pnl").keypress(function(e) { if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) { $("a[id$='_lbLogin']").click(); return true; } }); }); I know that i can override original function "*WebForm_FireDefaultButton*" in This post, but i really wanted to get this one to work. Thanx in advance!!!

Sanitizing usser input before adding it to the DOM in Javascript

- by I GIVE TERRIBLE ADVICE

I'm writing the JS for a chat appication I'm working on in my free time, and I need to have HTML identifiers that change according to user submitted data. This is usually something conceptually shaky enough that I would not even attempt it, but I don't see myself having much of a choice this time. What I need to do then is to escape the HTML id to make sure it won't allow for XSS or breaking HTML. Here's the code: var user_id = escape(id) var txt = '<div class="chut">'+ '<div class="log" id="chut_'+user_id+'"></div>'+ '<textarea id="chut_'+user_id+'_msg"></textarea>'+ '<label for="chut_'+user_id+'_to">To:</label>'+ '<input type="text" id="chut_'+user_id+'_to" value='+user_id+' readonly="readonly" />'+ '<input type="submit" id="chut_'+user_id+'_send" value="Message"/>'+ '</div>'; What would be the best way to escape id to avoid any kind of problem mentioned above? As you can see, right now I'm using the built-in escape() function, but I'm not sure of how good this is supposed to be compared to other alternatives. I'm mostly used to sanitizing input before it goes in a text node, not an id itself.

CodeIgniter subfolders and URI routing

- by shummel7845

I’ve read the manual on URI routing and views and something is not clicking with me. In my views folder, I have a subfolder called products. In there is a file called product_view. In my controller, I have: function index() { $data['title'] = 'Product Overview'; $data['main_content'] = 'products/product_view'; $this->load->view('templates/main.php', $data); } The template loads a header view, a footer view and a navigation view, plus the view as a main content variable. In my URI routing, I have: $route['products/product-overview'] = 'products/product_view']; This causes a 404 error when I try to go to domain.com/products/product-overview. Do I need to do something with my .htaccess? If so, what? Here is my .htaccess: Options +FollowSymLinks Options -Indexes DirectoryIndex index.php RewriteEngine on RewriteCond $1 !^(index\.php|resources|images|css|js|robots\.txt|favicon\.ico) RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?/$1 [L,QSA] I’d appreciate some specific help, as the documentation isn’t specific on how to address this. I’ve done a little searching in the forums, and didn’t see anything, but I’m posting this while I keep looking.

How do I unbind another jQuery function on .click()?

- by Mike Barwick

I have this script that run to fix my menu bar to the browser on scroll. Nothing really needs to change here (works as it should). However, you may need it... var div = $('#wizMenuWrap'); var editor = $('#main_wrapper'); var start = $(div).offset().top; $(function fixedPackage(){ $.event.add(window, "scroll", function() { var p = $(window).scrollTop(); $(div).css('position',((p)>start) ? 'fixed' : 'static'); $(div).css('top',((p)>start) ? '0px' : ''); //Adds TOP margin to #main_wrapper (required) $(editor).css('position',((p)>start) ? 'relative' : 'static'); $(editor).css('top',((p)>start) ? '88px' : ''); }); }); Now for the issue at hand. I have another script function that calls a modal pop-up (which again works as it should). However, it's not slick from a UI perspective when I scroll the page when the modals open. So I want to disable the script above when the modal script below is called. In other words, when I click to open the modal pop-up, the script above shouldn't work. $(function () { var setUp = $('.setupButton'); // SHOWS SPECIFIED VIEW $(setUp).click(function () { $('#setupPanel').modal('show'); //PREVENTS PACKAGE SELECT FIXED POSITION ON SCROLL $(setUp).unbind('click',fixedPackage); }); }) As you can see above, I tried to unbind the scroll function (the first code snippet), but this is not correct. These two scripts are in two separate js libraries.

Automated browser testing: How to test JavaScript in web pages?

- by Dave

I am trying to write an application that will test a series of web-pages programmatically. The web pages being tested have JavaScript embedded within them which alter the structure of the HTML when they complete execution. It is then the goal to take the final HTML (post-execution of the embedded JavaScript) and compare it against a known output. Essentially, the Input --- Output for the test application is: URL ---[retrieve HTML]--- HTML ---[execute JS, then compare]--- PASS/FAIL Here is the challenge: I have been unable to find a solution that is able to take the HTML I retrieve from the URL and process the JavaScript, as a browser would, and generate the final HTML a user might see from "View Source" on the same page within the browser. It would be very surprising if this sort of approach has not been made before, so I'm hoping someone out there knows of a fitting solution for this application/problem? If at all possible, I'm hoping for a solution that integrates with .NET (I've tried using the WebBrowser, with no luck). However, if there is an existing 3rd party application that can do exactly this, that would be quite acceptable. Thanks in advance for the suggestions! Dave
