  • Fix internal links in JS

    - by FB55
    I just created a script which extracts the article out of a webpage via server-side JS. (If your interested: it's used for http://pipes.yahoo.com/fb55/expandr .) I just got a little problem with internal links. Some pages include links like: /subfolder/subpage.html What I would need to do is fixing them and setting there root, like this: protocol://secondlevel.firstlevel/subfolder/subpage.html I'm using E4X for processing the page. I don't want to show my current creepy try, it's buggy and slow. Does anybody have a solution for me?

  • Cached Jquery selector behavior that I do not understand

    - by gaoshan88
    Given the following code why am I getting different values for a and b? I would have thought they would return the same thing: (function() { var a = $('#foo'); var Test = function(){ console.log(a); //outputs 'jQuery()' var b = $('#foo'); console.log(b); //outputs 'jQuery(select#foo)' which is what I want }; })(); This question stems from me trying to stick frequently used selectors into vars. Originally I was doing it in each method (like I did with var b in the above example) but then I found I needed to use the selectors in multiple methods so I moved the assignment out to be available (or so I thought) to all of the methods in that anonymous function. As you can see, it does not work. Why is this?

  • show tweets inside div from an asynchronous loop

    - by ak_47
    Am trying to laod tweets into a div after looping them from yahoo placemaker. They are loading on the div but the information shown by them is placemaker's last result. This is the code.. function getLocation(user, date, profile_img, text,url) { var templates = []; templates[0] = '<div><div></div><h2 class="firstHeading">'+user+'</h2><div>'+text+'</div><div><p><a href="' + url + '"target="_blank">'+url+'</a></p></div><p>Date Posted- '+date+'</p></div>'; templates[1] = '<table width="320" border="0"><tr><td class="user" colspan="2" rowspan="1">'+user+'</td></tr><tr><td width="45"><a href="'+profile_img+'"><img src="'+profile_img+'" width="55" height="50"/></a></td><td width="186">'+text+'<p><a href="' + url + '"target="_blank">'+url+'</a></p></td></tr></table><hr>'; templates[2] = '<div><div></div><h2 class="firstHeading">'+user+'</h2><div>'+text+'</div><div><p><a href="' + url + '"target="_blank">'+url+'</a></p></div><p>Date Posted- '+date+'</p></div>'; templates[3] = '<table width="320" border="0"><tr><td class="user" colspan="2" rowspan="1">'+user+'</td></tr><tr><td width="45"><a href="'+profile_img+'"><img src="'+profile_img+'" width="55" height="50"/></a></td><td width="186">'+text+'<p><a href="' + url + '"target="_blank">'+url+'</a></p></td></tr></table><hr>'; var geocoder = new google.maps.Geocoder(); Placemaker.getPlaces(text, function (o) { console.log(o); if (!$.isArray(o.match)) { var latitude = o.match.place.centroid.latitude; var longitude = o.match.place.centroid.longitude; var myLatLng = new google.maps.LatLng(latitude, longitude); var marker = new google.maps.Marker({ icon: profile_img, title: user, map: map, position: myLatLng }); var infowindow = new google.maps.InfoWindow({ content: templates[0].replace('user',user).replace('text',text).replace('url',url).replace('date',date) }); var $tweet = $(templates[1].replace('%user',user).replace(/%profile_img/g,profile_img).replace('%text',text).replace('%url',url)); $('#user-banner').css("visibility","visible");$('#news-banner').css("visibility","visible"); $('#news-tweets').css("overflow","scroll").append($tweet); function openInfoWindow() { infowindow.open(map, marker); } google.maps.event.addListener(marker, 'click', openInfoWindow); $tweet.find(".user").on('click', openInfoWindow); bounds.extend(myLatLng); } }); }

  • Using input type="submit" to change content

    - by Conti
    Okay, I'm pretty sure I'm missing something very obvious here, but I just couldn't find a proper solution so far. What I'm trying to do is simple: Have a user write something into a form, have him submit the form, and write that input into a textarea on the same page. This is my code: <html><head></head> <body> <form name='registration'> <label for="input">Input:</label> <input type="text" id="input"/> <input type="submit" id="submit" value="Submit" onclick="execute()"/> </form> <div id="results"> <span>Result</span> <span><textarea cols="30" rows="5" id="resulttext" readonly="readonly"></textarea> </span> </div> <script> function execute() { var result = document.getElementById("input").value document.getElementById("resulttext").value=result; } </script> </body> </html> Now what happens if I enter something into the form is that the textarea briefly shows my input before reverting back to showing nothing. My guess is that the textarea field is only changed for the duration of the execute() function. When I change input type="submit" to a <button> everything works as intended, but I'm pretty sure I'm not supposed to do that.

  • Getting search results from Twitter in php

    - by Mark Mayo
    I'm attempting to put together a little mashup with some twitter APIs. However, the whole area is new to me (I'm more of an embedded developer dabbling). And frustratingly, every tutorial I am trying in Php is either out of date, not doing what it claims to do, it or is broken. Essentially, I just want a nice bit of example code - say, an HTML file, a connection.js for the JQuery magic, and a php file - 'getsearch' which contains the relevant Curl calls to the API to just return the results for a given search term. Followed the tutorial to the letter at http://www.reynoldsftw.com/2009/02/using-jquery-php-ajax-with-the-twitter-api/ and even downloaded the guy's code and chucked it on my webserver, but it just seems to sit there. I'm relatively competent at php and html, but it's the Curl and the JQuery side of things which is new to me, and would appreciate any thoughts, links, or code suggestions. I've attempted reading the API - but even that seems sparse - and several links are broken to their own tutorials, so that's put me off a bit for now.

  • Elements added with appendTo() not immediately available

    - by Zip Gun Jim
    I'm having a problem with elements added with appendTo() not being immediately available in the DOM. First, I'm reading some data from a JSON file and then appending some html to a div. jsonUrl = "js/performers.json"; $.getJSON(jsonUrl, function(json) { $.each(json.performers, function(i, performer) { var html = '<div class="performer_mini">'; html += '<img src="' + performer.thumbnail + '" alt="' + performer.name + '" /><br />'; html += performer.name + '<br /></div>'; $(html).appendTo("div#performer_spotlight"); }); }); Then I'm calling a random shuffler plugin to show one of the added divs at a time. $("#performer_spotlight").randomShuffler(".performer_mini", 3000, 3000, 9000); The random shuffler does the following: (function($) { $.fn.randomShuffler = function(shuffledElements, fadeInTime, fadeOutTime, timeout) { fadeInTime = fadeInTime || 3000; fadeOutTime = fadeOutTime || 3000; timeout = timeout || 9000; $(shuffledElements).hide(); var $old_element; var $new_element; var old_index = 0; var new_index = 0; function shuffleElement() { $old_element = $new_element; old_index = new_index; while ($(shuffledElements).length > 0 && old_index == new_index) { // don't display the same element twice in a row new_index = Math.floor(Math.random()*$(shuffledElements).length); } $new_element = $(shuffledElements + ":eq(" + new_index + ")"); if ($old_element != undefined) { $old_element.fadeOut(fadeOutTime, function() { $new_element.fadeIn(fadeInTime); }); } else { $new_element.fadeIn(fadeInTime); } setTimeout(shuffleElement, timeout); } $(this).show(); shuffleElement(); } })(jQuery); The first time the shuffleElement() function is called $(shuffledElements).length equals 0, so no element is displayed. On the next call to shuffleElement(), the elements added with appendTo() are available and one is selected at random as expected. Everything works correctly after that. Is there some way to refresh the DOM or make these elements available to jQuery immediately after I add them with appendTo()? Any other suggestions for how to accomplish this?

  • Chrome Extension - Dynamic Right-Click Menu

    - by user1277607
    I am trying to create an option in the right-click menu that is dynamic based on the user's action. If the user selects some text, then right-clicks, the option will say "Display It". If the user right-clicks without selecting some text, the option will say "Select Some Text First" and be grayed out. I am wondering how do I achieve this? I currently have it so that the option will appear only when the user has selected some text. I am unsure how to modify it to meet my second requirements. chrome.contextMenus.create ({ title:"Display It!", contexts:["selection"], onclick:function(info,tab) { chrome.tabs.sendRequest( tab.id, {callFunction: "displaySidebar", info: info}, function(response) {console.log(response);} ); } });

  • element height after content change

    - by Neph
    I have a snippet of code that alters the contents of a DIV to match the contents of a textarea and then applies the height change in the DIV to the textarea element. function growTextArea(parameter) { $('div').find("[data-fieldid='1_description']").text($(parameter).val()); // No Works height = $('.hiddenDiv').find("[data-fieldid='1_description']").outerHeight(); alert(height); // Works heightDiv = $('.hiddenDiv').outerHeight(); alert(heightDiv); $(parameter).css('height', $('div').find("[data-fieldid='1_description']").outerHeight()); } The DIV contents change properly, so the search function is working properly, however the search function always returns the original height of the DIV. The function is called by onKeyUp in the textarea. If the .find is swapped out for a .hiddenDiv the height change is reflected properly.

  • qTip with jQuery dialogs

    - by MikeWyatt
    I'm using qTip to show validation errors in a grid. The tooltip appears after a failed row save and doesn't disappear until the row is resaved or the changes are canceled. The problem with this is that opening a dialog while the tooltip is visible causes the tooltip to be rendered on top of the dialog. That is because the z-index is hard-coded to 6000+ for all tooltips, while jQuery dialogs are set to 1000+. I could fix this problem by changing the hard-coded value in qTip to <1000, but then tooltips fired from the dialog will appear behind the dialog. Is there anything I can do, aside from changing the qTip code or using a different tooltip library?

  • Slow Response in checkbox using JQuery

    - by Dean
    Hi to all. I'm trying to optimize a website. The flow is i tried to query a certain table and all of its data entry in a page(w/ toolbars), work fine. When i tried to edit the page the problem is when i click the checkbox button i have to wait 2-5sec just by clicking it. I limit the viewing of entry to 5 only but the response on checkbox doesn't change. The tables have 100 entries in them. function checkAccess(celDiv,id) { var celValue = $(celDiv).html(); if (celValue==1) $(celDiv).html("<input type='checkbox' value='"+$(celDiv).html()+"' checked disabled>") else $(celDiv).html("<input type='checkbox' value='"+$(celDiv).html()+"' disabled>") $(celDiv).click ( function() { $('input',this).each( function(){ tr_idx = $('#detFlex1 tbody tr').index($(this).parent().parent().parent()); td_idx = $('#detFlex1 tbody tr:eq('+tr_idx+') td').index($(this).parent().parent()); td_last = 13; for(var td=td_idx+1; td<=td_last;td++) { if ($(this).attr('checked') == true) { df[0].rows[tr_idx].cell[td_idx] = 1;//index[1] = Full Access if (td_idx==3) { df[0].rows[tr_idx].cell[td] = 1; } df[0].rows[tr_idx].cell[2] = 1; if (td_idx > 3) { df[0].rows[tr_idx].cell[2] = 1; } } else { df[0].rows[tr_idx].cell[td_idx] = 0;//index[0] = With Access if (td_idx==2) { df[0].rows[tr_idx].cell[td] = 0; } else if (td_idx==3) { df[0].rows[tr_idx].cell[td] = 0; } if (td_idx > 3) { df[0].rows[tr_idx].cell[3] = 0; } } } $('#detFlex1').flexAddData(df[0]); $('.toolbar a[title=Edit Item]').trigger('click'); }); } ); } I've thought that the problem is this above code. Could anyone help me simplify this code.?

  • Print new line in the source-code with jQuery.

    - by Kucebe
    I have a simple function in jQuery that creates new elements in the DOM. the problem is in the html source code, it append every element in the same line, and it's very bad to read. function _loadNewElements(elements){ for(var i=0; i<elements.length; i++){ var fixedElement = $('<img />') var position = elements[i].position; var cssMap = { 'position': 'fixed', 'top': position.top + "px", 'left': position.left + "px" }; fixedElement.css(cssMap); fixedElement.addClass("fixedTag"); fixedElement.attr('alt', elements[i].text); fixedElement.attr('src', "elements/" + elements[i].id + ".png"); fixedElement.appendTo($('#board')); //i'd like to print something here like ("\n"); } } I tried document.write("\n") but in this context it doesn't work. Any solution?

  • Starting an ASP.NET MVC 4 project. Is it necessary to use RequireJS if I'm using bundling?

    - by SCS
    If RequireJS makes it so that multiple js files are combined into a single main.js file, is it essentially the same as ASP.NET's script bundling functionality? Would the only bonus of using RequireJS in addition to bundling be the ability to have certain scripts be loaded according to RequireJS configuration? I'm very new to both bundling and RequireJS, but after doing some reading, it seems like bundling takes care of multiple requests to load several js files. Are there any other things I might be missing out on with regards to using RequireJS with bundling?
