  • Scroll an input box to the cursor position in javascript

    - by sirlark
    I've written a simple JS function that places the cursor at the end of the contents of an input box when it receives focus (the most common action in the box being to append). I haven't checked in IE, but when there is more text than is visible, even moving the cursor to the end of input doesn't scroll the view to the end of input in firefox 3.6. Any idea how to do this? P.S. And no I'm not using JQuery, nor is it an option ;)

  • Display real time years, months, weeks and days between 2 days in JavaScript

    - by alex
    This is what I've coded it up, and it appears to work. window.onload = function() { var currentSpan = document.getElementById('current'); var minute = 60000, hour = minute * 60, day = hour * 24, week = day * 7, month = week * 4, year = day * 365; var start = new Date(2009, 6, 1); setInterval(function() { var now = new Date(); var difference = now - start; var years = Math.floor(difference / year), months = Math.floor((difference - (years * year)) / month), weeks = Math.floor((difference - (months * month + years * year)) / week), days = Math.floor((difference - (weeks * week + months * month + years * year)) / day); currentSpan.innerHTML = 'Since has passed: ' + years + ' years, ' + months + ' months, ' + weeks + ' weeks and ' + days + ' days'; }, 500); }; This seems to update my span fine, and all the numbers look correct. However, the code looks quite ugly. Do I really need to set up faux constants like that, and then do all that math to calculate what I want? It's been a while since I've worked with the Date object. Is this the best way to do this?

  • Create your own HTML Textfield with Javascript

    - by teehoo
    I came across the following http://ckeditor.com/demo , and was wondering if anyone had a basic tutorial how to implement this (or perhaps what key search terms I should use)? Is this just a heavily modified TextField, or have they somehow managed to create a completely new TextField from scratch? I tried googling this many times, and I always get pages relating to customizing the built-in TextField with CSS etc.

  • Building a Hashtag in Javascript without matching Anchor Names, BBCode or Escaped Characters

    - by Martindale
    I would like to convert any instances of a hashtag in a String into a linked URL: #hashtag - should have "#hashtag" linked. This is a #hashtag - should have "#hashtag" linked. This is a [url=http://www.mysite.com/#name]named anchor[/url] - should not be linked. This isn&#39;t a pretty way to use quotes - should not be linked. Here is my current code: String.prototype.parseHashtag = function() { return this.replace(/[^&][#]+[A-Za-z0-9-_]+(?!])/, function(t) { var tag = t.replace("#","") return t.link("http://www.mysite.com/tag/"+tag); }); }; Currently, this appears to fix escaped characters (by excluding matches with the amperstand), handles named anchors, but it doesn't link the #hashtag if it's the first thing in the message, and it seems to grab include the 1-2 characters prior to the "#" in the link. Halp!

  • How to identify HTML elements (in javascript) in a browser agnostic fashion

    - by gatapia
    Hi All, I need to identify all html elements on a page in a browser agnostic fashion. What I am basically doing is using mouse events to record clicks on the page. I need to record which element was clicked. So I add a mouse down listener to the document.body element. And on mouse down I get the element under the mouse. Lets say its a div. I then use the index of that div inside the document.getElementsByTagName('*') nodelist and the nodeName ('div') to identify that div. A sample element id would be div45 which means its a div and its the 45th element in the '*' nodelist. This is all fine and good until I use IE which gives me different indexes. So div45 in FireFox may be div47 in IE. Anyone have any ideas? I just need the id of all elements on the page to be the same in any browser, perhaps indexing is not good enough but I really don't have any more ideas. Thanks Guido

  • JavaScript problems in one IIS server but not another

    - by DanyW
    Hi everyone, I have a problem that only occurs in one environment. On this particular page, somewhere in the top half of the element, an array is created and populated. This is later used in the onfocus event handlers of various controls. I use Firebug to debug the page and discovered the problem. In our dev environment the array is indeed created and populated. In our staging environment this block of script is not executed! I put a break point where the array is instantiated and it's never hit in staging, but is hit in dev. I'm really puzzled what aspects of the two environments can possibly affect this? We use aptimize on the staging box but it has been turned off for this particular website. I compared the page sources and they're identical! The only difference is bits of content since they are served by a CMS. Any ideas please? I'm quite stuck on this. Cheers, Dany.

  • Parse 2 dimensional JSON array in Javascript

    - by MrG
    I have a two dimensional JSON array where each element contains several attributes. The example below is intentionally simplified: var map_data = { "1": {"1":{"name":"aa"},"2":{"name":"bb"}}, "2": {"1":{"name":"cc"},"2":{"name":"dd"}} }; I try to parse the data but .length doesn't work: for(x=1; x<=map_data.length; x++) { for(y=1; y<=map_data[x].length; y++) { // CODE } } Many, many thanks!

  • What's wrong with this javascript?

    - by Arlen Beiler
    What's wrong with this code? var divarray = document.getElementById("yui-main").getElementsByTagName("div"); var articleHTML = array(); var absHTML; var keyHTML; var bodyHTML = array(); var i = 0; for ( var j in divarray) { if(divarray[i].className == "articleBody"){ alert("found"); articleHTML = divarray[i]; break; } bodyHTML[i] = ''; if(articleHTML[i].className == "issueMiniFeature"){continue;} if(articleHTML[i].className == "abstract"){absHTML = articleHTML[i]; continue;} if(articleHTML[i].className == "journalKeywords"){keyHTML = articleHTML[i]; continue;} bodyHTML[i] = articleHTML[i]; i++; } This is the error I am getting: ReferenceError: array is not defined I am using Google Chrome if it helps any.

  • "Disabling" an HTML table with javascript

    - by Blair Jones
    I've seen this done in a lot of sites recently, but can't seem to track one down. Essentially I want to "disable" an entire panel (that's in the form on an HTML table) when a button is clicked. By disable I mean I don't want the form elements within the table to be usable and I want the table to sort of fade out. I've been able to accomplish this by putting a "veil" over the table with an absolutely positioned div that has a white background with a low opacity (so you can see the table behind it, but can't click anything because the div is in front of it). This also adds the faded effect that I want. However, when I set the height of the veil to 100% it only goes to the size of my screen (not including the scrolling), so if a user scrolls up or down, they see the edge of the veil and that's not pretty. I'm assuming this is typically done in a different fashion. Does anyone have some suggestions as a better way to accomplish this?

  • Compare only date javascript

    - by moleculezz
    Hi all, I can't seem to figure out what is wrong with my code. Maybe it would be simpler to just compare date and not time. Not sure how to do this either and I searched but couldn't find my exact problem. BTW, when I display the two dates in an alert, they show as exactly the same. My code: window.addEvent('domready', function() { var now = new Date(); var input = $('datum').getValue(); var dateArray = input.split('/'); var userMonth = parseInt(dateArray[1])-1; var userDate = new Date(); userDate.setFullYear(dateArray[2], userMonth, dateArray[0], now.getHours(), now.getMinutes(), now.getSeconds(), now.getMilliseconds()); if(userDate > now) { alert(now+'\n'+userDate); } }); Perhaps there is a simpler way to compare dates and not including the time. Hope someone has an answer... Thanks!

  • Passing additional arguments into the OnClick event handler of a LinkButton using Javascript

    - by Jens Ameskamp
    Hi! I have a ASP.NET Website, where, in a GridView item template, automatically populated by a LinqDataSource, there is a LinkButton defined as follows: <asp:LinkButton ID="RemoveLinkButton" runat="server" CommandName="Remove" CommandArgument='<%# DataBinder.GetPropertyValue(GetDataItem(), "Id")%>' OnCommand="removeVeto_OnClick" OnClientClick='return confirm("Are you sure?");' Text="Remove Entry" /> This works fine. Whenever the Button is Clicked, a confirmation dialog is displayed. What I am trying to do now, is to allow the user to enter a reason for the removal, and pass this on the the OnClick event handler. How would I do this? I tried OnClientClick='return prompt("Enter your reason!");', but, of course, that did not work =)

  • Javascript, language files, configuration

    - by johnnyArt
    I'm building a form validation script for one of my sites, and I thought I'd make the error messages international, meaning that depending on the users language I'd give such or such response. What would the best approach be, for loading a configuration file inside of my class? Right now I'm using the following structure for a single language: const config = { 'errorName' : 'error message', 'errorName2' : 'error message', 'errorName2' : 'error message' } And calling it like this of course: config['errorName']. But I don't know how to load those variables from a file, let's say 'lang/en.js'

  • Update time descriptions every minute using jquery/javascript

    - by Amy Neville
    I have created the following code to update the text contents of all spans like this every minute. There are numerous of these spans on the page which all need to be updated every minute: <span unix="1372263005" class="time_ago">4 minutes ago</span> The code is as follows: window.setInterval(function(){ var unix = $(".time_ago").text(); var now = new Date().getTime(); var amount = 0; var difference = 0; difference = now - parseInt(unix); if (difference < 60) { $(".time_ago").text('<span unix="' + unix + '" class="time_ago">a few seconds ago</span>'); } else if (difference < 120) { $(".time_ago").text('<span unix="' + unix + '" class="time_ago">a minute ago</span>'); } else if (difference < 3600) { amount = floor(difference / 60); $(".time_ago").text('<span unix="' + unix + '" class="time_ago">' + amount + ' minutes ago</span>'); } else if (difference < 7200) { $(".time_ago").text('<span unix="' + unix + '" class="time_ago">an hour ago</span>'); } else if (difference < 86400) { amount = floor(difference / 3600); $(".time_ago").text('<span unix="' + unix + '" class="time_ago">' + amount + ' hours ago</span>'); } else if (difference < 172800) { $(".time_ago").text('<span unix="' + unix + '" class="time_ago">a day ago</span>'); } else if (difference < 2635200) { amount = floor(difference / 86400); $(".time_ago").text('<span unix="' + unix + '" class="time_ago">' + amount + ' days ago</span>'); } else if (difference < 5270400) { $(".time_ago").text('<span unix="' + unix + '" class="time_ago">a month ago</span>'); } else if (difference < 31622400) { amount = floor(difference / 2635200); $(".time_ago").text('<span unix="' + unix + '" class="time_ago">' + amount + ' months ago</span>'); } else if (difference < 63244800) { $(".time_ago").text('<span unix="' + unix + '" class="time_ago">a year ago</span>'); } else (difference >= 63244800) { amount = floor(difference / 31622400); $(".time_ago").text('<span unix="' + unix + '" class="time_ago">' + amount + ' years ago</span>'); } return false; }, 60); EDIT) Ok, now I have made some changes on your advice but it's changing the span texts to 43351 years. Any ideas why it is doing that?

I have loop for (i=0;i<15;i++){ Timeline.loadXML(function_that_return_url(), function(xml, url) { eventSource[i].loadXML(xml, url); }); } This code is for Timeline.loadXML: Timeline.loadXML = function(url, f) { var fError = function(statusText, status, xmlhttp) { alert("Failed to load data xml from " + url + "\n" + statusText); }; var fDone = function(xmlhttp) { var xml = xmlhttp.responseXML; if (!xml.documentElement && xmlhttp.responseStream) { xml.load(xmlhttp.responseStream); } f(xml, url); }; SimileAjax.XmlHttp.get(url, fError, fDone);}; When I open the page - my function function(xml, url) { eventSource[i].loadXML(xml, url); }); is passed to loadXML method which use it inside as f(xml, url); Problem is that i variable is not parsed as number and I receive message that eventSource[...] is not declared.

  • Dynamically adding values to a form with JQuery/Javascript

    - by bigstylee
    I am creating a private message system to allow users to communicate between one another within the context of the website (ie, not emails). I have created this function to handle all my form submissions. I would like to achieve a solution without modifying this function (ideally). $("form.reload").submit(function(){ alert($(this).serialize()); /* Debugging */ $.post($(this).attr("action"), $(this).serialize() ,function(data){ if(data){ $("#error").html(data); }else{ location.reload(); }; }); return false; }); Within my form I am using JQuery Autocomplete to find usernames. This function works perfectly. My first solution was to add buttons within the form with the necessary values. select: function(event, ui) { $("#message_to").append("<input type=\"button\" class=\"recipient\" name=\"recipients[]\" value=\"" + ui.item.label + "\" onclick=\"$(this).remove()\" />"); } <form method="post" action="/messages-create"> <div id="message_to"></div> </div> For some reason the values of recipients are not getting posted. My second solution was to add to a post array that already existed in the form select: function(event, ui) { $(input[name=recipeients[]).val = ui.item.label; /* Need to add to array, not replace! */ $("#message_to").append("<input type=\"button\" class=\"recipient\" name=\"recipient\" value=\"" + ui.item.label + "\" onclick=\"$(this).remove(); /* Remove from recipients */\" />"); } <form method="post" action="/messages-create" class="reload"> <input type="hidden" name="recipients[]" value="" /> <div id="message_to"></div> </div> This works ok, but I have been unable to work out how to append to the recipients[] array only replace with the new label. Moving on from this, I also need to know how to then remove this value from the array. Thanks in advance!

  • Find Line Above or Below in Javascript

    - by Dark Falcon
    I am working on an in-place HTML editor, concentrating on Firefox only right now. I have an element inserted where the cursor should be and also have left and right arrows working, but I can't seem to find a way to find: Start and end of a line for the home and end keys The next line up or down for the up/down arrows. I see document.elementFromPoint, but this doesn't get me a Range object. The Range object itself seems rather useless when it comes to using pixel positions.

  • Scoping inside Javascript anonymous functions

    - by DCD
    I am trying to make a function return data from an ajax call that I can then use. The issue is the function itself is called by many objects, e.g.: function ajax_submit (obj) { var id = $(obj).attr('id'); var message = escape ($("#"+id+" .s_post").val ()); var submit_string = "action=post_message&message="+message; $.ajax({ type: "POST", url: document.location, data: submit_string, success: function(html, obj) { alert (html); } }); return false; } Which means that inside the anonymous 'success' function I have no way of knowing what the calling obj (or id) actually are. The only way I can think of doing it is to attach id to document but that just seems a bit too crude. Is there another way of doing this?

  • small javascript problem

    Hi, I have this little function that opens modal window type thing. The problem is that it doesnt work on IE. All other browser its fine, but on IE, nothing happends: function showOverlayBox() { if( isOpen == false ) return; $('#full').css({ display:'block', left: ( $(window).width() - $('#full').width() )/2, top: ( $(window).height() - $('#full').height() )/2, position:'absolute' }); $('.BgCover').css({ display:'block', width: $(window).width(), height: $(window).height() }); } function doOverlayOpen() { isOpen = true; showOverlayBox(); $('.BgCover').css({opacity:0}).animate( {opacity:0.8} ); return false; } function doOverlayClose() { $('#full').css( 'display', 'none' ); $('.BgCover').animate( {opacity:0}, null, null, function() { $(this).hide(); } ); } Maybe something to do with isOpen == false?
