  • Invert a string: Recursion vs iteration in javascript

    - by steweb
    Hi all, one month ago I've been interviewed by some google PTO members. One of the questions was: Invert a string recursively in js and explain the running time by big O notation this was my solution: function invert(s){ return (s.length > 1) ? s.charAt(s.length-1)+invert(s.substring(0,s.length-1)) : s; } Pretty simple, I think. And, about the big-o notation, I quickly answered O(n) as the running time depends linearly on the input. - Silence - and then, he asked me, what are the differences in terms of running time if you implement it by iteration? I replied that sometimes the compiler "translate" the recursion into iteration (some programming language course memories) so there are no differences about iteration and recursion in this case. Btw since I had no feedback about this particular question, and the interviewer didn't answer "ok" or "nope", I'd like to know if you maybe agree with me or if you can explain me whether there could be differences about the 2 kind of implementations. Thanks a lot and Regards!

  • Stupid problem with Javascript calculations and postbacks

    - by rockinthesixstring
    I'm working on an ASP.NET web app where I'm using a Wizard to take the client through a large series of steps. One of the steps includes calculating a bunch of numbers on the fly... the numbers calculate properly but when I click "next" and then go back again... some of the numbers are not retained. Here is the calculation function function CalculateFields() { txtSellingPrice = document.getElementById('<%=txtSellingPrice.ClientID %>'); txtBalanceSheet = document.getElementById('<%=txtBalanceSheet.ClientID %>'); txtDownPayment = document.getElementById('<%=txtDownPayment.ClientID %>'); txtSusEarn = document.getElementById('<%=txtSusEarn.ClientID %>'); txtSusRev = document.getElementById('<%=txtSusRev.ClientID %>'); txtBalanceMult = document.getElementById('<%=txtBalanceMult.ClientID %>'); txtGoodwillMult = document.getElementById('<%=txtGoodwillMult.ClientID %>'); txtSellingPriceMult = document.getElementById('<%=txtSellingPriceMult.ClientID %>'); txtGoodWill = document.getElementById('<%=txtGoodWill.ClientID %>'); txtBalance = document.getElementById('<%=txtBalance.ClientID %>'); chkTakeBack = document.getElementById('<%=chkTakeBack.ClientID %>'); txtVendorTakeBackPercentage = document.getElementById('<%=txtVendorTakeBackPercentage.ClientID %>'); txtSusEarnPercentage = document.getElementById('<%=txtSusEarnPercentage.ClientID %>'); txtBalanceMultPercentage = document.getElementById('<%=txtBalanceMultPercentage.ClientID %>'); txtGoodwillMultPercentage = document.getElementById('<%=txtGoodwillMultPercentage.ClientID %>'); txtSellingPriceMultPercentage = document.getElementById('<%=txtSellingPriceMultPercentage.ClientID %>'); var regexp = /[$,]/g; //Empty value checks SellingPrice = (SellingPrice == "" ? "$0" : SellingPrice); BalanceSheet = (BalanceSheet == "" ? "$0" : BalanceSheet); DownPayment = (DownPayment == "" ? "$0" : DownPayment); susearn = (susearn == "" ? "$0" : susearn); susrev = (susrev == "" ? "$0" : susrev); balmult = (balmult == "" ? "$0" : balmult); goodmult = (goodmult == "" ? "$0" : goodmult); sellmult = (sellmult == "" ? "$0" : sellmult); //Replace $ with String.Empty SellingPrice = txtSellingPrice.value.replace(regexp, ""); BalanceSheet = txtBalanceSheet.value.replace(regexp, ""); DownPayment = txtDownPayment.value.replace(regexp, ""); susearn = txtSusEarn.value.replace(regexp, ""); susrev = txtSusRev.value.replace(regexp, ""); balmult = txtBalanceMult.value.replace(regexp, ""); goodmult = txtGoodwillMult.value.replace(regexp, ""); sellmult = txtSellingPriceMult.value.replace(regexp, ""); //Set the new values txtGoodWill.value = "$" + (SellingPrice - BalanceSheet); txtBalance.value = "$" + (SellingPrice - DownPayment); txtSellingPriceMult.value = "$" + SellingPrice; txtGoodwillMult.value = "$" + (SellingPrice - BalanceSheet); txtBalanceMult.value = "$" + BalanceSheet; if (chkTakeBack.checked == 1) { txtVendorTakeBackPercentage.value = Math.round((SellingPrice - DownPayment) / SellingPrice * 100); } else { txtVendorTakeBackPercentage.value = "0"; } if (!(susearn == "") && !(susearn == "0") && !(susearn == "$0")) { txtSusEarnPercentage.value = Math.round(susearn / susrev * 100); txtBalanceMultPercentage.value = Math.round(balmult / susearn); txtGoodwillMultPercentage.value = Math.round(goodmult / susearn); txtSellingPriceMultPercentage.value = Math.round(sellmult / susearn); } else { txtSusEarnPercentage.value = "0"; txtBalanceMultPercentage.value = "0"; txtGoodwillMultPercentage.value = "0"; txtSellingPriceMultPercentage.value = "0"; } } all of these calculate properly and retain their value across postbacks txtGoodWill.value = "$" + (SellingPrice - BalanceSheet); txtBalance.value = "$" + (SellingPrice - DownPayment); txtSellingPriceMult.value = "$" + SellingPrice; txtGoodwillMult.value = "$" + (SellingPrice - BalanceSheet); txtBalanceMult.value = "$" + BalanceSheet; These ones however do not retain their value across postbacks if (chkTakeBack.checked == 1) { txtVendorTakeBackPercentage.value = Math.round((SellingPrice - DownPayment) / SellingPrice * 100); } else { txtVendorTakeBackPercentage.value = "0"; } if (!(susearn == "") && !(susearn == "0") && !(susearn == "$0")) { txtSusEarnPercentage.value = Math.round(susearn / susrev * 100); txtBalanceMultPercentage.value = Math.round(balmult / susearn); txtGoodwillMultPercentage.value = Math.round(goodmult / susearn); txtSellingPriceMultPercentage.value = Math.round(sellmult / susearn); } else { txtSusEarnPercentage.value = "0"; txtBalanceMultPercentage.value = "0"; txtGoodwillMultPercentage.value = "0"; txtSellingPriceMultPercentage.value = "0"; } The txtVendorTakeBackPercentage always comes back BLANK and the other three always come back as 0 I'm firing these functions by using the onkeyup event within the form fields. If Not Page.IsPostBack Then txtSellingPrice.Attributes.Add("onkeyup", "CalculateFields()") txtBalanceSheet.Attributes.Add("onkeyup", "CalculateFields()") txtDownPayment.Attributes.Add("onkeyup", "CalculateFields()") txtSusRev.Attributes.Add("onkeyup", "CalculateFields()") txtSusEarn.Attributes.Add("onkeyup", "CalculateFields()") End If any thoughts/help/direction would be greatly appreciated.

  • How to update document object value in loop (Javascript)

    - by Graham
    Hi folks i am a beginer to Java script so appologies if this is a dumb question. I am trying to put the following in a for loop but I can't seem to get it to work. if (rowID==1) { document.form1.class_titleDis_1.value=class_title; } if (rowID==2) { document.form1.class_titleDis_2.value=class_title; } This is what I tried var i=1; for (i=1;i<=2;i++) { document.form1.(class_titleDis_)+i.value=class_title; } I would be really grateful for any suggestions.

  • Using a Javascript Variable & Sending to JSON

    - by D Franks
    Hello all! I'm trying to take a URL's hash value, send it through a function, turn that value into an object, but ultimately send the value to JSON. I have the following setup: function content(cur){ var mycur = $H(cur); var pars = "p="+mycur.toJSON(); new Ajax.Updater('my_box', 'test.php', { parameters: pars }); } function update(){ if(window.location.hash.length > 0){ content(window.location.hash.substr(1)); // Everything after the '#' } } var curHashVal = window.location.hash; window.onload = function(){ setInterval(function(){ if(curHashVal != window.location.hash){ update(); curHashVal = window.location.hash; } },1); } But for some reason, I can't seem to get the right JSON output. It will either return as a very large object (1:"{",2:"k") or not return at all. I doubt that it is impossible to accomplish, but I've exhausted most of the ways I can think of. Other ways I've tried were "{" + cur + "}" as well as cur.toObject(), however, none seemed to get the job done. Thanks for the help!

  • javascript setTimeout function out of scope.

    - by Keyo
    I am trying to call showUpload(); from within two setTimeouts. Neither works. It seems to be out of scope and I'm not sure why. I tried this.showUpload() which didn't work either. $(document).ready(function(){ var progress_key = $('#progress_key').val(); // this sets up the progress bar $('#uploadform').submit(function() { setTimeout("showUpload()",1500); $("#progressbar").progressbar({ value:0}).fadeIn(); }); // uses ajax to poll the uploadprogress.php page with the id // deserializes the json string, and computes the percentage (integer) // update the jQuery progress bar // sets a timer for the next poll in 750ms function showUpload() { $.get("/myid/videos/uploadprogress/" + progress_key, function(data) { if (!data) return; var response; eval ("response = " + data); if (!response) return; var percentage = Math.floor(100 * parseInt(response['bytes_uploaded']) / parseInt(response['bytes_total'])); $("#progressbar").progressbar({ value:percentage}) }); setTimeout("showUpload()", 750); } }); Thank you for your time.

  • 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!

  • Determining when scrolled to bottom of a page with Javascript

    - by chimerical
    I'm trying to determine when I've scrolled to the bottom of the page (without using any JS library), but so far, I'm a bit confused over which one of the following to use. The most promising one I've seen is window.scrollY, but even when scrolled to the bottom of the page, it never matches the value of window.innerHeight. What's the best way to do this? window.innerWidth window.innerHeight window.outerWidth window.outerHeight window.scrollX window.scrollY document.body.scrollWidth document.body.scrollHeight document.body.scrollTop document.body.scrollLeft document.body.offsetTop document.body.offsetLeft document.body.offsetWidth document.body.offsetHeight

  • JavaScript Resource Management Design Pattern

    - by Adam
    As a web developer, a common problem I find myself tackling is waiting for something to load before doing something else. In particular, I often hide (using either display: none; or visibility: hidden; depending on the situation) elements while waiting for a background image or a CSS file to load. Consider this example from Last.FM. They overlay a semi-transparant PNG over each album art image so that it looks like it's inside a jewel-case. They let it load when it loads, so depending on your internet speed, you may see the art image by itself (without the overlay) temporarily. In this case, the album art looks fine without the jewel-case effect. But in similar situations, I have found that I don't want the user to see the site's design mangled as resources incrementally load. So, in rare cases I have hidden everything from the user until the whole kit and kaboodle has loaded. But this is often a pain to write out, and may force the user to wait for a pretty long time to see anything (besides "loading..." text). I can think of (and have used on occasion) some obvious solutions/compromises: Use some inline CSS so that as certain parts of the DOM load and render, they will immediately have the correct size/position/etc. Immediately render the navigation part of the site, so that if the user wanted to use the current page purely to get somewhere else, they don't have to wait for the rest to load. Load pixelated images first as placeholders for layout while lazy-loading higher quality images as replacements. Something quirky like using a cute animated gif to distract the user during a "loading..." phase. Show useful information as a reference while loading the full UI. (Something akin to Gmail Inbox Preview, etc.) (Sorry if my question was basically just asked and answered...) Despite all of these ideas, I still find myself hoping there are better ways of doing some of these things. So I guess what I'm looking for is some inspiration and/or any creative ways of dealing with this problem that you guys may have seen out in the wild.

  • JavaScript: count minimal length of characters in text, ignoring special codes inside

    - by ilnur777
    I want to ignore counting the length of characters in the text if there are special codes inside in textarea. I mean not to count the special codes characters in the text. I use special codes to define inputing smileys in the text. I want to count only the length of the text ignoring special code. Here is my approximate code I tried to write, but can't let it work: // smileys // ======= function smileys(){ var smile = new Array(); smile[0] = "[:rolleyes:]"; smile[1] = "[:D]"; smile[2] = "[:blink:]"; smile[3] = "[:unsure:]"; smile[4] = "[8)]"; smile[5] = "[:-x]"; return(smile); } // symbols length limitation // ========================= function minSymbols(field){ var get_smile = smileys(); var text = field.value; for(var i=0; i<get_smile.length; i++){ for(var j=0; j<(text.length); j++){ if(get_smile[i]==text[j]){ text = field.value.replace(get_smile[i],""); } } } if(text.length < 50){ document.getElementById("saveB").disabled=true; } else { document.getElementById("saveB").disabled=false; } } How the script should be in order to let it work? Thank you!

  • Overriding previously set float using javascript in ie

    - by wheresrhys
    I've read this question to figure out how to set float:none on an element which already has float:right set with class. I used element.style.cssFloat = "none", but this just added a new style property cssFloat which didn't over-ride the existing float:right. I've now fixed it using the adding/removing classes method. But is there a way of over-riding existing float rules in ie without having to use classes?

  • Iterating thorough JSON with jQuery/Javascript

    I am trying to fill a table with JSON data. When I run the following script I get only the last entry of 10. I must have to do some sort of .append() or something.

  • 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.

  • Storing DOM reference elements in a Javascript array

    - by webzide
    Dear experts, I was trying to dynamically generate DOM elements using JS. I read from Douglas Crockford's book that DOM is very very poorly structured. Anyways, I would like to create a number of DIVISION elements and store the reference into an array so it could be accessed later. Here's the code for(i=0;i<3;i++){ var div=document.body.appendChild(document.createElement("div")); var arr=new Array(); arr.push(div); } Somehow this would not work..... There is only 1 div element created. When I use the arr.length to test the code there is only 1 element in the array. Is there another way to accomplish this? Thanks in advance

  • How to specify a font from javascript?

    - by Steven Lu
    I am trying to customize a view-src bookmarklet for iPad. This one is looking pretty good so far. But I want to make it just a little more readable: The Courier (New) font is a bit ugly even (especially?) on the retina display and I'd prefer any one of DejaVu Sans Mono, Monaco, Lucida Console, Bitstream Vera Sans Mono. I tried to modify the bookmarklet script by adding: pre.style.fontFamily = '"DejaVu Sans Mono", "Lucida Console", Monaco;'; It's not doing the trick. Perhaps prettyprint cancels out my fontFamily setting when it loads. Maybe I can set it at the end of the script somehow...
