JavaScript - Jslint Doesn't Like This Script.
JSLint doesn't like this script.
Code: document.getElementById('mypic').src=pics[this.number]; if(disc[this.number]!='') { imge=document.createElement('img'); imge.setAttribute('src',disc[this.number]); suggest for line two to use == or === [JavaScript] lint warning: comparisons against null, 0, true, false, or an empty string allowing implicit type conversion (use === or !==) Can anyone help me with this. I am out of my depth. Thanks in advance. Frank Similar TutorialsHere is sampling from a JSLinting of one "core" js file, with some requests for help ... (Btw it runs OK on my machine and is IE only to work with Sketchup web dialogs) Code: Problem at line 15 character 5: 'window' is not defined. window.location = "skp:" + callback + "@" + params.join(';'); This seems very odd to me; surely it cannot be bad! Code: Problem at line 29 character 9: 'nameDown' is not defined. nameDown(params); nameDown is a function in another file; any problem with that? There will be other similar calls. Code: Problem at line 103 character 65: Be careful when making functions within a loop. Consider putting the function in a closure. o.onmousedown = function() { coreDown(this , c , dv ); }; This one is more difficult. Here is the relevant part of the function: Code: // o is a div o.className = p + cn; o.onmousedown = function() { coreDown(this , c , dv ); }; s = o.style; s.width = "100%"; s.height = ch; Is the recommendation relevant, possible? Code: Problem at line 141 character 5: Bad line breaking ... ,interval); in this code (Actually my last thread here) Code: function coreAnimate(obj, elm, begin, end, duration, fps) { var change,interval,steps,i; change = end-begin; interval = Math.ceil(1000/fps); steps = Math.ceil(duration/interval); if(obj.coreStop){ window.clearInterval(obj.coreStop); } i = 0; obj.coreStop = window.setInterval( function() { obj.last = linearTween(i, begin, change, steps); obj.style[elm] = obj.last + 'px'; i+=1; if (i > steps){ window.clearInterval(obj.coreStop); } } ,interval); } It certainly does not look good but is it bad? Code: Problem at line 148 character 14: 'ActiveXObject' is not defined. fs = new ActiveXObject("Scripting.FileSystemObject"); I guess this is the same as window as noted in the last bit of the report: Code: Implied global: window 7,15,130,133,139, nameDown 29, Refresh 63, ActiveXObject 148,162,171 Any help and suggestions gratefully received. Chris I am working on a site and in the process borrowed some js from some one to get dropdown menus to work, but after a while got reports from people who tested my site of some problems and decided to verify all my code, and i have fixed most bugs but the one listed in the title. Code: sfHover = function() { var sfEls = document.getElementById("nav").getElementsByTagName("LI"); for (var i=0; i<sfEls.length; i++) { sfEls[i].onmouseover=function() { this.className+=" sfhover"; }; sfEls[i].onmouseout=function() { this.className=this.className.replace(new RegExp(" sfhover\\b"), ""); }; } }; if (window.attachEvent) {window.attachEvent("onload", sfHover);} and i am verifying it on jslint the error i get is: Quote: Error: Problem at line 6 character 10: Don't make functions within a loop. }; Problem at line 9 character 10: Don't make functions within a loop. }; Implied global: sfHover 1,12, document 2, window 12 any help will be appreciated, and I'm sure this isn't complex but i don't know much js and want to keep it the same. Validator (My CSE HTML Validator v9.0 ) reports javascript errors but program runs. There seems to be a problem with commands used twice and a missing semi-colon. Also there are problems with Firefox. Unable to reselect another image. OK with IE8. I would appreciate it if someone with better eyesight than me could give the jscript a once over for me. Thanks oin advance. Frank Culprit is here. EDITED. Okay I am sure my script is loading when the page loads because of the alert box I have added but when I click on the button that is suppose to activate the script nothing happens. The button code is as follows: <button type="button" name="submit" value="submit" class="css3button" onclick="send(nick,passwd,userid,chan,showtime,showjoin,showpart,showquit,fname,fsize,nnick1,nnick2, nnick3,nnick4,nnick5)">Connect</button> I may be using the button wrong but I am new to javascript. Any suggestions would help. hello... script doesn't work.. it does work in IE but not in another browser like mozilla,opera & safari? what should I do?..

I'm a bit rusty at my javascript. Hi, I am a new poster here and new to javascript as well. I made a script in which if a user enters the correct coupon code, he will be directed to a confirmation page. If not an alert box will say the coupon code was wrong. It sounded simple enough and it worked for sometime. Here is what the code looks like: Code: //in the head section function isGood(elem, helperMsg){ var pass = "x1y2"; if(elem.value==pass){ location.href="./couponbuy.html"; return true;} else{ alert(helperMsg); elem.focus(); return false;} } //in the body section <form> Please Enter Coupon Code: <input type='text' id='code'/> <input type='button' onclick="isGood(document.getElementById('code'), 'Please enter a valid coupon code')" value='Enter' /> </form> As I mentioned, it was working originally, but now it only works when I change the variable 'pass' to something different. I want to be able to keep the variable the same. I don't understand what exactly is going on here. I appreciate any and all help. Thanks. I would like to add a submenu that pops up when the mouse moves over the first-level menu option. I succesfully added the submenu. However, now the image-swap script (the script that makes that the image that you see change as you move your mouse on the image) doesn't work anymore. Does anyone have any idea what I'm doing wrong?

Can someone tell me what I should change to make it work consistently? To sum up, the code detects an image on a server and checks its size. If it's size is less than zero, then "Off" appears in a form input field. Otherwise, "On" appears in the field. This code is being used in a smartphone to test for Internet connection. Code: <form id="formConnection"> <input id="connectionStatus" class="display2" size="1" type="text" name="status" value=""> </form> <!-- testConnectionInApp.png is a 126-byte 10x10px PNG image. --> <script type="text/javascript"> function showOn(form) { form.elements.status.value = "On"; } function showOff(form) { form.elements.status.value = "Off"; } function testConnection() { var checkExistenceOfImg = new Image(); var form = document.getElementById('formConnection'); checkExistenceOfImg.src = "http://aedownloads.com/misc/testConnectionInApp.png"; if(checkExistenceOfImg.height > 0) { showOn(form); } else { showOff(form); } } </script> </body> </html> Hi All, I have two scripts which I want to try and integrate. I am using a nice gallery script to show thumbnails which are appended to a an image wrapper which on click of the thumbnail shows the larger image in the image wrapper, I am trying to implement cloud zoom which is a plugin which uses image srcs to then point to an anchor href to show another larger zoom image either in the same place.. which is what I am trying to do or in another div beside. I have had to set me img srcs up in a certain way to easily enter some product details. and I need to try an manipulate the code to make it work to suit my file layout. I am using a var= images [ with a series of file locations and info such as below { src: 'romanticabride/thumbs/tn_Shauna.jpg', srcBig: 'romanticabride/images/Shauna.jpg', title: 'Shauna', longDescription: '<b><H1>Shauna</H1></b><br><b>Romantica Of Devon <br><br><h2>Sizes Available:</h2><br> 6 - 32.<b><br><b><br><b><b><b><H2>Colours Available:</h2><b><br>Various<br>Please Enquire Below<br><br><br><br><a href="mailto:tracy@cherishbridal.co.uk?subject=Web Enquiry Regarding Romantica Shauna Bridal Gown"class="enquiry rose glow" >Click To Enquire About This Item </a>' }, what I need is for cloud zoom to work when the main image wrapper is hovered over which means it will need to add a class or when the whichever srcBig: is hovered over it gets wrapped by href to make the script work . one of my pages is http://www.cherishbridal.co.uk/romaticabride.html the cloud zoom script is at http://www.professorcloud.com/mainsite/cloud-zoom.htm.. I am happy to share a jsfiddle with someone or explain further or post some code. Thank you in advance I have a script that works in seamonkey(my html editor) but when I use it in IE8 it says errors happen. Here's the code (the first line is on line 7 of the html file): Code: <script type="text/javascript"> function enlarge(imageNum) { var numToString = ""; if(parseInt(imageNum) < 10){ numToString = "0" + imageNum; } else { numToString = imageNum + ""; } window.open("images/LgScreenshot"+numToString+".jpg","Screenshot "+imageNum,"status=0,height=675,width=900,resizable=0"); } </script> And the errors: Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; GTB0.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.30729; InfoPath.3; .NET CLR 3.0.30729) Timestamp: Wed, 10 Feb 2010 14:58:16 UTC Message: Object expected Line: 150 Char: 1 Code: 0 URI: http://samssc2site.co.cc/Features.html Message: Invalid argument.

They're each set to the corresponding id in the JS file. It's supposed to add #tab-1 to the end of the URL in the users browser when it's clicked. For example, when a user is at mypage.com and they click on the tab, it ads mypage.com/#tab-1 to the end. How come it doesn't do what I want when I click it though? Here's an example of how it's setup. HTML: <a href="#tab-1" id="tab1">Text</a> JavaScript: document.getElementById("tab1").onclick = function(){ this.href += "#tab-1"; } Hi! What am doing wrong? The script works -- identifies blank fields -- but the second function (change_subject) is ignored. This is the script: Code: <HEAD> <script> function is_filled() { if (form_1.realname.value=="") { alert("Please enter your name") form_1.realname.focus() return false } if (form_1.subject.value=="") { alert("Please enter a subject") form_1.message.focus() return false } else return true }; function change_subject { form_1.subject.value="form_1.realname.value + '_' + form_1.subject.value" }; </script> </HEAD> This is the FORM (used for MSA FormMail): Code: <form name="form_1"; onSubmit="return is_filled()"; on Submit="change_subject()"; method="post"; action="http://gb2gf.org/cgi-sys/FormMail.cgi"> <input type="hidden" name="recipient" value="drt@gb2gf.org"> <input type="hidden" name="required" value="greeting,realname,city_state,email_1,email_2,message"> <input type="hidden" name="sort" value="order:greeting,realname,city_state,email_1,email_2,message"> <input type="hidden" name="redirect" value="http://www.gb2gf.org/thanks.htm"> <!-- Input fields here --> </form> Thanks! Dr. T. Hi, I've posted a previous thread where the code I had wasn't running. I copied that into the head section and it worked. I'd like to know why it doesn't work in the javascript.js file.
