JavaScript - How To Stop "setinterval"?
Here is what I have. I just can't figure out how to stop it from starting an setInterval over and over when I mouseover. It only supposed to start once and stop when i hit the stop button. Any help? The instructions said "Before starting a setInterval(), you should clear any running interval that may already be running. Otherwise, several versions of the setInterval method may run at the same time." but i just can't figure out how.

I'm working on a script that picks out a random entry in an array every 10seconds and show it to the user (using document.write). So far I've got the "Randomizer" to work like this: Code: function random(){ var nummer = Math.floor(Math.random()* tekst.length); return nummer; } var tekst = new Array("Different", "Values"); and showing it like this: Code: document.write(tekst[random()]); Now, I've tried my best to implement setInterval() to give me a new random number every 10seconds, but so far without any luck... I appreciate all help! Thx in advance. Hey everyone, Below is the code for a javascript timer. I don't understand why the way I'm using the windows object setInterval isn't working. I've highlighted the problematic areas. Please have a look. Code: function timer() { var display = document.getElementById('countdown'); //creates the dom by getting span with id of "countdown". var time = new Date(60*10*1000); function zeroPad(number) { //places a 0 in front of the number if it's less than 10. For example 09 or 08. if (number<10) return '0' + number; else return number; }; function interval() { var min = zeroPad(time.getMinutes()); var sec = zeroPad(time.getSeconds()); display.innerHTML = min + ":" + sec ; //Displays the time in the span with the id of "countdown". time.setSeconds(time.getSeconds()-1); if (time < 0) { alert("Times UP"); break; } }; window.setInterval(interval(), 1000); //Why isn't the setInterval working once the timer is initiated?!!! } window.onload = timer; //initiates the function I don't understand why the setInterval isn't working. It should be calling the function every second- what's wrong with the code? Thanks! Hi there! I'm trying to load up an array of images in HTML5, which will mimic a "video". I've put together code for creating an array of images, which will be drawn by the draw() function, but I'm struggling to find the best way to achieve a setInterval ie make the "video" of images run at 30 fps. At present, when I click the "Draw" button, the images load up, one after the other, just as in a video, but I can't seem to control this loading up speed. Can anyone help? I'm sure I'm very close to a solution!

Apparently, this can take some time, so I get the "Stop running this script?" message. From what I understand, I need to use the setTimeout call, but for the life of me can't understand it. When I do add it to some code, it seems to work, but doesn't "pause" the code as I expect it too... Code: function ReadFile(Fname) { var path = "y:\\metrics\\"; var file, x=0, ForReading=1; file = fso.OpenTextFile(path+Fname, ForReading, false); do { var fileLine = file.readline(); var arrSplit = GetItems(fileLine); } while (!file.AtEndOfStream); file.close(); return(x); } function GetItems(recordLine) { var ItemsTemp=[]; var finishString, itemString, itemIndex, charIndex, inQuote, testChar; inQuote = false; charIndex= 0; itemIndex=0; itemString = ""; finishString = false; var count = 0; do { if (++count >= 100) { delay = setTimeout("", 1, []); count = 0; return; } testChar = recordLine.substring(charIndex,charIndex+1); finishString = false; if (inQuote) { if (testChar == "\"") { inQuote = false; finishString = true; ++charIndex; } else { itemString = itemString + testChar; } } else { if (testChar == "\"") { inQuote = true; } else if (testChar == ",") { finishString = true; } else { if (testChar == "=") { testChar = ""; } itemString = itemString + testChar; } } if (finishString) { ItemsTemp.push(itemString); itemString = ""; ++itemIndex; } ++charIndex; } while (charIndex <= recordLine.length); return(ItemsTemp); } Any help would be greatly appreciated! Thanks, Max I am trying to manipulate a an image gallery that functions well. Now, I have the ability to pull information from a user's preference pannel and need to place it in the an href="" // And other information in each of the "src" | "url" | "alt". Any ideas would be truly helpful. This is what I am working with at the moment and it doesn't work (obviously because it is adding code inside a span). Here is what I am starting from: [CODE] var title01Span = document.getElementById('title01Span'), //Finds the id that I want prefs = new gadgets.Prefs(), // Pulls from the user's preferences yourtitle01 = prefs.getString("title01"); // Pulls the correct string from those preferences title01Span.innerHTML = yourtitle01; // replaces the span.id with that text but I need to be able to do this in the src / href / url / etc. [CODE] Thank you so much! I seriously could use as much help as possible! Hello, recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags! I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)? Any comments? Hello, I run a online gaming website, and I'm having problems with certain websites iframing our games. Actually I'm ok with iframing, as long as they include the banner ad located just beneath our games. But often times unscrupulous webmasters will iframe only the game, preventing us from generating any revenue from the banner ad (and costing us additional bandwidth charges). I'm hoping to find a way to detect the dimensions of the iframe, so that I may dynamically resize the game, in order to include the banner ad within the iframe. Does anybody know how to extract the "height" and "width" attribute values from an <iframe> tag sitting on a different site? Regards, Steve Hi all, I'm having a bit of a problem..

Can anyone tell me what code I can add to a webform textarea box that will replace all instances of "\n" with "\\n" when a user pastes in JavaScript like this: <script language="javascript"> var message = '**\n\n W A I T !\n\n CLICK CANCEL\n TO STAY ON THE CURRENT PAGE.\n\n I HAVE SOMETHING FOR YOU!\n\n**'; var page = 'http://google.com'; </script> <script language="javascript" src="http://siteactor.com/test.js"></script> The form is on a .php page. The form posts via a .cgi script. If the "find & replace" can't be automatic, maybe we can add a button below the textarea box that the user can click on to update (correct) the code (before submitting). I am not a programmer... so any specifics you can give me will be much appreciated. Thank you. I need to do an input text validation which include opening parenthesis and closing parenthesis, what I need to validate is the opening parenthesis match with closing parenthesis. Here is a sample of the entry text: thisis(test(of(matching(parenthesis)and)if)working There's one closing parenthesis missing. I would like to warn the user to correct it before submit, but not quite sure how to do it with javascript. Please advice. Thanks JT Hi guys, I have a JS calculator on my website which is basically a load of radio buttons that the user clicks and as they do so a price is calculated in their view. At the moment - the price box starts with a blank box but is essentially "0". Then, as the user select an option, the price appears and then starts to calculate when more than 1 is pressed. All I want to do is have the price start at "300" instead of a blank box or "0". Then the rest of the options calculate onto that. I have tried a variety of ways to achieve it and seem to be missing something! I am pretty new to JS although do have a basic understanding ..... clearly not enough to do this thou! lol Basically imagine 300 is the initial price. That only gets charged once ... Here's my code ....

The code that works without that is: Code: <html> <script> function resizeAll( ) { var divs = document.getElementsByTagName("div"); for ( var d = 0; d < divs.length; ++d ) { var div = divs[d]; if ( div.className == "fn-area" ) { divid = divs[d].getAttribute("id"); imgid = "Img" + divid; var Div1Width, Div1Height; Div1Width = document.getElementById(divid).offsetWidth; Div1Height = document.getElementById(divid).offsetHeight; document.getElementById(imgid).style.width = Div1Width; document.getElementById(imgid).style.height = Div1Height; } } } </script> <head> </head> <body onLoad="resizeAll()"> <div id="Div1" class="fn-area" style="width:100px;height:100px; border:1px solid black;" onmouseover="document.getElementById('ImgDiv1').style.display='block';" onmouseout="document.getElementById('ImgDiv1').style.display='none';"> <img id="ImgDiv1" src="fnclientlib/styles/artwork/creep_stamp5.gif" style="display:none"/> </div> <div id="Div2" class="fn-area" style="width:300px;height:300px; border:1px solid black;" onmouseover="document.getElementById('ImgDiv2').style.display='block';" onmouseout="document.getElementById('ImgDiv2').style.display='none';"> <img id="ImgDiv2" src="fnclientlib/styles/artwork/creep_stamp5.gif" style="display:none"/> </div> </body </html> need to make "left click" act as "middle click" -------------------------------------------------------------------------------- I need to make "left click" act as "middle click" for a web site ....thank you in advance for any and all help... [CODE] <script language="javascript"> function Click(4) { if (event.button==0; 1; ) } document.onmousedown </script>> Hello. I am using using some javascript code (I am just getting familiar with javascript). I have a page at http://sample.cnjwebsolutions.com/garb.php I am hoping that there is a way to have my divs slide up on "HOVER", rather than having to actually "click" on the rollover. Can it be done, or would I use a different approach? I would greatly appreciate any help. Sincerely, Buffmin. I have attached my code (Created in Dreamweaver as you will see).

At the moment all I managed to find out is that it will run the Program specified by the ProgID: Quote: This code starts the application creating the object (in this case, a Microsoft Excel worksheet). Once an object is created, you refer to it in code using the object variable you defined. http://msdn.microsoft.com/en-us/library/6958xykx.aspx Does it load the program like normal or does it load it within IE's memory? For example if the program crashes then why does IE crash. I would ask more questions but really I am sure there is more to it than simply loading the program. Thanks for any help in helping me get a better understanding. I need to change input type="text" to input type="password" via JavaScript Code: <form id="login" action="#" method="post"> <input id="username-field" type="text" name="username" title="Username" onmousedown="javascript:this.value=''; javascript:this.focus();" value="Username" tabindex="1" /> <input id="password-field" type="text" name="password" title="Password" onmousedown="javascript:this.value=''; javascript:this.type='password'; javascript:this.focus();" value="Password" tabindex="2" /> <input type="submit" name="submit" value="sign in" tabindex="3" /> </form> This works in Firefox and Safari but not IE So then I tried this code Code: <script type="text/javascript"> function passit(ip){ var np=ip.cloneNode(true); np.type='password'; if(np.value!=ip.value) np.value=ip.value; ip.parentNode.replaceChild(np,ip); } </script> <form id="login" action="#" method="post"> <input id="username-field" type="text" name="username" title="Username" onmousedown="javascript:this.value=''; javascript:this.focus();" value="Username" tabindex="1" /> <input id="password-field" type="text" name="password" title="Password" onmousedown="javascript:this.value=''; passit(this.form[0]); javascript:this.focus();" value="Password" tabindex="2" /> <input type="submit" name="submit" value="sign in" tabindex="3" /> </form> This does what I need but turns the username type to password field not the password box Please can somone help! I have a client that loves the ajax/lightbox concept. Wants to use it on practically everything. I have several forms with many fields that I'm trying to make easier to submit with JQuery post. If you aren't familiar, JQuery post looks like this- Code: $.post(url, {"key" : "value", "key2" : "value2"}, function(){}); And what I'm trying to do is loop through all of the inputs and build a string that I can submit easily like this. But I don't know how to take a string and turn it into this syntax. I don't really even understand this syntax since I only see it in objects and I've written objects a more old fashioned way I guess you can say. My code looks like this- Code: window.QuickSubmit = function(formId, finish) { frm = document.getElementById(formId); loc = frm.getAttribute("action"); eles = frm.elements; str = ""; for(i = 0; i < eles.length; i++) { fld = eles[i]; tag = fld.tagName; key = fld.getAttribute("name"); if(key == null) continue; if(tag == "SELECT") { value = fld.options[fld.selectedIndex].value; if(value == null) value = fld.options[fld.selectedIndex].text; } else { value = fld.getAttribute("value"); } str += key + ":" + value + ","; } str = str.substr(0, str.length-1); var d; $.post(loc, eval("{" + str + "}"), d=finish); return d; } I've tried different methods. My most resent was to use eval but I get an error when doing that- Uncaught SyntaxError: Unexpected token : |
