JavaScript - Assistance With Confirm And Return
Hi Guys,
I would like to add a confirmation to this: PHP Code: echo "<a href=\"delete.php?dir=$dir&file=$file\" onclick='return del(this, \"$id\")'><img src=\"images/delete.gif\" border=\"0\" /></a>"; However I seem to be struggling, severely! Any help would be greatly appreciated, especially if spelt out if alphabetti spaghetti. Kind Regards, Drew Similar TutorialsI don't understand the logic of Break, Return False, Return True. It was never really covered in our college class, and I see everyone using it. I got an A in the class, if that 'proves' that I really tried to apply myself. NOTE: I understand what the function is doing. I just don't understand WHEN to use break, return false or return true if the the translator can determine the conditional statements. PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } else return false; } if the the translator can determine the conditional statements, why not write it like this: PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; // what's the point for the 'break'? Won't the rest of the code be ignored since it passed the first condition? } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } // why not leave the last else out? is it just a 'safety' catch, in case something other than true or false is inputted? else return false; // what's the point? } Questions: Why use return true, if the translator knows it's ture? Why use "return false" if the translator knows it's false and the alert window has already gone up? why not use "break" to stop the code? Why use the "return false" at the end "else" statement? Hi room, Hey, I opened up the source code for this page in google chrome and since i'm learning javascript, i wanted see if i could "read" it and figure out what was going on. I'm am having the hardest time understanding "return false" and "return true". Could someone step me through this via interpreting this code (in bold typeface): Code: var DefaultValue = 'Search'; function clearSearch() { if (document.searchForm.q.value == DefaultValue) { document.searchForm.q.value = ''; } } function validateSearchHeader() { if ( document.searchForm.q.value == '' || document.searchForm.q.value.toLocaleLowerCase() == DefaultValue.toLocaleLowerCase() ) { alert('Please enter at least one keyword in the Search box.'); document.searchForm.q.focus(); return false; } return true; } Thanks! Hi, I am trying to give the user the option of music on my homepage (b/c we've all found it annoying at times...perhaps most times). I have found an "onload" option for the body tag on dotnetspider.com, but it doesn't seem to be working for me. Please take a look and let me know of any improvements I could make. Thx Code: <body onload="loadMusic()"> <p> <script type="text/javascript"><!-- function loadMusic() { var r=confirm("Would you like a background tune?"); if (r==true) { <input type="button" onclick="show_confirm()" value="Show a confirm box" /> <object class="plugin_video" classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" codebase="http://www.apple.com/qtactivex/qtplugin.cab" height="480" width="640"> <param name="autoplay" value="false" /><embed title="QuickTime" hidden="true" src="sounds/siteBG.wav" mce_src="sounds/siteBG.wav" autoplay="true" loop="true" controller="true"></embed> </object> } else { alert("If you change your mind reload the page to choose again."); // --></script> Ok, I need some help with this. When you click the close button on your browser, I want it to have a confirmation. Saying "**Click OK to be redirected to a new page**" something like that. If you click "OK" you are redirected to another page. If you hit CANCEL, then it closes out. It doesn't have to be a confirmation. Just needs to be something that has an option. (Maybe return xx?) Anyways, here's what I've got: Code: <script type="text/javascript" language="javascript"> var sure = false; var lin = false; function sureF() { if(!sure && !lin) { sure = true; var con = confirm("**Are you sure you want to leave?**") if(con == true) { location.href = "http://www.google.com/" return con; } else { alert("Sorry") } } } window.onbeforeunload = sureF; </script> What that does, is when you click close on your browser, it will say "Are you sure you want to leave?" you click "OK", and you get redirected to google .com (How I set it) BUT then a popup comes up saying, "Are you sure you want to navigate away?" which I don't want at all. As you can see, my script is quite messed up. Could you help me out? Thanks. Hi, when my page loads it starts with a confrim box. If "Cancel" is selected then the rest of the page loads fine. If "Ok" is selected nothing after the confirm box loads. Any ideas. Also, it appears that IE and Firefox have trouble with this type of media and Chrome will only play the audio file for about 15 seconds. Any solutions?

The page says there is an error and the error is Object expected on the ClientScript... line. I have this same functionality with alert boxes and they all work. What gives? Hello, this is not and advert This is a class i built in javascript What it dose: When users leave a site that has a confirm you want to leave box from the browser Why have i posted: I have seen around on the internet posts about how to do such a thing so i though i would get hits to codding forum when user search for such a thing and any one of codding forum members could help it get better Well this is a nice little object to use insted that dose a light box effect and brings up a Yes/no true/false box you set what you want it to say The JSON Object PHP Code: confirmBox = { 'message' : 'This is a Confirm Box', 'trueTxt' : 'True', 'complete' : true, 're' : '', 'falseTxt' : 'False', 'onTrue' : 'alert("true")', 'onFalse' : 'alert("false")', 'setTrue' : function(ontrue){ this.onTrue = ontrue + "confirmBox.update('true')"; }, 'setFalse' : function(onfalse){ this.onFalse = onfalse + "confirmBox.update('false')"; }, 'setTrueText' : function(trueText){ this.trueTxt = trueText; }, 'setFalseText' : function(falseText){ this.falseTxt = falseText; }, 'setText' : function(text){ this.message = text; }, 'hide' : function(){ var bg = document.getElementById('___confirmBox_bg'); var center = document.getElementById('___confirmBox_center'); var dialog = document.getElementById('___confirmBox_dilog'); center.removeChild(dialog); bg.removeChild(center); document.body.removeChild(bg); }, 'show' : function(){ this.createBG(); this.createCenter(); this.createDialog(); }, 'update' : function(sw){ this.re = sw; }, 'state':function(){ if(this.re = ''){ return false; }else{ return this.re; } }, 'createBG' : function(){ var bg = document.createElement("div"); bg.setAttribute('style', "display: table; position: absolute; top: 0%; left: 0%; width: 100%; height: 100%; background-color: black; z-index:1001; -moz-opacity: 0.8; opacity:.80; filter: alpha(opacity=80);"); bg.setAttribute('id', '___confirmBox_bg'); document.body.appendChild(bg); }, 'createCenter' : function(){ var center = document.createElement('div'); center.setAttribute('style',"#position: absolute; #top: 50%; display: table-cell; vertical-align: middle; margin-left:auto; margin-right:auto;"); center.setAttribute('id', '___confirmBox_center'); document.getElementById('___confirmBox_bg').appendChild(center); }, 'createDialog' : function(){ var dialog = document.createElement('div'); dialog.setAttribute('style', "display:block; width: 300px; padding: 16px; background-color: white; z-index:1003; margin-left:auto; margin-right:auto;"); dialog.setAttribute('id', '___confirmBox_dilog'); dialog.innerHTML = this.message + '<div align="right"><input type="button" onclick="eval(confirmBox.onTrue); confirmBox.hide();" value="' +this.trueTxt + '" /><input type="button" onclick="eval(confirmBox.onFalse); confirmBox.hide();" value="' + this.falseTxt + '" /></div>'; document.getElementById('___confirmBox_center').appendChild(dialog); }, } Then this is how you call it and set propertys Code: <script src="confirmBox.js" type="text/javascript"></script> <script type="text/javascript"> confirmBox.setText("This is a test"); //Sets the text to show in the box confirmBox.setTrueText("I can see it"); // sets the text on the return true button confirmBox.setFalseText("I can't see it"); // sets the text on the return false button confirmBox.setTrue('alert("Thanks");'); //what to do when true is clicked confirmBox.setFalse('alert("Your a lier");');// what to do when false is clicked confirmBox.show(); // Show the confirmBox </script> Hello, I'm new to Javascript, but have been programming in PHP and other web codes for 4 years now. I was wondering how you would check if a checkbox was ticked, upon its selection and then unhide HTML content, and then hide such content when deselected.. So far I have this: Code: <script type="text/javascript"> function Agree() { document.getElementById("stepTwo").className = ""; } </script> Which is called by onclick="Agree()" on the select box itself.. I understand an if statement is needed, but how would one go about doing this as my if statements do not appear to be working. Hi I really really really need your help since I have no idea about this. How can I insert the Javascript Confirmation Alert into the del.php file? I have this del.php file PHP Code: <?php require ("include/config.php"); $id=$_REQUEST['id']; $strSQL = "DELETE FROM change WHERE id = '".$id."' "; $objQuery = odbc_exec($conn,$strSQL); if($objQuery) { echo "<script language='Javascript'>alert('Deleted.'); window.location=\""."index.php?action=syif\"</script>"; } else { echo "Error Delete [".$strSQL."]"; } odbc_close($conn); ?> This is the confirmation javascript Code: <html> <head> <script type="text/javascript"> function show_confirm() { var r=confirm("Delete?"); if (r==true) { alert("Deleted!"); } else { alert("Cancelled!"); } } </script> </head> <body> <input type="button" onclick="show_confirm()" value="Show confirm box" /> </body> </html> I've been trying to write a script that activates a confirm box when a browser window is closed. I want this to occur only when they try to close the window, not if they click on links on the page to navigate elsewhere. The confirm box then gives the option to continue closing as they intended or, if they click on ok (or cancel if it's easier), navigate to another page I specify. The script below works but it displays a confirm box when you close the window and click on links. Code: <script type="text/javascript"> function show_confirm() { var r=confirm("Wait! Would you like check out yahoo?"); if (r==true) { window.open("http://www.yahoo.com"); } else { window.close(); } } window.onbeforeunload = show_confirm; </script> I understand you may be able to create a variable that you then attach to any links on the page you don't want to activate the confirm box. I don't know how to do this. Thank you. I'm working on a bank website that needs disclaimers on their external links. I've searched for a tutorial or a script I could understand but need additional help if anyone is willing.. Here's my page with external links: http://designphilanthropy.org/services/links/ Here's the js I used from the previous bank design (I don't see any code here that will do what I need): Code: <script language="javascript"> <!-- Hide window.resizeTo(440, 440); function go() { var width = screen.width; var height = screen.height; if(width<650) { width = 600; height = 400; } else { width = width - 200; height = height - 100; } window.resizeTo(width, height); location.href=""; } // end Hide --> </script> And here's the code on the "yes" button: Code: <input type="button" VALUE="YES" onclick="javascript:go();"> The link opens the disclaimer and populates the url in the browser, but I don't know how to write the js for it to continue to the destination after clicking "yes" Any help would be greatly appreciated... Hi, im using this code as a fancybox replacement for confirm. Code: function fancyAlert(msg) { jQuery.fancybox({ 'modal' : true, 'content' : "<div style=\"margin:1px;width:240px;\">"+msg+"<div style=\"text-align:right;margin-top:10px;\"><input style=\"margin:3px;padding:0px;\" type=\"button\" onclick=\"jQuery.fancybox.close();\" value=\"Ok\"></div></div>" }); } function fancyConfirm(msg,callback) { var ret; jQuery.fancybox({ modal : true, content : "<div style=\"margin:1px;width:240px;\">"+msg+"<div style=\"text-align:right;margin-top:10px;\"><input id=\"fancyConfirm_cancel\" style=\"margin:3px;padding:0px;\" type=\"button\" value=\"Cancel\"><input id=\"fancyConfirm_ok\" style=\"margin:3px;padding:0px;\" type=\"button\" value=\"Ok\"></div></div>", onComplete : function() { jQuery("#fancyConfirm_cancel").click(function() { ret = false; jQuery.fancybox.close(); }) jQuery("#fancyConfirm_ok").click(function() { ret = true; jQuery.fancybox.close(); }) }, onClosed : function() { callback.call(this,ret); } }); } function fancyConfirm_text() { fancyConfirm("Ceci est un test", function(ret) { alert(ret) }) } how can i use fancyConfirm via an onclick in a hyperlink? thanks for your help! I am not sure why this is happening, but the script is working and throwing an alert but still submits. Code: <script type="text/javascript"> function check(a,b) { var obja = document.getElementById('email') var objb = document.getElementById('confemail') if (obja.value==objb.value) {} else {alert("The e-mail fields aren't the same!!") } return false; } </script> Code: <table> <tr><td colspan="2">Email:</td></tr> <tr><td colspan="2"> <input type="text" name="email" class="wide" id="email"></td></tr> <tr><td colspan="2">Confirm Email:</td></tr> <tr><td colspan="2"> <input type="text" name="confemail" id="confemail" class="wide"></td></tr> <tr><td colspan="2"><br /> <input name="Submit" type="submit" value="Submit Help Request" onclick="check('email','confemail') "></td></tr> </table> does anyone see the issue? Thanks for any help. http://tinyurl.com/bw2y3sr This is my site and I want to create a Yes and No dialogue box when user closes a browser so this popup confirm dialogue should appear. Can anyone help me? I have the following code written to give a user the option of participating in our survey, however, I cannot get it to only pop up when leaving the domain vs. clicking links internally. I have searched and searched and tried to implement code that I found on here among other sites without luck. I know I am just screwing up something simple so I need your help! I have also tried to implement code to set and read cookies so that it doesn't pop up excessively for a user. Although I would be ok without the cookie code. Here is what I got: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <script> window.onbeforeunload = function(){ location.assign('http://www.survey.com'); return "Thanks for visiting! We would appreciate if you could take the time to fill out our short survey to enhance your experience with our organization. To take our survey please hit CANCEL below. To continue without taking our survey just hit OK. Thanks again!"; } </script> </body> </html> Thanks in advance for your help. I didn't include any other code that I tried to implement as I figured it would be easier for you all to direct me in the right direction and help implement the code into mine. hi all, ok, i have been asked to alter our project management system (one i wrote) to alert users to the fact that they are closing windows with unsaved work in - some of them forget they have edited a page and just close the window. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script type="text/javascript"> var docChanged = false; function docChange(){ docChanged = true; } function checkForChanges() { if(docChanged == true) { return "All changes made to this page will be lost!"; } } window.onbeforeunload = checkForChanges; </script> </head> <body> <form id="form1" name="form1" method="post" action=""> <label> <input type="text" name="one" id="one" onchange="docChange()" /> </label> <label> <input type="text" name="two" id="two" onchange="docChange()" /> </label> <br /> <a href='http://www.google.com'>Google</a> </form> </body> </html> the above will prompt the user if they want to save if fields etc have been changed. is there a way i can dynimcally add the onchange="docChange()" to all fields on a page? the system has hundreds of fields and doing a mass search and replace might be very dangerous lol. im pretty sure it can be done but wouldnt know where to start. ive never really had enough time to learn all the window.addEventListener stuff. how can you do onclick="return getconfirm('do you want to logout?');" onClick="window.location('logout.asp');" on the same button , if confirm then go url else stay here ? thank you ok so all I want to do is allow a user to confirm that they've clicked the deactivate button...if they click 'ok' deactivate the affiliate...else just return to the list what is happening is I click on deactivate and the confirmation pops up (so far so good); if I click ok then it deactivates the affiliate the way it's supposed to - but if I click cancel it still deactivates the affiliate instead of returning to the list Code: <script type="text/javascript"> function confirmation() { if (confirm("Are you sure you want to deactivate this affiliate? Doing so will deactivate all of its users as well.")){ window.location = "affiliates.php?deactivate='.$_GET['deactivate'].'"; } else { window.location = "affiliates.php"; } } </script> any help is greatly appreciated! I feel stupid for asking a question about searching arrays, when there's a very similar thread that has been answered just recently on the first page; however, I'm still having trouble contemplating my own scenario. Basically, my program prompts the user for the length of the array and then asks the user to fill the array with words. Here is where I need help: I want to confirm if the user wants to search the array for those words. If so, the user will then be prompted to enter the word he wishes to search for; if found, the location of that word will be reported and the number of times the word has been searched for will be kept track of in a separate array. Here is what I have so far: Code: /* -- phase 3 ------------------------------------------------------ search for words the user asks for */ // search variables var response; var search; while (true) { // confirmation protocol response = confirm("Do you wish to search the lexicon for a word?") if (response) { search = prompt("What word would you like to search for?"); // alert("search"); } else { alert("Thank you for wasting my time."); break; } // begin search protocol for (i=0; i<words.length; i++) { if (search==words[i]) { alert("Word found at" +i+);} } // end for loop else {alert("word not found.");} // counter array/accumulator var hits = new Array(words.length); hits[i] = 0; for (i=0; i<words.length; i++) { if (words[i] == search) { hits[i] = hits[i] + 1; alert("This word has been searched for " +hits[i]+ "times."); } } // end for loop } // end while The problem with my search seems to be that the search is parsed through the for loop; if it finds the word it alerts me that it was found at i location, but then it continues through and sees that the search does not equal the other values in the array and reports it's not found as well. My counter array is completely off, and I'm really at a loss to figure it out. I can see that the problem might be that each new search resets the hits[i] to equal 0, so no matter how many times a word is searched for, it returns a count of 1. I really want this array to track the number of hits for each word searched for, but have no clue why it's not working. Thanks for any help I can get; and please, feel free to critique my coding style, I definitely need to improve. Hi, I'm wondering if it's possible to set a variable to send through with my form using the confirm alert box. Please let me know. Much appreciated.
