JavaScript - Deleting Cookies
i create cookies that contain multiple values using Jquery cookie plugin e.g, $.cookie('biz', ['foo', 'bar', 'lact'], {path: '/', expi 7}); from this url http://localhost/categories/educatio...r/universities and use a.remove('foo'); to remove the value after splitting, before removing value i count the number of value and if one remains to delete the cookie 'biz' entirely, even though i could remove the values, one always remains which cannot be remove from this url but only from http://localhost/categories
i use .htaccess to rewrite the url, function of remove is : Array.prototype.remove=function(s){ var i = this.indexOf(s); if(i != -1) this.splice(i, 1); } please help Similar TutorialsEDIT: Post deleted
I made a new thread for a problem that I solved a little after posting so I have removed the question in order to not waste anyone's time
How can I to delete white spaces around parameter that I to pass with HTML forms. For example, if I have 'firstname lastname ' or ' firstname lastname', exist it a builtin function in javascript to obtian 'firstname lastname'? savio My table starts like this: Code: <table> <tr> <td rowspan='2'></td><td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> </table> When an addRows button is clicked, the first two rows are copied (cloned), a checbox is then inserted into the row1 cell1, then the two rows are appended: <table> <tr> <td rowspan='2'></td><td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td rowspan='2'><input type='checkbox' name='check[]'></td><td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> </table> Rows,except the first two can then be deleted by selecting the appropriate checkbox and clicking a deleteRow button. The check[] only exists after the first two rows have been copied and appended, so undefined means only two rows exist. Having a problem with the while loop. If a browser sees the next sibling of a tr as a td, the the loop should force the browser to go to the next sibling until its a tr, i.e row4. But its causing my browser(FF) to become unresponsive. Code: function deleteRow() { if(check == 'undefined') { return; } else { var check = document.getElementsByName('check[]'),row,nextRow,x; var len = check.length; for(x=len-1; x>=0; x--) { if(check[x].checked) { row = check[x].parentNode.parentNode; while(row.nextSibling.nodeName != 'tr') { nextRow = row.nextSibling; } nextRow = row.nextSibling; alert('ok'); } } } } Appreciate ans help with this? I writed the following HTML code: Quote: <html> <head> <title>Pagina di Prova</title> <script type="text/javascript" src="/home/savio/Scrivania/prova.js"></script> </head> <body> <h1 align="center">PROVA DI RIMOZIONE DI RIGHE E CELLE DALLA TABELLA</h1> <br/><br/> <table id="nometabella" border="2" align="center" cellpadding="10%"> <tr id="nomeriga1"><td>Cella 1</td><td>Cella 2</td></tr> <tr id="nomeriga2"><td>Cella 3</td><td>Cella 4</td></tr> <tr id="nomeriga3"><td>Cella 5</td><td>Cella 6</td></tr> </table> <input type="submit" value="Enter" onclick="return del()"/> </body> </html> and the following javascript code: Quote: function del() { if (document.getElementById) { var tabella = document.getElementById("nometabella"); var riga1 = document.getElementById("nomeriga1"); tabella.removeChild(riga1); } } I want to delete first row of table, but it happens nothing. How can solve this problem? I have created a calculator for my site but I am having troubles figuring out a way to make the "add row" and "delete row" functionality work correctly. I would like the user to only see 1 row of information and then add/delete rows as needed. I currently only have 4 static rows. If anyone can help it would be greatly appreciated. Thanks The page is at https://learningportal.juniper.net/j...lator/Calc.htm My table had the following layout. Code: <table> <tr> <td rowspan='2'><td> <td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> </table> After clicking an add rows button, the two rows are cloned and appended as follows with a checkbox added as shown. Code: <table> <td rowspan='2'><td> <td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td rowspan='2'><input type='checkbox' name='check'><td> <td>Data</td><td>Data</td><td>Data</td> </tr> <tr> <td>Data</td><td>Data</td><td>Data</td> </tr> </table> I want to be able to delete rows 3&4 by selecting the checkbox in row 3 and clicking a delete rows button. Regardless of how many sets of rows have been previously added, any set of rows can be deleted by selecting the appropriate checkbox(es) and clicking delete button. I'm trying to figure out how this can be done. My thinking is if checkbox is checked, calculate row index. I would then have to call deleteRow twice on that row index. Is there a better way of doing this? Say I have a <textarea> input and I want to strip all the blank lines (lines with only whitespace). I have this regular expression, why doesn't it do anything? I've tried different variations with the flags (m and g). Code: ... var output = input.replace(/^\s*$/gm, "notworking!"); ... The very same regex works fine in my text editor (Notepad2), and I can match all empty lines. Code: LINE1 LINE4 ^(line 3 has some spaces) should become Code: LINE1 LINE4 And when I finally do get this to work, how would I remove the empty line? Our site allows the user to specify his or her location, which is then stored in a cookie. As the user navigates from page to page on the site, this location is remembered. The user also has the option of changing their location. This calls a javascript function which sets the value of that location cookie to "". When another function sees that the value is "" of that cookie, it brings back the location selector. Then the user can start over and choose a location. Here's the problem: Let's say I'm on page 1 of the site and I choose location A. Then I navigate to page 2. On page 2, I say I want to change my location. Now the page shows me the location selector instead of saying that I am in location A. So far, so good. However, if I now navigate back to page 1, it thinks I am still in location A. the cookie was deleted for page 2, but still remembered for page 1. It isn't a cache issue; if I reload the page, page 1 will still say that I am located in location A, even though on page 2, I elected to delete that cookie (or to set its value to ""). What is a better way to delete cookie so that if I were to navigate back to a page on which I'd previously set the cookie, it will now know that the value is the new value (""), and not the value I'd originally set the first time I visited the page? THANK YOU! I wrote a script that should delete all table rows at once. For loop deletes all rows except row 1 and row 3. Further clicking on the delete button, deletes row 1 and then 3. While loop ,on the first click on the delete button, also leaves rows 1 and 3 not deleted. Further clicking on the delete button, does not delete these rows. I was sure that both version of the script should delete all rows in the table at once. Could someone look at the script and tell me what is wrong? Thank you very much Code: <html> <head> <title>Deleting All Table Entries</title> </head> <script type="text/javascript"> /* WHILE LOOP var i=0; function deleteAll() { document.getElementById("deleteButton").onclick=function() { var table=document.getElementById("myTable"); while(i<table.rows.length) { table.deleteRow(i); i++; } } } */ /*FOR LOOP*/ function deleteAll() { document.getElementById("deleteButton").onclick=function() { var table=document.getElementById("myTable"); for(var i=0; i<table.rows.length; i++) { table.deleteRow(i); } } } window.onload=deleteAll; </script> <body> <table id="myTable"> <tr> <td>Row 0</td> </tr> <tr> <td>Row 1</td> </tr> <tr> <td>Row 2</td> </tr> <tr> <td>Row 3</td> </tr> <tr> <td>Row 4</td> </tr> </table> <button id="deleteButton"> Delete All Rows in the Table </button> </body> </html> Ive looked it up on google and yahoo but i just cant find good explanations on how to use cookies?
Hi is it possible to email cookies to my email address. I have a order form and it saves all the information within a cookie and then goes to the payment page. I want to email the order details along with the payment detail to myself. Is this possible and how. Below example of my cookie: Code: function nextForm() { document.cookie = "prod1=" + encodeURIComponent(document.forms[0].prod1.value); document.cookie = "prod2=" + encodeURIComponent(document.forms[0].prod2.value); document.cookie = "prod3=" + encodeURIComponent(document.forms[0].prod3.value); location.href="Payment.html"; } I then have my payment cookie: Code: function paymentForm() { document.cookie = "FirstName=" + encodeURIComponent(document.forms[2].firstname.value) + ";secure=true"; document.cookie = "LastName=" + encodeURIComponent(document.forms[2].lastname.value) + ";secure=true"; document.cookie = "Email=" + encodeURIComponent(document.forms[2].email.value) + ";secure=true"; document.cookie = "PhoneNumber=" + encodeURIComponent(document.forms[2].telephone.value) + ";secure=true"; document.cookie = "Address=" + encodeURIComponent(document.forms[2].address1.value) + ";secure=true"; document.cookie = "Address=" + encodeURIComponent(document.forms[2].address2.value) + ";secure=true"; document.cookie = "City=" + encodeURIComponent(document.forms[2].city.value) + ";secure=true"; document.cookie = "Province=" + encodeURIComponent(document.forms[2].province.value) + ";secure=true"; document.cookie = "PostalCode=" + encodeURIComponent(document.forms[2].code.value) + ";secure=true"; document.cookie = "AmountDue=" + encodeURIComponent(document.forms[2].totalDue.value) + ";secure=true"; document.cookie = "CardName=" + encodeURIComponent(document.forms[2].cardName.value) + ";secure=true"; document.cookie = "CardNumber=" + encodeURIComponent(document.forms[2].cardNumber.value) + ";secure=true"; if (document.forms[2].correct.checked == true) document.cookie = "T&C Agreed = " + encodeURIComponent(true) + ";secure=true"; top.location.href="thankyou.html"; } and then my thankyou page from where it should be submitted to my email i am using a onload in the body but dont know what the code should look like.: Code: <body class="sale" onload="postCookie(); redirect(); return true"> <tr valign="middle"><td colspan="4" rowspan="10" align="center"><br /><hr /> <strong>Thank you for order!

Hello, I know there are dozens of threads on this topic but I can't figure out how to do what I want to do. I have three variables I want to store in a cookie when a user leaves this page which is a college project: http://jimbolgs.agilityhoster.com/wo.../ClockUTC.html They are (from the linked JS file): extraMins, geoLoc, UTCHours. I would also like to retrieve them on return to the page. Any help appreciated, Thanks. Hi, Im a bit stuck on something, any help is greatly appreciated. I want a user to input a name, age, gender, city into a form, this gets stored in some cookies and when they click submit they are taken to another page where their details are displayed in the webpage. Thanks for the help. If I create a cookie in PHP here. PHP Code: setcookie('cookie_cl_'.$client_id, 'cookie_cl_'.$client_id, $time, "/","", 0); the php script is set on domain B the javascript I want to read the cookie is set on domain B as well However, the hosted on DOMAIN A Code: <script src=domain B .js> I want the cookie to remain on domain B, but if I open the JS file using domain A, both php and JS are using domain B, though I can't seem to get the JS to find the cookie, is it looking at domain A ? am I suppose to set a domain on cookie for this to work? Hopefully this makes sense. Hi all, I need some help. I have a javascript thing on my site that changes the css layout from standard to alternate, and that works fine. Now I am wondering if it's possible for it to store a cookie, that when any of the pages on my site (this javascript thing is on every page) are re-loaded or the user navigates to a different page, it will keep the alternate stylesheet. Then, when it is changed back, the cookie gets deleted. Here's my code: Header: Code: <link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" media="screen" title="default" /> <link rel="alternate stylesheet" href="/wp-content/themes/new/darkside.css" type="text/css" media="screen" title="darkside" /> <script language="javascript" src="/wp-content/themes/new/darkside.js"></script> Darkside.js Code: // *** TO BE CUSTOMISED *** var style_cookie_name = "style" ; var style_cookie_duration = 30 ; // *** END OF CUSTOMISABLE SECTION *** function switch_style ( css_title ) { // You may use this script on your site free of charge provided // you do not remote this notice or the URL below.

Hi there, I am writing an extension for google chrome (or at least trying to, it's my first project), and I'm kinda stuck on one part. I'd like to save 2 variables, called "c" and "notes". I'd like it to get the cookies onLoad, and save them onUnload. I've tried different codes, but right now I just can't figure out how to set notes and c to the value of the cookie. Could anyone please help me? Thanks in advance. Hi there Guys, I'm looking to set a cookie that lasts 24 hours and has a specific name.
