JavaScript - Delete Variable
Hello, I have something like this:
Code: function asd() {
var timeout = setInterval('alert(\'asd\')', 3000);
}
function asd2() {
// with this function I want to remove the interval of 3 seconds for variable timeout.
}
I have variable timeout and with the second function asd2() I want to remove this variable. Similar TutorialsHi, I have a programing problem that have been around for ages. I have search on google using several expressions and words and after hours of digging i'm still unable to do it. I would like to get a value from a HTML page hosted remotely with an inconstant value. Then define this value and name as a javascript variable and apply or show in my page. Thanks for all the help P.S. Is there any way to make a domain lookup in javascript? I mean a user enters a domain and the script converts to an ip and shows to the user. If not thanks, probably it can only be done in the server side... Hello I have a php page in which I declared a js variable... right at the top of the page... <script type="text/javascript"> var tester = 0; </script> Later in the page I test this variable... <script type="text/javascript"> if (tester==1){ do some stuff!! } </script> But I keep getting an error variable _tester undefined Am I missing something obvious... I am new to js... but this seems really straightforward Hi! I have a javascript in the head of the document which has a variable named "ref2" ... ref2 is already working as I can see its value working in another function. I need to send this variable as the value of a hidden field in the form which is in the body of the document. This is my JavaScript Code: Code: function WriteContactFormStatement1 () {
var ContactFormValue = ref2;
document.write('<input type="hidden" name="UReferrersName" value="' + ContactFormValue + '" />');
}
var WriteContactFormStatement = WriteContactFormStatement1 ();
And at the end of my form, before the submit button, I have the following code: Code: <!-- START -- Javascript to print the statement for UReferrersName --> <script language="JavaScript" type="text/JavaScript"> //WriteContactFormStatement(); document.write (WriteContactFormStatement); </script> <!-- End -- Javascript to print the statement for UReferrersName --> When I execute the form, it doesn't work the way it should, plus, gives me a word "undefined" next to the "Submit" button ..... Please help !... - Xeirus. I don't know how I should do ? Quote: <html> <head> <script type="text/javascript"> function add(a,b){ y=a+b return y } var aaa = add(one,two) //one needs to get somehow get the value of yil, in this case 10 var one = function reas(){i=10;if(i<10){yil = 15}; else{yil = 10; yil = one;}; var two = 20; document.write(y) </script> </head> </html> also why doesn't this work? Quote: <html> <head> <script type="text/javascript"> function adder(a,b){ var k=a+b; return k } var hes=adder(5,kol); kol=40; alert(hes); </script> </head> </html> you cannot have variables in callback functions? Hi, here's the code Code: <div class="artworkdelete"> <a href="javascript:void(0);" id="del_<?=$artworkDetails['artwork_id'] ?>_<?=$temp_cat_id; ?>" onclick="deleteThisArtWork(this.id)">Delete</a> </div> that's actually a "Delete" link , when I click it, there's a some sort of loading animation like stuff , similar to the thing that appears when one clicks the edit button of a thread here in this forum..then and it deletes the data and doesn't need to refresh the page, i guess it is ajax.....it's not my code.. now I was asked to alter it and use a pop up box to ask the clicker "Yes" or "No" before deleting the data , what or how to change that code snippet i pasted above ? Delete this post. Thank you
The js line... delete new Obj(); brings my script to a halt in IE7. the error in the MS-VWD debugger is... "Cannot delete 'new rect()". The same line seems to work fine in FF. If I change the code to... var o = new Obj(); delete o; - all works fine in IE. Can someone explain why this occurs? btw... the actual code is something like... delete new rect().getElem(elem).hcenterInRect(parRect).setElem(elem); so there's a bunch of processing between the new and deleting of the object ("rect"). this is obviously not a big problem but i was just curious as to how IE was interpretting this line. thanks to any of you javascript wizards that may have a clue. I am trying to delete or hide better to say advertisment on Forumotion forum. http://testforum-lolz.serbianforum.info/ When you use firebug to inspect you can find this: Code: html body .w74704f, html body .w74704f iframe, html body iframe[name="google_ads_frame"], html body .w74704f iframe[name="google_ads_frame"], html body #wrap #page-body div.w74704f, html body #page-body .w74704f {

When i type display:none; in every single code so I can hide it it doesent work. I dont know can there be any javascript for it. Maybe this can help: Hi all! I created a form where users are allowed to delete a specific row of data by clicking the "cancel" button from the drop down menu. However, I have a problem deleting my data using the javascript. Apparently, I only able to delete the first row of the data but not for the rest! The following is the code i have: PHP Code: <html> <body style="background-color:#E0FFFF;"> <script language="javascript" > <!-- hide function submitRequest(val) { document.forms[0].submit(); } // end hide --> </script> <?php $con = mysql_connect("localhost","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("my_course", $con); $result = mysql_query("SELECT * FROM Courses ORDER BY Year, Sem, CourseCode"); $result1 = mysql_query("SELECT * FROM Courses ORDER BY Year, Sem, CourseCode"); echo "<table border='1' cellpadding='2' cellspacing='0'> <tr> <th>CourseCode</th> <th>CourseName</th> <th>Year</th> <th>Sem</th> <th>Grade</th> <th>Option</th> </tr>"; ?> <?php while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['CourseCode'] . "</td>"; echo "<td>" . $row['CourseName'] . "</td>"; echo "<td>" . $row['Year'] . "</td>"; echo "<td>" . $row['Sem'] . "</td>"; echo "<td>" . $row['Grade'] . "</td>"; echo "<td>"; ?> <?php ?> <form name="form1" action="submitDelete.php" method="post"> <select name="cancel" onchange="submitRequest(this.value);"> <option value=> </option> <option value="<?php echo $row['CourseName'];?>">Cancel</option> </select> </form> <?php echo "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); ?> <br/> <br/> </body> </html> Thanks in advance! Hello everybody I have a problem with Java Script damned I want to add the values of several variables in one variable and then use this variable, which contains the values of variables You can see the following example HTML Code PHP Code: <input type="text" name="txt1" /> <br/>age <input type="text" name="txt2" /> <br/><br/> <input type="button" name="submits" value="send"/> Javascript Code PHP Code: field = document.getElementsByName('txt1')[0]; field2 = document.getElementsByName('txt2')[0]; submit = document.getElementsByName('submits')[0]; data = 'data=' + field.value + '&data2=' + field2.value + '&submits=' + submit.value; document.getElementsByName('submits')[0].onclick = function(){ alert(data); } After executing this code I find that the variables are not displayed values As in the following picture I want to know what the cause of this problem ? Hello I have a piece of javascrip that refreshes the page: ---------- Code: <script type="text/javascript">
<!-- Begin
function reFresh() {
location.reload(true)
}
/* Set the number below to the amount of delay, in milliseconds,
you want between page reloads: 1 minute = 60000 milliseconds.
2 minutes = 120000 milliseconds 5 minutes = 300000 milliseconds*/
window.setInterval("reFresh()",20000);
// End -->
</script>
-------- I am new to javascript and wanted to use an html options menu in order to be able to choose the refresh interval: Code: <SELECT NAME="refreshtime"> <OPTION VALUE="60000">1 min</option> <OPTION VALUE="120000">2 min</option> <OPTION VALUE="180000">3 min</option> <OPTION VALUE="240000">4 min</option> </SELECT> I know that I have to pass a variable to the function. I have tried several variations but none have worked. I have mostly received a "done with errors" warning. Any help would be appreciated. Thanks Zam This might be a stupid question, but is there any memory usage difference between var variable1, variable2; and var variable1; var variable2;? I'm learning how to use faster code hence the question.
If I manually write out "2/22/2012 4:00 PM" in TargetDate, I get the correct result for what I want to do (a countdown). But I want the countdown to always be the current day at 4pm. So I tried the code below thats commented, but it is not working. New to javascript, still reading the books, just hoping for some guidance on this. Code: Next Update: <script language="JavaScript"> var currentTime = new Date() var month = currentTime.getMonth() + 1 var day = currentTime.getDate() var year = currentTime.getFullYear() TargetDate = "2/22/2012 4:00 PM"; //TargetDate = "document.write(month + "/" + day + "/" + year) + 4:00PM"; BackColor = "white"; ForeColor = "red"; CountActive = true; CountStepper = -1; LeadingZero = true; DisplayFormat = "%%H%% H, %%M%% M, %%S%% S"; FinishMessage = "Forecasts posted"; </script> <script language="JavaScript" src="countdown.js"></script> 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>

Greetings: On the click of a button, how would I delete a certain record in a database table, w/o refreshing the page? I am new to JS and don't even know where to start. Thanks in advance. hi I do not know why the cookies can't be deleted Code: function deleteCookies()
{
var splitC=document.cookie.split(";");
var i;
for(i=0;i<splitC.length;i++)
{
var getName=splitC[i].split("=");
var cookieDelete = getName[0].replace(/^\s+|\s+$/g, '');
document.cookie=cookieDelete+"=0;expires=Thu, 01-Jan-70 00:00:01 GMT";
}
}
I found a very intressting JS function at this webpage: http://www.dynamicdrive.com/dynamici...edcollapse.htm I wonder if someone knows wihich part from the JS-file i should change/delete so i only get the fade at exempel 1 and not the slide/rolling effect. I only want the fade. The JS is: Code: //** Animated Collapsible DIV v2.0- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.
//** May 24th, 08'- Script rewritten and updated to 2.0.
//** June 4th, 08'- Version 2.01: Bug fix to work with jquery 1.2.6 (which changed the way attr() behaves).
//** March 5th, 09'- Version 2.2, which adds the following:
//1) ontoggle($, divobj, state) event that fires each time a DIV is expanded/collapsed, including when the page 1st loads
//2) Ability to expand a DIV via a URL parameter string, ie: index.htm?expanddiv=jason or index.htm?expanddiv=jason,kelly
//** March 9th, 09'- Version 2.2.1: Optimized ontoggle event handler slightly.
//** July 3rd, 09'- Version 2.4, which adds the following:
//1) You can now insert rel="expand[divid] | collapse[divid] | toggle[divid]" inside arbitrary links to act as DIV togglers
//2) For image toggler links, you can insert the attributes "data-openimage" and "data-closedimage" to update its image based on the DIV state

Now I have an html button on the basket page where I want to be able to delete the product (Cookie). I am using Code: <script type="text/javascript"> function delete_cookie ( cookie_name ) { expires = Now(); document.cookie = cookie_Name+"= ;expires="+expires.toGMTString(); } </script>But I get an error that says the cookie is not delcared? But it does exist because I retrive the name of the cookie when looping through the cookie list. What am I doing wrong here? This function is part of a page that will delete a product that a customer has selected. The question I have is what is the line line that actually removes the item from the list of products chosen? From my understanding, in order to establish an array, new array = elements[i] has to be added but Im thinking that elements[i] is the array that holds the product. Does the "0" in this line actually delete the item? document.template.elements[i].value = 0 ; Code: function del_item(X,msg) {
// var msg = "Are you sure you want to delete this line item?"
resp = confirm("Are you sure you want to " + msg + "?") ;
if (resp) {
var len = document.template.elements.length
//loop to put into arrays
for (var i = 0; i < len; i++) {
var lname = document.template.elements[i].name ;
if(lname == X) {
document.template.elements[i].value = 0 ;
process_order(0) ;
document.template.loginpath.value = "CO" ;
document.template.submit() ;
}
}
} else {
return ;
}
}
