I have search on google using several expressions and words and after hours of digging i'm still unable to do it.

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... 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. 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 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? 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.
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 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 ? 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 want to write some javascript code that uses arrays, I have a list of arrays named array1, array2, array3 etc. I want to perform a function on each of these arrays. I wanted to have a variable for the number after array so this is what I have: <code> var array1 = new Array ("1","2","3","4","5"); var array2 = new Array ("5","6","7","8","9"); for (var i=1; i<=2;i++){ document.writeln(("array"+i)[1]); } </code> the problem is it gives me the letters in the string array instead of the array values. How do I get javascript to treat ("array"+i) as array1? Can anyone tell me of how to take or assign a javascript variable into php.
Hello, so here's my problem. I'm trying to set a page up where I can post a list of things on one side, with a static image on the other. Each of the items on the list will be a link to the item named. The idea is that when people mouse over one of the links, the static image will change to show a picture of what the named item is. I've been tinkering around with it (I'm pretty much only doing this out of self interest, and have been using stuff like w3schools for a few weeks to self teach) and what i have so far is the following. I've a feeling I'm doing something massivly stupid or have messed up one of the commands. If anyone could take 2 minutes to have a quick look over it, i would be most grateful. Thanks in advance! Code: <script type="text/javascript">
function SwapSpecificOtherImage()
{
document.getElementById("SwapMe").src='cardimage';
}
function SwapBackSpecificOtherImage()
{
document.getElementById("SwapMe").src="url of default image";
}
var cardimage
</script>
<title>Untitled Document</title>
</head>
<body>
<img id="SwapMe" class="thumbnail" src='cardimage' />
<a href="link to item" onmouseover="cardimage='link to image of item'">Item name</a>
<a href="link to 2nd item" onmouseover="cardimage='link to image of 2nd item'">Item name</a>
</body>
The class thumbnail is done in the css to auto set the size of the pic. all the pics i'll be using will be portrait shaped anyways. Hi, The following loop works: Code: <html>
<body>
<script type="text/javascript">
var i=0;
for (i=0;i<=5;i++)
{
document.write("The number is " + i);
document.write("<br />");
}
</script>
</body>
</html>
But the following doesn't: Code: <html>
<body>
<script type="text/javascript">
var i=0;
var x="i=0;i<=5;i++"
for (x)
{
document.write("The number is " + i);
document.write("<br />");
}
</script>
</body>
</html>
