JavaScript - Form Variable To A Javascript Variable
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 Similar TutorialsHi! 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. so i have this code i am working on(this is a dumbed down version of it) Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
$("#Submit").click(function(){
for (i=0;i<=50;i++)
{
$.ajax({
url:"process.php",
type:"get",
data:$("form").serialize(),
success:function(response){
var obj = jQuery.parseJSON( response );
var success = obj.success;
var actionsNumber = obj.number;
$("#result").html('There have been '+actionsNumber+' loops completed');
}
})
}
})
})
</script>
</head>
<body>
<form action="" method="post">
<p>
<label><strong>Number of Loops</label>
</p>
<input name="count" type="text" value = "1"/>
</p>
<p>
<input id="Submit" type = "button" value = "Send">
</p>
</form>
<p id="result">There have been 0 loops completed</p>
</body></html>
so you see this for loop for (i=0;i<=50;i++) I want it to be able to be like for (i=0;i<=count;i++) so that it will loop the number of times inputted also(though i dont know if this is something that i need to use js for) On my full code there are other textboxes that need to be sent to process.php each time that it is run. How can i achieve this? also before anyone asks i have googled this and searched around yet i havent been able to figure this out, everything i have tried hasnt worked and here is the process.php PHP Code: <?php session_start(); // process the form data here //::::::::: // if(!isset($_SESSION['number'])){ $_SESSION['number'] = 0; } $number = $_SESSION['number']++; // output json response echo'{"success":"true","number":"'.$number.'"}'; ?> I have used php with forms but can I do easy form to java vars? I saw one snippit of code that did it when I was newer but did not understand it. what is the way you usually do this? I've been having a hard time with this and was hoping someone here would take a little pity and render me a great service. I'm using a javascript to get the user's timezone and am trying to pass the response to an input field in a php form. With a great deal of trial and error I got a demo working to a point but I'm stuck. Here's what works now: Code: <p id="timezoneInformation" style="text-align: center;">click here</p>
<script src="jstz.js"></script>
<script>
var container = document.getElementById("timezoneInformation");
var showTimezone = function () {container.textContent = jstz.determine().name();};
container.addEventListener("click", showTimezone);
</script>
jstz.js is from Automatic timezone detection using JavaScript The example above is as far as I've gotten. I would like to send the results to a form field to submit to the server. It's probably a lot easier than I'm making it out, but I've had little success and would welcome any help. Thank you. hi , i am trying to pass a javascript variable into URL ..but not getting the value.. var newID = 2; row.insertCell(6).innerHTML = "<a href=Update_Gate.cfm?GateIdVar=newID>Edit Gate</a>"; i am getting "newID" in Update_Gate.cfm page ... i want to pass this javascript variable in url and read it on the other page as form field value any help !! Hi all, I am new to JS and usually learn by studying code posted online and modify it to have it do what I need. Recently, I used a totaling plugin for an online ordering form which does the below: item1 qty(user input text) * preset price = total price item2 qty(user input text) * preset price = total price item3 qty(user input text) * preset price = total price -------------------------------------------------------- grand total -------------------------------------------------------- The JS code which passes the grandTotal variable is as below: Code: function ($this){
// sum the total of the $("[id^=total_item]") selector
var sum = $this.sum();
$("#grandTotal").text(
// round the results to 2 digits
"₹" + sum.toFixed(2)
);
}
The problem I have is the above grandTotal displays the final value when put into a table like below: Code: <td align="right" id="grandTotal"></td> But I am unable to make it work by passing it into a variable within the form fields. I would like to do something like this: Code: <input type="text" name="grandTotal" id="grandTotal" readonly="readonly" /> Can somebody please help me fix this? Any help will be greatly appreciated. Thank you. Can anyone tell me of how to take or assign a javascript variable into php.
Hi, 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.

Can anyone tell me what I am doing wrong? I am not very used to Javascript and perhaps I am going about it totally the wrong way. Help! Gordon Is it possible to pass the value of a javascript variable through src? For example, instead of... <script type="text/javascript" src="/myfolder/myjsfile.js"></script> ...could I have something like... <script type="text/javascript" src=JS VARIABLE VALUE></script> What would be the syntax for this? Is it even possible? Thank you! I get the screen resolution with this script: <SCRIPT language="JavaScript"> <!-- height = screen.height; width = screen.width; document.write(width + "x" + height); var x = ( width + "x" + height); //--> </SCRIPT> Now I have some links below and I want to use bold if the link has the same screen resolution: <a href="page1">800x600</a> <a href="page2">1024x768</a> <a href="page3">1680x1050</a> <a href="page4">1920x1200</a> Supposing my screen resolution is 1920x1200, the result should be: 800x600 1024x768 1680x1050 1920x1200 How do I do that? Thx!! 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> 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 ? 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.
Gonna be asking a few Q's about a quiz javascript i'm making. I'm pretty new to JS. I have this, a select box, in the body. Code: <div align="center"><center><p><strong>Your response:</strong> <select
name="theresponse" size="1" onChange="responses()">
<option value="-----">----</option>
<option value="a">a</option>
<option value="b">b</option>
<option value="c">c</option>
<option value="d">d</option>
</select>
Then the relevant bit of script lower down Code: var loop=0
function responses(){
loop++
var temp2=document.instantquiz.theresponse
var temp3=temp2.options[temp2.selectedIndex].text
if (temp3!=solution[whichone]&&temp2.selectedIndex!=0)
document.instantquiz.thesolution.value="Sorry, the correct answer is "+solution[whichone];
else if(temp2.selectedIndex!=0)
document.instantquiz.thesolution.value=compliments[whichone];
}
I want to add 1 to 'loop' (so that people can't score twice etc.). The problem I have here is that loop just doesn't want to go up.

var optionsa = {
script:"test.php?",
varname:"one",
json:false
};
var as_jsona = new bsn.AutoSuggest('oneone', optionsa);
</script>
