JavaScript - Display The Result Of A Variable Without Using Alerts
Similar TutorialsGood day to you all, I'm working on a form which would display the result in the same div that the form is. Here is my code so far: PHP Code: <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> <textarea name="html"></textarea><br /> <input type="submit" onclick="load('<?php echo $_SERVER['PHP_SELF']; ?>','page');"/><br /> </form> Preview:<br /> <?php if(isset($_POST['html'])) echo stripslashes($_POST['html']); ?> <script type="text/javascript"> function ahah(url, target) { document.getElementById(target).innerHTML = ' Fetching data...'; if (window.XMLHttpRequest) { req = new XMLHttpRequest(); } else if (window.ActiveXObject) { req = new ActiveXObject("Microsoft.XMLHTTP"); } if (req != undefined) { req.onreadystatechange = function() {ahahDone(url, target);}; req.open("GET", url, true); req.send(""); } } function ahahDone(url, target) { if (req.readyState == 4) { // only if req is "loaded" if (req.status == 200) { // only if "OK" document.getElementById(target).innerHTML = req.responseText; } else { document.getElementById(target).innerHTML=" Error:\n"+ req.status + "\n" +req.statusText; } } } function load(name, div) { ahah(name,div); return false; } </script> My problem is when I click on the button , the text in my text area don't show. Can somebody help me. Thanks! Hello ! I am trying to create an auto suggest drop down. I have some ASP and Javascript code that I am using as an Autosuggest. Trouble is, the result displays on the main page, not under the text box like a drop down menu. I need help in getting the results to display correctly underneath the textbox.

any comments or suggestions would be greatly appreciated. Hello! I am working on creating a basic calorie calculator with Javascript and my code is not showing the results after the user makes their selections. I've created a simple function to obtain the user's weight, activity and duration info but when I use the GetElementById to retrieve the result, it does not show up. Any help would be much appreciated to make this work. Thanks. Code: <head>

Hi, i will try to be as brief as possible. I have a page A with form: Code: <form id="search" action="find.html" method="get"> ... (some select options) ... <input type="submit" class="submit" value="search"> this form look up some holiday destination which appears on this page with url: (example) Code: www.domain.com/find.html?destination=italy&price=500 Now, I dont want to display result on this page, but on page B, in iframe. I found a way how to redirect output as a link to properly show in iframe on page B. Page A contains: Code: <a href="pageb.html?http://www.domain.com/find.html?destination=italy&price=500">show on page B</a><br> Page B contains: Code: <script type="text/javascript">
<!--
function loadIframe(){
if (location.search.length > 0){
url = unescape(location.search.substring(1))
window.frames["iframe"].location=url
}
}
onload=loadIframe
//-->
</script>
<iframe src="" name="iframe" id="iframe"</iframe>
In this case page B will properly load requested link in iframe. Problem is it is just a static link... I want to display search result from the form. Thanks a lot for your help... 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. I'm trying to get this assignment done for class. I've spent 3 hours on this part alone. These aren't supposed to be that hard. However, it keeps saying that the variable toppings is undefined. Why is it doing that? Especially since it can find the values when I tell it to print them out with an alert. Yet it won't execute the final part where I go to the confirm. Code: <html>
<head>
<script>
function confirm(theForm)
{
var selectedItems = "";
var i = 0;
for(i =0; i < theForm.toppings.length; i++)
{
alert(theForm.toppings[i].value);
if (theForm.toppings[i].checked==true)
{
selectedItems = selectedItems + "\n" + theForm.toppings[i].value;
}
}
var r = confirm("You have selected " + selectedItems + "\n" + "Is this correct?");
if (r == true)
alert("Ok");
}
</script>
</head>
<body>
<form name="form">
<label for="toppings">
<BR><Select name="toppings" MULTIPLE id="toppings">
<OPTION SELECTED> Cheese
<OPTION> Pepperoni
<OPTION > Onions
<OPTION> Sausage
<OPTION> Olives
</SELECT>
<input type="button" value="Confirm selection." onClick="confirm(this.form)">
</form>
</body>
</html>
Never mind, it was because I had named the function "confirm()". A really dumb move on my part. http://becompleteamerica.com/index.p...tact&Itemid=80 It works awesome in all browsers but IE 7 & 8. The custom "alert" is actually a dialog box, with a background fader underneath it, kind of like lightbox. Any ideas why IE doesn't play nice? Thx I'm just starting out with javascripting and am trying to make a Choose your own Adventure game. My goal is to have the scenes and alerts change depending on the button clicked, but I'm stuck, unfortunately. I keep getting the same alerts repeated and my image doesn't change. I think I'm missing code or have made a mistake somewhere, but have no idea what I've done wrong or left out. I don't know if this type of programming has a more specific name, too, so I wasn't sure what to search for to get help. Hopefully someone can guide me in the right direction. I've included my beginning code below. Thanks Code: <script type="text/javascript">
var curScene = "0";
function userChoice(decision){
alert(decision);
/*welcomepage*/
if(curScene == 0) {
alert("Welcome to the game. Chose 1 or 2.");
}if(decision == 1) {
alert();
curScene = 1;
}else if(decision == 2){
alert();
curScene = 1;
}
/*Scene1*/
if(curScene == 1){
alert("go left or right");
}if(decision == 1) {
alert("you went left and fell in a hole");
curScene = 3;
}else if(decision == 2){
alert("you go right and come upon a zebra");
curScene = 4;
}
}
document.getElementById("sceneimg").src=
"scene" + curScene + ".jpg";
</script>
<img id="sceneimg" src="scene0.jpg" alt=
"Stick Figure Adventure" />
<input type="button" value="1" onClick=
"userChoice(1)">
<input type="button" value="2" onClick=
"userChoice(2)">

I'm trying to make a basic rss reader with a google reader-esque functionality of clicking on article names and being able to expand/collapse that article. I'm working on the expand part and am going crazy. I am having no trouble getting content and displaying it without the onclick function but when I try to integrate onclick I can just get the titles. here's the snippet. any help? Code: <!-- HTML -->
<body>
<div id="feeddiv"></div>
<script type="text/javascript">
// feed stuff using Google Feed API
function feedLoaded(result)
{
if (!result.error)
{
// Grab the container we will put the results into
var container = document.getElementById('feeddiv');
container.innerHTML = '';
// Loop through the feeds, putting the titles onto the page.
for (var i = 0; i < result.feed.entries.length; i++)
{
var entry = result.feed.entries[i];
var content = entry.content;
var title = entry.title;
var url = entry.link;
var div = document.createElement('div'); //parentDiv for articles
var articleTitle = document.createElement('div');
articleTitle.setAttribute('name', i); //set articleTitle name to article's place in array
articleTitle.setAttribute('style', 'font-weight:bold;font-size:15px;');
articleTitle.innerText = title;
articleTitle.onclick = function() {populate(content, title, url, i);};
div.appendChild(articleTitle); //adds title to div
container.appendChild(div); //adds div to the container
}
}
}
function populate(content,title, url, i)
{
var article = document.getElementByName(i); //gets articleTitle
//clickable title
var a = document.createElement('a'); //creating title link
var href = document.createElement('href');
a.setAttribute('href', url); //putting actual url into html
a.setAttribute('style', 'font-size:25px;');
a.innerText = title;//still puts into html
//Text
var snippet = document.createElement('p'); //creates <p> to throw articles in
snippet.innerHTML = content; //renders the article
article.appendChild(a);
article.appendChild(snippet);
}
</script>

I am fairly new to coding HTML with Javascript. I am hitting my head onto the table because i cannot figure out how to pull the variable value out in a document.write statement. Basically, I am calling a function to give me a random number between 1-4. I use that randomNumber to attach to different .jpg, descriptions, and URL's. So far, i have only got the image to display, but unable to get the link and description to display. Basically, i am trying to diplsay random ads and links like the one at the top of this page. p.s. I know I am getting the randomNumber out of my function becasue I can call a simple document.write(randomNumber) and it works. Substitute adDesc and adURL in place of randomNumber and I also get the description and link respectively. Code: <div id="main">
<div id="ads">
<script type="text/javascript">
// generate a random integer from 1 to 4
var randomNumber = randInt(4);
// description of the random ad
var adDesc = adDescription(randomNumber);
// URL of the random ad
var adURL = adLink(randomNumber);
document.write("<a href=adURL >");
document.write('<img src="ad' + randomNumber + '.jpg" title=adDesc >');
document.write("</a>");
</script>
</div>
If you haven't guessed it, I am pretty new. Reading a book and trying to put code into action are completely different. Thanks for any help! Basically I am being restricted by a third party program that manages my email list. When a person signs up for my website it first adds them to my external email list and then to my MySQL database. In order to do this you have to pass the information of the form to the next page where you can "display" it. Nothing except this display function seems to work. So what I am trying to do is take what is outputted by this display button and store it in a javascript variable. Then transfer this variable to a form which will auto submit and start the PHP registration. I need help pulling the output of the script, right now I can either get an undefined or the entire HTML code. Is there another option? Here is my code: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

Hi, I am a newbie in JS, and have already been stuck with this problem for the whole day. Basically I want to display a var returned from a function with <fmt:message/> tag. It sounds easy, but somehow I just can't get it to be display correctly (Tried with alert() and it worked). Here is my code: ------------------------------------------------------------------------------------------- <script> function ReturnTime() { var dateobj=new Date(); if (dateobj.getSeconds()%30==0) { return dateobj.getSeconds(); } else { return dateobj.getSeconds(); } } time1 = ShowTime(); alert(time1); </script> <fmt:message key='content.currentTime'/>: <cut value="${time1}"/> ------------------------------------------------------------------------------------------------------------------------- I might have done some stupid things here. But I am very new to JS (2 days of experience so far). So please be patient. Your kind help will be very much appreciated. Regards, Robert 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. 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 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! 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 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.
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> |
