JavaScript - Js Start Function Doesn't Work After Reset
I have a number picker that works fine BUT when I reset the fields to enter another number, the start button will not work.
I had to make it so the page reloads in order for the start button to work. This not only makes the site look worse than it already does but it's annoying to wait for the page to reload. I'd like to get all these bugs worked out and work on the site appearance after. Am I stuck with this reload thing or does someone know how I can fix it? Here's a link....http://www.psychiclotto.org/ Similar TutorialsHi! What am doing wrong? The script works -- identifies blank fields -- but the second function (change_subject) is ignored. This is the script: Code: <HEAD>
<script>
function is_filled()
{
if (form_1.realname.value=="")
{
alert("Please enter your name")
form_1.realname.focus()
return false
}
if (form_1.subject.value=="")
{
alert("Please enter a subject")
form_1.message.focus()
return false
}
else
return true
};
function change_subject
{
form_1.subject.value="form_1.realname.value + '_' + form_1.subject.value"
};
</script>
</HEAD>
This is the FORM (used for MSA FormMail): Code: <form name="form_1"; onSubmit="return is_filled()"; on Submit="change_subject()"; method="post"; action="http://gb2gf.org/cgi-sys/FormMail.cgi">
<input type="hidden" name="recipient" value="drt@gb2gf.org">
<input type="hidden" name="required" value="greeting,realname,city_state,email_1,email_2,message">
<input type="hidden" name="sort" value="order:greeting,realname,city_state,email_1,email_2,message">
<input type="hidden" name="redirect" value="http://www.gb2gf.org/thanks.htm">
<!-- Input fields here -->

Thanks! Dr. T. My switch function just goes to the default. I've double double checked the file paths of the image on the page and it's right. So I'm not sure what's going on. here's what I got: Code: function change2(picName,imgName)
{
switch (document[picName].src)
{
case document[picName].src= "images/leaf_shapes/leaf_auriculate.gif":
document[picName].src = "images/leaf_shapes/crenate/leaf_elliptic_crenate.gif";
break;
case document[picName].src= "images/leaf_shapes/leaf_cordate.gif":
document[picName].src= "images/leaf_shapes/serrate/leaf_elliptic_serrate.gif";
break;
default:
document[picName].src= "images/leaf_shapes/transparent1.gif";
}
}
Hello, I've made a scrollable image gallery. I need the big image to pop up when the thumbnails are hovered over. It works fine in Firefox but in IE the big image fails to disappear when you take the mouse off the thumbnail. Please could someone look at this jquery code for me I am new to this someone made this for me but it really needs to work in IE too. Many thanks for your time emmamargaret <script type="text/javascript" src="http://cdn.jquerytools.org/1.2.5/jquery.tools.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $(".scrollable").scrollable({ vertical: true, mousewheel: true }); var container = $("#imagewrap"), content = $("#centrecontainer"); $(".items img").bind("mouseenter mouseleave", function(e) { var thumb = $(this); if (e.type == 'mouseenter') { container.css({backgroundImage: "url(http://www.emmagallagher.co.uk/" + thumb.attr("src") + ")"}); } else { container.css({backgroundImage: none }); } content.toggle(e.type == 'mouseleave'); }); }); var MM_swapImage = MM_swapImgRestore = function() {}; </script> I have this code that when you click a button it will shuffle items in an array then you have 10 seconds to read it then the array items disappear. But I need to figure out how to make it so that you can do something like click another button that will allow you to click the twister drill button again and it will shuffle it heres the code any help would be appreciated Code: <script type="text/javascript">
function myFunction()
{
var myarray=["red","blue", "yellow", "orange"]
myarray.sort(function() {return 0.5 - Math.random()})

I have a question: look at the following html code: /****html***/ <div class='class1'>text1</div> <div class='class1'>text2</div> <div class='class1'>text3</div> ...... /**html***/ If I want to change the background color of the textn by clicking it, what should I do instead of inserting "onclick='someFunction()'" in every div? I have a few tabs on my website. They're each set to the corresponding id in the JS file. It's supposed to add #tab-1 to the end of the URL in the users browser when it's clicked. For example, when a user is at mypage.com and they click on the tab, it ads mypage.com/#tab-1 to the end. How come it doesn't do what I want when I click it though? Here's an example of how it's setup. HTML: <a href="#tab-1" id="tab1">Text</a> JavaScript: document.getElementById("tab1").onclick = function(){ this.href += "#tab-1"; } This is a script which has a window slide down on the page and a user can choose yes/no to continue. It works in all browsers other than IE...any help please? If you need more info, please let me know.

I've got a form textarea on my site, which after being submitted is stripped by my php file. Then my javascript kicks in and does some analysis of the entered text. However everytime the user entered a hard return within the textarea my javascript gives me an error 'tekenreeks niet afgesloten' which means something like 'string is not closed'. Therefore I decided to replace all occurences of chr(10) and chr(13) with ok2 (just some random characters), I did this with php which worked fine, and I didn't get the javascript error. However I need to reshow the entered text (original) to the user, so I need to restore the old values. I tried Code: result.waarde.replace('ok2', 'chr(13)');
but it doesn't work, as it still displays ok2. I'm no expert in javascript, but how can I replace those characters by the hard returns? Oh yeah I'll show some more coding, perhaps the error can be found the Code: result.waarde.replace('mdw', 'chr(13)');container.innerHTML = result.waarde;
and in my html: Code: <div id='waarde' style="width:500px;"></div> Below is code using the onmouseover event, but it doesn't work. The only thing that appears in the status bar is the URL. What am I doing wrong? Code: <a href="http://codingforums.com" onmouseover="window.status='This is an OnMouseOver event'; return true" onmouseout="window.status=' '; return true">Put your mouse here to see status info change at bottom.</a> Hi! I'm new to JavaScript and I've done some small adjustments to my clients site, but it won't show properly in IE (the shadowbox js at least.). I thought js was accepted in all newer browsers. Do you have a quick fix or idea on why it doesn't work? You can view source on my site, I use mootools, and shadowbox/corners and rightclick blocker. Is it generally a 'bad thing' to use js in webpages I want everyone to view in the same way? I tried the same effects with CSS but it's not supported in the same way corss-browser, unfortunately. The 'no selection' CSS class I have on the site is also not accepted in IE. It's very annoying! http://santinacrolla.ihaarr.com/p thank you in advance! Heya, I wrote the following page in a day or two (please don't mind the layout). Everything seems to work excellent, apart from in Firefox (FF) in which it doesn't seem to work at all. None of the other browsers have any trouble with it. I'm pretty new to Javascript (everything you see in the source code is pretty much all I know) and I have absolutely no idea why it doesn't work in Firefox. The page in question could be found [link has been removed]. It's all there is to it. So yeah, how to actually make this work in FF? Thanks a whole bunch in advance! Much appreciated. Please see URL: http://caspca.org/indexticker.htm The ticker below the navbar works fine in FF and Safari, does not work in IE8 (and mostly likely other IE version as well). In IE, the live page will not even load; will load locally but the ticker doesn't work (remains static). Here is the .js: Code: TICKER_CONTENT = document.getElementById("TICKER").innerHTML;
TICKER_RIGHTTOLEFT = false;
TICKER_SPEED = 1;
TICKER_STYLE = "font-family:Arial; font-size:12px; color:#444444";

}
if(!tickerSupported) document.getElementById("TICKER").outerHTML = ""; else {
document.getElementById("TICKER").scrollLeft = TICKER_RIGHTTOLEFT ? document.getElementById("TICKER").scrollWidth - document.getElementById("TICKER").offsetWidth : 0;
document.getElementById("TICKER_BODY").innerHTML = TICKER_CONTENT;
document.getElementById("TICKER").style.display="block";
TICKER_tick();
}
}
function TICKER_tick() {
if(!TICKER_PAUSED) document.getElementById("TICKER").scrollLeft += TICKER_SPEED * (TICKER_RIGHTTOLEFT ? -1 : 1);
if(TICKER_RIGHTTOLEFT && document.getElementById("TICKER").scrollLeft <= 0) document.getElementById("TICKER").scrollLeft = document.getElementById("TICKER").scrollWidth - document.getElementById("TICKER").offsetWidth;
if(!TICKER_RIGHTTOLEFT && document.getElementById("TICKER").scrollLeft >= document.getElementById("TICKER").scrollWidth - document.getElementById("TICKER").offsetWidth) document.getElementById("TICKER").scrollLeft = 0;
window.setTimeout("TICKER_tick()", 30);

It is a aspx file and validates fine as XHTML Trans. Why won't it work? Hello, I'm new to javascript and html5. I've been having problems with some simple(?) lines of code. Code: var ctex;
var totalX = 400;
var totalY = 300;
var racpad = new Image();
racpad.src = 'Imgs/paddle.gif';
var brixadow = new Image();
brixadow.src = 'Imgs/brickLight.gif';
function initCnv()
{
canvas = document.getElementById('canvas01');
ctex = canvas.getContext('2d');
AppStep();
}
function clearcv(x)
{
ctex.clearRect(0, 0, totalX, totalY);
ctex.fillStyle = x;
ctex.beginPath();
ctex.rect(0, 0, totalX, totalY);
ctex.closePath();
ctex.fill();
}
function AppStep()
{
clearcv('black');
ctex.drawImage(racpad, totalX/2, totalY-50);

What I'm trying to do is to simply turn the canvas black and show a small gif on it. Upon executing initCnv(), the canvas turns black as it should, while the sprite image doesn't show up at all. I can't figure out what's going on, I scoured the code for syntax errors, even tried other image formats but to no avail. Image paths are also correct. Maybe the problem's an extremely noobish one, but I still couldn't get a clue, so I thought I'd ask for help around here. Thanks for your time! Ive searched on this board but cant find out why this doesn't work. Code: <script type="text/javascript">
function showSelected(val)
if (val == "Nil")
{
document.getElementById('JustText').innerHTML='hi'
}
else
{
document.getElementById('selectedResult').innerHTML="<a href='mailto:" + val + "'>" + val + "</a><p>"
}
</script>
Hi, doing form validation at college just now. The lecturer gave all of us this following example. But it doesn't seem to work in firefox. I have tried my own scripts and they seem to work so have no idea whats happening! Code: <html>

I'm having one of those moments right now. Can someone explain why the following alerts "undefined" instead of "George"? Code: function test(){
this.worker='George'
}
test.sayname=function(){
alert(this.worker)
}
test.sayname() //alerts "undefined"
I know I can get it to alert "George" by instantiating test(), but I thought the above should work even without doing that. |
