JavaScript - Factoring Code Doesn't Work
Code:
var f = [];
for ( var f1 = 1; f1 <= n; ++f1 )
{
var f2 = n / f1;
if ( f2 == Math.floor(f2) )
{
f.push(f1);
f.push(f2);
}
if ( f2 <= f1 ) break;
}
f.sort();
Someone helped me make this factoring code, but if n = 6, it returns [1,2,2,3,3,6,6,6] Any ideas? I am looking for [1,2,3,6] Similar TutorialsHey guys, noobie here. I created a page with a thumbnail viewer. Click on a thumbnail and a larger version appears on the same page, NOT a pop up or Lightbox. It previews and validates fine. Even runs in IE. But not in FF(V. 3.6.18). Ideas? Code below with JS highlighted.

I'm new to the forum. So hi everyone. The code below works fine on IE and FF but not on Google Chrome. Can someone tell me where I'm doing wrong? Thank you for your answers in advance. Im really looking forward much to hearing from you.

I have finally finished my factoring quadratics page! You can see it he http://wdroom.com/factor.html If you see that you received an incorrect solution PLEASE let me know so I can fix it. Credits: Old Pendant, Philip M, bullant in no particular order Thanks so much! 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.

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;

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> 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. 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! Code: <html>
<head>
<script>
function color() {
var newColor=new Array('#00f','#f00','#ff0');
var i=0;

It should make the first blue, second red, and third yellow yes? Hi! 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">

Thanks! Dr. T. 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>
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";
}
}
I have the following script in the head; Code: <script type="text/javascript">
<![CDATA[
<!--This function validates the data from the three input boxes on the MAILTO form-->
function validate()
{
Check="Valid";
Name=document.contact.name.value;
Mail=document.contact.mail.value;
Comment=document.contact.comment.value;
if (Name=="your name" || Name.length<1)
{
alert("Please enter your name");
Check="Invalid";
}
else if (Mail.indexOf("@")<1 || Mail.indexOf(".")<1)
{
alert("Please enter a valid email address");
Check="Invalid";
}
else if (Comment=="your comment" || Comment.length<1)
{
alert("Please enter your comment");
Check="Invalid";
}
if (Check=="Invalid")
{
return false;
}
else
{
alert("Thank you for your comment");
}
}

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>

Can someone see my error? I'm a bit rusty at my javascript. i am using the following code to set the height of the div based on its contents. it works fine in IE but not in mozilla. Do anybody help me to solve this? <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script type="text/javascript"> function fnCheckScroll() { document.getElementById('btnCheck').innerHTML = "The value of scrollHeight is: " + oID_1.scrollHeight + "px"; } function fnSetHeight() { oID_1.style.height = oID_1.scrollHeight; return false; } </script> </head> <body> <form id="form1" runat="server"> <div> <h1>scrollHeight Property Sample</h1> <p>This sample demonstrates the use of the <b>scrollHeight</b> property to retrieve the height of the viewable content.</p> <div id="oID_1" style="overflow: scroll; height: 200px; width: 150px; text-align: left"> The <b>scrollHeight</b> property is read-only, allowing you to obtain the actual height of the scrollable content. Even though the height of this <b>div</b> is 200 pixels, the height inside the scrolling text box might be less, since the wrapped text may not use the entire area within the object. The <b>scrollHeight</b> dimension may be useful for a variety of reasons; for example, the height of the <b>div</b> could be set to the <b>scrollHeight</b> to conserve horizontal space while respecting the set width as a maximum. </div> <p><button id="btnCheck" onclick="fnCheckScroll()">Check scrollHeight </button></p> <p><button id="btnSetIt" onclick="return(fnSetHeight());">Set DIV height to scrollHeight </button></p> <!-- START_PAGE_FOOTER --><br> <br> <br> </div> </form> </body> </html> |
