JavaScript - Looking For A Explanation To The Following Problem?

I am learning javascript from this site, and one of the programs code given is now explained to the point that I can not use it. I don't know how to call it. I would be glad if someone would examine the code to see how it should be applied.

Hi pals,
I am really tired in this problem of event keyup. I given same in my keyup function like:

$(document).ready(function () {
alert("GGG"+parseInt(jQuery.browser.version)); //To display test value working
$("#find_text").keyup(function(e)
{
if(e.which == 13) {
alert('Enter key was pressed'); //enter Here
alert("FFF"+parseInt(jQuery.browser.version)); //Here got Error
}
});
});

I got Error : jQuery is not defined
alert("FFF"+parseInt(jQuery.browser.version));

I use keycode,which , but no help, It's Work nicely in Chrome Browser but not in FF.
Please give a Solution reply ASAP, I am really Tired.The code enter the Condition
But that jQuery part make error.

Anes P.A

Hi, i can't get my new logo to work in IE, it's working fine in Chrome and FireFox, it must be a JavaScript problem.

here it is:
http://danishwebart.com/logo/logo.php

And the JavaScrip:

$(function() {
var canvas = $("#c");
var canvasHeight;
var canvasWidth;
var ctx;
var dt = 0.1;

var pointCollection;

function init() {
updateCanvasDimensions();

var g = [new Point(27, 34, 0.0, 1, "#ed9d33"), new Point(26, 38, 0.0, 1, "#d44d61"), new Point(25, 41, 0.0, 1, "#4f7af2"), new Point(22, 44, 0.0, 1, "#ef9a1e"), new Point(18, 46, 0.0, 2, "#4976f3"), new Point(12, 44, 0.0, 2.5, "#269230"), new Point(7, 41, 0.0, 2, "#1f9e2c"), new Point(5, 37, 0.0, 1, "#36b641"), new Point(4, 33, 0.0, 1, "#2e5def"), new Point(4, 29, 0.0, 1, "#d53747"), new Point(5, 25, 0.0, 1, "#eb676f"), new Point(6, 22, 0.0, 1, "#f9b125"), new Point(8, 19, 0.0, 1, "#de3646"), new Point(11, 16, 0.0, 1, "#5f8af8"), new Point(13, 14, 0.0, 1, "#efa11e"), new Point(16, 12, 0.0, 1, "#2e55e2"), new Point(19, 10, 0.0, 1, "#4167e4"), new Point(23, 8, 0.0, 1.5, "#4869e3"), new Point(28, 6, 0.0, 2, "#10a11d"), new Point(33, 5, 0.0, 2, "#cf4055"), new Point(38, 5, 0.0, 2, "#cd4359"), new Point(44, 6, 0.0, 3, "#ca273c"), new Point(51, 8, 0.0, 3, "#2650e1"), new Point(57, 11, 0.0, 3, "#4a7bf9"), new Point(63, 16, 0.0, 3.5, "#f47875"), new Point(68, 23, 0.0, 4, "#f36764"), new Point(71, 31, 0.0, 3.5, "#1d4eeb"), new Point(72, 38, 0.0, 3, "#698bf1"), new Point(72, 44, 0.0, 2.5, "#fac652"), new Point(72, 49, 0.0, 2, "#ee5257"), new Point(71, 54, 0.0, 2, "#5681f5"), new Point(70, 59, 0.0, 2, "#f8c247"), new Point(68, 64, 0.0, 2, "#4577f6"), new Point(65, 68, 0.0, 2, "#f7b326"), new Point(62, 72, 0.0, 2, "#facb5e"), new Point(59, 75, 0.0, 2, "#e02e3d"), new Point(55, 77, 0.0, 2, "#f16d6f"), new Point(53, 78, 0.0, 2.5, "#507bf2"), new Point(47, 79, 0.0, 3, "#5683f7"), new Point(40, 77, 0.0, 3.5, "#3158e2"), new Point(33, 74, 0.0, 3.5, "#f0696c"), new Point(27, 73, 0.0, 2.5, "#3769f6"), new Point(22, 73, 0.0, 2, "#6084ef"), new Point(19, 76, 0.0, 1.5, "#2a5cf4"), new Point(17, 79, 0.0, 1, "#f4716e"), new Point(25, 70, 0.0, 2, "#f8c247"), new Point(29, 67, 0.0, 2, "#ec4147"), new Point(33, 64, 0.0, 2, "#4876f1"), new Point(36, 59, 0.0, 2.5, "#2552ea"), new Point(38, 53, 0.0, 3, "#4779f7"), new Point(38, 46, 0.0, 3.5, "#4b78f1"), new Point(38, 38, 0.0, 3.5, "#4b78f1"), new Point(37, 31, 0.0, 2.5, "#4b78f1"), new Point(38, 25, 0.0, 2, "#4b78f1"), new Point(40, 20, 0.0, 2, "#4b78f1"), new Point(42, 16, 0.0, 1.5, "#4b78f1"), new Point(45, 14, 0.0, 1, "#4b78f1"), new Point(48, 12, 0.0, 1, "#4b78f1"),

I am creating a page which redirects automatically depending on the date.

What I've done so far is below, but how would I make it go switch to exceeded_year.htm on 25th March 2011 for example?
I will also include other dates and later put this page in a header frame and controlling the frame below so its constantly open.
<html>

<script type="text/javascript">
<!--
var currentTime = new Date()

var date = currentTime.getDate()
var month = currentTime.getMonth() + 1
var year = currentTime.getFullYear()

if (year > 2011 ) {window.location = "exceeded_year.htm"; }

else window.location="#"

//-->
</script>

</html>

Hi,

so I thought I could mash two bits of code together like this:

Code:

<div><label for="or">From:</label>
<select name="or" style="width:200px; float: right" id="or" onchange="populate(this)">
  <option value="Choose">Select your starting point</option>
  <option value="Guatemala">Guatemala City</option>
  <option value="Xela">Quetzaltenango</option>
  <option value="Antigua">Antigua</option>
  <option value="Rio Dulce">Rio Dulce</option>
  <option value="Coban">Coban</option>
</select></div>
<div>
<label for="de">To:</label>
<select name="de" style="width:200px; float: right" id="de"></select>
</div>
<div>
<br>
<input type="button" onclick="searchLocations()" value="Show route" />
</div>
			</div> 
			</div>
        </div>
	


<script type="text/javascript">
    if (GBrowserIsCompatible()) {
		var gpolylines = [];

function populate(o) {
  d=document.getElementById('de');
  if(!d){return;}                 
  var mitems=new Array();
  mitems['Choose']=[''];
  mitems['Guatemala']=['Select Destination','Antigua','El Rancho junction','San Pedro La Laguna','Panajachel','Coban','Rio Hondo','Chiquimula','Esquipulas','Copan Ruinas (Honduras)','La Ruidosa junction','Rio Dulce','Flores (via Rio Dulce)','Puerto Barrios','Flores (via Coban)','Quetzaltenango'];
  mitems['Xela']=['Select Destination','Guatemala City','Antigua','Chichicastenango','Huehuetenango','Panajachel','San Pedro La Laguna'];
  mitems['Antigua']=['Select Destination','Guatemala City','Quetzaltenango','Escuintla','Monterrico','San Pedro la Laguna','Panajachel','Chichicastenango'];
  mitems['Rio Dulce']=['Select Destination','Guatemala City','Flores','Lanquin','Coban','Puerto Barrios'];
  mitems['Coban']=['Select Destination','Lanquin','Rio Dulce','Laguna Lachua NP','Flores'];
  d.options.length=0;
  cur=mitems[o.options[o.selectedIndex].value];
  if(!cur){return;}
  d.options.length=cur.length;
  for(var i=0;i<cur.length;i++) {
    d.options[i].text=cur[i];
    d.options[i].value=cur[i];
  }
}

 
 function searchLocations() 
{
    var found = false;
    var from = document.getElementById('or').value;
	var to = document.getElementById('de').value;
    for (var a = 0; a < gpolylines.length; a++) 
    {
        if (gpolylines[a].myname.toLowerCase() == to.toLowerCase() && gpolylines[a].mycategory.toLowerCase() == from.toLowerCase()) 
        {
            found = true;
            gpolylines[a].show();
        }
    }
    if ( ! found ) alert("No matches found. Please check your spelling or refine your search.");
}

the first bit, which populates the select boxes works fine, as you can see here

but the second bit (the searchLocations function) is giving me a bit more trouble. What it's supposed to be doing is saying that if there's a polyline whose category xml attribute matches the text from the 1st select box AND whose name attribute matches the 2nd select box, it should be shown.

The methods have worked in the past, there are no errors reported - the only problem is I get the alert regardless of which option I am selecting.

I suspect that the problem is in the if (gpolylines[a].myname.toLowerCase() == to.toLowerCase() && gpolylines[a].mycategory.toLowerCase() == from.toLowerCase()) line, as it's the only one that I really came up with on my own... or can I not get the "or" and "de" elements in that way? Or is it something else entirely?

thanks in advance for any suggestions...

I have looked at this for an hour and i can not find anything wrong

This is a program that calculates discriminant/number of solutions for a given quadratic equation.. it all works, but the number of solution field is not filled, so i think i did something wrong on my if else statements for it.. help!


Code:

<html>
<head>
  <title>Untitled</title>
</head>
<script type="text/javascript">
<!--    Begin
    function quad(form) {
    a = form.a.value
    b = form.b.value
    c = form.c.value
    form.Dis.value = (b * b) - (4 * a * c)
    If(form.Dis.value > 0)
    {
        form.NumSol.value = 2
    }
    Else;(form.Dis.value = 0)
    {
        form.NumSol.value = 1
    }
      Else
    {
        form.NumSol.value = 0
    }
   
    }
// End -->
</script>

<body><center>
<form name="form1">
<input type="text" name="a" size=5>
x^2 +

<input type="text" name="b" size=5>
x +

<input type="text" name="c" size=5>

<input type="button" value="Calculate"
onClick="quad(this.form)">

Discriminant: <input type="text" name="Dis" size = 7 />
Number of Solutions: <input type="text" name="NumSol" size = 7 />

hi i found some javascript on the internet that seemed to do what I wanted to achieve but cannot get it to work

when the mouse is over the image it should show a bigger image. I've used the internet explorer debugger and there seems to be problem in the code, but i dont understand javascript programming. Im a php man myself.

all the script is enclosed in this page

http://www.web-malta.com/testimage.html if you put the mouse over the photo you will see there is an error on the page.

hope someonbe can help.

cheers

this is coder javascript :
textneu = textneu.replace(/haha/,"<img src='../images/21.gif'>");

Result:
&lt;img src='../images/21.gif'&gt;

why?

i want result is :
<img src='../images/21.gif'>

Scratch that, its started working...

oh well haha

I really don't even know if I'm posting this question in the right section. I am using javascript to make a drop-down menu for a website. I really don't have any experience with javascript. The problem I'm having is that when I go to the page, the drop down menu is already dropped down. If you then hover over it, it pulls up and then hover over it again and it drops back down. It works fine after the initial glitch. Didn't know if anyone had run into this problem or if I'm just being stupid, here is the code that I'm using. Thanks in advance for any help.

Hey guys! :-)
How do i translate this javascript sentense in to "real working" javascript.

PHP Code:
if(a1 "its a box/this is just for info" = got a value written){

c1 also a box = disabled;

} 


How do i write this so it works?

My first thought was:

PHP Code:
if(document.GetElementById(a1).value = true){

document.GetElementById(c1).disabled = true;

} 



But cant get it working - is there somebody there could help me? :-)

Ok, I today installed IE9 and now my site has lost the main menu. The problem lies in my application.js file code below, any ideas on what may have caused this? When debugging in VS2010 it throws therror at the line prettyPrint(); with the error prettyPrint is underfined? I havent changed anything other than move browser from ie8 to ie9



Code:

var submitting = false;

$(function(){

    error: function(x, s, t) {
      //alert(error_message);
    },
    complete: function(){submitting = false;}
  });
});


$(window).load(function () {
  // Prittify
  prettyPrint();
});
