JavaScript - Issue In Displaying Nan Values

I have a bunch of checkboxes like below that the user can check some or all and click the button and see the values of all the selected checkboxes. How can I do that?

Code:

<script>
function alertValues(){


}
</script>


<input type="checkbox"  class ="normal2" value="131971" name="list[]" >
<input type="checkbox"  class ="normal2" value="131973" name="list[]" >
<input type="checkbox"  class ="normal2" value="131975" name="list[]" >
<input type="checkbox"  class ="normal2" value="131977" name="list[]" >

<input type="button" onClick="alertValues()"

Hi,
What's a good way/ideal data structure to achieve this?

The objective of the code/function is to map user-inputted strings into a pair of specific, hard-coded strings. For example, say the user types "firefox" or "ff", or "fx". The output would be the pair ["browser", "mozilla"], for example.

I'm currently using a multidimensional array, but it feels inefficient and I'm having trouble mapping an arbitrary number of inputs into 2 outputs.

Code:

var strings = [ ["input1", "output1a"],
                ["input2", "output1a"],
                ["input3", "output1a"],
                ["input1", "output1b"],
                ["input2", "output1b"],
                ["input3", "output1b"]
              ];

How should I map the elements ["input1", "input2", "input3"] => ["output1a", "output1b"] ?

Another method I used previously was a massive switch statement. This fulfills my needs, but I'm not sure about the efficiency (though if I remember correctly, switch statements become more efficient as size grows, since it uses a hash table?).

Code:

switch (input) {
    case "ff": case "firefox": case "fx" : case "ffox":
        return ["browser", "mozilla"];
    case "ie": case "internet explorer":
        return ["browser", "microsoft"];
    ...
}

Hello,

for some reason this code isnt showing anything:

Code:

<span id = "message" style="color:black; font-size:12pt; font-family:arial,verdana,sans-serif"></span>
<script type = "text/javascript">

var targetURL="#";
var countdownfrom = 10;
var currentsecond = countdownfrom +1;
function countredirect() {
if (currentsecond !=1 ){
currentsecond -=1;
var mess = "You will be redirected to Points2shop in " + currentsecond + " seconds.";
document.getElementById("message").innerHTML = mess;
}
else{
window.location=targetURL;
}
setTimeout("countredirect()",1000);
}

countredirect();

</script>

ive tried:

Code:

<form name="message">
<span id = "message" style="color:black; font-size:12pt; font-family:arial,verdana,sans-serif"></span>
</form>
<script type = "text/javascript">

var targetURL="#";
var countdownfrom = 10;
var currentsecond = countdownfrom +1;
function countredirect() {
if (currentsecond !=1 ){
currentsecond -=1;
var mess = "You will be redirected to Points2shop in " + currentsecond + " seconds.";
document.getElementById("message").innerHTML = mess;
}
else{
window.location=targetURL;
}
setTimeout("countredirect()",1000);
}

countredirect();

</script>

Anyone know why?

Thanks

Hi,

I am trying to display some xml elements that are formatted like this:

Code:

<line>
<route>
<dirs>1.	Head west on Calzada Roosevelt</dirs>
<time>4.6 km - about 15 mins</time>
<dirs>2.	Continue on Carretera Interamericana/Pan American Hwy</dirs>
<time>15 km - about 12 mins</time>
<dirs>3.	Look for turnoff at San Lucas and follow signs from there</dirs>
<time>13.5 km - about 15 mins</time>
</route>
</line>

using this js:

Code:

for (var a = 0; a < lines.length; a++) {
routeInfo = lines[a].getElementsByTagName("route");
               for (var p = 0; p < routeInfo.length; p++) {
                  var time = GXml.value(routeInfo[p].getElementsByTagName("time")[0]);
                  var dirs = GXml.value(routeInfo[p].getElementsByTagName("dirs")[0]);

    way+='<b>'+dirs+'</b>'+'<br>'+time+'<br>';

("way" eventually gets passed as the text to display)

Which works OK (as you can see here if you select from Guatemala City to Antigua), but the problem is that it only shows the first set of directions, ie
Code:

<dirs>1.	Head west on Calzada Roosevelt</dirs>
<time>4.6 km - about 15 mins</time>

I can see that this is because of the [0] in the getElementsByTagName - if I change it to 1 or 2 it shows the 2nd or 3rd set of directions. But I want it to show all of them... and I thought that being in a loop it would, but I'm obviously missing something. Any ideas? Thanks in advance.

I'm not sure if java is the best way to go with this, I'm pretty inexperienced with java, but I have a workable knowledge of html, and couldn't see a way to do it that way... so here goes:

For my job I work with a ton of different deadlines all the time. What I want to do is to make a webpage that displays the date N days ago, and N days into the future. So something like 7 days ago, 30 days ago, 60 days ago 75 days ago, 30 days from now, 60 days from now, 75 days from now. etc. I've found brief snippets for how to display today's date, but i'm having trouble with the calculations. Then I also need one that displays 18 years ago, I'm not sure if the change from days to years makes any kind of difference, but I suppose it's easy enough to convert years to days anyway....

How would I go about doing that?

Thank you!!!

I am having a problem with my homework displaying an iframe using JavaScript.
My homework states:

Insert a script element that does the following:

part a. Insert the following multiline comment:
Display the daily schedule in an inline frame. Daily schedules are stored in the files
sunday.html through saturday.htm.

part b.
Insert a command to write the HTML code
<iframe src="weekday.htm'></iframe>

to the Web page, where weekday is the text string returned by the weekDay() function.

What I have so far:
<script type= "text/javascript">
/* Display part a */

document.write("<iframe src='weekday.htm'></iframe">;
</script>

My Question:
How do I display weekday.htm within my script on a specific day using the function weekDay() function.

below is my weekDay() function:
function weekDay(){
thisDate = new Date();
var thisWDay=thisDate.getDay();
var wdName = new Array("sunday", "monday", "tuesday", "wednesday",
"thursday", "friday", "saturday");
return wdName[thisWDay];
}

I wrote a function (shown below) that is to take numbers from <div> tags add them up and display the value in a different <div> tag. It also prints the total in a hidden input tag to be sent when submitted.

All was working fine until today I noticed that the total was no longer showing up in either the <div> tag or the hidden input tag.

on change of any of the select menus correctly displays the expected value in its corresponding <div> tag

I have no Idea what might be causing this, so I need fresh eyes.
(My JavaScript skills are way below my php skills, I can't see anything wrong with what I have)

PHP Code:
// I am using a php function that spits out these 
// (one for each item listed in the  JS function:
<select name="body" onchange="document.getElementById('total_body').innerHTML = this.options[this.selectedIndex].getAttribute('cost_body');calcTotal();" id="frm">
    <option value="2" cost_body="0">2</option>
    <option value="3" cost_body="10">3</option>
    <option value="4" cost_body="20">4</option>
    <option value="5" cost_body="30">5</option>
    <option value="6" cost_body="40">6</option>
    <option value="7" cost_body="65">7</option>
</select>

//Which displays in:
<div id="total_body">0</div>

//AND Calls this JavaScript Function:

<script type="text/javascript"> 
function calcTotal(){
    var numVal1=parseInt(document.getElementById("total_body").innerHTML);
    var numVal2=parseInt(document.getElementById("total_agility").innerHTML);
    var numVal3=parseInt(document.getElementById("total_reaction").innerHTML);
    var numVal4=parseInt(document.getElementById("total_strength").innerHTML);
    var numVal5=parseInt(document.getElementById("total_charisma").innerHTML);
    var numVal6=parseInt(document.getElementById("total_intuition").innerHTML);
    var numVal7=parseInt(document.getElementById("total_logic").innerHTML);
    var numVal8=parseInt(document.getElementById("total_willpower").innerHTML);
    var numVal9=parseInt(document.getElementById("total_edge").innerHTML);
    var numVal10=parseInt(document.getElementById("total_magic").innerHTML);

    var totalValue = numVal1 + numVal2 + numVal3 + numVal4 + numVal5 + numVal6 + numVal7 + numVal8 + numVal9 + numVal10;

    document.getElementById("grand_total").innerHTML = totalValue;
    document.getElementById("point_total").value = totalValue;
}
</script>

//Which until today had been displaying in:
<div align="center" id="grand_total">0</div>

//AND 
<input type="hidden" name="point_total" value="" id="point_total"> 


Here is a page that shows what it is (not) doing. http://rpg.5150press.com/test.php

I can't seem to get my innerHTML to display my content.

This works fine, if I was to put it all in one line.
Code:

document.getElementById('addedText').innerHTML =  '<table><tr><td>'+"My text goes here"+'</tr></td></table>';

If I was to break it up, which I wanted then nothing seem to show up.
Code:

   document.getElementById('addedText').innerHTML = '<table><tr><td>';
   document.getElementById('addedText').innerHTML = "My text goes here";
   document.getElementById('addedText').innerHTML = '</tr></td></table>';

Here's my code
Code:

<html>
<head>
<script type="text/javascript"> 
function display() {
   document.getElementById('addedText').innerHTML = '<table border=1><tr><td>';
   document.getElementById('addedText').innerHTML = "My text goes here";
   document.getElementById('addedText').innerHTML = '</tr></td></table>';
}
</script>
</head>

<body onload="display()">
<div id="addedText"></div>
</body>
</html>

thanks

Hello all,

I'm trying to create a sub menu that displays based on what the user clicks on the main nav.

Here's an image of what I'm trying to accomplish. The main nav is at the top right corner, when the click on one of the links, I want the sub nav to display in the gray area....how would I do this.

Would it be through an if/else statement using document.getElementById with inner HTML? Or would there be a better way. I'm really trying to do this by myself, so please don't do it for me...just give me a couple of suggestions if you don't mind. THanks

Hello all,

I need your help. I know what I'm trying to do, just having a difficult time getting started. I want to display the user-name of an individual when they login. I know how this can be doing using php, but what about javascript?

Ex:

username: __________
password: __________

After Login:

Welcome ['username']

I hope that makes sense.

Thanks in advance

I thought I knew how, but I'm unclear how to get this function to display: "document.getElementById("txtHint").innerHTML=xmlhttp.responseText;" inside the div. Will you show me please?

Code:

xmlhttp.onreadystatechange=function() {
    if (xmlhttp.readyState==4 && xmlhttp.status==200) {
      var div = document.createElement('div');
      div.setAttribute('id', 'txtHint');
      div.setAttribute("style","background-color:red;");
      div.style.width = '300px';
      div.style.height = '100px';
      document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
      //var txt='hello world!';
      document.getElementsByTagName('body')[0].appendChild(div);
      document.getElementById('textHint').innerHTML=txt;
    }
  }

Hi,
I've got this bit if JavaScript that loads a Flash applet. It also has a noscript tag in case the user has JavaScript turned off.
Works great in all browsers I've tried, but it doesn't work at all in IE8 (nor IE7 emulated). Even the noscript content isn't showing up.
W3C validator shows no issues.
No little exclamation point warning in IE's bottom-left corner.
I've even tried lowering the browser security with no change -- but that wouldn't have been a good solution if it had worked anyway; I can't tell my visitors to lower their browser security.

Any ideas of suggestions?
Thanks for any help!

I am creating a script to display some variable but it won't work. Did I do something wrong?

Code:

<script type="text/javascript">
/* <![CDATA[ */


var yotta = le24;
var zetta = le21;

document.write("<table border='1' width='100%'><tr><th>Prefix</th><th>Decimal Equivalent</th></tr>");
document.write("<tr><td>Yotta</td><td>" + yotta + "</td></tr>");
document.write("<tr><td>Zetta</td><td>" + zetta + "</td></tr>");
document.write("</table>");


/* ]]> */

</script>

Everything looks right, I think. Anyone see something wrong?

Thank you, I am a firefighter of 25 years.

Problem/Error: JavaScript/AJAX not returning values correctly...

The JavaScript/AJAX is printing "null" into the chat_div where the tag name is "user". But in those tags there is actually data, this data is a link. I am thinking that it may be returning the first childNode which would be the <a>? I don't fully understand nodes, but I have had a quick read about them.

    </message>
    <message id="2">
