JavaScript - If Else Not Working, Alert Boxes

hye all,
it's me again. i have a little bit confusion here. why is this alert "alert("Please answer the question.");" did not prompt out even if i don't select any of the radio button?can anyone help me? i appreciate if someone can help me.TQ.

Here is the coding to return the radio buttons' value:

Code:

function getSelectedValue(flds) {
    var i = 0;
    var len = flds.length;
    
    while (i < len) {
    if (flds[i].checked) {
     return flds[i].value;
    }
    i++;
    }
    
    return "";
}

Below is the coding to calculate the radio button value:

Code:

var bdpr=0,bdft=0,bdbs=0,prft=0,prbs=0,ftbs=0;
var rank= new Array();
    var form = document.forms.Calculator;
    var bdpr = Number( getSelectedValue(form.elements.a) );
    var bdft = Number( getSelectedValue(form.elements.b) );
    var bdbs = Number( getSelectedValue(form.elements.c) );
    var prft = Number( getSelectedValue(form.elements.d) );
    var prbs = Number( getSelectedValue(form.elements.e) );
    var ftbs = Number( getSelectedValue(form.elements.f) );

    if ( isNaN(bdpr)|| isNaN(bdft) || isNaN(bdbs) || isNaN(prft) || isNaN(prbs) || isNaN(ftbs)){

    alert("Please answer the question."); }

else{
    brand=1+bdpr+bdft+bdbs;
    price=1+1/bdpr+prft+prbs;
    feature=1+1/bdft+1/prft+ftbs;
    basic=1+1/bdbs+1/prbs+1/ftbs;
  window.open("try.html");  
}

I have used this formula before, for some reason it isnt working properly. If the value is equal to 0 it will give an alert and return false. Then if you change the value of the drop down it won't let you submit.

Does anyone see anything wrong?

Code:

<script type="text/javascript">
<!--

function validate_form ( )
{
    valid = true;

    if ( document.week_picks.blowout.value == "0" )
    {
        alert ( "Please Select a Blowout" );
        
    }

    return false;
}

//-->
</script>

Code:

<form name="week_picks" method="post" action="confirm.php" onsubmit="return validate_form()">

<select id="blowout" name="blowout">
<option value="0">..</option>
....
</select>

Thanks for any help.

//The Javascript
// Functional Code -  NO NEED to Change
 
function f40_Disable(f40_par,f40_obj,f40_state){
 if (f40_par){f40_clds=f40_AllElements(document.getElementById(f40_par)); }
 else { f40_clds=f40_AllElements(f40_obj.parentNode); }
 if (!f40_obj.ary){
  f40_obj.ary=new Array();
  for (f40_0=0;f40_0<f40_clds.length;f40_0++){
   if (f40_clds[f40_0].tagName=='INPUT'||f40_clds[f40_0].tagName=='SELECT'||f40_clds[f40_0].tagName=='TEXTAREA'){
    f40_obj.ary[f40_obj.ary.length]=f40_clds[f40_0];
   }
  }
 }
 for (f40_1=0;f40_1<f40_obj.ary.length;f40_1++){
  f40_obj.ary[f40_1].removeAttribute('disabled');

Hi,
I have this code:

var finalsort="("+getvalue+","numvalue")\n"
alert(finalsort)

however, it is then alerted three seperate times (as it is in a for loop) but i would like this to be displayed in an alert:

(david,5)
(james,3)
(tom,1)

How would I do this, am I doing something wrong with the \n?
thanks

I am validating the value in a text area onBlur. If the value is not good the alert box comes up twice. Is there a way to correct this?
Code:

<html>
<head>
<meta http-equiv=Content-Type content="text/html; charset=ISO-8859-1">
<title>Untitled</title>

<script type="text/javascript">
function verify_score(val1)
{
var temp = document.getElementById(val1)

if(temp.value == "AF"|| temp.value == "HF" || (temp.value >=0 && temp.value <=17)) {return}
else{
alert("Value entered is not OK. Accetable values a  0 to 17, AF or HF")
temp.focus()
temp.select()
}
}
</script>
</head>
<body>

<div id="PageDiv" style="position:relative; min-height:100%; margin:auto; width:200px">
	<form name="scoresheetform" action="">
	
	<div id="Submitbutton" style="position:absolute; left:52px; top:87px; width:110px; height:33px; z-index:1">

All,
I have the following code:
Code:

<script type="text/javascript">
alert("This picture has received more then 10 down votes so it is now being deleted. You will be redirected back to the pictures page!");
</script>
<?
echo "<meta http-equiv=\"refresh\" content=\"2;url=http://website.com/pictures.php\">";
?>

This is just in the code. I thought it would just execute this but it doesn't. I can't have it appear on a button event or an onload since this snipped gets executed with AJAX. How can I make it appear?

Thanks in advance!

i need the system to think its getting an alert without actualy presenting an alert on the page.

i found this but i guess i dont really understand how it works

Code:

function foo() {
    doSomething();
    fakeAlert("Alert! Alert!", doSomethingAfterTheAlertIsCleared);
}

i hate to have to do hacks to get something to work but for some reason my simple js will not work without an alert

Code:

<script type="text/javascript">   
 <!--                          					    
   function process_acount()
   {     
    alert("about to send data");
    document.bbautoreg.submit();
    }
// -->
</script>

it works perfectly with the alert and the comment

if i remove the alert, it wont work, if i remove the <!-- it wont work, if i have the alert without the comment <!-- it wont work.

i thought maybe there might be something wrong with the js interpreter i even changed it from html to php using echo for the js and still the same

unless i can get this to work i will have no other choice but to use a fake alert

why would having an alert make a dif anyway, seems to me thats just crazy, that itself should have no bearing on if it executes or not. Anyone know why that would matter.

When you do an alert confirm you can make if statements to say if they click ok do this and if they click cancel stop the program. Well I am trying to make a prompt that first asks the user to enter in a url and after they do and click enter they url is wraped with img tags.

I would like to make it so that if the user clicks cancel the program ends b/c right now if the user click okay with no value the result is [img][/img] and if the user clicks cancel the result is [img]null[/img]. Any step in the right direction would be greatly appreciated!

PHP Code:
<script language="javascript">
  function imgGenerator(){
      var question=confirm("Would you like to share an image?");
      if (question==true){
         var obj=document.getElementById("mngl-board-post-input");
         var imgurl = prompt("To Share an image paste the image url here");
         var txt=document.createTextNode("[img]"+imgurl+"[/img]");
         obj.appendChild(txt);
      }
      else {}
  }
  </script> 

The alert at the top of this function will not show...

Code:

function getXmlHttpRequestObject() {
    alert("HTTP XML REQUEST!");
    var httpxml;
    if (window.XMLHttpRequest)
      {
         // code decent browsers like Firefox, Chrome, Opera, Safari. And IE7+...
          httpxml = new XMLHttpRequest();
        return httpxml;
      }
      else {
          if (window.ActiveXObject) {
            //Code for crap like IE
              httpxml = new ActiveXObject('Microsoft.XMLHTTP');
            return httpxml;
        }
        else {
            httpxml = null;
        }
      }
     if (httpxml == null) {
        document.getElementById('p_status').innerHTML = "Status: Could not create XmlHttpRequest Object, 
                                                     please upgrade your browser!";
        return null;
     }
    else {
    return httpxml;
}

Hi!

I've seen several sites that use what looks like the alert function (I know it isn't), where the site gets darkened and a popup box (similar to that of the alert one) comes up and displays an image (and only an image) ... how is this done?

Regards
Matthew

This is all php except for the java code I am struggling with. Please advise.

I have tried this 2 ways and have spent hours on something that should be simple.

I have a string that I am trying to display in an alert box with an onclick

method 1:

$mystring = "<a href=\"mysite.com\">Click</a>";

this does not work

echo "<input type='button' value='Grab Code' onClick=alert('$mystring')>";

nor does this

echo "<input type='button' value='Grab Code' onClick=alert('".$mystring."')>";

nor does anything I try. All I want to do is display the value of mystring in an alert box.

However, this does work ..

echo "<script type='text/javascript'> alert('".$mystring."');</script>";

But I cannot call this from an onclick.

Any help is appreciated.

Thanks

JT

How would you make a alert box that contains a tabel instead of writting?

thanks this problem has been solved

Hey!

First off you guys rock! Second im a massive noob - like beyond noob.

Ok so heres the deal guys and gals:
I use Kampyle (a feedback form thing) and when my viewers click my feedback button a new window pops up and is the form.

Like this (plus thats my site if you want to try it):


However! theres this site (yes my arch enemy, well were actually two different things and hey i dont even speak their language) and they use the same feedback thing by Kampyle too. But the catch is theirs is inbuilt. something like Lightbox Javascript but for forms/windows. or Facebook's popup notices?

so theirs looks like this:


This make me ANGRY!!! cause i want that and ive had to ask stupid people cause you guys and gals are way too advance for me... well i am only 17... anywho...

WHO CAN HELP ME???

if you want to test the difference between the two forms,
my site: that creative corner and click the feedback button.
their site:Lyoness and click the feedback button in the bottom right corner.

THANK YOU SO MUCH!!!
