JavaScript - Javascript - New Array Via Prompt
I am new to learning JS and am trying to create an array through a prompt. It seems to work, but I believe it is treating the prompted numbers as strings not numbers. I am parsing the negatives and zeros, and positives and counting them. It doesn't recognize the negative sign.
Here's my js: function counter() { var numArr = new Array(Number(prompt("Please enter and array of numbers, in any order, separated by a comma..." + '\n' + "In the following format: -2,0,2"))); var positives = 0; var negatives = 0; var zeros = 0; for (var i = 0; i < numArr.length; i++) { switch (true) { case numArr[i] < 0: negatives++; break; case numArr[i] == 0: zeros++; break; case numArr[i] > 0: positives++; break; } } alert("You entered:"+ '\n' + "Number of Negatives: " + negatives + '\n' + "Number of Zeros: " + zeros + '\n' + "Number of Positives: " + positives); } counter(); Any suggestions? Similar Tutorialsmy assignment ----------------------------------- write a while loop that prompts user to enter name add their names to an array if they enter "exit" end the prompting sort array and list in sorted order ----------------------------------- this is what i got so far. sooo confused because i cant get the user input into an array. error console says i need ";" before the "var names[loopCounter] = prompt("enter","");" confused about this also var names = new Array(); var loopCounter; loopCounter = 0; while (names != "exit") { var names[loopCounter] = prompt("enter name",""); loopCounter++ } var i; names.sort(); for (i=0;i<names.length;i++) { document.write(names[i] + "<br>"); } Hi.. I should warn, i know almost nothing about javascript. . i've been trying read sample scripts and examples on how to modify this script; but I just don't know enough. I have a script that pulls data from an array, and copies it directly to the clipboard when a user clicks on it. The problem is this only works in IE, because Firefox doesn't by default allow that to happen. I'm trying to change it so that when it is clicked, instead, it takes what was going to be copied to the clipboard, and puts it in a Prompt box for the user to copy and paste. I had other scripts that do that, but I can't for the life of me figure out how to learn from it! This is the function in the current script Code: <script language="javascript" type="text/javascript">
<!--
function selectThis(src) {
document.selection.clear;
txt = eval(src +".innerText");
theObj = document.all(txt);
txtRange = document.body.createTextRange();
txtRange.moveToElementText(eval(src));
txtRange.select();
txtRange.execCommand("RemoveFormat");
txtRange.execCommand("Copy");
alert(txt + " '.$caption[ 'paste' ].'");
}
-->
</script>
';
}
and this is the onclick code Code: ';
foreach ( $ausgabe as $key => $data) {
if ( $key == '' )
continue;
if ( ( $_GET[ 'group' ] != '*' )
&& ( $this->info[ $key ][ 'xx_data' ] != $_GET[ 'group' ] ) )
continue;
$tpack = $this->info[ $key ][ 'pack' ];
$tname = $this->info[ $key ][ 'xx_desc' ];
$jsid= $nick2.'_'.$tpack;
if ( isset( $this->info[ $key ][ 'xx_lock' ] ) ) {
if ( $this->hide_locked > 0 )
continue;
$tname .= ' (gesperrt)';
}
$tname = htmlspecialchars( $tname);
if ( $javascript > 0 ) {
$tname = '<span class="selectable" onclick="javascript:selectThis(\''.
$jsid.'\');">'.
$tname."</span>\n".
'<span id="'.$jsid.'" class="hidden">'.
'/msg '.$this->nick.' xdcc send '.$tpack."</span>\n";
}
if ( isset( $this->info[ $key ][ 'xx_note' ] ) )
$tname .= '<br>'.$this->info[ $key ][ 'xx_note' ];
$label = "Download mit:\n/msg ".$this->nick.' xdcc send '.$tpack."\n";
if ( isset( $this->info[ $key ][ 'xx_md5' ] ) )
$label .= " \nmd5: ".$this->info[ $key ][ 'xx_md5' ];
if ( isset( $this->info[ $key ][ 'xx_crc' ] ) )
$label .= " \ncrc32: ".$this->info[ $key ][ 'xx_crc' ];
echo '
<tr>
<td class="right">#'.$tpack.'</td>
<td class="right">'.$this->info[ $key ][ 'xx_gets' ].'</td>
<td class="right">'.makesize($this->info[ $key ][ 'size' ]).'</td>
<td class="content" title="'.$label.'">'.$tname.'</td>
</tr>

I've spent days at trying to customize it.. but.. i'm not a programmer I was able to get it to open a prompt box, and had it populate with ("copy this code", $variable), but cannot figure out how to have it display the proper values that was clicked on. I have no idea though what is considered efficient either in the code. I hope this isn't considered asking for TOO much help.... I am trying to get these prompt boxes to display for age and resting heart rate. I cannot get this to work...This is what I have...any suggestions? <html> <head> <h1>Calculate Your Target Heart Rate</h1> <p>You can calculate your heart rate so that you can get the maximun results from your cardiovascular workout.

I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form. For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields. php array creation: Code: if ($row_locations)
{
while ($row_locations = mysql_fetch_assoc($locations))
{
$mail[$row_locations['comp_id']]=array('mailto'=>$row_locations['mailto'], 'madd'=>$row_locations['madd'], 'madd2'=>$row_locations['madd2'], 'mcity'=>$row_locations['mcity'], 'mstate'=>$row_locations['mstate'], 'mzip'=>$row_locations['mzip'], 'billto'=>$row_locations['billto'], 'badd'=>$row_locations['badd'], 'badd2'=>$row_locations['badd2'], 'bcity'=>$row_locations['bcity'], 'bstate'=>$row_locations['bstate'], 'bzip'=>$row_locations['bzip']);
}
}
javascript function - this should create the array and send variables to text fields. Code: function updateAddress() {
var mail = $.parseJSON(<?php print json_encode(json_encode($mail)); ?>);
{
if (comp_id in mail) {
document.getElementById('mailto').value=mail.comp_id.mailto.value;
document.getElementById('madd').value=mail.comp_id.madd.value;
document.getElementById('madd2').value=mail.comp_id.madd2.value;
document.getElementById('mcity').value=mail.comp_id.mcity.value;
document.getElementById('mstate').value=mail.comp_id.mstate.value;
document.getElementById('mzip').value=mail.comp_id.mzip.value;
} else {
document.getElementById('mailto').value='';
document.getElementById('madd').value='';
document.getElementById('madd2').value='';
document.getElementById('mcity').value='';
document.getElementById('mstate').value='';
document.getElementById('mzip').value='';
}
}
}

Hi, In a nutshell,can anyone tell me how to copy a 2d (two dimensional ,2 dimensional) php array to 2d javascript array?I would be obliged if anyone can provide me a method of doing that OR I have written a code to copy a 2d php array to a 2d javascript array.It is working but there is one problem(please see the following).Can anyone tell me what I am doing wrong here? The 2d php array is $quest[100][6] and the 2d javascript array is questions[100][6] .

How come this code doesn't work? After searching this site I could not find any old posts on how to position the PROMPT box. As default (as you all most likely know) the prompt box in IE browser comes up in the top left corner. not very visable and would like to center it so it would be more visiable to the user being prompted. Can someone help me with this? thanks John I'm working on an html form that will be launched from within another application, but every time it launches the form none of the JS coding works because of the stupid IE security. If I launch the form from outside the application I just have to select "allow blocked content" from that stupid information bar that says "to help protect your security IE has restricted the webpage from running scripts...." I added the application site to our trusted sites and basically turned off security for that zone but it still doesn't work. Obviously there is a way to run JS without allowing the content, but I don't do enough coding to know how that is done. Can someone help me out please? I need the JS to run automatically without that information bar appearing at all. 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> Trying to get this prompt window to work so I can begin a calulation function--Am I even in the ballpark? var chargeAmount = window.prompt("Enter a charge amount", Enter charge amount here."); var discountPercent; var totalCharges; function confirmSubmit() { if (document.forms[0].name.value == "" || document.forms[0].name.value == "Enter your name") { window.alert("You must enter your name."); return false; } function confirmReset() { var resetForm = window.confirm("Are you sure you want to reset the form?"); if (resetForm == true) return true; return false; } } /* ]]> */ </script> </head> <body> <h2>Charge Information</h2> <form action="FormProcessor.html" method="get" enctype="application/x-www-form-urlencoded" onsubmit="return confirmSubmit();" onreset="return confirmReset();"> <p>Customer Name: <input type="text" name="name" value="Enter your name" /> </p> <p>Customer Type:</p> <input type="radio" name="rb" value="regular" />Regular<br /> <input type="radio" name="rb" value="silver" />Silver<br /> <input type="radio" name="rb" value="gold" />Gold<br /> <br /><br /> Total Charges:  <input type=text value="" name="total charges" size=10;> <br /><br /> Discount:  <input type=text value="" name="discount" size=10;> <br /><br /> Payment:  <input type=text value="" name="payment" size=10;> <input type="button" name="calc" value="Calculate Payment" onClick="return calcpay(this.form)"> <input type="reset" name="reset" value="Reset Form" > </form> </body> |
