var result = 0;
var items = '';
for(var i=0;i<nums.length;i++)
{
if(nums[i].checked)
{
result+=parseFloat(ntext[i].value);
items+=nitem[i].value+'\n';
}
}
f.answer.value=result;

if (nums[i].checked) {
window.alert("Your total is " + f.answer.value=result;);
}

Similar TutorialsHello- I wish to not have an alert box, but if I remove the alert the function after the alert doesn't fire. Not sure what the issue could be, so if any js gurus out there can lend any assists, it would be most appreciated. Thanks. Alex- Code: function showPrintView(view){
var win2;
win2 = window.open("trans?print=true","Window2","width=600,height=600,scrollbars=yes");
if(view=='1') {win2.alert('Preview'); win2.showView1(); }
if(view=='2') {win2.alert('Preview'); win2.showView2();}

Now I am using the following code to display the alert. But the alert is getting displayed even I click on any links. But the alert should not displayed when i click the link. If you have any solution, please let me know. Thanks in advance. This is my code: <HTML> <head> <script> function closeIt() { return ""; } window.onbeforeunload = closeIt; </script> </head> <body> <a href="http://www.test.com">Click here to navigate to www.test.com</a> </body> </html> Hi everyone. New programmer here trying to get fix this one specific issue I am having and I could use some help. Using Javascript, ASP.net with C# code behind. I am validating a textbox using the onblur event. It is being validated in that it must have an alphanumeric entry before the user tabs off of it to the next box. The validation part works, the part that doesn't work is that I get the validation alert textbox if I close the window. I have a workaround in that I am assigning that textbox a character using windo.onberforeunload but I know that isn't right. Here is what I have so far... Code behind on Page_Load... Code: txtCLBRTNWC.Attributes.Add("onblur", "return reqVLD(this)");
here is my textbox field... Code: <asp:TextBox ID="txtCLBRTNWC" runat="server" Width="75" MaxLength="4"
ontextchanged="txtCLBRTNWC_TextChanged" TabIndex="1"
onkeyup="clbwclngCHK(this);" ></asp:TextBox>
And here are the 2 functions being used... Code: function reqVLD(alphanumericChar)
{
var chk = /^[a-zA-Z0-9]+$/;
// var boxid = document.getElementById("<%=txtCLBRTNWC.ClientID%>").value;
// var matchArray = boxid.match(chk);
if(document.getElementById("<%=txtCLBRTNWC.ClientID%>").value.match(chk))
{
return true;
}
else
{
document.getElementById("<%=txtCLBRTNWC.ClientID%>").focus();
document.getElementById("<%=txtCLBRTNWC.ClientID%>").value = "";
alert("Please enter a Work Center.");
return false;
}
}
function clbwclngCHK(obj_in)//When txtCLBRTNWC entry hits the max of 4 auto focuses to next box.
{
if (obj_in.value.length == 4) document.getElementById("<%=txtSTRTDT.ClientID%>").focus();
}
Here is my work around... Code: window.onbeforeunload = function ()
{
document.getElementById("<%=txtCLBRTNWC.ClientID%>").value = "1";
}
Summary. User has to enter something in box before they can move on. This is checked and validating using an onblur event. Problem is, the onblur event fires if closing\exiting the window. I know there has to be a better way of doing this. Any advise or help would be greatly appreciated.

But I am so bad I cannot even get a window alert to pop up. All I want to do is call the function in the body. But do not know how... Working on a project and I am trying to get error messages to pop up when either a number wasn't entered or another error message if nothing was entered. otherwise if a number was probably entered it would perform the proper function, heres where I am at, does anyone know what is wrong with it? it wont calculate or even throw up a pop up box. Code: <script language="JavaScript" type="text/javascript">
function check_numbers(){
var sal = document.temp_form.num3.value;
var error_message = "";
if (sal == "")
{
error_message += "You must enter a value gross annual salary \n";
}
else if (isNaN(sal))
error_message += "Value entered is not a number, please try again. \n";
}
if (error_message != "")
{
alert ("Please correct the following errors: \n_________________________________\n\n" + error_message);
}
else{
Calculate( parseInt(sal))
}
}
function calculate()
{
var sal = Number(document.getElementById('num3').value);
var fName = document.getElementById('num1').value;
var lname = document.getElementById('num2').value;
alert('Hello '+ fName + ' '+ lname + ', you would pay $'+ sal * .2 + ' in Federal taxes and $'+ sal * .1 + ' in State taxes, leaving you $'+ sal * .7 + ' to take home annually!');
}
And then here is the HTML part of it. Code: <b> Here is a pay slip generator that will determine your net annual salary. <br> Simply type in your first and last name along with gross salary and hit calculate. <br> Doing this will let you know how much you will end up paying in both Federal and State taxes. </b> <form action="" method="post" name="temp_form"> <p> Enter your First Name: <input name="num1" type="text" id="num1" size="10" maxlength="10"> </p> <p> Enter your Last Name: <input name="num2" type="text" id="num2" size="10" maxlength="10"> </p> <p> Enter your gross salary: <input name="num3" type="text" id="num3" size="10" maxlength="10"> </p> Click this button to calulate your annual net pay! <input type="submit" onclick="check_numbers()" value="Generate Pay Slip" /> <input type="button" value="Reset Form" onClick="this.form.reset()" /> </FORM> </body> </html> 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 attempted several variations of this, none of which seem to help. I have narrowed this down to being the central problem at hand. Do i just have something out of place? Code:
if (monthly_pay>=1000)
{bank_account="Okay";}
else if ((monthly_pay>=700)&&(monthly_pay<=999))
{bank_account="Still Okay";}
else if ((monthly_pay>=500)&&(monthly_pay<=699))
{bank_account="Start to worry";}
else if ((monthly_pay>=300)&&(monthly_pay<=499))
{bank_account="Panic";}
else if (monthly_pay<=299)
{bank_account="Chapter 9";}
else
{document.write("Marry Up")}
}
Optionally, could I not do else if and somehow use this as a Nested If? Any help appreciated, Thank You 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.

Any thoughts? Thanks Hello, I have a bit of javascript that automatically loads Shadowbox on load. It works perfectly in Firefox, Chrome but NOT IE. If I put a standard link to open Shadowbox does work in IE, so it's not the shadowbox, it's definitely the window.onload bit which isn't working. Here is my code. Code: <link rel="stylesheet" type="text/css" href="shadowbox/shadowbox.css">
<script type="text/javascript" src="shadowbox/shadowbox.js"></script>
<!--this bit is for a link to open the Shadowbox from a link elsewhere on the page -->
<script type="text/javascript">
Shadowbox.init({players:['swf']});
</script>
<script type="text/javascript">
window.onload = function() {
Shadowbox.open({
content: 'flash/flash002.swf',
player: "swf",
title: 'Open Shadowbox',
width: 1200,
height: 800,
});
};
</script>
This DOES work though, so I know it's not the Shadowbox with the issue Code: <a href="flash/flash002.swf" rel="shadowbox;height=800px;width=1200px">Open Shadowbox</a> Really appreciate your help! Nicola Hi guys, I have read that the window.close won't work unless the window was opened through window.open. Eventhough I have the window opening through window.open method the window.close simply wont close the window. Below is my code. I appreciate you help as I am desperate to finish my project and this is the only thing between me and the closed project. I have this in the <head> in the parent window. Code: <script language="javascript">
function MM_openBrWindow(theURL,winName,features){
var left = (screen.width/2)-(800/2);
var top = (screen.height/2)-(560/2);
features = features + ",left=" + left;
window.open(theURL,winName,features);
}
</script>
the left and top is to center the window which is working. Then I have the below code in my button which is to open the window. Code: <input type="button" value="E-MAIL" onClick="MM_openBrWindow('email.php?camp_id=<?php echo $encrypted; ?>','','width=860,height=600'); return false"/>
The $encrypted is created beforehand and the window gets opened as well. Now in the popup window... Up on submitting a form, I need the popup to close after saying 'email has been sent'. this is the code for calling the fuction Code: echo "<script language='javascript'>success();</script>"; I get the alert too. Code: function success(){
alert('E-Mail Sent Successfully');
window.close();
}
I even get the alert mentioning "E-Mail Sent Successfully". But simply the window is not closed. Can you guys please shed me some light on this.... Your help is greatly appreciated Ohh and by the way I'm running FF8. Cheers E Hi There, The following piece of code is working fine in IE6 but not in IE 8: if (Windowvar != null) { Windowvar.close(); } Windowvar= window.open(sUrl, 'static', viewerWinOption, true); To explain the functionality: 1. User clicks on one of the links on page 1 2. Clicking takes user from Page 1 to Page 2 (the transaction page). 3. Along with page 2, another page (Page 3) is opened. 4. User saves the transactions in the Page 2 and he is taken back to page 1 5. User clicks other link in Page 1 and activity in point 2 is repeated along with point 3 The issue is, when User clicks on the link AGAIN(for second transaction) in the Page 1 the Page 3 opens in the same browser window in the IE 6 but in IE 8 it opens in the differenct browser window (which shouldnt be happening) Any help will be appreciated. Regards, Sameer. Hi Guys, I have written a simple code to open up a new window onclick of a button as follows; Code: function loadExamp()
{
var reqType = getElementValue("reqType", 1);
window.open("../jsp/loadExamples.jsp?reqType=" + reqType, "Connection Test Utility - Message Examples", "width=500,height=300,menubar=no,status=yes, location=yes,toolbar=no,scrollbars=yes" );
return;
}
The problem is that this code is working on Google Chrome but not in Firefox and IE. Why is that and how can I resolve this issue. I am using Firefox 3.6.11 and IE 8.0.XX. Also I tried to open a new window using <a href> option with the same URL and its working but the only problem is that I want to pass my next JSP an argument which is only possible with function or script. I googled it but couldn't find much information except that there is some security problem. For that I have disabled the 'Pop up Bloker' on both Firefox and IE but still not working. When I click my button there is no activity with 'Firefox' but IE gives me error as follows; Code: Message: Invalid argument. Line: 74 Char: 2 Code: 0 URI: http://localhost:8080/T24Utility/scripts/verifyCxPool.js Please help, Thanks, -- Sjunejo Can someone please help with this code. The window is supposed to automatically scroll and move but it isn't working. (It was taken from a discontinued book called javascript in 24hrs) The javascript: Quote: var pos=100; function Scroll(){ if (!document.getElementById ) return; obj=document.getElementById("thetext"); pos -=1; if(pos < 0-obj.offsetHeight + 130) return; obj.style.top=pos; window.setTimeout("Scroll();", 30); } //start scrolling when the page loads window.onload=Scroll; the css: Quote: #thewindow{ position:relative; width:180px; height:150px; overflow:hidden; border:2px solid red; } #thetext{ position:absolute; width:170px; left:5px; top:100px; } the html: Quote: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <link rel="stylesheet" type="text/css" href="scroll.css" /> </head> <body> <h1> scrolling window example</h1> <p>This example shows a scrolling window created using javascript and the w3cdom.The red border window is actually a layer that shows a cliped portion of a larger layer"</p> <div id="thewindow"> <div id="thetext"> <p>This is the first paragraph of the scrolling message.The message is created with regular html</p> <p>Entries within the scrolling area can use any html tags.They can contain <a href="#">links</a></p> <p> No limit to the number of paragraphs that you can include here...</p> <ul> <li>For example you could format items using a bulleted list.</li> </ul> <p>The scrolling ends when the last part of tht scrolling text ids on the screen.You've reached the end.</p> </div> </div> </body> </html> Hi, well i used soh tanaka inline modal window which is a popup window like lightbox.
