Similar TutorialsGood Day, I am very new to JavaScript and I am working on an assignment that is almost finished, but I have a problem getting the result to work. When I enter the two values and then hit submit, nothing is returned. I am guessing that either my code is incorrect or I have used the wrong ids maybe. Basically, the user enters 2 parameters (hourly wage and hours worked) and the first function turns the parameters into the gross pay (depends on if the hours are standard pay or if overtime is involved). The second function takes the gross pay and does the tax amounts for local, state and federal. Then it adds all taxes to give a total of tax amount paid. The input for the parameters is done by <input> tag. The return reslut is supposed to be just the number which is the total amount of taxes to be taken out. This all has to be done by <input> tags. Could someone look over the html and JS and help me find where the problem is at. The instructor said we could use ? : operator for determining the pay rates, but I found it easier to do if/else staements because I was not sure how you would script that. Any help would be great.

I'm coding a simple random sentence generator & this is the beginning part of what I'm trying to accomplish. I created 3 different functions with 3 separate buttons & 3 separate text areas to display the noun, verb, or article once the button is pressed. However, when I press a button, nothing shows up in the text area! Can someone please tell me what I'm doing wrong & give me a fix? It has to be a simple problem, but I am very very new to this & need help. Thanks in advance! Code:

I will tell you now that I am not a javascript programmer and this is a very basic question. Please don't flame. I have been writing a web site and have found 2 functions that work and do what I want them to do, but I want to combine them. The first function will grab the window size.(it actually prints it out to the screen and I know how to get that to stop by taking out the last 2 lines) What I want to do with the results from the function alertSize() is exactly what the function res() does though. I want it to take the window size and jump to the appropriate web directory. What I don't know is if I can write that all as one function or if I have to pass the results of function alertSize() to function res(). Or how to do it for that matter, I don't even know what this is called in programming lingo. I am not asking for an answer here I would just like someone to point me in the right direction that I may learn a little more about what it is I want to do so I can get this to work. Giving me a search term would be a BIG help. Here is the first function. Code: // <script language="JavaScript"> //-->
function alertSize() {
var myWidth = 0, myHeight = 0;
if( typeof( window.innerWidth ) == 'number' ) {
//Non-IE
myWidth = window.innerWidth;
myHeight = window.innerHeight;
} else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
//IE 6+ in 'standards compliant mode'
myWidth = document.documentElement.clientWidth;
myHeight = document.documentElement.clientHeight;
} else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
//IE 4 compatible
myWidth = document.body.clientWidth;
myHeight = document.body.clientHeight;
}
window.alert( 'width = ' + myWidth );
window.alert( 'height = ' + myHeight );
}
// </script> //-->
and the second function. Code: // <script language="JavaScript"> //-->
function res()
{
alert('Screen Resolution Is '+screen.width+' by '+screen.height);
}
if ((screen.width>=1280) && (screen.height>=1024))
{
window.location="/12/index.html";
}
else if ((screen.width>=1024) && (screen.height>=768))
{
window.location="/10/index.html";
}
else if ((screen.width>=800) && (screen.height>=600))
{
window.location="lowres1.html";
}
else if ((screen.width>=640) && (screen.height>=480))
{
window.location="lowres2.html";
}
else
{
window.location="lowres3.html";
}
// </script> //-->
Hello all, I am new to these forms, and new to Javascript as well. I have gone through some lessons, and have been trying to write a simple script on my own. Here is what I am trying to do: I am calculating a volume, and want to display the result of that calculation. I then want to take the result and multiply it by 2 and display that as well. Here is what I have so far: Code: function volume (l, w, h) {
return l * w * h;
}
console.log("Volume = " + volume (2, 2, 2));
So far so good... but I cant figure out how to then take that result that was displayed in the console and save it as a variable (if that would be the correct way to do it) so that I can modify the result by 2. I have tried several things with no luck. How can I save the result of a function or pass it to another function? Thanks in advance! Hello!

First post - spent the whole afternoon trying to figure it out and have hit a wall. I'm trying to check a database of lotto numbers against 3 different values and have gotten it that to work. What I need is to give a feedback message if no match is found once the submit button is clicked. Code: function winCheck() {
var grandPrize = $('#grandPrize').val();
var otherPrize = $('#otherPrize').val();
var addPrize = $('#addPrize').val();
var resultrange = $('#resultrange').val();
db.transaction(
function(transaction) {
transaction.executeSql(
'SELECT * FROM entries WHERE daterange = ? ORDER BY lottonum;',
[resultrange],
function lottoCompare(transaction, result){
for (var i=0; i < result.rows.length; i++) {
var row = result.rows.item(i);
rowData = [row.lottonum];
rowStr = rowData.toString();
//the if else statements should go here.
if (rowStr == grandPrize){
alert('The lotto number ' + grandPrize + ' is a jackpot winner');
}
if (rowStr.slice(-7) == otherPrize.slice(-7)){
alert('The lotto number ' + rowStr + ' is a winner of $40,000');
}
if (rowStr.slice(-6) == otherPrize.slice(-6)){
alert('The lotto number ' + rowStr + ' is a winner of $10,000');
}
if (rowStr.slice(-5) == otherPrize.slice(-5)){
alert('The lotto number ' + rowStr + ' is a winner of $4,000');
}
if (rowStr.slice(-4) == otherPrize.slice(-4)){
alert('The lotto number ' + rowStr + ' is a winner of $1,000');
}
if (rowStr.slice(-3) == otherPrize.slice(-3)){
alert('The lotto number ' + rowStr + ' is a winner of $200');
}
if (rowStr.slice(-3) == addPrize){

return false;

Any help is appreciated Hi, My webpage can work normally in IE but not in Safari(e.g. when I clicked on some buttons like 'Delete' button, the page opened in Safari stays the same while it should delete the object chosen). When I tried debugging on Safari, after clicking the 'update' button, this message error appeared: "TypeError: Result of expression 'this.form.fireEvent' [undefined] is not a function". I believe this code makes the incompatability between the 2 browser: Code: function DeleteClick()
{
var frmSWO = document.getElementById("form");
var answer = confirm("Do you really want to delete?")
if (answer != 0)
{
frmSWO.action = "/domsWeb/mtd/doms/web/operation/eDepotMNR/controller/manageWorkOrder/DeleteJobOrImage.do";
frmSWO.method = "post";
this.form.fireEvent('onsubmit');
frmSWO.submit();
}
}
Any suggest how should I amend the script for it to work on 2 browser concurrently? Thanks all! Hi, I tried displaying few images as MENU using Javascript. These images are showed normally in Firefox and chrome except Internet Explorer. Help plz
Hello everyone! Hi, I am a complete beginner at Javascript(started a few days ago) and was having trouble with some functions. I'm trying to get the inputs required to change based on an option selected in a drop down menu. I was intending to run different scripts based on whatever is chosen but when I ran a test using an alert function, I realized my code isn't working. I went online and found really confusing stuff like "running a for loop through an array to make a dynamic select feature". Still confused any help would be appreciated. My code thus far: Code: <html>
<head>
<title>Practice</title>
<script language="javascript">
function myScript()
{
var loanType = document.form1.loan.options.text
if (loanType == "Bank A")
{
alert("Working")
}
}
</script>
</head>
<body>
<form name="form1">
<select id="loan" name="loan" onchange="myScript">
<option></option>
<option>Bank A</option>

Maybe not the best way, but it does the trick. Reply With Quote 01-08-2015, 11:43 AM #3 Philip M View Profile View Forum Posts Supreme Master coder! Join Date Jun 2002 Location London, England Posts 18,371 Thanks 204 Thanked 2,573 Times in 2,551 Posts You have quite a lot of obsolete code:- 1) It is obsolete to assign a name to a form and permitted only for the sake of backwards compatibility. 2) <script language=javascript> is long deprecated and obsolete. Use <script type = "text/javascript"> instead (in fact also deprecated but still necessary for IE<9). 3) Scripts should normally be placed right in front of the </body> tag. Any script can optionally go in the head if you wrap it inside a load event listener so that it can't run before the page loads. 4) Use the value of a select box option, not the text. 5) It is recommended that you place the opening brace following the function, if, else, for, while, do, switch, and try statements on the same line and not on the following line. Apart from that every Javascript statement should be followed by a semi-colon (;). It is quite possible to disregard this advice, but if you do one day it will rise up and bite you in the undercarriage. Code: <html>

I read through some of the rules, but it is late and I am in a hurry. Any help would be greatly appreciated. I need the image file names in my array to be shown in the text box. I am not quite sure how to do this. I have been trying for some time but cannot figure it out.

I have some javascript I need to execute that is located in an SSI footer. The purpose of the code is to find out what domain the page was loaded at and then to tailor some links to match. Because of how the hosting environment is set up (which I have no control over) when the links don't match the domain they aren't included. I also have to use a complete url (as opposed to relative url) because the footer is included in many different web pages. The problem is that the code is executed but it also is displayed as plain text in firefox. The test site is http://test.ci.edina.mn.us Help! The code is: Code: <script type="text/javascript"> var domainName, strOut; domainName = document.domain; strOut = '<link rel="stylesheet" type="text/css" href="http://' + domainName + '/js/jquery.fancybox/jquery.fancybox.css" media="screen" />'; document.write(strOut); strOut = '<script src="http://' + domainName + '/js/jquery-1.3.2.min.js" type="text/javascript"></script>'; document.write(strOut); strOut = '<script src="http://' + domainName + '/js/jquery.fancybox/jquery.fancybox-1.2.1.js" type="text/javascript"></script>'; document.write(strOut); strOut = '<script src="http://' + domainName + '/js/jquery.easing.1.3.js" type="text/javascript"></script>'; document.write(strOut); </script> I have an iFrame that is loaded when a user types a url into a text box. Is it possible to display the meta-description of the page that is diplayed in the iFrame in the main (parent) page ? Here is the Iframe code I am using in the body: Code: <iframe src="http://www.mhgoebel.com" frameborder="0" id="frame" width="320" height="356" scrolling="no"> </iframe> and here is the script in the header: Code: <script>
function goTo() {
var input = get("box").value,
frame = get("frame");
if(input.match(/\bhttp(.)*/)) {
frame.src = input;
} else {
input = "http://" + input;
frame.src = input;
}
}
function get(id) {
return document.getElementById(id);
}
</script>
Working on an Adobe form (non web) The "Award" field is a bit troublesome. Award is not required every time therefore I left that out of it's field properties. I have also set the maxium amount of characters to 5. At times, it will be required therefore I want to set up validation that will return an error message if 1-3 characters are filled in but won't give any error message if 4 or 5 characters are entered in the field. I.e 0= Do nothing 1= Error 2= Error 3= Error 4= Do nothing 5= Do nothing Code: if ((event.value.length > 1) && (event.value.length < 4)) //trigger alert if 1-3 characters are entered
{
app.alert("The minimum amount of characters is 4");
event.rc = false;
}
else
{
// do nothing if 0,4 or 5 characters are entered
}
Hi, I'm trying to code a script that will display an approximate postage price based on different combinations of variables, but the numbers I defined for each case aren't reflected in the text box. I'm using a switch statement for all the different combinations of options, which the user will choose by selecting check-boxes. I'd really appreciate if anyone could point out where I'm going wrong. (Additionally, I know that this code probably isn't a very efficient way of doing what I'm doing - I'm open to suggestions on how to improve it.) I've attached all the relevant parts of the code, including how I defined variables originally. Many thanks in advance, Gil Code:

Thanks again. Is it possible to scrape displayed text you can't find in html source code ? The text shows up only when you click a link, but is still not visible in source code. That link has got a userid and is used as a variable in function ShowUserPhone(userid). If someone knows how to solve this mystery, please help. I added http://www.mediafire.com/file/9eo72u...wUserPhone.txt file as available .js source linked to that smart page. I've also put some comments there about URL original location. Here is the main function where the process started I guess: Code: function ShowUserPhone(userid){
var UserPhoneLink=document.getElementById("UserPhoneLink");
var UserPhone = document.getElementById("UserPhone");
if(document.images){
(new Image()).src="/pp-owners-list-click-counter.asp?UserId="+escape(userid)+"&counterType=detailsphone";
}
if (UserPhoneLink){
UserPhoneLink.style.display="none";
}
if (UserPhone){
UserPhone.style.display="block";
}
}
Please help. |
