JavaScript - Checking For Spaces In Javascript
Hey Guys,
I am a student doing my Cert IV in IT and am having a bit of trouble with some code. I have a form that when a letter is entered it returns a message saying you need to enter numbers in, and am trying to find a way of it checking if there are spaces in the numbers entered at the same time as checking if a number has been entered. My code looks as follows: Code:
<html>
<head>
<title>Activity 2.25</title>
</head>
<script type="text/javascript">
function validateform()
{
var element;
var BikeMoney;
var TVMoney;
var iPodMoney;
var CarPrice;
var flag;
flag="OK"
element=document.getElementsByTagName('input');
for(counter=0; counter<element.length; counter++)
{
switch (element[counter].type)
{
case "submit":
break;
default:
if(isNaN(element[counter].value))
{
alert("You will need to enter a number into " + element[counter].name);
flag="NotOK"
}
else
{
BikeMoney=element[0].value;
TVMoney=element[1].value;
iPodMoney=element[2].value;
CarPrice=element[3].value;
}
}
}
if(flag=="OK")
if ((Number(BikeMoney)) && (Number(TVMoney)) && (Number(iPodMoney)) && (Number(CarPrice)))
{
TotalMoney = parseFloat (BikeMoney) + parseFloat (TVMoney) + parseFloat (iPodMoney)
if(TotalMoney >= CarPrice)
{
alert("The total money is " + TotalMoney + " and the car price is " + CarPrice + " and you can afford the car");
}
else
{
alert("The total money is " + TotalMoney + " and the car price is " + CarPrice + " and you cannot afford the car");
}
}
else
{
alert("Enter numbers Please");
}
}
</script>
<body>
<form name="input form" method="post" action="">
<table>
<tr><td>Enter money from bike sale</td><td><input type="text" name="Bike Money"></td></tr>
<tr><td>Enter money from TV sale</td><td><input type="text" name="TV Money"></td></tr>
<tr><td>Enter money from iPod sale</td><td><input type="text" name="iPod Money"></td></tr>

<tr><td></td><td><input type="submit" value="Submit Details" onclick=validateform()></td></tr>
</table>
</form>

Similar TutorialsHi. I'm having some trouble with validating all my fields in my form. I'm posting my code here. Code: function validateForm()

alert("Student name must be filled out");
return false;

I need to alert the user with a messagebox for six fields if ever they're not filled in. How do I achieve that? Hi all. This is a generic question as Google didn't help at all, does anyone know how to check if javascript is enabled and then I want to display info based on that. I don't mind how I do it, HTML, PHP or whatever Regards, Magnetica Hai Forum, May be this question is not in correct format, I want to know about how to check a particular file is exists or not ? using Javascript.One thing without using ActiveXObject because it is supports in IE only. Thanking You, Santosh Srinivas.G I have a javascript that should convert any date into a number between 1 and 260. Based on the outcome of that calculation, a viewer is directed to a specific web page. How can I verify the calculation? How can I see what number javascript is arriving at so I can backtrack to the error? It is not serving up the correct page. I have compared the results to a calculator on another website that uses a different script to calculate the same result -- that's why I am saying the end results are not correct. On the other website, scroll down to where you enter a date. It returns a name just above the date (example: July 25, 1970 returns Electric Star). The script I included above returns Yellow Sun. July 25, 1970 should = 68. Code: function calculate() {
if(!isValidDate())
return;
var result = 0;
var cuttingAge = 260;
var yearBox = document.getElementById("year");
var year = yearBox.value;
var month = document.getElementById("month").value;
var day = document.getElementById("day").value;
//Rule # 1
if(month==1 || month==2){
var selectedYearIndex;
for(var i=0; i<yearBox.options.length; i++){
if(yearBox.options[i].selected){
selectedYearIndex = i;
break;
}
}
year = yearBox.options[selectedYearIndex-1].value;
}
//Rule # 2

Hello, Can you someone point me to the right script? I have a text box and would like to see if the value of the input matches the values defined in a JavaScript array. For example, the JavaScript array will hold five values: v1 = Tom v2 = Jerry v3 = Michael v4 = Stephanie v5 = Michelle If the text box does not equal one of those values, an alert will pop up stating it does not match. Thanks. Hi, I'm wondering if someone can help me. I have recently used this tutorial: http://net.tutsplus.com/tutorials/ph...-confirmation/ to develop a more complex sign up form for a competition for a client. Basically, the way the validation has been done is different to many other validation methods I've used before and don't understand how to implement it, for some additional requirements. This is an example of the PHP validation code that I have altered, to suit my form requirements: Code: //quick/simple validation
if(empty($code)){ $action['result'] = 'error'; array_push($text,'You forgot to enter your entry code'); }
if(empty($name)){ $action['result'] = 'error'; array_push($text,'You forgot to enter your name'); }
if(empty($email)){ $action['result'] = 'error'; array_push($text,'You forgot to enter your email address'); }
This code only validates that there is content in those fields. But, for example on the 'entry code' field, I would like to put a maximum character input there and restrict certain characters, as well as a standard 'email' validation, so that the form is sent through to the database correctly. If anyone knows how I can do this, with this sign-up form in particular, please assist me, as every other method I've tried to work with this form hasn't worked and caused the form to error. Thank you in advance. So <br/> creates a brake but is there a way to make "tab" space?
I have a string variable: var mystring = ' hello world '; How can I truncate white spaces placed before or after my string value? Thank you in advance to help. How can I to delete white spaces around parameter that I to pass with HTML forms. For example, if I have 'firstname lastname ' or ' firstname lastname', exist it a builtin function in javascript to obtian 'firstname lastname'? savio Hi All, I have a form in my homepage which takes some values. In that, a text box takes multiple values seperated by spaces. I have allowed only alphanumeric characters in that with the following code. Code:
function rmsplcharchkdepo()
{
var iChars = "\\\/~!@#$%^&*()=+[]{}|;:?,.\"`'<>";
var un= document.getElementById("deposit").value;
for (var i = 0; i < document.ipmform.deposit.value.length; i++) {
if (iChars.indexOf(document.ipmform.deposit.value.charAt(i)) != -1) {
alert ("Error!! Remove Special Characters.");
document.getElementById("deposit").value = un.substring(0,0);
return false;
}
}
}
How can i trim the multiple spaces entered by the user between values instead of one single space allowed.. For eg: TEXTBOX:INDIA USA UK User should not be able to enter a space at the beginning, multiple spaces between the values and at the end. This is just to avoid unwanted complications at the backend. In brief i need a script which trim multiple and consecutive spaces to one. It would be a great help if some one can help me in this. Hi guys (and gals) Working on my uni essay, and really struggling here with a resolution to this part of code. Maybe I shouldnt be looking for the answer, but more so on where I am going wrong. What I am meant to do is replace the spaces in sString with the actual word 'space' i.e hello 'everyone' = 'hellospaceeveryone' Any help would be appreciated! Code: function substituteSpaces(aString)
{
sRet = '';
for (var iA = 0; iA < aString.length; iA++)
{
if (iA = 0)
sRet = sRet + ' ';
//sRet = sRet + 'space';
//var nextLetter = aString.charAt(iA);
// sRet = sRet + nextLetter;
}
}
sSpace = substituteSpaces('a string with spaces');
alert ("Hello");

Please help if you can, I am desperate and my website looks crazy right now! THANKS!!! hi all i m using the following validation code to validate email id Code: if (!/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,4})+$/.test(document.getElementById("customer_name").value))
{
msg=msg+"Must Enter a valid Login-id/Email\n";
document.getElementById("customer_name").focus();
}
now i need that if the email id contains white blank space in front of email id or end of email id then this validation should pass otherwise not. at present if there is blank space in front and end of email id then the validation doesnt passes and gives alert. what should i add in it to validate it or how can it automatically remove white spaces before validating. vineet Hi everyone, I run a math site and I just recently built a little program to generate math problems. When the user submits the correct answer the program changes the problem and all the steps/hints. Everything works fine except that during the change over there are all these weird blocks (same color as my background) (*FireFox Only). It only lasts for a couple of seconds, but it would be nicer if it smoothly replaced the problem. Here is the test site: http://www.rootmath.org/test/solving-limits The program/practice problem is at the bottom, if you don't know how to solve it you can hit "hint" until it gives you the answer. When you enter the correct answer and then click for a new problem you'll see the funky blocks. Any help/suggestions would be greatly appreciated! Here is the code: writeProblem() is called when the user gets the right answer and asks for another problem: Code: var writeProblem = function(){
//these are neccessary after the first call to writeProblem.
$(".steps").hide();
$("#submit_answer").show();
$("#next_problem").hide();
showStep.reset();
//CLEAR "steps_area"
var problem_area = document.getElementById('steps_area');
while(problem_area.firstChild){
problem_area.removeChild(problem_area.firstChild);
}
//Create a limit problem
var limit = limits();
limit.setDenominator(rand(6,0));
var denom = limit.getDenominator();
var randInt = 0//rand(3,0);
var lim = limit.getType(randInt, denom);
var step = lim.step(denom);
answer = lim.getAnswer(); //made global so checkAnswer() can access it
var x = document.getElementById('problem');
x.innerHTML = addLatex(lim.problem);
var problem_area = document.getElementById('steps_area');
//loop over array of steps and print them to steps div
var length = step.length;
for(var i=0; i<length; i++){
var divTag = document.createElement("div");
divTag.id = "step" + i;
divTag.className = "steps";
divTag.innerHTML = step[i];
problem_area.appendChild(divTag);
MathJax.Hub.Queue(["Typeset",MathJax.Hub,'step' + i]);
}
// MathJax Queue for processing latex that javascript filled in
MathJax.Hub.Queue(["Typeset",MathJax.Hub,'problem']);

Hi I am trying to make all the cells within a table droppable spaces, using the scriptaculous library. However I am not able to do so, and I am not certain why. The table cells are creating within the javascript. I then try to apply the droppables to the table cells through iteration, through the function when the document loads. It does not seem to be working. The document accesses an external php page and has inline php within a div element. I am uncertain if by having the draggable elements instantiated within the php script, that this would be causing any problem, as I cannot see how this would be, the php draggables all appear to be corresponding to the css in the document. Any help with the droppables would be appreciated. I have set up a css class hover, so that when the draggable passes over the droppable the edges of the droppable area should be turning blue, but this is not happening. Not sure what the problem is.

hello, This seems very basic, but I am running into a complication. What I would like to do is check if a certain div is displayed or hidden (really doesnt matter which) then set a map zoom level based upon that. here is my current function. function closeDirections(){ gdir.clear(); if(document.getElementById("river").style.display="none"){ map.setZoom(16); hideID('river'); showID('main'); } if(document.getElementById("main").style.display="none"){ map.setZoom(12); hideID('main'); showID('river'); } } Also here is a link to my map, just in case. map I have tried several variations, but from what I can tell with every instance, it only examines the first and never considers the second "if". I thought to rememdy this issue by using if/else...same issue. The only thing I could think is a nested if statements, but I am not sure what to use as a parent if. I have searched for a while, but cannot seem to find something like an .is_hidden(). Something that I could see if its true/false. Any help would be very much appreciated. I keep getting myself into trouble because I tend to use my Java reference when coding Javascript, and of course Javascript doesn't support all Java functions. I've just discovered that apparently Javascript doesn't support the trim() function. But curiously, if I code it as: mystring.trim() then Firefox will handle it without any errors. (I haven't actually checked to see if whitespace is removed from around the string.) But when I code it like this: trim(mystring) then firefox gives an error. I've also found a couple of situations where I've made syntax errors, and Firefox gives no error message. This makes debugging tricky, since the only resource I have available is Firefox's Error Console. Safari has no error reporting whatsoever, AFAIK. MSIE seems to find some errors that Firefox misses, but I don't have MSIE on my main computer, so it's a nuisance to use. As a hobbyist, I have no budget to buy Javascript development tools. Is there something free available that does a better job of finding errors? I need to check to see if a cookie has been previously created: Code: var startnum = readCookie('a1');
if (document.cookie.indexOf('a1') == -1){
var startnum = "0";
}
Should line 2 be: Code: if (document.cookie.indexOf('a1') == null){
? Does == -1 do the same thing? I made a cool calendar application I want someone to look over it and see if I messed up anywhere cause I have a good feeling I did. It was designed to be an active desktop ^.^ that way I get my desktop image and a calendar ^.^ index.html Code: <html> <head> <title>Desktop</title> <link rel="stylesheet" type="text/css" href="css/mainTemplate.css" /> </head> <body> <img id="bgImage" src="images/nerbian-entrance.jpg" alt="Active Desktop made by Shelby Brittain" /> <table id="mainTable"> <caption id="caption"> </caption> <tr> <th> Sunday </th> <th> Monday </th> <th> Tuesday </th> <th> Wednesday </th> <th> Thursday </th> <th> Friday </th> <th> Saturday </th> </tr> <tr> <td id="d1"> </td> <td id="d2"> </td> <td id="d3"> </td> <td id="d4"> </td> <td id="d5"> </td> <td id="d6"> </td> <td id="d7"> </td> </tr> <tr> <td id="d8"> </td> <td id="d9"> </td> <td id="d10"> </td> <td id="d11"> </td> <td id="d12"> </td> <td id="d13"> </td> <td id="d14"> </td> </tr> <tr> <td id="d15"> </td> <td id="d16"> </td> <td id="d17"> </td> <td id="d18"> </td> <td id="d19"> </td> <td id="d20"> </td> <td id="d21"> </td> </tr> <tr> <td id="d22"> </td> <td id="d23"> </td> <td id="d24"> </td> <td id="d25"> </td> <td id="d26"> </td> <td id="d27"> </td> <td id="d28"> </td> </tr> <tr> <td id="d29"> </td> <td id="d30"> </td> <td id="d31"> </td> <td id="d32"> </td> <td id="d33"> </td> <td id="d34"> </td> <td id="d35"> </td> </tr> <tr> <td id="d36"> </td> <td id="d37"> </td> <td id="d38"> </td> <td id="d39"> </td> <td id="d40"> </td> <td id="d41"> </td> <td id="d42"> </td> </tr> </table> </div> <script type="text/javascript" src="js/mainLib.js"> //<![CDATA[ //]]> </script> </body> </html> css/mainTemplate.css Code: body {

Thanks Shelby Hi, I know this is painfully obvious, but I can't get my head around it. Basically, these loops: Code: for (var p=0; p < routeInfo.length; p++) {
times = routeInfo[p].getElementsByTagName("time");
dirs = routeInfo[p].getElementsByTagName("dirs");
dist = routeInfo[p].getElementsByTagName("dist");
for (q=0;q<dirs.length;q++) {
count++;
time = GXml.value(routeInfo[p].getElementsByTagName("time")[q]);
dir = GXml.value(routeInfo[p].getElementsByTagName("dirs")[q]);
dist = GXml.value(routeInfo[p].getElementsByTagName("dist")[q]);
if (time.length>1) {
way+='<div class="dir">'+count+'. '+dir+'</div>'+'<div class="results"><div class="time">'+time+'</div><div class="dist">'+dist+'</div><br><br>';
}
else way+='<div class="dir">'+count+'. '+dir+'</div><br>';
}
}
outputs lines of text, with two <br> between them. What I want is for if it's the last loop for that only to be one <br> so I'm thinking something like this: Code: if (last loop) {end =<br>}
else end=<br><br>
...
way+='<div class="dir">'+count+'. '+dir+'</div>'+'<div class="results"><div class="time">'+time+'</div><div class="dist">'+dist+'</div>'+end;
but I can't figure out what that "last loop" code should be. Any ideas? |
