JavaScript - Compiler Issue With Else And If
I am a student. I have eliminated all errors except this one.
Quote: Reservations.java:108: 'else' without 'if' else ^ 1 error Tool completed with exit code 1 I have both if and else there. I have gone through the code looking for another problem, but there are none. I am in a time crunch with this chapter ending tomorrow night. If you could point me in the right direction it would be fantastic. Because I am in a bind, and do not know where else to look. here is the area that the compiler is referring to. PHP Code: public void actionPerformed(ActionEvent e) { if (hidden.getState()); { JOptionPane.showMessageDialog(null,"You must select Nonsmoking or Smoking.","Error",JOptionPane.ERROR_MESSAGE); } else { int available = room.bookRoom(Smoking.getState()); if (available > 0) //room is available { roomDisplay[available].setBackground(lightRed);//diplay room as occupied roomDisplay[available].setText( roomDisplay[available].getText() + "\n" + nameField.getText() + " " + phoneField.getText() + "\nparty of " + numberOfGuests.getSelectedItem() );//display info in room clearFields(); } else //rooms is not available { if (Smoking.getState()) JOptionPane.showMessageDialog(null,"Smoking is Full","Error",JOptionPane.INFORMATION_MESSAGE); else JOptionPane.shoeMessageDialog(null,"Nonsmoking is Full","Error",JOptionPane.INFORMATION_MESSAGE); hidden.setState(true); }//end of else block that checks the available room number }//end of else block that checks the state of the hidden option button }//end of the actionperformed() method Here is the full code PHP Code: import javax.swing.JOptionPane;

Freaking IE. Must die. Really it must. Unfortunately, I have to code for it, and I can't figure out what went wrong he http://wyqued-design.com/dev/skyview/index.html The navigation, and layout, breaks in IE 7. Any ideas? -Emilie I have the following sample html file (attached). I am trying to display the calculated field using javascript and I created a function (I am a newbie) to do so. However, it persistently shows NaN instead of the required number. I have tried my best over a coupla hours racking my brains and the internet as to why it shows as not a number. I will appreciate any help. Thanks, So I have a search function that searches through an XML file depending on which criteria the user wants to search. It works great so far in Firefox, OK in IE and not at all in Chrome. There's only one problem I have with IE which is you have to click submit, you cant hit the enter key to search. Is this fixable? Ive tried writing a function where if it detects the enter key press, it "clicks" submit, but that didn't work. In chrome, I search for something but it says there's nothing to be found. My code is below and any help or a point in the right direction would be greatly appreciated. Code: <script type="text/javascript">

How would I edit it so that I can return the item? hi, i have a problem with innerHTML if i wrote document.getElementById('someid').innerHTML = "ok"; then it wroks but when i wrote document.getElementById('someid').innerHTML = "<sometext> ok"; it does not work. i.e. <sometext> is not visible if check on firebug / dom it display.. <sometext> ok </sometext> please help.. how do i print / display above string as it as. you may download file or check below link.. please click here Hi Experimenting.

LT Alright,ill go straight to the problem. I want to get all the elements with a certain tag.However i can only get the first one. my code: Code: function getTags(tag) {

var y = x.length;
for(var i = 0; i <= y;i++) {
return x[i];
}
}
Hello, The code below assigns a value to the Latitude and to the Longitude table cells when the submit button is pressed. I would like to have these values appear in text boxes instead. Obviously I need to amend onclick="javascript:usePointFromPostcode(document.getElementById('postcode').value, placeMarkerAtPoint)" to make this work but I can't seem to. Assuming two text boxes with names lng and lat, how would I amend the line? Thanks Code: <p align="left">
<table bgcolor="#FFFFCC" width="300">
<tr>
<td width="100">
<b>Latitude</b></td>
<td id="lat">
</td>
</tr>
<tr>
<td width="100">
<b>Longitude</b></td>
<td id="lng">
</td>
</tr>
</table>

I am having an issue with a variable I am getting from a javascript function. Randomly it will appear to find the height of the image I told it to find to be 0, which to me doesn't make sense. The code is meant to pull the size of the main image, then set navigation arrows to either side at the right height. The Function is first with the call of the function later. I left out the url, but otherwise, this is the only code that would be used. Any Help is greatly appreciated... This is the function located in the header: Code: <script type="text/javascript">
function arrowHeight(a){
var img = new Image();
img.src = a;
var divh = img.height;
var calc = (divh/2)-25;
return calc;
}
</script>
This is the code called later in the code: Code: <script language="javascript">
var a = arrowHeight(".../img0001.jpg");
document.write ("<a href='.../img0010.php'><img src='.../left.png' style = 'position: relative; right: 20px; bottom: " + a + "px;'/></a>");
document.write ("<img src=.../img0001.jpg' />");
document.write ("<a href='.../img0002.php'><img src='.../right.png' style = 'position: relative; left: 20px; bottom: " + a + "px;'/></a>");

Hello I have some JS email validation which does not appear to be working. I originally had a form and decided to add validation to it, so I am adding JS to that original file. My original form used this: Code: <form action="form_script.asp" method="POST" enctype="multipart/form-data" onSubmit="return onSubmitForm();"> and the validation script uses this: Code: <form name="theform" method="post" action="#" onSubmit="return check(this);"> I am trying to get them both to work. How would I do that, please? The test site is he http://proofreading4students.com/contact_test.asp Thanks for any help. Steve I'm trying to add an event handler for to my body, and for some reason which I can't figure out, it only works on Google Chrome.

body.addEventListener("load", Foo(), false);
function Foo(){
addEventListener(document.getElementsByName("start"),"click", alert("hello"), false);

I have the Jplayer.swf in multiple folders too to prevent path errors, but that still seems to not help. Anybody? I am very new to coding, I am currently working on this design as my very first: http://img822.imageshack.us/img822/6533/unled1pd.jpg. I am currently working on the Image slider which is on the left side next to the login bar and headlines. I don't know where to start with this. If someone could walk me through or help me in anyway i would greatly appreciate it. Here is my current project LIVE: http://visionarycreativegrp.com/Demos/ForSale%20RED/# Hey, I'm not very good with JavaScript, I'm a beginner. I'm wondering why my image won't appear? This is the script: PHP Code: <script> function toggle5(showHideDiv, switchImgTag) { var ele = document.getElementById(showHideDiv); var imageEle = document.getElementById(switchImgTag); if(ele.style.display == "block") { ele.style.display = "none"; imageEle.innerHTML = '<img src="localhost/haha.jpg">'; } else { ele.style.display = "block"; imageEle.innerHTML = '<img src="localhost/haha.jpg">'; } } </script> And this is the HTML: PHP Code: <div id="headerDivImg"> <div id="titleTextImg">Click below!</div> <a id="imageDivLink" href="javascript:toggle5('contentDivImg', 'imageDivLink');"><img src="localhost/haha.jpg"></a> </div> <div id="contentDivImg" style="display: none;"> <form> <input type="text"> </form></div> What's the issue here? Thanks. Does anyone know why Lightbox images would be displaying in reverse order? The numbers are correct but it pops up on the last one and I have to hit previous to get to the front.
hey guys im not quite sure how to explain this but i have a installed something called "hostpay" if any of you are familular with is, its on an client management system which has everything in it using ruby which was created by my provider. in it has a domain search and to use the domain search i use this code Code: <form method='get' action='http://www.nandahosting.co.uk/manage/dac' onsubmit="return check_domain_input()" accept-charset='utf-8'> <input type="text" name="domain" value="Domain Name Search..." onclick="this.value='';"/> <input name="search" type="submit" class="btn" value="" /> </form> but it will only work if you use that code inside the hostpay template files which was created by my provider. the hostpay is installed to a directory called "manage" What i am trying to do is to get a domain search box to work outside the hostpay folder(sent the information accross to the hostpay template, whatever is typed in the domain search box then search for the domain) i know this is possible as i have seen other people do it but not sure how to do it myself. for examlpe: www.pixelinternet.co.uk/domain-names.html (they have a domain box on that page which transferes it over, they have hostpay installed to a directory called "piXel") how do i alter the code i put on here to do what i want it to do? thankyou very much Quote: Hi, below code is only working in Firefox but not in Internet Explorer.

The following code is working accept for the part where the original image (Main Image) is replaced with either Image1/Image2 when mouse over occurs but wont revert back to its original image (MainImage) once onmouseout? There-in lies my problem: Code: <body>

P.s something I found strange when loading my page it seems to load twice with a defining click. Very annoying and wonder if it's possible to remove that bit too. Thank you very much for any help. Hello guys I am doing a simple calculation. Here is the code Code: dose=1 A = document.rhogam.bleed.value B = document.rhogam.volume.value dose= (A*B)/3 dose=Math.round(dose*10)/10; this works fine and gives me an answer rounded to the tenths spot. the next step i need to do is round up by one if the tenths spot is less than 4 or round up by 2 if the tenths is 5 plus example 3.3=4 3.6=5 The code issue I am having is how do I read the tenths place in my result so that I can act on it? Thanks Jeremy |
