JavaScript - Quick Bool Check Problem.
I thought this would have worked but it doesn't seem to. Not very familiar with java script anymore I guess. Someone see what I am doing wrong?
Code: <style type="text/javascript">
var contact = document.getElementById("contactPage") ? true:false;
var projects = document.getElementById("productPage") ? true:false;
var about = document.getElementById("aboutPage") ? true:false;
var home = document.getElementById("homePage") ? true:false;
var checkPage = function (contact, projects, about, home)
{
if (contact === true)
else(projects === true)
else(about === true)
else(home === false)
document.getElementById("homePage").style.display='block';
};
checkPage(contact, projects, about, home);
</style>
Similar TutorialsHow do I do this equivalent function in javascript? Code: int x = 0;
int y = 1;
convertBool(x);
convertBool(y);
private void convertBool(obj)
{
bool rtnB = Convert.ToBoolean(obj);
string TorF = (!obj) ? "true" : "false" ;
Console.WriteLine(TorF);
}
// code would output
// false
// true
I am trying to pass a bit by my function call Code: function fxn(obj){
document.getElementById('box').style.display = (!obj) 'block' : 'none' ;
}
code somewhere else...
onmouseover="fxn(1);" onmouseout="fxn(0)"
I know I could do it via if obj != 0 or if obj == 0 but I want to be able to convert the bool- I know how to do it other ways but if js does not support a "one liner" I will do it via int compare I can not figure out why my function is not working or why my alert does not pop up.. can anyone help? When you enter a total in the box, all I need to do is have a total with shipping show up in an alert box. (Minimum shipping is $1.50, if the total is over $25 shipping is 10%) <code> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>CalcShipping</title> <meta http-equiv="content-type" content="text/html; charset=iso-8859-1" /> <script type="text/javascript"> /* <![CDATA[ */ function calcShipping() { var priceInput; var total; priceInput = document.form1.subtotal.value; if (priceInput <= 25) total = 1.5 + number(priceInput); } else { total = number(priceInput) + (number(priceInput) * .1); } window.alert("Your total is $" + total + ); /* ]]> */ </script> </head> <body> <h1>To find out your shipping costs, please enter your purchase price:</h1> <form action ="" name ="form" method = "post" onsubmit="calcShipping();"> <div style="text-align: center"> <input type="text" name="subtotal" value= ""/> <input type="submit" value ="submit"/> </div> </form> </body> </html> </code> this is my js for all checkbox to be check and uncheck all the item. when i have several item to be checked, it successfully check all with the function. but the problem is when i have only 1 item in the list to be checked. it will not check all or uncheck all when i click the check all function. pls advice. Code: <script language="JavaScript">
<!--
<!-- Begin
function CheckAll(chk)
{
for (i = 0; i < chk.length; i++)

On this webpage http://www.corkdiscos.com/testimonials.html i have a like button. when a user clicks like a comment box appears. when i unlike the button the comment box disappears this is ok but when a user has already liked the facebook page and comes to my webpage the comment box does not show. so im looking for a piece of javascript to check if a user has like the button on my page and if so to show the comment box. please check my source code of the website http://www.corkdiscos.com/testimonials.html to see what i have so far. any help would be greatly appreciated Hi guys. I'm working a bunch of pre existing code on a CMS. Just after a quick fix. Doing a show/hide thing on a particular div somewhere on the page depending if a checkbox is ticked or not. Currently there is 3 checkboxes that are dynamically added through the CMS. Here's simplified version of the form: Code: <form id="simplesearch" name="simplesearch"> <input type="checkbox" onclick='showhidefield(this.value)' name="meta_data_array_search_criteria[custom_profile_type][]" value="5" class="input-checkboxes" /> <input type="checkbox" onclick='showhidefield(this.value)' name="meta_data_array_search_criteria[custom_profile_type][]" value="4" class="input-checkboxes" /> </form> And here's the javascript I was playing with. Code: function showhidefield(id)
{
if(document.simplesearch.meta_data_array_search_criteria[custom_profile_type][''].checked) {
document.getElementById("profile_fields_wrapper_" + id).style.visibility = "visible";
}
else
{
document.getElementById("profile_fields_wrapper_" + id).style.visibility = "hidden";
}
}
Problem I'm having is how do i do a check to see if those checkboxes are checked in the javascript with those name arrays? How do i separate them? 'm guessing I have to loop through them or something?Hopefully that make senses - it's late here and I'm losing the plot Any pointers would be gratefully welcomed Ok, this might sound stupid but I swear, it's about to drive me crazy. how does one check whether or not a javascript "global" variable is undefined that will work with IE? I've tried each variation of code and checked countless forums: Code: if (saved == undefined || saved == null) {
alert('saved');
saved = new Array();
}
returns no error and nothing happens Code: if (saved == 'undefined') {
alert('saved');
saved = new Array();
}
-- returns error = saved is null or not an object Code: if (typeof(saved) == undefined) {
alert('saved');
saved = new Array();
}
returns same as above help me please, I'm confused more then anything. the link is also: http://doodlekins.hcents.com/designer Basically the if statement isn't returning true and nothing on the inside of it is ever happening. ok so im making a runescape private server and i have all the files and i compile and i only get 1 error. witch is the following. http://imageshack.us/content_round.p...upload&newlp=1 can anyone help me out pleasE?

Hope you guys can help me out :/ I just feel like I am doing something totally wrong. I am new to java and tried writing the code for practice but it doesn't seem to work <html> <Head> <title>Discount</title> <script language ="Javascript"> <!-- function CalculateBalance(numItems,totPrice,discount) { var balance; balance = (1 - discount)*totPRice; alert ('Your balance is $'+balance +' Thank You.'); document.write("<br>YOu bought "+ numItems+" items for $"+totPrice); document.write("<br>Your balance is $"+ balance+" your discount was"+discount*100+"% Thank you"); } //--> </script> </head> <script language ="Javascript"> <!-- var discount; var numItems = parseInt(prompt('HOw many time did you buy [ >=12 is 20% and >= 6 is 10% discount]',"0")); alert ('You bought '+numItems +' items.'); document.write("You bought "+ numItems+" items."); var totPrice = parseFloat(prompt('The total price that you paid was',"0.0")); if(numItems >= 12) {discount = .2;} else if (numItems >=6) {discount+ .1} else {discount = 0;} CalculateBalance(numItems,totPrice,discount); //--> </script> </html> It only prints to the screen the number of items I bought Don't even know where to post this as I have never thought about it; I've just made my game have a image upload script in, and a album showing the users images. How could I make have a link saying "Copy Link" that if clicked will copy the picture url to clip board. I've seen places like w3schools use in but not as tuts though. Please this will really help, desplayin the link is ugly EDIT: I've found the following code but I don't understand how I turn it into a link or button. Code: <script>
window.clipboardData.setData('text','This has been copied to your clipboard.');
</script>
Urghh I've always done it this way but it's nagging me. Is there a better way of checking if a value is equal to 1 or 2 or 3 than doing it this way. Code: if(var === Cat || var === Dog || var === Chicken || var === Frog) Not working code ^ lol Cheers guys I know that global variables are properties of the window object... so does that mean that local variables are properties of the function they belong to? And does that mean that functions are methods of the window object and that nested functions are methods of the function they belong to?
Hi all, This is a quickie. I'm a JavaScript newbie. I have had a crack programming with it but I need some questions answered to help my understanding. Please tell me the convention that governs the use of "" and '', because so many articles that I am finding in my learning journey are using them interchangeably and it is so confusing. For instance, but not limited to, take the id and value tags of an <input type=... of whatever. Is it best to use '' or "" for the labels you give? What is the convention governing the use of a ; (semicolon) because so many people use one where others do not. I'm under the impression it is an EOL terminator like in Bash, right? So it goes after declaring variables or after something within an if statement perhaps? Thanks QF Hi, I have the below code, but got a problem with it. The problem is, if you click Test 1, then Test 2 you have to click Test 2 twice, this also repeats for Test 3, 4 and 5. It is the same with onclick. I presume the problem is in the javascript code, but not sure where to start. Can anyone help <html> <head> <title>Test JS</title> <script language="javascript"> <!-- var state = 'none'; function showhide(layer_ref) { if (state == 'block') { state = 'none'; } else { state = 'block'; } if (document.all) { //IS IE 4 or 5 (or 6 beta) eval( "document.all." + layer_ref + ".style.display = state"); } if (document.layers) { //IS NETSCAPE 4 or below document.layers[layer_ref].display = state; } if (document.getElementById &&!document.all) { hza = document.getElementById(layer_ref); hza.style.display = state; } } //--> </script> </head> <body> <p><a href="javascript:showhide('sect1');">Test 1</a></p> <div id="sect1" style="display: none;">Test 1 content</div> <br><br><br> <p><a href="javascript:showhide('sect2');">Test 2</a></p> <div id="sect2" style="display: none;">Test 2 content</div> <br><br><br> <p><a href="javascript:showhide('sect3');">Test 3</a></p> <div id="sect3" style="display: none;">Test 3 content</div> <br><br><br> <p><a href="javascript:showhide('sect4');">Test 4</a></p> <div id="sect4" style="display: none;">Test 4 content</div> <br><br><br> <p><a href="javascript:showhide('sect5');">Test 5</a></p> <div id="sect5" style="display: none;">Test 5 content</div> </body> </html> I tried posting this: <button type="button" onclick="JavaScript:alert('Let's assume.....')"> <img src="question.jpg" alt="Click here" /> <br />Click for Answer!</button> and it shows the button with the picture, but I am unable to click it.

Hi... i have this code: <script type='text/javascript'> cookie_name = GetCookie("href_location"); if(cookie_name){ alert("Cookie found, redirecting to stored cookie."); document.location.href=cookie_name; } </script> I will like to create a iframe using the info from the "cookie_name" value <iframe name="FRAME1" src="cookie_name" width="350" height="320" frameborder="0" scrolling="auto"></iframe> I have a script that set a cookie with the value of a chosed website, what i need now is to create an iframe with that value. Any help will be apriciated. Sorry for my poor enlish using jquery and cookie plugin. i made a popup window. when the user clicks on a check box the window closes, forwards them to a new page, and then sets a cookie. i need it so that when they go back to the original page (where the popup came from) if the browser detects the cookie then the popup does not occur. I do not know why this does not work because when I alert the value of the cookie out, it gives me the correct number. something must be wrong in my logic ? code on the base page. Code: <script type="text/javascript">
var test123 = $.cookie('FBCheck');
if ( test123 != 1212){
function popup(Site)
{
window.open(Site,'PopupName','toolbar=no,statusbar=no, location=no,scrollbars=no,resizable=no,width=350,height=500')
}
}
</script>
code on popup (both files are in same directory) Code: $(document).ready(function() {
$("#Cbox").click(function() {
window.open ("http://www.google.com", "Google");
window.close();
$.cookie('FBCheck', '1212', {expires: 365, path: '/'});
});
});
The jquery source is installed as is the plugin. Thanks so much for your help in advance! I want to create dynamic Select option in form, I want that whenever user clicks on add member button then new row will get added & i have done that by taking help of DOM createElement method & I want that by using same, I want to create select option drop down list.
