JavaScript - Change Background Image With If Statement Or Call Function Inside Of If?
Basically I want to have a different background image for every time of the day.
The function by itself works okay with onclick or onload placed in body. Code: function changesky()
{
document.getElementById("sky").style.background="url(back_morning.jpg) repeat-x";
}
What I want to do is have my background change in addition to a message. So instead of just "Good Morning" text I also want the background to change. Code: if (time>=4 && time<12)
{
document.write ("<p>Good Morning!</p>");
document.getElementById("sky").style.background="url(back_morning.jpg) repeat-x";
}
Tried this, but it didn't work so what's the format for calling a function inside of an if statement? Or what other method should I use to do this? Similar TutorialsIs it possible to call a function inside of the load event ? Excuse the terminology I'm completely new to all of this, but for instance. I have a function that gets the value of a cookie, and I would like to call the function inside of a load event so the cookie value is part of the string and it gets generated dynamically whenever the load is executed. Something like this: Code: $("#FTPContents").load("functions/testftp.php?HASH=Get_Cookie("User")(&reload=<?php echo $_SESSION['currentdirectory'];?>");
The Code: HASH=Get_Cookie("User")
is the part i'm referring to. I'm sure if it is possible then that syntax is wrong, can it be done ? hi i'd like to ask how can i ask for a function inside a for loop , if i remove the loop the code works fine but i need it for 10 rows . please help , here is the code PHP Code: $content .=' <table cellspacing="2" cellpadding="2" border="0" align="center" > <SCRIPT LANGUAGE="JavaScript" type="text/JavaScript"> function doCalcAndSubmit() { // get both values kolicina1 = document.forms["vlez1"].kolicina.value; cena1 = document.forms["vlez1"].cena.value; // do some calculation vkupno1 = kolicina1 * cena1; // set the value in the right field document.forms["vlez1"].vkupno.value = vkupno1; } </script> <form id="vlez1" name="vlez1" method="POST" action="index_execute.php" > <tr valign="middle"> <td></td> <td align="center"><b> Sifra : </b></td> <td align="center"><b> Kolicina : </b></td> <td align="center"><b> Cena : </b></td> <td align="center"><b> Vkupno : </b></td> </tr> '; for($t=1;$t<11;$t++) { $content .= ' <tr valign="middle"> <td>'.$t.'.</td> <td><input type="text" id="sifra" autocomplete="off" name="sifra['.$t.']" align="middle" onblur="normalField(this);" onfocus="fireKeyListener_sifra(event); highlightField(this,1);" onkeyup="getList_sifra(event);" size="25" value="" /></td> <td><input type="text" id="kolicina" name="kolicina['.$t.']" align="middle" size="25" ></td> <td><input type="text" id="cena" name="cena['.$t.']" align="middle" size="25" onblur="doCalcAndSubmit();"></td> <td><input type="text" id="vkupno" disabled name="vkupno['.$t.']" align="middle" size="25" ></td> <input type="hidden" name="hidden_data" value="'.$data.'"> </tr>'; } $content .= '<tr> <td></td> <td></td> <td align="center"><input type="submit" id="submit2" name="submit2" value="Potvrdi" ></td> </tr> </form> </table> '; Is there a way to call javascript functions based on the text between a span element? In other words if I have <span id="mySpan">Bronze</span> then it will call a javascript function but if I have <span id="mySpan">Silver</span> then it will call a different function? Thanks!

I'm using this to call the function from flash: Code: ExternalInterface.call("pgcover");
I know that this is calling the function as I have set it trigger an alert action and this comes up properly. But I don't want the function to trigger an alert, this is just for testing purposes. I instead want it to change the styling on a div. I have set up a test page where I have asigned the function to a button and this works, the div display changes from block to none. When I get the swf to call the function setup to do the same thing, nothing happens. Code: function pgcover()
{
document.getElementById("unlayout").style.display= "none";
}
My swf is embedded in the html page that the javascript is on, I have checked all code and have rulled out spelling mistakes etc. Any help with this would be amazing as it is driving me crazy. For the sample code: Code: <form name=form>
<ul>
<li><input type="text" onkeyUp="calc1();" name=x ></li>
<li><input type="text" onkeyUp="calc2();" name=y ></li>
</ul>
</form>
<script>
function calc1() {
document.form.y.value = (10 * document.form.x.value).toPrecision(5);
}
function calc2() {
document.form.x.value = (0.1 * document.form.y.value).toPrecision(5);
}
</script>
How can I use a checkbox to : (1) Upon check, change the current values to toExponential(5) format (2) Use a different script and/or function that would then calculate with toExponential(5) [as opposed to the hard coded toPrecision(5) in the current functions. (3) Upon unchecking, the result should should go back to Precision and change the function and/or script back to the original. Hi Guys, I am trying to make a change to my website so when someone clicks on the chinese flag image, for example, a function which put the clock forward a few hours.

Hi Complete novice with Java so need some help please! I want to put a button on a website that when clicked changes the background. The button needs to be an image. For example, click on the image and it makes the background image1 and then click again to switch to background image2. The image/button that is being clicked will be 2 images (one says "turn lights on" then when clicked shows other image "turn lights off") I have managed to pick up bits of code from the net that change the background and got another code that makes 2 images a toggle button. The button changes the background on the first click but no back again on the second click. I guess it needs an if/else statement but not sure.

Thanks in advance!! Hi, I am hoping I just need to be pointed in the right direction with this. I have Page1. When Page1 body onloads it uses Ajax to call PartA Within PartA I have a message board so members can write messages which will be sent to my database in PartA[1] and immediately posted for view on to PartA[2]. As I want to have my request to the server updating regularly I want to have PartA[2] on a timed loop to refresh - I do not need the content of PartA[1] to refresh. So the order of events would look like this: Page1 | onload call | v PartA / \ V V PartA[1] PartA[2] (loads once) (constantly refreshes) What I am not sure about is that I have <body> and <head> attributes in Page1 only. I have already used my body onload to call PartA (and can't use it to call PartA[2] before PartA has loaded anyway). I do not want the user to have to click a button or do anything to call up PartA[2]. So my question is how would I get PartA[2] to automatically load within PartA? I hope I have made this clear, but if I haven't let me know and I will try again. i keep getting error Call to undefined function codeandurl() below is my code PHP Code: <?php $value= strip_tags(get_field('link',$post)); $resultid=get_field('resultid',$post); codeandurl($resultid,$value); ?> <div id="result"></div> <script type="text/javascript"> function codeandurl(resultid,url){ $( "#result" ).text(resultid); $( "#result" ).dialog({ modal: true, buttons: { Ok: function() { $( this ).dialog( "close" ); } } }); window.open(url); return false; } </script> <p> <script type="text/javascript">// <![CDATA[ var metrics = { "mm" : 1, "cm" : 10, "m" : 1000, "inch" : 25.4, "foot" : 304.8 }; function convert(num, dec){ var val = document.getElementById("fromVal").value; if(isNaN(val)){ return } function roundNumber(num, dec) { var result = Math.round( Math.round( num * Math.pow( 10, dec + 1 ) ) / Math.pow( 10, 1 ) ) / Math.pow(10,dec); return result; } document.getElementById("toVal").value = val * metrics[document.getElementById("fromSystem").value]/ metrics[document.getElementById("toSystem").value]; } var interval = null; function watchChanges(){ interval == null ? setInterval("convert()", 500) : clearInterval(interval); } // ]]></script> </p> <table> <tbody> <tr> <td><input id="fromVal" style="width: 100px;" onfocus="watchChanges()" onblur="watchChanges()" type="text" /><select id="fromSystem" onchange="convert()"> <option value="mm">millimeters</option> <option selected="selected" value="cm">centimeters</option> <option value="m">meters</option> <option value="foot">feet</option> <option value="inch">inches</option> </select></td> </tr> <tr> <td colspan="1" align="center">=</td> </tr> <tr> <td><input id="toVal" style="width: 100px;" type="text" disabled="disabled" /><select id="toSystem" onchange="convert()"> <option value="mm">millimeters</option> <option value="cm">centimeters</option> <option value="m">meters</option> <option selected="selected" value="foot">feet</option> <option value="inch">inches</option> </select></td> My issue is that I have a javascript function applied on page load via an addLoadEvent function call in the head to every row (dynamic number of records retrieved) on a table. On every row of the table I also have an element (image or button) that performs a different function that is assigned on the element itself. Unfortunately, when I click the element it also performs the function that was applied to the row in the page load. Is there any way to not call this function on element click? I know usually you include code, but due to the nature of the work I am limited in that respect. Basically its: Code: <script type="text/javascript">
addLoadEvent(function() { function1(1); })
//function1 makes the table rows do something appearance wise.
</script>
<tr>
<td></td>
<td></td>
<td>
<img src="pics/delete.png" alt="Delete" onclick="function2();">
</td>
</tr>
I apologize if my post doesn't conform to the general guidelines of proper posting on this board. I'm new on this site. Code: <html>

This is a very basic version of what I am trying to do. I have a dynamic list which is set in a table. When clicked, a function is run to set up a new list.. The reason I explain that, is that I need to keep it dynamic. Now for the problem: When I run this page, I have the button made right away, then when clicked it creates the new button. The new button should also run the function to create the new button again, but when I click it, I only receive "error on page". I don't know if there is a better way to go about this, but as for this route, I am stuck. Any help is greatly appreciated! -Shane |
