I'm calling `setInterval(myfunc, 100);`.
That function receives one parameter which seems to be -3, 0, 3, 6 or 9.
This isn't a problem, but I'm wondering what it is. Does someone know?

Here is a small snip-it that I'm using to colour lines of a table as a user rolls over them.
function colour(){
var rows = document.getElementsByTagName("tr");
for(i=0;i<rows.length;i++){

I have a main page that opens a pop up window when the user clicks a
link. The pop up window is a menu and when the user clicks the item, it
populates a form input element on the 'parent' window.
My question is: this new populated form element is the value that I use
to change a style.
onchange does not watch this form element because of getelementbyid, so
it doesn't trigger the function needed to change the style. onchange
works fine if I just manually input a value into the text box.
Any other way to fire the function off when the user picks their
selection from the pop-up window? I was thinking I could use
window.opener.function()? But how do I pass the form from the parent
window? From the pop up window, I don't use this.form, what do I
use?something like window.opener.form[0] ?
I'm a PHP developer that needs to user javascript to open a window prior to a _POST call.
PHP Code:
<title>test</title>
<SCRIPT language="JavaScript">
function newwindow()
{
var myForm = document.header;
var txtValue = myForm.txtUsername.value;
var txtFileName = "lost_logon.php";
[Code]....
I need the window.open to open a new window with arguments attached. For example is the username is bigbob the call should be lost_login.php&user=bigbob. How do I pass the argument?
This is related to the pop-up window. Below is the function related to pop-up window.
function openPopUpDetailsMultiple(seqNum ,controllername ) {
if (!popUpDetails||popUpDetails.closed) {
popUpDetails=window.open("GetSCEventAddData?schandle=<!.schandle>&objID=<!.objID>&seqnum="+seqNum+"&controllername="+controllername+,"popUpDetails","toolbar=1,location=0,scrollbars=1,width=600,height=300,resizable=1,left=200,top=200");
}else{
popUpDetails.focus();
popUpDetails.location="GetSCEventAddData?schandle=<!.schandle>&objID=<!.objID>&seqnum=" + seqNum;
} }
The above function is being called in the href link as stated below:
//Draw the event table
document.write("<table border=1 bgcolor=" + contrColor + " cellpadding=3 cellspacing=0 width=750><tr><td width=130 valign=top class=body align=center rowspan=2>" + scEv[i].sceTime + "<br>" + scEv[i].sceDate + "<br>" + scEv[i].sceCntr + "</td><td width=60 valign=top class=body align=center><img src=images/NsaAlarm"+sevIcon+".gif border=0 height=16 width=16 align=middle alt='" + sevText + "'></td><td width=230 valign=top class=body align=center>" + scEv[i].sceCode + "</td><td width=230 valign=top class=body align=center>#" + scEv[i].sceSeq + "</td></tr><tr><td width=620 valign=top class=body colspan=3>" + scEv[i].sceDesc + "<br><table border=0 cellpadding=0 cellspacing=0 width=100%><tr><td class=body><a href=javascript:openPopUpCAC('" + scEv[i].sceCAC + "')><img src=images/NsaTools.gif border=0 height=16 width=16 align=middle alt='View corrective actions'>Corrective action code: " + scEv[i].sceCAC + "</a></td><td align=right class=body><a href=javascript:openPopUpDetailsMultiple('"+ scEv[i].sceSeq+"''"+ scEv[i].sceCntr +"')><img src=images/NsaMoreDetails.gif border=0 height=16 width=16 align=middle alt='View more details'>More details</a></td></tr></table></td></tr></table>");
The problem I'm facing now is in this piece of code:
><a href=javascript:openPopUpDetailsMultiple('"+ scEv[i].sceSeq+"''"+ scEv[i].sceCntr +"')><img src=images/NsaMoreDetails.gif border=0 height=16 width=16 align=middle alt='View more details'>More details</a></td></tr></table></td></tr></table>");
I do not know how to send these (scEv[i].sceSeq,scEv[i].sceCntr) arguments. What might be the delimiter for these arguments.
On the ONLOAD event I would like a popup box to open. In this popup
box I need two text boxes. One for the UserName and one for the
BillingTo name. After entering these two items the user can either hit
the enter key or press the submit button. The popup window will close
and then those two text boxes in the original webpage will be filled in
automatically.
I would like to have the two fields to be validated so the popup won't
close until both text boxes are filled in.
So far I have used the function from javascript.internet.com in the
header of the original page. I have tried to make so that when the
first popup closes the second popup will open. I can get the variables
to pass the main page but I feel it would be more effecient to have
both text boxes in the same popup instead of having two. Code:
Inside of a page, there is a iFrame, which houses WYSIWYG editor.I'm trying to pass data (passedString: html, inline css, text ...) to a popup.When I pass same string to same div with id="idx" located on a page, where iFrame is located, it receives it without problems.Problem appears, when I try to pass string to popup.

I have this OO code and i want to get the setInterval to loop but when the setInterval is called, i get error saying that loop() is not define..
Code:
function setFunc(){
this.init = init;
function init(){
[Code]....
If I have some code that's a bit like this
Con = function() {
this.op = 1;
this.count = 0;
}
Con.prototype.loop = function() {
this.doNext = setInterval(this.next, 100);
}
Con.prototype.next = function() {
this.count++;
if (this.count > 10) clearInterval(this.doNext);
}
obj = new Con();
when I call obj.loop(); 'this' in obj.next refers to setInterval
and not obj . I realise I can add var ref = this; and send it with
setInterval but is there something I can do to get 'this' to refer to
obj when in obj.next?
I'm attempting to create a small function that when called upon will change the CSS background property 10 times at 80 millisecond intervals. I'm pretty sure setInterval() is the way to go about this, but I've been toying with my script for an hour and can't get anything to work.
At each 80 millisecond interval, the CSS background property should change like so:
background: url("image.png") 0 0 no-repeat;
background: url("image.png") 0 20px no-repeat;
background: url("image.png") 0 40px no-repeat;
background: url("image.png") 0 60px no-repeat;
and so on.
I would normally just use the background-position property, but it seems the hyphen throws javascript for a slip. It's really not necessary for this function, but if there's a way to use hyphens, it would be good to know for future reference.
Is some future Mozilla going to support setInterval ( <function:function>,
<interval:number> ) ?
Right now it seems to be simply setInterval ( <function-text:string>,
<interval:number> )
How would you use setInterval so that theres a delay each time javascript runs through a certain loop?
View 10 Replies View RelatedI want to use the setInterval function to animate a menu sliding down when the user clicks on a link. here's a snippet:
box.timer = window.setInterval(
function() {
box.heightCount++;
if(box.heightCount >= maxHeight) {
window.clearInterval(box.timer);
}
box.style.height = box.heightCount + 'px'
}, 1);
So this works ok in the sense that the animation is performed smoothly. But to my understanding it should expand the height of the box 1pixel every 1ms, so it should expand very quickly from the base height to the maxHeight limit, but I click on the link and it animates soooooo slooooowly -- smoothly, i mean, but it takes well over a minute to expand to the full height. I just need to speed the damn thing up! Also, if i change "box.heightCount++;" to "box.heightCount+=1;" it gets all messed up. What am I missing here?
i'm scratching my head over achieving similar results with setInterval() function, and how I can keep it from looping infinitely.
I want to do something like this:
var i = 0;
var endTime = now + ((1000*60)*2); // 2 minutes after now
while (now <=endTime) {
i = i + 1;
now = new Date().getTime();
}
document.write("total iterations: " + i);
however you can't do this because of lag issues, so i'll settle for using setinterval on its smallest interval of a millisecond, here is my attempt to translate the above to a setinterval solution:
var endTime = now + ((1000*60)*2); // 2 minutes after now
var intervalID = setInterval(loopFunc(endTime),1);
function loopFunc(endTime,intervalID) {
if (new Date().getTime() <= endTime) {
i = i + 1;
} else {
clearInterval(intervalID);
}}
as you can see I have prolbems figuring out how to stop the interval from continuing to iterate, and passing the interval id, I'm clueless Also I'm clueless on echoing the total iterations via this method.
I'm trying to build the framework for an AJAX back/forward button fixer. Basically it uses the hash fix for them (using text after the # to add history objects). To this effect, the function to check for updates has to be run every second or so. No problem, I'll just use setInterval for that.
For whatever reason, though, setInterval gives me an error. Specifically that oldLocation (global variable) is undefined (in the checkURL function). So I try setTimeout. Same thing. When I just call the function explicitly once (adding checkURL(); to the end of the script) everything works wonderfuly; it's just setting it up on a timer that messes up. Frankly, I've no idea why it's doing this. (The bug just seems so odd) Maybe a more advanced JS coder can shed some light on it.. Code:
how can i set an interval inside a class
exmpl.
var Class = (function() {
var interval = undefined;
function initInterval(instance) {
interval = setInterval("doSomething", 1000, instance);
}
function doSomething(instance) {
alert(instance.message);
}
function Constructor() {
this.message = "hello world";
}
Constructor.prototype.init = function() {
initInterval(this);
}
return Constructor;
})();
is not working correct. doSomething is not known. i think, setInterval
is not inside the class, so doSomething is private and unknown for the
interval.
I've developed a plugin for a simple slide show. and here is the code [URL] The problem is when I mouse over the pic, the console error logs: "slideSwitch is not defined" The same error would still happen if I define function slideSwitch(){} and call
setInterval("slideSwitch()", 1000);
Inside of $(document).ready(function () I have:
var refre****= setInterval(function(){
$('#mydiv').load("mypage.htm");
}, 9000);
This is working great in IE, it loads mypage.htm into mydiv every 9 seconds. If I change the contents of mypage.htm I can see it in mydiv after 9 seconds with IE, but not with Firefox.
With Firefox I can see the reloading symbol on top of the tab every 9 seconds, but I don't see the page changed.
I am new in web development. I think this problem is related to javascript, I have write script which will change images after 2sec, through setInterval function. Script is as follows.
<script>
var images = new Array ("img/1.jpg", "img/2.jpg", "img/3.jpg");
var currentIndex = 0;
function Start(){
setInterval("ChangeImage()", 2000);
}function ChangeImage(){
currentIndex++;
if(currentIndex == images.length){
currentIndex = 0;
}
document.images[0].src = images[currentIndex];
}
</script>
But when I place in img tag which is in third row div and reload page, these series of images show in first row div. It does not show where I have specified area for it in css.
First row div:
<div id="menu">
<img src="header/menu.png" name="menuImg"/>
</div>
My series of images show in this div when I load page.
3rd row div:
<div id="slideshow-img">
<img src="img/3.jpg" name="myimg" onclick="Start()"/>
</div>
I have checked there is no size issue in my images.
I just encountered a rather strange issue with setInterval() in Firefox. Take for example this code:
function test(){
setInterval("window.status+='x'", 1000)
}
test()
test()
So I call test() twice, which should mean the status bar gets appended 2x's every second. This is the case in IE6 and Opera, but in Firefox, it pauses every 2 seconds, and adds 4x's each time. Basically, Firefox seem to not update every second but every 2 seconds as a result. Anyone know what's going on?
function load(cv)
{
setInterval("checknew('cv')",1000);
}
checknew sends the number 1 or 0 depending on what load sends, and in turn, its just alternating 1/0 every second.
I am unsure how to send the number I get in load(cv) to checknew(cv) every 1 second on setInterval.
I have a script that I have tried running using both setTimeout and setInterval. It works fine in every browser except safari 3. It will run fine for a few loops and then stop.

I am trying to use the variable "theObject" to pass a value to setInterval.
But I keep getting the error that "theObject" is not defined. But I have tested it with an "alert" just before the "if" statement and I know that not only is it defined, but it has the correct value.
Why won't setInterval recognise the variable? Is there a way to get this to work?

I tried putting the method in setInterval in quotations, which runs continuously but it won't allow me to pass parameters so in turn it does nothing. The way I have it now passes parameters but doesn't run continuously.
$('#icon' + i).bind('click', function() {
var icon = this.id;

function iconExpand(obj) {
