Object Property That If Greater Than One Will Cause A Delay(timeout)?
Nov 2, 2009
I want to call a function through a property of an object indefinite times, so i want to be able to pass a value to some other property (inc for example), with the number of times that function was called (gen). If it's not the first time it's called i want to cause a delay ( 5sec for example).I'm currently doing it with a setTimeout but it isn't for sure them most elegant way to do it.
I want to be able to display the whole contents of a text file containing 4 paragraphs of text, on a static web page, as soon as a video finishes playing on the page. The video is to be set to autorun as soon as the page loads in the browser.
The text file mentioned above, is to remain hidden when the page initially loads and the video is playing. Please I need your advice about what JavaScript code to use to achieve this effect, and where to place the code in the HTML code of the web page. I am new to website design and the use of JavaScript code.
I have seen examples of code used for the timed delay of the display of an image file, after a video has finished playing. I do not know how to apply this to the display of a text file.
I have an object with a single Method to load content from a xml file. The problem is... how do I add a property to the object to store the data loaded?? I tryed adding a simple Array inside the object, but didn't work.
({}["toString"]) - function alert("toString" in {}) - true
But I want to only find a property that is defined in the object - not in a prototype.
for(var prop in {}) { alert(prop); }; // toString not found.
It seems that operator 'in' is overloaded. 'in' during iteration: look in the property. 'in' in a boolean conditional: look in the object, then up the prototype chain.
I want a way to get only properties defined within the object itself, not it's prototype. Is there no simple way?
With something like this : <form name="a"><input name="name"></form> Is it possible to get the name of the form (a) and access the input object (name) too?
I have a JS script that presents a series of "pages" with different questions inside a single HTML file, by rewriting certain <div>s. I have an object like this that contains the questions and information about answer labels etc (the idea is that this should be easy to modify for someone who doesn't know JS):
I have situation that when my page is loaded i create js object <html> ... <script> function Page() { this.page = 0; this.result = 0 this.resultCount =1; this.currentPage =1; } MyPage= Page() </script> then in my javascript function i use object like this:
function getPage() { if(!MyPage) { MyPage = new Page(); } return MyPage; }
but there is one problem: MyPage lost one of the property, currentPage. When i do alert(MyPage.cuurentPage) shows mi undefined. After object initialization everything seems to be alright, currentPage is set to 1 but when i Try use MyPage in my js code is already set to undefined. What happen? What I'm doing wrong?
I want to be able to set a property on a private object by giving the not notation path to the value. The difficulty is that this object is within closure so I can't access it directly to set the value the normal way (eg. dot.notation.path = 'new value'). This seems weird but I can't think of the obvious way.
Example:
// setter function function set(path, change){ var privateObject = { a: 'a',
I am doing javascript from a book called "Prentice Hall(which sounds very masonic) : Javascript by example".
my question is this. I am doing an practice dealing with "defining methods for an object" now i used this code verbatim
[Code]...
I did this code in the book exactly. I am just trying to warp my head around this and want to understand how is this an error when it is just the crating a new property.
I've ammended my code now so that I'm using objects, constructors and prototypes.
If I use the standard constructor.prototype.functionname = (){......} type of setup it works okay.
However I'm now experimenting with overwriting the prototype with a literal. As in the code below. i.e. constructor.prototype = {functionname : function() .......
Doing it this way my first new object instance fails. The subsequent new objects are fine.
I ran a check on the properties of the 1st object with '!hasOwnProperty and name in' and the result is that the prototype (or pointer to a prototype) is missing.
So the first new object of FontTrans (oH) has
Code: 1 property is Heading . . 9 property is Delay
I've created a small AJAX library for our application. We send the response data back as JSON in responseText. So far so good.
Before we invoke the response handler, I'm putting the eval'ed responseText in the request object like so:
Code: req.respText = eval('(' + req.responseText + ')'); This works in FF but breaks in IE 6. (*gasp*)
I finally got the Microsoft Script Editor yesterday, so I could play with the values and see what was going on. Kind of... I'm still in the dark. For some reason, it won't let me add a property to req. Can anyone explain why/how it prevents me from doing so?
Conceivably I could add the eval'ed responseText to the response handler function, but that would break the API, and would require us to modify a bunch of existing functions.
I need to acsess an object property via variables, but don't get ahead.
Example:
var property = height;
"height" is a property of the object "flower". Now, I need a possibility to access "flower.height" with my variable property, means -->"flower.property" I tried everything like "flower.[property]" "flower.['property']" etc. but nothing did help.
I'm trying to come up with a swipe gesture for part of the mobile version of my website. Right now, I'm just playing with mouse movements instead of the touch events so I can play with it on my computer rather than having to load the page up on my iPhone every time. Here's the problem: onmouseup, I run a calculation to determine where the closest element is to the edge of my container. Whichever one is the closest, I do a simple animate() to that element. It looks like this:
When I try this the button text is changed and the button is disabled, but the form doesn't submit. In IE I get an error that points to theline that says:
b.form.submit();
and the error:
Object doesn't support this property or method
What's the difference between doing this code directly in the onClick event and doing it in a function?
Hi, I am attempting to create a script in which object A contains an array of "objectb" objects. An overview of the code is posted below. When I attempt to access "myObjArr" array like this:
function JGallery(){ this.name="defaultGallery"; this.images=[{//some JSON here}] this.render=function(){
[Code].....
I've tried to debug it in firebug, but I guess there is a problem with the scope of the 'this'. The 'this' in
//i want append div with id of the name property of jgallery class $("<div></div>").appendTo("#container").attr("id",this.name); seems to refer to the iterator in the $.each().
I've tried to do this.this.name but it still doesn't work. Is there any way to allow me access the property of the Jgallery class?
appears only in IE: l2 = obj.parentNode.getElementsByTagName("select")[0].value; --> object does not support this property or method var l2 = obj.parentNode.getElementsByTagName("select")[0].value;
