View 1 RepliesHow can retreive the URLs from browsers history. My requirement is to show the links which user visited before visting my website as thumnails.
View 1 Replies View Relatedis there neway using javascript that you can detect if a vistor has clicked a link?
the reason i ask is that i need to make only certain links on an area of a page to be a certain color if they have been linked, but other ones remain unaffected. i only have control over a few links, as it is an asp application for someone to download and have inside their pages
I just finished adding a purchased shopping cart to a site and it's part php and part javascript.
The first problem is this little piece of code:
<A HREF="javascript:history.go(-1)">Back<A>
It works fine in IE6 but, wil only work once in Netscape6.2...What gives?
I search for a way in javascript to prevent browser from caching my
HTML page in its "history" and "temporary files" if there is any .
I'm attempting to use the javascript 'history.go(-1);' to make a page automatically return to the last page a user visited. At the moment, I can get this to work ONLY if I insert a link into the page.
What I want to happen is, the page autmatically sends the user back to the previous page after a set time. I have this for my JS:
function backtomusic() {
window.location = history.go(-1);
}
And in the body section of my page I have:
<body onLoad="setTimeout('backtomusic()', 3000)">
When it runs I get an error saying 'undefined' in the browser address bar
Any ideas?
I'm designing a web site and I designed an error page with .htaccess so that when someone types in an incorrect URL, it takes them to my customized page. Well, I used server-side programming to make it log the bad URL and check against a database if the there is a good URL matching the bad one. If so, it redirects to that page instead of giving the error. It's a good, well-written script done by me, I'll give it to anyone that requests it.
What I want to know is if JavaScript can prevent a page from being logged in the visitor's browser history.
You see, when they click the back button, the revisit the error page and it relogs the bad URL.
Is this possible in Javascript? Code:
Can someone show me how I can have:
<a href="javascript:history.back()" name="Back" value="Back"
style=width:40px;float:right;margin-left:0px class="button" >Back</a>
but since this href exists in a frame, it only pertains to this frame?
Determine what the previous page was that the user was viewing, even if the user arrived at my site by through the use of a browser function (history, location bar, refresh, etc.). Is this possible?
I'm not wuite sure how document.history functions - what degree of privacy is given to the user and to what extent can web pages get URLs from the user's history?
The IE developer toolbar's DOM inspector shows the OBJECT tag and the PARAM
tags inside it, and if I don't have the Javascript in an external file, I'll
get the "click here to activate" tooltip and the border around what is
supposed to be the Flash movie. If I right-click inside the border, I get the
Flash context menu. The movie just doesn't load.
<html><head><title>foo</title>
<script>
function foo() {
AXObject = document.createElement("object");
AXObject.type="application/x-shockwave-flash";
AXObject.data="flashtest.swf";
AXObject.width="200";
AXObject.height="50";
AXObject.style.visibility="visible";
var p=document.createElement("param");
p.name="movie";
p.value="flashtest.swf";
AXObject.appendChild(p);
var p=document.createElement("param");
p.name="quality";
p.value="high";
AXObject.appendChild(p);
document.body.appendChild(AXObject);
}
</script>
</head>
<body id="foo" onload="foo()">
</body>
</html>
Does Javascript supply a function that destroys an object? If so, is there a
dependancy on Javascript version?
Is it possible to have something like the following so that 'three'
can access 'one':
var x = {
one: 1,
two: { three:this.one } // Or parent.one ?
}
If not (which I have nearly come to a conclusion on) what is the next
best way to accomplish this?
I want to access the features of a plugin without actually embedding
it into a page. Is this possible? Eg
The code to embed the object into a page is:
<OBJECT classid='CLSID:7FA62735-AHC3-14d2-9F81-00114B3245C5
codebase='http://www.test.com/plug.cab#version=3,1' "id='myPlugin'
height=Ɔ' width=Ɔ'>
<EMBED type='application/x-myPlugin' name='myPlugin' hidden='true'
src='in.txt'></EMBED>
</OBJECT>
I could simply add this using document.write, but for various reasons
I dont want to do this.
I would rather do something like:
var plugin = (navigator.mimeTypes &&
navigator.mimeTypes["application/x-Web-Plugin"]) ?
navigator.mimeTypes["application/x-Web-Plugin"].enabledPlugin : 0;
myObj = new object("CLSID:7FA62735-AHC3-14d2-9F81-00114B3245C5");
myObj.pluginMethod
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 have the following Javascript code
function Obj()
{
obj.squares = new Array();
}
Obj.prototype.Load= function(xdoc)
{
var goat = "head";
xdoc.ProcessNodes("squares/square", function(node)
{
alert(goat); // <-- this works fine
this.squares.push(
// do processing on node, create a square
);
});
}
Now the xdoc is another object I have, with a method called
ProcessNodes. The only important thing to know about ProcessNodes is
that it does some things, and calls its second argument (which is a
function) successively.
The problem I am running into here is once I get into the callback
function, "this.squares" is returning null ... even though it has been
initialized to an Array. For whatever reason, its like the object loses
scope when I get into the callback function. For all other intents and
purposes however, the callback function has the same scope as the
calling block (i.e. the goat variable is still accessible).
I'm trying to utilized a more object-oriented approach to managing
window events in javascript. Thus, I am creating a "controller" object
to handle events and interact with the server. However, I apparently
don't fully understand what "this" refers to. In the code below I was
expecting that when the button was clicked (handleDeleteButtonClicked
function) that "this" would be pointing at a ViewController object.
Instead it was the Button (HtmlInputElement).
<html>
<head>
<script>
/* Constructor */
function ViewController() {
this.foo = "bar";
}
/* delete button handler */
ViewController.prototype.handleDeleteButtonClicked = function() {
window.alert("delete clicked, this=" + this + " this.foo= " +
this.foo);
};
/* initializer */
ViewController.prototype.initialize = function() {
document.getElementById("delete-button").onclick =
this.handleDeleteButtonClicked;
};
</script>
</head>
<body onload="javascript:new ViewController().initialize();">
<input id="delete-button" type="button" value="Delete">
</body>
</html>
I just released javascript lib that really helps to develop robust and clear js-scenarios following the OOP directions. The library is compatible with wide range of browsers on different platforms, including Netscape 4.x, Netscape 6.x, Netscape 7.x, Opera 6, Opera 7, Mozilla 1.0, IE 4, IE 5, IE 6.

View 1 Replies View RelatedI am creating a JavaScript object which I want to use to respond to user input on a web page. The object will basically be made up of a constructor and then a selection of functions which will use the DOM to alter the appearance of the page according to the user's input. I am getting stuck because I want a form element that is being created by the object to have an 'onkeyup' event attached to it which will call another function from the same object.
Now, I understand how to attach the 'onkeyup' event to the input element I have created using the DOM. If I tell the event to call a normal function (alert() etc) then it does exactly that. What I am having trouble with is getting the event to call another function from the object that created the input box in the first place. (I don't even know if this is possible / a wise thing to do!). Code:
I have a fairly complex javascript object - containing strings and arrays - which I need to pass along to a second PHP page. Is there a way to pass this object along via POST to be picked apart by the receiving PHP script?
I could dynamically create a form, populate it with the contents of the object, then pass it along via submit(), but frankly that's an awful pain.
I'm having trouble getting the following code to work properly. Every time I try to access the private testing variable from the priveleged MyMethod it gives an error. Says it can't find testing and that it has no properties so I can't run a push() command on it.
function MyClass()
{
var testing = new Array();
// define the method
function MyMethod()
{
this.testing.push("hello");
}
// make the method priveledged
this.MyMethod = MyMethod;
}
// a test function it ensure the variables declared here are isolated
function Start()
{
var myClass = new MyClass();
myClass.MyMethod();
document.write("[" + myClass.testing + "]");
}
Start();
Can someone tell me all the OOP's that can be made from javascript.
View 3 Replies View RelatedI have a page (page 1), my page 1 has an IFRAME which loads another page (page 2).
My page 2 has a JavaScript object declared on the page: var MyObject = new Object();
I want to access this object from the parent page (page 1).
I tried:
var TempObj = document.getElementById("MyIFrame");
TempObj.document.MyObject.value = "blah blah";
But it said MyObject didn't exist.
Can someone tell me how to access it in this manner?
I got two ASP pages. One is ASP email form (I'm using Persist ASP
Email component). Another one has all file links in it. For example,
when user click Outlook course hyperlink. It will pop up another
window with outlook course PDF file. (All PDF files are already in the
server).
What I am trying to do is: When user click the "Add Email" hyperlink,
it will add that course name and filepath into ASP/VBScript Dictioanry
Object. After the user finish and click "Attach to email" button. All
the files will be attached in the email as an attachment.
Because I am not familar with VBScript. So, can Javascript add items
to ASP Dictionary Object?
Is this possible? Basically I need to grab all the flash objects on the page (done) and then set the wmode to transparent so it doesn't mess up my DHTML menu.
