How can I grab the keyword phrase that someone used to enter the website and then pass that through a form? I would need to know for search engines and Google AdWords as well. Does anyone know how to do this?

Is there a way to find which element in an object array the keyword 'this'
is acting upon?
For example:
function doMe(){
var aTags = document.getElementById("list").getElementsByTagName("a");
for (var i=0; i<aTags.length; i++) {
aTags[i].onclick=function() {
this.className = "myClass";
}
}
}
Inside of this function is there a way to determine where in the array this
'this' is and return the integer?
var theID = this.somethingOrOtherThatWouldGiveMeTheNumber;
var elementID = document.getElementById("myDiv"+theID);
Would like to check if there is anyway where i can use javascript to grab the keyword of .doc and .pdf file.
because when i right-click on the files, and click on properties. there will be a tab at the top (Summary for .doc and PDF for .pdf), and upon clickin there will the description, author and keywords. so im just wondering if there is any way to grab the value?
I'm having difficulties writing a script that should do the following:
1. "visit"/connect to a website
2. search after rss feeds on the site
3. grab the rss link and make it useable for other scripts (array...)
ok so I know how to do substring to read everything before a certain phrase however is there a way to read everything after a certain phrase? Ex of what this script reads and doesent read
Alex was slain by dog
Bob was slain by cat
Alex & Bob = "Var CharName" My substring reads this in this line:
Var Charname
CharName = msg.substring(0, msg.indexOf(" was"))[code].....
I am looking for a way to search another site for a specific phrase.
People are linking to my site and then I have to ask them for the page where they linked and go validate that it's there. I'd like to automate this process.
I haven't really used javascript before except for the odd snippet, and I was wondering if anyone can help me with a problem I have:
I need a script that chooses a phrase at random from 4 pre-defined lists of phrases, and does it all from the one page - rather than a separate page and a separate script for each pre-defined list of phrases.
I hope this is clear enough! Here is an example to illustrate what I mean:
This would be the text that appears on the webpage:
Click here for random Phrase Type 1
Click here for random Phrase Type 2
Click here for random Phrase Type 3
Click here for random Phrase Type 4
When clicking the first option, it only chooses from pre-defined list #1, the second option only chooses from pre-defined list #2, and so on.
It then displays the randomly generated phrase in one separate box, no matter what pre-defined list was chosen. (Although if each phrase has to be displayed in 4 separate boxes, that'd be ok too.)
I want to add a simple alternative to CAPTCHA on a form by adding a required text input - e.g.Type the word "jquery":How do I add a rule requiring a specific value?

When the user click HTML button, it will launch doSomething(). But I
want the user enter ENTER key, it will have same effect.
I am modifying the suckerfish dropdown code to use settimeout to have
a slight pause before the menus disappear to make it more user
friendly. I have hit a snag with the following statement:
li.
{
timerID=setTimeout('this.getElementsByTagName("UL")
[0].style.display = "none"', timecount);
}
If I put take the statement
this.getElementsByTagName("UL")[0].style.display = "none";
out of the settimeout function, it works. (w/o the pause, obviously).
With the settimeout function, I get "this.getElementByTagName is not a
function" error.
I have tried putting this.getElementsByTagName("UL")[0] is a variable
and then using that in the settimeout function, but then each li will
only open the very last menu in the list. (ie all the menu items open
the last sub menu) Code:
I've been searching google endlessly and I've come to the conclusion I'm not using the proper search keywords. I'm trying to create something similar to the banner/button combo you can find here:[URL]..
I assume these type of slide show buttons combos use java script and possibly php. If anyone knows the proper name for this type of slide show or can point me to some scripting
I was reading thegetting started with jquery. And got confused with use of this in these 2 code segments.
$(document).ready(function() {
$("#orderedlist").find("li").each(function(i) {
$(this).append( " BAM! " + i );
});
});
$(document).ready(function() {
// use this to reset several forms at once
$("#reset").click(function() {
$("form").each(function() {
this.reset();
});
});
When do we need $(this) and this? And what is the difference between them?
I'm trying to get the following function to work:
When called like so:
I could just give each image an ID and not use the 'this' keyword, but I haven't used it much so I'm curious about it. It's sending the image element to the function, so why can't I modify the src attribute with that information?
I'm creating a list with buttons that show and hide some of the list elements to create the effect of scrolling. I've built an scrollList object so I can apply this to any list. When you create the object and pass it the id of the <ul> and how many items of the list you want to be displayed. It will add the scroll down and scroll up links and add an Event.observe to them (I'm using the Prototype library).
This code creates the object
var main_news_articles;
main_news_articles = new scrollList('main_news_articles', 5);
main_news_articles.init();
The problem I am having is with the callback functions of the onclick event of the links (scrollUp and scrollDown). The this keyword within these functions is refering to the link and not the object.
To try and solve this I've made the title attribute of the link the same as the variable name of the scrollList object. I can reference the scrollList object like so Code:
I've just started learning jquery and have been trying to use this code which I found on this forum.I want to detect some text (addClients) in the url and add an css id to a list item with the class m1 (li class="m1") - so I get (li class="m1" id="expanded"):
This is what I have so far (which is not working)$(function() {
$(document).ready(function() {
var url = location.pathname;

I want detect if the column has red or blue, add the class on it, it's like

but I want every column 2 below red column and column 3 below blue also add the same css, how to do it?
I am looking to insert a keyword in to a javascript alert box when someone visits my website, so say they came from codingforums, it would say "Welcome, CodingForums.com Visitor". My keyword will be passed from the ad platform I am working with and shows up correctly in the tracking, so I'd imagine it's just a case of having the snippet of code for it to show in the alert, correct? If there is no keyword, I would just like it to say "Welcome Visitor" or something.

How do I take <%=Keyword%> in Javascript and break it down to arrays?
View 5 Replies View RelatedI want to use the new keyword to instantiate an object. The catch is I want to pass in variable length arguments.
Given:
function Foo () {
this.args = Array.prototype.join.call (arguments);
}var args = ["arg0", "arg1", "arg2"];
The following don't work (though I understand why):
new Foo.apply (null, args);
new (Foo.apply (null, args));
(new Foo).apply (null, args);
How to do what I want without modifying Foo's source code?

Is that it ? I can't have delete ? Or can this be written in some other way, including delete ?
My plan is to create a JavaScript class, with some functions and variables, and one of the functions is called when a user clicks on a certain element. However, I need to find out the ID of the element that was clicked (in the example, that of the <p>) for further processing. It looks basically like the following:
[Code]...
The result was very crazy, because console.log(this) gave me the node as result, and console.log($(this)) did the same only as jQuery node, but trying to find out the attribute via jQuery gave undefined as result. I haven't checked if this.id would work (should probably), but I'd prefer to keep the whole script in jQuery, if possible. I suspect it may be an overusage of the 'this' keyword, but if so, what's the proper way to do it?
I have some script like this:
// simplified to remove all the try/catches & stuff
function newXHR() {
request = new XMLHttpRequest();
XMLHttpRequest.prototype.requested = null;
return request;
}
then later:
function doRequest(url, callback) {
var req = newXHR();
req.requested = url;
// et cetera....
}
This works fine in Firefox, however the line 'req.requested = url' causes an error in IE7, (I haven't tested IE6 yet). The error is 'Object doesn't support this property or method'
So, this leads me to believe that either a) XMLHttpRequest.requested is not writable, or, b) XMLHttpRequest.requested was never created in the first place. I think it's the first option because I'm not getting an error in the newXHR() function.
I've been searching for some documentation on this but I can't seem to find anywhere if properties created with the prototype keyword are writeable in IE. Does anyone know what the problem is?
So I know all about the caviats of the 'this' keyword when calling object functions from event listeners:
Code:
var foo = {bar: true, zoo: function() { return this.bar; }};
foo.zoo();
> true
a = foo.zoo;
a();
>
And I know that I can get around this by using an anonymous function so that 'this' is preserved in it's original context:
[Code]...
But then someone pointed out this article on memory leaks when using anonymous functions to call object methods because the anonymous function gets access to ALL variables in the enclosing environment and my not be properly disposed of by the garbage collector [URL] So that lead me to think about using a "3rd-person" approach to referencing object properties from within object methods.
[Code]...
is it possible to combine the the following functions with each other in an array for example and if so, would someone be kind enough to show me how. the reasons are 1. to see if it is at all possible and 2. to learn so that I can combine further possibilities in the future. the first script compares user keywords from search mashines and the second replaces certain strings/paterns with others.
