I have a simple form that puts the info into cookies. I then need to check the entered name against the cookies, to see if they are the same. Currently there does not seem to be any cookies to check against, becuase my window.alert comes up blank. Please look over my code and see if you can spot the issue:
Code:
function getCookieData(labelName)
{
var labelLen = labelName.length;
var cookieData = document.cookie;
var cLen = cookieData.length;
I am having trouble with retrieving data from an xml file Here is the code I am using can anyone tell me where my problem lies?
[Code]...
as I am very new to Javascript and AJAX I am not very familiar with the process yet and I have not been able to get the xml loaded. Obviously I am declaring this all wrong as I receive the error that load is not a function of xmlDoc!
I want to store four cookies -- the name, the date the cookie was set, and the user's preferences for background color and foreground color. The name is set to John, the date set to 03-28-2005, the background color is set to red, and the foreground color is set to green.
Question 1: What is the entire cookie string (or name-value pair) returned when John visits the webpage?
Question 2: What code to use to extract the four values from the cookie string? The code should be written in a way that these values can be extracted wathever the order they appear in the cookie string.
Question 3: Why is it a good idea to store the date that the cookie is set? How is this information be useful?
According to W3Schools (which I've been warned to stay away from), browser cookies are just text files. This tells me that ALL cookie data is ALWAYS of string type. Is this true? Is it possible for a cookie to be an object, or an int, or anything other than string?
when this page loads i want the name input type field to automatically display the resuld of my cookie. if this page does not have a cookie set yet it shouldn't put anything in the field. when i use the script below, the cookies get set fine, and i can alert them when the page comes in, but the value will not show in the input field. when alerting alert window.document.cart3form.name.value) the returned value is undefined. anybody know how to get the unput field to enter right?
form name=cart3form script language=JavaScript type=text/JavaScript
alert(getCookie('name2')); // shows correct value of name2
I am developing an application which allows a web site visitor to email a page to a friend using the PHP mail() function.
What I would like to do is dynmaically extract the H1 from each page using JS and store this as a PHP session named title. Can I get this info using JS?
I'm slowly discovering the world of JavaScript, so I'm not sure I'm attacking this problem in the right manner, thus if I'm in the wrong newsgroup, my apologies.
What I'm trying to do is extract some news items from a web site. To do this, I'm using Microsoft Word VBA and using the following bit of script:
I found this little script for extracting parameters from a url but wondered what the shortest and most efficient way to do it would be, like the following or via regexp?
function getParameter(paramName) { var currentUrl = window.location.search var strBegin = currentUrl.indexOf(paramName) + (paramName.length+1) var strEnd = currentUrl.indexOf("&",strBegin)
if (strEnd==-1) strEnd = currentUrl.length return currentUrl.substring(strBegin,strEnd) }
What will be the best way to extract dynamically changing information from a web page that holds XML?I have to extract some data from multiple web pages.These sites contain XML code that dynamically reloads (and changes) parts of the page.Since only small parts get a refresh (perhaps 200 bytes every 5 seconds) it wouldn't be efficient (and also might lead to negative reactions from the server) to reload the whole page (about 40k) every time.How could I best determine these updated contents and send them to the program that further processes them?I am familiar with several programming languages but unfortunately have very little knowledge of internet programming.
I'm trying to get some average rgb values from an image in one canvas object and apply them via fillstyle to a rectangle in another canvas object.I have a dropdown that loads an image onChange()="ChangeBaseWood()" into a canvas object. The second canvas object is to be filled with an average color based on the content of the first canvas onClick="GetBaseColor()". For simplicity I've replaced the for loop with just the values of pixel 0,0. Where I think I am assigning the rgb values, the error console keeps reporting that var sample is undefined at the line "var redpart = sample[0].
function ChangeBaseWood(){ var dropdown = document.getElementById('woodvalue'); var woodcanvas = document.getElementById('basewood');[code]....
I've tried various things to assign the redpart,grnpart and blupart but I'm missing something basic.
I have a bit of a problem and as my javascript is a rather poor I'm struggling to come up with a solution. Basically I need to split the variable "#country" into two parts and call the second half as the "this" value for '#int-dc'. Using '+' as the start point end ending at the end of the string.
For instance 'this' returns 12+44 I want to split it to "12" and "+44" the latter (+44) replacing 'this' in the code below.
I'm trying to write code that will extract from an XML file and then display the results. Keep getting a syntax error.
HTML: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html>[code]....
My intention was to access all of the tags (name, genre, and hitsong) in the XML file. Thought that var musicianInfo = xmlDoc.getElementsByTagName("*"); would do that. Then, loop through each tag and display the result.
This randomising function is like a coin toss, it gives a numerical result and displays it:
function Ran() { var c = Math.random(); return (c < 0.5) ? [0, show0()] : 1, show1()]; }
I want to extract the numerical outcome, 0 or 1, from this and from two other similar functions, sum them, and then run more functions based on the possible sums.
What is the syntax for getting to the numbers? something like
I am trying to extract the domain name from a url using javascript but having some problems.
This is what I have:
Code: var publisherName = document.domain; if(publisherName.indexOf('www')){ publisherName = document.domain.substr(3,document.domain.length); }
But it is not working and I am not sure how to rid of the extension Basically, this is what I want: Whether the location being sub domain or not it need to get from somthing similar to[URL]...
I'm loading an xml data file and then trying to take a particular node and add it, as html, to an element on my page using inner HTML. The xml is like what is below, with the . Code:
I want to parse data from tables in webpages , there are no problems when I parse regular HTML tables, but it seems to be impossible to get any data from dynamic pages that update themself automatically.how to extract data from dynamic web pages? My goal is to read webpages with an application written in java, parse the page and clean the data and store it in a database.
i have two links,i left the second one alone so you can see what result i want. but the first link is where i am attempting to remove the inline event handler (onclick) but i want the same result.
I'm looking for a regular expression that will match everything in this string before 546 so that I can replace it with an empty string and just be left with 546. The string could be of any length and contain any number of hyphens.
