I have a database with information of my users, lets say their date of
birth.
I want them to be able to go to my site, and login with a username and
password, after which they get to see what their date of birth is (according
to what's stored in the database).
I want to upload a textfile named "userinfo.txt" structured like:
<username>;<password>;<date of birth>, for example:
"johndoe";"johnpass";"1985-11-25"
"marydoe";"marypass";"1986-02-12"
What's the javascript to have a "username/password" box popup, and when a
valid name/pass was entered show the appropriate date of birth?
i have a widget which incllude html script, I am trying to send this widget to people that request it and allow them to use it in their own webpages....I am trying to figure out how to let the person enter information in the "form" and when they press the send button no screen pops up but the information is sent to a textfile in our public html directory....
I want to read a pre tag with xml. I am working client side. I have tried everything. The <title> tag gets lost with innerHTML(ok in FF only). I tried traversing the dom and putting in the tag names but the title tag is ignored. I am trying to syntax highlight this. Everything works if I do not use certain html tags. How do I get raw text from the pre? The text would come from one of two sources, a server or inputted into a textarea by the user. It is dynamically placed in the div tag and then processed.
I use Microsoft.XMLDOM load() method to load an XML file into memory and display some elements in the browser.
However it apparently locks the file, since I get this error message whenever a Visual Basic application concurrently tries to add an element to the same XML file:
The process cannot access the file because it is being used by another process.
I would like not to lock this file, but open it in read-only mode instead. In fact the browser simply needs to read its content, it doesn't need to modify it at all. As a consequence there is no reason to lock it.
At the same time, I need to access it from the VB process.
I have an external file, TestVar.js with a single line. NewsA("This is a test.","test.pdf","TEST")
Within my HTML I wish to use the array variables from TestVar.js, but can't seem to get them loaded for use. The following is what I have, but doesn't work. If I directly place the NewsA array in the script instead of trying to call it from the js it works just the way I want it, but I really need the external file. What am I doing wrong? Code:
I want to pass parameters thru URL. I know how to pass. I am finding problem in reading the parameters. here is the [URL]. how to to read these parameters from URL using java script?
I'm trying to read a cookie that I've set with php with javascript. The cookie is for storing the username when logging in to a site. If the cookie has been set I want the focus in the inline popup to target the password field so that the user doesn't have to tab down from the username field of the login form.
The php script stores the cookie perfectly: if (isset($_POST['remember'])){ $expire = time()+60*60*24*30; setcookie("login_username", $username, $expire); echo $_COOKIE['login_username']; } else { if (isset($_COOKIE['login_username']) || isset($_COOKIE['password'])){ $expire = time()-3600; setcookie("login_username", "", $expire); }}
The javascript: if (targetfocus == 'login_username'){ alert(readCookie('login_username')); if (readCookie('login_username') == 'username'){ targetfocus = 'password'; }} $("#"+targetfocus).focus(); ... function readCookie(name) { var cookieName = name + "="; var cookieArray = document.cookie.split(';'); for (var i = 0; i < cookieArray.length; i++){ var cookie = cookieArray[i]; while (cookie.charAt(0)==' '){ cookie = cookie.substring(1,cookie.length); }if (cookie.indexOf(cookieName) == 0){ return cookie.substring(cookieName.length,cookie.length); }return null; }}
But when trying to read the cookie in the javascript code I receive null when I put an alert to the code. Why won't the javascript find the cookie? Is it because I'm running the site localhost on my laptop? Does that have an effect on cookies?
While writing a look up for internet terms script for a site, I found the script will not read the second value in this array, I could make wl[1] a null value but would like to know what is happening if possible. All of the other elements seem to be ok!
function search(){ wl = new Array() wl[0]="applet - An Applet is a small application etc"; wl[1]="Bug? - Null but why"; wl[2]="cgi - CGI or Common Gateway Interface allows etc"; wl[3]="browser - A Browser is etc."; myWord=document.theForm.txtWord.value; myWord = myWord.toLowerCase(); for(c=0; c < wl.length; c++){ currentWord = wl[c].split(" "); alert(c + " MyWord " + myWord); alert(c + " Current " + currentWord[c]);// The alert box = 'Current -' when wl[1] is read. } }//end of function
Does anyone know how - or better yet - have a sample of how to extract information from a meta tag in an HTML document's head tag using Javascipt?
I have looked at the DOM with Firefox - but it seems so long. I'd be really interested in a better way. If someone has the javascript for walking through the DOM, that would be cool too. I havn't built it yet.
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].....
so I'm interested in knowing if there's a way through javascript, php whatever to be able to read the pages current URL. For example when the page loads and knows the difference between www.mySite.com/ and www.mySite.com/#aboutI'm trying to find if there's a way to use the '#about' as a variable for a particular script instead of just it being dummy text on the end of the URL.
I thought this would be simple for me to work out, but I can't seem to find reference to it. I'm flexable on how I call a URL, thus, if I have any one of the following:
How can I read the value to the right of the question mark?
I want to create a javascript function which reads the url, and, if the url was passed an arguement, it acts on it (namely, displays an error message)....
I'm having difficulty making a list (both drop down and radio button) read only; I am successful when I attempt to make a text field read only. Any suggestions on what java script I use to accomplish this?
If I have a link to a URL such as <a href="http://www.mysite.com/somecode.htm?5">Link1</a>, and if I include javascript in the somecode.htm file, is there a javascript command that I can use which will read the argument 5?
For that matter, is there anyway to send an argument to the javascript code of an html link you are calling. Server scripts are not an option for me.
For example, assuming that index.htm contains 50 links, I would like each link to point to the same html file, but I want that javascript code in that html file to execute something different depending on which link was clicked.
My only other alternative would be to create 50 similar html files which to me looks like amateur or bad coding.
var x =window.open('http://localhost/canvas.html','myokno') var w =x.width Permission denied to get property Window.width var w =x.innerWidth
Permission denied to get property Window.innerWidth why i can get properties of new created window??? The second problem is much more important: i want to get element which id is "canvas" and it is in new window so i do like this:
var canvas = myokno.document.getElementById('canvas') ReferenceError: myokno is not defined var canvas = x.document.getElementById('canvas') Permission denied to call method HTMLDocument.getElementById
so i start working on the problem and: var can = x.document can [object HTMLDocument] var can2 = can.getElementById('canvas') Permission denied to call method HTMLDocument.getElementById
I seem to remember being able to do this, but I can't seem to find out how I did it before...
Basically, I have styles defined by class in a stylesheet, and I need to read the "width" style. obj.currentStyle.width works just fine in IE, but Firefox doesn't recognize it.
document.defaultView.getComputedStyle(obj,null).ge tPropertyValue('width') gives me the actual width (just as obj.offsetWidth does), not the width style assigned by the stylesheet.
Because the elements are cells in a table row, the rendering of the table is causing the actual width to vary from the assigned width style. So, how can I get the assigned width style in Firefox (and other browsers)?
I need to make a javascript read a web directory from a remote site (ie "http://remotesite.com/images") (The remote die does not have an index.htm and does have directory listing enabled)
I have seen many samples but they all use frames or iframes, all I want is a method that you can say:
I am using IE5 and have a select-box with options that have different colors. Is there a way to read out the style attribute of the selectedIndex (here: color)? See simple demo script here under...
