JavaScript - How To Secure Api Keys In Javascript?
Hello,
I am using some api solutions in my javascript. But, those api solutions require api keys as parameters. In this case, users can see my api keys by displaying page source? What is a true approach and solution of course? Thanks Similar TutorialsI have a randomly generated Language file that corresponds to keys, the reason Ii say randomly generated is that the letter to key values used are not standard assignments. It seems the language coding is DEC in sets of 3 values by 5 .i.e. "248 036 034 036 248" = A "036 084 084 084 120" = a (See attached : ENGLISH-1.txt) How would I assign these values to a sentence lets say: All great : 248 036 034 036 248 ll gre 036 084 084 084 120 t but convert all characters to their correspondnig sets of 5 ? This then needs to get sent to a database where it is interpreted into sets of Binary to turn on and off LEDs' ... I have never worked with Javascript or LED's before, so any help is so appreciated. How to use the shortcut keys in jvascript? Can someone illustrate it to me with an example? Such as suppose on clicking the Ctrl+alt key,i want to display a prompt dialog box........How to do this? Need some urgent help..... thank you in advance Disable Arrow Keys I am creating an online flash gaming site, Aaron's Game Zone: http://azzaboi.weebly.com Some of the games on it use the arrow keys, however IE also uses them to scroll the page. I am learning JavaScript and am trying to write some script to pervent the page scrolling up and down while playing a game. For example... Guardian Rock uses the arrow keys to slide around, at the same time the page scrolls. http://azzaboi.weebly.com/guardianrock.html Here is the script I've tried to write to pervent the scrolling: Code: <script type="text/javascript">
function KeyPressHappened(e){
if (!e) e=window.event;
var key=e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
if(key == 37 || key == 38 || key == 39 || key == 40)
{
e.preventDefault();
return false;
}
return true;
}
document.onkeypress = KeyPressHappened;
</script>
There's a bug in it or it's not correct, no error message given, could anyone point out the mistake please? I need to disable some keys from their default behaviour in Google Chrome on Windows with javascript. The script below works for most keys but not for F10, left Windows key, right Windows key, NumLock and left Alt. (which are the keys I need to disable) Code: <script type="text/javascript">
addEventListener("keydown", function (event) {
if(KeyID == 121 KeyID == 91 || KeyID == 92 || KeyID == 144|| KeyID == 18 ){
event.preventDefault();
}
}, true);
</script>
I have also without luck tried event.stopPropagation () - event.cancelBubble = true - return false og void(). I would like to know if their is a solution or it simply isn't possible to disable the mentioned keys. hi everybody; i'm using this code to trigger functions with left and right arrow keys.. but they work even if the arrow keys pressed in input boxes.. is there any way to prevent this code to work when user presses the arrow keys in input boxes? Code: document.onkeydown = function(evt) {
evt = evt || window.event;
switch (evt.keyCode) {
case 37:
geri();
gostergeyaz();
break;
case 39:
ileri();
gostergeyaz();
break;
}
};
Hi all, I was under the impression that I and object/associative array could have other objects as the keys for properties. That is, I should be able to set myObject[anotherObject] = 1. However, while this seems to work at first glance, any new object I set as a property key overwrites the first one. Here is the result of me testing in my Chrome console: Code: > var obj1 = new Object();
> var obj1.someProperty = "test"
"test"
> var obj2 = new Object();
> obj2.someOtherProperty = "test2"
"test2"
> obj1 == obj2
false
> obj1 === obj2 // the two objects I created are definitely not the same
false
> x = {}
> x[obj1] = 0 // set the two objs as property keys on x
0
> x[obj2] = 1
1
> x[obj1]
1 // blargh! x.obj2 overwrote x.obj1!
Any idea if this is possible, and if I'm just messing up with something dumb? On http://kisa.ca/cc/ I'm using JQuery's .keydown() to grab arrow keys. http://pastie.org/938572 But my friends using Linux are unable to use arrows to play the game: http://alteeve.com/files/cc.png Halp? I have a search box on my website, that gets users from my database using php. And uses Javascript to display suggestions as the users type. What I'd like to be able to is to use the arrows to toggle down through the different suggestions. Any ideas how I would go about doing this? Here's the javascript part of the code: Code: function createObject() {
var request_type;
var browser = navigator.appName;
if(browser == "Microsoft Internet Explorer"){
request_type = new ActiveXObject("Microsoft.XMLHTTP");
}else{
request_type = new XMLHttpRequest();
}
return request_type;
}
var http = createObject();
/* -------------------------- */
/* SEARCH */
/* -------------------------- */
function autosuggest() {
q = document.getElementById('search-q').value;
// Set te random number to add to URL request
nocache = Math.random();
http.open('get', 'lib/search.php?q='+q+'&nocache = '+nocache);
http.onreadystatechange = autosuggestReply;
http.send(null);
}
function autosuggestReply() {
if(http.readyState == 4){
var response = http.responseText;
e = document.getElementById('results');
if(response!=""){
e.innerHTML=response;
e.style.display="block";
} else {
e.style.display="none";
}
}
}
I am trying to assign the left and right arrows, but I cannot get the code to work. It would be great to get some help--I am a newbie to coding. <html> <head> <script language="javascript" type="text/javascript"> document.onkeydown=function(e) { var thelink if (e.keyCode==37) thelink='prevlink' else if (e.keyCode==39) thelink='nextlink' else return document.location.href=document.getElementById(thelink).href} </script> </head> <body> <a href="#" onkeydown="return previous(this)" id="prevlink">PREVIOUS</a><br /> <br /> <a href="#" onkeydown="return next(this)" id="nextlink">NEXT</a> </body> </html> I have three buttons on a typical page (sample page: http://jimoberst.com/paintings/p18.html). One goes to the previous page, one to the next, and one up a level. Can I link these buttons to 3 arrow keys to simplify navigation for the user? I thought this would be a common task, but I cannot find any canned code on the web to do it. I can code simple html, but don't know javascript. Thanks!
Hello, Into an external js file, I'm trying to use the facebook graph api to read values of "shares" and "comments" and import them into js variables. As example, using http://graph.facebook.com/?id=http://www.google.com in the browser, I get the following response: Code: {
"id": "http://www.google.com",
"shares": 3208837,
"comments": 2
}
In my js code, I need something like: var val_shares=xx; var val_comments=xx; Here's the code I'm using to (try) do it: Code: function getNewHTTPObject()
{
var xmlhttp;
/** Special IE only code ... */
/*@cc_on
@if (@_jscript_version >= 5)
try
{
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (E)
{
xmlhttp = false;
}
}
@else
xmlhttp = false;
@end @*/
/** Every other browser on the planet */
if (!xmlhttp && typeof XMLHttpRequest != 'undefined')
{
try
{
xmlhttp = new XMLHttpRequest();
}
catch (e)
{
xmlhttp = false;
}
}
return xmlhttp;
}
var xmlHttp = getNewHTTPObject();
function getDynamicData()
{
var url = "http://graph.facebook.com/?id=http://www.google.com";
xmlHttp.open('GET', url, true);
xmlHttp.onreadystatechange = callbackFunction;
xmlHttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xmlHttp.send(null);
}
var syndLinkRequest = getNewHTTPObject();
function callbackFunction()
{
if (syndLinkRequest.readyState != 4)
return;
var result = xmlHttp.responseText;
}
into the HTML I call getDynamicData() at <body onload=getDynamicData()>... Using Firefox in console mode, I see that the results arrive at this point of code: Code: xmlHttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xmlHttp.send(null);
But I do not know (or understand) how and where to get those value to associate them to a js variable. I understood I will need to use json to achieve this but I don't know where to start. In addition, I can't use jQuery or php to do it. After 2 days of searches, I'm about to give up. Does anyone have an idea how to do or where I can find a concrete sample to show me the right way ? Thanks a lot. Gino I found strange for the following code: Code: var allextRules = Ext.util.CSS.getRules();
Object.keys(allextRules).forEach(function(key) {
var keyname = key;
if(keyname.indexOf("js") != -1){
Ext.util.CSS.removeStyleSheet(keyname);
console.log(keyname + " Removed");
}
});
When the above work is tested in other browser (say - Google Chrome), there is no error. However, when tested in IE 9, there is error as follows: Code: SCRIPT438: Object doesn't support property or method 'keys' According to this article (https://developer.mozilla.org/en/Jav...ts/Object/keys), the Object.keys is supported by IE. Have I miss out something? I am making an app which will later on allow developers to make plugins for the user to add to his account, but I am starting to think this kind of thing is a security risk because my app is mostly based on ajax and for instance if my app asks the server to delete a file the server accepts, but how will it know if that request was sent by my app and not by a plugin? The plugins reside in iframes which javascript allows to send ajax requests to the domain of the page. I would really appreciate any help. thanks. Is there any type of script or plugin out that has a secure, DropBox-like interface? I wanted clients to have a username and password, and that username and password to be tied to a mysql db of sorts that allows them access to their specific FTP space without them knowing the actual server info.
HI I am trying to get rid of this warning over and over. My pages are located in directory WEBSERVER\APPLICATIONS\WC Master pages in WEBSERVER\APPLICATIONS CSS and Javsasripts are in WEBSERVER and in css I have background:url(Images/GlowTab.png) no-repeat right top; Dont know even though the image gets accessed by Https. why it is still giving that warning. Hello! I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please? Thanks so much for your help. I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael Hi Guys, I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled! I create the following code but it did not work <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>New Web Project</title> <script language="JavaScript" type=""> function changeColor(){ document.bgColor = "Gray"; } </script> </head> <body> <script language="JavaScript" type="text/javascript"> var person = ""; person = prompt('What is Your Name:'); if (person == "Foo") { document.write("<h1 />Welcome " + person); document.bgColor = "Yellow"; } else { document.write("<h1 />Access Denied!!!!"); document.bgColor = "Red"; document.getElementById("gree").disabled = true; } </script> <div> <p/><input id="gree" type="button" value="Gray " onClick="changeColor();"> </div> </body> </html> as you can see I used the: document.getElementById("gree").disabled = true; but it did not work , could you please give an idea how I can solve this problem?
