I have a web site that is in two languages, English and French. now i do not know java-script, I created a code for showing different pictures using javascript depending on which language u want to use.
So if you are on the www.my-site.com/en/ you will see En_pic_ pictures same goes for the opposite.
/*These are the Popup images for the English and French portal */
var url1 = 'http://www.my-site.com/fr/';
var url2 = 'http://www.my-site.com/en/';
MagnifImage.setup(
if (window.location = 'url2'){
"En_pic_1", "/images/1.png","",
"En_pic_2", "/img/content/tracking_instructions/2.png", "",
"En_pic_3", "/img/content/tracking_instructions/3.png", "",
"En_pic_4", "/img/content/tracking_instructions/4.png", "",
}else{
"Fr_pic_1", "/img/content/tracking_instructions/1_fr.png", "",
"Fr_pic_2", "/images/mon-compte.png","",
"Fr_pic_3", "/img/content/tracking_instructions/3_fr.png","",
"Fr_pic_4", "/img/content/tracking_instructions/4_fr.png",""
}
);
Everything works but if I am on the other language page I get an alert box saying there is no Fr_pic_1 or En_pic_1.(depending on the current page I am in) The code I found to accomplish this as follows:
if( !(objRef.trigElem=document.getElementById( idParts[0] )) )
alert("There is no element with the ID:'"+idParts[0]+"'\n\nCase must match exactly\n\nElements must be located ABOVE the script initialisation.");
else
{
if(objRef.trigElem.parentNode && objRef.trigElem.parentNode.tagName=='A')
objRef.trigElem=objRef.trigElem.parentNode;
objRef.classId=idParts[1] || "MagnifImage" ;
objRef.imgObj=new Image();
objRef.imgObj.imgIndex=i;
objRef.imgObj.hasLoaded=0;
its a code I found at http://scripterlative.com?magnifimage
Please help....
You need to fix multiple things:
You must use == or === for comparison. A single = is assignment, not comparison.
You must compare to the variable name url2, not a quoted string 'url2'.
You must fix the way you pass the alternate parameters to your function MagnifImage.setup().
I switched to using window.location.href because window.location is an object and I find it better to use the actual attribute of that object you want rather than rely on an implicit conversion.
Change your code to this:
/*These are the Popup images for the English and French portal */
var url1 = 'http://www.my-site.com/fr/';
var url2 = 'http://www.my-site.com/en/';
if (window.location.href == url2) {
MagnifImage.setup("En_pic_1", "/images/1.png","",
"En_pic_2", "/img/content/tracking_instructions/2.png", "",
"En_pic_3", "/img/content/tracking_instructions/3.png", "",
"En_pic_4", "/img/content/tracking_instructions/4.png", "");
} else {
MagnifImage.setup("Fr_pic_1", "/img/content/tracking_instructions/1_fr.png", "",
"Fr_pic_2", "/images/mon-compte.png","",
"Fr_pic_3", "/img/content/tracking_instructions/3_fr.png","",
"Fr_pic_4", "/img/content/tracking_instructions/4_fr.png","");
}
Your code was likely causing many errors and thus not executing at all. You should learn how to look for javascript errors. Every browser has an error console that will show you javascript parsing or executing errors. Many browsers now have a built-in debugger than has a console in it that will also show you such information and allow you to see the exact source line causing the error. I use Chrome which has a built-in debugger which will do this. Firefox has a free add-on called Firebug that will do this.

I would like to change (or add if it doesn't exist) to a PDF file with multiple pages the setting that will force the PDF to be opened in two page mode (PageLayout : TwoPageLeft for example).
I tried with that kind of JavaScript (given with Enfocus FullSwitch as example) :
if(($error == null) && ($doc != null))
{
try
{
$outfile = $outfolder + '/' + $filename + ".pdf";
$doc.layout = "TwoPageLeft";
$doc.saveAs( {cPath : $outfile, bCopy : true});
$outfiles.push($outfile);
}
catch(theError)
{
$error = theError;
$doc.closeDoc( {bNoSave : true} );
}
}
But it doesn't work as I would like (it will be opened with Acrobat Pro and saved as a new file without including the setting about the layout).
Does anyone can help me to correct that code to let JS open the PDF file, set the layout inside the PDF datas and save it out?
The readable information inside the PDF file should looks like this:
PageLayout/TwoPageLeft/Type/Catalog/ViewerPreferences
For information, I'm using FullSwitch (Enfocus) to handle files in a workflow, with Acrobat Pro, and at this time, it's only saving the file without adding the setting.
I can't find myself the answer over all the Web I searched recently, so I ask…
Thanks in advance!
I think you copied the "this.layout = ..." line out of the Acrobat JavaScript reference documentation, correct?
When you write a JavaScript for Switch to execute (or rather for Switch to instruct Acrobat to execute for you), you should use the "$doc" variable to refer to the document Switch is processing.
So try changing the line:
$this.layout = "TwoColumnLeft";
to
$doc.layout = "TwoColumnLeft";
As you say the rest of the code works and the document is saved without errors I assume the rest of your code is correct. The change proposed here will make the adjustment in the document you're looking for.
I am building a chrome extension for reddit.com and I am using page action for that. Now I want page_action icon to be visible only for a specific url format i.e.
http://www.reddit.com [allowed]
http://www.reddit.com/r/* [allowed]
http://www.reddit.com/r/books/comments/* [not allowed]
So, as I have mentioned above that I don't want my extension page action icon to be visible for the 3rd case involving comments url of redddit .
Currently I am using the below code in my background.js to achieve this:
function check(tab_id, data, tab){
if(tab.url.indexOf("reddit.com") > -1 && tab.url.indexOf("/comments/") == -1){
chrome.pageAction.show(tab_id);
}
};
chrome.tabs.onUpdated.addListener(check);
I have also added the below line in my manifest.json to disable the extension on the comment page
"exclude_matches": ["http://www.reddit.com/r/*/comments/*"],
So, my question is this the correct/ideal way to disable & hide an extension from a specific page/url?
Why not Zoidb- I mean, Regular Expressions?
var displayPageAction = function (tabId, changeInfo, tab) {
var regex = new RegExp(/.../); //Your regex goes here
var match = regex.exec(tab.url);
// We only display the Page Action if we are inside a tab that matches
if(match && changeInfo.status == 'complete') {
chrome.pageAction.show(tabId);
}
};
chrome.tabs.onUpdated.addListener(displayPageAction);
About the approach, I think using the onUpdated.addListener is the correct approach. As a good practice, try to show your page Action only when the tab has been loaded, unless your application requirements specify otherwise.
You can use this tool in order to generate your regular expression, and if you need help, feel free to ask again and we will help you assemble the regular expression you need.
i'm writing an greasemonkey script for somebody else. he is a moderator and i am not. and the script will help him do some moderating things.
now the script works for me. as far as it can work for me.(as i am not a mod)
but even those things that work for me are not working for him..
i checked his version of greasemonkey plugin and firefox and he is up to date.
only thing that's really different is that i'm on a mac and he is pc, but i wouldn't think that would be any problem.
this is one of the functions that is not working for him. he does gets the first and third GM_log message. but not the second one ("got some(1) ..").
kmmh.trackNames = function(){
GM_log("starting to get names from the first "+kmmh.topAmount+" page(s) from leaderboard.");
kmmh.leaderboardlist = [];
for (var p=1; p<=(kmmh.topAmount); p++){
var page = "http://www.somegamesite.com/leaderboard?page="+ p;
var boardHTML = "";
dojo.xhrGet({
url: page,
sync: true,
load: function(response){
boardHTML = response;
GM_log("got some (1) => "+boardHTML.length);
},
handleAs: "text"
});
GM_log("got some (2) => "+boardHTML.length);
//create dummy div and place leaderboard html in there
var dummy = dojo.create('div', { innerHTML: boardHTML });
//search through it
var searchN = dojo.query('.notcurrent', dummy).forEach(function(node,index){
if(index >= 10){
kmmh.leaderboardlist.push(node.textContent); // add names to array
}
});
}
GM_log("all names from "+ kmmh.topAmount +" page(s) of leaderboard ==> "+ kmmh.leaderboardlist);
does anyone have any idea what could be causing this ??
EDIT: i know i had to write according to what he would see on his mod screen. so i asked him to copy paste source of pages and so on. and besides that, this part of the script is not depending on being a mod or not.
i got everything else working for him. just this function still doesn't on neither of his pc's.
EDIT2 (changed question): OK. so after some more trial and error, i got it to work, but it's still weird.
when i removed the www-part of the url thats being use in the dojo.xhrGet() i got the finally the same error he got. so i had him add www to his and now it works.
the odd thing is he now uses a script with the url containing "www" and i'm using a script with an url without "www"...
so for me:
var page = "http://somegamesite.com/leaderboard?page="+ p;
and for him:
var page = "http://www.somegamesite.com/leaderboard?page="+ p;
Why don't you have him try logging into an account that is not a moderator account so that you eliminate one of your variables from your problem space.
It's possible that the DOM of the page is different for a moderator than for a regular user. If you're making assumptions about the page as a regular user that are not true as a moderator, that could cause problems.
I suspect that to fix it, you may need access to a moderator account so you can more easily replicate the behavior.
ooops. it seemed that the url of this gamesite is accessible as www.gamesite.com as well as gamesite.com (without the www.part). this caused the problem.
sorry to bother you'all.
i go hide in shame now...
Is it possible to get last page URL from the history object? I've come accross history.previous but that's either undefined or protected from what I've seen.
Not from the history object, but from document.referrer. If you want to get the last actual page visited, there is no cross-browser way without making a separate case based on support for each property.
You cant get to history in any browser. That would be a serious security violation since that would mean that anyone can snoop around the history of their users.
You might be able to write a Browser Helper Object for IE and other browsers that give you access to that. (Similar to the google toolbar et al). But that will require the users to allow that application to run on their machine.
There are some nasty ways you can get to some history using some "not-so-nice" ways but I would not recommend them. Look up this link.
Of course, as people have said, its not possible. However what I've done in order to get around this limitation is just to store every page loaded into localStorage so you can create your own history ...
function writeMyBrowserHistory(historyLength=3) {
// Store last historyLength page paths for use in other pages
var pagesArr = localStorage.myPageHistory
if (pagesArr===null) {
pagesArr = [];
} else {
pagesArr = JSON.parse(localStorage.myPageHistory);
pagesArr.push(window.location.pathname) // can use whichever part, but full url needs encoding
}
if (pagesArr.length>historyLength) {
// truncate the array
pagesArr = pagesArr.slice(pagesArr.length-historyLength,pagesArr.length)
}
// store it back
localStorage.myPageHistory = JSON.stringify(pagesArr);
// optional debug
console.log(`my page history = ${pagesArr}`)
}
function getLastMyBrowserHistoryUrl() {
var pagesArr = localStorage.myPageHistory
var url = ""
if (pagesArr!==null) {
pagesArr = JSON.parse(localStorage.myPageHistory);
// pop off the most recent url
url = pagesArr.pop()
}
return url
}
So then on a js in every page call
writeMyBrowserHistory()
When you wanna figure out the last page call
var lastPageUrl = getLastMyBrowserHistoryUrl()
Note: localStorage stores strings only hence the JSON.
Let me know if I have any bugs in the code as its been beautified from the original.
I am new to Javascript and Web development and I have a question regarding the document.location.href.
I am using a cookie for storing the language the user prefers and then load the english or the swedish version depending on the language.
The default language in the beginning is the same as the browser's language, and my index.jsp is the swedish one. The first time everything works fine. The problem is when the cookie exists already. The basic code is:
if (language!=null && language!=""){
if (language=="en-US" || language=="en-us")
document.location.href = "en/index.jsp";
}
else{
//Explorer
if (navigator.userLanguage)
language = navigator.userLanguage;
//other browsers
else
language = (navigator.language) ? navigator.language : navigator.userLanguage;
if (language!=null && language!=""){
setCookie('language', language, 365, '/', 'onCheck');
if (language=="en-US" || language=="en-us")
document.location.href = "en/index.jsp";
else if(language=="sv")
document.location.href="index.jsp";
}
}
When the cookie exists we enter the first "if", and there, if the language is swedish it opens the default blabla/index.jsp page. When the language is set to engish it should open the blabla/en/index.jsp but instead it opens the blabla/en/en/index.jsp which of course is wrong.
Does anyone know what I am doing wrong??
Thanks
Add a slash in the beginning, ie:
document.location.href = "/en/index.jsp";
Currently, you are redirecting using a relative path when you want to redirect using an absolute path. Slashes in the beginning always means absolute.
If you've ever used a Unix machine, you'd know that /etc/123/abc is a path that goes from the root, whereas etc/123/abc/ would be a relative path, building on the current directory. The same is true here.
If this is a commercial site and you care about your Google ranking then you should be cautious about using JavaScript redirects.
Search engine crawlers cannot follow these kinds of redirects. It would be better to process it on the server side and perform a true 301 redirect.
Also you should give some way to manually change this by clicking a button in your UI.
This code doesn't make any sense to me:
//Explorer
if (navigator.userLanguage)
language = navigator.userLanguage;
//other browsers
else
language = (navigator.language) ? navigator.language : navigator.userLanguage;
It seems to check if .userLanguage is populated and if it isnt it checks if .language is populated and if that isn't it uses .userLanguage which by this point has already been deemed as undefined.
I would refactor the code something like this:
if (IsCookieSet()) {
if (IsCookieLanguage("en-US")) {
document.location.href = "en/index.jsp";
}
}
else {
language = navigator.userLanguage ? navigator.userLanguage : navigator.language;
if (!IsCookieSet()){
setCookie('language', language, 365, '/', 'onCheck');
if (IsCookieLanguage("en-US")) {
document.location.href = "en/index.jsp";
}
else if(IsCookieLanguage("sv"))
{
document.location.href="index.jsp";
}
}
}
function IsCookieSet()
{
return language!=null && language!="";
}
function IsCookieLanguage(lang)
{
return language.toLowerCase() == lang.toLowerCase();
}
Well that code is a bit cleaner but it still doesn't make much sense because you haven't included all of your code - ie the bit that retrieves the cookie.
It seems you are already on a page in blabla/en/ then. Check that out.
