Develop Reference

Adding a Parameter to Url with javascript

I am trying to add the parameter "referer=" to my url corresponding to the trafic referer of a new session.
I used some of the code from this topic... but it keeps reloading the page in a loop... then the url is like :
https://example.com?refere=facebookreferer=facebookreferer=facebook
Note:
I have been using this solution 1 :
function addOrUpdateUrlParam(name, value)
{
var ref = document.referrer;
var refsplit = ref.split(".")[1];
var href = window.location.href;
var regex = new RegExp("[&\\?]" + name + "=");
if(regex.test(href))
{
regex = new RegExp("([&\\?])" + name + "=\\d+");
{
else
{
if(href.indexOf("?") > -1)
window.location.href = href + "&" + name + "=" + value;
else
window.location.href = href + "?" + name + "=" + value;
}
if (refsplit != "example") {
return addOrUpdateUrlParam("referer", refsplit);
}
}
And this solution 2:
function () {
var ref = document.referrer;
var refsplit = ref.split(".")[1];
if (refsplit != "example") {
return location.search += "referer=" + refsplit;
}
}
Edit 1:
Thanks to Prasanth I improved the code to :
function () {
var ref = document.referrer;
var refsplit = ref.split(".")[1];
var currentUrl = location.href;
var url1 = currentUrl += "?referer="+refsplit;
var url2 = currentUrl += "&referer="+refsplit;
if(currentUrl.indexOf("?") < 0) {
return window.location = url1;
} else {
return window.location = url2;
}
}
However, it is returning both conditions :
https://example.com/?referer=facebook&referer=facebook
Edit 2:
So after many attempts, I achieved it by working with the parameters of the url (location.search) instead of the full url (location.href) :
function addRefererParam () {
var ref = document.referrer; //Get Referrer
var refDomain = ref.match(/[^(?:http:\/\/|www\.|https:\/\/)]([^\/]+)/i)[0]; //Extract Referrer Domain name for better readability
var params = location.search; //Get Url parameters
if (refDomain.match(/mydomain|null|undefined/i)) { //check if domain not null or own domain.
return params ;
} else {
return params += "utm_source=" + refDomain; //create new query string with referrer domain
}
}
However, it is no making a persistent query string through browsing... how can I make the new parameters persistent ?

Obtain the url of the current window and after the domain name just concat your url with &referer=value.
var currentUrl = location.href;
var paramsInUrl = currentUrl.split('&');
var flag = true;
for(var i in paramsInUrl)
{
if(!paramsInUrl[i].includes('referer=')
{
continue;
}
else
{
flag = false;
break;
}
}
if(flag)
{
currentUrl += '&referer='+value;
window.location = currentUrl;
}

For what it's worth (because the more generic question of just how to do this generally is what lead me to this post), I've made a 178 byte helper function that takes in an object of the query parameters you want to add to a url for a GET request (in similar format for how you might add headers to a request) and made an npm package for it here: https://www.npmjs.com/package/add-query-params-to-url
Hopefully this is helpful to some.

How can I show with PhantomJS the url of the processed page in the generated PDF?

My goal was to generate a PDF from every page included in the sitemap of a website created with Rails. I'm using PhantomJS to get it. I'm quite new in this field, but I could do it, but when I was finished, I realized that it would be usable also to see at the beginning of every PDF the url of the page from which the PDF was generated, so I can browse quicker to the page (the site has over hundred pages).
Here is the Javascript:
// Render Sitemap to file
var RenderUrlsToFile, arrayOfUrls, system;
system = require("system");
/*
Render given urls
#param array of URLs to render
#param callbackPerUrl Function called after finishing each URL, including the last URL
#param callbackFinal Function called after finishing everything
*/
var getFileNumber = function(urlIndex) {
if (urlIndex <10) {
return "00" + urlIndex;
} else {
if (urlIndex <100) {
return "0" + urlIndex;
} else {
return urlIndex;
}
}
};
RenderUrlsToFile = function(urls, callbackPerUrl, callbackFinal) {
var getFilename, next, page, retrieve, urlIndex, webpage;
urlIndex = 0;
webpage = require("webpage");
page = null;
getFilename = function() {
return "rendermulti-" + getFileNumber(urlIndex) + ".pdf";
};
next = function(status, url, file) {
page.close();
callbackPerUrl(status, url, file);
return retrieve();
};
retrieve = function() {
var url;
if (urls.length > 0) {
url = urls.shift();
urlIndex++;
page = webpage.create();
page.viewportSize = {
width: 1920,
height: 1880
};
page.settings.userAgent = "Phantom.js bot";
return page.open(url, function(status) {
var file;
file = getFilename();
if (status === "success") {
return window.setTimeout((function() {
// !!!!!!!!!!!!! Doesn't work !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
page.evaluate(function() {
var x = document.getElementById("logoAndNavigation");
var newP = document.createElement("P")
var textnode = window.location.protocol + "//" + window.location.host + "/" + window.location.pathname;
newP.appendChild(textnode)
x.insertBefore(newP, x.childNodes[0]);
});
// !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
page.render("tempPdfs/" + file);
return next(status, url, file);
}), 200);
} else {
return next(status, url, file);
}
});
} else {
return callbackFinal();
}
};
return retrieve();
};
// This makes an array with all the urls inside the sitemap
var arrayOfUrls = [''];
var page = require('webpage').create();
page.open('http://localhost:3000/sitemap.xml', function() {
var content = page.content;
parser = new DOMParser();
xmlDoc = parser.parseFromString(content,'text/xml');
var loc = xmlDoc.getElementsByTagName('loc');
for(var i=0; i < loc.length; i++)
{
var url=loc[i].textContent;
arrayOfUrls.push(url);
}
});
RenderUrlsToFile(arrayOfUrls, (function(status, url, file) {
if (status !== "success") {
return console.log("Unable to render '" + url + "'");
} else {
return console.log("Rendered '" + url + "' at '" + file + "'");
}
}), function() {
return phantom.exit();
});
I tried to solve the issue with the urls, with the code framed with the comment
// !!!!!!!!!!!!! Doesn't work !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I wanted to show the url inside an element of the page, that has the id #logoAndNavigation, but I get this error:
NOT_FOUND_ERR: DOM Exception 8: An attempt was made to reference a Node in a context where it does not exist.
If I use only a string like "hello" inside the variable textnode, it works, but not if I try to use the url of the page.
Can anyone please help me?
Thank you in advance!

appendChild expects a node not a string. You probably mean to use
var x = document.getElementById("logoAndNavigation");
var newP = document.createElement("p"); // small p
var textnode = window.location.protocol + "//" + window.location.host + "/" + window.location.pathname;
newP.innerHTML = textnode; // this
x.insertBefore(newP, x.childNodes[0]);
You can also use the example of printheaderfooter.js to add the URL directly to the header or footer.

omit certain pages from history cookie

I am using this script to store the user's history to a cookie for the last 10 pages accessed. So far I've got the script displaying the cookie data using the document.title, and url in a list.
My question is what would be the simplest way to add a page skip feature, that would let me omit certain pages from being added to the history cookie? Everything I've tried hasn't worked, as it's a little bit outside of my knowledge.
Thanks for your time and help.
JS:
(function($){
var history;
function getHistory() {
var tmp = $.cookie("history");
if (tmp===undefined || tmp===null) tmp = "";
if ($.trim(tmp)=="") tmp = [];
else tmp = tmp.split("||");
history = [];
$.each(tmp, function(){
var split = this.split("|");
history.push({
title: split[0],
url: split[1]
});
});
}
function saveHistory() {
var tmp = [];
$.each(history, function(){
tmp.push(this.title+"|"+this.url);
});
$.cookie("history",tmp.join("||"),{ expires: 60, path: "/" });
}
function addToHistory(title,url) {
var newHistory = []
$.each(history, function(){
if (this.url!=url) newHistory.push(this);
});
history = newHistory;
if (history.length>=10) {
history.shift();
}
history.push({
title: title,
url: url
});
saveHistory();
writeHistory();
}
function writeHistory() {
var list = $("<ul />");
$.each(history, function() {
var element = $("<li />");
var link = $("<a />");
link.attr("href",this.url);
link.text(this.title);
element.append(link);
list.append(element);
});
$("#history").empty().append(list);
}
$(document).ready(function(){
getHistory();
var url = document.location.href;
var split = url.split("#");
var title;
if (split.length > 1) {
title = $("#"+split[1]).text();
} else {
title = document.title;
}
if (title===undefined || title===null || $.trim(title)=="") title = url;
addToHistory(title,url);
url = split[0];
$("a[href^='#']").click(function(){
var link = $(this);
var href = link.attr("href");
var linkUrl = url+href;
var title = $(href).text();
if (title===undefined || title===null || $.trim(title)==="") title = linkUrl;
addToHistory(title,linkUrl);
});
});
})(jQuery);
HTML:
<div id="history"></div>

several ways you could approach this... You could keep an Array of urls not to save, or you could put something in the page that would let the script know not to save that page?...
function saveHistory(){
if ($('.no-save-history')) return false;
/*...*/
}
HTML:
< div id="history" class="no-save-history">

Owner dropdown not filtering Story cardboard

I built a custom cardboard mashup to display all user stories that are in a "committed" iteration and beloning to the current project, or any child project. This much works well. I then added an Owner dropdown box (limited to Team Members only), to filter the stories on the cardboard. The resulting query value appears to be well formatted, yet no stories are displayed. I used an alert to copy the query string and paste it into a custom grid, which returned the expected list of stories.
Below is my code. Any assistance is appreciated.
var rallyDataSource;
var cardboard;
var ownerDropdown;
function refreshCardboard() {
var cardboardConfig = {
types: ["Defect", "HierarchicalRequirement"],
attribute: "ScheduleState",
fetch: "Name,FormattedID,Owner,ObjectID"
};
var query = rally.sdk.util.Query.and(['Iteration.Name != ""', 'Iteration.State = "Committed"']);
if (ownerDropdown) {
var ownerQuery = ownerDropdown.getValue();
if (ownerQuery != 'ALL') {
query = '(' + query + ' AND Owner.Name = "' + ownerQuery + '")';
}
}
cardboardConfig.query = query;
if (!cardboard) {
cardboard = new rally.sdk.ui.CardBoard(cardboardConfig, rallyDataSource);
cardboard.display("cardboardDiv");
} else {
cardboard.refresh(cardboardConfig);
}
}
function buildOwnerDropdown() {
var teamMembersQuery = {
key: "teamMembers",
type: "User",
fetch: "UserName,DisplayName",
query: '(TeamMemberships = /project/__PROJECT_OID__)'
};
rallyDataSource.findAll(teamMembersQuery, function (results) {
var ownerItems = [{ label: "-- ALL --", value: "ALL"}];
rally.forEach(results.teamMembers, function (teamMember) {
ownerItems.push({ label: teamMember.DisplayName, value: teamMember.UserName });
});
ownerItems.sort();
var ownerDropdownConfig = {
showLabel: true,
label: "Owner:",
items: ownerItems
};
ownerDropdown = new rally.sdk.ui.basic.Dropdown(ownerDropdownConfig);
ownerDropdown.display("ownerDropdownDiv");
});
}
function onLoad() {
rallyDataSource = new rally.sdk.data.RallyDataSource(
'__WORKSPACE_OID__',
'__PROJECT_OID__',
'__PROJECT_SCOPING_UP__',
'__PROJECT_SCOPING_DOWN__');
buildOwnerDropdown();
refreshCardboard();
}
rally.addOnLoad(onLoad);
</script>
</head>
<body>
<div id="ownerDropdownDiv"></div>
<input id="refreshButton" type="button" value="Filter" onclick="refreshCardboard()"/>
<div id="cardboardDiv"></div>
</body>

You're really close to the mark - the problem lies here:
var query = rally.sdk.util.Query.and(['Iteration.Name != ""', 'Iteration.State = "Committed"']);
if (ownerDropdown) {
var ownerQuery = ownerDropdown.getValue();
if (ownerQuery != 'ALL') {
query = '(' + query + ' AND Owner.Name = "' + ownerQuery + '")';
}
}
Rally's query syntax requires another nested set of parentheses when adding another AND condition. So when you concatenate on your third condition, you are ending up with a query clause that looks like this:
((Iteration.Name != "") AND (Iteration.State = "Committed")) AND (Owner.Name = "user#company.com")
When it needs to look like this:
(((Iteration.Name != "") AND (Iteration.State = "Committed")) AND (Owner.Name = "user#company.com"))
I slightly modified your refreshCardboard() function's query logic as follows, and your code seems to work now for me.
....
var queryArray = new Array('Iteration.Name != ""', 'Iteration.State = "Committed"');
var query;
var selectedOwner = ownerDropdown.getValue();
if (ownerDropdown) {
if (selectedOwner != 'ALL') {
var ownerClause = 'Owner.Name = "' + selectedOwner + '"';
queryArray.push(ownerClause);
}
}
query = rally.sdk.util.Query.and(queryArray);
cardboardConfig.query = query;
....

How do get param from a url

As seen below I'm trying to get #currentpage to pass client params
Can someone help out thanks.
$(document).ready(function() {
window.addEventListener("load", windowLoaded, false);
function windowLoaded() {
chrome.tabs.getSelected(null, function(tab) {
document.getElementById('currentpage').innerHTML = tab.url;
});
}
var url = $("currentpage");
// yes I relize this is the part not working.
var client = jQuery.param("currentpage");
var page = jQuery.param("currentpage");
var devurl = "http://#/?clientsNumber=" + client + "&pageName=" + page ;
});

This is a method to extract the params from a url
function getUrlParams(url) {
var paramMap = {};
var questionMark = url.indexOf('?');
if (questionMark == -1) {
return paramMap;
}
var parts = url.substring(questionMark + 1).split("&");
for (var i = 0; i < parts.length; i ++) {
var component = parts[i].split("=");
paramMap [decodeURIComponent(component[0])] = decodeURIComponent(component[1]);
}
return paramMap;
}
Here's how to use it in your code
var url = "?c=231171&p=home";
var params = getUrlParams(url);
var devurl = "http://site.com/?c=" + encodeURIComponent(params.c) + "&p=" + encodeURIComponent(params.p) + "&genphase2=true";
// devurl == "http://site.com/?c=231171&p=home&genphase2=true"
See it in action http://jsfiddle.net/mendesjuan/TCpsD/
Here's the code you posted with minimal changes to get it working, it also uses $.param as it's intended, that is to create a query string from a JS object, this works well since my suggested function returns an object from the url
$(document).ready(function() {
// This does not handle arrays because it's not part of the official specs
// PHP and some other server side languages support it but there's no official
// consensus
function getUrlParams(url) {
var paramMap = {};
var questionMark = url.indexOf('?');
if (questionMark == -1) {
return paramMap;
}
var parts = url.substring(questionMark + 1).split("&");
for (var i = 0; i < parts.length; i ++) {
var component = parts[i].split("=");
paramMap [decodeURIComponent(component[0])] = decodeURIComponent(component[1]);
}
return paramMap;
}
// no need for the extra load listener here, jquery.ready already puts
// your code in the onload
chrome.tabs.getSelected(null, function(tab) {
document.getElementById('currentpage').innerHTML = tab.url;
});
var url = $("currentpage");
var paramMap = getUrlParams(url);
// Add the genphase parameter to the param map
paramMap.genphase2 = true;
// Use jQuery.param to create the url to click on
var devurl = "http://site.com/?"+ jQuery.param(paramMap);
$('#mydev').click( function(){
window.open(devurl);
});
});
