Get URL parameters in JS and embed into a JS function - javascript

I have a graph library that I use to plot some data.
This data comes passed as a GET paramater in the URL in the following format: plottedgraph.html?case_id=4&otherparam=blabla
Then I have my HTML page where I try to catch that GET param with the GUP function (below) and add it to my JS function as follows: "http://www.url.com/showgraph.do?case_id=" + gup('case_id') + "&status=weighted"
This is the whole HTML
<html>
<head>
<!--[if IE]>
<script type="text/javascript" src="js/excanvas.js"></script>
<![endif]-->
<script type="text/javascript" src="js/dygraph-combined.js"></script>
<script type="javascript">
function gup( name )
{
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec( window.location.href );
if( results == null )
return "";
else
return results[1];
}
</script>
</head>
<body>
<div id="graphdiv2" style="width:1800; height:900px;"></div>
<script type="text/javascript">
g2 = new Dygraph(
document.getElementById("graphdiv2"),
"http://www.url.com/showgraph.do?case_id=" + gup('case_id') + "&status=weighted", // path to CSV file
{
showRoller: true,
colors: ["rgb(255,100,100)",
"rgb(72,61,139)"]
} // options
);
</script>
</body>
</html>
Unfortunately the JS function doesn't recognize that case_id=4 in this case...
Could you please let me know what am I doing wrong?

It's a bit hard to debug you gup() function, could you try:
var params={};
document.location.search.replace(/\??(?:([^=]+)=([^&]*)&?)/g, function () {
function decode(s) {
return decodeURIComponent(s.split("+").join(" "));
}
params[decode(arguments[1])] = decode(arguments[2]);
});
You can now find your parameters in the params object, so params['case_id'] will hold the value you're looking for.

Change part of link with part of current URL

I´m new on this and I´m having a hard time tryng to do something I think must be simple.
I have a lot of pages hosted on https://www.something.com/path/NUMBER/path/path
Inside those pages I have a button that links to https://www.example.com/path/REPLACE/path
I would like to change REPLACE on my link with NUMBER on the address bar.
This is my code:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
</head>
<body>
<script>
$(document).ready(function(){
var newURL = window.location.protocol + "://" + window.location.host + "/" + window.location.pathname;
pathArray = window.location.pathname.split( '/' );
var part_2 = pathArray[2];
var mylink = "https://www.example.com/path/" + part_2 + "/path/page.html";
});
</script>
<p>BUTTON</p>
</body>
</html>
Thank you very much for your help!
try this.
Url1:- https://www.something.com/path/NUMBER/path/path;
Url2:- https://www.example.com/path/REPLACE/path;
url2 = url2.split('/').map(a => {
if(a == 'REPLACE')
return 'NUMBER';
else
return a;
}).join('/');
If you want to change using Javascript, you can do as below:
var url = "https://www.something.com/path/NUMBER/path/path";
var oldUrl = "https://www.example.com/path/REPLACE/path/path";
var regex = /https:\/\/www\.something\.com\/path\/(\w*?)\/.*/g;
var match = regex.exec(url);
oldUrl = oldUrl.replace("/REPLACE/", "/"+match[1]+"/");
console.log(oldUrl);
-- EDIT --
Another example to replace using browser URL and replace the second path without considering the remaining URL or paths .
$(document).ready(function() {
var url = window.location.href;
// As the script executed in iframe, assigning with hardcode value
url = "https://stackoverflow.com/questions/51442637/change-part-of-link-with-part-of-current-url#";
var oldUrl = "https://www.example.com/path/REPLACE/path/path";
var regex = /https:\/\/\w*?\.?\w*?\.\w*?\/\w*?\/(\w*?)\/.*/g;
var match = regex.exec(url);
oldUrl = oldUrl.replace("/REPLACE/", "/" + match[1] + "/");
document.getElementById("mylink").href = oldUrl;
});

JS automated click not working

I think i have found a solution for this one. Might be a little primitive but inserting it here until someone comes up with a better solution.
Thanks !

function makeShort()
{
var longUrl=location.href;;
var request = gapi.client.urlshortener.url.insert({

Can some one suggest why this "auto-click" function is not working in my code below?

var request = gapi.client.urlshortener.url.insert({
'resource': {
'longUrl': longUrl
}
});
request.execute(function(response) {
if (response.id != null) {
str = "<b>Long URL:</b>" + longUrl + "<br>";
str += "<b>Short URL:</b> <a href='" + response.id + "'>" + response.id + "</a><br>";
document.getElementById("output").innerHTML = str;
} else {
alert("error: creating short url n" + response.error);
}
});} window.onload = function() {
var button = document.getElementById('modal');
button.form.submit();}
function load() {
//Get your own Browser API Key from https://code.google.com/apis/console/
gapi.client.setApiKey('xxxxxxxxx');
gapi.client.load('urlshortener', 'v1', function() {
document.getElementById("output").innerHTML = "";
});} window.onload = load;
<html>
<input type="button" id="modal" value="Create Short" onclick="makeShort();" /> <br/> <br/>
<div id="output">Wait. Loading....</div>

My basic aim is to insert a "share via email" button on the page which would shorten the url on the address bar and open user's email client/whatsapp app to share that url..
Obviously I could not find a way to combine these two functions in to one since I am not a very experienced js person. The primitive solution I found is to auto-click the first function, get the short url, and then find a different code to insert this in to the body of the "mailto" link, which will be my 2nd challenge.
To programmatically click a button on page load
If you are using jQuery:
$(function() {
$('#modal').click();
});
Plain javascript:
window.onload = function(){
var event = document.createEvent('Event');
event.initEvent('input', true, true);
document.getElementById("modal").dispatchEvent(event);
};

Writing a string to text file with Javascript

We are attempting to save a URL stored in a string to a text file, but we can't seem to get it to work. It will not save into the file, although our testing shows that the function is actually running when it should be.
The code for this is here:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<button onclick="instagramclick()">Login to instagram</button>
<button onclick="myFunction()">Test Button</button>
<script>
function myFunction() {
alert("Hello World");
}
function instagramclick(){
alert("button clicked");
window.location.href = "https://instagram.com/oauth/authorize/?client_id=8a612cd650344523808233c0468c80ed&redirect_uri=http://u-ahmed.github.io/HookedUp/instagram.html&response_type=token";
}
function WriteDemo(link)
{
var fso, f, r;
var ForReading = 1, ForWriting = 2;
fso = new ActiveXObject("Scripting.FileSystemObject");
f = fso.OpenTextFile("database.txt", ForWriting, true);
f.Write(link);
f.Close();
r = f.ReadLine();
return(r);
}
window.onload = function writedamnyou(){
var token = window.location.href.substring(62);
if (token != ""){
// document.write(token);
var link = "https://api.instagram.com/v1/users/self/feed?access_token=" + token;
// w = window.open('database.txt')
WriteDemo(link);
// document.write(stuff);
}
};

How to reflect JStree changes to the original XML?

I'm using JStree to display an XML file, and after displaying it the user can create, rename, or delete some nodes, and sor sure these changes appear only on the displayed xml and not reflected on the original file, I want to know how to reflect this changes to the original XML fie back after clicking like a submit button, or at least how to get the data changed.

<body>
<div id="dummy"></div>
<div id="mylist">
<li id='root'><a href='#'>Root node</a><ul><li><a href='#'>Child node</a></li></ul></li>
</div>
<div id="submit" class="submit_btn">Submit</div>
</body>
<script type="text/javascript" class="source below">
var _url = "cafe.xml";
var _uimTree = null;
$(function () {

And the UIMtreeprocessor Library code
function UIMTreeProcessor(data, treeEl) {
this.data = data;
this.treeEl = treeEl;
}

var _a_feed = new Array();
this.vsTraverse($(_root), _a_feed);
var _treedata = [{"data":_root[0].nodeName,"children":_a_feed, "state":"open"}];
this.initTree(_treedata);

UIMTreeProcessor.prototype.vsTraverse = function(node, arr){
var _ch = $(node).children();
for(var i=0; i<_ch.length; i++){
var _vsArr = new Array();
this.vsTraverse(_ch[i], _vsArr);
var _a_att = this.vsTraverseAtt(_ch[i]);
if(null!=_a_att){
_vsArr.push([{"data":"Attributes "+"["+_ch[i].nodeName+"]","children":_a_att, attr : { "class" : "uim_attr"}}]);

if(null!=_ch[i].firstChild && 3==_ch[i].firstChild.nodeType){

}else{
arr.push([{"data":_ch[i].nodeName,"children":_vsArr, "state":"open"}]);
}
}
}
UIMTreeProcessor.prototype.vsTraverseAtt = function(node){
var _a_atts = null;
if(null!=node.attributes && node.attributes.length > 0){
_a_atts = new Array();
for(var i=0; i<node.attributes.length; i++){
_a_atts.push(node.attributes[i].nodeName + ":" + node.attributes[i].nodeValue);
}
}
return _a_atts;
}
Edit: I was really wrong in my original answer.
There is a get_xml method in the xml_data plugin, which is supposed to do what you describe. I have not tested it myself, but if it's anything like json_data.getJSON, the output will contain all kinds of JStree metadata which you will not want to put back into your XML.

How to convert a document back to string?

I need a java script function that converts the document object of the current loaded page back to it's source text. In firefox it's smth like that:
var doc = document;
var str = (new XMLSerializer()).serializeToString(doc);
alert(str);
But i need a cross browser solution. How would this be done?
For example:
<html>
<body>
<script>
alert( asText(document) );
</script>
</body>
</html>
would pop up:
<html>
<body>
<script>
alert( asText(document) );
</script>
</html>
how would you implement the 'asText' function?
Why do not you use document.documentElement.innerHTML?
example
function sourceText(){
try{
var O= new XMLHttpRequest();
O.open('GET', location.pathname, false);
O.send(null);
return O.responseText;
}
catch(er){
return '';
}
}
