email is not displaying inside image - javascript

Hi I have a page where after confirmation email is displaying. I want to display that email inside image link.
For this I have used this code, but I get email variable null here.
<HTML>
<head>
<script type="text/javascript">
var formData = function() { var query_string = (location.search) ? ((location.search.indexOf('#') != -1) ? location.search.substring(1, location.search.indexOf('#')) : location.search.substring(1)) : '';
var elements = [];
if(query_string) {
var pairs = query_string.split("&");
for(i in pairs) {
if (typeof pairs[i] == 'string') {
var tmp = pairs[i].split("=");
var queryKey = unescape(tmp[0]);
queryKey = (queryKey.charAt(0) == 'c') ? queryKey.replace(/\s/g, "_") : queryKey;
elements[queryKey] = unescape(tmp[1]);
}
}
}
return {
display: function(key) {
if(elements[key]) {
document.write(elements[key]);
}
else {
document.write("<!--If desired, replace everything between these quotes with a default in case there is no data in the query string.-->");
}
}
}
}
(); </script>
</head>
<body>

<script type="text/javascript">formData.display("email")</script>
<img src="http://mountainfallsmedia.go2cloud.org/SL22?adv_sub="email" width="1" height="1" />
<!-- // End Offer Conversion -->
</body></HTML>
If you look at the last lines of code you can see formData.display("email"), it uses to display email, it is working fine, but its not working in case of
<img src="http://mountainfallsmedia.go2cloud.org/SL22?adv_sub="email" width="1" height="1" />
I have tried by passing formData.display("email") instead of email, but it still returns blank.

I'm not sure what exactly what your question is, or exactly what you're trying to do, but you may want replace
src="http://mountainfallsmedia.go2cloud.org/SL22?adv_sub="email"
with
src='http://mountainfallsmedia.go2cloud.org/SL22?adv_sub="email"'
(Note the single quotes encapsulating your url.)

define a herf link based on if/else scenario in JS file

So basically I'm a beginner in JavaScript and HTML and trying to play with functions call on JS that will edit my HTML file.
Now, I'm trying to redirect users to different pages based on their type.
I want to use "onload" function in order to determine the user type and edit the link according to the result.
HTML:
<body onload="what_user()">
<div id="result">zone</div>
</body>
JS file:
function what_user() {
var d = document.getElementById("result");
var user = ""; // get the user type
if (user == "") d.outerHTML = "" + "";
else d.outerHTML = "" + "";
}
I have some problems understanding how to call a function from HTML and use it on JS as well as return values.
Thanks in advance!!!
Don't play with elements as string. Create an element and put it where you want.
function what_user() {
var d = document.getElementById("result");
let a = document.createElement('a')
a.text = 'zone'
var user = ""; // get the user type
if (user == "") a.href = 'admin_index.html'
else {
a.href = 'admin_user.html'
}
d.parentNode.removeChild(d);
document.body.appendChild(a)
}
<body onload="what_user()">
<div id="result">zone</div>
</body>

How do I launch a site on Chrome/Firefox by pressing a key or preferably 2 keys

I have this keyboard site launcher script, which I copied from some place years ago and it works fine as is. I want to enhance it by adding a cascading keypress launch for some of the keys. Here is my code:
<html><head>
<script language="JavaScript">
<!-- Begin
var key = new Array();
key['a'] = "https://www.arstechnica.com";
key['g'] = "https://www.google.com";
key['s'] = "https://slashdot.org";
key['y'] = "http://www.yahoo.com";
function getKey(keyStroke) {
isNetscape=(document.layers);
eventChooser = (isNetscape) ? keyStroke.which : event.keyCode;
which = String.fromCharCode(eventChooser).toLowerCase();
// alert('['+which+'] key \n has been stroke');
runUrl(which);
}
function runUrl(which) {
for (var i in key)
if (which == i) {window.location = key[i];}
}
document.onkeypress = getKey;
// End -->
</script></head>
<body>
Make a selection<br>
<br>
key['a'] = "https://www.arstechnica.com";
key['g'] = "https://www.google.com";
key['s'] = "https://slashdot.org";
key['y'] = "http://www.yahoo.com";
<br>
<br>
<!-- I solemnly swear this page is coded with vi or notepad.exe depending on the OS being used -->
</body>
</html>
Now, I want to modify the action for pressing the letter "s" to launch a submenu of sorts and ask me to select if I want to go to "Slashdot" or Spotify" for instance. like if I press an "s" second time, it goes to slashdot and if I press "f" for instance, it goes to spotify.
My problem is, I have never programmed in Javascript other than copying and pasting code and changing string values in the code, like here, changing the pressed keys and site URLs.
Any pointers, regarding how to start modifying this code, are greatly appreciated.
to be honest, the code provided is a bit outdated but I keep it so you can see the necessary changes that I made for the menu to be added and to implement the feature it's just a sketch but I will do the job I think from here you can expand, hope this puts you in the right direction
let isopenMenu = true;
const menu = document.getElementById("menu");
function toggleMenu() {
isopenMenu = !isopenMenu;
menu.style.display = isopenMenu ? "block" : "none";
}
var key = new Array();
key["a"] = "https://www.arstechnica.com";
key["g"] = "https://www.google.com";
key["s"] = "https://slashdot.org";
key["y"] = "http://www.yahoo.com";
key["b"] = "http://www.stackoverflow.com";
key["c"] = "http://www.test.com";
const menuSite = ["b", "c", "s"];
function getKey(keyStroke) {
isNetscape = document.layers;
eventChooser = isNetscape ? keyStroke.which : event.keyCode;
which = String.fromCharCode(eventChooser).toLowerCase();
runUrl(which);
}
function runUrl(which) {
for (var i in key)
if (which == i) {
if (which === "s") {
return toggleMenu();
}
if (!isopenMenu && menuSite.includes(which)) {
return;
}
window.location = key[i];
}
}
document.onkeypress = getKey;
window.addEventListener("load", toggleMenu);

Indeed the code you've provided seems a bit dusted. There's some stuff that isn't done in that way nowadays. Notepad is an editor I still occassionally use though.
Since you've mentioned that you never really used JavaScript it's a bit hard to give you advice. You can do things way more elegant and even improve the look - but I'd say this would just confuse you even more. So let's work on something based on your code.
At the moment the keys and the corresponding targets are stored in an object (yeah, it's an object not an array). We can use a second object - let' say subKey - to store the additional targets upon pressing s.
var key = {};
key.a = "https://www.arstechnica.com";
key.g = "https://www.google.com";
key.s = "subMenu";
key.y = "http://www.yahoo.com";
var subKey = {};
subKey.a = "https://www.stackoverflow.com";
subKey.g = "https://www.startpage.com";
subKey.s = "goBack";
As you can see I've reserved the key s to go to the sub menu and inside the sub menu this button is used to go back to the main menu.
Now instead of hardcoding what the user gets to see on screen, we can iterate over those objects and use the information from there. To do this we need to reserve a html element - I've chosen an empty <div> which acts as some sort of container. As we iterate over the object we construct a string with the keys and it's associated targets and ultimately assign this this to the div's .innerHTML property.
let container = document.getElementById("container");
container.innerHTML = "Make a selection<br><br>";
for (var i in obj) {
container.innerHTML += "key['" + i + "'] = " + obj[i] + "<br>";
}
As the procedure is the same for both objects we just need to wrap it inside a function and pass it a reference to the desired object.
Your runUrl function needs to be modified a bit to take care of the additional options. This is best done with a simple if-else construct. So in pseudo-code:
if choice is subMenu open sub menu
if choice is goBack open main menu
if it's none of the above open a link
If we put everything together, your example looks a little bit like this:
(Just click on 'Run code snippet' and make sure to click somewhere inside the window so it'll have key focus)
<html>
<head>
</head>
<body>
<div id="container">
</div>
</body>
<script type="text/javascript">
var key = {};
key.a = "https://www.arstechnica.com";
key.g = "https://www.google.com";
key.s = "subMenu";
key.y = "http://www.yahoo.com";
var subKey = {};
subKey.a = "https://www.stackoverflow.com";
subKey.g = "https://www.startpage.com";
subKey.s = "goBack";
var currentObj = key;
function getKey(event) {
let which = String.fromCharCode(event.keyCode).toLowerCase();
runUrl(which)
}
function runUrl(which) {
for (var i in currentObj) {
if (which == i) {
if (currentObj[i] != "subMenu") {
if (currentObj[i] != "goBack") {
window.location = currentObj[i];
} else {
populateMenu(key);
}
} else {
populateMenu(subKey);
}
}
}
}
function populateMenu(obj) {
currentObj = obj;
let container = document.getElementById("container");
container.innerHTML = "Make a selection<br><br>";
for (var i in obj) {
container.innerHTML += "key['" + i + "'] = " + obj[i] + "<br>";
}
}
populateMenu(key);
document.onkeypress = getKey;
</script>
</html>
It looks like could achieve this with arbitrary list of sites. If so, you could handle this a little more generically by providing a list of sites and filtering the sites based on keystrokes.
If so, you can achieve it with the following:
const sites = [
'https://www.arstechnica.com',
'https://www.google.com',
'https://mail.google.com',
'https://slashdot.org',
'https://spotify.com',
'http://www.yahoo.com',
];
let matches = sites;
document.getElementById('keys').addEventListener('keyup', event => {
const keys = event.target.value.toLowerCase().split('');
matches = sites
.map(site => ({ site, stripped: site.replace(/^https?:\/\/(www\.)?/i, '')})) // strip out https://wwww. prefix
.filter(site => isMatch(site.stripped, keys))
.map(site => site.site);
if (event.keyCode === 13) {
if (matches.length === 0) {
alert('No matches');
} else if (matches.length === 1) {
alert(`launching ${matches[0]}`);
} else {
alert('More than one match found');
}
matches = sites;
}
document.getElementById('matches').textContent = matches.join(', ');
});
// find sites matching keys
function isMatch(site, keys) {
if (keys.length === 0) return true;
if (site.indexOf(keys[0]) !== 0) return false;
let startIndex = 1;
for (let i = 1; i < keys.length; i++) {
let index = site.indexOf(keys[i], startIndex);
if (index === -1) return false;
startIndex = index + 1;
}
return true;
}
document.getElementById('matches').textContent = matches.join(', ');
<div>Keys: <input type="text" id="keys" autocomplete="off" /> press Enter to launch.</div>
<p>Matches: <span id="matches" /></p>
The key parts to this are:
Define a list of sites you want to handle
Ignore the the https://wwww prefixes which is achieved with site.replace(/^https?:\/\/(www\.)?/i, '')
Implement filter logic (in this case it is the isMatch method) which tries to match multiple keystrokes
For demonstration purposes, I've wired keyup to an input field instead of document so that you can see it in action, and the action is triggered with the enter/return key.

Verify specific input value

First off, thanks for anyone's help on this. I have an input id #Mailer_Code. I want to submit a specific value based on whether this mailer code value matches the user's value or not, and create 2 different IDs based on whether this value is valid or not.
In general terms:
ID is 1234;
if Mailer_Code is yourock, then ContactID is DWID
if Mailer_Code is not yourock, then ContactID is WWID
I would really appreciate if "yourock" was some sort of comma separated list so the Mailer_Code could be any of the specified values. ie. #Mailer_Code = "yourock, or yourawesome, or supercool, etc." (not case sensitive)
Also, if the #Mailer_Code is anything other than the list of allowed values, it simply returns a #Mailer_Code of "none" and WW1234.
So far I'm here:
if ( $('#Mailer_Code').val = "yourock" ) {
contactSource = "DW";
mailer_true_false = "true";
}
else {
contactSource = "WW";
mailer_true_false = "false";
$("#Mailer_Code").val('0');
}
Any help is much appreciated. Thanks for reading.
The following should get you started.
Note that instead of a comma separated list of valid values I added them to an array. jQuery has a very useful array function inArray that makes checking the values a simple matter.
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
</head>
<body>
<div>
<span id="Mailer_Code">yourock</span>
<span id="Id">1234</span>
</div>
<span id="ContactId"></span>
<script type="text/javascript">
var arr = [ "yourock", "youareawesome", "youarethebest" ];
var inListPrefix = "DW";
var outListPrefix = "WW";
var mailerCode = $("#Mailer_Code").text();
var pre = "";
if (jQuery.inArray(mailerCode, arr) >= 0)
{
pre = inListPrefix;
}
else
{
pre = outListPrefix;
$("#Mailer_Code").text("none");
}
$("#ContactId").text(pre + $("#Id").text());
</script>
</body>

change the value of parameter in URL

I'm trying to make a javascript function to change the value of a parameter in the URL with the value inputed in a text box, with no luck. That's because I'm note a code designer but a graph one.
this is the URL where I need to change the "City" parameter:
http://server/ad_new_customer.php?&city=&uri=http://server/adauga_exp.php
I am generating data in the input text box through a MySQL query with jQuery like this:
<input type='text' id='city' name='city' style="width:190px; align:left;" value="<?php echo $city; ?>" /> </td>
<script type="text/javascript">
//change the value of parameter in the URL function
function changeURI(key, value) {
var query = document.location.search.substring(1);
var query_q = query.split("?");
var vars = query_q[1].split("&");
for (var i = 0; i < vars.length; i++) {
var pair = vars[i].split("=");
if (pair[0] == key) {
vars[i] = pair[0] + "=" + value;
}
}
return vars.join("&");
}
//jQuery making the auto-suggestion query for the input ID
$().ready(function() {
$("#city").autocomplete("core/exp_city.php", {
width: 340,
matchContains: true,
selectFirst: false
}).return(changeURI("city", this.value}));
});
</script>
How can I make it change the value the parameter on selected value?
Please advise, again, a humble designer.
Thank you!
L.E.
I have made an workaround, changed the changeURI() function with this one:
function changeURI(key, value)
{
key = escape(key); value = escape(value);
var kvp = document.location.search.substr(1).split('&');
var i=kvp.length; var x; while(i--)
{
x = kvp[i].split('=');
if (x[0]==key)
{
x[1] = value;
kvp[i] = x.join('=');
break;
}
}
if(i<0) {
kvp[kvp.length] = [key,value].join('=');
}else{
//this will reload the page, it's likely better to store this until finished
document.location.search = kvp.join('&');
}
}
Found on StackOverflow and call it from the jQuery query with the $.result() function:
<script type="text/javascript">
$().ready(function() {
$("#city").autocomplete("core/exp_city.php", {
width: 340,
matchContains: true,
selectFirst: false
}).result(function() {changeURI("city",this.value)});
});
</script>
What error are you getting? are you getting any javascript error? Also, try changing your code to some thing like
url = url.replace(new RegExp("city=", 'g'), "city="+value).
Also, The URL written in the question should not have & before city parameter as the first parameter starts with a ?, so the URL should be :
http://server/ad_new_customer.php?city=&uri=http://server/adauga_exp.php
Check if that was the issue.
In your example, document.location.search.substring(1) is already getting rid of the question mark: it should return &city=&uri=http://server/adauga_exp.php. Then doing a split on "?" and trying to take the second array element should return undefined, because there are no longer any "?" characters. Skip straight to var vars = query.split("&") at that point, and the rest looks okay to me.

Get source of image

I have a next string like:
<img src="../uplolad/commission/ranks/avatar.jpg' . $row[$c_name] .'" width="50" height="50"/>
How can i get a image file name in javascript? I know only PHP regexes. Extention of a file can be different.
The result must be: avatar.jpg
Regex is not ideal for this. JavaScript can traverse the HTML as distinct objects more readily than as a long string. If you can identify the picture by anything, say by adding an ID to it, or an ID to a parent with that as the only image, you'll be able to access the image from script:
var myImage = document.getElementById('imgAvatar'); // or whatever means of access
var src = myImage.src; // will contain the full path
if(src.indexOf('/') >= 0) {
src = src.substring(src.lastIndexOf('/')+1);
}
alert(src);
And if you want to edit, you can do that just as well
myImage.src = src.replace('.jpg', '.gif');
Fetch it following coding which can help what you want to get.
<script type="text/javascript">
function getImageName(imagePath) {
var objImage = new RegExp(/([^\/\\]+)$/);
var getImgName = objImage.exec(imagePath);
if (getImgName == null) {
return null;
}
else {
return getImgName[0];
}
}
</script>
<script>
var mystring = getImageName("http://www.mypapge.mm/myimage.png")
alert(mystring)
</script>
Here's a shorter variation of David Hedlund's answer that does use regex:
var myImage = document.getElementById('imgAvatar'); // or whatever means of access
alert(myImage.src.replace( /^.+\// , '' ));
