I am using Internet Explorer.
I added a context menu item (through the registry) such that when right clicking on a link in a webpage a custom menu item pops up. Upon selection, this menu item runs some javascript code.
I want to use the url of the link (on which I right click) in the javascript code - how do I access that url?
*Note that this should work for any webpage, not only ones which I have control over.
Thanks in advance!
<script language="JavaScript">
var parentwin = external.menuArguments;
var doc = parentwin.document;
var url = doc.URL;
// ... the rest of your code here ...
See also.
To get the source object, try:
<script language="JavaScript">
var parentwin = external.menuArguments;
var srcElement = parentwin.event.srcElement;
if (srcElement.tagName == "A") {
var url = srcElement.href;
// ... the rest of your code here ...
}

Essentially, I would like to querySelect a specific text node on the page and replace that node's textContent/data. I have successfully done this via Chrome Console, but when I try to replicate the steps in Tag Manager, I'm seeing nothing happen.
Here is the structure of the relevant portion:
The phone number I need to replace is blacked out. As you can see, I can querySelect this by targeting span.telephone b and then the second childNode.
Here is the node tree for the b element:
The steps I went through in the Console were...
var ogtel = document.body.querySelector("span.telephone b");
var split = ogtel.childNodes[1];
split.textContent;
" (555) 555-5555"
split.replaceData(0,15," new telly baby");
But when I fire a Custom HTML tag in GTM that does the same thing, it shows the tag successfully firing, but that number on the page isn't replace in preview mode.
Here's that Custom HTML tag script. I tried replaceData() and deleteData()...
<script> ( function () {
var ogtel = document.body.querySelector("span.telephone b");
var tel = ogtel.childNodes[1];
var tel2 = tel.deleteData(0,15);
} ) </script>
Any idea what I'm doing wrong? Can GTM even select/edit/delete text data within nodes like this?
ANSWERED!
I wasn't activating the function (like an idiot...)
New GTM code that works..
<script> function changeTel() {
var ogtel = document.body.querySelector("span.telephone b");
var tel = ogtel.childNodes[1];
var tel2 = tel.deleteData(0,15);
}
change = changeTel();
</script>
So this has been asked a number of times on here, and while I've read all of the threads I can find, this still isn't working for me.
A little background: I'm working on a Wordpress site with a grid plugin, and I'm trying to trigger a filter when the page loads, depending on a url parameter. For the purpose of this thread I've just hardcoded a url parameter (the category variable) as an example because that functionality is working fine.
The anchor tag I'm trying to trigger:
Tarps and Covers
The broken code I'm trying to use to trigger the click event:
<script type="text/javascript">
$(document).ready(function() {
var hash = window.location.hash;
var category = '55';
var anchor = $("[data-category=" + category + "]");
anchor.click();
});
</script>
A console log returning the anchor variable confirms that I'm selecting the correct jQuery object, and I've also tried anchor[0].click() to trigger it with no success. Does anyone see any problems that I'm overlooking?
I tried it :
$(document).ready(function() {
var hash = window.location.hash;
var category = '55';
var anchor = $("[data-category=" + category + "]");
anchor.click();
anchor.on('click',()=>{
alert();
})
});
Everything is working
I have Javascript code that opens ISBNs of books on Amazon using hyperlinks (feel free to try, for example: 0133098648). I would like the URL to open up on a new window with all links clicked in a new tab on that same window. It appears one can only open in a new tab of the current window, or a new window every time.
Is what I am looking to do even possible? I've been reading that something like this is restricted by browsers for security reasons; Maybe there's a work around? I've been pulling my hair out trying to find a solution for this, if I could it would make my life much more easier.
A picture to describe my question: http://imgur.com/a/5lUP4
Please use JSfiddle example: http://jsfiddle.net/mq1efed2 ( Code does not work on Stackoveflow)
<html>
<div><b>ISBN Hyperlinker</b></div>
<textarea id=numbers placeholder="paste isbn numbers as csv here" style="width:100%" rows="8" >
</textarea>
<div><b>Hyperlinked text:</b></div>
<div id="output" style="white-space: pre"></div>
<script>
//the input box.
var input = document.getElementById('numbers');
var output = document.getElementById('output')
var base =
'https://www.amazon.ca/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords='
//adding an event listener for change on the input box
input.addEventListener('input', handler, false);
//function that runs when the change event is emitted
function handler () {
var items = input.value.split(/\b((?:\d\s*?){10,13})\b/gm);
// Build DOM for output
var container = document.createElement('span');
items.map(function (item, index) {
if (index % 2) { // it is the part that matches the split regex:
var link = document.createElement('a');
link.textContent = item.trim();
link.setAttribute('target', '_blank');
link.setAttribute('href', base + item.replace(/\D+/g, ''));
container.appendChild(link);
} else { // it is the text next to the matches
container.appendChild(document.createTextNode(item))
}
});
// Replace output
output.innerHTML = '';
output.appendChild(container);
}
handler(); // run on load
</script>

No, this isn't possible. Web pages cannot dictate whether or not content opens up in tabs or new windows. It's up to the user/browser to decide.
At best, you can open a new window with window.open(), but that doesn't give you control over tabs in a specific window later.
i want to open on every new site load another random tab with content.
i think i have to do it with some java script but it don´t work.
You can look at the page here: LINK
Thanks for helping.
use this code :
var items = $('[data-toggle=pill]');
var i = parseInt(Math.floor(Math.random()*items.length));
$('#tabs a:eq(' + i + ') ').tab('show');
Select all available tabs (the code below uses jQuery which is available on your page)
Draw a random item
"Simulate" a click event
You can do it like this:
$(function () {
var items = $('[data-toggle=pill]');
var randomItem = items[Math.floor(Math.random()*items.length)];
randomItem.trigger('click');
});
I have 2 windows home.html and result.html.
In home.html I have a <textarea> #txtinput and a <button> #btn.
In result.html I have another <textarea> #txtresult.
On home.html, if I enter a value into #txtinput and click #btn, I want to open result.html and pass the value of #txtinput into #txtresult.
I've tried the below code from another post, which displays the value in the new window's body but won't display it in my element
var myWindow = window.open();
myWindow.document.body.innerHTML = document.getElementById("txtinput").value;
Is it somehow possible in a simple way? I am relatively new to JavaScript, my courses are ongoing now and I am just curious to know the ways to do it. Any detailed help will be very much appreciated!
I hope i need to elaborate the below code
Button on click function in the home page:
function sample(){
//this will set the text box id to var id;
var id = document.getElementById("text_box_id").id;
//the sessionStorage.setItem(); is the predefined function in javascript
//which will support for every browser that will store the sessions.
sessionStorage.setItem("sent", id);
//this is to open a window in new tab
window.open("result.html","_blank");
}
Retrieve the value in result page:
$(document).ready(function(){
//This sessionStorage.getItem(); is also a predefined function in javascript
//will retrieve session and get the value;
var a = sessionStorage.getItem("sent");
alert(a);
});
For more information about sessionStorage

I have done same thing as above, am getting values in new window that's great, but that values I am getting only in documet.ready() function. So I am not able to use these values in my JSP. once I got values I need to display them in JSP.
I hope this code help you
This should be in home page:
function sample(id) {
sessionStorage.setItem("sent", id);
window.open("result.html","_blank");
}
This is another way in the same home page function:
function sample() {
var id=document.getElementById("your_required_id").id;
sessionStorage.setItem("sent", id);
window.open("result.html","_blank");
}
This should be in result page:
function sample1() {
var a=sessionStorage.getItem("sent");
alert(a);
}
The id may be your text box id
In result.html, find the Window which opened it, using window.opener and then take your data of interest from that Window.
window.addEventListener('load', function () { // wait for ready
var home = window.opener, txtinput, txtresult;
if (home) {
txtinput = home.document.getElementById("txtinput");
txtresult = document.getElementById('txtresult');
txtresult.value = txtinput.value;
}
}, false);
In home.html, listen for a click on #btn and open result.html
// assuming button exists at invocation time
var btn = document.getElementById('btn');
btn.addEventListener('click', function () {
window.open('result.html');
}, false);
i think that a simple assignment, using the window.opener handle from within the child window, is what you need:
if (window.opener) document.getElementById("#txtresult").value = window.opener.document.getElementById("#txtinput").value;
