I'm trying to write a value from the DOM into a Google Tag Manager Variable. I'm using the standart variable "Click Element". The Element i want to track is an HTML element with some attributes. If i let the variable be shown in the console it works like a charm. If i return the same value, google manager shows "undefined" in the debug mode.
What could be the mistake?
function() {
var e = {{Click Element}};
var namestr = e.dataset.src.split("/")[10];
console.log(namestr); //works
return namestr; //doesnt work
}
The reason was simple. I don't know why, but the "click element" variable of the Google Tag Manager is NOT filled by the element the user clicked. It uses the parent element above. So the answer is:
var namestr = e.children[0].src.split("/")[10];

In google chrome in history section, I want to delete all the histories related to a specific website for example: facebook.com, I can search facebook.com and then select all checkboxes and delete but its a time-consuming work.
Is there any easy way to clear the history of specific websites?
even by writing code or script?
open the history manager, search for facebook.com... do not click all the checkboxes individually. Click the first box, scroll to the bottom of the page and hold shift while clicking the last box, it will select all of them at once.
protip: if you want to visit a website without leaving a history entry, go into incognito mode (control-shift-p).
or, Control-A keyboard shortcut will select all of the checkboxes as well! https://techdows.com/2018/02/chrome-history-page-ctrl-a-now-selects-all-history-items.html#:~:text=Chrome%20history%20Page%3A%20Ctrl%2BA%20now%20selects%20all%20items&text=Now%20the%20addition%20of%20Ctrl,or%20unselect%20multiple%20history%20items.&text=The%20thing%20is%2C%20only%20150,page%20has%20more%20history%20items.
You can use some scripting in the console to click checkboxes for entries with hrefs containing a substring.
This answer uses this other SO answer on a querySelectorAll that works for things inside open shadow DOMs:
function $$$(selector, rootNode=document.body) {
const arr = []
const traverser = node => {
// 1. decline all nodes that are not elements
if(node.nodeType !== Node.ELEMENT_NODE) {
return
}
// 2. add the node to the array, if it matches the selector
if(node.matches(selector)) {
arr.push(node)
}
// 3. loop through the children
const children = node.children
if (children.length) {
for(const child of children) {
traverser(child)
}
}
// 4. check for shadow DOM, and loop through it's children
const shadowRoot = node.shadowRoot
if (shadowRoot) {
const shadowChildren = shadowRoot.children
for(const shadowChild of shadowChildren) {
traverser(shadowChild)
}
}
}
traverser(rootNode)
return arr
}
arr = $$$('[href*="example.com"]');
// this code will need to be updated if the source code for the chrome history browser changes.
arr.map(e => e.closest("#item-info")
.previousElementSibling
.previousElementSibling
).forEach(e=>e.click());
This will click all the matching entries on the current page, and then you can just click the button to delete the checked entries.
used jssor slider , i have some pages with same jssor slider , some pages are working fine , but some pages comes Outer container 'null' not found. bug , can any one help on this ?
I had a similar problem, so did some digging to see what the issue was.
The setup starts with the initial call, here's the snippet from the demo site
http://www.jssor.com/development/index.html
var jssor_slider1 = new $JssorSlider$("slider1_container", options);
which, among setting up all kinds of utility functions- more importantly does this
function JssorSlider(elmt, options) {
var _SelfSlider = this;
...
// bunch of other functions
...
$JssorDebug$.$Execute(function () {
var outerContainerElmt = $Jssor$.$GetElement(elmt);
if (!outerContainerElmt)
$JssorDebug$.$Fail("Outer container '" + elmt + "' not found.");
});
}
so at this point, it's trying to collect the string you passed, which is the elmt variable- which is for what? Well let's take a look at that $GetElement function in jssor.js
_This.$GetElement = function (elmt) {
if (_This.$IsString(elmt)) {
elmt = document.getElementById(elmt);
}
return elmt;
};
So, really, what it comes down to is this line for finding the element.
elmt = document.getElementById(elmt);
So the base of this error is
"We tried to use your string to find a matching ID tag on the page and it didn't give us a valid value"
This could be a typo, or another line of code modifying/removing the DOM.
Note that there are some scripts try to remove or modify element in your page.
Please right click on your page and click 'Inspect Element' menu item in the context menu.
Check if the 'outer container' is still there in the document. And check if there is another element with the same id.
Check if "Slider1_Container" is present or Used.
In my case, I didn't have it in my html, but still I had added the js.
Removing js resolved my issue.
that is we have opened many tabs.In that tabs i want to search specific tab. Please tell if any ext or option or add-on in chrome or firefox.
Firefox has this functionality built in. If you just start typing in the URL bar and the first character you type is % followed by a space, the rest of what you type will be treated as a search on the titles and urls of open tabs in all Firefox windows.
I'm not sure if this is the site to be asking for help finding extensions that do end user tasks such as this so I'll answer your question explicitly as well as explain how to do it programatically.
The short answer is, yes one extension that will allow you to do this can be found here:
Tab Title Search
The long answer is, in order to find all tabs with a certain name, you need to use the chrome tabs API
I whipped up a short piece of javascript to demonstrate how to have an extension that will create a popup with a search box that you type the desired tab title into. If the tab is found, it will be listed below the search box. If you click on the listing, you will switch to the tab.
// Function to search for tabs
function searchtabs() {
chrome.tabs.query({
title: ""
},
// Callback to process results
function(results) {
// Place holder for the tab to process
var foundTab = null;
// Text to match against
var queryText = document.getElementById("textToSearchInput").value;
// Div to place divs of matched title in
var queryAnswerDiv = document.getElementById("foundTabsDiv");
// Clear the current children
while (queryAnswerDiv.hasChildNodes()) {
queryAnswerDiv.removeChild(queryAnswerDiv.lastChild);
}
// Iterate over all the results
for (var i = 0; i < results.length; i++) {
// Keep track of the tab that is currently being processed
foundTab = results[i];
// If we have a title containing our string...
if (foundTab.title.indexOf(queryText) > -1) {
// Create a new div
var tabDiv = document.createElement("div");
// Set its content to the tabs title
tabDiv.innerHTML = foundTab.title;
// Let it know what the tabs id is
tabDiv.tabToSwitchTo = results[i].id;
// Allow for users to click on the representing div to switch to it
tabDiv.onclick = function() {
// Make the tab selected
chrome.tabs.update(this.tabToSwitchTo, {
selected: true
});
};
// Append the created div to our answer div
queryAnswerDiv.appendChild(tabDiv);
}
}
});
}
document.addEventListener('DOMContentLoaded', function() {
var inputField = document.getElementById("textToSearchInput");
inputField.focus();
inputField.onkeydown = searchtabs;
});
Also, if this is more what you are looking for rather than the extension that I linked, let me know and I can pack this extension.
Edit:
Fixed an error in using the wrong ID to get the input field as well as not getting the first letter of the title (use indexOf() > -1)
An extension that does this is Tab Hero for Chrome ($0.99 Chrome extension). It searches through all of the open tabs (across multiple windows) and offers to switch to the filtered tab. Try and see if it works for you.
Looked through the questions and there are few similar ones on the subject of "ReferenceError foo is not defined". However, I'm not able to detect the error in my code and get it working. It works fine in Chrome and Safari, but not in IE, Opera and Firefox:
The code in the HTML
<a href="javascript:foo(1)" target="_parent">
calls a javascript placed in the header as
<script type="text/javascript" src="http://www.site.com/include/script.js"></script>
which is defined as the following:
function foo(language){
url = window.parent.location.href;
parts = url.split('/');
page = parts[3];
newUrl = "";
if (language == 1){
newUrl = "http://www.site1.com/" + page;
} else if (language == 2){
newUrl = "http://www.site2.com/" + page;
} else{
newUrl = "http://www.site3.com/" + page;
}
window.parent.window.location.href = newUrl;
}
Reading the related questions I tested to change to window.foo = function(language){...}, but it didn't help.
Seems straight forward and as simple as it gets, but of some reason foo is undefined in IE and firefox.
Should be added that the javascript is in the "top.html" which is an embeded iframe for each page. Somehow chrome manages this while IE doesn't (but the script works if I browse to http://www.site1.com/top.html and click on the button calling redirect(language);)
Your problem is that the link is targeted (has a target="_parent" bit).
This means that it runs in the scope of the target window, not in the window it's in. And there is no function named foo there.
It look like your link is in a "iframe" tag, but the foo function is defined in top-level window object's scope.
There a two ways to fix this:
You should use window.partent to reference the top-level window object, try to change the link to
<a href="javascript:window.partent.foo(1)" target="_parent">
Or, move the function code to the same html file's head tag as the link.
By the way, you should use var keyword to declare variables.
I did:
function doGet() {
var app = UiApp.createApplication();
// Create a dialog box.
var dialog = app.createDialogBox();
// Add a label to the dialog and set the dimensions and position.
dialog.setPopupPosition(100, 100).setSize(500, 500).show();
// Show the dialog. Note that it does not have to be "added" to the UiInstance.
dialog.show();
return app;
}
Deployed and got:
This is obviously not what I expected.
what am I doing wrong?
Don't worry, .createDialogBox() seems to be broken. Write your entry into the issue tracker I'll star it as soon as your entry shows up there.
I use PopupPanel which works fine and gives the same functionality minus the draggability
