<script async src="https://www.googletagmanager.com/gtag/js?id=Var">
I want to replace the value of the id in src of script with a variable that I get from conf file
any help?
As HTML is "read" by the web browser, you won't be able to simply add a variable to a <script> tag. You can accomplish this through pure Javascript by loading in the file dynamically as stated here: Dynamically load JS inside JS
Where id_number is the number you are attempting to add:
var url_string = 'https://www.googletagmanager.com/gtag/js?id=' + id_number
var script = document.createElement('script');
script.onload = function () {
//do stuff with the script
};
script.src = url_string;
document.head.appendChild(script);

I'm trying to append window.location.path name to source and currently it is not returning the value. Am i appending it correctly?
<script src="abc.com/gethistory?product=aj1&m=abn&lang='"+ window.location.pathname.substring(1,2)" ></script>
JavaScript isn't executed in HTML tags. You need to write a script that creates the tag with the computed URL.
var script = document.createElement("script");
script.src = "abc.com/gethistory?product=aj1&m=abn&lang="+ window.location.pathname.substring(1,2)";
document.head.appendChild(script);
Your script is not inside any other javascript code, window is a javascript object and only accessible inside a javascript script. If you want to achieve the desired outcome you can write the following script.
const script = document.createElement("script");
script.src = `abc.com/gethistory?product=aj1&m=abn&lang="${window.location.pathname.substring(1,2)}"`;
document.head.appendChild(script);
I have the following code to include in one domain (http://www.example1.com)
<script
type="text/javascript"
src="http://www.example2.com/API/incoming.php?id=560">
</script>
All this does is invoke the page incoming.php in my second domain (http://www.example2.com), and send it the value "560".
My questions are:
Is it possible to send runtime variables to the page? (Eg : I am hard coding `560`, is there any way to get it dynamically if it is part of the URL?
Would it be possible to send the page URL where this script was loaded? This is what I tried so far, but I am not able to access the variable URL.
<script type="text/javascript" src="http://www.example2.com/API/incoming.php?id=560">
var Url = "";
if (typeof this.href != "undefined") {
Url = this.href.toString().toLowerCase();
}else{
Url = document.location.toString().toLowerCase();
}
</script>
you can create the script tag dynamically and pass all the variables you like via GET.
<script>
(function() {
var id = 560;
var url = document.location.toString().toLowerCase(); // use other means if necessary
var scriptElement = document.createElement('script');
scriptElement.src = 'your.php?id=' + encodeURI(id) + '&url=' + encodeURI(url);
document.body.appendChild(scriptElement);
}());
</script>
the scriptElement will begin to load after it is inserted in the document.
this is how google analytics and others did or do it.
I have an Android application that consist in a simple WebView that load a local html file in the assets folder of the project.
The HTML has a tag that calls (AJAX) an external service and expects as a response a String that represent a .js filename (say, 'test.js').
In test.js there is a simple funcion declaration, as:
var testFunction = function(){
// some code here
}
The AJAX callback then construct via javascript a tag that points to the .js file and append it to the head of the document; then call the testFunction:
$.ajax('externalService').done(function(response){
var script = // construct the script tag;
$('head').append(script);
testFunction();
});
Important: the script tag points to an external .js file, like
<script src="http://justatest.com/test.js">
... and all works fine!
Now i try to do the same thing putting the test.js inside the assets folder of the project. Obviously i changed the src of the script created in the callback with a relative path:
<script src="test.js"></script>
but when i try to invoke the function testFunction i get an error (testFunction is not defined).
The local path is correct (i put jquery.js in the same local folder of test.js and loaded it directly in the html with a with no errors).
I put all the attributes (like type="text/javascript") in the tag as well...
so, why the webview doesn't load a local .js file in this way?
thank you :)
EDIT: I tried the solution found in this thread:
jQuery getScript not working in Android WebView when using Local Assets/HTML/Resources
and it worked!!!!
I tried the solution found in this thread:
jQuery getScript not working in Android WebView when using Local Assets/HTML/Resources
and it worked!
I report the solution:
var scriptUrl = "test.js";
var head = document.getElementsByTagName("head")[0];
script = document.createElement('script');
script.type = 'text/javascript';
script.src = scriptUrl;
script.onload = function() { alert("Success"); };
script.onerror = function(e) { alert("failed: " + JSON.stringify(e)); };
head.appendChild(script);
So if i use the jquery append() method it doesn't work, but if i use the javascript appendChild method it work...
i want to load multiple javascript file using one javascript file
i have four javascript
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
<script type="text/javascript" src="http://ec2-174-129-44-226.compute-1.amazonaws.com/apiTools/jquery.livequery.js"></script>
<script src="http://localhost/effbugs/apiTools/tools.js?apikey=fztxljpnxqtssgtiquwr&pid=1"></script>
i want to intergrate above four javascript in one javascript file that i will load one instead of four and i will work proper
please give me suggestion for that
please help me
thanks...
Well, there are a few options:
1. Combine them into one file
Here is how you can do it with cat:
cat jsfile1.js jsfile2.js jsfile3.js ... > combined.js
2. Load them via require.js
More info at requirejs.org.
3. Create an script element for each URL and append it to DOM
/**
* loader.js
*/
window.addEventListener('load', function () {
var head = document.getElementsByTagName('head')[0],
urls = ["http://code.jquery.com/jquery-1.10.1.min.js",
"http://code.jquery.com/jquery-migrate-1.2.1.min.js",
"http://ec2-174-129-44-226.compute-1.amazonaws.com/apiTools/jquery.livequery.js",
"http://localhost/effbugs/apiTools/tools.js?apikey=fztxljpnxqtssgtiquwr&pid=1"];
urls.forEach(function (url) {
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = url;
head.appendChild(script);
});
});
You can do in this way to include all js files, But while loading I guess they loads asynchronously and they might not maintain order the order.
var scriptElement = document.createElement('script');
scriptElement.src = 'http://code.jquery.com/jquery-1.10.1.min.js';
document.getElementsByTagName("head")[0].appendChild(scriptElement);
Its quite simple, you just copy the content of all 4 files and place them into 1 file in order like this.
Master.js:
// Content of jquery-1.10.1.min.js
// Content of jquery-migrate-1.2.1.min.js
// Content of jquery.livequery.js
// Content of tools.js
Or
Master.js:
var script = document.createElement('script');
script.src = 'jquery-1.10.1.min.js';
document.head.appendChild(script);
// Do this for each file
I'm using this code to include dynamically js file in run-time:
var headID = document.getElementsByTagName("head")[0];
var script = document.createElement('script');
script.type='text/javascript';
script.src="js-debug/"+record.getId()+".js";
script.onload = function() {
inizializeComponent();
}
For every node of menu, I include a different js file.
Now I need to intercept the event triggered when the page does not exist to show a messagebox!
How can I get it?
Use script.onerror = function () { ....
