I'm placing an Amazon banner inside an angular material 2 card.But the problem is that it is not rendering.It shows empty div.What could be the reason.Below is the code showing how I did it.
<md-card class="full-width full-height border-box ">
<div class="adv">
<script type="text/javascript" language="javascript">
var aax_size = '728x90';
var aax_pubname = 'XXXXXXXXXXX';
var aax_src = '302';
</script>
<script type="text/javascript" language="javascript" src="http://c.amazon-adsystem.com/aax2/assoc.js"></script>
</div>
</md-card>
I also tried to to bind it using property binding
<span [innerHTML]="advertisement()"></span>
advertisement(){
return `<div class="adv">
<script type="text/javascript" language="javascript">
var aax_size = '728x90';
var aax_pubname = 'XXXXXXXXXXX';
var aax_src = '302';
</script>
<script type="text/javascript" language="javascript" src="http://c.amazon-adsystem.com/aax2/assoc.js"></script>
</div>`;
}
I also tried to dynamically add the div inside my card,it shows inside the div but the banner doesn't appear.Below is the code showing how I did that.
ngAfterViewInit() {
let x: HTMLElement = document.getElementById('adv');
let s: HTMLScriptElement = document.createElement('script');
s.type = 'text/javascript';
// s.language = 'javascript';
let code = `var aax_size = '728x90';
var aax_pubname = 'XXXXXXX';
var aax_src = '302';`;
let src = document.createElement('script');
src.type = 'text/javascript';
// src.language = 'javascript';
src.src = 'http://c.amazon-adsystem.com/aax2/assoc.js';
try {
s.appendChild(document.createTextNode(code));
x.appendChild(s);
x.appendChild(src);
} catch (e) {
s.text = code;
document.body.appendChild(s);
}
console.log(x);
}
After scrapping every post in SO regarding or similar to this question I did not find any solution to this.I followed almost everything in those posts but nothing was working for me.After that I came across postscribe library which does the externally loading of any third party script.
First I installed the library and imported it in my component
import * as postscribe from 'postscribe';
After that all I did was calling a function inside my ngAfterViewInit function, by targetting the div with its id which in my case was adv and passed the script as a second parameter to this function.
ngAfterViewInit() {
postscribe('#adv', `<script type="text/javascript" language="javascript">
var aax_size='728x90';
var aax_pubname = 'XXXXXXXX';
var aax_src='302';
</script>
<script type="text/javascript" language="javascript" src="http://c.amazon-adsystem.com/aax2/assoc.js"></script>`);}
By doing this my banner was loaded.

Inside my JS function I need to add this:
< script src=https://xxxx.com/c3.js type="text/javascript" async defer>< /script>
How to edit the code the right way?
<script>
function affilate() {
var ab_instance = "xxx.com";
var ab_kampan = 3;
var ab_cena = 1;
var ab_id_transakce = document.getElementById("email").value;
<script src=https://xxxx.com/c3.js type="text/javascript" async defer></script>
console.log(ab_id_transakce);
}
</script>
If I understand your question correctly, you are trying to add a script tag to the DOM. It seems that you are trying to add the HTML script tag in the Javascript function, which will not work. What you can try is:
Add the script tag directly in the HTML like this:
<script src=https://xxxx.com/c3.js type="text/javascript" async defer></script>
<script>
function affilate() {
var ab_instance = "xxx.com";
var ab_kampan = 3;
var ab_cena = 1;
var ab_id_transakce = document.getElementById("email").value;
console.log(ab_id_transakce);
}
</script>
Add the script tag dynamically
<script>
function affilate() {
var ab_instance = "xxx.com";
var ab_kampan = 3;
var ab_cena = 1;
var ab_id_transakce = document.getElementById("email").value;
console.log(ab_id_transakce);
var script_tag = document.createElement("script");
script_tag.src = "https://xxxx.com/c3.js";
script_tag.type = "text/javascript";
script_tag.async = true;
script_tag.defer = true;
// in case you want to add the script tag to the <head>
document.head.appendChild(script_tag);
// in case you want to add the script tag to the <body>
document.body.appendChild(script_tag);
}
</script>
I'm trying to make a javascript function to call another .js file like this:
scriptCaller.js
function callScript(file){
var script = document.createElement('script');
script.id = file;
script.type = 'text/javascript';
script.async = true;
script.src = "script/"+file+".js";
document.getElementById('scriptSection').appendChild(script);
}
Then I create some class to be called by that script in other file:
divGenerator.js
function divGenerator(){
var self = this;
var div = document.createElement('div');
this.tag = function(){
return div;
}
/*and some other function to style the div*/
}
Then i make the main file to be executed:
main.js
function build(){
callScript('divGenerator');
}
function main(){
var test = new divGenerator();
/*execute some function to style the div*/
document.getElementById('htmlSection').appendChild(script);
}
All the three file will be called in a HTML files that will execute the main function:
myPage.html
<html>
<head>
<title>myPage</title>
</head>
<script src="scriptCaller.js"></script>
<script src="main.js"></script>
<body>
<div id="htmlSection"></div>
<div id="scriptSection"></div>
</body>
</html>
<script>build();</script>
<script>main();</script>
If I correct it should display the styled div, but what I got is an error that said:
TypeError: divGenerator is not a constructor[Learn More]
But, when I move the divGenerator() class to myPage.html it works fine. Any idea to solve this problem?
You need to add scriptCaller.js and divGenerator.js to your html script element.
<html>
<head>
<title>myPage</title>
</head>
<script src="scriptCaller.js"></script>
<script src="main.js"></script>
<script src="scriptCaller.js"></script>
<script src="divGenerator.js"></script>
<body>
<div id="htmlSection"></div>
<div id="scriptSection"></div>
</body>
</html>
<script>build();</script>
<script>main();</script>
You have couple of problems in your code. First of all, do not assign id to script element same as the "exported" global constructor name. You need to remember that anything with id attribute (and name) automatically gets exposed as global variable on window object. It means that divGenerator in your case is going to be reference to HTMLScriptElement, not a constructor function.
Second problem is related to timing, since you are loading script with async attribute. This is good, but you need to realise that in this case you can't expect that script will be loaded when you call main after build(). I would suggest to wrap script creation into promise:
function callScript(file){
return new Promise(function(resolve) {
var script = document.createElement('script');
script.id = 'script-' + file; // Note different id
script.async = true;
script.src = "script/" + file + ".js";
script.onload = resolve
document.getElementById('scriptSection').appendChild(script);
})
}
and use it like this:
<script>
build().then(function() {
main();
})
</script>
Currently I am using three external JS file.
<script src="https://code.jquery.com/jquery-2.0.0.min.js" type="text/javascript"></script>
<script src="http://example.com/jquery.cookie.js" type="text/javascript"></script>
<script src="http://example.com/js.cookie.js" type="text/javascript"></script>
I like to make all three JS file in one.
Do it possible. i create aio.js and inside aio.js
src="https://code.jquery.com/jquery-2.0.0.min.js";
src="http://example.com/jquery.cookie.js";
src="http://example.com/js.cookie.js";
And then i will add
<script src="http://example.com/aio.js" type="text/javascript"></script>
So the Single File aio.js call all the 3 files.
Thanks in advance.
Here is the Live example..
var element1 = document.createElement("script");
element1.src = "https://code.jquery.com/jquery-2.0.0.min.js";
document.body.appendChild(element1);
console.log(element1)
For you :
Put this code in your http://example.com/aio.js file
window.onload = function() {
var element1 = document.createElement("script");
element1.src = "https://code.jquery.com/jquery-2.0.0.min.js";
document.body.appendChild(element1);
var element2 = document.createElement("script");
element2.src = "http://example.com/jquery.cookie.js";
document.body.appendChild(element2);
var element3 = document.createElement("script");
element3.src = "http://example.com/js.cookie.js";
document.body.appendChild(element3);
}
And in your html file..
<script src="http://example.com/aio.js" type="text/javascript"></script>
Hello I need help in assigning a random number to the src file in a script tag. I have read all the posts I could find, but not making any head way.
so here is what i am trying to do. In the code below, the file referenced by the src tag is myjsfile.1234.js.
What i want to is randomly generate the "1234" every time the page is loaded.
<script data-cfasync="false" id = "myid" src="https://www.example.com/myjsfile.1234.js" type="text/javascript"> </script>
For example I have tried this without success
<script>
var randomnos = Math.ceil(Math.random() * 1000000000);
var mysource = "https://www.example.com/myjsfile."+randomnos+".js";
</script>
<script data-cfasync="false" id = "myid" src=mysource type="text/javascript"></script>
So will appreciate any help I can get
Another way: using Jquery you can use $.getScript()
var randomnos = Math.ceil(Math.random() * 1000000000);
var mysource = "https://www.example.com/myjsfile."+randomnos+".js";
window.onload = function() {
$.getScript(mysource,function(){console.log('loaded')})
}
You need to create script element programatically and append it to html page:
var randomnos = Math.ceil(Math.random() * 1000000000);
var mysource = "https://www.example.com/myjsfile."+randomnos+".js";
window.onload = function() {
var script = document.createElement('script');
script.src = mysource;
document.head.appendChild(script);
}
I have a variable of the form :
var x = '<script type="text/javascript" language="javascript"> ..lots of stuff...</script>
<script type="text/javascript" language="javascript"> ..even more of stuff...</script>'
and I want to insert it with jquery into my HTML code and execute it.
I tried using the append, html and eval without any luck.
Any ideas?
sample script:
<script type="text/javascript" language="javascript">
var clk = 'http://......';
</script>
<script type="text/javascript" language="javascript" src="http://...."></script>
<noscript>
<img src="http://..." width="120" height="600" border="0" alt="">
</noscript>
this will in the end show an img, which will load asynchronously.
Usually having </script> tags nested within other <script></script> tags will break things. You'll need to split them up like in the Javascript below to not cause browser issues.
Here is a working fiddle:
https://jsfiddle.net/2vrfxrse/
Javascript
var jsCode = '<scr' + 'ipt>var executeTest = function(){ alert("This is a test."); }</scr' + 'ipt>';
$('head').append(jsCode);
HTML
<script>executeTest();</script>
This solution will probably work for your specific scenario:
var rx = new RegExp("<script .*?>(.*?)<\/script>", 'g');
var x = '<script type="text/javascript" language="javascript">alert("..lots of stuff...");</script><script type="text/javascript" language="javascript">alert("..even more of stuff...");</script>';
var res = rx.exec(x);
while (res) {
var s = document.createElement("script");
s.appendChild(document.createTextNode(res[1]));
document.body.appendChild(s);
res = rx.exec(x);
}

You can use Jquery getScript:
//Moment example
if (typeof moment == "undefined") {
var url = "~/assets/js/moment.js";
$.getScript(url);
}
Or Jquery Function:
$(function(){
var test = "this.Foo = function() {alert('hi');}";
var F=new Function (test);
(new F()).Foo(); //Shows "Hi" alert
});
$(function(){
var test = "this.Foo = function() {alert('hi');}";
var F=new Function (test);
(new F()).Foo(); //Shows "Hi" alert
});
