I’m trying to download jQuery into my document via my JavaScript file. When I do document.write, however, the "https://" is marked as a comment.
function downloadjQuery() {
document.open();
document.write("<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>");
document.close();
}
In your code, you use four same quotes in the string, so JavaScript thinks your string ends there:
"<script src="
I recommend use ' instead of double quotes, or you can use \' or \", also you can use `, some examples:
let Hello = "How 'are' you?"
let World = "How \"you\" did this?"
let Search = 'Searching for \'free mincraft 2022\'...'
let User = `
Hey "there", 'somewhere else'!
`
So try this out:
function downloadjQuery() {
document.open();
document.write("<script src='https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js'></script>");
document.close();
}
You're using double quotes and single quotes wrong.
You can try to escape double quotes with \"or use single quotes '.
This line is wrong:
"<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>"
It gets read as "<script src=" https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js "></script>"
Your quote use is incorrect. You closed the quotes before the link.
Instead of:
document.write("<script src="link"></script>");
You should do:
document.write("<script src='link'></script>");
When you have to use quotes multiple times, you can also use ' instead of " four times.
Also, if you want to keep the raw version of the comment, you can type \ before //.
Example:
(Correct Usage)
\//I printed a raw version of a comment.
(Incorrect Usage)
//I did not print a raw version of a comment.
