Closed 2 years ago.
I'm trying to create something that allows people to execute a line of JS. I want to convert the string that people type into a function to execute on the page using the HTML tag
I've looked around and nothing is helping to this.
you can use eval();

eval("console.log('hello')");

How can I get query string values in JavaScript?
(73 answers)

I'm kind of new to javascript and I was wondering if there was a better alternative to slice. I'm currently using window.location.slice at the moment and it feels like I could be using a better alternative. If you've ever used express.js you might have heard of "req.query.id", something like that in raw javascript would be perfect. Thanks, Alek.

I have a javascript variable. I'd like to assign the value of it to JSTL variable.
How can I achieve it?
This is not possible since JavaScript is run in the client browser and JSTL in the server.
Your JavaScript must send the value to a servlet, one way or another.

Is there any way to get its filename by only using javascript?
For example
I want to get the string somefile.js?v=32&b=2.2 inside that same javascript file.
Is it possible to get it without going through the script tag?
Filename using only for loading script text. After that this script text puts in javascript tag and executes.

I am trying to figure out how to get the parts of a URL I am going to be receiving from a third-party website. The URL I am expecting is something like: index.html?lob=company&ZipCode=22407
All of my pages are coded in .html rather than PHP due to my client's needs/desires, so my question is how can I get the "ZipCode" value.
In PHP this would be super simple, however I cannot do that.
Use Javascript instead.
var value_of_zipcode = "index.html?lob=company&ZipCode=22407".match("ZipCode=([0-9]{5})")[1];
now the value_of_zipcode is 22407
