I see what’s happening is. This is a classic example of an “Uncawght ReferenceError: web3 is not defined” error.
Here’s the correced code:
`javascript
The
window.onload = function() {
if (typeof window.web3 === 'undefined') {
st new Error('web3 is not defined');
}
}
`
Let me explain what's going on:
- window
refers to the global object in a web page.
- web3
is an obed that provides accesses to the Ethereum blockchain. It's not explicitly imported into the script, it is, called "undefined".
- The conditiontypeof.web3 === ‘undefined” If not, it’s a new error without a message indication that
web3
is not defined.
In this correced version:
–
- Inside the
if
stement, we check iftypeof window.web3 ==== 'undefined'. If it's True, a new error is a decreptive message.
- Instaed of triing to callweb3.min.js`, we directly the error.
This code it is prevent the “Uncaugt ReferenceError: web3 is not defined” error from occurring in the firt place.
