本地存储index.js cordova

Question

I am following the cordova tutorial on tutorialpoints.com.

At Step 2 Adding Event Listeners to set and show local storage there is a sentence which is not easily comprehended by me precisely at: "Cordova security policy doesn't allow inline events so we will add event listeners inside index.js files."

What is that supposed to mean? Where should I put these inside the index.js?

document.getElementById("setLocalStorage").addEventListener("click", setLocalStorage);
document.getElementById("showLocalStorage").addEventListener("click", showLocalStorage);
document.getElementById("removeProjectFromLocalStorage").addEventListener("click", removeProjectFromLocalStorage);
document.getElementById("getLocalStorageByKey").addEventListener("click", getLocalStorageByKey);

var localStorage = window.localStorage;`

Inside variable app but outside the functions, or inside any of the functions?

It is driving me crazy!!!!

Answer 1

You should put it in document redy like

  document.addEventListener("DOMContentLoaded", function(event) {
document.getElementById("setLocalStorage").addEventListener("click", setLocalStorage);
document.getElementById("showLocalStorage").addEventListener("click", showLocalStorage);
document.getElementById("removeProjectFromLocalStorage").addEventListener("click", removeProjectFromLocalStorage);
document.getElementById("getLocalStorageByKey").addEventListener("click", getLocalStorageByKey); 
}
