我有一个关于引用对象副本的问题
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
/////////// object Create
let a = {
"0": {
"sortPluginSettings": {
"columnSortType": "numeric",
"sortingOrder": "noSort"
}
}
}
let b= Object.create(a)
console.log("a: ",a)
console.log("b: ",b)
b["0"].sortPluginSettings.sortingOrder="ascending"
console.log("NEWa: ",a) // OOPs mutated
console.log("NEWb: ",b[0])
/////////// object assign
let c = {
"0": {
"sortPluginSettings": {
"columnSortType": "numeric",
"sortingOrder": "noSort"
}
}
}
let e= Object.create(c)
console.log("c: ",c)
console.log("e: ",e)
e["0"].sortPluginSettings.sortingOrder="ascending"
console.log("NEWc: ",c) // OOPs mutated
console.log("NEWe: ",e[0])
</script>
