我正在试图弄清楚如何删除子注释并在相同的parent>child设置中返回array.
现在,在点击注释上的delete按钮时,我运行一个函数,循环遍历父注释,过滤掉与所点击注释ID匹配的父注释,
let filteredComments = [";
function handleClick(e) {
setLoading(true);
for (let i = 0; i < comments.length; i++) {
if (comments[i".id !== Number(e.target.id)) {
filteredComments = [...filteredComments, comments[i"";
}
}
console.log(filteredComments);
// setComments(...comments, filteredComments);
setTimeout(() => {
setLoading(false);
}, 1000);
}
这将返回与上面的原始data.json条注释相同的array.我试图删除的 comments 是id4,并且是一个子 comments .我try 了十几种不同的方法来遍历子 comments ,但我不知道如何只返回与所选 comments id不匹配的子 comments ,并以同样的parent>child
方式返回对象(有一次我让它返回一个数组,其子 comments 紧挨着父 comments ,这会搞砸 comments 到页面的映射).
我try 的最后一件事是循环遍历父注释,将它们推送到过滤数组中,然后循环遍历过滤数组中任何注释的子注释.
let filteredComments = [";
function handleClick(e) {
setLoading(true);
for (let i = 0; i < comments.length; i++) {
if (comments[i".id !== Number(e.target.id)) {
filteredComments = [...filteredComments, comments[i"";
}
}
if (comments[i".replies.length !== 0) {
for (let k = 0; k < comments[i".replies.length; k++) {
if (comments[i".replies[k".id !== Number(e.target.id)) {
filteredComments = [
...filteredComments,
comments[i".replies[k",
";
}
}
}
console.log(filteredComments);
// setComments(...comments, filteredComments);
setTimeout(() => {
setLoading(false);
}, 1000);
}
