javascript - 使用javascript创建循环来删除pdf中的书签

Question

我试图删除大量不必要的低级书签。 for 循环仅返回最后一个较低级别的书签，我不知道为什么。我有下面使用的代码:

// Calling the bookmarks
var bm = this.bookmarkRoot; 

//getting the length of the lower level bookmarks
var bmlength = bm.children[0].children[0].children.length; 

// attempting to gather all the bookmarks to delete
for (var i=0; i < bmlength; i++){
var removeMe=bm.children[0].children[0].children[i];
}
removeMe.remove() 

<!-- Please replace me with example HTML -->

Answer 1

试试这个

for (var i=0; i < bmlength; i++){
   var removeMe=bm.children[0].children[0].children[i];
   removeMe.remove() 
}

或者这个

for (var i=0; i < bmlength; i++){
   bm.children[0].children[0].children[i].remove();
}
