If you mean "data" instead of "date" then you are looking for "item" property.
@
Loader {
id: myLoader
source: "someFile.qml"
}

// somewhere else in code
myLoader.item.someProperty // will return the value of "someProperty"
@

yes i know what you said and thank u. but now there is a listview element in B.qml and i wanna use the currentIndex property of listview element of b.qml in A.qml.so using "loader.item.***"can't achieve my goal.and we can't also use "loader.item.listview.currentindex"... am i clear?- -

No. Do you get any error messages? It really should work, but exact details depend on your setup.

...no error message.
and in b.qml,the listview element is not the root item. so "myloader.item.currentIndex"can't work but "myloader.item.mylistview.currentIndex"is illegal...so i dont konw how to deal with it ...

So add an intermediate step:
@
// B.qml
Item {
property int currentIndex: 0

ListView {
id: mylistview
currentIndex: parent.currentIndex
}
}
@

Anod now use myloader.item.currentIndex.

...this means inital a currentIndex to 0 and assign 0 to mylistview.currentIndex.when using"myloader.item.currentIndex",it==0

I don't understand you. With the code above, you can run this in your buttons:
@
onButton1Clicked: myloader.item.currentIndex = 3; // sets the index to 3

onButton2Clicked: myloader.item.currentIndex = 8; // sets the index to 8
