Why does GC not clear the Dialog references?


Why does GC not clear the Dialog references?

like below fixes the issue If I understand your screenshot correctly, all the referents are weak, so eventually it will get GCd. But there are no guarantees about when it will GCd; typically it won't happen immediately. You can try to hurry up GC by running the garbage collector (System.gc()), but there are still no guarantees whether it will collect all the garbage or not.

wish helps you You're using $.load() wrong: you shouldn't load a full web page (with , and ) with it, only the piece of HTML that you need. Strip dialogtest1a.html down to just the content you want to place inside the dialog.
If for some reason you have to have a full web page inside the dialog, use an iframe to contain the second document.

this one helps. This is what a std::shared_ptr is for. When you create a shared_ptr as long as one reference exist the memory will still be valid. Here is a little example of using a shared pointer:
code :
#include <iostream>
#include <memory>

void use_shared_ptr(std::shared_ptr<int> sp)
{
    std::cout << "in use_shared_ptr() count is: " << sp.use_count() << std::endl;
}

std::shared_ptr<int> function_that_returns_a_local_object()
{
    auto foo = std::make_shared<int>(42);
    std::cout << "just created shared_ptr.  count is: " << foo.use_count() << std::endl;
    use_shared_ptr(foo);
    std::cout << "after use_shared_ptr(foo) count is " << foo.use_count() << std::endl;
    return foo;
} // oh no.  foo gets destroyed here.  what is going to happen?

int main() 
{
    auto bar = function_that_returns_a_local_object();
    std::cout << "back in main count is: " << bar.use_count() << std::endl;
}
just created shared_ptr.  count is: 1
in use_shared_ptr() count is: 2
after use_shared_ptr(foo) count is 1
back in main count is: 1

seems to work fine You can use one of the opening/closing events:
md-opened md-closed
code :
<md-dialog ... @md-opened="myOpenMethod" @md-closed="myCloseMethod">
new Vue({
  ...
  methods: {
    myOpenMethod() { console.log('opened'); },
    myCloseMethod() { console.log('closed'); }
  },
  ...
})
data() {
  return {
    ...
    uploadDialogKey: 1
  }
},
<upload-dialog :key="uploadDialogKey"></upload-dialog>
openUploadDialog() {
  this.uploadDialogKey++;              // <=== added this line
  this.$refs.uploadDialog.open();
},

I hope this helps . When the button is clicked, 2 sets data is added. I use material design. , This should work:
code :
var element = document.getElementById("producttable")
while (element.lastChild) {
    element.removeChild(element.lastChild);
}
