Debug Information
during:
_loadPdf(src: string) {
this._destroyPdf();
PDFJS.getDocument(src).promise.then(pdf => {
let pageCount = pdf.numPages,
pageCountLabel = '' + pageCount;
this._pdf = pdf;
this._pageCount = pageCount;
this._getPage(this._getDisplayedPageNumber(), true);
(this.$n('toolbar-page-active') as HTMLInputElement).max = pageCountLabel;
this.$n('toolbar-page-total').textContent = pageCountLabel;
this._updateToolbar();
}, err => {
zk.error(err.message);
this._destroyPdf();
this._cleanContent();
});
},
The promise callback can be reached when the component has already been detached.
this cause this.$n('toolbar-page-active') and this.$n('toolbar-page-total') to return null, cause error.
