When multiple routes are multiplexed with the same template, the template is not re-mounted when switching between these routes. For this situation, we need to listen to the route in the current logic, update the corresponding property when the change occurs, and satisfy the requirement.However, in the implementation process you will encounter the following situations: Shows that the prop attribute that was transferred to El-table when the page was switched has changed, but the inner loop bindin

First, when you need to inject a large section of HTML tags to the page, you should use server rendering (HTML tags from the server loading)
This method places the template on the server using the XMLHttpRequest object to get the external label (for example, multi-page applications)
function Loaddialog (name, oncomplete) {
var xhr = new XMLHttpRequest ();
Xhr.open (' Get ', '/js/dialog/' +name, true);
Xhr.onreadystatechange = function () {
if (xhr.readystate = = 4 xhr.status =) {
