This article mainly introduces "the impact of vue asynchronous data on page rendering". In daily operation, I believe that many people have doubts about the impact of vue asynchronous data on page rendering. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts about "the impact of vue asynchronous data on page rendering". Next, please follow the editor to study!
A problem encountered today is to make sure that the data requested before the page is rendered has been obtained.
Because the user is saved in session after the asynchronous request, and there is no user in the session when the page is rendered, the page reports an error directly.
So I hope to render the page after all the requests have been received.
1. First, div with id as app is hidden with vmurifs = "appShow", and appShow is defined as false to avoid rendering.
two。 Write the counter and query every 1ms. If there is already a user in the session, delete the filter, remove the filter cloth, appShow is true, and start rendering the page, which ensures the normal rendering of the page.
The specific code is as follows:
Created:function () {let that = this let timeTerval = setInterval (()) > {if (sessionStorage.user) {clearInterval (timeTerval); that.appShow = true;// rendering app var removeLoad = document.getElementById ("loading") removeLoad.style.display = "none"} else {console.log ("1222")}, 1);}, at this point, the study on "the impact of vue asynchronous data on page rendering" is over, hoping to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
