Method for obtaining webpage loading first screen time delay

Abstract

The invention discloses a method for obtaining webpage loading first screen time delay, and belongs to the field of network and service testing. The method comprises the following steps of: firstly, obtaining and presetting the layout of a target website; finishing downloading resources on a html (Hypertext Markup Language), injecting a js (JavaScript) code at the beginning of the resource loading of the webpage of the target website while document.readState is already under an interactive state, carrying out polling checking to calculate whether a resource element loaded in a current webpage is loaded and displayed within a first screen range or not; and once first-screen resources conform to the layout and finish being loaded, calculating the time delay from time when a user requests a webpage to now, and recording as the first screen time delay. Compared with the prior art, the method is simple in operation, the user only needs to click the function button to carry out a test without other complex operations, and power consumption is low. The method only needs a simple script program to be operated, extremely low cpu and memory resources are occupied, other power consumption hardware is not used, the user does not feel the execution of the method. The method has the advantages of being high in calculation speed, safe, reliable, high in universality, wide in applicability and easy in large-range popularization.

Description

technical field [0001] The invention relates to the field of network optimization testing, and more specifically, the invention relates to a method for obtaining the time delay of loading the first screen of a webpage. Background technique [0002] Under the existing network status, users often encounter problems and troubles such as bandwidth congestion, low application performance, worms, DoS, and malicious intrusions that have a negative impact on network usage and resources. The network optimization function is aimed at the existing Firewall, security and intrusion detection, load balancing, bandwidth management, network anti-virus and other equipment and network problems can be supplemented, and parameters can be collected and data analyzed by accessing hardware and software operations to find out the reasons that affect network quality. Through technical means or adding corresponding hardware equipment and adjusting the method to make the network reach the best operati...

Problems solved by technology

With the improvement of mobile network bandwidth and the continuous popularization of mobile phone users' data usage, operators need to measure the fluency of the network and web pages from the perspective of users, and the most intuitive and important thing in web pages is the first screen display delay (ie The delay that users see and can operate), and this delay directly reflects the user's subjective perception of the fluency of the general website, which cannot be obtained directly by using ordinary terminals to capture packets or the network side, so that this indicator cannot be simply and effectively quantified and analyze

[0005] The current first screen delay method is to compare and analyze images by taking screenshots. This method has great limitations. Once the website content is changed, the sample image needs to be replaced to ensure normal operation; and the screenshot method is complicated to operate on the mobile phone and consumes power. High, low accuracy, therefore, not suitable for large-scale promotion
