For example, to store a piece of historical record data, this data has a list attribute which is an array of items, and each item contains an attribute object which is very large, such as base64 media (or other data streams), and this needs to be uploaded again The media in the historical record is transferred to another device. At this time, the media needs to be uploaded again to go through the process again, and the user experience is extremely poor; and the historical record data is copied to form a new historical record, and indexedDB needs to store this copied historical record. , causing the user's disk space to be occupied, and the size of the occupied disk space will increase with the increase of this copy, and the increase speed is very fast

Embodiment 1
[0027] Such as figure 2 As shown, this embodiment provides a data separation storage display method based on indexedDB storage, including:
[0028] Step 1. When multiple media are uploaded, generate a unique ID for each media, and generate a corresponding first media object; the first media object includes media stream attributes and unique ID attributes, and stores the first media object To the indexedDB media storage warehouse;
[0029] Step 2. Separate each first media object to obtain a second media object that does not contain a media stream attribute and has a unique ID attribute, and adds the second media object to the media list array in the historical record object, and the The history object is stored in the indexedDB history storage warehouse;
[0030] Step 3. When a historical record needs to be displayed, search for the corresponding historical record object from the indexedDB historical record storage warehouse, and find the corresponding historical record obj...
Embodiment 2
[0034] Such as image 3 As shown, in this embodiment, a data separation storage display device based on indexedDB storage is provided, including:
[0035] The storage module generates a unique ID for each medium when multiple media are uploaded, and generates a corresponding first media object; the first media object includes a media stream attribute and a unique ID attribute, and stores the first media object To the indexedDB media storage warehouse;
[0036] The separation module obtains the second media object without the media stream attribute and the unique ID attribute by separating each first media object, and adds the second media object to the media list array in the historical record object, and the The history object is stored in the indexedDB history storage warehouse;
[0037] The display module, when a historical record needs to be displayed, searches for the corresponding historical record object from the indexedDB historical record storage warehouse, and sear...

Abstract
The present invention provides a data separation storage display method and device based on indexedDB storage. The method includes: when multiple media are uploaded, a unique ID is generated for each media, and a corresponding media object is generated; the media object includes a media stream attributes and unique ID attributes, and store the media objects in the media storage warehouse; each first media object is separated to obtain a second media object that does not contain media flow attributes and has a unique ID attribute, and adds the second media object To the media list array in the historical record object, store the historical record object in the indexedDB historical record storage warehouse; when a historical record needs to be displayed, find the corresponding historical record object from the historical record storage warehouse, according to the The unique ID attribute of the media object in the history record array, find out the corresponding media object from the media storage warehouse, and display the media stream to the corresponding position on the front page.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a data separation storage display method and device based on indexedDB storage. Background technique [0002] In the absence of server support, web browsers use indexedDB to store data. For example, to store a piece of historical record data, this data has a list attribute which is an array of items, and each item contains an attribute object which is very large, such as base64 media (or other data streams), and this needs to be uploaded again The media in the historical record is transferred to another device. At this time, the media needs to be uploaded again to go through the process again, and the user experience is extremely poor; and the historical record data is copied to form a new historical record, and indexedDB needs to store this copied historical record. , causing the user's disk space to be occupied, and the size of the occupied disk space will increase w...
