I haven’t written a summary for a long time. Today I will summarize what drag and drop is used recently. Drag and drop is just dragging and dropping to generate code and pages. It is also referred to as a low-code platform. Some relatively large companies will use these words. Let’s go step by step
Let's take a look at the basic page first.
The first is based on element from
Dependency download
1.
npm i element-ui -S2.
npm install vuedraggable --save3.
npm install js-beautify4.
npm install file-saver５.
npm install clipboard --saveThen look at the directory
Then split the directory
