Js – Intercepts the file name or path in the file path

Because it’s a little program, I’m using setData

annex = "zzzy_visa/web/uploads/20210108/aaa.png"
let pos = options.annex.lastIndexOf("/") //'/ last position '
let str = options.annex.substr(pos + 1) // Intercepts the file name string
url = name.substr(0,pos)  // Intercepts the path string
this.setData({
   upload_template: JSON.parse(options.upload_template),
   annex: str
})

//=>aaa.png zzzy_visa/web/uploads/20210108
Copy the code
