dynamic

问题 I'm using type() to dynamically generate classes that will ultimately be pickled. The problem is that the un-pickling process needs the definition of the class in order to re-construct the object that has been pickled. This is where I'm stuck. I don't know how to somehow provide the unpickler a way to generate an instance from a class that was dynamically generated. Any hints appreciated. Thanks! Here's an example of the problem: >>> class Foo(object): ... pass >>> g=type('Goo',(Foo,),{'run'

问题 I have a list of captions displayed from json. I would like to also map the location to local images / or urls in that same json data. So that each iteration of displayed item has its own images included. The problem is with require js which seems to be working only when im passing into it actual string with location of image. If im trying to pass a reference to node in json that holds the location of that image it does not work. note: some html tags are from materialize. Does work: const

问题 I am making sort of a script to show different content everyday with a different image and title. I already got the image loop to show every day a different picture but I need help to do the same with the title. It is for making like a dynamic page of a discount deals which is different every day but repeats itself after one week so I only need to have 7 pictures and 7 titles to show. Here is my code for only the loop of the images every day. var dailyPhotos; var today, img; dailyPhotos =

问题 A problem is occurring with the angular materials mat-stepper when working with dynamic forms. For example I have a stepper with 3 steps each having there own form. The first step however uses a hidden form to determine if it is valid or not as this step can dynamically add more forms so binding all of them to the step is impossible. When you are on the first step you can create multiple forms and everything works as expected without any random validation occurring to the new forms added. The
