问题 For the first time Im trying to setup a VueJS view with multiple files upload. For now I have this: <input type="file" class="custom-file-input" v-model="images"> <span class="custom-file-control"></span> First of all, do we have good libraries with Vue that solves this ?

问题 Say I wanted to use a custom image or shapefile in an interactive environment (like R Shiny) such as this image of a paper airplane: I would also be willing to draw the image myself in the program to allow for full control. But the overall goal would be to allow a user to drag the edges of the image and the program could keep track of the size of the changes for each dimension (say wingspan of the paper airplane) Would Shiny be a possibility here, or do I need to use another program?

问题 I wonder if it would be possible to manipulate a price calculation that is done on the frontend? I read a lot about JavaScript price calculators with the business logic solely on the client side, but nothing about security.

问题 Hi, I'm about 2 weeks into building my application with ember.js, and the time has come to pull together my project layout into its final shape.

Let's say, I have two manager-like classes

问题 I'm using vis-js timeline library for building a timeline. I need to sort the elements in each group. Groups are like in example here. I saw that I can do this using the " order option in the item" like here but I cannot understand how it works. I tried this way: var groups = new vis.DataSet([ {id: 0, content: 'First', value: 1}, {id: 1, content: 'Third', value: 3}, {id: 2, content: 'Second', value: 2} ]); // create a dataset with items var items = new vis.DataSet([ {id: 0, group: 0, content:

问题 I have a small problem with my VueJS code, in the section "Output : Compressed GS1 Digital Link URI" When there is no result, it should have nothing display like this (I have removed manually) : I think I should put an if statement and only display the result if there is something.
