Fiddle: http://jsfiddle.net/svwa79pe/1/ What I want to do is show three button states depending on whether the

问题 Is this possible to change dynamically publicPath for vue application (in vue.config)? This means that I want to set public path be dynamically depends on real url(some domain), e.g. i want to make only one build, but use it for staging and prod env (and use different cdn-s for assets in different countries, etc). I find that webpack_public_path aims at setting at runtime the public path. But how can I use webpack_public_path with vueJS(vue-cli)? webpack_public_path - didn't work for me.

How to use Vue bound data in Highcharts?

大城市里の小女人 提交于 2021-02-07 08:26:26
问题 I have a chart which axis contents and data will change with time. This happens in a Vue framework. My idea was to use setData() and setCategories() to give the chart pointers to data which will be dynamic. This does not work: when data is updated, the chart is not. The example is in Codepen.io and reproduced below for reference. Please note that this hangs my browser (but the codepen version is OK) new Vue({ el: "#app", data: { config: { chart: { type: 'heatmap' }, series: [{}] }, src: ['a',
