| 一応、ご希望の仕様どおり書いてみましたが、これでよろしいでしょうか。 |
| ```javascript |
| var settings = [ |
| {"id":"category1", ratio:0.7}, |
| {"id":"category2", ratio:0.7}, |
| {"id":"category3", ratio:0.5}, |
| {"id":"category4", ratio:0.5}, |
| {"id":"category5", ratio:0.3}, |
| {"id":"category6", ratio:0.3}, |
| {"id":"category6", ratio:0.2}, |
| {"id":"category7", ratio:0.2}, |
| {"id":"category8", ratio:0.2}, |
| {"id":"category9", ratio:0.2}, |
| ]; |
| console.log( |
| settings.filter( |
| e => e.ratio > Math.random() |
| ).slice( 0, 2 ).map( |
| e => document.getElementById(e.id).value |
| ) |
| ); |
| ``` |
