小程序可以动态渲染数据吗
我想动态渲染以上数据 ,先采用随机方式取一个数字,然后加到正确的数字 ,采用这样的动态方式
rollData: function (realData, index = 0){ let roundData, randomData; if (index == 0) { roundData = [1, 2, 3, 4, 5, 6, 7, 8, 9]; roundData.splice(roundData.find((item, index) => { if (item === realData[index]) { return index; } }), 1) randomData = roundData[Math.floor(Math.random() * 9)]; } else { roundData = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]; roundData.splice(roundData.find((item, index) => { if (item === realData[index]) { return index; } }), 1) randomData = roundData[Math.floor(Math.random() * 10)]; } this .rollFunc(randomData, realData, roundData, index) }, rollFunc: function (randomData, realData, roundData, index) { let arrData = `letter[${index}]`; console.log(randomData, realData, roundData, index) this .setData({ [arrData]: randomData }) if (randomData == realData[index]) { if (++index === (realData.length-1)) { console.log(33333) return ; } else { this .rollData(realData, index) } } if (++randomData > 9 ){ if (index === 0) { randomData = 1 } else { randomData = 0 } } this .rollFunc(randomData, realData,roundData,index) }, |
以上为自定义方法
this .rollData([1,2,3,4]) |
我在onload调用方法时,发现小程序并没有动态渲染
想问一下怎么实现这个功能呢 万分感谢(´▽`ʃ♡ƪ)
