2022-03-21 - picker组件手机端设置value值混乱?
picker组件 mod=multiSelector时,开发工具没问题,手机端设置value的值无效。 [图片] 三列联动选择器。当选择最后一列时,设置了前两列的index值。在开发工具中没问题,但是手机端无效,选择第二列也是无效。 bindMultiPickerColumnChange: function (e) { console.log('修改的列为', e.detail.column, ',值为', e.detail.value); let multiIndex = this.data.multiIndex; //picker组件value属性的值 let multiArray = []; //picker组件range属性的值 let areaData = this.data.areaData; //自定义的地区数据 multiArray[0] = [empty,...areaData]; multiIndex[e.detail.column] = e.detail.value; if(e.detail.column == 0){ let index1 = e.detail.value > 0 ? e.detail.value-1 : 0; multiArray[1] = [empty,...areaData[index1]['children']]; //empty为自定义的对象,目的是当选择时显示全部 multiArray[2] = [empty['children'][0],...areaData[index1]['children'][0]['children']]; multiIndex[1] = 0;//第二列的index multiIndex[2] = 0;//第三列的index }else if(e.detail.column == 1){ let index = multiIndex[0]; let index1 = index == 0 ? 0 : index-1; let eValue = e.detail.value == 0 ? 0 : e.detail.value-1; multiArray[1] = [empty,...areaData[index1]['children']]; multiArray[2] = [empty['children'][0],...areaData[index1]['children'][eValue]['children']]; //直接选择第二列时,第一列自动选择对应的上级地区 let index2 = index == 0 ? 1 : index; multiIndex[0] = index2; multiIndex[2] = 0; }else{ let index = multiIndex[0]; let index1 = multiIndex[1]; let index2 = index > 0 ? index-1 : 0; let index3 = index1 > 0 ? index1-1 : 0; multiArray[1] = [empty,...areaData[index2]['children']]; multiArray[2] = [empty['children'][0],...areaData[index2]['children'][index3]['children']]; //直接选择第三列时,第一、二列自动选择对应的上级地区 let index4 = index == 0 ? 1 : index; let index5 = index1 == 0 ? 1 : index1; multiIndex[0] = index4; multiIndex[1] = index5; } this.setData({ multiArray:multiArray, multiIndex:multiIndex, }); },
