toggleStar: function(e) {
console.log('传入函数的e',e);
let index = e.currentTarget.dataset.index;
console.log('当前点击的标签',index)
let item = this.data.ziliaomuluhechengdata[index];
console.log('对应的 ziliaomuluhechengdata[index]', item);
console.log('当前传入的收藏标签',item.shoucang)
if (item.shoucang==false) {
item.shoucang = !item.shoucang; // 直接修改 item 对象中的 shoucang 值为 true
this.setData({
['ziliaomuluhechengdata[' + index + '].shoucang']: item.shoucang
});
console.log('取反收藏标记的数据', this.data.ziliaomuluhechengdata);
app.globalData.ziliaoshoucangjia.push(item);
console.log('全局收藏夹数据', app.globalData.ziliaoshoucangjia);
}
if (item.shoucang==true) {
// 先找到要删除的 item 在全局数组中的索引
const removeIndex = app.globalData.ziliaoshoucangjia.findIndex((value) => value === item);
if (removeIndex!== -1) { app.globalData.ziliaoshoucangjia.splice(removeIndex, 1); }
}
console.log('删除当前收藏后的item数组',app.globalData.ziliaoshoucangjia)
item.shoucang = false; // 直接修改 item 对象中的 shoucang 值为 false
this.setData({
['ziliaomuluhechengdata[' + index + '].shoucang']: item.shoucang
});
console.log('取消收藏标记后的数组',this.data.ziliaomuluhechengdata)
}
这段代码，数组里初始的item.shoucang的值都为false。无论我把代码改成两个if。还是if else 还是if else if。它都同时执行了两个逻辑分支，似乎程序在这里，无论怎么修改判断，无论怎么修改语句都像是同时具备了false和true两个矛盾的属性
