2022/05/26 js数组按照flag，重组成想要的数组

目的：将doneFlag为false的数据展示在数组前面

<script>
    let targetList = [
        {
            itemId: 1,
            doneeAddr: '1111111',
            doneFlag: false
        },
        {
            itemId: 2,
            doneeAddr: '222222',
            doneFlag: true
        },
        {
            itemId: 3,
            doneeAddr: '333333',
            doneFlag: true
        },
        {
            itemId: 4,
            doneeAddr: '444444',
            doneFlag: false
        },
        {
            itemId: 5,
            doneeAddr: '55555',
            doneFlag: true
        },
    ]

    // 思路2，把里面所有为false的摘出来，然后变成两个数组，一个全false，一个全true。在进行拼接
    let undoneList = [];
    let doneList = [];
    targetList.forEach((item, index) => {
        if (item.doneFlag === false) {
            // targetList.splice(index, 1)
            undoneList.push(item)
        } else {
            doneList.push(item)
        }
    })
    console.log('undoneList', undoneList);
    console.log('doneList', doneList);

    let newList = undoneList.concat(doneList);
    console.log('newList', newList);

</script>
