Js操作Array数组

Posted 2021-01-24 奈何缘浅丶世俗沾染了无奈

 

之前写过一篇文章，但是很模糊，不过却给我提供了一个思路，所以没有删除，这次写的是一个完善版本！

因为在很多的时候我们在选中了几行数据，然后存放在Array中，如下图：

 

看下控制台的数据

 

我双击了这两个项目

然后我们看看控制台的数据：

数量已经加1了，代码如下：

var _historyData = new Array();
function BindGoodsTab(goodsId, goodsName, goodsPrice) {
    var _html = "";
    var _data = {};
    _data["id"] = parseInt(goodsId);
    _data["GoodsName"] = goodsName;
    _data["GoodsNum"] = 1;
    _data["GoodsPrice"] = parseFloat(goodsPrice);
    var _len = _historyData.length;

    var _Ishave = false;
    var _flag = 0;
    if (_historyData.length > 0) {
        for (var i = 0; i < _len; i++) {
            var _hGid = parseInt(_historyData[i]["id"]);
            if (_data["id"] == _hGid) {
                _flag = i;
                _Ishave = true;
                break;
            }
        }
        console.log(_flag);
        if (!_Ishave) {
            _historyData.push(_data);
        }
        else {
            _historyData[_flag]["GoodsNum"] = parseInt(_historyData[_flag]["GoodsNum"]) + 1;
        }
    }
    else {
        _historyData.push(_data);
    }
    console.log(_historyData);
    $("#goodsList").html(_html);
}

 删除某一个对象：如下图

控制台：

 

 代码：

function DelLease(goodsId) {
    for (var i = 0; i < _historyData.length; i++) {
        if (goodsId == _historyData[i]["id"]) {
            _historyData.splice(i, 1);
        }
    }
    CreateLeaseTab(_historyData);
}

function CreateLeaseTab(_historyData) {
    var _html = "";
    var _totalMoney = 0;
    for (var i = 0; i < _historyData.length; i++) {
        _html += "<tr style=\'border-top:1px solid #ccc;\'>";
        _html += "<td  style=\'width:160px;padding:7px 0px;\'>" + _historyData[i]["GoodsName"] + "</td>";
        _html += "<td  style=\'width:60px;\'>" + _historyData[i]["GoodsNum"] + "</td>";
        _html += "<td  style=\'width:100px;\'>" + _historyData[i]["GoodsPrice"].toFixed(2) + "</td>";
        _html += "<td  style=\'width:100px;\'>" + _historyData[i]["GoodsTotalPrice"].toFixed(2) + "</td>";
        _html += "<td  style=\'width:100px;\'><img src=\'../images/Gift/del.png\' onclick=\'DelLease(" + _historyData[i]["id"] + ")\' /></td>";
        _totalMoney += parseFloat(_historyData[i]["GoodsTotalPrice"].toFixed(2));
    }
    $("#goodsList").html(_html);
    $("#totalMoney").html(_totalMoney.toFixed(2));
    console.log(_historyData);
}
