Javascript 制表器-基于另一制表器的过滤

我有一个包含搜索结果的制表器。代码如下：

var table = new Tabulator("#json-table", {
    layout:"fitDataFill",
    //initialFilter:[{field:"title", type:"!=", value:"ignoreList.title"}],
    ajaxURL:tabUrl,
    ajaxResponse:function(url, params, response){
        return Object.values(response);
    },
    columns:
        [{title:"Title", field:"title", align:"center"},
        {title:"Price", field:"price", align:"center"},
        {title:"Shipping Cost", field:"shippingCost.shippingServiceCost.value", align:"center"},
        {title:"Watch List", align:"center", cellClick:function(e, cell){
            var data = cell.getData();
            watchListArray.push(data);
            localStorage.setItem("watchList", JSON.stringify(watchListArray));
    },},
        {title:"Ignore List", align:"center", cellClick:function(e, cell){
            var data = cell.getData();
            ignoreListArray.push(data);
            localStorage.setItem("ignoreList", JSON.stringify(ignoreListArray));
    },
        },
        {title:"Image", align:"center"},
    ],
});

ignoreListArray = JSON.parse(localStorage.getItem("ignoreList"));

var ignoreList = new Tabulator("#json-table", {
    data:ignoreListArray,
    layout:"fitDataFill",
    columns:
        [{title:"Title", field:"title", align:"center"},
        {title:"Price", field:"price", align:"center"},
        {title:"Shipping Cost", field:"shippingCost.shippingServiceCost.value", align:"center"},
        {title:"Watch List", align:"center"},
        {title:"Ignore List", align:"center"},
        {title:"Image", align:"center"},
        ],
    });

我还有一个包含忽略列表的制表器。代码如下：

var table = new Tabulator("#json-table", {
    layout:"fitDataFill",
    //initialFilter:[{field:"title", type:"!=", value:"ignoreList.title"}],
    ajaxURL:tabUrl,
    ajaxResponse:function(url, params, response){
        return Object.values(response);
    },
    columns:
        [{title:"Title", field:"title", align:"center"},
        {title:"Price", field:"price", align:"center"},
        {title:"Shipping Cost", field:"shippingCost.shippingServiceCost.value", align:"center"},
        {title:"Watch List", align:"center", cellClick:function(e, cell){
            var data = cell.getData();
            watchListArray.push(data);
            localStorage.setItem("watchList", JSON.stringify(watchListArray));
    },},
        {title:"Ignore List", align:"center", cellClick:function(e, cell){
            var data = cell.getData();
            ignoreListArray.push(data);
            localStorage.setItem("ignoreList", JSON.stringify(ignoreListArray));
    },
        },
        {title:"Image", align:"center"},
    ],
});

ignoreListArray = JSON.parse(localStorage.getItem("ignoreList"));

var ignoreList = new Tabulator("#json-table", {
    data:ignoreListArray,
    layout:"fitDataFill",
    columns:
        [{title:"Title", field:"title", align:"center"},
        {title:"Price", field:"price", align:"center"},
        {title:"Shipping Cost", field:"shippingCost.shippingServiceCost.value", align:"center"},
        {title:"Watch List", align:"center"},
        {title:"Ignore List", align:"center"},
        {title:"Image", align:"center"},
        ],
    });

如果用户单击要忽略的行的“忽略列表”单元格，我将使用

localStorage

将搜索结果中的行存储在“忽略列表”列表器中。如果一行被放在忽略列表中，我想让它在将来的搜索结果中永远不会出现，直到它从忽略列表中删除

是否有内置的筛选功能可以帮助我完成这项工作？

您需要使用自定义筛选功能来完成这项工作

为了过滤掉这些行，您需要一种方法来比较ignore列表中的行和表中的行。通常，您会为每一行分配一个id字段，然后检查该行的id是否在忽略列表中。我将在示例中使用这种方法，但您可以轻松地调整它，以查找行对象中任何属性的匹配值

在自定义过滤器中，我们将使用JavaScript数组中内置的过滤器函数查找数组中的任何匹配项

function customFilter(data, filterParams){
    //data - the data for the row being filtered
    //filterParams - params object passed to the filter

    //check for matches
    var matches = ignoreListArray.filter(function(element){
        return element.id == data.id
    });

    return !matches.length; //allow row if it does not match any row in the ignore list
}

//set filter on table
table.setFilter(customFilter);
