javascript - 具有多个值的表过滤

Question

我有一些数据存储在一个表中，我想使用 Javascript 进行过滤。我在输入字段中键入我的过滤器字符串，并仅显示匹配的行。 但是现在，我想这样做:例如，如果我在筛选字段中键入 value1|value2，我只需要与这两个字符串匹配的行(value1 AND value2)。我已经尝试了很多方法来做到这一点，但没有人完全按照我的意愿去做......

这是我用来过滤的示例(适用于一个字符串):

function filterFromName(text) {

    // Variables
    var filter, tableData, tr, td, i;
    filter = text.toUpperCase();
    tableData = document.getElementById('data_values');
    tr = tableData.getElementsByTagName('tr');

    // For each table row, hide those who don't match the search text
    for (i = 0; i< tr.length; i++) {
        td = tr[i].getElementsByTagName('td')[1]; // query the Alias column
        if (td) {
            if (td.innerHTML.toUpperCase().indexOf(filter) > -1)
                tr[i].style.display = "";
            else
                tr[i].style.display = "none";
        }        
    }

}

有没有办法调整这段代码来做我想做的事？

Answer 1

But now, I would like to do this : for example, if I type "value1|value2" in my filter field, I want only rows which match with these 2 strings (value1 AND value2).

您需要将您的逻辑更改为(内联评论)

function filterFromName(text) {
    var tableData, tr, td, i;
    var filterParams = text.toUpperCase().split( "|" ); //split by | to get array of search parameters
    tableData = document.getElementById('data_values');
    tr = tableData.getElementsByTagName('tr');
    // For each table row, hide those who don't match the search text
    for (i = 0; i< tr.length; i++) {
        td = tr[i].getElementsByTagName('td')[1]; // query the Alias column
        if (td) {
            var tdValue = td.innerHTML.toUpperCase();
            var isMatched = filterParams.filter( function( val ){ return tdValue.indexOf( val ) > -1 }); //check if any val in filterParam array is matching the tdValue
            if ( isMatched.length ) //check length of filtered resultset
                tr[i].style.display = "";
            else
                tr[i].style.display = "none";
        }        
    }
}
