javascript - 在 table 上用几种颜色突出显示

Question

我之前曾就这项工作寻求过帮助，但我意识到我犯了一个错误。所以在这里我有一个工作代码来切换表格上所选值的突出显示颜色。我可以用这段代码改变突出显示的颜色，但我不能同时用不同的颜色突出显示不同的值。这是一个 fiddle 示例:https://jsfiddle.net/vvhbvdyj/和 jquery 代码如下。如果有人可以帮助我，我会很高兴。谢谢。

// JavaScript Document
$(document).ready(function() {

  $('.selector').each(function() {
    $(this).on('click', check);
  });
  $('.all').each(function() {
    $(this).on('click', all);
  });

  function all(event) {

    if ($(this).is(':checked')) {
      $("input:checkbox:not(:checked)", $(this).parents('form')).not(this).prop("checked", "checked");
    } else {
      $("input:checkbox(:checked)", $(this).parents('form')).not(this).prop("checked", "");
    }

    //$('.selector').prop("checked", this.name === "SelectAll");

    check(event);
  }

  function check(event) {
    var checked = $(".selector:checked").map(function() {
      return this.name
    }).get()
    $('td').css('background', '#fff').filter(function() {
      return $.inArray($(this).text(), checked) >= 0
    }).css('background', $('#nextColor').val())
    if ($(this).is(".selector"))
      $('.all').not(this).prop("checked", false)

  }


  $("#Hidden").on("click", function() {
    $(".selector").toggle();
  });


});

如果我没猜错，您想用当前颜色突出显示所选值，而不更改先前所选值的颜色。

在这种情况下，每次单击 checkbox 时，您都应该将当前颜色传递给 che check 函数。通过一些修改，您的代码将如下所示:

$(document).ready(function() {

    $('.selector').each(function() {
        $(this).on('click', function(e) {
            check($(this).prop("checked") ? $("#nextColor").val() : '#fff', $(this).attr("name"));
        }); 
    });
    $('.all').each(function() {
       $(this).on('click', all); 
    });

    function all(event) {
        if ($(this).is(':checked')) {  
            let checked = $("input:checkbox:not(:checked)", $(this).parents('form')).not(this);
            checked.prop("checked", true);
            check($("#nextColor").val(), ...checked.map((i, e) => e.name).get());
        } else {
            let checked = $("input:checkbox(:checked)", $(this).parents('form')).not(this);
            checked.prop("checked", false);
            check('#fff', ...checked.map((i, e) => e.name).get());
        }
    }

    function check(color, ...elements) {
        $('td').each((i, td) => {
            if (elements.includes($(td).text())) $(td).css('background', color);
        });
    }
 

});
