使用Jquery进行条件突出显示

时间：2017-08-16 08:06:02

标签： javascript jquery css

在此示例https://jsfiddle.net/erv79u0w/中，单击“全选”时，表中将突出显示所有相应的值。

是否可以突出显示 ONLY 表中同一行中存在的值。例如，使用“全选”选择时的第一个值（A，B，X，Y），只应突出显示在同一行中的值。在这种情况下，它只是表格的第二行。因此，只应突出显示第二行的值。

  

同一行中的单元格不不应突出显示，如下图所示。

$('.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').removeClass("highlight").filter(function() {
    return $.inArray($(this).text(), checked) >= 0
  }).addClass("highlight")
  if ($(this).is(".selector"))
    $('.all').not(this).prop("checked", false)
}
.highlight {
