我是JQuery的新手。我在HTML下方：

   <label for="filter">Store Name:</label>
   <select class="filter" data-tableId="table1" onchange="testFilter()">

并使用下面的JQuery函数根据列文本过滤记录，但不能根据商店名称过滤记录：

<script>
function testFilter(){
$(".filter").change(function() {
    var filterValue = $(this).val();
    var row = $('.record'); 
      console.log(filterValue);
    row.hide()
    row.each(function(i, el) {
         if($(el).children().innerHTML == filterValue) {
             $(el).show();
         }
    })   
});
}
</script>

对您的代码进行了一些更改。

为了使您的过滤器更好，您需要将select ddl的值保持与表（.store）的值相同。

United Kingdom != united_kingdom 

function testFilter(obj) { 

// removed .change because this method is already invoking on onchange

  var filterValue = $(obj).val(); 
  var row = $('.record');
  console.log(filterValue);
  row.hide()
  row.each(function(i, el) {

    if (

    $(el).text().toUpperCase().indexOf(filterValue.toUpperCase()) > -1 

    // used .text(), because .innerHTML will return nodes as well
    // whole content can't be same, so checked index of selected filter word
    // You can add .find('.store') if you want to make search in only store column
    // .toUpperCase() will maintain accuracy for sentence case. cause 'denmark' == 'Denmark' will return false
      ) {
      $(el).show();
    }
  })

}


function testFilter(obj) { // removed .change because this method is already invoking on onchange
  var filterValue = $(obj).val(); 
  var row = $('.record');
  console.log(filterValue);
  row.hide()
  row.each(function(i, el) {
    // used .text(), because .innerHTML will return nodes as well
    if (
$(el).text().toUpperCase().indexOf(filterValue.toUpperCase()) > -1 // whole content can't be same, so checked index of selected filter word
) {
      $(el).show();
    }
  })

答案 1 :(得分：1)

这是因为select中的选项值与表中的字段不对应。我对您的js代码进行了一些改进：

  // I removed onchange property of your select 
  // because change event is already attached in this code
  $(".filter").change(function() {
      var translatedFilterValue = getTranslatedFilterValue($(this).val());
      var rows = $('.record'); 

      rows.each(function(i, el) {
           if(translatedFilterValue == 'all' || ($(el).find('.store').text() == translatedFilterValue)) {
               $(el).show();
           } else {
               $(el).hide();
           }
      })   
  });

  //
  // Translates text from select to corresponding values in table
  // for example: from "United States" to "united_states"
  //
  function getTranslatedFilterValue(filterValue) {
    filterValue = filterValue.toLowerCase();

    return filterValue.replace(' ', '_');
  }

$(el).children().innerHTML正在查看整行的所有文本。那将不匹配您的字符串。其他发行值有上限，表格中的值没有上限。有下划线，但没有下划线。

您不应内联onchange事件，而应将onchange绑定到带有jQuery的该元素。

该代码已注释。

$(".filter").change(function() {
  var filterValue = $(this)
    .val()  // get the value of the select
      .toLowerCase()  // normalize it
        .replace(/\s/g,'_');  // replace the spaces
  var rows = $('.record');  // grab all the rows
  rows.show();  // show them
  if (filterValue !== 'all') {  // if we have all, than skip this
    rows
      .find("td.store")  // find the store tds
        .filter(function() {  // loop over read the text and see if it does not match the filter value
          return this.textContent.toLowerCase().trim() !== filterValue
        })
          .parent()  // find the trs
            .hide()  // hide the table rows that do not match
  }
