Question

我正在创建一个搜索，用户可以在多个列中进行搜索。

我使用jQuery :contains实现了搜索单列，但没有获得如何进行多列搜索？

CODE：

<table border="1" cellpadding="10">
<tr style="background:#428bca; color:#fff;">
  <th>Name</th>
  <th>Number</th>
</tr>
<tr>
  <td>
    <input type="text" onkeyup="search('name', this.value);" />
  </td>
  <td>
    <input type="text" onkeyup="search('number', this.value);" />
  </td>
</tr>
<tr>
  <td class="search_name">abcd</td>
  <td class="search_number">12345</td>
</tr>
<tr>
  <td class="search_name">abcd</td>
  <td class="search_number">67890</td>
</tr>
<tr>
  <td class="search_name">ijkl</td>
  <td class="search_number">00000</td>
</tr>
<tr>
  <td class="search_name">mnop</td>
  <td class="search_number">00000</td>
</tr>
</table>

Java Script Code Here：

function search(field, val) {
      if (val.length > 1) {
        $('.search_name').parent('tr').hide();
        $.expr[":"].contains = $.expr.createPseudo(function(arg) {
          return function(elem) {
            return $(elem).text().toUpperCase().indexOf(arg.toUpperCase()) >= 0;
          };
        });
        if (field == 'name') {
          $('.search_name:contains(' + val + ')').parent('tr').show();
        }
        if (field == 'number') {
          $('.search_number:contains(' + val + ')').parent('tr').show();
        }
      } else {
        $('.search_name').parent('tr').show();
      }
    }

从上面的代码中，它一次只搜索单个列，但我想要name abcd 中的搜索词，number 12345 ，所以比它只显示与两个关键字匹配的一行。
