基于列的数据表搜索 [英] Datatable search based on columns
本文介绍了基于列的数据表搜索的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有数据表，并基于全部和列进行搜索。此处一切正常，但在搜索下拉列表中，表未刷新。例如：我在下拉菜单中选择了名称，然后在右侧搜索文本框中输入了一些内容。它可以进行搜索，但是如果我在搜索过程中从下拉菜单中选择了其他选项，则会显示以前的选择，而不是刷新表格。以下是我的代码。
I have datatables and search based on All and columns. Here everything is fine but in search dropdown selection, table is not refreshing. For ex: I selected 'Name' on dropdown and typed something on right side search textbox..it can able to search but if I select other option from dropdown in the middle of search, previous selection is showing instead refreshing the table. Below is my code.

Javascript（请放在表格下方）
Javascript (please put it below table)
var table = $('#example').DataTable({
dom : 'l<"#add">frtip'
})
$('<label/>').text('Search Column:').appendTo('#add')
$select = $('<select/>').appendTo('#add')
$('<option/>').val('All').text('All').appendTo($select);
$('<option/>').val('0').text('Seq').appendTo($select);
$('<option/>').val('1').text('Name').appendTo($select);
$('<option/>').val('2').text('Position').appendTo($select);
$('<option/>').val('3').text('Office').appendTo($select);
$('<option/>').val('4').text('Start Date').appendTo($select);
$('<option/>').val('5').text('Salary').appendTo($select);
$('input[type="search"]').on( 'keyup change', function () {
var searchValue = $(this).val();
var columnSearch = $select.val();
if(columnSearch == 'All'){
table.search(searchValue).draw();
} else {
table.columns(columnSearch).search(searchValue).draw();
}
});
推荐答案
代码有些错误。
- 没有用于菜单更改的侦听器，因此除非用户在搜索输入中键入其他内容，否则不会发生重绘
-
val（）的值与列索引不匹配-因此您将在错误的列上进行搜索。 - 上一列搜索未清除，因此您将添加到上一搜索中，而不是替换它们。
- There isn't a listener for the change of the menu, so no redraw can occur until the user types something else in the search input box.
- The
val()values don't match the column indexes - so you'll be searching on the wrong columns. - The previous column searches aren't being cleared, so you'll be adding to the previous searches rather than replacing them.
所有都很容易修复，请参见实时示例此处 ，它使用以下代码：
All easily fixable, see the live example here, which uses the following code:
var table = $('#example').DataTable({
dom: 'l<"#add">frtip'
});
$('<label/>').text('Search Column:').appendTo('#add');
$select = $('<select/>').appendTo('#add');
$('<option/>').val('All').text('All').appendTo($select);
$('<option/>').val('0').text('Name').appendTo($select);
$('<option/>').val('1').text('Position').appendTo($select);
$('<option/>').val('2').text('Office').appendTo($select);
$('<option/>').val('3').text('Age').appendTo($select);
$('<option/>').val('4').text('Start Date').appendTo($select);
$('<option/>').val('5').text('Salary').appendTo($select);
$('input[type="search"]').on('keyup change recheck', function() {
console.log('here');
var searchValue = $(this).val();
var columnSearch = $select.val();
table.columns().every(function() {
this.search('');
});
if (columnSearch == 'All') {
table.search(searchValue).draw();
} else {
table.columns(columnSearch).search(searchValue).draw();
}
});
$select.on('change', function() {
$('input[type="search"]').trigger('recheck');
});
