清除DataTables搜索输入后，该表没有响应
清除DataTables搜索输入后，该表没有响应
提问于 2021-09-29 07:42:01
这是在添加DataTables外部搜索框后出现的问题。当我单击搜索框右侧的clear按钮时，表没有响应，它仍然显示搜索结果，仍然停滞不前。
但是DataTables默认搜索框没有这个问题，这个问题应该如何解决？
DataTables初始化代码。
$(document).ready( function () {
var table = $('#example').DataTable({
"dom": 'ifrtp'
});
$('#mySearchText').on( 'keyup', function () {
table.search( this.value ).draw();
} );
} );示例测试链接：https://codepen.io/zhao3574/pen/KKqJWpR
如有任何帮助，请提前谢谢！

这里有一个解决方案：
1.)您不需要插入自己的搜索输入，因为当您操作dom: option时，DataTables会创建自己的搜索输入。DataTables筛选器的筛选器控制元素是f - filtering input。我对您的代码做了几处更改，然后使用x按钮清除表格并重新绘制它。
话虽如此，表初始化之后的jQuery事件也是不必要的。
表格HTML dom的操作可以在https://datatables.net/reference/option/dom中找到。
更新
下面是一个如何实现您想要实现的目标的示例。我在input filter旁边创建了一个按钮，并为其分配了ID #test。您需要在jQuery onclick事件中使用以下内容，以便它们在clear button事件发生时触发。
将搜索输入值设置为空字符串，并应用空字符串搜索以将表重新绘制为其原始形式。如果你不想要这个按钮，现在你知道了在某个事件中你必须采取什么行动来完成你需要做的事情。
$('#mySearchText').val('');
table.search('').draw();
$(document).ready( function () {
var table = $('#example').DataTable({
"dom": 'irtp'
});
$('#mySearchText').on( 'keyup', function () {
table.search( this.value ).draw();
});
$('#test').click(function() {
$('#mySearchText').val('');
table.search('').draw(); //required after
});
} );body {
