这是我的HTML：

<input type="text" class="keyword" name="keyword" id="keyword" placeholder="Search video...">
<button id="search-keyword">Search</button>

当我单击“搜索”按钮时，启动如下脚本：

if($(\'.current\').hasClass(\'search-select\')){
    action = \'my_create_posts_search\'; //php function to do 
    ab = document.getElementsByClassName(\'keyword\')[0].value; //get the value of input
}

然后，Ajax函数启动：

 $.ajax({
    type: "POST",
    url: ajax_params.ajax_url, //wordpress ajax
    data: {
     \'action\': action, //php function to do  
     \'ab\': ab, //value of input
},

然后操作开始，执行的代码如下：

function my_create_posts_search($name) {
 //Pagination for posts
 $response = \'\';
 $paged = (int) (!is_null($_POST[\'clicked_times\'])) ? $_POST[\'clicked_times\'] : 0;

 $postsPerPage = 18;
 $postOffset = $paged * $postsPerPage;

 $args = array(
    \'posts_per_page\'  => $postsPerPage, //pagination
    \'offset\'          => $postOffset, //pagination
    \'category\'        => 42, //post category
    \'s\'               => $name, //value of input
    \'orderby\'         => \'date\',
    \'order\'           => \'DESC\',
 );
 ... other things...
}

当我想通过Post标签搜索时，一切都很完美。

如何实现此功能？

我希望我的代码能帮助你。谢谢
