wordpress 中使用自带 admin-ajax.php

1前端页面

<script type="text/javascript">
        jQuery.ajax({
            type: ‘POST‘,
            url: "<?php echo admin_url( ‘admin-ajax.php‘ );?>",
            data: {
                action: ‘myajax_submit‘
            },
            success: function(res) {
                console.log(JSON.stringify("--"+res));
            }
        });
    </script>

2 后端functions.php里面接受请求

add_action( ‘wp_ajax_nopriv_myajax_submit‘, ‘myajax_submit‘ );
add_action( ‘wp_ajax_myajax_submit‘, ‘myajax_submit‘ );

function myajax_submit() {
	$response = json_encode( array( ‘success‘ => true ) );

	header( "Content-Type: application/json" );
	echo $response;
	// 这个很关键啊有木有: 别忘记 "exit"
	exit;
}

注意 前端action名字要和后端wp_ajax_nopriv_XXX名字后缀对应起来

剩下的按照格式相应改就可以了，

wp_ajax_nopriv_
