Ajax调用两次会导致消息重复 - Ajax call twice cause duplicate message

我正试图找出ajax调用两次如此重复的消息的问题。我第一次点击sendPLR按钮，消息不会出现。然后，当再次单击按钮时，它会显示两次消息。我检查了Chrome上的网络选项卡，它也没有显示第一个ajax调用。再次按下按钮时会显示重复呼叫。这是我的HTML代码。这是我第一次处理这样的大形式。请帮忙！！！！我使用wordpress

<p><input type='button' id='sendPLR' value='Submit' onclick='postPLRData();'></p>
<div id="plr_message"></div>

id="plr_message"是消息显示的位置。下面是我的jquery代码

function postPLRData() {
    $j('#sendPLR').click(function(e) {
        e.preventDefault();
        $j.ajax({
            url: ajaxurl,
            type: 'POST',
            dataType: 'HTML',
            data: { action: 'submitPLR', PLRData: frmData },
            success: function(backData) {
                if (backData !== '') {
                    $j('#plr_message').append('Form has been submitted successfully');
                }
                else { 
                    $j('#plr_message').append('Ops!!!, form could not be submitted'); 
                }
            }
        });
    }); 
}

这是我的php代码

function insertPLR()
{
    $return      = array();
    $jsondecode  = $_POST['PLRData'];
    $queryUser = ($jsondecode['user'] === '') ? $jsoncode['user'] : wp_get_current_user()->user_login;
    echo json_encode($queryUser);
    die();
}
add_action('wp_ajax_submitPLR', 'insertPLR');

感谢

remove `onclick='postPLRData();'` from submit button and try this code

$(document).ready(function() {
$j('#sendPLR').on('click',function(e) {
        e.preventDefault();
        $j.ajax({
            url: ajaxurl,
            type: 'POST',
            dataType: 'HTML',
            data: { action: 'submitPLR', PLRData: frmData },
            success: function(backData) {
                if (backData !== '') {
                    $j('#plr_message').append('Form has been submitted successfully');
                }
                else { 
                    $j('#plr_message').append('Ops!!!, form could not be submitted'); 
                }
            }
        });
    }); 
 })
