好的,所以我用同样的方式完成的所有其他功能到目前为止都有效。无论出于何种原因,这个都不会起作用。我不知道是否有一些我遗漏的东西,或者前面的代码中可能存在的错误可能导致这种情况。这是我的代码:
jQuery("#teamTab_addPlayerForm").on('change', 'select#teamTab_suggestedPlayer', function(e) {
e.preventDefault();
alert('It Worked');
});
这是调用它的PHP文件:
$output .= '<div id="ld_addPlayerFunction" style="clear:both; width:100%;"><h3>Add Player</h3>';
$standins = $wpdb->get_results('SELECT * FROM ' . $wpdb->prefix . 'kdc_user_sync ORDER BY computedMMR ASC');
$output .= '<form id="teamTab_addPlayerForm" action="" method="POST">
<select id="teamTab_suggestedPlayer" name="suggestedPlayer">
<option value="base">Suggested Player</option>';
foreach($standins as $standin){
$playerID = $wpdb->get_var('SELECT ID FROM ' . $wpdb->prefix . 'leagueDesigner_players WHERE userID = ' . $standin->userID);
$test = true;
if($playerID != ''){
$leagueTest = $wpdb->get_results('SELECT * FROM ' . $wpdb->prefix . 'leagueDesigner_league_players WHERE playerID = ' . $playerID);
foreach($leagueTest as $test){
if ($test->leagueID == $leagueID){
$test = false;
}
}
}
if($standin->computedMMR < ($suggestedMMR + 100) && $standin->computedMMR > ($suggestedMMR -100) && $test == true){
$output .= '<option value="' . $standin->userID . '">' . substr($standin->profileName, 0, 20) . ' - ' . $standin->computedMMR . ' MMR</option>';
}
}
$output .= '</select><br />';
$output .= '</form>';
然后在脚本中稍后回显输出。所以一个用户告诉我使用文档而不是#teamTab_addPlayerForm并且它可以工作,但我想知道为什么这个以前的代码工作正常而且那个没有:
jQuery("#teamTab_teamListForm").on('change', 'select#teamTab_teamSelect', function (e) {
e.preventDefault();
jQuery(this).attr('disabled', true);
var teamID = jQuery(this).val();
jQuery('select#teamTab_leagueSelect').attr('disabled', true);
var leagueID = jQuery('select#teamTab_leagueSelect').val();
data = { action: "leagueDesignerTeamsTabLoadTeamPlayers", leagueID: leagueID, teamID: teamID };
jQuery.ajax({
type: 'POST', url: ajaxurl, data: data, dataType: 'html', success: function(response) {
if (response == "error") {
jQuery('select#teamTab_teamSelect').attr('disabled', false);
alert('There was an error processing your request');
}
else {
jQuery('select#teamTab_teamSelect').attr('disabled', false);
jQuery('select#teamTab_leagueSelect').attr('disabled', false);
jQuery('.ld_teamEdit').remove();
jQuery('#ld_addPlayerFunction').remove();
jQuery('div#ld_teamTabTeamInfo').remove();
jQuery('#teamTab_teamListForm').after(response);
}
}});
});
这是以相同方式处理选择框的代码。这是PHP代码:
function leagueDesignerTeamsTabLoadLeagueTeams () {
global $wpdb;
$leagueID = $_POST['leagueID']; //Pull the POST'd leagueID
$output = '<select id="teamTab_teamSelect" name="team"><option value="">Choose a Team</option>'; //Output...
$errors = 0; //Error checking...
$teams = $wpdb->get_results('SELECT * FROM ' . $wpdb->prefix . 'leagueDesigner_teams WHERE leagueID = ' . $leagueID);
foreach($teams as $team){
$output .= '<option value="' . $team->teamID . '"';
if ($_POST['team'] == $team->teamID){
$output .= ' selected';
}
$output .= '>' . $team->teamID . '. ' . $team->teamName . '</option>';
}
if (!$teams) {
$errors++;
}
$output .= '</select>';
if ($errors == 0) { echo $output; } else { echo 'error'; }
die(); // this is required to return a proper result
}

元素是在页面加载后创建的,因此您需要将其绑定到已存在的元素(参见下文)
$(document).on('change', '.class-name', function () {
//Commands to run on change
});
