您好，我想将游戏(JS)的分数发送到 php，以便稍后将其存储在我的数据库中。但是当我单击提交按钮保存所有分数时，我没有得到任何值。我正在使用隐藏表单。
正如你所看到的，我有一个包含 xWon、xLose 等的表格...当我玩游戏时，一切正常，并且 JS 的分数会发布在该表格中。但是当我点击提交按钮时，当我在代码顶部使用 echo 时，我没有得到任何值..？ 这是 HTML 代码
<?php
if(isset($_POST['xWon_score']) && isset($_POST['xLose_score']) &&
isset($_POST['drawGame_score']) && isset($_POST['totalGames_score']))
{
$xWon_score = $_POST['xWon_score'];
$xLose_score = $_POST['xLose_score'];
$drawGame_score = $_POST['drawGame_score'];
$totalGames_score = $_POST['totalGames_score'];
echo $xWon_score . $xLose_score . $drawGame_score . $totalGames_score;
}else
echo "Testing......";
?>

<!-- Problem section ????? -->
<form method="post" action="game.php">
<input type="hidden" value="" id="Won_score" name="xWon_score"/>
<input type="hidden" value="" id="Lose_score" name="xLose_score"/>
<input type="hidden" value="" id="draw_score" name="drawGame_score"/>
<input type="hidden" value="" id="total_score" name="totalGames_score"/>
<!-- Save highscore button -->
<button type="submit" onclick="alert('Saving highscore')">Save highscore</button>
</form>
下面是打印 JS 分数的函数:
function recordWin(winner){
if (winner == "X"){
xWon++;
totalGames++;
}else if (winner == "O"){
xLose++;
totalGames++;
}else if (winner ==""){
drawGame++;
totalGames++;
}saveStats();
}
function saveStats(recordWin){
document.getElementById("xWon_score").innerText = xWon;
document.getElementById("xLose_score").innerText = xLose;
document.getElementById("drawGame_score").innerText = drawGame;
document.getElementById("totalGames_score").innerText = totalGames;
// Somthing Wrong here?
document.getElementById("Won_score").value = xWon;
document.getElementById("Lose_score").value = xLose;
document.getElementById("draw_score").value = drawGame;
document.getElementById("total_score").value = totalGames;
}
最佳答案
正确的语法是这样的:
document.getElementById("myInput").value;

document.getElementById("Won_score").value = xWon;
document.getElementById("Lose_score").value = xLose;
document.getElementById("draw_score").value = drawGame;
document.getElementById("total_score").value = totalGames;
