我无法将不同的变量传递给我的 javascript 函数。开始:
我有基本构建数据行的 PHP 代码。我想要做的是通过 AJAX 调用分别保存每一行。这是我到目前为止所拥有的。发生的事情是第一行工作正常,但所有后续行都没有(javascript变量是第一行的变量)。
前端 PHP 代码
<?php
$result = mysql_query("SELECT * FROM scoresheet WHERE matchup_id = '$matchupid' AND team_id = '$teama' AND status = '1' ");
$num_rows = mysql_num_rows($result);
if ( mysql_num_rows($result) == 0 ) { echo "<div style='float:left;clear:both;'>Nothing found</div>"; } else {
while($row = mysql_fetch_array($result))
{
echo " <form name='input'>";
echo " <div class='tablecell'>".$row['full_name']."</div>";
echo " <div class='tablecell'>".$row['scoresheet_id']."</div>";
echo " <input type='hidden' id='scoresheet_id' name='scoresheet_id' value='".$row['scoresheet_id']."'></input>";
echo " <div class='labelAnswer'><input class='standardscore' type='textfield' id='presenta' name='presenta' value='".$row['present']."'></input></div>";
echo " <div class='labelAnswer'><input class='standardscore' type='textfield' id='sparea' name='sparea' value='".$row['spare']."'></input></div>";
echo " <div class='labelAnswer'><input class='standardscore' type='textfield' id='goaliea' name='goaliea' value='".$row['goalie']."'></input></div>";
echo " <div class='labelAnswer'><input class='standardscore' type='textfield' id='goalsa' name='goalsa' value='".$row['goals']."'></input></div>";
echo " <div class='labelAnswer'><input class='standardscore' type='textfield' id='assistsa' name='assistsa' value='".$row['assists']."'></input></div>";
echo " <div class='labelAnswer'><input class='standardscore' type='textfield' id='yellowa' name='yellowa' value='".$row['yellow']."'></input></div>";
echo " <div class='labelAnswer'><input class='standardscore' type='textfield' id='reda' name='reda' value='".$row['red']."'></input></div>";
echo " <input type='button' class='btnInput' style='float:left;margin-top:-2px;' onClick='updatescore()' value='Save'></input>";
}
}
?>
JAVASCRIPT代码
function updatescore() {
var presenta = document.getElementById('presenta').value;
var sparea = document.getElementById('sparea').value;
var goaliea = document.getElementById('goaliea').value;
var scoresheet_id = document.getElementById('scoresheet_id').value;
if (window.XMLHttpRequest) {
xmlhttp = new XMLHttpRequest();
}
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById("txtuser").innerHTML = xmlhttp.responseText;
}
}
xmlhttp.open("GET", "testajax-x.php?presenta="+presenta+"&sparea="+sparea+"&goaliea="+goaliea+"&scoresheet_id="+scoresheet_id, true);
xmlhttp.send();
}
