我正在尝试从表单中获取按名称分组的无线电输入列表，它们都有不同的名称。我正在尝试使用它们创建一个数组，如果选中它们，则将1附加到数组，否则追加0。没有弹出警告框，因此我假设函数processDataForFinalization未被调用。
我不知道我是如何附加到数组有什么问题。或者，如果这是一个更大的错误。
提前致谢。
EDIT4 以下是updateBallot.php代码
TwoResults.txt看起来像：
0 0 0 0 0 0 0 0
3 4 1
<?php
$name = $_POST['name'];
$points = $_POST['points']; //array of user vote
echo $points;
$txt_file = file_get_contents($name.'Results.txt');
$rows = explode("\n", $txt_file); // rows-array separated by new line
foreach($rows as $row => $data)
{
$row_datas = explode(' ',$data);
}
$goods = $row_datas[0];
$goodies = $row_datas[1];
$newArr = [];
for($j=0;$j<count($points);$j++) {
$newArr[$j] = $goods[$j] + $points[$j];
}
$newText = "";
foreach($newArr as $nArr => $nData) {
$newText .= $nData." ";
}
$newText .= "\n";
$secondNewArr = [];
$sizeOfBottom = count($goodies);
for($k=0;$k<$sizeOfBottom;$k++) {
$secondNewArr[$k] = $goodies[$k];
}
foreach($secondNewArr as $neArr => $neData) {
$newText .= $neData." ";
}
$myFile = fopen($txt_file,"w+");
fwrite($myFile, $newText);
fclose($myFile);
?>

编辑 getActualData（）
这是getData()，这个函数有效，所以我不确定为什么getActualData()不起作用，因为它们基本上是一样的。
function getData() {
var parts = 0;
for(var i=0; i<numQs; i++){
var checked = false;
var inp = document.getElementsByName('input'+i);
for(var j=0; j<inp.length && checked == false; j++){
if(inp[j].checked) {
checked = true;
parts++;
}
}
}
if(parts != numQs){
window.alert('Please vote for at least one candidate per race.');
return false;
} else {
window.alert('Okay');
getActualData();
//return true;
}
}
function processDataForFinalization() {
$.ajax({
url: 'updateBallot.php',
type: 'post',
data: {"points" : val, "name":name},
success: function(data) {
// Do something with data that came back.
window.alert(data);
//return true;
}
});
}
var val = [];
function getActualData() {
for(var k=0;k<numQs;k++) {
var inpu = document.getElementsByName('input'+k);
for(var jk=0;jk<inpu.length;jk++) {
window.alert('almost there');
if(inpu[jk].checked) {
window.alert('hello');
val.array_push(1);
window.alert(val.length);
} else {
val.array_push(0);
}
}
}
processDataForFinalization();
}
