我正在尝试使用增加的javascript $questNumber
和jQuery questNum
$.get()
Console.log告诉我js questNum
var正在递增。
但即使我在JS方面增加了值,echo "testing..." . $questNumber;
输出1
。这意味着更新后的值不会发送到$questNumber
来更新数据库,并将相应的新值集返回给javascript端。
JavaScript:
/*Check player sentence input to see if grammar is correct*/
function submitMe() {
var input = document.getElementById('textBox').value;
log(questNum);
if ($.trim(input) == getSentence(questNum)) {
$("#responseVerify").html("Great job");
$("#textBox").val("").trigger("change");
//post successful quest to Quests.php, which will increment questcount there, and get new vocab words
questNum++;
log(questNum);
$.get("php/Quests.php", { "_questNum" : questNum},
function() {
$(".wordBank_Words").empty();
$.each(wordsArray, function(key, value) {
$(".wordBank_Words").append("<div class='bank-word' word='" + key + "' ><b>" + key + "</b>: " + value + "</div>");
});
});
}
else {
$("#responseVerify").html("Keep going...");
}
}
PHP:
<?php
//if user's input is correct, increment task number, get next vocabulary
include 'DbConnect.php';
$questNumber = (isset($_GET['_questNum']) ? ($_GET['_questNum']) : 1);
echo "testing..." . $questNumber;
$qry =
"SELECT t.*, v.*
FROM task t
INNER JOIN vocabtask vt ON (t.id = vt.taskid)
INNER JOIN vocab v ON (v.id = vt.vocabid)
WHERE vt.taskid = " . $questNumber;
$sql = $mysqli->query($qry);
$wordsArray = array();
while ($row = $sql->fetch_assoc()) {
echo $row['chinese'];
$wordsArray[$row['chinese']] = $row['english'];
}
echo "testing..." . $questNumber;
mysqli_close($mysqli);
echo "<script type='text/javascript'> var wordsArray = " . json_encode($wordsArray) . "; </script>";
?>
HTML:
<!--ROW 3: RESPONSE-->
<div class="row">
<div class="span12">
<!--Select a word shown and it gets added to the input box-->
Create sentence:
<input type="text" id="textBox" value="" />
<br/>
<button onclick="submitMe()" id="testButton" >Submit Response </button>
<br/>
<i><span id="responseVerify"></span></i><br />
<div class="wordBank_Headings">Word Bank:
<span class="wordBank_Words"></span>
</div>
<div class="wordBank_Headings">Hint:
<span class="wordBank_Hint"></span>
</div>
<div class="wordBank_Headings">New Words:
<span class="new"></span>
</div>
</div>
</div>
答案 0 :(得分:0)
试试这个ajax格式
$.ajax({
type: "GET", //method
url:"php/Quests.php", //your ajax page
data:"_questNum="+questNum, //pass values to this data
success: function(data){ //success function
alert('sasas');
}
