在我的模型中，我有一个隐藏的字段。我正在使用javascript（jQuery）修改其值。但是当我将表单提交给模型时，它仍然包含其初始值而不是通过javascript修改的值。我已检查是否javascript正在修改值，并确认正在修改值。但是当提交表单时，它正在发送初始值。 代码如下：
<?php
/*Model -- wrong_answers is my hidden field*/
namespace app\models;
use yii;
use yii\db;
use yii\base\Model;
use yii\web\UploadedFile;
class QuestionModel extends Model
{
public $quiz_id = null;
public $question = '';
public $choices = '';
public $explanation ="";
public $hints = array();
public $correct_answer = "";
public $wrong_answers = '{}';//when populating from already entered data use {"a":"as"} format instead of {'a':'as'}
public $wrong_answer = "";
public function rules()
{
return [
[['quiz_id'], 'safe'] ,
[['question'], 'required'] ,
[['correct_answer'], 'required'] ,
[['wrong_answers'], 'safe'] ,
[['wrong_answer'], 'safe'] ,
[['explanation'],'required']
];
}
public function get_quiz($quiz_id) {
$ret = array();
$command = Yii::$app->db->createCommand("CALL get_quiz(:qz_id)");
$command->bindParam(":qz_id", $this->quiz_id);
$result = $command->queryAll();
if(sizeof($result) > 0) {
$ret = $result[0] ;
}
return $ret;
}
public function save_question() {
$ret = false;
//echo "quiz- id is ".$this->quiz_id;
$quiz_details = $this->get_quiz($this->quiz_id);
if(sizeof($quiz_details)) {
$quiz_data = $quiz_details['quiz_data'];
$quiz_data = json_decode($quiz_data);
$choices = [];
echo $this->wrong_answers;
exit;
$wrong_answers_array = json_decode($this->wrong_answers);
if($this->wrong_answer)
array_push($wrong_answers_array, $this->wrong_answer);
print_r($wrong_answers_array);
exit;
foreach($wrong_answers_array as $wr_ans) {
array_push($choices,array('choice'=>$wr_ans));
}
$question_data = array('question'=>$this->question,'explanation'=>$this->explanation,'choices'=>$choices);
$ret = false;
}
return $ret;
}
public function getHint($key) {
return $this->hints[$key];
}
}
Controller - actionAdd_question是动作

Javascript - ＃wrong_answers是我隐藏的输入ID
var wrongAnswers = {};//{1:answer1,2:answer2...};
var randCount = 0;//radom count for setting as wrongAnswers attribute
//initialise wrong answers json from database
$(document).ready(function() {
console.log($('#wrong_answers').val());
wrongAnswers = jQuery.parseJSON($('#wrong_answers').val());
console.log(wrongAnswers);
$('#add-answer').click(function() {
var wrongAns = $('#wrong_answer').val().trim();
if(wrongAns) {
wrongAnswers[randCount] = wrongAns;
randCount++;
generateWrongAnswers();
$('#wrong_answer').val("");
// alert($('#wrong_answers').val());
}
});
generateWrongAnswers();
});
function generateWrongAnswers() {
$('#wrong-group').hide();
var html = '';
for(var wrongIdx in wrongAnswers) {
//console.log("w is ".wrongAnsIdx);
$('#dummy-wrong-answer').html(wrongAnswers[wrongIdx]);
$('#dummy-wrong-ans-delete').attr('name',wrongIdx);
html += $('#edit-list-dummy').html();
}
if(html) {
$('#wrong-group').show();
$('#wrong-answers').html(html);
}
var jsonData = JSON.stringify(wrongAnswers);
$('#wrong_answers').val(jsonData);
// $('#test').val(jsonData);
//$('#correct_answer').val("Mallu");
// alert($('#wrong_answers').val());
}
function deleteWrongAnswer(idx) {
delete wrongAnswers[idx];
generateWrongAnswers() ;
}
答案 0 :(得分：0)
Finall解决了它。问题是，我意外地包含了两个具有相同id的隐藏输入字段。删除了一个并解决了
