responseResult.addObject ("entSetCharges", new EntSetCharges ());
роект основан на весенней загрузке, Thymeleaf, mysql, html и Jquery.
Мой сценарий получить итерацию списка и показать данные в 1-м столбце таблицы в HTML и опубликовать данные (html-charName и сумму ввода), получаемые из динамических полей ввода, и сохранить их в связанных столбцах, поэтому потребуется хит весенней загрузки @RestController.
Но я получил ОШИБКУ Thymeleaf как
org.springframework.expression.spel.SpelEvaluationException: EL1007E: Свойство или поле 'chargeName' не может быть найдено в null
Вот полный код ...
/**
* This is for set charges form
*/
$(document).ready(function() {
$("select").change(function()
{
var amttype = $(this).val();
if (amttype == 1)
{
$("#amt1").show();
$("#amt2").hide();
$("#amt3").hide();
}
else if (amttype == 2)
{
$("#amt1").hide();
$("#amt2").show();
$("#amt3").hide();
}
else if (amttype == 3)
{
$("#amt1").hide();
$("#amt2").hide();
$("#amt3").show();
}
else {
$("#amt1").hide();
$("#amt2").hide();
$("#amt3").hide();
}
});
