jQuery在POST后不更改textarea的值 [英] Jquery not changing value of textarea after POST

问题描述

我有一个页面，将textareas的值输入到MySQL数据库中.由于这是伪提交，因此在输入数据后，我手动将textarea的值更改为no.但是，按提交后，数据输入正确，但文本区域无法清除.根据答案的数量，HTML(下面)会被多次响应.

I have a page that inputs values of textareas into a MySQL database. Since this is a pseudo-submit I manually change the value of the textarea to nothing after the data is inputted. However, after I press submit, the data is inputted properly, but the textarea does not clear. The HTML (below) is echoed several times depending on the number of answers.

JavaScript:

JavaScript:

$('document').ready(function () {
    $('.commentContainer').load('../writecomment.php');

    $("form").on("submit", function (e) {
        e.preventDefault();

        var $form = $(this);
        $.ajax({
            "url": $form.attr("action"),
            "data": $form.serialize(),
            "type": $form.attr("method"),
            "response": function () {
                $('.commentContainer').load('../writecomment.php');
                $('.commentBox').val(""); //this line doenst work
            }
        });
    });
});

HTML:

<textarea class='commentBox'  wrap='soft' name='comment'></textarea>
<input type='submit' value='comment' class='submitCommentBox'>

推荐答案

$.ajax 在其options对象中不使用response参数.您应该使用

success: function () {

代替

"response": function () {
