我尝试从 Bootstrap 模式中获取下拉文本值,当我调用 val() 时它做得很好,但是当我调用 text() 来检索下拉文本时,它返回下拉文本堆栈

这是我的代码

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>

<body>
<!-- Large modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".category-modal">Select Category</button>

<!-- hidden fields to store modal result in -->

<div class="form-group">
<label for="main-pages" class="col-lg-4 control-label">this should contain index from page dropdown : </label>
<input type="text" id="main-pages">
</div>

<div class="form-group">
<label for="main-sub-pages" class="col-lg-4 control-label">this should contain text from sub-page dropdown : </label>
<input type="text" id="main-sub-pages">
</div>

<script type="text/javascript">
//called when user clicks login
function login() {
$("#main-pages").val($("#pages").val());
$("#main-sub-pages").val($("#sub-pages").text());
$(".category-modal").modal("hide");

$('.category-modal').on('hidden', function() {
console.log('page : '+$("#main-pages").val());
console.log('sub-page : '+$("#main-sub-pages").text());

注意:您需要将光标移动到第二个文本输入上才能看到下拉文本

最佳答案

改变

 console.log('page : '+$("#main-pages").val());
console.log('sub-page : '+$("#main-sub-pages").text());

为此

 console.log('page : '+$("#main-pages :selected").val());
console.log('sub-page : '+$("#main-sub-pages :selected").text());
