                    <div class="col-sm-4">
                        <?php
                            // set start and end year range
                            $dayArray = range(01, 31);
                            ?>

                                <?php
                                foreach($dayArray as $day) {
                    $selected = (day == 01) ? 'selected' : '';

                                ?>

我需要使用jquery获取数组的值，如何使用$("#dob").val()获取数组dob[]的值？

尝试使用json_encode，json_decode无效。 当我尝试提醒val时，它显示为undefined。

Answer 1

首先，您设置了id=dob[] HTML错误，它应该是name=[]

 $(document).ready(function() { $("#getValues").click(function() { var month = $("#month").val(); var year = $("#year").val(); var dob = month + " " + year; alert(dob); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <div class="col-sm-4"> <select name="dob['name']" class="form-control" id="month"> <option selected="selected" disabled>Month</option> <option value="1">Jan</option> <option value="2">Feb</option> <option value="3">Mar</option> </select> </div> <div class="col-sm-4"> <select name="dob['year']" class="form-control" id="year"> <option selected disabled>Year</option> <option value="2001">2001</option> <option value="2002">2002</option> <option value="2003">2003</option> </select> <button id="getValues">Get Values</button> </div> 

这是我给的基本代码！ 希望您有主意并继续进行编码
