我需要使用jquery获取数组的值，如何使用dob[];

获取数组$("#dob").val()的值

尝试使用json_encode，json_decode无效。当我试图提示val显示为未定义时。

Answer 1

首先，您设置id=dob[]的错误HTML应该是name=[]

＆＃13;

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

＆＃13;

<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>
