Question

我需要将一些输入文本框的内容拉入数据库。显示第一个框，但我正在使用此Javascript动态创建其中一些：

var counter = 1;
var limit = 10;
function addInput(divName){
     if (counter !== limit)  {
          var newdiv = document.createElement('div');
          newdiv.innerHTML = " <input type='text' name='myInputs[]' size=40>";
          document.getElementById(divName).appendChild(newdiv);
          counter++;
     }
}

如何为表单添加一个值，对于每个创建的框都是不同的，以便我可以在PHP中引用它们？

谢谢！

编辑：从头开始，我从来没有尝试过使用数组来对输入进行分组，但它的工作方式却是如此。将输入的名称保留为myInputs []，但在php中引用如下：

$_POST[myInputs][0]

为您的第一个字段和

$_POST[myInputs][1]

为第二个等..

            <script>
                $(document).ready(function(){//fire when the page is ready
                    $('.addFields').click(function(){//any time someone clicks on a element with the class addFields
                        if( $('.myInputs').length < 10 ){ // if there are less than 10 input fields...
                            $($(this).attr('rel')).append("<br/><input type='text' name='myInputs[]' class='myInputs' size='40' id='myInputs"+($('.myInputs').length)+"'>");
                            // add another input field with an ID equal to it's place in line.
                                }
                    });
                });
            </script>

        </head>
        <body >
            <a rel="#addToMe" class="addFields" href="#">Add a field</a><!-- the triggering element this can be anything that can be clicked on-->
            <div id="addToMe"><!-- the element holding our input fields, new ones get added to the back of here, note that the trigger's rel attribute is the ID of this attribute and started with a "#' ID identifier-->
                <input type='text' name='myInputs[]' class='myInputs' size='40' id='myInputs0'>
            </div>

        </body>
