如果文本字段为空,我需要创建jQuery验证表单然后出现警告。

这是我的代码:

<form action="" method="POST">
    <input type="checkbox" name="dropshiper_ceck" id="id_dropshiper_ceck">
    <label><b><?php echo $text_dropship; ?></b></label>
    <div class="" id="id_dropshiper_form" name="dropshiper_form">
        <hr/>
        <p>
            <?php echo $text_dropship_name; ?>
        </p>
        <input type="text" name="nama_dropshiper" style="width: 97%" placeholder="<?php echo $text_add_name_dropshiper; ?>" id="id_nama_dropshiper" value="">
        <br/>
        <br/>
        <p>
            <?php echo $text_dropship_telp; ?>
        </p>
        <input type="text" name="nomor_telp" style="width: 97%" placeholder="<?php echo $text_add_number_phone_dropshiper; ?>" id="id_nomor_telepon_dropshiper" value="">
    </div>
</form>

$('#id_dropshiper_ceck').change(function(){

    // Check the textbox when the checkbox is checked
    if ($('#id_dropshiper_ceck').prop('checked') == true){
        if ($('#id_nama_dropshiper').val() == ""){
            // alert message
      alert('Warning Message');
        }
        if ($('#id_nomor_telepon_dropshiper').val() == ""){
            // alert message
      alert('Warning Message');
        }
  }
})

我想你想在单击复选框时检查文本框。
