本文实例讲述了jQuery自动添加表单项的方法。分享给大家供大家参考。具体如下:
这里实现通过点击按钮动态添加一个表单输入项
<script type="text/javascript" charset="utf-8"> $(function() { var fieldCount = 1; $("#addFieldButton").click(function() { fieldCount++; if(fieldCount <= 5) { var fieldID = "recipient_email_" + fieldCount; $("#additionalEmails").append("<label for='"+fieldID+"'>Recipient Email "+fieldCount+": </label>"+ "<input type='text' name='"+fieldID+"' " + "id='"+fieldID+"' size='30'><br />" ); } else { alert("Maximum email fields reached."); } }); }); </script>
希望本文所述对大家的jquery程序设计有所帮助。
