jQuery uses Ajax to submit messages and forms without refreshing

PbootCMS itself will return Json data when submitting using ajax request, so we can implement ajax submission without using API, and customize page prompts to improve user experience.

1. Message form

<form onsubmit="return submsg(this);">
    联系人<input type="text" name="contacts" required id="contacts">
    手　机<input type="text" name="mobile" required id="mobile">
    内　容<textarea name="content" id="content"></textarea>
    验证码<input type="text" name="checkcode" required id="checkcode">
    <img title="点击刷新" src="{pboot:checkcode}" onclick="this.src='{pboot:checkcode}?'+Math.round(Math.random()*10);" />
    <button type="submit">提交留言</button>
</form>

2. Ajax submission

<script>

//ajax提交留言，由于涉及到提交地址标签的解析，JS需要放在html文件中
function submsg(obj){
  var url='{pboot:msgaction}'; //如果是自定义表单则使用地址{pboot:form fcode=*}
  var contacts=$(obj).find("#contacts").val();
  var mobile=$(obj).find("#mobile").val();
  var content=$(obj).find("#content").val();
  var checkcode=$(obj).find("#checkcode").val();
  
  $.ajax({
    type: 'POST',
    url: url,
    dataType: 'json',
    data: {
        contacts: contacts,
        mobile: mobile,
        content: content,
        checkcode: checkcode
    },
    success: function (response, status) {
      if(response.code){
         alert("谢谢您的反馈，我们会尽快联系您！");
         $(obj)[0].reset(); 
      }else{
         alert(response.data);
      }
    },
    error:function(xhr,status,error){
      alert('返回数据异常！');
    }
  });
  return false;
}
</script>
