How to communicate data between C and View

This time I will show you how to communicate data between C and View. What are the precautions for data communication between C and View? The following is a practical case, let's take a look.

jQuery.post(url, [data], [callback], [type])

url,[data],[callback],[type]String,Map,Function,StringV1 .0url: Send request address.

data: Key/value parameters to be sent.

callback: When the transmission is successful, the callback function .

type: Return content format, xml, html, script, json, text, _default.

Format:

$.post("test.php", function(data){
  alert("Data Loaded: " + data);
 });
$.get("comment/getComments?parentId="+parentId+"&topicId="+topicId,function(data){
 var appendButton ="";
 var append = "";
 if(data!=""){
  var arr = data.split("$");
  var allTr="";
  for(var i = 0;i<arr.length><tr><td>"+content+"</td></tr>
<tr><td>"+time+"</td></tr>";
  appendButton = appendButton+table+"<button>回复</button>";
  }
  appendButton = appendButton+"<button>我也说一句</button>";
 }
 appendButton = appendButton+"<p></p>
<p></p>";
 if(data==""){
  appendButton = appendButton+"<textarea>@"+userName+"...."+"...."+parentId+":</textarea><button>发表</button>";
 }
 $("#addCommentId"+parentId).html(appendButton);
 });</arr.length>

Backend:

@RequestMapping(value = "/saveAndGetComments", params = {"topicId","parentId"}, method = RequestMethod.POST)
 @ResponseBody
 public String saveAndGetComments(long topicId,Comment comment,long parentId) throws UnsupportedEncodingException{
 comment.setParentId(parentId);
 commentService.save(comment,topicId);
 List<comment> comments=commentService.listByCommentId(parentId);
 return append(comments);
 }
 
 private String append(List<comment> comments) {
 StringBuffer sb=new StringBuffer();
 for(int i=0;i<comments.size><p style="text-align: left;"><span style="color: #ff0000">Note <strong></strong>, use springmvc3 annotation @responseBody to pass parameters. </span></p>
<p style="text-align: left;">Frequently used js functions: <strong></strong></p>The above data is transmitted using json, and when js parses the date passed by json, it is not in the format we want. , then you need to operate on the date: <p style="text-align: left;"></p>First pass the past date, set it to time and pass it to date.getTime()<p style="text-align: left;"></p>
<p style="text-align: left;">Then operate in js: <strong></strong></p>
<pre class="brush:php;toolbar:false">var date= "/Date("+time+")/";
date = DateFormat(date);
/**
 * 处理时间
 * @param value
 * @returns {String}
 */
function DateFormat(value) {
  var date = new Date(parseInt(value.replace("/Date(", "").replace(")/", ""), 10));
  var month = date.getMonth() + 1  I believe you have mastered the method after reading the case in this article.
