第一个案例：jquery 遍历json对象集合 常用示例
jsp中
jsonText的格式：
{"status":"200","msg":[{"id":"1","name":"n1"},{"id":"2","name":"n2"}]}
{"status":"500","msg":"异常信息"}
java中：
List pngFileList = new ArrayList();//某对象集合
if(null != pngFileList && pngFileList.size() > 0) {
JSONArray pngFileArray =JSONArray.fromObject(pngFileList);
}
if(null != pngFileArray){
this.setTextAjax(pngFileArray.toString());
//异常的格式
//this.setTextAjax("{\"status\":\"500\",\"msg\":\""+errormsg+"\"}");//没有记录
/**
* ajax返回html,包括json形式
*
* @param responseContent
*/
public void setTextAjax(String responseContent) {
try {
HttpServletResponse response = getHttpResponse();
response.setContentType("text/html");
response.setCharacterEncoding("UTF-8");
response.setHeader("Pragma", "No-cache");
response.setHeader("Content-Type", "text/html");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
PrintWriter out = response.getWriter();
out.print(responseContent);
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
// ajaxResponse = new StringBufferInputStream(responseContent);
}
第二个案例：jQuery 遍历JSON 对象
不说别的，直接贴代码：
第三个案例：jquery中遍历读取json串中的对象
假设我们从服务器端获取如下的json串，其中包括数组。我们该如何遍历读取呢？
代码如下:{"result":null,"rows":[{"caishen":"东","fushen":"西北","huajiazi":"甲子","id":1,"nayin":"大海水","shengmen":"南","simen":"北","wugui":"西","xishen":"东南","yanggui":"西南","yingui":"东北"},{"caishen":"东北","fushen":"北","huajiazi":"乙丑","id":2,"nayin":"大林木","shengmen":"西北","simen":"西南","wugui":"东南","xishen":"东","yanggui":"西","yingui":"南"},{"caishen":"西","fushen":"东","huajiazi":"丙寅","id":3,"nayin":"石榴木","shengmen":"北","simen":"西北","wugui":"南","xishen":"东南","yanggui":"东北","yingui":"西南"}],"total":3}
使用.each难度太高，直接js读取吧
通过如上的方式就能获取json串的json对象并进行输出。
为大家分享这么多的案例，就是想帮助大家掌握jquery遍历json对象集合的方法，真正理解，希望这篇文章可以帮助到大家。
