本文实例采用案例分析的方法介绍了jquery遍历json对象的三种情况，供大家参考，具体内容如下
第一个案例：
jsp中
rush:js;">
$.ajax({
url: "${applicationScope.rootpath}common/getContractPage.html?userConId=${userConId}",type: "post",dataType:"json",data: {},success: function (jsonText) {
if(jsonText){
var status = jsonText.status;
var msg = jsonText.msg;
if(status == '500'){
//有异常的信息时
alert(msg);
}else{
$.each(jsonText,function(i,item){
var pngPath = item[0];
var pngName = item[1];
});
}
}
}
});
jsonText的格式：
rush:java;">
{"status":"200","msg":[{"id":"1","name":"n1"},{"id":"2","name":"n2"}]}
{"status":"500","msg":"异常信息"}
java中：
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
}else{
$.each(jsonText,function(i,item){
var pngPath = item[0];
var pngName = item[1];
});
}
}
}
});}
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);
}
代码：

第三个案例：
jquery中遍历读取json串中的对象获取如下的json串，其中包括数组。我们该如何遍历读取呢？
代码如下:
