如果你现在正在使用Restful API,并且你需要通过web项目来构建JSON格式字符串的响应,那么这篇文章将帮助你使用javascript来创建json格式字符串。这是非常有用的,我们将通过jQuery插件$.toJSON把数据对象转换为json格式。

在这里包含了javascript代码。$(“#form”).submit(function(){}- delete_button是form标签的ID,我们通过element.val()调用表单输入框的值。 代码如下:
代码如下:
代码如下:
{
"userDetails":{
"user":{
"name":"Srinivas Tamada",
"email":"srinivas@9lessons.info",
"password":"Srinivas Tamada",
"gender":"male",
"websites":["www.software8.co","www.heatpress123.net","www.0769zzw.com"]
}
}
}
对特殊字符进行编码,会把以下字符进行编码
:
代码如下:
, / ? : @ & = + $ #
jsondata=%7B%22userDetails%22%3A%7B%22user%22%3A%7B%22name%22%3A%22Srinivas%20Tamada%22%2C%22email%22%3A%22srinivas%409lessons.info%22%2C%22password%22%3A%22Srinivas%20Tamada%22%2C%22gender%22%3A%22male%22%2C%22websites%22%3A%5B%22www.9lessons.info%22%2C%22www.egglabs.in%22%2C%22www.fglogin.com%22%5D%7D%7D%7D
这里定义了jquery的ajax请求方法。
代码如下:
function post_data(url,encodedata, success){
$.ajax({
type:"POST",
url:url,
data :encodedata,
dataType:"json",
restful:true,
contentType: 'application/json',
cache:false,
timeout:20000,
async:true,
beforeSend :function(data) { },
success:function(data){
success.call(this, data);
},
error:function(data){
alert("Error In Connecting");
}
});
}
// 声明两个json数组
[java] view plain copy print?
JSONArray gResTable = new JSONArray();
JSONArray gCmtTable = new JSONArray();
// 声明json对象
ONObject outData = new JSONObject();
//把json数组加到json对象中
[java] view plain copy print?
outData.put("ResTable", gResTable);
outData.put("CmtTable", gCmtTable);
//此时创建出来的如下:jsonData={"ResTable":[],"CmtTable":[]};
把json数据加到json数组中
for (int i = 0; i < 2; i ++)
{
JSONObject node = new JSONObject();
node.put("thumb_path", "./Image/" + i +".gif");
node.put("flash_path", "./Image/" + i +".gif");
node.put("desc1", "可疑车辆" + i);
node.put("desc2", "");
node.put("desc3", "");
node.put("desc4", "");
node.put("title", "hello");
node.put("upload_time", (new java.util.Date()).toString());
node.put("uploader", "王二");
gResTable.put(node);
}
for (int i = 0; i < 2; i ++)
{
JSONObject node = new JSONObject();
node.put("logo_path", "./Image/" + i +".gif");
node.put("comment", "hello");
node.put("comment_time", (new java.util.Date()).toString());
node.put("author", "王二");
gCmtTable.put(node);
}
建出来的json格式如下:
[java] view plain copy print?
/*
jsonData={"ResTable":[
{"upload_time":"Sat May 26 20:16:37 CST 2012","title":"hello","flash_path":"./Image/0.gif","uploader":"王二","thumb_path":"./Image/0.gif","desc3":"","desc4":"","desc1":"可疑车辆0","desc2":""},
{"upload_time":"Sat May 26 20:16:37 CST 2012","title":"hello","flash_path":"./Image/1.gif","uploader":"王二","thumb_path":"./Image/1.gif","desc3":"","desc4":"","desc1":"可疑车辆1","desc2":""}],
"CmtTable":
[{"author":"王二","logo_path":"./Image/0.gif","comment":"hello","comment_time":"Sat May 26 20:16:37 CST 2012"},
{"author":"王二","logo_path":"./Image/1.gif","comment":"hello","comment_time":"Sat May 26 20:16:37 CST 2012"}
]};
