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$.toJSON把数据对象转换为json格式。
使用JavaScript构建JSON格式字符串
JavaScript代码:
在这里包含了javascript代码。$(“#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:
">
HTML代码:
JSON输出
{
"userDetails":{
"user":{
"name":"Srinivas Tamada",
"email":"srinivas@9lessons.info",
"password":"Srinivas Tamada",
"gender":"male",
"websites":["www.software8.co","www.heatpress123.net","www.0769zzw.com"]
}
}
}
JSON Encoded
对特殊字符进行编码,会把以下字符进行编码:
, / ? : @ & = + $ #
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
GetPostAjax.js
这里定义了jquery的ajax请求方法。
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");
}
});
}
