jq 解析josn字符串

 

 

1. var obj = jQuery.parseJSON("${ruleModel.rules}");

2.  var obj = eval("("+"${ruleModel.rules}"+")");

//上面两种方式解析josn 字符串，第一种要求规范的josn格式（要求键和值 都要有双引号），第二种能够满足非规范格式的josn字符串

 

if(obj[i].field=="EXPECTED_INCOME") //利率
{
var val;
val=obj[i].value.replace('[','');
val=val.replace(']','');    
var arr= val.split(',');

$("input[name='minRate']").val(arr[0]);
$("input[name='maxRate']").val(arr[1]);
}

 

if(obj[i].field=="OBTAIN_CHANNEL") //资产来源
{
var val;
val=obj[i].value.replace('[','');
val=val.replace(']','');    
var arr= val.split(',');
for(var j=0;j<arr.length;j++)
{    
$("input[name='OBTAIN_CHANNEL']").each(function(){
if($(this).val()==arr[j])
{
$(this).attr("checked", true); 
}
});
}

}

3.ajax 的 dataType: 'json',

function uploadFile(obj, type) {
var fd = new FormData();
fd.append("upload", 1);
fd.append("file", $("#fileUpload1").get(0).files[0]);
$.ajax({
url: "../UploadHandler.ashx",
type:"post",

processData: false,
contentType: false,
dataType: 'json',// 返回值类型 一般设置为json 
data: fd,

success: function (data) // 服务器成功响应处理函数 
{
console.log(data);
console.log(data.Msg);


},
error: function (data)// 服务器响应失败处理函数 
{
console.log("服务器异常");
}
});
return false;
}
