将字符串解析为Json-JSON.Parse

Question

String stored in the DB (Json format):

{"requiredParam":"value"}

(Razor)Getting a string from the model:

<a id="link-test" asp-controller="TestController" asp-action="TestAction">@model.param</a>

Parsing into JSON:

<script>
var obj = JSON.Parse(document.getElementById("link-test").innerHTML);
var requiredParam = obj.requiredParam;
</script>

using JSfiddle it shows:

JSON.Parse("{"required.Param":"value"}")

==> not working (the string that i am trying to parse have this format with the double quotes)

==> obj.requiredParam returns undefined

JSON.Parse('{"required.Param":"value"}')

==> Works

Main purpose is to use the obj.requiredParam Any suggestions?

Answer 1

Try this:

JSON.Parse('{"'+required.Param+'":"'+value+'"}')

Edit: I did not understand the question properly.. Apologies.

How ever you can escape the " using regex.

var str = document.getElementById("link-test").innerHTML;
str = str.replace(/"/g, '\\"');
var obj = JSON.Parse(str);
var requiredParam = obj.requiredParam;

Answer 2

解决方案是使用JObject.Parse和GetValue如下：

<a id="demo" asp-controller="Demo" asp-action="Demo">@Newtonsoft.Json.Linq.JObject.Parse(model.RequiredParam).GetValue("requiredParam")</a>

Answer 3

I assume your html looks like this

<div id="link-test">{"requiredParam":"value"}</div>

So first replace the quotes with String.replace and then you can get the json object from it by simply parsing it

var elem = document.getElementById("link-test").innerHTML;
var obj = JSON.parse(elem.replace(/"/g, '\"'));
console.log(obj.requiredParam);
