If i understood correctly, you can do the following:
如果我理解正确，您可以执行以下操作：
var json= {"Title":"Movie1","Year":"2013"};
var result="";
for( key in json){
result+= json[key];
}
You don't have to know the number of properties or it's names before hand. This should work for simple scenarios.
您不必事先知道属性的数量或其名称。这应该适用于简单的场景。

You first need to extract the JSON data using JSON.parse():
您首先需要使用JSON.parse()以下方法提取 JSON 数据：
var data = JSON.parse(json);
This assumes your JSON data is held in a variable named jsonwhich we've passed into the parse()method. This gives us the following JavaScript object:
这假设您的 JSON 数据保存在json我们传递给parse()方法的名为的变量中。这为我们提供了以下 JavaScript 对象：
{
Title: "Movie1",
Year: "2013"
}
We can now join the two values simply by concatenating them with the +symbol:
我们现在可以简单地通过将它们与+符号连接来连接两个值：
var result = data.Title + data.Year; // "Movie12013"

try something like this
尝试这样的事情
var jsonText = '{"Title":"Movie1","Year":"2013"}'
obj = JSON.parse(jsonText);
var string = obj.Title + obj.Year;

Assuming the JSON data is kept in a jsonVarNamevariable:
假设 JSON 数据保存在一个jsonVarName变量中：
jsonVarName.title + jsonVarName.year
