Delphi调用JavaScript解析Json
1.首先加入ComObj单元
2.加入函数
functin RunJs(const JsCode,JsVar:string):string;
var
script:OleVariant;
begin
try
Script :=CreateOleObject('ScriptControl');
Script.Language :='JavaScript';
Script.ExecuteStatement(JsCode);
Result :=Script.Eval(JsVar);
except
result :='';
end;
end;
在Button1的OnClick事件中写入
S :=RunJs(Memo1.Text,'str');
Showmessage(S);
在Memo1中写入str=1+2，弹出3
如果写入以下JSON解析函数，则弹出解析后的结果
function ShowJson() {
var UserList=[
{"UserID":11,"Name":{"FirstName":"Trudy","LastName":"L1"},
{"UserID":11,"Name":{"FirstName":"F1","LastName":"L2"}}
];
return UserList[0].Name.FirstName;
}
str=ShowJson();
则弹出Trudy
或者用FastScript也可以解析，功能更强
