Notes for parsing strings in JSON format using eval ()
When using JavaScript built-in eval functions to convert strings in JSON format into JS objects, you need to use a pair " () " First wrap the string.
For example:
Set VaR Strtest = " {ID :\ " Cnlei \ " , URL :\ " HTTP: // Www.cnlei.com \ "}"; convert to JS object
Correct syntax:
VaR Objtest = Eval ( " ( " + Strtest + " ) " );
Incorrect syntax:
VaR Objtest = Eval (strtest );

Complete Test Code :
< Script Type = " Text/JavaScript " >
<! --
VaR Strtest = " {ID :\ " Cnlei \ " , URL :\ " HTTP: // Www.cnlei.com \"}";
VaR Objtest = Eval ( " ( " + Strtest + " ) " ); // Correct writing
// VaR objtest = eval (strtest); // error code
Alert (objtest. ID + " \ N " + Objtest. url );
// -->
< / SCRIPT>
