For example,
var test='{ colkey: "col", colsinfo: "NameList" }'
Obviously it is an object, but how to convert text into an object. When using eval(); be sure to add parentheses, otherwise the conversion will fail
Convert the text into an object
var test='{ colkey: "col", colsinfo: "NameList" }'
var obj2=eval("(" test ")");
alert (obj2.colsinfo);
Convert text into array
var test='["colkey", "col", "colsinfo","NameList" ]'
var obj2=eval("(" test ")");
alert(obj2.length);
