js变量名中的数字用另一个变量替换怎么实现

Answer 1

[javascript]

var test='{ colkey: "col", colsinfo: "NameList" }'

var test='{ colkey: "col", colsinfo: "NameList" }'

2.把文本转化为对象

[javascript]

var test='{ colkey: "col", colsinfo: "NameList" }'

var obj2=eval("("+test+")");

alert(obj2.colsinfo);

var test='{ colkey: "col", colsinfo: "NameList" }'

var obj2=eval("("+test+")");

alert(obj2.colsinfo);

3.把文本转化为数组

[javascript]

var test='["colkey", "col", "colsinfo","NameList" ]'

var obj2=eval("("+test+")");

alert(obj2.length);

Answer 2

var x="var a1";
var b="zz";
x.replace(/[0-9]{1}/,b);
eval(x);

Answer 3

var a="a123",b="b";

a.replace(/[0-9]{1}/,b)
