Question

怎么用一个变量去替换一个属性名的数字

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);
