Write code when encountered this problem, how to add dynamic key and value in the object, from the online Baidu has, in this record, the great god please ignore.

As for how dynamic, circulation or how to do not say.

Say the principle, first look at the code:

1 //define values for key and value2 varKey = "Name";3 varValue = "lqj12138";4 5 //declaring an object6 varparam = {};7 8 //declaring an execution statement as a string9 varstr = "param." + key + "=" +value;Ten  One //use eval to perform Aeval (str);

Should all be able to read, very simple.

The values of key and value can be defined arbitrarily, dynamically assigned to them, and then execute the following statement to add dynamically.

Rookie one, the great God do not ridicule.
