Copy code The code is as follows:

var imgData = [

{ name: "p1", src: "images/p1.jpg" },

{ name: "p2", src: "images/p2.jpg" },

{ name: "p3", src: "images/p3.jpg" },

{ name: "p4", src: "images/p4.jpg" },

function getData(name) {

var picArr = imgData;

var picSrc;

if (cur_person.name == name) {

picSrc = cur_person.src;

}

}

return picSrc;

}

var g = getData("p1");
