A simple example of JavaScript parsing json formatted data

The following string of json data is used to store the preloaded image path:

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" },

    { name: "p5", src: "images/p5.jpg" }

   ]

The following function can get the path SRC of each row through the name of json. Let's take a look at the code:

function getData(name) {

    var picArr = imgData;

    var picSrc;

    for (var i = 0; i < picArr.length; i++) {

  var cur_person = picArr[i];

  if (cur_person.name == name) {

   picSrc = cur_person.src;

  }

 }

 return picSrc;

}

The function returns the SRC of the row after execution.

var g = getData("p1");

console.log(g);

The result is: images/p1.jpg
