Question

Hi I am working in JavaScript. My code is:

<div id="myDiv" onClick="myfn()">
<img src="a.png">
<img src="b.png">
</div>

I want to get the source of the images and store it in the array on click of a button.
Any help ???

myfn() {    
  var a = new Array(); 
  var mainDivData = document.getElementById('myDiv').innerHTML;
  var mainDivData2 = mainDivData.getElementByTag('src');

  for(var i =0 ; i<mainDivData2.length; i ++) {
    //a[i] = mainDivData2;
    alert(a[i]);
  }
}

But nothing shown in the alert even alert window doesn’t opened.
Any help ???

Pure JavaScript solution:

var imgs = document.getElementById("myDiv").getElementsByTagName("img"),
    arr = [];

for (var i = 0; i < imgs.length; i++) {
    arr.push(imgs[i].src);
}

console.log(arr);

jQuery solution:

var arr = $("#myDiv img").map(function() {
    return this.src;
}).get();

console.log(arr);
