Get Src From Image Inside Button That You Have Clicked.

I am trying to get the SRC from an image inside a button that i have to press to open a accordion (bootstrap). What I want, is to get the src from the image that is inside the butt

Solution 1:

First don't use inline JavaScript. Instead bind to the element you need. Then use this, .find(), and .attr() to get the image's src property, $(this).find('img').attr('src'):

$('button.btn.btn-link').click(function() {
  console.log($(this).find('img').attr('src'))
})

#collapseimg {
  width: 15px;
}

Solution 2:

As IDs have to be unique in the document, you could simply use:

var button = document.getElementById("collapseimg");
var hrefVal = button.getAttribute("src");

If you have multiple buttons and you want to fetch the image within the clicked button (without using any IDs) you can do that via the click event.

var handleClick = function(event) {
    var buttonClicked = event.target;
    // using jQuery here, since mentioned in your tags:var imageSrc = $(buttonClicked).find("img").eq(0).attr("src");
}

And i have to concur with j08691. Don't use inline JS.
