How could I make it that if someone clicks the image of the selected product to change the url of the button under the images
<div id="product">
<img value="1" src="http://placehold.it/300x100?text=Mary+Jane" alt="" />
<img value="2" src="http://placehold.it/300x100?text=LSD" alt="" />
<img value="3" src="http://placehold.it/300x100?text=Crack" alt="" />
</div>
<br>
<a id="buy" href="#"><button>Go to the the specific link</button></a>
text/image for amusement only, they are not really the products
What I have tried
window.onload = function() {
var sel = document.getElementById('product');
sel.onchange = function() {
document.getElementById("buy").href = "https://amazon.com/" + this.value;
}
}
Here's a codepen http://codepen.io/anon/pen/bdyWGa
Jquery solution:
$(function(){
$("img").click(function(){
$("#buy").attr("href","https://amazon.com/"+$(this).attr("value"));
});
});
Javascript Version:
var images = document.getElementsByTagName("img");
for (var i=0, len=images.length, img; i<len; i++) {
img = images[i];
img.addEventListener("click", function() {
document.getElementById("buy").setAttribute("href", "https://amazon.com/"+ this.getAttribute("value"));
alert("New href value: " + "https://amazon.com/"+ this.getAttribute("value"));
});
}
<img id="img1" src="http://placehold.it/300x100?text=Mary+Jane" alt="" />
<img id="img2" src="http://placehold.it/300x100?text=LSD" alt="" />
<img id="img3" src="http://placehold.it/300x100?text=Crack" alt="" />
<br>
<a id="buy" href="#"><button>Go to the the specific link</button></a>
and:
$("#img1").on("click", function(){
$("#buy").attr("href","https://mynewurl.net");
});
here you describe clicking on which img will change url to what
In javascript. Use e.target
for take the current click element and get the value using attrubutes and apply to the href attribute.
window.onload = function() {
var sel = document.getElementById('product');
sel.onclick = function(e) {
console.log( e.target.attributes[0].value)
document.getElementById("buy").setAttribute('href', "https://amazon.com/" + e.target.attributes[0].value) ;
}
}
Use jQuery to add a click event to all images to fetch the property value and add as an addition to href property of the intended element
$(function(){ $('img').on('click', function(){ $('#buy').attr('href',"https://amazon.com/" + $(this).attr('value')); }); }
