JavaScript - Loop over all a tags, add an onclick to each one
- by tripRev
I've got a list of links that point to images, and a js function that takes a URL (of an image) and puts that image on the page when the function is called.
I was originally adding an inline onlick="showPic(this.getAttribute('href'))" to each a, but I want to separate out the inline js. Here's my func for adding an onclick to each a tag when the page loads:
function prepareLinks(){
var links = document.getElementsByTagName('a');
for(var i=0; i<links.length; i++){
var thisLink = links[i];
var source = thisLink.getAttribute('href');
if(thisLink.getAttribute('class') == 'imgLink'){
thisLink.onclick = function(){
showPic(source);
return false;
}
}
}
}
function showPic(source){
var placeholder = document.getElementById('placeholder');
placeholder.setAttribute('src',source);
}
window.onload = prepareLinks();
...but every time showPic is called, the source var is the href of the last image. How can I make each link have the correct onclick?
