I'm creating buttons out of "tags" taken from my database. I'd like to add mouse event listeners to each button. However, the listener only seems to work on the last created button. Any ideas? Thanks.
var tagsContainer = document.getElementById('tags');
var tagarray = placetags.split(" ");
for (var tagcounter = 0; tagcounter < tagarray.length; tagcounter++){
var tag = document.createElement('input');
tag.type = 'button';
tag.value = tagarray[tagcounter];
tag.id = 'tagbutton';
tagsContainer.appendChild(tag);
tag.addEventListener('mouseover' , function(){
tag.style.color = 'white';
});
tag.addEventListener('mouseout' , function(){
tag.style.color = 'orange';
});
}
You need to change your handlers from this
tag.addEventListener('mouseover' , function(){
tag.style.color = 'white';
});
to this
tag.addEventListener('mouseover' , function(){
this.style.color = 'white';
});
Since with your original code, your handlers are closing over the tag variable, and so tag
ends up referring to the last button created.
