The Alt attribute is in the case of img tags do not have pictures of the default display content,

Can add Alt, belongs to the div tags, is not the same as you understand the img Alt, for example:

 
Content

 
$(function () {
$(" all "). Attr (" Alt ", "123") 
});

$(function () {

}); 

Add can certainly add, is that there is no img that the role of the default content, if you're going to be a custom attribute, does not recommend using this in the original of the same name, there will be ambiguity
