未用javascript
qq分享菜单.png
使用javascript后
qq分享菜单拉出.png
代码如下
function share(){
var isOpen = false;
var $shareMore = $('#shareMore');
var $parent = $shareMore.parent();
var $as = $shareMore.prevAll('a:lt(2)');
var $b = $shareMore.children();
$shareMore.click(function() {
if(isOpen){
$parent.css('width', 155);
$as.hide();
$b.removeClass('backword');
}else{
$parent.css('width', 200);
$as.show();
$b.addClass('backword');
}
isOpen = !isOpen;
});
}
