js源码
$(function(){
$(‘.btn.remove‘).click(function(){
if(confirm("确定要删除页面吗？")) {
$(this).parent().detach();
}
});
var dropable = $(‘#dropzone‘).droppable({
activeClass : ‘active‘,
hoverClass : ‘hover‘,
accept : ":not(.ui-sortable-helper)"
});
dropable.sortable({
items : ‘.drop-item‘,
sort : function() {
$(this).removeClass("active");
}
});
$(‘#report_page_save_btn‘).click(function(){
save();
});
$(‘#report_page_def_btn‘).click(function(){
if(confirm("确定要恢复页面数据吗？")) {
set_def();
}
});
});
使用其他第三方js结构如下。其实就只有使用了jquery-ui
另一个简单案例
