【问题描述】:
我使用 Jquery 创建了一个运行良好的 javascript 上下文菜单。但是有两种选择。第一个是在 C# 中创建这个上下文菜单(如果可能的话)。第二种方法是在单击菜单中的按钮时运行 C# 函数。哪个选项是最好的,我该如何开始?亲切的问候
Javascript:
function Menu($div){
var that = this,
ts = null;
this.$div = $div;
this.items = [];
// create an item using a new closure
this.create = function(item){
var $item = $('<div class="item '+item.cl+'">'+item.label+'</div>');
$item
// bind click on item
.click(function(){
if (typeof(item.fnc) === 'function'){
item.fnc.apply($(this), []);
}
})
// manage mouse over coloration
.hover(
function(){$(this).addClass('hover');},
function(){$(this).removeClass('hover');}
);
return $item;
};
this.clearTs = function(){
if (ts){
clearTimeout(ts);
ts = null;
}
};
this.initTs = function(t){
ts = setTimeout(function(){that.close()}, t);
};
}
// add item
Menu.prototype.add = function(label, cl, fnc){
this.items.push({
label:label,
fnc:fnc,
cl:cl
});
}
// close previous and open a new menu
Menu.prototype.open = function(event){
this.close();
var k,
that = this,
offset = {
x:0,
y:0
},
$menu = $('<div id="menu"></div>');
// add items in menu
for(k in this.items){
$menu.append(this.create(this.items[k]));
}
// manage auto-close menu on mouse hover / out
$menu.hover(
function(){that.clearTs();},
function(){that.initTs(3000);}
);
// change the offset to get the menu visible (#menu width & height must be defined in CSS to use this simple code)
if ( event.pixel.y + $menu.height() > this.$div.height()){
offset.y = -$menu.height();
}
if ( event.pixel.x + $menu.width() > this.$div.width()){
offset.x = -$menu.width();
}
// use menu as overlay
this.$div.gmap3({
action:'addOverlay',
latLng: event.latLng,
content: $menu,
offset: offset
});
// start auto-close
this.initTs(5000);
}
// close the menu
Menu.prototype.close = function(){
this.clearTs();
this.$div.gmap3({action:'clear', name:'overlay'});
}
