由于Asp.Net Mvc 不支持ViewState，也不支持Asp.net Ajax服务器端控件，导致以前写的部门选择控件不能正常使用，搜索jquery的插件也没找到可以使用的插件，所以自己动手写一个jquery.popup插件
完整源代码及示例下载：jquery.popup.rar
下拉框选择控件，该插件需要引用jquery.dimensions插件，结合jquery.treeview可以支持树状结构的下拉框
先看看效果如下：
jquery.popup.js代码如下：
/* $Id: jquery.popup.js 67 2008-01-22 08:54:37Z Bolik@xjgc.com $ */(function($) { function Popup(el, content) { this.input = $(el); this.popupContent = content;this.input.attr("readonly", "readonly");
this.bindMethodsToObj("show", "hide", "hideIfClickOutside", "selectItem");
this.build(); //this.selectItem(); this.hide();};
Popup.prototype = { build: function() {this.ClearController = $('<a href="#">clear</a>').click(this.bindToObj(function(event) {
this.selectItem("", "");
this.hide();return false;
}));
this.popupController = $('<div class="popupController"></div>').append(this.ClearController);
this.popupContent = $('<div class="popupContent"></div>').append(this.popupContent);
this.popupPanel = this.rootLayers = $('<div class="popupPanel"></div>')
.css({ display: "none", position: "absolute", zIndex: 100 }).append(this.popupController, this.popupContent)
.appendTo(document.body);
if ($.browser.msie && $.browser.version < 7) {this.ieframe = $('<iframe class="popupPanel_ieframe" frameborder="0" src="#"></iframe>')
.css({ position: "absolute", display: "none", zIndex: 99 }) .insertBefore(this.popupPanel);this.rootLayers = this.rootLayers.add(this.ieframe);
};
$("a", this.popupContent).click(this.bindToObj(function(event) {
this.selectItem($(event.target).attr("id"), $(event.target).attr("innerHTML"));
this.hide();return false;
}));
//this.input.change(this.bindToObj(function() { this.selectItem(); }));},
selectItem: function(item, text) { this.selectedItem = item;this.input.attr("SelectedItem", item);
this.input.val(text); },
show: function() { this.setPosition();this.rootLayers.css("display", "block");
this.input.unbind("focus", this.show);
$(document.body).click(this.hideIfClickOutside);},
hide: function() {this.rootLayers.css("display", "none");
$(document.body).unbind("click", this.hideIfClickOutside);
this.input.focus(this.show);
},
hideIfClickOutside: function(event) {
if (event.target != this.input[0] && !this.insideSelector(event)) {
this.hide();};
},
setPosition: function() {var offset = this.input.offset();
this.rootLayers.css({ top: offset.top + this.input.outerHeight(),left: offset.left
});
if (this.ieframe) {
this.ieframe.css({ width: this.popupPanel.outerWidth(), height: this.popupPanel.outerHeight()});
};
},
insideSelector: function(event) {
var offset = this.popupPanel.offset();
offset.right = offset.left + this.popupPanel.outerWidth(); offset.bottom = offset.top + this.popupPanel.outerHeight();return event.pageY < offset.bottom &&
event.pageY > offset.top && event.pageX < offset.right && event.pageX > offset.left;},
bindToObj: function(fn) {var self = this;
return function() { return fn.apply(self, arguments) };
},
bindMethodsToObj: function() {for (var i = 0; i < arguments.length; i++) {
this[arguments[i]] = this.bindToObj(this[arguments[i]]);
};
}
};
$.fn.popup = function(content) {return this.each(function() {
new Popup(this, content);
});
};
})(jQuery);
