function initView(_box){
	var $p = $(_box || document);
	
	$('a[target="dialog"]',$p).each(function(event){
		$(this,$p).unbind('click').click(function(event){
			openModal(event);
		});
	});
}
$(function(){
	initView();
});

/**关闭modal*/
function hideModal(obj){
	var modal = $(obj).parents("div.modal");
	if(modal.length > 0){
		modal.remove();
		initView();
	}
}
/**打开modal*/
function openModal(event){
//	var this = $(this);
	var $this = $(event.currentTarget);
	var _url = $this.attr("href");
	var _title = $this.attr("title");
	var _id;
	
	_id = dialog.content();
	
	var options = {
			backdrop: false,keyboard: true,show: true
	};
	$('#' + _id).modal(options);
	var modal = $('#' + _id);
	if(typeof(_title) != "undefined"){
