----------------------对于动态的标签绑定事件------------------------

复制代码 代码如下:

var outTimer;//执行时间
var upTimer;//执行时间
var sqDiv = $("#tm");//要显示的div
var test="";//标识,为了将鼠标移到显示的div上时,div不会消失
var dd = "";//划过某一字段传的值
function test1(){
$("#tm").empty();//现将div清空
$.ajax({ //往里加数据
type:"post",
url:"/webmodule/constructionDecision/BaseCD/getCommunityInfo.do?stCode="+dd,
dataType:"json",
async:false,
success:function(data){
var td="";
for(var i=0;itd+=""+data[i].name+"";
}
$("#tm").append(td);
}
});
$("#tm").show();
}

function test2(){//隐藏div的方法
if(test ==""){
$("#tm").hide();
}
}
$("#cityTable a").die().live('mouseover mouseout', function(event) { //给动态标签绑定事件

if(event.type=='mouseover'){ //移上时
clearTimeout(outTimer);//先清空移出的时间,这样能避免鼠标划过就执行函数,减轻服务器的压力
dd=$(this).attr("id");
upTimer = setTimeout(test1, 500);//0.5秒后再执行
}
if(event.type=='mouseout'){
sqDiv.hover(
function(){
test = "on";//说明鼠标在显示的div上
},function(){
test = "";
test2();
});
clearTimeout(upTimer);
outTimer = setTimeout(test2, 500);
}
});

----------------------------非动态标签(查询资料)-----------------------------------
复制代码 代码如下:

//hoverDuring 鼠标经过的延时时间
//outDuring 鼠标移出的延时时间
//hoverEvent 鼠标经过执行的方法
//outEvent 鼠标移出执行的方法
$( function() {
$.fn.hoverDelay = function(options) {
var defaults = {
hoverDuring :200,
outDuring :200,
hoverEvent : function() {
$.noop();
},
outEvent : function() {
$.noop();
}
};
var sets = $.extend(defaults, options || {});
var hoverTimer, outTimer;
return $(this).each( function() {
$(this).hover( function() {
clearTimeout(outTimer);
hoverTimer = setTimeout(sets.hoverEvent, sets.hoverDuring);
}, function() {
clearTimeout(hoverTimer);
outTimer = setTimeout(sets.outEvent, sets.outDuring);
});
});
}

复制代码 代码如下:

//$("#sosoFod h3").each( function() {
$("#sosoweb").each( function() {
var test = "";//当test为空时,鼠标移到字段显示div,移出隐藏div
var that = $(this);
var id = that.attr("id");
var div = $("#tm");
div.css("position", "absolute");//让这个层可以绝对定位
that.hoverDelay( {
outDuring :1000,
hoverEvent : function() {
div.css("display", "block");
var p = that.position(); //获取这个元素的left和top
var x = p.left + that.width();//获取这个浮动层的left
var docWidth = $(document).width();//获取网页的宽
if (x > docWidth - div.width() - 20) {
x = p.left - div.width();
}
div.css("left", x);
div.css("top", p.top);
//$("#tm").show();

},
outEvent : function() {

$("#tm").hoverDelay( {
outDuring :1000,
hoverEvent : function() {
test = "on";
$("#tm").show();
},
outEvent : function() {
test="";
$("#tm").hide();
}
});
if(test==""){
$("#tm").hide();
}
}
});
});
