jQuery中多个元素的Hover事件解决方案

<script type=”text/javascript” src=”js/jquery.js”></script>
<script type=”text/javascript” src=”js/jquery.mixhover.js”></script>

控制代码

$.mixhover(
‘#trigger’,
‘#drop’,
function(trg, drop){
#(drop).show();
},
function(trg, drop){
#(drop).hide();
}
)

这样当鼠标进入#trigger时将#drop显示出来，鼠标从#trigger移如#drop时不会触发任何事件，实际上就是讲#trigger和#drop元素当做一个元素来处理。
jquery.mixhover.js程序如下

$.mixhover = function() {
// 整理参数 $.mixhover($e1, $e2, handleIn, handleOut)
var parms;
var length = arguments.length;
var handleIn = arguments[length – 2];
var handleOut = arguments[length – 1];
if ($.isFunction(handleIn) && $.isFunction(handleOut)) {
parms = Array.prototype.slice.call(arguments, 0, length – 2);
} else if ($.isFunction(handleOut)) {
parms = Array.prototype.slice.call(arguments, 0, length – 1);
handleIn = arguments[length – 1];
handleOut = null;
} else {
parms = arguments;
handleIn = null;
handleOut = null;
}
// 整理参数 使得elements依次对应
var elems = [];
for (var i = 0, len = parms.length; i < len; i++) {
elems[i] = [];
var p = parms[i];
if (p.constructor === String) {
p = $(p);
}
if (p.constructor === $ || p.constructor === Array) {
for (var j = 0, size = p.length; j < size; j++) {
elems[i].push(p[j]);
}
} else {
elems[i].push(p);
}
}
// 绑定Hover事件
for (var i = 0, len = elems[0].length; i < len; i++) {
var arr = [];
for (var j = 0, size = elems.length; j < size; j++) {
arr.push(elems[j][i]);
}
$._mixhover(arr, handleIn, handleOut);
}
};
$._mixhover = function(elems, handleIn, handleOut) {
var isIn = false, timer;
$(elems).hover(function() {
window.clearTimeout(timer);
if (isIn === false) {
handleIn && handleIn.apply(elems, elems);
isIn = true;
}
},
function() {
timer = window.setTimeout(function() {
handleOut && handleOut.apply(elems, elems);
isIn = false;
}, 10);
});
};
