判断鼠标焦点function addListener(element, e, fn) {
if (element.addEventListener) {
element.addEventListener(e, fn, false)
} else {
element.attachEvent("on" + e, fn)
}
}
addListener(document, "click", function (evt) {
var evt = window.event ? window.event : evt, target = evt.srcElement || evt.target
if (target.id == "div") {
//焦点在“div”中
return
} else {
//
}
})
var Apdiv=document.getElementById("apDiv1s")Apdiv.focus()
或者 在body
<body onload="document.form名.你想获取焦点的那一个属性名.focus()">
<body onload="document.form1.input1.focus()">
<form name="form1">
<imput name="input1"/>
</form>
</body>
