這篇文章主要介紹了jQuery封裝的屏幕居中提示信息代碼,可以很方便的集成到項(xiàng)目開發(fā)中使用,涉及jQuery針對(duì)頁面元素的動(dòng)態(tài)操作技巧,需要的朋友可以參考下
本文實(shí)例講述了jQuery封裝的屏幕居中提示信息代碼。分享給大家供大家參考，具體如下：
代碼如下:
function showLoad(tipInfo, type, autohide) {
var pic = "";
switch (type) {
case 0: // loading
pic = "./Images/loading.gif";
break;
case 1: // ok
pic = "./Images/right.png";
break;
case 2: // error
pic = "./Images/error.png";
break;
default: //其他任何值時(shí)
pic = "./Images/loading.gif";
break;
}
var eTip = document.createElement('div');
eTip.setAttribute('id', 'tipDiv');
eTip.style.display = 'none';
eTip.style.width = '300px';
eTip.style.height = '20px';
eTip.style.padding = '5px 15px'
eTip.innerHTML = "<img src=\"" + pic + "\" style=\"float:left;\" /> <span style=\"color:#373737; font-size:14px\">" + tipInfo + "</span>";
try {
document.body.appendChild(eTip);
} catch (e) { }
$("#tipDiv").css({
position: "absolute",
border: "solid 0px #D1D1D1",
left: ($(window).width() - $("#tipDiv").outerWidth()) / 2,
top: ($(window).height() - $("#tipDiv").outerHeight()) / 2 + $(document).scrollTop()
});
$('#tipDiv').show();
if (autohide == true) {
$('#tipDiv').fadeOut(3000);
}
}
function closeLoad() {
$('#tipDiv').fadeOut();
}
代碼如下:

<html xmlns="http://www.w3.org/1999/xhtml">

<script type="text/javascript">
$(function () {
$("#name").blur(function () {
if ($(this).val() == "") {
tip(this, "×請(qǐng)輸入");
} else {
tip(this,"√輸入正確");
}
})
});
function tip(o,tip) {
var eTip = document.createElement("span");
var objid = $(o).attr("id") + "_tipDiv";
var value = $(o).val();
//絕對(duì)路徑
var x = $(o).offset().top;
var y = $(o).offset().left;
var w = $(o).width();
var h = $(o).height();
eTip.setAttribute("id", objid);
try {
document.body.appendChild(eTip);
} catch (e) { }
$("#" + objid).hide();
$("#" + objid).css({
top: x,
left: y + w + 10,
height: h,
position: "absolute",
padding: "5px"
});
$("#" + objid).html(tip);
$("#" + objid).show();
}
</script>
</head>
<body>
<br/><br/><br/><br/><br/>
<input type="text" id="name" /><br/><br/><br/><br/>
<input type="text" id="pwd" />
</body>
</html>
希望本文所述對(duì)大家jQuery程序設(shè)計(jì)有所幫助。
