如何调用JS函数,在web层实现 鼠标滑过imgbutton实现 img变成本地的附加的图片
function MM_swapImgRestore() { //v3.0
var i, x, a = document.MM_sr; for (i = 0; a && i < a.length && (x = a[i]) && x.oSrc; i++) x.src = x.oSrc;
}
function MM_preloadImages() { //v3.0
var d = document; if (d.images) {
if (!d.MM_p) d.MM_p = new Array();
var i, j = d.MM_p.length, a = MM_preloadImages.arguments; for (i = 0; i < a.length; i++)
if (a[i].indexOf("#") != 0) { d.MM_p[j] = new Image; d.MM_p[j++].src = a[i]; }
}
}
function MM_findObj(n, d) { //v4.01
var p, i, x; if (!d) d = document; if ((p = n.indexOf("?")) > 0 && parent.frames.length) {
d = parent.frames[n.substring(p + 1)].document; n = n.substring(0, p);
}
if (!(x = d[n]) && d.all) x = d.all[n]; for (i = 0; !x && i < d.forms.length; i++) x = d.forms[i][n];
for (i = 0; !x && d.layers && i < d.layers.length; i++) x = MM_findObj(n, d.layers[i].document);
if (!x && d.getElementById) x = d.getElementById(n); return x;
}
function MM_swapImage() { //v3.0
var i, j = 0, x, a = MM_swapImage.arguments; document.MM_sr = new Array; for (i = 0; i < (a.length - 2); i += 3)
if ((x = MM_findObj(a[i])) != null) { document.MM_sr[j++] = x; if (!x.oSrc) x.oSrc = x.src; x.src = a[i + 2]; }
}

上面函数实现的是图片变换
<asp:ImageButton ID="ImgeLogin" runat="server" OnClientClick="return MM_swapImgRestore() "
ImageUrl="~/Image/Login/OK按钮.gif" />
求高手解答 如何实现这个功能! 让imgbutton的图片变换 ! --------------------编程问答-------------------- 基本原理:发生onmouseover事件时,给ImageButton1.src="images/a.jpg";
用js操作。其他花哨的效果都是基于此基本原理的。 --------------------编程问答-------------------- 引用jquery.js,并设计两张图片,1.png和2.png
--------------------编程问答-------------------- 贴页面源文件.
<form id="form1" runat="server">
<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/1.png" />
<script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<script>
var obj = $('#<%=ImageButton1.ClientID %>');
obj.bind("mouseover", function () {
obj.attr("src", "2.png");
}).bind("mouseout", function () {
obj.attr("src", "1.png");
});
</script>
</form>
补充:.NET技术 , ASP.NET
