记得引用jquery 类库

代码如下:

$(document).ready(function () {
if ($.browser.msie)
$("input:text,input:password").each(function () {
var $placeholder = $(this).attr("placeholder");
var $width = $(this).css("width");
var $id = $(this).attr("id");
var $height = parseInt($(this).css("height")) 6 "px";
var $fontSize = $(this).css("font-size");
var $fontWeight = $(this).css("font-weight");
var $lineHeight = $height;
if ($(this).css("line-height") != "normal") {
$lineHeight = parseInt($(this).css("line-height")) 6 "px";
}
if ($placeholder != undefined) {
$(this).after("" $placeholder "");
}
$(this).bind("keyup", function () {
if ($(this).val() == "") {
$(this).parent().find(".ph_" $id).css("display", "inline-block");
}
else {
$(this).parent().find(".ph_" $id).css("display", "none");
}
});
});
$(".placeholder").live("click", function () {
$(this).prev().focus();
});
});
