java jquery扩展（prototype）

JQUERY扩展方法有两种，一种是使用jquery.fn.extend,一种是jquery.extend 很好用

下面个实例：

<script type="text/javascript" src="jquery-1.6.2.js"></script>
<script type="text/javascript">
jQuery.fn.__toggleCheck = function (idPrefix) {
var c = false;
$(this).click(function () {
if (c) c = false;
else c = true;
$("input[type=checkbox][id^=" + idPrefix + "]").each(
function () {
this.checked = c;
}
);
});
};
jQuery.fn.__setRepeaterStyle = function (itemTag, evenStyle, hoverStyle) {
$("#" + this.attr("id") + " " + itemTag + ":odd").addClass(evenStyle);
var cssOriginal = "";
$("#" + this.attr("id") + " " + itemTag + "").mouseover(function () {
cssOriginal = $(this).attr("class");
$(this).addClass(hoverStyle);
});
$("#" + this.attr("id") + " " + itemTag + "").mouseout(function () {
$(this).removeClass();
if (cssOriginal.length > 0) {
$(this).addClass(cssOriginal);
}
});
};
</script>
<div id="selBox">
<input type="checkbox" id="a_1" />1
<input type="checkbox" id="a_2" />2
<input type="checkbox" id="a_3" />3
<input type="checkbox" id="a_4" />4
<input type="checkbox" id="a_5" />5
<input type="checkbox" id="a_6" />6
<input type="checkbox" id="a_All" />All</div>
<div id="a_All1">Check</div>
</div>
<style type="text/css">
table tr {}
table .rowStyle { background:#dedede;}
table .hoverStyle {font-weight:bold; color:Red; background-color:Gray;}
</style>
<table id="tb" style="width:100%; border:solid 1px #dedede;">

</tr>
</table>
<script type="text/javascript">

$("#a_All1").__toggleCheck("a_");
$("#tb").__setRepeaterStyle("tr", "rowStyle", "hoverStyle");
</script>
