Answer 8

TO:3楼的是不是重复了？ 
-----------
呵呵,那方法我写了三个重载,也不知道哪个好,效率不同,灵活程度不同.
使用很简单的,你只要传递几个参数而已.
直接跳转到第XX页是另外一段HTML+JS的.
<input type="text" id="txtTargetPage" class="CText"
            onkeypress="if (event.keyCode==13) {changePage('category.aspx?cat=<%=curCat %>',this.value);return false;}"
            onmouseover='this.focus()' /><input type="button" value="GO" class="CButton"
            onclick="changePage('category.aspx?cat=<%=curCat %>',txtTargetPage.value)" />[code]
[code=JScript]
function changePage(sUrlPrefix, sTargetPage){
    if(!isNaN(sTargetPage)) location.href=sUrlPrefix + "&page=" + sTargetPage;
}
