复制代码 代码如下: <script language="javascript"> function showlist(vtype) { with (document.listform) { w_type.value=vtype; } document.listform.submit(); return; } function showout(vid) { with (document.showform) { id.value=vid; } document.showform.submit(); return; } function showmenu(buyok,img) { if(buyok.style.display=="none") { buyok.style.display=""; img.src="images/bclass2.gif"; } else { buyok.style.display="none"; img.src="images/bclass1.gif"; } } </SCRIPT> <script language="JavaScript"> function page(vpage){ document.pageform.page.value=vpage; document.pageform.submit(); return false; }
function trimpos(s) { return s.replace(/(^[\s]*)|([\s]*$)/g, ""); }
function isnum( tmp ){ if ( tmp >= '0' && tmp <= '9' ) return true; return false; }
function mysubmit(){ if (event.keyCode=='13') gosubmit(); }
function gosubmit(){ var str=trimpos(vpos.value); if (str == "") { alert("请输入页码!"); vpos.focus(); return; } for ( var i=0; i < str.length; i++ ){ if(isnum( str.charAt(i)) == false){ alert("页码必须由数字组成!"); vpos.focus(); vpos.value=""; return; } } if ( ( parseInt(str)<1 ) || ( parseInt(str) > 2) ){ alert("页码超出范围!"); vpos.focus(); vpos.value=""; return; } page(str); }
</script>
