IE8下DIV嵌套高度自适应
IE8在默认情况下不会对DIV进行高度自适应,而IE6、7下设置DIV高度为auto即可自适应高度;解决方法:父DIV的CSS设置display:table\0;即可使其随内部嵌套DIV高度自适应。
第二代身份证号码的验证机制
如下JS代码进行二代身份证验证(代码转载自盛大网络):
iW = new Array(7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2,1); iSum = 0; for( i=0;i<17;i++){ iC = v_card.charAt(i) ; iVal = parseInt(iC); iSum += iVal * iW[i]; } iJYM = iSum % 11; var sJYM = ''; if(iJYM == 0) sJYM = "1"; else if(iJYM == 1 ) sJYM = "0"; else if(iJYM == 2 ) sJYM = "x"; else if(iJYM == 3 ) sJYM = "9"; else if(iJYM == 4 ) sJYM = "8"; else if(iJYM == 5 ) sJYM = "7"; else if(iJYM == 6 ) sJYM = "6"; else if(iJYM == 7 ) sJYM = "5"; else if(iJYM == 8 ) sJYM = "4"; else if(iJYM == 9) sJYM = "3"; else if(iJYM == 10) sJYM = "2"; var cCheck = v_card.charAt(17).toLowerCase(); if( cCheck != sJYM ){ return false; //对不上就是假号码 }
打开网页时提示 Stack overflow at line: 0
打开京东或淘宝网站时,经常会弹出JS错误提示Stack overflow at line: 0;
初步分析,可能是由于页面所含图片文件太多,部分图片未正确加载导致出现该错误,查看图片调用代码,大致如下:
<script type=”text/javascript”>
<!–
function noexist(){
var img=event.srcElement;
img.src=”nopic.gif”;
img.onerror=null; //清除该事件
}
//–>
</script>
