## 获取字符串的字节长度
function getStringMemorySize(_string) {
    "use strict";
    var codePoint, accum = 0;
    for (var stringIndex = 0, endOfString = _string.length; stringIndex < endOfString; stringIndex++) {
        codePoint = _string.charCodeAt(stringIndex);

        if (codePoint < 0x100) {
            accum += 1;
            continue;
        }

## 匹配汉字


然后把范围扩大到^[\u2E80-\u9FFF]+$, 这样倒是都通过了, 这个应该就是匹配中日韩文字的正则表达式了, 包括我們臺灣省還在盲目使用的繁體中文

而关于中文的正则表达式, 应该是^[\u4E00-\u9FFF]+$, 和论坛里常被人提起的^[\u4E00-\u9FA5]+$很接近


这里是几个主要非英文语系字符范围

## 复制html标签属性
function cloneImg (elem) {
		var imgNode = document.createElement("div");
		var attributes = elem.attributes;
		for (var i in attributes) {
			if(!attributes.hasOwnProperty(i)) {
				continue;
			}
			var attr = attributes[i];
			if(attr.name == 'class') {
				imgNode.className = attr.value;

## 递归
// returns true if the element or one of its parents has the class classname
function hasSomeParentTheClass(element, classname) {
    if (element.className.split(' ').indexOf(classname)>=0) return true;
    return element.parentNode && hasSomeParentTheClass(element.parentNode, classname);
}
