常用JS脚本（手机、SHA1加密、日期比较、省市联动）

如题：　　

　　1、JS手机验证

　　　　

//true  通过
function isMobile(value) 
{
    if (/^13\d{9}$/g.test(value) || (/^15[0-35-9]\d{8}$/g.test(value)) || (/^18[05-9]\d{8}$/g.test(value))) { 
    return true; }
    else {
     return false; }
}

　　2、JS加密SHA1算法

　　　　试验了hex_sha1方法，和C#端如下代码返回一致（需要转化下大小写）

　　　　

 System.Text.Encoding rr = System.Text.Encoding.ASCII;
                    byte[] data = rr.GetBytes(name);//以字节方式存储
                                      StringBuilder sb = new StringBuilder();
                    foreach (byte b in System.Security.Cryptography.SHA1.Create().ComputeHash(data))
                    { sb.Append(b.ToString("X2")); }
                    string res = sb.ToString();

　　3、JS时间比较

　　　　

//比较日期大小   
function compareDate(checkStartDate, checkEndDate) {
    var arys1 = new Array();
    var arys2 = new Array();
    if (checkStartDate != null && checkEndDate != null) {
        arys1 = checkStartDate.split('-');
        var sdate = new Date(arys1[0], parseInt(arys1[1] - 1), arys1[2]);
        arys2 = checkEndDate.split('-');
        var edate = new Date(arys2[0], parseInt(arys2[1] - 1), arys2[2]);
        if (sdate > edate) {
           // alert("日期开始时间大于结束时间");
            return true;
        } else {
            //alert("通过");
            return false;
        }
    }
}

//判断日期，时间大小   
function compareTime(startDate, endDate) {
    if (startDate.length > 0 && endDate.length > 0) {
        var startDateTemp = startDate.split(" ");
        var endDateTemp = endDate.split(" ");

        var arrStartDate = startDateTemp[0].split("-");
        var arrEndDate = endDateTemp[0].split("-");

        var arrStartTime = startDateTemp[1].split(":");
        var arrEndTime = endDateTemp[1].split(":");

        var allStartDate = new Date(arrStartDate[0], arrStartDate[1], arrStartDate[2], arrStartTime[0], arrStartTime[1], arrStartTime[2]);
        var allEndDate = new Date(arrEndDate[0], arrEndDate[1], arrEndDate[2], arrEndTime[0], arrEndTime[1], arrEndTime[2]);

        if (allStartDate.getTime() >= allEndDate.getTime()) {
           // alert("startTime不能大于endTime，不能通过");
            return true;
        } else {
            //alert("startTime小于endTime，所以通过了");
            return false;
        }
    } else {
        alert("时间不能为空");
        return true;
    }
}
//比较日期，时间大小   
function compareDateTime(startDate, endDate) {
    if (startDate.indexOf(" ") != -1 && endDate.indexOf(" ") != -1) {
        //包含时间，日期   
        return compareTime(startDate, endDate);
    } else {

        return compareDate(startDate, endDate);
    }
} 

　　4、Jquery的cookie操作

　　　　

jQuery.cookie = function (name, subName, value, options) {
    if (typeof value != 'undefined') { // name and value given, set cookie
        options = options || {};
        if (value === null) {

            var date;
            if (typeof options.expires == 'number') {
                date = new Date();
                date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));
            } else {
                date = options.expires;
            }
            expires = '; expires=' + date.toUTCString(); // use expires attribute, max-age is not supported by IE
        }
        // CAUTION: Needed to parenthesize options.path and options.domain
        // in the following expressions, otherwise they evaluate to undefined
        // in the packed version for some reason...
        var path = options.path ? '; path=' + (options.path) : ';path=/';
        var domain = options.domain ? '; domain=' + (options.domain) : '';
        var secure = options.secure ? '; secure' : '';

        //If value is an object, each property will be a sub key;
        if (typeof value == "object") {
            var k = 0;
            var tempResult = "";
            for (var tempValue in value) {
                if (k > 0) {
                    tempResult += "&";
                }
                tempResult += tempValue + "=" + encodeURIComponent(value[tempValue]);
                k++;
            }
            value = tempResult;
        }
        else {
            value = encodeURIComponent(value);
        }

        document.cookie = [name, '=', value, expires, path, domain, secure].join('');
    } else { // only name given, get cookie
        var cookieValue = null;
        if (document.cookie && document.cookie != '') {
            var cookies = document.cookie.split(';');
            for (var i = 0; i < cookies.length; i++) {
                var cookie = jQuery.trim(cookies[i]);
                // Does this cookie string begin with the name we want?
                if (cookie.substring(0, name.length + 1) == (name + '=')) {
                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));

                    //Search sub key
                    if (typeof subName != 'undefined' && subName != null && subName != "") {
                        var subCookies = cookieValue.toString().split('&');
                        for (var j = 0; j < subCookies.length; j++) {
                            var subCookie = jQuery.trim(subCookies[j]);
                            if (subCookie.substring(0, subName.length + 1) == (subName + '=')) {
                                cookieValue = decodeURIComponent(subCookie.substring(subName.length + 1));
                                break;
                            }
                        }
                    }

                    break;
                }
