    var len = firstoptionElement.length; 
    for(var i=0;i<len;i++){ 
        if(firstElement.selectedIndex != -1){ //selectedIndex 是select 的属性 
        secondElement.appendChild(firstoptionElement[firstElement.selectedIndex]); 
        } 
    } 
} 
//全部移动到右边 
function alltarget(targetl , targetr){ 
    var firstElement = document.getElementById(targetl); 
    var secondElement = document.getElementById(targetr); 
    var firstoptionElement = firstElement.getElementsByTagName("option"); 
    var len = firstoptionElement.length;

// 针对分页checkbox选中问题
var checkArrayNum = [];// 存储所有选中的checkbox
var pageSize = 2;// 每页显示数量
var checkArray = function(pageNum) {// pageNum当前页

    var j = 1;
    // 记录当前页信息
    for (var i = (count - pageSize); i < count; i++) {// 遍历当前页
        if ($("[name='check']")[j - 1] != undefined) {

            if ($("[name='check']")[j - 1].checked) {
                checkArrayNum[i] = $("[name='check']")[j - 1].value;
            } else {
                checkArrayNum[i] = null;
            }
            j++;
        }
    }

}
// 当前页
var nowArray = function(nextPageNum) {
    var nextCount = pageSize * nextPageNum;
    var n = 1;
    if ($("#sla").is(":checked") == false) {
        for (var i = (nextCount - pageSize); i < nextCount; i++) {// 遍历当前页
            if (checkArrayNum[i] != null) {
                $($("[name='check']")[n - 1]).attr("checked", true);
            } else {
                $($("[name='check']")[n - 1]).attr("checked", false);
            }
            n++;
        }
    } else {
        for (var i = (nextCount - pageSize); i < nextCount; i++) {// 遍历当前页
            $($("[name='check']")[n - 1]).attr("checked", true);
