Javascript对选择元素的内容进行排序

这将达到目的。只要将您的select元素传递给la：

document.getElementById('lstALL')

function sortSelect(selElem) {    var tmpAry = new Array();    for (var i=0;i<selElem.options.length;i++) {        tmpAry[i] = new Array();        tmpAry[i][0] = selElem.options[i].text;        tmpAry[i][1] = selElem.options[i].value;    }    tmpAry.sort();    while (selElem.options.length > 0) {        selElem.options[0] = null;    }    for (var i=0;i<tmpAry.length;i++) {        var op = new Option(tmpAry[i][0], tmpAry[i][1]);        selElem.options[i] = op;    }    return;}
