对应JS方法:

复制代码 代码如下:

function listMove(main, follow, hidetextbox, isBack, index) {

if (index < 0)

return;

var o = undefined;

var source;

var distinct;

var dddd;

if (!isBack) {

//使用getElementById在IE6中存在BUG

source = $('#' + main);// window.document.getElementById(main);

distinct = $('#' + follow); //window.document.getElementById(follow);

}

else {

source = $('#' + follow); // window.document.getElementById(follow);

distinct = $('#' + main); // window.document.getElementById(main);

}

var hid = $('#' + hidetextbox)[0]; // document.getElementById(hidetextbox);

if (index != undefined) {

var op = "option:eq(" + index + ")";

source.find(op).each(function () {

distinct.append("<option value='" + $(this).val() + "'>" + $(this).text() + "</option>");

$(this).remove();

});

}

else {

source.find("option:selected").each(function () {

$(this).remove();

distinct.append("<option value='" + $(this).val() + "'>" + $(this).text() + "</option>");

});

}

var str = "";

//遍历Listbox，取得选中项的值

$('#' + main + ' option').each(function () {

str += $(this).val() + ',';

});

hid.value = str;

}
