Answer 1

修改your handleSubmit function如下:

function handleSubmit()
{
    var form = _gel("moduleForm"),
        elm = _gel("allQuery"),
        selectElm = _gel("allSelect");
    if (elm != "" && selectElm != "") {
        var query = elm.value;
        var searchUrl = selectElm.value;
        if (query != "" && searchUrl != "") {
            searchUrl += escape(query);
            window.open(searchUrl, form.target || "_blank");
        }
    }
    return false;
}
