IntelliJ IDEA 工具grails实现多个文件压缩下载

$("#exportSelected").click(function(){
var checkbox = $("input[name='test']:checked");
//对checkbox进行判断是否进行选中，
if(checkbox.size() > 0){
var ids = ""
$(checkbox).each(function(){
ids +=  $(this).attr("id")+"|";//对选中的多个文件的id进行拼接
});

$("#ids").val(ids);
document.forms[0].action ="${createLink(controller: 'download', action: 'downloadMoreFile')}";
document.forms[0].submit();
} else {
window.alert("Please select at least one record to be exported!");
return;
}
});
});
