js中的代码（红色代码为重点）：
$("#exportBtn").click(function () {
var attr = [];
if($("#allChoose").is(":checked")){
$("input[name='simChoose']").each(function () {
attr.push($(this).val());
});
}else{
$("input[name='simChoose']:checked").each(function () {
attr.push($(this).val());
});
}
console.log(attr);
if(attr.length<=0){
alert("请选择需要导出的数据...");
return;
}else{
//要提交到后台的数据
var ids = attr.join(",");
alert("数据导出完成");
var form = $("<form>");
form.attr('style','display:none');
form.attr('mothod','post');
form.attr('action',"${ctx!''}/goods/salesCapPrice/exportRecord.html");
//将要提交到后天的数据放到一个隐藏的input框中
var input1 = $('<input>');
input1.attr('type','hidden');
input1.attr('name','ids');
input1.attr('value',ids);
form.append(input1);
//另外一个需要提交的数据
var input2 = $('<input>')
input2.attr('type','hidden');
input2.attr('name','type');
input2.attr('value',2);
form.append(input2);
$('body').append(form);
form.submit(); //表单提交
}
});
