get 请求 请求参数超出请求链接最大数 解决办法

window.open("/order/export?ids=" + ids + "&type=" + type + "&clientid=" + clientId + "&areaid=" + area );

将get 请求改为表单post请求

var data = "ids=" + ids + "&type=" + type + "&clientid=" + clientId + "&areaid=" + area ;
creaForm("export", "/order/export", data, "_blank");

function creaForm(name, url, data, target) {
    var myform = null;
    var inputs, input;
    var datas = data.split("&");
    myform = $("<form></form>");
    $(myform).attr('name', name);
    $(myform).attr('action', url);
    if (target != undefined) $(myform).attr('target', target);
    $(myform).attr('method', 'post');
    $(datas).each(function (i) {
        inputs = datas[i].split("=");
        input = $("<input type='hidden' name='" + inputs[0] + "' />");
        input.val(inputs[1]);
        $(myform).append(input);
    });
    $(myform).css('display', 'none');
    $(myform).appendTo("body");
    $(myform).submit();
}
