一、效果如下
二、js代码
$("body").on("click", "#btn_print", function () {
assessRankQueryPrint();
});
function assessRankQueryPrint(){
var value_columns1 = ["考核年度","被考核人员","单位","岗位","专职","第一季度","第一季度","第二季度","第二季度","第三季度","第三季度","第四季度","第四季度","备注"];
var key_columns2 = ["year_","name_user","name_org","name_postduty","label","info01","info02","info04","info05","info07","info08","info10","info11","remarks"];
var value_columns2 = ["考核年度","被考核人员","单位","岗位","专职","考核得分","本周期岗位排名","考核得分","本周期岗位排名","考核得分","本周期岗位排名","考核得分","本周期岗位排名","备注"];
var url = "jee/VAssessQuarterRankQueryC/exportExecl?key_columns2="+key_columns2+"&value_columns1="+value_columns1+"&value_columns2="+value_columns2;
window.location.href= url;
