You can use setTimeout:
您可以使用setTimeout：
setTimeout(function()
{
if($('#MedHistoryGridSec').is(':visible'))
alert('yes');
else
alert('no');
}, 3000);

You could wrap up the code in a callback function and run it after three seconds using window.setTimeout:
您可以将代码封装在回调函数中，并在三秒钟后使用window.setTimeout：
var afterThreeSeconds = function() {
if ($("#MedHistoryGridSec").is(":visible")) {
alert("yes we have grid");
}
else{
alert("No Grid");
}
}
window.setTimeout(afterThreeSeconds, 3000);

Can you add a parameter to the medication history grid function taking a function containing the code you want executed after that function succeeds which you can then call at the end of the medication history grid function?
您是否可以向用药史网格函数添加一个参数，其中包含一个包含要在该函数成功后执行的代码的函数，然后您可以在用药史网格函数的末尾调用该函数？
