jQuery和评估

Question

First of all, lets say I have about 10 divs that are hidden and have the ID's as "modal1", "modal2", "modal3", etc... Using an ajax request, the data returned contains an ID number, lets say it is 7.

In previous tasks, I have used the javascript eval function but this does not work. I wish to append the received data to the correct modal div.

var newdataobj = JSON.parse(newdata);
var ResponseDiv = "#modal" + newdataobj.ID;
$(eval(ResponseDiv)).append(newdataobj.DataToAdd);

This doesn't work and the script stops working at this point. I have also tries using the JQuery version of eval, but that did not work either.

Answer 1

ResponseDiv is already a string containing exactly what you want.
You don't want eval at all.
