Question

I am sending a string down from a websockets server to my client that has a jqgrid on it.

the string is a JSON object which I”m converting using eval() (I know that’s not best practice, but this is just for a proof of concept at this point).

I’m just trying to reload the jqgrid with:

var obj = eval("(" + msg.data + ")");
$("#list").setGridParam({ "postData" : obj }).trigger("reloadGrid");

where msg is the parameter in my socket.onmessage callback, if I alert (msg.data), I see my correctly formed JSON string, but my grid isn’t reloading.

if I alert obj, I see that it’s converting to an object correctly.

I also tried splitting out the trigger(“reloadGrid”) onto a separate line with my $(“#list) prepending it…still not reloading.

any suggestions?

If you use datatype: 'jsonstring' and datastr: msg.data and you want reload the grid with another data you should understand that datatype: 'jsonstring' will be changed to datatype: 'jsonstring' after the first load. The postData parameter will be used only if you communicate with the server. In the case the datatype must be either 'json' or 'xml'. The url parameter should be set in the case too.

So I you can try to do the following:

$("#list").setGridParam({
    datatype: 'jsonstring', // reset the `datatype`
    datastr: msg.data       // set new value of the input data
}).trigger("reloadGrid");
