Js ajax request problem.

in the project, request background data through ajax and do data processing. Finally, the processed data will be returned. The code looks like this: 

function funOne(){
    var htmlStr = "";
    $.get(href,{},function(r){
        var data = eval("(" + r + ")");
        $.each(data,function(k,v){
            /*     */
            htmlStr += "<div>" + v + "</div>";
        })
    })
    return htmlStr;
}
