表单提交后如何在文本框值中设置值？

我正在使用这个 js 块，但我仍然无法在文本框或 div 中存储值

<script type="text/javascript">

(function($,W,D)

    JQUERY4U.UTIL =

                    wsnString = _wsnDate+'_'+_wsndescription+'_'+_wsnCRS+'_$'+_wsnCost;
                    //Session["wsnvalues"] = wsnString;
                    //window.location.href = 'page2.html';

                    alert(wsnString);


                    //window.location.href = 'page2.html';
                }
            });
        }
    }

    //when the dom has loaded setup form validation rules
    $(D).ready(function($) {
        JQUERY4U.UTIL.setupFormValidation();
    });

})(jQuery, window, document);
</script>

我想将wsnString的值设置为一个文本框或 div，我可以在其中复制生成的文本。这可能吗？

Answer 1

$('#mytextbox').val(wsnString).
