Question

我有一个J2EE Web应用程序的问题，我需要能够修改单元格的内容并将修改保存在数据库中，我在Chrome上找到了具有contenteditable和XMLHttpRequest的解决方案，但这个解决方案似乎没有每当我尝试保存修改时，在Internet Explorer上工作我都会收到此错误：

INFOS: Error parsing HTTP request header
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.
java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

获取修改以将其保存在数据库中的函数是：

function MajFD(id_table, compteur){
                    var nouvelleValeur = document.getElementById('descFD' + compteur).innerHTML.replace(/&lt;br\s*\/&gt;/g,'<br/>');
                    var xhttp = new XMLHttpRequest();
                    xhttp.open("GET","<%=request.getContextPath()%>/action/UpdateDesc.action?id_table=" + id_table + " &nouvelleDescription=" 
                            +  nouvelleValeur, true);
                    valuesFD[compteur] = nouvelleValeur;
                    xhttp.send();
                    document.getElementById('ModifierFD' + compteur).setAttribute('style','display: none;');
                    document.getElementById('cancelFD' + compteur).setAttribute('style','display: none;');
                }
