ColdFusion JavaScript等效于#encodeForJavaScript（）＃

我有几个表单字段，我通过ajax调用来更新数据库。数据库成功更新，但如果DoubleQuotes提交给数据库，我无法正确更新表单。ColdFusion JavaScript等效于#encodeForJavaScript（）＃

说Some "Quotes" are needed作为按Enter时的子任务提交。

DB将看到Some "Quotes" are needed。

但是，如果使用encodeURI(data.TASKDESCRIPTION)，则页面将在文本框的焦点处看到Some%20%22Quotes%22%20are%20needed。

如果页面刷新页面显示Some "Quotes" are needed成功。

<cfif isDefined("action") and action is "editSubtask"> 
    <cfquery name="udpateSubTask" datasource="#siteDataSource#"> 
     UPDATE ProjectTaskSubtasks 
     SET taskDescription = <cfqueryparam value="#form.TASKDESCRIPTION#" cfsqltype="cf_sql_varchar" > 
     WHERE guid = <cfqueryparam value="#form.SUBTASKGUID#" cfsqltype="cf_sql_varchar" > 
    </cfquery> 
    <cfquery name="selectSubTask" datasource="#siteDataSource#"> 
     SELECT guid as SUBTASKGUID, taskDescription 
     FROM ProjectTaskSubtasks 
     WHERE guid = <cfqueryparam value="#form.SUBTASKGUID#" cfsqltype="cf_sql_varchar" > 
     LIMIT 1 
    </cfquery> 
    <cfoutput>#serializeJSON(selectSubTask, "struct")#</cfoutput> 
    <cfabort> 
</cfif> 
<!--- ----------------------------------------- ---> 
<cfloop query="#subtasks#"> 
    <div id="_#subtasks.guid#" class="col-xs-12"> 
     <input type="text" id="description-#subtasks.guid#" name="description-#subtasks.guid#" class="#subtasks.isComplete is 0 ? '' : 'strike'# subtask-hide col-xs-10" value="#EncodeForHTMLAttribute(subtasks.taskDescription)#" onClick="allowInput(this)"/>

    </div> 
<!--- ----------------------------------------- ---> 
    <script> 
    var taskDescription_#subtasks.guid# = "#encodeForJavaScript(subtasks.taskDescription)#"; //this appears to work as needed 

    $('##description-#subtasks.guid#').keyup(function(e){ 
     var code = e.which; 
     if(code===13){ 
      $.post(
       '#cgi.SCRIPT_NAME#', 
       { 
        action: 'editSubtask', 
        SUBTASKGUID: $(this).parent()[0].id.replace('_',''), 
        TASKDESCRIPTION: $(this).val() 
       }, 
       function(data){ 
        data = JSON.parse(data); 
        data = data[0]; 

        taskDescription_#subtasks.guid# = encodeURI(data.TASKDESCRIPTION); //THIS DOES NOT WORK if doublequotes where submitted to the DB : when data comes back from editSubTask I need a way to update my Variable so on focus out it updates the field with the new information submitted . 
        $('##formButt').focus(); 
       } 
      ); 
     } 
    }); 

    $('##description-#subtasks.guid#').focusout(function(){ 
     /* .val(taskDescription_#subtasks.guid#)works great HERE on FocusOut doesn't change the Value from original var taskDescription_#subtasks.guid# = "#encodeForJavaScript(subtasks.taskDescription)#" */ 

     $('##description-#subtasks.guid#').val(taskDescription_#subtasks.guid#).removeClass('subtask').addClass('subtask-hide'); 
     setTimeout(function(){ 
      $('##delete-#subtasks.guid#').removeClass('subtask-cancel').addClass('subtask-cancel-hide'); 
     },150) 
    }); 
    </script> 
</cfloop>

不理解上下文@Dan。是的，它成功地进入了数据库，我只需要在它从Ajax调用返回后再次正确地在页面上显示它。特别是如果发送到数据库的内容有双引号。 – shaun

为什么你甚至编码值为taskDescription_#subtasks.guid#开始？

替换该行

taskDescription_#subtasks.guid# = encodeURI(data.TASKDESCRIPTION);

与

taskDescription_#subtasks.guid# = data.TASKDESCRIPTION;

而现在这条线

$('##description-#subtasks.guid#').val(taskDescription_#subtasks.guid#).removeClass('subtask').addClass('subtask-hide');

将正确设置新值。 jQuery的.val()完成了所有需要自动完成的事情。
