Question

我遇到了＆＃34; \ n＆＃34;即使在被告知不要复制时也要创建一条线。修复可能是一些简单的事情，我只是因为某种原因没有看到。我很感激对此问题的任何意见或指导。

（请仅给我Javascript答案，因为我对jquery或其他方法不感兴趣）

       <script type="text/javascript">

        if (pullDownResponseE == "")
        {
        }
        else {
        var pullDownValuesE = document.getElementById("taskOne");
        var pullDownResponseE = pullDownValuesE.options[pullDownValuesE.selectedIndex].value;
        stuffToCopy = stuffToCopy + "\n" + pullDownResponseE;
        }


        if (pullDownResponseF == "")
        {
        }
        else{
        var pullDownValuesF = document.getElementById("taskTwo");
        var pullDownResponseF = pullDownValuesF.options[pullDownValuesF.selectedIndex].value;
        stuffToCopy = stuffToCopy + "\n" + pullDownResponseF;
        }

        </script>

正如您所看到的，如果我的下拉值等于＆＃34;＆＃34;那么pullDownResponseF和pullDownReponseE应该什么都不做。并且这部分大部分都有效，它不会执行任何其他代码，除了新行＆＃34; \ n＆＃34;一部分。

有谁能解释这里出了什么问题？

编辑：拥有更多代码可能会有所帮助。我只会包含必要部分，因为它太长了。

        <script type="text/javascript">

        function copyNotesTemplate()

        {
        var stuffToCopy = "PT meets criteria" + "\n" + document.getElementById('myForm').value;
        }
        if(document.getElementById('noPtCriteria').checked)
        {
        var stuffToCopy = document.getElementById('noPtCriteria').value;
        }


        if (pullDownResponsee == "")

如果有人在此示例中跳过填写注释字段或跳过下拉列表，那么它将不会像我预期的那样执行代码，但在复制时会创建一个新行：

taskOne已选中

（因为任务2未被选中，因此这里有额外的行）

任务三选择

如果跳过任务2，我希望在第一和第三任务之间没有额外的一行。像这样：

taskOne已选中

任务三选择

注意：我知道有其他{}是没有意义的，但它在视觉上有所帮助。

如果您愿意，我可以在我的工具中复制/粘贴时创建完全正确的剪辑：

示例1：http://imgur.com/wGO5vnT

示例2：http://imgur.com/UX1tG5S

以下是我的html示例：

<html lang="en">
  What tasks are needed for the case?
  <br />
  <select class="style3" id="taskOne">
  <option value=""></option>
  <option value="ABN needed">ABN needed</option>
  <option value="Auth needed">Auth needed</option>
  </select>
  </html>

Answer 1

不，它不会添加新行，请参阅：

stuffToCopy = "";
controlGroup = "a\nb";
pullDownResponseE = "";

if (pullDownResponseE == "")
{
}
else {
    var pullDownValuesE = "taskOne";
    var pullDownResponseE = "value";
    stuffToCopy = stuffToCopy + "\n" + pullDownResponseE;
}
alert("stuffToCopy:"+stuffToCopy+";(no new-line here)\ncontrolGroup:"+controlGroup);

我的猜测是你的html打印得很远，你从输入中获得的值最后会包含一个额外的换行符。尝试将html更改为1行，不使用换行符，然后再次测试。

而不是：

<option value="a
">b
</option>

尝试：

<option value="a">b</option>

Answer 2

好吧所以我修复了它，应该使用全能的document.getElementById，而不是试图为我的if语句使用pullDownReponse ..

我只是改变了这样的if语句：

 if (pullDownResponseg == "")
 {
 }

对此：

if (document.getElementById("taskThree").value == "")
 {
 }

感谢真诚的帮助。（和其他人的荒谬的非答案）

为什么＆＃34; \ n＆＃34;即使被告知不要创建新的一行？
