我试图在文本区域中插入新数据而不影响上一个数据的方法:
<textarea class="form-control" rows="5" id="data" name="data">
roma is the most visit
</textarea>
$("#data").val('new line without delete the previous one ');
我期望什么:
<textarea class="form-control" rows="5" id="data" name="data">
roma is the most visit
new line without delete the previous one
</textarea>
那我该怎么办呢?
