推荐答案
您的name="text"在哪里?毕竟，在jQuery中完成所有操作即可消除烦恼并开始编程.
您将使用jQuery 选择器获得元素，并使用操纵方法组添加/修改内容/属性:
http://api.jquery.com/category/selectors/ [ http://api.jquery.com/category/manipulation/ [ http://en.wikipedia.org/wiki/Jquery [ http://jquery.com/ [ ^ ].
从这里开始:
http://docs.jquery.com/Tutorials:How_jQuery_Works [ http://docs.jquery.com/Tutorials [ http://docs.jquery.com/Main_Page [
Where is yourname="text"? After all, do it all in jQuery to stop worrying and start programming.
You would get the elements using jQuery selectors and add/modify content/properties using the manipulation group of methods:
http://api.jquery.com/category/selectors/[^],
http://api.jquery.com/category/manipulation/[^].

document.getElementById('Div1').innerHTML=document.getElementById('TextArea1').value;
