This code worked:
此代码有效：
this.oListItem = oList.getItemById(itemid);
ctx.load(this.oListItem);
ctx.executeQueryAsync(Function.createDelegate(this,
function () {prevText = this.oListItem.get_item('Read'); }),
function (sender, args) { alert('Error occured' + args.get_message());
});

You should use Sharepoint client object model to get the document library where you added the text column. After that you can get the list item by building a caml query with the item id and you can get the value of your column.
您应该使用 Sharepoint 客户端对象模型来获取添加文本列的文档库。之后，您可以通过使用项目 id 构建一个 caml 查询来获取列表项，并且您可以获得列的值。

You may want to use SPServicesor SharepointPlusto help you. With SharepointPlus the code would be:
您可能希望使用SPServices或SharepointPlus来帮助您。使用 SharepointPlus，代码将是：
$SP().list("Name of your list").get({fields:"Read",where:"ID = 123"}, function(data) {
if (data.length===1) alert("Read = "+data[0].getAttribute("Read"))
else alert("Unable to find ID 123")
})
