使用javascript / jquery设置TD内容(Setting TD content using javascript/jquery)

 我试图在javascript函数中替换td标记的内容，但无法弄清楚发生了什么。 这是功能。 
 
function actionCompleted(response, status, data) {

    // Set the id for row
    var rowId = "#rowId-" + response.fieldname;

    // Set the ids for the two table cells we need
    var tdstatusId = "#tdstatusId-" + response.id;
    var tdreasonId = "#tdreasonId-" + response.id;
    alert(tdreasonId);

    try {
        //get the table cell for the status
        var tdstatus = $('#itemDetails').find(rowId).find(tdstatusId);
        //get the table cell for the reason
        var tdreason = $('#itemDetails').find(rowId).find(tdreasonId);

        //Make sure we found our cells
        if (tdstatus != null && tdreason != null) {
            //Set our cell content
            //tdstatus.html(response.ChangeStatus);
            //tdreason.text(response.message); 
            tdstatus.html('TEST');
            tdreason.text('TEST'); 
        }
    }
    catch (e) {
        alert(e.toString());
    }
}
 
 我首先想到jquery找到td控件可能有问题，所以我添加了null检查。 
 
 然后我认为它是.text（）所以我尝试了.html（）。 
 
 我想也许是吞下一个例外所以我添加了try..catch。 
 
 然后我认为这可能是函数收到的响应对象的问题，所以我在那里扔了一些警报，它们有我需要的值。 
 
 我检查了ID并确保它们匹配页面html中找到的id。 
 
 我已经检查了我能想到的一切。 但我的代码根本不起作用。 我试图设置的两个TD元素中的第一个包含两个链接（一个标签），但第二个是空的。 所以我认为这与它无关。 我在这里试图解决这个问题。 
 
 有什么我做错了吗？ 可能还有其他会导致这种行为的事情吗？ 
 
 提前致谢。 

I'm trying to replace the contents of a td tag in a javascript function but can't figure out what's going on. Here is the function.
 
function actionCompleted(response, status, data) {

    // Set the id for row
    var rowId = "#rowId-" + response.fieldname;

    // Set the ids for the two table cells we need
    var tdstatusId = "#tdstatusId-" + response.id;
    var tdreasonId = "#tdreasonId-" + response.id;
    alert(tdreasonId);

    try {
        //get the table cell for the status
        var tdstatus = $('#itemDetails').find(rowId).find(tdstatusId);
        //get the table cell for the reason
        var tdreason = $('#itemDetails').find(rowId).find(tdreasonId);

        //Make sure we found our cells
        if (tdstatus != null && tdreason != null) {
            //Set our cell content
            //tdstatus.html(response.ChangeStatus);
            //tdreason.text(response.message); 
            tdstatus.html('TEST');
            tdreason.text('TEST'); 
        }
    }
    catch (e) {
        alert(e.toString());
    }
}
 
I first thought there might be a problem with jquery finding the td controls, so I added the null check. 
 
Then I thought it was the .text() so I tried .html(). 
 
I thought maybe it was swallowing an exception so I added the try..catch.
 
Then I thought it might be an issue with the response object the function received, so I threw some alerts in there and they have the values I need.
 
I checked the Ids and made sure they matched the id's found in the html of the page.
 
I've checked everything I could think of. But my code simply doesn't work. The first one of the two TD elements I'm trying to set contains two links (a tags), but the second one is empty. So I don't think that has anything to do with it. I'm at wits end here trying to figure this out.
 
Is there something I'm doing wrong? Could there be something else that would cause this behavior?
 
Thanks in advance.
