问题描述

如何在使用jquery显示错误消息时放置换行符？

下面是我的代码。



for（var i in testids ）

{

singid = singid + testids [i] +，;

}



$（＃errmsg）。text（singid）;



i希望在单独的行中显示id，即不用逗号作为分隔符我想换线。

i试过

singid = singid + testids [i] +
;

singid = singid + testids [i] +\ n;

singid = singid + testids [i] +\ b;

singid = singid + testids [i ] +
;

但没有运气。

有人知道如何放假吗？

推荐答案

（＃errmsg）。text（singid）;



i希望在单独的行中显示id，即不要使用逗号作为我想要的分隔符换行。

i试过

singid = singid + testids [i] +
;

singid = singid + testids [I] +\\ \\ n;

singid = singid + testids [i] +\ b​​;

singid = singid + testids [i] +
;

但没有运气。

由于输出是HTML，你需要使用 < br> 标记 [ ^ ]：

Since the output is HTML, you need to use the <br> tag[^]:

singid = singid + testids[i] + "<br>";

但是，您使用 text 方法来显示错误消息，该消息将自动对输出进行HTML编码，包括< br> 标记。



相反，您需要对每条错误消息进行HTML编码，然后使用 html 方法显示错误：

However, you're using the text method to display the error message, which will automatically HTML-encode the output, including the <br> tag.

Instead, you'll need to HTML-encode each error message, and then use the html method to display the error:

function htmlEncode(value){
    return

（ < span class =code-string>< div />）。text（value）.html（）;
}

...

for （ var i in testids）
{
singid = singid + htmlEncode（testids [i]）+ < br>;
}

("<div/>").text(value).html(); } ... for (var i in testids) { singid = singid + htmlEncode(testids[i]) + "<br>"; }
