Question

我有两个文件 index.php和code2.js

在inde.php中我定义了四个这样的预标签

<pre class="codeguru">hsduic</pre>
Let us now look at how PHP determines the data type depending on the attributes of the supplied data.
<pre class="codeguru">say 'hello';</pre>
Floating point numbers
<pre class="codeguru">say 'you r amazing';</pre>
Character strings
<pre class="codeNrun">say 'i am fine';</pre>

在code2.js的帮助下，我用textarea替换了那个pre标签。并使用此textarea运行perl.now的代码一切正常，但我已经定义错误代码不起作用。所以我给你index.php和code2.js的完整代码的index.php

<p>Integer : whole numbers e.g. -3, 0, 69. The maximum value of an integer is platform-dependent. On a 32 bit machine, its usually around 2 billion. 64 bit machines usually have larger values. The constant PHP_INT_MAX is used to determine the maximum value.

        document.getElementById('log-result' + idx).innerHTML += "Error:\n";
        document.getElementById('log-result' + idx).innerHTML += err + "\n";
        document.getElementById('log-result' + idx).innerHTML += "Compilation aborted.\n";
    } 
}

我在log-result中打印错误但我不能。请帮我这样做。这是现场演示，以帮助理解我的问题。点击这里进行现场演示 http://jsfiddle.net/Sanjayrathod/PknGC/1/

你没有改变“log-result”的id，你只是为了打印结果：

$(form).find('#print-result4').first().attr('id', 'print-result' + idIndex++);

所以添加这样的一行：

$(form).find('#log-result').first().attr('id', 'log-result' + idIndex++);

如何将错误打印到div标签？
