Question

Chrome控制台中的某些错误消息并且未显示预期结果。无法辨认出来什么代码段产生它。所以没有其他方式，我只是在这里贴了代码

控制台说：

未捕获的ReferenceError：未定义meraj_63193201111201321808488_white

，它给出的行号是95.

但是在第95行，我有：

警告（“成功价值=”+ arg2）;

我想做什么：

使用jquery-ui，我使用了一个用于IMAGE FILE上传的对话框。文件上传后，我想在photo_upload_preview_indiv类中显示它的预览。

HTML

<div id="dialog" title="Upload Your Profile Picture">
    <form action="upload.php" method="post" enctype="multipart/form-data" target="upload_target" onsubmit="startUpload();"                             style="border1111111:1px solid yellow; margin-top:0px">
        <p id="f1_upload_form" align="center"><!--<br/>-->
            <label>
                <br>File:  
                <input name="myfile" type="file" size="30" />
            </label>
            <label>
                <input type="submit" name="submitBtn" class="sbtn" value="Upload" />
            </label>
        </p>
        <p id="f1_upload_process">Loading...<br/><img src="img/loader.gif" /><!--<br/>--></p>
        <iframe id="upload_target" name="upload_target" src="#" style="width:0;height:0;border:0px solid #fff;"></iframe>
    </form>

    <div class="photo_upload_previews">
        <div class="photo_upload_preview_indiv"></div><!-- end of class photo_upload_preview_indiv-->
    </div><!--end of class photo_upload_previews -->
</div><!-- end of id dialog -->

的JavaScript

<script type="text/javascript">//<![CDATA[
    $(document).ready(function () {
        var dialog = $('#dialog');

        dialog.dialog({
            width:860,

        document.getElementById('f1_upload_form').style.visibility = 'visible';

upload.php的

    $destination_path = getcwd().DIRECTORY_SEPARATOR;

    $result = 0;

    $target_path = $destination_path .'uploads/'.basename( $_FILES['myfile']['name']);

        $result = 1;
    }

    sleep(1);
    $_SESSION['uploaded_file_name']=$_FILES['myfile']['name'].$_FILES["file"]["type"];
    $uploaded_file_name=$_SESSION['uploaded_file_name'];

Answer 1

这不是你的JS的第95行，而是由包含内联JS的页面生成的HTML的第95行。上传文件的名称似乎报价不正确。我确实看到你当前输出的引号，但我会仔细检查输出到浏览器的输出。
