从带引号的表单调用setTimeout(calling setTimeout from a form with quotes)

 我有一个用于上传文件的html表单，如下所示： 
 
$uploadhtml = htmlspecialchars(json_encode("<form action='up.php' method='post'
enctype='multipart/form-data'>
<label for='file'>Filename:</label>
<input type='file' name='file' id='file'/> 
<br />
<input type='hidden' name='pk' value='".$pk."'>
<input type='hidden' name='username' value='".$USERNAME."'>
<input type='submit' name='submit' value='Submit' onclick= />
</form>"), ENT_QUOTES);
 
 我想知道是否可以调用s etTimeout函数来更新特定的层，如下所示： 
 
onclick="setTimeout('updateLayer("text", "ff", "ok"))',1250);"
 
 updateLayer将3个变量作为参数，如何将它们指定为引号内的参数？ 

I have a html form for uploading a file, which is as follows:
 
$uploadhtml = htmlspecialchars(json_encode("<form action='up.php' method='post'
enctype='multipart/form-data'>
<label for='file'>Filename:</label>
<input type='file' name='file' id='file'/> 
<br />
<input type='hidden' name='pk' value='".$pk."'>
<input type='hidden' name='username' value='".$USERNAME."'>
<input type='submit' name='submit' value='Submit' onclick= />
</form>"), ENT_QUOTES);
 
I would like to know if it is possible to call the setTimeout function to update a particular layer, like follows:
 
onclick="setTimeout('updateLayer("text", "ff", "ok"))',1250);"
 
updateLayer takes 3 variables as arguments, how would I specify them as parameters within quotes?
