我有用于上传图像的 PHP 和 JS 脚本。PHP 文件返回一个 varerr:type
并且我正在检查 JS if return == err:type
,但它不起作用。
$(document).ready
(
function()
{
$('#avatar_image_upload_form').submit
(
function()
{
$('div#avatar_ajax_upload_demo img').attr('src','../../Files/Border/loading.gif');
}
);
$('iframe[name=avatar_upload_to]').load(
function()
{
var result = $(this).contents().text();
if(result !='')
{
$('div#avatar_ajax_upload_demo img').attr('src',result);
if(result == 'err:size')
{
$('div#avatar_ajax_upload_demo img').attr('src','../../Files/Border/avatar_big.jpg');
}
if (result == 'err:type')
{
$('div#avatar_ajax_upload_demo img').attr('src','../../Files/Border/avatar_invalid.jpg');
}
}
}
);
}
);
if(result == 'err:type')
不起作用,但是result = "err:type"
