它看起来像这样:
<?php
if( stristr($_SERVER['PHP_SELF'], 'blog') == FALSE )
{
echo "<div id="stuff"></div>";
}
?>
问题是......它不起作用......当我加载www.url.com/blog时,div#stuff仍然显示.
我只是缺乏睡眠或上述工作吗？如果网址包含博客,你会做什么没有div显示？
我有一些简单的事情,我想用更少的重复来完成.
默认情况下,我想要显示一个div,但是如果$ x == 1,那么检查是否$ y!= 1,如果$ y没有,则不显示该块.
然而,我能想到的最好的是以下内容:
if($x) {
if($y != 1) {
echo '<div>display block</div>';
}
} else {
echo '<div>display block</div>';
}
这看起来有点重复.
我知道我可以调整一下,做一些像:
$displayBlock = '<div>display block</div>';
if($x) {
if($y != 1) {
echo $displayBlock;
}
} else {
echo $displayBlock;
}
但即使如此,我还是觉得有一种方法可以做到这一点,如果还有其他我现在看不到的东西.
如何用较少的if语句完成上述操作？所以:如果$ x!= 1(默认值),则显示displayBlock.如果$ x == 1,$ y!= 1,则显示显示块.如果$ x == 1 && $ y == 1,则不显示displayBlock.
我有一个简单的'处理' 点等待...点等待...点等待..当用户提交表单时.
我认为这可以通过类似的东西轻松完成
<h2>Processing</h2>
和
$(document).ready(function(){
setTimeout($('h2').append('.'), 500);
});
然而,它得到第一个点,然后抛出一个错误:
Uncaught SyntaxError: Unexpected identifier
我的逻辑在哪里失败了？什么是意外的标识符？
