I don't really know what I'm doing wrong. I have tried severally and it's still not working. Here is my code.
I want <p>content</P>
content to disappear after 3seconds
$loginmessage = "<br /><p class='alert alert-danger'>Login Fail</p>";
<div id="alertarea" class="text-center"><?php if(isset($loginmessage)) echo $loginmessage ?></div>
$("document").ready(function(){
function hideWithTime(){
if($("div#alertarea p").html != ""){
$(this).addClass('hideit');
}
}
// setTimeout(hideWithTime(), 2000);
hideWithTime();
});
Its html()
- a function not html
- a property
Cache your element, this
doesn't refer to $("div#alertarea > p")
$("document").ready(function(){
var element = $("div#alertarea > p");
function hideWithTime(){
if(element.html() != ""){
element.addClass('hideit');//ps bootstrap has a hide class
}
}
setTimeout(hideWithTime, 2000);
});`
If the child of the div is just a p
tag, your code finds always no html. better do:
function hideWithTime(){
if($("div#alertarea").html() != ""){
$("div#alertarea>p").addClass('hideit');
}
}
谢谢您的支持。
setTimeout (function(){ if($("div#alertarea").html() != ""){ $("div#alertarea>p").addClass('hideit'); } }, 5000);
