[英]In mobile devices' safari, <a href=“#” onclick=“return false”> doesn't work, why?
In moblie devices' safari, like iphone or ipad, <a href="#" onclick="return false">
doesn't prevent default behaviour, the page was still redirected to '#', why...? 在移动设备的游戏中,如iphone或ipad,
<a href="#" onclick="return false">
不会阻止默认行为,页面仍然被重定向到'#',为什么......? Like these html code: 像这些HTML代码:
<div style="height:1000px; width:100px"></div>
<br />
<a href="#" onclick="return false">click me</a>
When click in moblie devices' safari, it goes back to the top of the page... 当点击moblie设备的safari时,它会回到页面顶部...
I had the same problem. 我有同样的问题。 It turns out that it is a bug in the iOS 5 version of Safari.
事实证明,它是iOS 5版Safari中的一个错误。 Doesn't happen in newer or older versions, or any other browser or platform.
在较新版本或较旧版本或任何其他浏览器或平台中不会发生。
I resolved it by adding preventDefault
to the onclick event handler, in addition to the existing return false
, like so: 我解决了它,除了现有的
return false
之外,还将preventDefault
添加到onclick事件处理程序中,如下所示:
<a href="#" onclick="event.preventDefault(); return false;">click me</a>
Not ideal, but it does solve the problem. 不理想,但确实解决了这个问题。
I just kinda had the same problem with my links not working right on my friend's iPhone. 我只是有点同样的问题,我的链接不能正常在我朋友的iPhone上工作。 I deleted the
href="#"
from mine and the buttons work perfectly fine, except I have my buttons set up a little differently than you with the JavaScript. 我删除了我的
href="#"
并且按钮工作得非常好,除了我的按钮设置与JavaScript有点不同。
The way I have it set up is like this 我设置它的方式是这样的
$(document).ready(function () {
var buttons=$('#button01,#button02,#button03,#button04,#button05');
buttons.click(function(){
$(this).removeClass('off-class').addClass('on-class');
buttons.not(this).removeClass('on-class').addClass('off-class');
})
Then I trigger the frames I want to pop up with 然后我触发我要弹出的帧
if ($('#button01').hasClass('on-class')){
$('#frame01').removeClass('hidden');
$('#frame02,#frame03,#frame04,#frame05').addClass('hidden');
}else{
$('#frame01').addClass('hidden');
I don't know how you have yours set up, but removing the href="#"
with this set up worked on mine. 我不知道你是如何设置的,但是使用这个设置删除了
href="#"
。
Seems to be tricky. 似乎很棘手。 I tested with this code:
我测试了这段代码:
<body>
Hallo
<br>
<div style="height:2000px; width:100px"></div>
<br />
<a href="#" onclick="alert('click');return false;"
onmousedown="alert('down');return false;"
onmouseup="alert('up');return false;"
onmouseover="alert('over');return false;"
onmouseout="alert('out');return false;">
click me</a>
</body>
What happens is, that when I refresh the page on iPhone and tap for the first time I get: 会发生什么,当我在iPhone上刷新页面并第一次点击时,我得到:
Every next tap I get: 每下一次点击我得到:
Funny enough, this works only, when the code contains the alerts. 有趣的是,这只适用于代码包含警报的情况。 If no alerts inside code, scrolling up happens every time I tap....
如果代码中没有警报,每次点击时都会向上滚动....
For sure there's some magic with hrefs in mobile safari, which you can see, when you hold the link (without lifting the finger): An action sheet appears ("copy", "open", "open in ..." etc.) before one of the events is fired. 当你拿着链接(没有抬起手指)时,你可以看到移动游猎中的hrefs有一些神奇之处:出现一个动作表(“复制”,“打开”,“打开......”等。 ) 在其中一个事件被解雇之前。
I actually tried with 我实际上尝试过
<a href="javascript:void(0)" onclick="return false">click me</a>
and it works well 而且运作良好
Why not? 为什么不? I think, you must call a function and not only return false...
我想,你必须调用一个函数,而不仅仅是返回false ...
<a href="#" onclick="javascript:myFunction()" id="test_a">click me</a>
function myFunction() {
var elem = document.getElementById('test_a');
if (elem.addEventListener) {
elem.addEventListener('click', function() {
alert('clicked');
}, false);
} else {
elem.attachEvent('onclick', function() {
alert('clicked');
});
}
return false;
}
Firstly, try this: 首先,试试这个:
<a href="#" id='test'>click me</a>
in js: 在js中:
$('a#test').click(function(event){
event.preventDefault();
});
Secondly(if the first variant will not work): 其次(如果第一个变体不起作用):
<a href="#" id='test' onclick='return DummyFunction();'>click me</a>
in js: 在js中:
function DummyFunction(){
return false;
}
As far as i remember, one of these variant solved the same problem, when i had it. 据我所知,当我拥有它时,其中一个变体解决了同样的问题。
The first variant is much better, becouse you don't mix html and javascript 第一个变体要好得多,因为你不混用html和javascript
Basically, I went with a similar solution, but backed up a bit more with some conditional checking ... this is jQuery based and used for login in Sitefinity. 基本上,我使用了类似的解决方案,但通过一些条件检查支持了更多...这是基于jQuery并用于在Sitefinity中登录。
if ($.browser.safari) {
$('.sfSubmitBtn').attr('onclick', 'event.preventDefault(); return false;');
}
I did find that using the event.preventDefault() caused a similar issues to begin occurring in some versions of IE. 我确实发现使用event.preventDefault() 导致在某些版本的IE中开始出现类似的问题。
