我有这份代码,在其中添加了return false;,以保证它执行完毕后不会在url末尾添加#符号,但是它仍然会这样做。你们有什么想法,我做错了什么,应该在哪里添加return false;?
// Called right away after someone clicks on the vote up link
$('.vote_up').mouseup(function()
{
$("#loading").show();
var problem_id = $(this).attr("data-problem_id");
vote(problem_id , 1);
//Return false to prevent page navigation
return false;
});
$('.vote_down').mouseup(function()
{
$("#loading").show();
problem_id = $(this).attr("data-problem_id");
vote ( problem_id , -1 );
//Return false to prevent page navigation
return false;
});
// Global function
var vote = function(problem_id , vote)
{
var dataString = 'problem_id=' + problem_id + '&vote=' + vote;
// The person is actually logged in so lets have him vote
$.ajax({
type: "POST",
url: "/auth/check_login.php",
dataType: "json",
success: function(data)
{
$.ajax({
type: "POST",
url: "/problems/vote.php",
data: dataString,
success: function(html)
{
$("#loading").hide();
if ( html == "not_logged_in" )
{
queue.login = false;
//set the current problem id to the one within the dialog
$problemId.val(problem_id);
// Try to create the popup that asks user to log in.
$("#loginpopup").dialog( {title: 'Please Login To Vote'} ); // title: 'Login Dialog'
// prevent the default action, e.g., following a link
return false;
}
else
if ( html == "already_voted" )
{
// Display a dialog box saying that the user already voted
$('<div>You already voted this way on this problem.</div>').dialog( {title: 'Already Voted'});
// show div which says un-important, hide div which says important
$("#support").hide();
$("#dont_support").show();
return false;
}
else
if ( html == "error_getting_vote" )
{
$('<div />').html('Error getting existing votes.').dialog();
}
else
{
if ( vote == -1 )
{
$("#support").show();
$("#dont_support").hide();
}
else
{
$("#support").hide();
$("#dont_support").show();
}
// Now make a call to AJAX to get the count of votes
$.ajax({
type: "POST",
url: "/problems/get_vote_count.php",
data: dataString,
success: function(html)
{
var class_name = ".votes_"+problem_id;
$(class_name).text(html);
return false;
}
});
return false;
}
},
error: function(html)
{
$("#loading").hide();
return false;
} // End of error case
}); // Closing inner AJAX call.
},
error: function(data)
{
$("#loading").hide();
$("#loginpopup").dialog( {title: 'Please Login To Vote'} );
return false;
} // End of error
}); // End of outer AJAX.
return false;
};
e
)传递给事件回调函数并使用e.preventDefault();
,而不是使用return false;
。如果return false;
无法解决问题,也不要认为这样做会修复它。 - Robin
