使用此AJAX函数在POST操作期间出现空格和特殊字符问题:
function comments(id,postId,user_id) {
var user_comments = encodeURIComponent($("#commentsId_"+id).val());
if(user_comments!=''){
var img = $("#img_"+id).val();
var username = "<?php echo $this->session->userdata('username'); ?>"
$.ajax({
type: "POST",
url: "<?php echo base_url() ?>social/userscomment/" +user_id+"/"+postId+"/"+user_comments,
data:{ user_comments : user_comments},
success: function(data) {
$("#commentsId_"+id).val('');
var $sparkLines = $('.comments_body_'+id);
$("#comments_add_"+id).append('<div id="id' + ($sparkLines.length + 1) + '" class="comments_body_"'+id+'><div class="feed-element comments_body_"'+id+'><a class="pull-left"><strong>'+username+' <i class="fa fa-comment-o"></i></strong></a><div class="media-body">'+user_comments+'<br></div><div class="col-lg-12"><a id="span_'+postId+'" onclick="callajaxcommcool('+postId+')" class="btn btn-xs btn-white"><i class="fa fa-star"></i><span id="span1_'+postId+'" style="display:none;">1</span> Cool </a></div></div></div></div>');
}
});
}
}
PHP控制器:
public function userscomment($comment_id,$post_id,$user_comments){
$this->load->model('comments');
$user_comments = utf8_decode(trim(mysql_real_escape_string($_POST['user_comments'])));
if(!empty($user_comments)){
$data = array("user_id" => $this->session->userdata('user_id'),
"comment_user_id" => $comment_id,
"comments" => $user_comments,
"post_id" => $post_id,
"username" => $this->session->userdata('username')
);
$this->comments->insertComments($data);
//logged user
$userRow = $this->register->get_login($this->session->userdata('user_id'));
redirect('social/userprofile/'.$userRow[0]['username']);
}
}
当用户发布评论如:“abcd”时,视图中显示的结果为:a%20b%20c%20d,如果用户尝试写一个特殊字符,比如€,我得到了这个结果%E2%82% AC
如何防止此问题?
编辑:
解决了问题是在AJAX成功函数中,我想念
'+ decodeURIComponent(user_comments)+'
success: function(data) {
$("#commentsId_"+id).val('');
var $sparkLines = $('.comments_body_'+id);
$("#comments_add_"+id).append('<div id="id' + ($sparkLines.length + 1) + '" class="comments_body_"'+id+'><div class="feed-element comments_body_"'+id+'><a class="pull-left"><strong>'+username+' <i class="fa fa-comment-o"></i></strong></a><div class="media-body">'+decodeURIComponent(user_comments)+'<br></div><div class="col-lg-12"><a id="span_'+postId+'" onclick="callajaxcommcool('+postId+')" class="btn btn-xs btn-white"><i class="fa fa-star"></i><span id="span1_'+postId+'" style="display:none;">1</span> Cool </a></div></div></div></div>');}
Edit2:我已经执行了代码,因为encodeURIComponent不允许使用这个字符〜!*()'“,我已经使用了替换功能来绕过这个限制,希望对你有所帮助。
function subcomments(id,postId,user_id) {
var user_comments = encodeURIComponent($("#commentsId_"+id).val()).replace(/\-/g, "%2D").replace(/\_/g, "%5F").replace(/\./g, "%2E").replace(/\!/g, "%21").replace(/\~/g, "%7E").replace(/\*/g, "%2A").replace(/\'/g, "%27").replace(/\(/g, "%28").replace(/\)/g, "%29");
if(user_comments!=''){
var img = $("#img_"+id).val();
var username = "<?php echo $this->session->userdata('username'); ?>"
$.ajax({
type: "POST",
url: "<?php echo base_url() ?>social/userscommentcool/" +user_id+"/"+postId+"/"+user_comments,
data:{ user_comments : user_comments },
success: function(data) {
$("#commentsId_"+id).val('');
var $sparkLines = $('.comments_body_'+id);
$("#comments_add_"+id).append('<div id="id' + ($sparkLines.length + 1) + '" class="comments_body_"'+id+'><div class="feed-element comments_body_"'+id+'><a class="pull-left"><strong>'+username+' <i class="fa fa-comment-o"></i></strong></a><div class="media-body">'+decodeURIComponent(user_comments)+'<br></div><div class="col-lg-12"><a id="span_'+postId+'" onclick="callajaxcommcool('+postId+')" class="btn btn-xs btn-white"><i class="fa fa-star"></i><span id="span1_'+postId+'" style="display:none;">1</span> Cool </a></div></div></div></div>');
}
});
}
}

在对象中传递参数时,请勿使用encodeURIComponent
。如果您自己构建URL编码的字符串,则只需要这样做。 jQuery自动编码对象中的参数,结果是它被编码两次。所以就这样做:
var user_comments = $("#commentsId_"+id).val();

您应该使用javascript decodeURI(“a%20b%20c%20d”)在您的视图中再次将其转换为“a b c d”。
使用php:
在您的视图中,在您放置编码值的行中,只需使用它:
echo urldecode("your_encoded_value");
