回声添加 <br> 默认情况下是什么原因？

Question

jquery

$('registration').click(function() {
       $.post('check_code.php',
        {lemail:$('input#pro_id').val(),ccode:$('input#ccode').val()},function(result){
        alert(result+"hello");
    });     
});

check_code.php

 <?php session_start();

 include("configure.php");

$email =  $_POST['lemail'];
$ccode  =  $_POST['ccode'];

 echo $email; ?>

The php file echoes with a new line I guess <br /> tag, when I alert I get this as output:

 someemail@example.com
   // why does i get this break line
 hello

I don't want a break line, what would be the cause? I have been checking for the bug but unable to figure it out.

Answer 1

What's happening here is a "normal" line break as if you would hit Enter , not a <br> tag.

Make sure there are no hidden line breaks after the closing ?> .

To avoid this happening, you can remove the ?> altogether. PHP doesn't require it at the end of the file.

Answer 2

change your php like this:

 <?php 
session_start();
include("configure.php");

$email =  $_POST['lemail'];
$ccode  =  $_POST['ccode'];
$email =  str_replace(array("\n", "\r"), '', $email );

 echo $email; 
?>

and just in case your jquery like this:

$('registration').click(function() {
       $.post('check_code.php',
        {lemail:$('input#pro_id').val(),ccode:$('input#ccode').val()},function(result){
        alert($.trim(result+"hello"););
    });     
});

Answer 3

check #ccode and #proid css values, and see if they are display: block; . Change them to display: inline;

edit:

Also check to see if the texts are not in separate block elements. Like the <div> element that you mention in the comments. Change <div> in <span> for example.
