line-breaks

问题 I have a question, why does this: testStr="\n" testStr = "\\"+testStr print testStr >>> \ happen? Shouldn't it now print \n ? I know about the repr() function, but I would rather solve this in another way It would be very kind if you could help me 回答1: After you type testStr = "\n" the special characters are already being interpreted. So in the next line you cannot change their interpretation as it already has happened. This is being done during lexical analysis stage, so even way before the

问题 I added a ".replace" to my alert to remove/replace line breaks and hard returns and it works great. alert((foo + bar).replace(/(\n|\r)/g,'')); I want to add a similar piece to replace special characters. This works on it's own, but how do I combine the two so it removes breaks AND spec characters? .replace(/[^a-zA-Z0-9]/g,'_'); This was my best guess at it and it's not working.... alert((foo + bar).replace(/(\n|\r)/g,''),(/[^a-zA-Z0-9]/g,'_')); 回答1: If you want to replace with different

问题 I need to merge a couple of tables, once of which has a single Address field, the 2nd which as 3 address line fields. The single address field in the 1st table includes line breaks. How can I split this field into 3? Update: Turns out some records had CHR(10) || CHR(13), others CHR(13) || CHR(10), and yet others just CHAR(13). Regardless, the accepted solution below works. A useful way to tell is select dump(field) from table; 回答1: Assuming that your linebreak character is CHR(10), something

问题 I'm looping through each line of a series of CURL returned http headers, trying to detect when one ends and the next begins. I know that an http header terminates with an empty line, but what character is used to represent this line break in php? I've tried with \n but it doesn't seem to work. I certainly could be doing something wrong. What character is used to represent the line break used to terminate a header? Here's my existing code: $redirect = ''; $regs = ''; foreach ($curl_response as

问题 Here is what I am trying to do: -in Java, read a text file and create a String (preserving line breaks) -display that String in an SQL BLOB Update (or Insert) statement in the console (Eclipse), but only on one line (can't render the line breaks in the console) -copy/paste the SQL that printed in the console to Toad and execute then, -save the newly updated BLOB from Oracle to a file from Toad and have it render the line breaks Here is what i've tried so far: Here is where I read the file-

问题 I've asked this question before but I didn't seem to get the right answer. I've got a problem with new lines in text. Javascript and jQuery don't like things like this: alert('text text); When I pull information from a database table that has a break line in it, JS and jQuery can't parse it correctly. I've been told to use n2lbr(), but that doesn't work when someone uses 'shift+enter' or 'enter' when typing text into a message (which is where I get this problem). I still end up with separate

问题 I am sending an email via CodeIgniter's email->send(). I have come across an anomaly that I cannot figure out. "\r\n" is not working in a certain section of the email. However if I switch "\r\n" to "\r\n\r\n" it works. By works I mean, it adds the 2 line breaks expected. The problem area is at the bottom. $order = $this->ordersclass->getOrder( $order_id ); $quantity = $order['no_codes']; $client = $this->clientclass->getClient( $order['client_id'] ); $multi_d = $this->session->userdata('multi

问题 Apologies for what is surely a bonehead question... I am trying to create a CSV file that looks like this: Header1,Header2,Header3, "Value1","Value2","Value3" Instead, I'm getting a CSV file that looks like this: Header1,Header2,Header3,\r\n"Value1","Value2","Value3" How do I get my CRLF characters to actually produce line breaks in my output? What I'm doing is making an ajax call to a WebMethod that generates a datatable from a stored proc. That datatable is then parsed out to a CSV like so:

问题 I have this code in my admin.php file: <?php include("include/php/auth.inc.php"); ?> <?php if (user_Type() != "admin") {header("location: index.php"); exit(0);} ?> <?php include("include/php/admin/admin.inc.php"); ?> <?php include("header.php"); ?> <?php include ("menu.php"); ?> <?php include ("admin_Panel.php"); ?> <?php include "footer.php" ?> At line 3 I included a PHP file named admin.inc.php , this file contains only some functions and does not contain any HTML tag or any character

问题 I have a fiddle which I have replicated from a particular design. The section of the screenshot I have attached below in the problem statement. Problem Statement: I am wondering what changes I should make in the fiddle so that I am able to give the line break between the following lines as shown in the screenshot which is the present in the fiddle as well. The snippets of HTML codes which I have used in the fiddle for the above lines are: <tr> <td style="padding-bottom: 3%;text-align:right;"
