将PHP转换为JS时，如何解决JavaScript不能输入中断的问题？

Question

I'm currently trying to read lines in php, (it has to be php), and logging them. This works, as i'm getting

$item1_name = $lines[1]; ----> 'MY ITEM NAME'

However, later on i have to use that $item1_name as a javascript variable:

var item1 = ' < ? php echo $item1_name ? > ';

The problem is, as i am declaring my variable, the console will output a breakline, because in my txt file, i entered a new line to declare the $item1_size.

Hence, my code will not work as javascript is experiencing an unexpected line break.

I kinda have no idea how to disable javascript from executing a breakline, as my txt file has to have multiple lines.

Help would be appreciated!

Thank you

SOLVED Trimming it directly in the variable has fixed it.

Answer 1

Probably you are splitting the text file with \\n where the text file uses \\r\\n as the line breaks. Try using:

$item1_name = trim($lines[1]);

or

var item1 = '<?php echo trim($item1_name);?>';

to eliminate the whitespace around your string.

PHP's trim function is structured like this:

trim ( string $str [, string $character_mask = " \\t\\n\\r\\0\\x0B" ] ) : string

which means the second optional parameter containing the characters [space]\\t\\n\\r\\0\\x0B defines which characters to remove from the begining and the end. You can extend them to whatever you like.
