jquery Uncaught SyntaxError：意外的标记ILLEGAL

Question

With $.post send data to external php

Have following code (modified variable names) text_of_the_ad:"<?php echo htmlspecialchars( substr($arr[0]["SomeText"],0,70), ENT_QUOTES, "UTF-8"); ?>",

text_of_the_ad in external php will get with $_POST['text_of_the_ad']

$arr[0]["SomeText"] is text from mysql column SomeText

In Chrome Console see text_of_the_ad:"CITROEN C4 EXCLUSIVE 2.0 HDI DIESEL 5 DOOR HATCH LOW MILEAGE FSH FULL ",

And see error Uncaught SyntaxError: Unexpected token ILLEGAL

Why the error? May be because word FULL is in the next line and after word FSH there is no ",?

Answer 1

JavaScript doesn't support multiline strings just like that. The easiest way to hack around this would probably be to just replace a literal with \ before echoing:

<?php echo str_replace("
","\
",htmlspecialchars( substr($arr[0]["SomeText"],0,70), ENT_QUOTES, "UTF-8")); ?>
