json_encode转义特殊字符

Question

I would like to pass a php array to a jQuery function.
I tried to send the array as json_encode like this:

<button onclick='callFunction(<? echo json_encode($myArray); ?>)'></button>

the result of my json_encode array is:

{"Date":"2018-01-26 12:55:00","Details":"FORLI IT"}

All works good.

But if I have an array like this (with a ' )

{"Date":"2018-01-26 12:55:00","Details":"FORLI' IT"}

My function doesn't work anymore - my console will show:

SyntaxError: Unexpected EOF

How can I solve this problem?

Answer 1

尝试使用和addslashes ，

<button onclick='callFunction(<? echo json_encode(addslashes($myArray)); ?>)'></button>

Answer 2

The way I suggest you deal with anything that goes to html is:

<button onclick='callFunction(<? echo htmlentities(json_encode($myArray),ENT_QUOTES); ?>)'></button>

Check all available flags at http://php.net/manual/en/function.htmlentities.php

This one uses the flag ENT_QUOTES because the default behaviour is to only encode double quotes. Using ENT_QUOTES will also encode single quotes.
